I do see two actions that might of use to you; however, they are called after the attachment has already been inserted/updated. <a href="http://grab.by/b2ew" rel="nofollow">http://grab.by/b2ew</a></p> <p>Using the "add_attachment" hook you could call your plugins custom functionality, post process the image and then "update" the attachment by sending the updated attachment object back to the wp_insert_attachment function. </p> https://legacy.forums.gravityhelp.com/topic/cant-hook-wp_insert_attachment#post-37192 Wed, 05 Oct 2011 20:59:52 +0000 kubante 37192@https://legacy.forums.gravityhelp.com/ <p>Hello,</p> <p>I am trying to hook the wp_insert_attachment function of wordpress,<br /> because I would like to preprocess the file upload from gravityforms.</p> <p>in the gravityforms function media_handle_upload I noticed the call to<br /> wp_insert_attachment like this:<br /> <pre><code>// Save the data $id = wp_insert_attachment($attachment, $file, $post_id); if ( !is_wp_error($id) ) { wp_update_attachment_metadata( $id, wp_generate_attachment_metadata( $id, $file ) ); }</code></pre> <p>I did the following in my plugin:<br /> <pre><code>public function __construct() { add_filter( &#39;wp_insert_attachment&#39;, array( $this, &#39;filter_insert&#39; ), 1, 3 ); }</code></pre> <p>and the filter_insert function looks like this:<br /> <pre><code>public function filter_insert( $attachment, $file, $id){ exit; }</code></pre> <p>The result is, that the filter_insert function is not called...</p> <p>best</p> <p>regards</p> <p>kubante </p>
