I am relatively new to WordPress and have never coded a plugin. I thought that this would be a great place to get my feet wet. :)
I am working to update the "NextGEN Gallery Search" plugin (http://wordpress.org/plugins/nextgen-gallery-search/) that appears to have been abandoned since it has not been updated in over 2 years and the authors website is gone. It allows you to find the gallery you are looking for without browsing all the admin galleries pages.
NextGen Gallery 2.0 is currently in beta and this plugin doesn't work any longer. I rely on the functionality of this plugin, so I have corrected most everything. I am getting stuck with the search portion of it.
The plugin has the following code
<form method="post" action="<?=$_SERVER['REQUEST_URI']?>"> <table class="form-table" style="width:570px;"> <tr valign="top"> <th scope="row"><label for="ngs2_filter">Search Keyword</label></th> <td><input name="ngs2_filter" type="text" id="ngs2_filter" value="<?=$_POST['ngs2_filter'];?>" class="regular-text" /></td> <td><input type="submit" name="Submit" class="button-primary" value="Search" /></td> </tr> </table> </form> $gallerylist = ngs2_search_galleries($_POST['ngs2_filter']);
With the code above, when you visit the admin page
<?=$_POST['ngs2_filter'];?> appears in the search box. If you attempt a search, you receive a "404 Not found" with the address bar showing "192.168.0.105/wp-admin/<?=$_SERVER['REQUEST_URI']?>"
I have attempted to follow the WordPress Codex (http://codex.wordpress.org/Function_Reference/get_search_form), but it doesn't explain the various varialbe the plugin seems to use.
Can someone please advise me on what might be the issue with the above code or point me in the direction of information that will further explain how to fix this?
I am unable to post a link as it is on a dev server without inbound service.
The function works correctly on WordPress version 3.5.2 and current version 1.9.13 of Nextgen Gallery.
Thanks so much in advance
