The action sends the $post_id just like you have so that’s not the problem. Have you tried a var_dump of $_POST to make sure it’s actually posting something other than null? Also, using the save_post action is going to be called every time a post is saved, so you probably need to use the save_post_{custom_post_type} … Read more
You can strip images on display pretty easily. add_filter( ‘comment_text’, function($comment) { $allowed_html = array( ‘a’ => array( ‘href’ => array(), ‘title’ => array() ), ‘br’ => array(), ’em’ => array(), ‘strong’ => array() ); return wp_kses($comment, $allowed_html); } ); That will strip any tags not listed in the provided array. To specifically strip images … Read more
I’ve just had this or a very similar problem (I didn’t use the WP export tool, but instead did a manual migration from one environment to another). As far as I can tell, the problem occurs because of how WP stores the thumbnail data in the the wp_postmeta table (with the key ‘_wp_attachment_metadata’). This data … Read more
As things like this are often requested, I’ve written a plugin named “Dynamic Image Resize”. It’s basically a plugin, but, due to it’s one-file approach, it can be used as mu-plugin or theme include without a problem. It’s main purpose is to resize single images on demand to a given height/width. These are the arguments … Read more
I’m not quite sure you’re using the wp_check_filetype() correctly. I just successfully tried the following to determine if the post thumbnail ext was jpg or not: $url = wp_get_attachment_url( get_post_thumbnail_id( ) ); $filetype = wp_check_filetype($url); if ($filetype[ext] == ‘jpg’) { echo ‘this is gif’; } else { echo ‘this aint gif’; } You probably know … Read more
As a rule, I suggest you try to stick as much as possible to WordPress core functions when modifying the database, as they will handle associated data automatically – e.g. delete associated post meta, associated taxonomy info, etc. (Woocommerce stores product image data as product post_meta, see below for details.) This might slow things down … Read more
Here is another possibility, it alters the image markup when you select an image to add to your content in the editor add_filter( ‘image_send_to_editor’, ‘remove_img_attribute’, 10, 8 ); function remove_img_attribute( $html, $id, $caption, $title, $align, $url, $size, $alt ) { $imagetpl=”<figure> <a href=”https://wordpress.stackexchange.com/questions/129666/%s” title=”https://wordpress.stackexchange.com/questions/129666/%s”><img src=”https://wordpress.stackexchange.com/questions/129666/%s” alt=”https://wordpress.stackexchange.com/questions/129666/%s” class=”img-responsive %s” /></a> %s </figure>”; $figcaption = (!empty($caption)) ? … Read more
This can be done with two filters, attachment_fields_to_edit and attachment_fields_to_save, which do exactly what their names suggest. Let’s say you wan to add a source field. First, generate the field and fill it with its current value if that exists: function wpse133608_add_attachment_location_field( $form_fields, $post ) { $field_value = get_post_meta( $post->ID, ‘source’, true ); $form_fields[‘source’] = … Read more
I highly recommend updating all of your URLS. This can be done either with a word press plugin such as Velet Blues Update URLS Or via your SQL database: UPDATE wp_posts set post_content=REPLACE(post_content, ‘www.live.com/’, ‘www.test.com/’); note* images are uploadeded as posts in your database.* ( wp_posts table with a post_type of “attachment”. )
Find the actual large version of the image file (i.e., wp-content/uploads/2014/03/my-image-1024×576.jpg) and see if in fact it has the smaller dimensions or if it is just being rendered that way in your theme. If the large version is in fact 1024px wide, then the filter is working. Make sure you are referencing the right image … Read more
