Sometimes you may want to add a contact form 7 form into a template directly. While normal use is via a shortcode eg,
[contact-form-7 id="200" title="My Contact Form"]
you can’t use this directly inside a PHP page template.
Instead, you need to wrap this inside the WordPress do_shortcode function, in order to enable it to parse correctly. Wrapping your form up like this will render it correctly in the page using this template:
<?php echo do_shortcode( '[contact-form-7 id="200" title="My Contact Form"]' ); ?>
And voila, you have a CF7 form embedded from inside a PHP page template.
