Lite Contact Form

FAQ

How to change sender and recipient email address?

By default, the plugin uses the administrator’s email address which is set in the WordPress general settings. It can be changed by adding attributes to the shortcode.

[contact_form sender="noreply@domain.tld" recipient="Blog Admin <admin@domain.tld>"]

How to protect contact form against spam?

The plugin has no built-in spam protection features, but is integrated with other plugins which do that job in the best way. You can use for it plugin Akismet or/and GreCAPTCHA.

Will this plugin work with cache plugins?

Yes. The plugin was designed to work with cache plugins. It uses lightweight Vanilla JS script and WordPress REST API to process requests.

How to change the style of the contact form?

By default, the fields description is displayed in placeholders, but you can change it to labels.

[contact_form style="labels"]

If you want only to change CSS style just add selectors to file style.css in active theme or create new file lite-contact-form.css in active theme.

How to add custom fields?

The plugin is simple and there are no settings to add custom fields, you need to add PHP code e.g. in functions.php in the active theme.

Use the add_filter function to add a custom field, there are three filters that you can use.

function custom_fields_before() {
    return '<p class="lcf-validate">
        <input type="text" name="test" placeholder="Field with JS validation">
        <span class="lcf-tip"></span>
    </p>';
}
add_filter('lcf_before_fields', 'custom_fields_before');

function custom_fields_before_message() {
    return '<p>
        <input type="text" name="test" placeholder="Field without JS validation">
        <span class="lcf-tip"></span>
    </p>';
}
add_filter('lcf_before_message_field', 'custom_fields_before_message');

function custom_fields_after() {
    return 'some html code';
}
add_filter('lcf_after_fields', 'custom_fields_after');

You can validates the entire request or only your field.

function custom_field_validate($result, $field, $value) {
    if(empty($value)) {
        $result['status'] = 'blocked';
        $result['fields'][] = array('field' => $field, 'message' => 'This field is required.');
    }
    return $result;
}
add_filter('lcf_validate_field_name', 'custom_field_validate', 10, 3);

function custom_validate_request($result, $fields) {
    if(...) {
        $result['status'] = 'error';
        $result['message'] = 'There was an error trying to send your message.';
    }
    return $result;
}
add_filter('lcf_validate', 'custom_validate_request', 10, 2);

There are two more filters that you can use to change the email subject and the message body.

function custom_mail_subject($subject, $fields) {
    return $subject;
}
add_filter('lcf_mail_subject', 'custom_mail_subject', 10, 2);

function custom_mail_message($message, $fields) {
    return $message;
}
add_filter('lcf_mail_message', 'custom_mail_message', 10, 2);
