• Deploy PHP website to client server without showing PHP files

  - by ColmF

  I asked a recent question regarding the use of readfile() for remotely executing PHP, but maybe I'd be better off setting out the problem to see if I'm thinking the wrong way about things, so here goes: I have a PHP website that requires users to login, includes lots of forms, database connections and makes use of $_SESSION variables to keep track of various things I have a potential client who would like to use the functionality of my website, but on their own server, controlled by them. They would probably want to restyle the website using content and CSS files local to their server, but that's a problem for later I don't want to show them my PHP code, since that's the value of what I'd be providing. I had thought to do this with calls to include() from the client's server to mine, which at least keeps variable scope intact, but many sites (and the PHP docs) seem to recommend readfile(), file_get_contents() or similar. Ideally I'd like to have a simple wrapper file on the client's server for each "real" one on my server. Any suggestions as to how I might accomplish what I need? Thanks, ColmF

• Populate javascript array with PHP array of Variables

  - by user1704514

  The following code is used to populate a pie chart in javascript: <script type="text/javascript"> var agg = { label: 'Aggressive', pct: [60, 10, 6, 30, 14, 10] }, bal = { label: 'Balanced', pct: [24, 7, 2, 18, 13, 36] }, mod = { label: 'Moderate', pct: [12, 4, 2, 10, 11, 61] }, inc = { label: 'Income', pct: [ 0, 0, 0, 0, 0,100] }, </script> Instead of tm: [40, 60, 67, 30, 74, 50] as seen above, I would like to make each of 6 values a php variable. Like: tm: [$r1, $r2, $r3, $r4, $r5, $r6] . How do I do this? How do I do this with? A php array or json encode?

• Doing a lot of input validation in VB.NET

  - by Andy

  I have a form set up where users can enter their booking for a room at my college. I want to validate the user input to avoid SQL injection (my program uses a MS Access database) and also stop numbers and synbols in their name, etc. I can do the validation fine, but there is to be a lot of validation and then methods executed only if all validation tests come back as true. I did have something like this: If txtName.Text = "" Then frmBookErr.SetError(txtName, "Name field cannot be left blank.") fail = 1 Else frmBookErr.SetError(txtName, "") fail = 0 End If And then check the fail variable, but it obviously gets overridden later in the form if one of the validation tests come back as true. Can anyone provide some input into this? Thanks.

• Which one is better to have auto-implemented property with private setter or private field and property just getter?

  - by PLB

  My question may be a part of an old topic - "properties vs fields". I have situation where variable is read-only for outside class but needs to modified inside a class. I can approach it in 2 ways: First: private Type m_Field; public Type MyProperty { get { return m_Field; } } Second: public Type MyProperty { get; private set; } After reading several articles (that mostly covered benefits of using public properties instead of public fields) I did not get idea if the second method has some advantage over the first one but writing less code. I am interested which one will be better practice to use in projects (and why) or it's just a personal choice. Maybe this question does not belong to SO so I apologize in advance.

• step attribute not working with HTML5 <input type="range"> on Safari

  - by Claudiu

  Are there known issues with range inputs not working fully on Safari? I have the following input element: <input type=?"range" min=?"0" max=?"360" step=?"0.0001" value=?"0">? On Chrome, the input goes according to the step variable. On Safari, it only goes by integer values. Even setting the step to 10 still makes it go by increments of 1. I'm confused because I thought Chrome and Safari both used WebKit.

  Hi, I need to write some data in several database. I choose sqlapi.com I have made it for mysql and mssql. Now I have Problem with Oracle database. I have installed server and client on Ubuntu. In browser it works, but sqlapi says: libnnz10.so: cannot open shared object file: No such file or directory DBMS API Library 'libclntsh.so' loading fails This library is a part of DBMS client installation, not SQLAPI++ Make sure DBMS client is installed and this required library is available for dynamic loading Linux/Unix: 1) The directories in the user's LD_LIBRARY_PATH environment variable 2) The list of libraries cached in /etc/ld.so.cache 3) /usr/lib, followed by /lib There are both of these files depp inside /usr/lib.

• How to evaluate text strings provided by sed/grep/whatever?

  - by T.J.

  This is for UNIX shell programming. It have to be supported by multiple UNIX platforms including Solaris, Linux, and AIX. I have this scenario -- I am to read from a text file a string that may or may not contain an environment variable that may or may not be defined. For example: <foo.bar> This error code was found: $(error_code) I have the following code: statement=$(sed -n $1'p' $messagefile) echo $echo_flag $statement $1 = line number supplied to this particular function/script. $messagefile = filename of log file. $echo_flag = "-e" in Linux, otherwise, empty. $(error_code) = 42. Instead of getting this when running: <foo.bar> This error code was found: 42 I still get this: <foo.bar> This error code was found: $(error_code) How exactly do I tell the shell script that the value of statement should be evaluated further beyond what sed have done?

