  • Bizarre error in php

    - by Satish
    I have a form in index.php <?php echo '<form action="update_act.php" method="POST">'; echo '<input type="submit" name="'.$row['act_name'].'" value="edit"> echo </form> ?> Here $row['act_name'] is a value fetched from database. My update_act.php file is <?php echo "Old Activity Name : ".$_POST['$row[\'act_name\']']; ?> But I am getting an error Undefined index: $row['act_name'] in C:\wamp\www\ps\activity\update_act.php. I want to have different names for different submits but I am not able to get its value in another page. Is there any way for it?

    - by 001
    How would I go about doing the following... I want to build a web service for my application to grab a piece of data from an external website, that requires the user to login.

Is there a library to perform the following functions? or what do I do? automate fill-in form, auto click Automate submit button check which URL the user has landed on, and redirect user to URL Grab data from label. EDIT: what im asking for is there a web service, library etc to make it easier to perform screen scrapping/automation functions???

  • What is the most efficient way to delete all selected items in a ListViewItem collection

    - by Andrew
    My user is able to select multiple items in a ListView collection that is configured to show details (that is, a list of rows). What I want to do is add a Delete button that will delete all of the selected items from the ListViewItem collection associated with the ListView. The collection of selected items is available in ListView.SelectedItems, but ListView.Items doesn't appear to have a single method that lets me delete the entire range. I have to iterate through the range and delete them one by one, which will potentially modify a collection I'm iterating over. Any hints? Edit: What I'm basically after is the opposite of AddRange().

  • Joomla! 2.5 use login data from another database

    - by user1756746
    I have a hard question. I'd like the joomla login does not use its own database for users/password but I want to use my database users with my table fields, my passwords etc.. I don't know from where start, I thought I could edit database request for login to my db or create a little script to automatically add the users on joomla database. I tried to see components/com_users/views/login/tmpl/default_login.php but it seems that there is nothing. Can someone help me figure out what to change? Maybe the simple thing is import my database users into database user joomla, is there any plugin or something else that you know? p.s. I use Clarion theme build on Gantry framework, Joomla! 2.5.6 Stable, PHP 5.2.17

  • in jqgrid, how can i have the editform disappear after submit

    - by leora
    right now, when i click submit it sends a message to the server and updates the databased and refreshes the screen but it keeps the edit form popup on the screen. Is there anyway to have it disappear once the submit is complete. its kind of annoying because its a little unclear that you are done because the form just sits there (even through the grid has refreshed) i have closeAfterEdit and closeAfterAdd set to true but it doesn't seem to do anything. jQuery("#grid").navGrid("#pager", { }, { height: 380, width: 500, reloadAfterSubmit: true, closeAfterEdit: true, url: siteRoot + controller + "/Update" }, { height: 380, width: 500, reloadAfterSubmit: true, closeAfterAdd: true, url: siteRoot + controller + "/Add" }, { reloadAfterSubmit: true, url: siteRoot + controller + "/Delete" }, { multipleSearch: true }

  • rails - form to disply non-input type fields in nested form

    - by nktokyo
    Hi, I guess this is a newbie question, but what is the syntax in a form to show contents of fields not as a text box/area, but rather like label would appear. <% form_for @user do |f| %> <% f.fields_for :user_ingreds do |builder| %> <p> <%= builder.??? %> </p> <% end %> <% end%> user has many user_ingreds and accepts_nested_attributes for user_ingreds. Basically I want to make a list of user_ingreds where the user can't edit the data but can remove the record from the list via a button - however the fields_for builder doesn't recognize a direct call to to the fields in user_ingreds model (ie, builder.user_id throws and error.

  • SVN - ignoring files already in repository

    - by Alex
    I have a configuration file in my project which needs to be in the repository (so new developers get it when they checkout the project). Each developer might change some values in the file locally - these changes should not be committed and I don't want them showing in the synchronization menu (I'm using eclipse and subversive if it matters). Note that I can't just set the svn:ignore property since it only works on files that aren't under version control - but I do want to keep a base version of the file in the repository. How can I avoid the file showing in synchronization without deleting it from repository? EDIT: A better description - what I actually need is to be able to set a "read-only" property on the config file, so it can't be changed in the repository as long as the property is on. Do you know anything like this? Thanks

  • Most efficient way to fetch and output Content with 2-Level Comments?

