  • Using libcurl to create a valid POST

    - by Haraldo
    static int get( const char * cURL, const char * cParam ) { CURL *handle; CURLcode result; std::string buffer; char errorBuffer[CURL_ERROR_SIZE]; //struct curl_slist *headers = NULL; //headers = curl_slist_append(headers, "Content-Type: Multipart/Related"); //headers = curl_slist_append(headers, "type: text/xml"); // Create our curl handle handle = curl_easy_init(); if( handle ) { curl_easy_setopt(handle, CURLOPT_ERRORBUFFER, errorBuffer); //curl_easy_setopt(handle, CURLOPT_HEADER, 0); //curl_easy_setopt(handle, CURLOPT_HTTPHEADER, headers); curl_easy_setopt(handle, CURLOPT_POST, 1); curl_easy_setopt(handle, CURLOPT_POSTFIELDS, cParam); curl_easy_setopt(handle, CURLOPT_POSTFIELDSIZE, strlen(cParam)); curl_easy_setopt(handle, CURLOPT_FOLLOWLOCATION, 1); curl_easy_setopt(handle, CURLOPT_WRITEFUNCTION, Request::writer); curl_easy_setopt(handle, CURLOPT_WRITEDATA, &buffer); curl_easy_setopt(handle, CURLOPT_USERAGENT, "libcurl-agent/1.0"); curl_easy_setopt(handle, CURLOPT_URL, cURL); result = curl_easy_perform(handle); curl_easy_cleanup(handle); } if( result == CURLE_OK ) { return atoi( buffer.c_str() ); } return 0; } Hi there, first of all I'm having trouble debugging this in visual studio express 2008 so I'm unsure what buffer.c_str() might actually be returning but I am outputting 1 or 0 to the web page being posted to. Therefore I'm expecting the buffer to be one or the other, however I seem to only be returning 0 or equivalent. Does the code above look like it will return what I expect or should my variable types be different? The conversion using "atoi" may be an issue. Any thought would be much appreciated.

  • Whats wrong with my cookies?

    - by William
    For some reason This php script won't echo my cookie variable: <?php require 'connection.php'; require 'variables.php'; $name = $_POST['name']; $pass = $_POST['pass']; if(($name == $admin_name) && ($pass == $admin_pass)){ setcookie($forum_url."name",$name,time()+604800); setcookie($forum_url."pass",$pass,time()+604800); } else echo 'Failed'; ?> heres the html that gets sent to admin_login.php <form method=post action=admin_login.php> <div id="formdiv"> <div class="fieldtext1">Name</div> <div class="fieldtext1">Pass</div> <input type="text" name=name size=25 /> <input type="password" name=pass size=25 /> </div> <input type=submit value="Submit" id="submitbutton"> </form> here is the index, where I want the info echoed <?php echo $_COOKIE[$forum_url."name"]; ?> What am I doing wrong?

  • UIViewController remaining

    - by Guy
    Hi Guys. I have a UIViewController named equationVC who's user interface is being programmatically created from another NSObject class called equationCon. Upon loading equationVC, a method called chooseInterface is called from the equationCon class. I have a global variable (globalVar) that points to a user defined string. chooseInterface finds a method in the equationCon class that matches the string globalVar points to. In this case, let's say that globalVar points to a string that is called "methodThatMatches." In methodThatMatches, another view controller needs to show the results of what methodThatMatches did. methodThatMatches creates a new equationVC that calls upon methodThatMatches2. As a test, each method changes the color of the background. When the application starts up, I get a purple background, but as soon as I hit backwards I get another purple screen, which should be yellow. I do not think that I am release the view properly. Can anyone help? -(void)chooseInterface { NSString* equationTemp = [globalVar stringByReplacingOccurrencesOfString:@" " withString:@""]; equationTemp = [equationTemp stringByReplacingOccurrencesOfString:@"'" withString:@""]; SEL equationName = NSSelectorFromString(equationTemp); NSLog(@"selector! %@",NSStringFromSelector(equationName)); if([self respondsToSelector:equationName]){ [self performSelector:equationName]; } } -(void)methodThatMatches{ self.equationVC.view.backgroundColor = [UIColor yellowColor]; [setGlobalVar:@"methodThatMatches2"]; EquationVC* temp = [[EquationVC alloc] init]; [[self.equationVC navigationController] pushViewController:temp animated:YES ]; [temp release]; } -(void)methodThatmatches2{ self.equationVC.view.backgroundColor = [UIColor purpleColor]; }

