    'form_title' => 'Simple contact form',
    'submit_label' => __('Send', 'text_domain')
    'fields' => [
        [

            'placeholder' => 'sven.svensson@company.com',
        ],
        [
            'type' => 'textarea',
            'name' => 'message',
            'label' => 'Message',
            'placeholder' => 'Hello! I have a question about...',
        ],
        [
            'type' => 'checkbox',
            'name' => 'gdpr',
            'label' => 'I agree to the following <a href="google.se">terms</a>',
            'required' => true,
        ]
    ]
]);

Filters and Actions

There is a few filters and actions available for you to customize som things

Messages

Example for customizing messages

function theme_custom_qterest_messages($messages, $params) {

    $messages['success'] = __("Thank you! We will contact you as soon as possible!", 'text_domain');

    return $messages;

}
add_filter('qterest_contact_messages', 'theme_custom_qterest_messages', 10, 2);

The following messages can be changed

• name_empty
• email_empty
• email_invalid
• failed
• success
• mail_subject
• mail_body
• mail_to

Form submission data can be accessed through the $params parameter

Filter to remove attachments after request

You can use the following filter to remove attachments after a request

function theme_remove_attachment_after_request($remove, $params, $post_id) {
    // You may access $params or $post_id if you wish to remove attachments conditionally
    $remove = true;
    return $remove;
}
add_filter('qterest_contact_remove_attachments_after_request', 'theme_remove_attachment_after_request', 10, 3);

Formatting keys (ADMIN)

When looking at a contact request you can see that the name of the field identifies the value. This can be changed by adding a filter to display a better name for the customer. The filter name looks like this qterest_format_key_${key}.

function theme_format_keys_bulk($key) {
    return "Does this person have a dog?";
}
add_filter('qterest_format_key_has_dog', 'theme_format_key_has_dog');

You can also bulk format keys with the filter qterest_format_bulk_keys.

function theme_format_bulk_keys($key) {
    return [
        'has_dog' => "Does this person have a dog?",
        'email' => __("Email address", 'text_domain'), // TIP: You can use localization here if the site is multi language
    ]
}
add_filter('qterest_format_bulk_keys', 'theme_format_bulk_keys');

Fields

You can change the HTML of the fields with this filter. The filter name looks like this qterest_contact_field_${field_type}_html

Example of custom checkbox field

function theme_custom_checkbox_field_html($field, $args) {
    $newField = "<label for=\"$args[id]\">$args[label]</label>";
    $newField = "<input id=\"$args[id]\" type=\"$args[type]\" name=\"$args[name]\" value=\"$args[value]\"";
    return $newField;
}
add_filter('qterest_contact_field_text_html', 'theme_custom_checkbox_field_html', 2, 10);

Frontend

QTE Rest provides basic javascript to make the forms asynchronous. It also triggers events if the form submission succeeds or fails.

There is 2 events available to listen on.

• qterestSubmitted
• qterestError

Example usage of the events

$('.qterest-form').on('qterestSubmitted', function (event, data) {
    $('.somediv').html(`<h1>${data.success_msg}</h1>`) // qterestError contains error_msg instead
})

MailChimp

MailChimp is very esay to use with this plugin. All you have to do is to add a API key in the settings page and select the list you want the users to be added to.

Subscribe form

There is a helper function available for rendering MailChimp forms.

qterest_render_mailchimp_form(string $input_label, string $submit_label, bool $echo = false);

Example

qterest_render_mailchimp_form("Email", "Subscribe");

Filter

If you need to change the arguments of the field you can use the filter qterest_mailchimp_field_arguments.

Example usage of the filter

add_filter('qterest_mailchimp_field_arguments', 'theme_mailchimp_field_arguments');
function theme_mailchimp_field_arguments( $field ) {
    $field['type'] = 'text';
    return $field;
}
