Wordpress Contact form 7 custom shortcodes

Question

Contact form 7 has some shortcodes, like [_date] to get todays date. But I want to display the date one week from now.

So I need to create a custom shortcode to Contact form 7 that takes say [next_week] and in the recived email the correct date is displayed.

Where and how do I create custom shortcodes to Contact form 7?

Answer 1

Add the following to your functions.php

wpcf7_add_shortcode('custom_date', 'wpcf7_custom_date_shortcode_handler', true);

function wpcf7_custom_date_shortcode_handler($tag) {
    if (!is_array($tag)) return '';

    $name = $tag['name'];
    if (empty($name)) return '';

    $next_week = date('Y-m-d', time() + (60*60*24*7)); 
    $html = '<input type="hidden" name="' . $name . '" value="' . $next_week . '" />';
    return $html;
}

Now in the "Form" field in CF7 GUI type [custom_date next_week]

Now you can use [next_week] in the message body.