  • C++ Returning a Reference

    - by Devil Jin
    Consider the following code where I am returning double& and a string&. The thing works fine in the case of a double but not in the case of a string. Why is this difference in the behavior? In both the cases compiler does not even throws the Warning: returning address of local variable or temporary as I am returning a reference. #include <iostream> #include <string> using namespace std; double &getDouble(){ double h = 46.5; double &hours = h; return hours; } string &getString(){ string str = "Devil Jin"; string &refStr = str; return refStr; } int main(){ double d = getDouble(); cout << "Double = " << d << endl; string str = getString(); cout << "String = " << str.c_str() << endl; return 0; } Output: $ ./a.exe Double = 46.5 String =

  • is this uibutton autoreleased ?

    - by dubbeat
    HI This is just a question to check my sanity really. I'm hunting memory leaks that show up in instruments but not the static analyzer. In one spot the analyzer is pointing to this block of code UIButton *randomButton = [UIButton buttonWithType:UIButtonTypeRoundedRect ]; randomButton.frame = CGRectMake(205, 145, 90, 22); // size and position of button [randomButton setTitle:@"Random" forState:UIControlStateNormal]; randomButton.backgroundColor = [UIColor clearColor]; randomButton.adjustsImageWhenHighlighted = YES; [randomButton addTarget:self action:@selector(getrandom:) forControlEvents:UIControlEventTouchUpInside]; [self.view addSubview:randomButton]; For some reason I thought the above code would auto release the button because I'm not calling init or alloc? If I add [randombutton release] at the bottom of the code my button fails to show. Could somebody describe to me the correct way to release a button from memory that is created in the above way? Or would I be better off making the button a class variable and sticking the release in the dealloc method?

  • Read HTML file into email

    - by cast01
    Ive written a script to send html emails and all works well. I have the email stored in a separate HTML file which is then read in usin a while loop and fgets(). However, i want to be able to pass variables into the html. For example, in a html file i may have something like.. <body> Dear Name <br/> Thank you for your recent purhcase </body> and i read this into a string like so $file = fopen($filename, "r"); while(!feof($file)) { $html.= fgets($file, 4096); } fclose ($file); I want to be able to replace "Name" in the html file by a variable and im not entirely sure on the best way to do this. I could always make my own tag and then use regex to replace that with the name once ive read the file into the string, but im wondering if there is a better/easier method to do this. (On a side note, if anyone knows whether its better to use file_get_contents instead of multiple calls to fgets, id be interested to know)

  • Warning in image_graphviz

    - by garcon1986
    Hello, I have got a warning in image_graphviz, i have viewed a post, who has a similar error. I have installed pear image_graphviz package(Image_GraphViz-1.2.1), I also installed graphviz.msi(Graphviz2.25.msi) in windows(But i don't know if does something with image_graphviz and if it does have some effects when i use image_graphviz). Do i need to do something else? Here is my code from pear image_graphviz site. <?php require_once 'Image/GraphViz.php'; error_reporting(E_ALL ^ E_NOTICE); //Added E_NOTICE $gv = new Image_GraphViz(); $gv->addEdge(array('wake up' => 'visit bathroom')); $gv->addEdge(array('visit bathroom' => 'make coffee')); $gv->image(); ?> This is the warning: Warning: fopen(C:\WINDOWS\Temp\gra50.tmp.svg) [function.fopen]: failed to open stream: No such file or directory in C:\wamp\bin\php\php5.3.0\PEAR\Image\GraphViz.php on line 210 Notice: Undefined variable: data in C:\wamp\bin\php\php5.3.0\PEAR\Image\GraphViz.php on line 218 Thanks Pekka Gaiser, I used error_reporting(E_ALL ^ E_NOTICE);.

  • How to add text to email sent from a php contact form

    - by JustStatic
    Hi all this is the PHP im using: <?php $name = $_POST['name']; $email = $_POST['email']; $phone = $_POST['phone']; $message = $_POST['message']; $formcontent=" From: $name \n Phone: $phone \n Message: $message"; $recipient = "[email protected]"; $subject = "Contact Form"; $mailheader = "From: $email \r\n"; mail($recipient, $subject, $formcontent, $mailheader) or die("Error!"); echo "Thank You!" . " -" . "<a href='contact.html' style='text-decoration:none; color:#ff0099;'> Return Home</a>"; ?> Its working perfectly fine but i would like there to be some text sent with this email that says "This is from your website" or something similar to tell the recipient that it isnt spam (my client isn't tech friendly and sees everything plain text as spam). I'm very new to PHP with nearly 0 knowledge and have no idea how to add something like that. I did have a go at making a new variable with the string inside and then include that in the: mail($recipient, $subject, $formcontent, $mailheader) or die("Error!"); line but with no success. Thanks for taking the time any help would be welcome.

