use php’s implode to join array elements with a string: <?php if( $bands = get_post_meta($post->ID, ‘band’) ): ?> <strong>Band:</strong> <?php echo implode( $bands, ‘, ‘ ); ?><br /> <?php endif; ?> EDIT- another version of above, pluralizing the label depending on single or multiple meta values: <?php if( $bands = get_post_meta($post->ID, ‘band’) ): $label = … Read more
The solution is to use wp_get_attachment_image_src. As per the Codex: $attachment_id = 8; $size=”full”; // returns an array $image_attributes = wp_get_attachment_image_src( $attachment_id, $size ); Although the return is said to be: [0] => url [1] => width [2] => height There is a fourth element that indicates if it is the full image (false) or … Read more
Ok, so I don’t know what I was doing wrong because I tried this before and couldn’t get it to work but I ended up using array_values() after a couple of people recommended it in another thread. I finally ended up writing it like this: get_terms( array_values((get_taxonomies(”,’names’))) , $args );
There is already a function in WordPress doing that: wp_terms_checklist(). It is used in the metabox for hierarchical taxonomies in the post editor. Maybe you can reuse that? The following is untested, see it just as a guide please, not as a complete solution: // File where “wp_terms_checklist()” is declared require_once ABSPATH . ‘wp-admin/includes/template.php’; // … Read more
Don’t use update_usermeta, it is deprecated, update_user_meta is the one to use. You get the previously saved value out with get_user_meta. <input type=”text” name=”group[]” id=’group[]’ class=”regular-text” value=”<?php echo esc_attr( get_user_meta( $user->ID, ‘group’, true ) ); ?>” />
get_the_tags() returns an array but the indexes do not start at 0 because they are the term ids.
You need to specify a list of allowed mime types. You could make it easy by just getting the allowed mime types like: $file = $_FILES[‘the-file’]; $upload_file = wp_handle_upload($file, array( ‘test_form’ => false, ‘mimes’ => get_allowed_mime_types() )); If you look at the codex for Default allowed mime types, you could manually specify which ever mime … Read more
I normalize the output of these functions using this logic: Cast the value to an array. If it is not an array already, it will be converted to an array with one element, which is the value it was, e.g. (array) false becomes array (false). Use array_filter, which, when not passed a callable, simply filters … Read more
This happens, because WP checks the value with empty(): if ( ! empty( $value ) ) … and empty() is TRUE for values like 0 or “0”. You have two options now: Filter walker_nav_menu_start_el and replace <a with <a tabindex=0. Pass $atts[‘tabindex’] = “0 “; in your original function. Note the extra space. It circumvents … Read more
This is not really a WordPress question but more PHP. To solve this problem, you need to use $value as your key as well plus _id You can do something like this $options[$value . ‘_id’] = ot_get_option($value); EDIT If you need $key to be the value of id, you can also try something like this … Read more
