I want to create a form on a page but how do I handle the form submission.

Which hook should i implement to handle my submission? Probably dirtiest would be to do it in the theme itself but I don't want it that way... probably not the right way to do it

  • Are you just doing a contact form submission? What is the forms purpose? You handle forms in WordPress just like you would any other normal form - $_GET and $_POST. – Howdy_McGee Apr 17 '14 at 20:11
  • @bigant841 Are you talking about a custom form or are would you like to use a plugin form? – Howdy_McGee Apr 17 '14 at 20:12
  • it's a form that will create posts, comments with my plugin. – yeahman Apr 17 '14 at 20:27

I would use init hook in your plugin file to register custom function

add_action( 'init', 'custom_proccess_form' );

And then check form inputs in the custom function, you mentioned creating posts

function custom_proccess_form() {

    $wp_error = true;   // report errors or not
    $nonce = $_POST['_wpnonce'];

    if( isset($_POST['insert_post']) && wp_verify_nonce($nonce, 'my-nonce-name') ) {

        $post = array(
            'post_title' => $_POST['new_post_title'],
            'post_content' => $_POST['new_post_content'],
            );

        // form actions
        $post_id = wp_insert_post( $post, $wp_error );

        // now you can use $post_id within add_post_meta or update_post_meta

        // redirect at the end to some url
        wp_redirect('/?success=true');
    }
}

The form itself could look like this

<form method="POST">
    <?php wp_nonce_field('my-nonce-name'); ?>
    <input type="text" name="new_post_title">
    <textarea name="new_post_content"></textarea>
    <input type="hidden" name="insert_post" value="1">
    <button type="submit">Submit!</button>
</form>
  • ok looks neat. Is there functions for flash messages? (session message that are displayed and auto erased on redirection) – yeahman Apr 18 '14 at 16:13
  • what is $wp_error used for? – yeahman Apr 18 '14 at 17:32
  • optional parameter for WP error, good for testing, see codex.wordpress.org/Function_Reference/wp_insert_post – rozklad Apr 19 '14 at 8:50

    i dont use bbpress, but maybe you could lower the priority of the action by specifying something like add_action( 'init', 'custom_proccess_form', 100 ); – rozklad Apr 19 '14 at 9:38
