Unfortunately, this is not possible, at least not safe. The function wp_insert_term( $term, $taxonomy, $args = array() ) that handles the creation of taxonomies provides a few filters and hooks, but the only one before the creation of the term in the database is $term = apply_filters( ‘pre_insert_term’, $term, $taxonomy ); As you can see, … Read more
I typically use CSS and jQuery for this type of thing by hooking admin_head. This should be done client-site as a user has an option to select your template or another one after DOM load. Basically, all you do is check if the value is set for #page_template and toggle show/hide if your template is … Read more
Short version — there isn’t one. WordPress doesn’t handle dependencies logic in any form. If library itself doesn’t include any mechanism for it (which is exceedingly rare) — there isn’t anything you can do. At best you can (and should) check if expected version of dependency is loaded (if it exposes version in some form … Read more
To help you understanding how forms work: They add to the $_POST array by a form fields name argument. <input type=”text” name=”foo” value=”Fooo!” /> would produce $_POST (array) => foo => Fooo! while <input type=”text” name=”foo[bar]” value=”Bar.” /> <input type=”text” name=”foo[baz]” value=”Baz.” /> would produce $_POST (array) => foo => (array) => bar => Bar. … Read more
First, let me say that there is no web application 100% secure. That being said, you are using the nonce correctly. The function you are using, update_post_meta(), will sql-scape the data as it uses insert/update methods of wpdb class. So, there is no risk for most common security problemas. What you should take care, I … Read more
I’d recommend using the template_include filter as opposed to template_redirect, as using this hook means that you don’t redirect the user but rather just present them with the template that is requierd. add_filter(‘template_include’, ‘my_custom_template_redirect’, 99); function my_custom_template_redirect($template){ global $post; if(is_single() && ‘campaign’ == get_post_type($post)){ $page_template = get_page_template(); $new_template = locate_template( array( ‘subfolder/’ . $page_template . … Read more
You are wrong, your custom field is saved but you won’t see the value pre-selected in the select box. To see it you have to set the selected attribute of the select element. You can do it easily with selected() function. You should also escape the attribute values and, in your case, use wp_reset_postdata instead … Read more
You hook the tr_change_show_title to a filter inside the function itself, that can make a infinite loop. All the stuff removing/adding actions and filters inside the functions should be deleted; instead check if the post data should be updated or not. In your case you should check if the title has the value you desire … Read more
Does this do the trick? $consignment= get_post_meta($post->ID, ‘availability’, true); if ($consignment == ”) { // code to run if the above is empty, eg. echo “avaliable”; } else { // else the code, eg. echo $consignment; }
$change = get_post_meta($post->ID, $key, ‘resume_change_location’, true); From https://developer.wordpress.org/reference/functions/get_post_meta/ get_post_meta returns an array, not an object so you need to use $change[‘index’] The other thing is within your meta box you seem to be saving a string not an array so foreach is going to fail. The below should work… $change = get_post_meta( $post->ID, $key, ‘resume_change_location’, … Read more
