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’);
For wp_insert_attachment and wp_generate_attachment_metadata, change $file_name in the following way. $file_name = $upload_dir[‘path’] . “https://wordpress.stackexchange.com/” . basename($file_name); WordPress codex for both function ( here and here ) says- ‘ Use absolute path and not the URI of the file. The file MUST be on the uploads directory’ $_FILES[‘fileUpload’] just gives the name of the file … Read more
You just need to add post_type argument like this: $wp_query = new WP_Query( array( ‘s’ => $_GET[‘s’], ‘post_type’ => array( ‘post’, /* add more post types if need be */ ), ) ); Read the codex article about WP_Query class for more information.
Advanced Custom Fields is a great solution – allows you to attach anything to your pages/posts/custom post types, great interface for setting it up, and very flexible. Good documentation as well.
At some point in the process you could do the following: Generate attachment ID from URL, like here Save attachment ID to custom field value using add_post_meta() Retrieve attachment using custom field value later with get_post_meta()
wp_insert_attachment returns the resulting post_ID of attachment record created in posts table, so you will need to add these IDs (multiple) in the post meta table using update_post_meta as suggested in code below: $attchmentIds = array(); if ($_FILES) { foreach ($_FILES as $file => $array) { $newupload = insert_attachment($file,$pid); $attchmentIds[] = $newupload; } }; /*The … Read more
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
There’s no way of doing this without “listening” for the responsible database query and altering it with the query filter, thanks to this line in wp_delete_post(): // Point all attachments to this post up one level $wpdb->update( $wpdb->posts, $parent_data, $parent_where + array( ‘post_type’ => ‘attachment’ ) ); The following will override the query and set … Read more