  • How can I fix this clang warning: "Object with +0 retain counts returned to caller where +1 (owning)

    - by mipadi
    I have a piece of Objective-C code that looks like the following: - (NSString *)copyData:(NSData *)data { NSString *path = [[[self outputDirectory] stringByAppendingPathComponent:@"archive"] stringByAppendingPathExtension:@"zip"]; NSLog(@"Copying data to %@", path); [data writeToFile:path atomically:NO]; return path; } The code is called from an initializer that looks like this: - (id)initWithData:(NSData *)data { if ((self = [super init]) != nil) { NSString *path = [self copyData:data]; // Line 41 (referenced in warning, shown below) return [self initWithContentsOfFile:path]; } return self; } When running the clang static analyzer, I get the following warnings for the path variable: Potential leak of an object allocated on line 41 and stored into 'path' Object with +0 retain counts returned to caller where +1 (owning) retain count is expected I'm confused. My understanding is that stringByAppendingPathComponent should not return an autoreleased string, so it should have a net retain count of 0. (Obviously I don't want to retain it.) I've tried altering copyData: to return the following, but it didn't get rid of the warning: return [[path retain] autorelease]; So what's the deal with this warning?

  • Improve performance of searching JSON object with jQuery

    - by cale_b
    Please forgive me if this is answered on SO somewhere already. I've searched, and it seems as though this is a fairly specific case. Here's an example of the JSON (NOTE: this is very stripped down - this is dynamically loaded, and currently there are 126 records): var layout = { "2":[{"id":"40","attribute_id":"2","option_id":null,"design_attribute_id":"4","design_option_id":"131","width":"10","height":"10", "repeat":"0","top":"0","left":"0","bottom":"0","right":"0","use_right":"0","use_bottom":"0","apply_to_options":"0"}, {"id":"41","attribute_id":"2","option_id":"115","design_attribute_id":"4","design_option_id":"131","width":"2","height":"1", "repeat":"0","top":"0","left":"0","bottom":"4","right":"2","use_right":"0","use_bottom":"0","apply_to_options":"0"}, {"id":"44","attribute_id":"2","option_id":"118","design_attribute_id":"4","design_option_id":"131","width":"10","height":"10", "repeat":"0","top":"0","left":"0","bottom":"0","right":"0","use_right":"0","use_bottom":"0","apply_to_options":"0"}], "5":[{"id":"326","attribute_id":"5","option_id":null,"design_attribute_id":"4","design_option_id":"154","width":"5","height":"5", "repeat":"0","top":"0","left":"0","bottom":"0","right":"0","use_right":"0","use_bottom":"0","apply_to_options":"0"}] }; I need to match the right combination of values. Here's the function I currently use: function drawOption(attid, optid) { var attlayout = layout[attid]; $.each(attlayout, function(k, v) { // d_opt_id and d_opt_id are global scoped variable set elsewhere if (v.design_attribute_id == d_att_id && v.design_option_id == d_opt_id && v.attribute_id == attid && ((v.apply_to_options == 1 || (v.option_id === optid)))) { // Do stuff here } }); } The issue is that I might iterate through 10-15 layouts (unique attid's), and any given layout (attid) might have as many as 50 possibilities, which means that this loop is being run A LOT. Given the multiple criteria that have to be matched, would an AJAX call work better? (This JSON is dynamically created via PHP, so I could craft a PHP function that could possibly do this more efficently), or am I completely missing something about how to find items in a JSON object? As always, any suggestions for improving the code are welcome! EDIT: I apologize for not making this clear, but the purpose of this question is to find a way to improve the performance. The page has a lot of javascript, and this is a location where I know that performance is lower than it could be.