    - by awegawef
    I have some content with up to 2-levels of replies. I am wondering what the most efficient way to fetch and output the replies. I should note that I am planning on storing the comments with fields content_id and reply_to, where reply_to refers to which comment it is in reply to (if any). Any criticism on this design is welcome. In pseudo-code (ish), my first attempt would be: # in outputting content CONTENT_ID all_comments = fetch all comments where content_id == CONTENT_ID root_comments = filter all_comments with reply_to == None children_comments = filter all_comments with reply_to != None output_comments = list() for each root_comment children = filter children_comments, reply_to == root_comment.id output_coments.append( (root_comment, children) ) send output_comments to template Is this the best way to do this? Thanks in advance. Edit: On second thought, I'll want to preserve date-order on the comments, so I'll have to do this a bit differently, or at least just sort the comments afterward.

  • Best way to test instance methods without running __init__

    - by KenFar
    I've got a simple class that gets most of its arguments via init, which also runs a variety of private methods that do most of the work. Output is available either through access to object variables or public methods. Here's the problem - I'd like my unittest framework to directly call the private methods called by init with different data - without going through init. What's the best way to do this? So far, I've been refactoring these classes so that init does less and data is passed in separately. This makes testing easy, but I think the usability of the class suffers a little. EDIT: Example solution based on Ignacio's answer: import types class C(object): def __init__(self, number): new_number = self._foo(number) self._bar(new_number) def _foo(self, number): return number * 2 def _bar(self, number): print number * 10 #--- normal execution - should print 160: ------- MyC = C(8) #--- testing execution - should print 80 -------- MyC = object.__new__(C) MyC._bar(8)

  • Find java classes implementing an interface

    - by Linor
    Some time ago, I came across a piece of code, that used some piece of standard java functionality to locate the classes that implemented a given interface. I know the the functions were hidden in some non logical place, but they could be used for other classes as the package name implied. Back then I did not need it, so I forgot about it, but now I do, and I can't seem to find the functions again. Does anyone know where to find these functions? edit: I'm not looking for any IDE functions or anything, but rather something that can be executed within the java application.

  • Regular Expression issue

    - by Christian Sciberras
    I have the following URL structure which I need to match to and get the particular id from: /group/subgroup/id-name In short, I need to translate a URL like the following: /Blue Products/Dark Blue/5-Blue_Jelly To: /?pagename=Blue Products&model=5 IMPORTANT: I don't need to match group, I already have group. Example code: <?php foreach($cats as $cat) $cmd->rewrite('/\/'.$cat.'\/unused\/(ID)-unused\//','/?pagename='.$cat.'&model=%ID%'); ?> Edit: This is the completed code: if($groups->count()){ $names=array(); foreach($groups->rows as $row) $names[]=preg_quote($row->group); $names=implode('|',$names); $regex='('.$names.')/([^/]+)/([0-9]{1,})-([^/]+)/?$'; CmsHost::cms()->rewrite_url($regex,'index.php?pagename=Products',true); }

  • How to show the animation without exposing the code?

    - by bonCodigo
    There's an animation done in jQuery within jsfiddle. I do not have a website as of now to "implant" it and share the URL. I also can't give the jsfiddle. So how can I share my animation to the audience without showing the code? Does github or any other facility tools allow locking the code and showing the final product without having a website, yet I could get a URL for the audience to view it? I regret for the rookie-question in this context as I am still new to web stuff. EDIT: jsFiddle shows 3 code windows along the results :html, css, js. My requirement is to only show the results window to the audience and by all means to hide codes and leads via URL to the codes. Ideal solution demands a results to be shown and URL that is encrypted (at best).

  • Alternatives libraries for loading PNG images

    - by Robert
    My java J2SE application is reading a lot of (png) images from the web and some of them use features such as a transparency color for true-color images (tRNS section) that Sun's/Oracle's PNGImageReader implementation simply ignores. Therefore the common solution for loading via ImageIO.read(...); does not work for me as it relies on this incomplete PNGImageReader implementation. Does anybody know a png reader implementation that can read all forms of PNG images correctly - those with color table or true-color and alpha transparency or transparent color? As it is for a GPL project it should be a non-commercial one that can be included without licensing problems into the app. Edit: My be this question was too specific. Therefore let be redesign my question: Who knows alternative implementations and libraries that are able to load PNG files? I will then test the implementations for their capabilities to load some test png images. Edit2: The end result have to be a BufferedImage

  • Dynamic Column lookup with different pages in excel

    - by CinCity
    I have a multi page spread sheet in excel that needs to read information dynamically from columns on other pages and have these values show up on a main page. This is the formula I'm using: =IF(VLOOKUP($B:$B,'CP01'!$B:$BN,3,FALSE)="r","r", IF(VLOOKUP($B:$B,'CP01'!$B:$BN,3,FALSE)="a","a","")) CP01 is a sheet in the excel file and instead of look at the specific sheet I want it to look at all of the sheets in the file. Is there a way to do this as an excel formula or with excel-VBA? Edit: I also tried CP* (* being a wildcard character) and it didn't work. Edit2: Is there a way to match the value where the 'CP' is placed with its a other columns value?

