You could use substr() Returns the portion of string specified by the start and length parameters. in combination with strrpos() Find the numeric position of the last occurrence of needle in the haystack string. Example $name = basename( wp_get_attachment_url( $post->ID ) ); echo substr( $name, 0, strrpos( $name, ‘.’ ) ); This will show the … Read more
I solved it. The problem was, that I called the function inside of another function, called later. The snippet in the question works like it should. I thought about deleting the question, but I think for other users, that are searching for a way to do something like that, the snippet would be interesting.
With markup embedded into the content there is no less tricky way than regex to do it, save perhaps a markup parser like SimpleHTMLDom function remove_image_link_102512($content) { $pattern = ‘|<a.*?href=”https://wordpress.stackexchange.com/questions/102512/(.*)”.*>?(<img.*?/?>)(?:</a>)?|’; $content = preg_replace($pattern,’$2′,$content); return $content; } add_filter(‘the_content’,’remove_image_link_102512′); As with all regex + markup solutions, I’d test that thoroughly. Of course, as no saved data is … Read more
If $att is a numeric post ID, then try this: $attachment = get_post( $att ); echo( $attachment->post_excerpt ); has_excerpt() takes a post ID, but the post ID isn’t an object. You have to get the attachment using get_post(), then get the excerpt from there.
If this is a regular custom field, use get_post_meta(): $classes = get_post_meta( $attachment_id, ‘name_of_the_field’, TRUE ); attachment is just another post type, regarding to meta data, it works like regular posts or pages.
Just use a custom $wpdb query, something like function remove_all_attachments() { global $wpdb; $ids = $wpdb->get_col(“SELECT ID FROM $wpdb->posts WHERE post_type=”attachment””); if ( empty($ids) ) return; $remove = implode(‘,’, $ids); // remove post meta $wpdb->query(“DELETE FROM $wpdb->postmeta WHERE post_id IN ({$remove})”); // remove posts $wpdb->query(“DELETE FROM $wpdb->posts WHERE ID = IN ({$remove})”); } After that … Read more
That’s not going to work, instead just use wp_get_attachment_image_src , it takes a size parameter. // get the $attachment_id $attach_stuff = wp_get_attachment_image_src( $attachment_id, ‘full’); var_dump($attach_stuff); You will be returned an array fo values to work with: [0] => url [1] => width [2] => height [3] => boolean: true if $url is a resized image, … Read more
When you upload a media from a post, the post_parent attribute is setted to the post ID you are uploading from. Not so when you simple insert a post from the library: in that case if the media was already attached to a post, its post_parent is already setted, and once a media can have … Read more
If u want to just change the upload directory you can use something like this: function wp128084_upload_dir( $pathdata ) { // change path here return $pathdata; } add_filter(‘upload_dir’, ‘wp128084_upload_dir’); and again to remove this you can use this remove_filter(‘upload_dir’, ‘wp128084_upload_dir’);
In PHP function can return it’s value only one time. After returning value, function dies. If you want to return multiple values, you have to use array. So your code could look like this: function get_images() { global $post; // you don’t use $post in your code, so it’s redundant $size=”medium”; $attachments = get_children( array( … Read more