  • Flex wordwrap issue with multiple text instances

    - by Craig Myles
    Hi, I have a scenario where I want to dynamically add words of text to a container so that it forms a paragraph of text which is wrapped neatly according to the size of the parent container. Each text element will have differing formatting, and will have differing user interaction options. For example, imagine the text " has just spoken out about ". Each word will be added to the container one at a time, at run time. The username in this case would be bold, and if clicked on will trigger an event. Same with the news article. The rest of the text is just plain text which, when clicked on, would do nothing. Now, I'm using Flex 3 so I don't have access to the fancy new text formatting tools. I've implemented a solution where the words are plotted onto a canvas, but this means that the words are wrapped at a particular y position (an arbitrary value I've chosen). When the container is resized, the words still wrap at that position which leaves lots of space. I thought about adding each text element to an Array Collection and using this as a datasource for a Tile List, but Tile Lists don't support variable column widths (in my limited knowledge) so each word would use the same amount of space which isn't ideal. Does anyone know how I can plot words onto a container so that I can retain formatting, events and word wrapping at paragraph level, even if the container is resized?

  • How does an NSTextField know that it's value has changed?

    - by Brian Postow
    I have a textfield that can either be edited by hand, or set through another control. (It's a page number, so you can jump to page 16 by typing in 16, or you can page up and down with the next/prev buttons) I have the value of the text field bound to an int page variable. It seems to work correctly, when you type a page number in, it jumps, when you page up and down, the page number in the text box changes appropriately. However, at some level, when I page up and down, the text box doesn't seem to know that it's value has changed, because if I type 1 it doesn't do anything. It doesn't call the bound set-method or anything. It looks like the textfield is thinking "I'm already 1, so I don't need to do anything." Even though it was 5 because I hit next 4 times. If I type an number other than 1, it goes there. If I THEN type 1, it goes to page 1, because now it thinks it's on that other page. The problem seems to be that I'm changing the value of the textfield programatically, but some part isn't getting the message. Does this seem like a reasonable explanation? And either way, any ideas on what's causing it? thanks

  • how do i work bool!

    - by user350217
    HI! im a beginner and im really getting frustrated with this whole concept. i dont understand how to exactly use the bool function. i know what it is but i cantfigure out how to make it work in my program. Im trying to say that if my variable "selection" is any letter beween 'A' and 'I' then it is valid and can continue on to the next function which is called calcExchangeAmt(amtExchanged, selection). if it is false i want it to ask the user if they want to repeat the program and if they agree to repeat i want it to clear the screen and restart to the main function. please help edit my work! this is my bool function: bool isSelectionValid(char selection, char yesNo, double amtExchanged) { bool validData; validData = true; if((selection >= 'a' && selection <= 'i') || (selection >= 'A' && selection <= 'I')) { validData = calcExchangeAmt (amtExchanged, selection); } else(validData == false); { cout<<"Do you wish to continue? (Y for Yes / N for No)"; cin>>yesNo; } do { main(); } while ((yesNo =='y')||(yesNo == 'Y')); { system("cls"); } return 0; } this is the warning that im gettng: warning C4800: 'double' : forcing value to bool 'true' or 'false' (performance warning)

  • Why do I get CA1806 when I catch exception in C++/CLI?

    - by brickner
    I've recently upgraded my project from Visual Studio 2008 to Visual Studio 2010. By enabling Code Analysis and compiling in Release, I'm getting warning CA1806: Do not ignore method results. I've managed to reduce the code that produces the warning to this code: .h file: public ref class Foo { public: void Bar(); }; .cpp file: void Foo::Bar() { try { } catch (const std::exception&) // here I get the warning { } } the warning: CA1806 : Microsoft.Usage : 'Foo::Bar(void)' calls 'Global::__CxxRegisterExceptionObject(void*, void*)' but does not use the HRESULT or error code that the method returns. This could lead to unexpected behavior in error conditions or low-resource situations. Use the result in a conditional statement, assign the result to a variable, or pass it as an argument to another method. If I try to use the exception value or do catch(...) the warning still appears. If I catch managed exceptions instead or compile in Debug I don't get the warning. Why do I get this warning? UPDATE I've decided to open a bug report on Microsoft Connect.

  • strange behavior in python

    - by fsm
    The tags might not be accurate since I am not sure where the problem is. I have a module where I am trying to read some data from a socket, and write the results into a file (append) It looks something like this, (only relevant parts included) if __name__ == "__main__": <some init code> for line in file: t = Thread(target=foo, args=(line,)) t.start() while nThreads > 0: time.sleep(1) Here are the other modules, def foo(text): global countLock, nThreads countLock.acquire() nThreads += 1 countLock.release() """connect to socket, send data, read response""" writeResults(text, result) countLock.acquire() nThreads -= 1 countLock.release() def writeResults(text, result): """acquire file lock""" """append to file""" """release file lock""" Now here's the problem. Initially, I had a typo in the function 'foo', where I was passing the variable 'line' to writeResults instead of 'text'. 'line' is not defined in the function foo, it's defined in the main block, so I should have seen an error, but instead, it worked fine, except that the data was appended to the file multiple times, instead of being written just once, which is the required behavior, which I got when I fixed the typo. My question is, 1) Why didn't I get an error? 2) Why was the writeResults function being called multiple times?