Edit: let's say that I have the following structures: Reports table RepName primary key ReportData Users table ID primary key Name UserReports table RepName primary key UserID primary key IsDeleted now if I put isdeleted field in UserReports table, the user can't add same record again if it marked as deleted, because the record is already and this will make duplication.

  • Is it possible to make a PHP script run itself every hour or so without the use of a cronjob?

    - by Rob
    I'm pretty sure I've seen this done in a php script once, although I cant find the script. It was some script that would automatically check for updates to that script, and then replace itself if there was an update. I don't actually need all that, I just want to be able to make my PHP script automatically run every 30 minutes to an hour, but I'd like to do it without cronjobs, if its possible. Any suggestions? Or is it even possible? EDIT: After reading through a possible duplicate that RC linked to, I'd like to clarify. I'd like to do this completely without using resources outside of the PHP script. AKA no outside cronjobs that send a GET request. I'd also like to do it without keeping the script running constantly and sleeping for 30 minutes

  • Indexing affects only the WHERE clause?

    - by andre matos
    If I have something like: CREATE INDEX idx_myTable_field_x ON myTable USING btree (field_x); SELECT COUNT(field_x), field_x FROM myTable GROUP BY field_x ORDER BY field_x; Imagine myTable with around 500,000 rows and most of field_x values being unique. Since I don't use any WHERE clause, will the created index have any effect at all in my query? Edit: I'm asking this question because I don't get any relevant difference between query-times before and after creating the index; They always take about 8 seconds (which, of course is too much time!). Is this behaviour expected?

  • APC not recommended for production?

    - by solomongaby
    I have started having problems with my VPS in the way that it would faill to serve the pages on all the websites. It just showed a blank page, or offered to download the php file ( luckily the code was not in the download file :) ). The server was still running, but this seemed to be a problem with PHP, since i could login into WHM. If i did a apache restart, the sites would work again. After some talks with the server support they told me this is a problem with the APC extension witch they considered to be old and not recommended for production servers. So they removed it for now, to see if the same kind of fails would continue to appear. I haven't read anywhere that APC could have some problems or that its not always recommended to use, quite the contrary ... everywhere people are saying to always use it. The APC extension was installed ssh and is the latest version. Edit: They also dont recomend MemCache and say that a more reliable extension would be eAccelerator

  • ASP.net MVC support for URL's with hyphens

    - by John
    Is there an easy way to get the MvcRouteHandler to convert all hyphens in the action and controller sections of an incoming URL to underscores as hyphens are not supported in method or class names. This would be so that I could support such structures as sample.com/test-page/edit-details mapping to Action edit_details and Controller test_pagecontroller while continuing to use MapRoute method. I understand I can specify an action name attribute and support hyphens in controller names which out manually adding routes to achieve this however I am looking for an automated way so save errors when adding new controllers and actions.

  • Php code not executing - dies out when trying to refer to member of static class - no error displaye

    - by Ali
    I'm having some problems with this piece of code. I've included a class declaration and trying to create an object of that class but my code dies out. It doesn't seem to be an include issue as all the files are being included even the files called for inclusion within the class file itself. However the object is not created - I tried to put an echo statement in the __construct function but nothing it just doesn't run infact doesn't create the object and the code won't continue from there - plus no error is reported or displayed and I have error reporting set to E_ALL and display errors set to true WHats happening here :( =============EDIT SOrry I checked again the error is prior to teh object creation thing - it dies out when it tries to refer to a constant in a static class like so: $v = Zend_Oauth::REQUEST_SCHEME_HEADER; THis is the class or part of it - it has largely static functions its the Zend Oauth class: class Zend_Oauth { const REQUEST_SCHEME_HEADER = 'header'; const REQUEST_SCHEME_POSTBODY = 'postbody'; const REQUEST_SCHEME_QUERYSTRING = 'querystring'; // continued LIke I said no error is being reported at all :(