• PHP error logging - can I log all ofg the site's error to a single file?

  - by mawg

  hi, in PHP.INI, I can set the variable "error_log" and it is currently set to "error_log", which manes one file of that name in each directory Do you know ... if I set it to "public_html/error_log" - will I get only one single error log file? Any other way to do so? I really just want a single site-wide error file to check, rather than one on each sub-directory. For bonus marks, can I send myself an email each time a new entry is added to the file? Left as an exercise for the reader - can I ignore some "errors" which aren't really?

• IDisposable, does it really matter

  - by adrianm

  Coming from C/C++ a long time ago I still have a habit of ensuring that all resources are cleaned up correctly. I always ensure Dispose is called on IDisposable classes and implement Dispose patterns in my classes containing disposable objects. However, in my environment I'm more or less the only one doing this. Others just don't understand what I'm doing and think my code is more difficult to understand. They just create database connections, open streams etc without calling Close or Dispose. Sometimes they set a local or member variable to "Nothing" at the end of a method (guess their background). My problem is that their code works just as well as mine. Code that over time creates thousands of database connection objects just works. So, ignoring any arguments about code correctness, following guidelines etc, does IDiposable really matter? Has anyone actually ran out of resources from not Disposing objects?

• Add columnname and data from datatable to a dictionary? C#

  - by Nick

  Hi, I am looping through a datatable and currently I do string customerId = row["CustomerId"].ToString(); string companyName = row["Company Name"].ToString(); Instead of declaring every variable how do I add these do a dictionary? I was thinking something like: foreach (DataRow row in customerTbl.Rows) { Dictionary<string, string> customerDictionary = new Dictionary<string, string>(); customerDictionary.Add(row[].ToString(), row[].ToString()); so yeah, how do I get the row name and value into there? Thanks in advance.

• [MAC] Using a proxy for NSURLConnection

  - by SideSwipe

  Is there any way to get the content of a webfile (namely a .html Document) using a proxy, which is not defined in the system settings? I know that NSURLConnection is the right way to download a web file into a variable and not into a file (for which we should use NSURLDownload), but I don't find an way to use a proxy for it. Are there some inofficial APIs, Librarys or Classes or such I could use for what I want to do? I'm not that pro in Mac Programming, so im searching for something more or less simple to do for me plz.

• How can I implement a login wall for expired or inappropriate pages?

  - by Redandwhite

  I am writing a website that very explicitly requires a login wall. Visitors should be required to log in before they are allowed to view a page. The page being built depends very much on the user's "ID". I am not sure how or where to store the user's login. I am not sure whether I should use a session variable (e.g. Session["userId"]), or some other method. The problem I see with session variables is that it's difficult to time out sessions. Note: I'm using C# 3.5 with ASP.NET in Visual Studio 2008.

• const ready only local copies

  - by robUK

  Hello gcc 4.4.4 c89 I am just wondering is it worth passing a const into a function. i.e. void do_something(const char *dest, const int size) The size is a ready-only so I don't want to change it. However, some developers never have this as const has it is a local copy that is being used. The pointer is const as you can change the value in the calling routine. I always have a const on ready-only local copies, as it confirms to anyone reading my code that it is a ready-only variable. And also, when coding I don't make the mistake of changing it without realizing. Many thanks for any suggestions,

• Why did I get a 400 Bad Request when getting a page with PHP Curl?

  - by user307272

  Hi, I was trying to access a page using curl. I could access it perfectly using the browser and using "static" strings as the URL, like: $url = "http://www.example.com/?q=1234" But when I tried to access the page using a variable in the URL string like: $url = "http://www.example.com/?q=$param" I got a 400 error code. I checked out on the web and found some comments here in this stackoverflow thread: Then, just for curiosity I did the following: $url = "http://www.example.com/?q=" . trim($param); and it worked! And no, $param did NOT contain any spaces. To me, it seems that it can be some encoding error, but I really can't find an explanation for it. Does anyone here in stackoverflow know what it can possibly be? Thanks in advance :)

• what's called after returning from presentModalViewController / dismissModalViewControllerAnimated:

  - by Reinhard

  to show a modal uiview out of my mainView I use: [self presentModalViewController:myController animated:YES]; and in MyController I close that view with: [self dismissModalViewControllerAnimated:YES]; But how can I know in the mainView that the modal was finished (to redraw my table)? Currently I set a local variable to YES in my mainView after starting the modal view an react on viewWillAppear: [self presentModalViewController:myController animated:YES]; _reloadTableData = YES; -(void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; if (_reloadTableData) { _reloadTableData = NO; [_tableView reloadData]; } } Is there a better way to do so ?

