Flexible Upload D3Z Edition WordPress Plugin Not Working On WordPress 3.X

I have been using the Flexible Upload D3Z Edition WordPress plugin for a couple years now on various sites that I work on or manage. To me it provides a much easier interface to upload images while building thumbnails on the fly than the default WordPress image media upload. The issue is the Flexible Upload D3Z Edition plugin has not been updated since WordPress version 2.6.X so it has broken on more than one occasion. So when upgrading to WordPress 3 recently it broke the Flexible Upload D3Z Edition plugin and below I describe how to fix the plugin so it will operate without issue in WordPress 3.X.

Fix Flexible Upload D3Z Edition WordPress Plugin To Work With WordPress 3:

After investigating the issue I was able to locate the issue fairly quickly by determining that the plugin had been modified to only load with specific versions of WordPress. The modifications below allow the Flexible Upload D3Z Edition plugin to work with all versions of WordPress 3.X. I believe there were few changes with the wp-admin/media.php from WordPress 2.9 to WordPress 3.X so I basically just added a couple PHP if statements within the flexible-upload.php file to allow the plugin to load with WordPress 3.X. To make the modifications easier for others that want the Flexible Upload D3Z Edition WordPress plugin to work with WordPress 3 below I note the actual code added to the flexible-upload.php file followed by displaying the original flexible-upload.php file and then by displaying a completely modified flexible-upload.php file that can be inserted into the plugin’s directory to make Flexible Upload D3Z work with WordPress 3.

PHP Code Added To flexible-upload.php File For WP 3:

if (($fup_wpver[0] == 3) && ($fup_wpver[1] >= 0)) {
require_once(ABSPATH.$fup_rel_dir.'flexible-upload-wp26-fix.php');
}
if (($fup_wpver[0] == 3) && ($fup_wpver[1] < 0)) {
// When called in the plugin context, define the filter to use this
// script, instead of the existing inline-uploading.php script
function flexible_upload_iframe_src($frame_src) {
global $fup_rel_dir;
return str_replace('inline-uploading.php', get_bloginfo('wpurl')
.'/'.$fup_rel_dir.'flexible-upload-wp20.php',
$frame_src);
}
add_filter('uploading_iframe_src', 'flexible_upload_iframe_src');
}
else if (($fup_wpver[0] == 3) && ($fup_wpver[1] >= 0)) {
require_once(ABSPATH.$fup_rel_dir.'flexible-upload-wp25.php');
}

The two IF statements in the above code should be added at line 151 of the flexible-upload.php file and the ELSE IF should be added at line 173 of the flexible-upload.php file. Below I have listed the original flexible-upload.php file as well as the new flexible-upload.php file that will allow the Flexible Upload D3Z Edition WordPress plugin to work properly with WordPress 3.X. The flexible-upload.php file is located in the “wordpress-root/wp-content/plugins/flexible-upload/” directory. Before you begin any modifications to the flexible-upload.php file make sure that you backup the original first!

That should be the only modification you need to get the Flexible Upload D3Z Edition WP plugin working with WordPress 3. The below images display an example of what the Flexible Upload D3Z Edition plugin will look like when operating properly.

Some people will prefer the default image upload within WordPress including the Flash Upload or the Browser Upload however in my case I prefer the Flexible Upload D3Z Edition WordPress plugin.
