This is what you’re looking for: http://codex.wordpress.org/Plugin_API/Action_Reference/init Example from Codex: add_action(‘init’, ‘process_post’); function process_post(){ if(isset($_POST[‘unique_hidden_field’])) { // process $_POST data here } }
If you are working on a custom theme, I believe it is easier to be done with a page template and WordPress’s wp_ajax function. The form can be included in the page using <?php get_template_part(‘form’,’0f-50-question’) ?>. Here is the pseudo code for the form <form id=”quite-a-long-form” action=”<?php echo admin_url(‘admin-ajax.php’); ?>” method=”post” class=”form” > $step = … Read more

You can change a bunch in one hit with the gform_address_types filter, like this: /** * customise the Address field labels * @param array $addressTypes * @return array */ add_filter(‘gform_address_types’, function ($addressTypes) { $addressTypes[‘international’][‘zip_label’] = ‘Postcode’; $addressTypes[‘international’][‘state_label’] = ‘State’; return $addressTypes; });
With saving child terms, I believe you can add them to the $term_array group where the parent lives. From the perspective of a post (or custom post type) saving the taxonomy has nothing to do with parent or child. The WP Codex states “For hierarchical terms (such as categories), you must always pass the id … Read more
If you were looking to make the fields required in the WordPress admin form for adding new user as i understood from your question, where the output is not filterable, you could basically do what you described (adding form-required) on browser side function se372358_add_required_to_first_name_last_name(string $type) { if ( ‘add-new-user’ === $type ) { ?> <script … Read more
No, but you can just run stripslashes on it.
You need to pull your meta_data from WP and fill that info into the form… like so: function my_form_function() { global $current_user; $low_price = get_user_meta( $current_user->ID, ‘_low_price’, true); $medium_price = get_user_meta( $current_user->ID, ‘_medium_price’, true); $high_price = get_user_meta( $current_user->ID, ‘_high_price’, true); ?> <form name=”setPrices” action=”” method=”POST”> <fieldset> <label for=”lowPrice”>Value 3:</label> <input type=”text” id=”lowPrice” name=”lowPrice” value=”<?php echo … Read more
So I came back to this after practice and implemented some of the Alchemy setup, meaning all the inputs have names like name=”_movies[3]Metabox repeating fields – radio buttons not saving correctly” where 3 is the iteration we’re on in the loop. Create the Metabox // metaboxes should be registered on the add_meta_boxes hook add_action(‘add_meta_boxes’, ‘add_meta_boxes’ … Read more
Without Ajax or plugins. Add to function.php: add_action( ‘set_comment_cookies’, function( $comment, $user ) { setcookie( ‘ta_comment_wait_approval’, ‘1’ ); }, 10, 2 ); add_action( ‘init’, function() { if( $_COOKIE[‘ta_comment_wait_approval’] === ‘1’ ) { setcookie( ‘ta_comment_wait_approval’, null, time() – 3600, “https://wordpress.stackexchange.com/” ); add_action( ‘comment_form_before’, function() { echo “<p id=’wait_approval’ style=”padding-top: 40px;”><strong>Your comment has been sent successfully.</strong></p>”; }); … Read more