• Why do they initialize pointers this way?

  - by Rob

  In almost all of the books I read and examples I go through I see pointers initialized this way. Say that I have a class variable NSString *myString that I want to initialize. I will almost always see that done this way: -(id)init { if (self = [super init]) { NSString *tempString = [[NSString alloc] init]; myString = tempString; [tempString release]; } return self; } Why can't I just do the following? -(id)init { if (self = [super init]) { myString = [[NSString alloc] init]; } return self; } I don't see why the extra tempString is ever needed in the first place, but I could be missing something here with memory management. Is the way I want to do things acceptable or will it cause some kind of leak? I have read the Memory Management Guide on developer.apple.com and unless I am just missing something, I don't see the difference.

• Looking at the C++ new[] cookie. How portable is this code?

  - by carleeto

  I came up with this as a quick solution to a debugging problem - I have the pointer variable and its type, I know it points to an array of objects allocated on the heap, but I don't know how many. So I wrote this function to look at the cookie that stores the number of bytes when memory is allocated on the heap. template< typename T > int num_allocated_items( T *p ) { return *((int*)p-4)/sizeof(T); } //test #include <iostream> int main( int argc, char *argv[] ) { using std::cout; using std::endl; typedef long double testtype; testtype *p = new testtype[ 45 ]; //prints 45 std::cout<<"num allocated = "<<num_allocated_items<testtype>(p)<<std::endl; delete[] p; return 0; } I'd like to know just how portable this code is.

• it is possible to "group by" without losing the original rows?

  - by toPeerOrNotToPeer

  i have a query like this: ID | name | commentsCount 1 | mysql for dummies | 33 2 | mysql beginners guide | 22 SELECT ..., commentsCount // will return 33 for first row, 22 for second one FROM mycontents WHERE name LIKE "%mysql%" also i want to know the total of comments, of all rows: SELECT ..., SUM(commentsCount) AS commentsCountAggregate // should return 55 FROM mycontents WHERE name LIKE "%mysql%" but this one obviously returns a single row with the total. now i want to merge these two queries in one single only, because my actual query is very heavy to execute (it uses boolean full text search, substring offset search, and sadly lot more), then i don't want to execute it twice is there a way to get the total of comments without making the SELECT twice? !! custom functions are welcome !! also variable usage is welcome, i never used them...

• Finding the most similar numbers across multiple lists in Python

  - by new_sysadmin

  In Python, I have 3 lists of floating-point numbers (angles), in the range 0-360, and the lists are not the same length. I need to find the triplet (with 1 number from each list) in which the numbers are the closest. (It's highly unlikely that any of the numbers will be identical, since this is real-world data.) I was thinking of using a simple lowest-standard-deviation method to measure agreement, but I'm not sure of a good way to implement this. I could loop through each list, comparing the standard deviation of every possible combination using nested for loops, and have a temporary variable save the indices of the triplet that agrees the best, but I was wondering if anyone had a better or more elegant way to do something like this. Thanks!

• What should I name instances of a twisted.internet.defer.Deferred?

  - by slacy

  I'm writing code using Twisted, and having trouble coming up with a sensible variable name for my twisted internet deferred's. Here are my candidates: d : Too generic, too short, violates pylint rule C0103. def : Conflicts with function defintion builtin. defer : Conflicts with module twisted.internet.defer deferred : OK but pretty long cb : Still too short, violates pylint C0103, conflicts with many callback method names. cback : Too Weird? callback : Conflicts with method Deferred.callback() I'm looking for other suggestions. It seems like most of the Twisted example code uses "d" which is fine for simple invocations, but when you're passing Deferred's around to methods and storing them as member variables, it's really far too descriptive.

• std::out_of_range error?

  I'm dealing with a file with a linked list of lines with each node looking like this: struct TextLine{ //The actual text string text; //The line number of the document int line_num; //A pointer to the next line TextLine * next; }; and I'm writing a function that adds spaces at the beginning of the lines found in the variable text, by calling functions like linelist_ptr->text.insert(0,1,'\t'); The program compiles, but when I run it I get this error: terminate called after throwing an instance of 'std::out_of_range' what(): basic_string::at Aborted Any ideas?