  • Conditional "Get Script File" in Javascript without using a library function

    - by Adam
    I work at a company that has many clients that have their own website that "plugs in" to our system. In other words they have their own website and they have a link that, when the user clicks it, transitions them over to our site. There is a feature that I want to track by giving the client a small block of code to put on their homepage. Whenever the homepage is loaded with a certain query string variable I want the block of code to request a file on my server. Then on the server I'll record the tracking info based on the query string. All this would be really easy if I can guarantee that the client would be using jQuery or some similar library, but there are a lot of clients and I can't really rely on them all using jQuery. At the same time I'd like to limit the size of the block of javascript code that they paste in. I think the best solution would be to have something like: if(querystring.substring("Tracking=") > 0) { include("blah.aspx?TrackingQS=" + querystring); } but I can't find a include function in built-in javascript without calling some library like jQuery. Any thoughts?? I could do straight up AJAX but I want to limit the number of lines of code for several reasons that I won't bore you with here.

  • std::locale breakage on MacOS 10.6 with LANG=en_US.UTF-8

    - by fixermark
    I have a C++ application that I am porting to MacOSX (specifically, 10.6). The app makes heavy use of the C++ standard library and boost. I recently observed some breakage in the app that I'm having difficulty understanding. Basically, the boost filesystem library throws a runtime exception when the program runs. With a bit of debugging and googling, I've reduced the offending call to the following minimal program: #include <locale> int main ( int argc, char *argv [] ) { std::locale::global(std::locale("")); return 0; } This program fails when I run this through g++ and execute the resulting program in an environment where LANG=en_US.UTF-8 is set (which on my computer is part of the default bash session when I create a new console window). Clearing the environment variable (setenv LANG=) allows the program to run without issues. But I'm surprised I'm seeing this breakage in the default configuration. My questions are: Is this expected behavior for this code on MacOS 10.6? What would a proper workaround be? I can't really re-write the function because the version of the boost libraries we are using executes this statement internally as part of the filesystem library. For completeness, I should point out that the program from which this code was synthesized crashes when launched via the 'open' command (or from the Finder) but not when Xcode runs the program in Debug mode. edit The error given by the above code on 10.6.1 is: $ ./locale terminate called after throwing an instance of 'std::runtime_error' what(): locale::facet::_S_create_c_locale name not valid Abort trap

  • Can I make any ASP.NET/HTML element into form-data that posts back to the server?

    - by Giffyguy
    I am using Javascript to alter the innerHTML attribute of a <td> and I need to get that info back in the form submittal. The <td> corrosponds to an <asp:TableCell> on the server-side, where the Text attribute is set to an initial value. The user cannot enter the value in this particular field. Instead, its value is set by me (via client-side script) based on actions that the user performs. But this field is useless to me if I can't see its value on the server-side as well. I'd like to avoid using a read-only textbox, because those are difficult to resize dynamically. Can an <asp:Label> be used as form data? Is there any way to achive this without letting the user manually enter the data? Or is there a simpler way to store a string as a variable somewhere and send it back as form-data?

  • phppgadmin : How does it kick users out of postgres, so it can db_drop?

    - by egarcia
    I've got one Posgresql database (I'm the owner) and I'd like to drop it and re-create it from a dump. Problem is, there're a couple applications (two websites, rails and perl) that access the db regularly. So I get a "database is being accessed by other users" error. I've read that one possibility is getting the pids of the processes involved and killing them individually. I'd like to do something cleaner, if possible. Phppgadmin seems to do what I want: I am able to drop schemas using its web interface, even when the websites are on, without getting errors. So I'm investigating how its code works. However, I'm no PHP expert. I'm trying to understand the phppgadmin code in order to see how it does it. I found out a line (257 in Schemas.php) where it says: $data->dropSchema(...) $data is a global variable and I could not find where it is defined. Any pointers would be greatly appreciated.

