and will be sent by email on the address you specify into the Contact forms settings. (By default it will be the admin email).

[Advanced] Hooks

The Udesly App WordPress plugin allows you to further modify the contact forms behaviours using hooks.

Actions

Action Hooks allow you to insert custom code at various points (wherever the hook is run).

Before form sent

Fired before form get’s saved to database/sent by email.

do_action('udesly/ajax/contact/before_form_sent', array $form_data)

Parameters

  • $form_data: associative array containing the data sent by the form, e.g: $form_data['email'] is the field with the name email;

This action can be used for example to prevent a form to be sent in certain conditions: (for example, an user not logged in, or a form data is invalid and so on!)

The example below prevents the usage of forms for not logged in users. Since it’s an ajax call, to stop execution of the process, you just need to use wp_send_json_error or wp_send_json_success, both functions automatically call wp_die function.

function mytheme_disable_forms_for_not_loggedin_users($form_data) {
    if (!is_user_logged_in()) {
        wp_send_json_error("Only logged in users can send forms!");
    }
}

add_action('udesly/ajax/contact/before_form_sent', 'mytheme_disable_forms_for_not_loggedin_users' );

After form Sent

Fired after a form get’s saved to database/sent to email.

do_action('udesly/ajax/contact/after_form_sent', array $form_data)

Parameters

  • $form_data: associative array containing the data sent by the form, e.g: $form_data['email'] is the field with the name email;

This action can be used for example to log a form data into a file or to send it to a third party API and so on.

function mytheme_save_to_debug_log($form_data) {
    error_log( var_export( $form_data, true ) );
}

add_action('udesly/ajax/contact/before_form_sent', 'mytheme_save_to_debug_log' );

Filters

Filter Hooks allow you to manipulate and return a variable.

Do never forget to return the variable you are going to modify with the filter! Or your server will die ☠️