  • Temporary non-const istream reference in constructor (C++)

    - by Christopher Bruns
    It seems that a constructor that takes a non-const reference to an istream cannot be constructed with a temporary value in C++. #include <iostream> #include <sstream> using namespace std; class Bar { public: explicit Bar(std::istream& is) {} }; int main() { istringstream stream1("bar1"); Bar bar1(stream1); // OK on all platforms // compile error on linux, Mac gcc; OK on Windows MSVC Bar bar2(istringstream("bar2")); return 0; } This compiles fine with MSVC, but not with gcc. Using gcc I get a compile error: g++ test.cpp -o test test.cpp: In function ‘int main()’: test.cpp:18: error: no matching function for call to ‘Bar::Bar(std::istringstream)’ test.cpp:9: note: candidates are: Bar::Bar(std::istream&) test.cpp:7: note: Bar::Bar(const Bar&) Is there something philosophically wrong with the second way (bar2) of constructing a Bar object? It looks nicer to me, and does not require that stream1 variable that is only needed for a moment.

  • Jquery ajax auto complete problem

    - by squeaker
    Hi all, I'm having newbie problems resolving an ajax autocomplete script if anyone would like to offer advise? In my form i wish for users to select an event type (drop down box) which on selecting then displays a text box. This text box then offers a user the ability to autocomplete as they start typing, the options having been generated through AJAX depending on the event type selected. I'm using a mix of http://pengoworks.com/workshop/jquery/autocomplete.htm - to carry out the autocomplete and some basic jquery to identify the value of the event type selected. The problem I have within the code below is to pass the selected event type value, set as the variable 'caturl', into the 'extraParams:{cat:4}' replacing the 4 with the event type dynamically selected. Any help would be greatly received. $('#select').change(function() { $('.eventtype').hide(); $('#eventtype' + $(this).find('option:selected').attr('id')).show(); caturl = $('#select :selected').val(); }); $("#CityAjax").autocomplete( 'caturl.php', { delay:10, minChars:2, matchSubset:1, matchContains:1, cacheLength:10, onItemSelect:selectItem, onFindValue:findValue, formatItem:formatItem, extraParams:{cat:4}, autoFill:true });

  • Is it possible to use 2 versions of jQuery on the same page?

    - by Ben McCormack
    NOTE: I know similar questions have already been asked here and here, but I'm looking for additional clarification as to how to make this work. I'm adding functionality to an existing web site that is already using an older version of the jQuery library (1.1.3.1). I've been writing my added functionality against the newest version of the jQuery library (1.4.2). I've tested the website using only the newer version of jQuery and it breaks functionality, so now I'm looking at using both versions on the same page. How is this possible? What do I need to do in my code to specify that I'm using one version of jQuery instead of another? For example, I'll put <script> tags for both versions of jQuery in the header of my page, but what do I need to do so that I know for sure in my calling code that I'm calling one version of the library or another? Maybe something like this: //Put some code here to specify a variable that will be using the newer //version of jquery: var $NEW = jQuery.theNewestVersion(); //Now when I use $NEW, I'll know it's the newest version and won't //conflict with the older version. $NEW('#personName').text('Ben'); //And when I use the original $ in code, or simply 'jquery', I'll know //it's the older version. $('#personName').doSomethingWithTheOlderVersion();

  • Can't get data with spaces into the database from Ajax POST request

    - by J Jones
    I have a real simple form with a textbox and a button, and my goal is to have an asynchronous request (jQuery: $.ajax) send the text to the server (PHP/mysql a la Joomla) so that it can be added to a database table. Here's the javascript that is sending the data from the client: var value= $('#myvalue').val(); $.ajax( { type: "POST", url: "/administrator/index.php", data: { option: "com_mycomponent", task: "enterValue", thevalue: value, format: "raw"}, dataType: "text", success: reportSavedValue } ); The problem arises when the user enters text with a space in it. The $_POST variable that I receive has all the spaces stripped out, so that if the user enters "This string has spaces", the server gets the value "Thisstringhasspaces". I have been googling around, and have found lots of references that I need to use encodeURIComponent. So I have tried it, but now the value that I get from $_POST is "This20string20has20spaces". So it appears to be encoding it the way I would expect, only to have the percent signs stripped instead of the spaces, and leaving the hex numbers. I'm really confused. It seems that this sort of question is asked and answered everywhere on the web, and everywhere encodeURIComponent is hailed as the silver bullet. But apparently I'm fighting a different breed of lycanthrope. Does anyone have any suggestions?
