Embed a Gravity Form in an iframe on any site.

The typical process to embed a Gravity Form on a site where the plugin isn't installed requires:
- Developing a custom page template with necessary code to output form scripts and styles.
- Creating a new page in WordPress.
- Inserting the form shortcode in the new page.
- Manually writing an iframe tag with the page permalink and giving it a static height.
With the Gravity Forms Iframe add-on, just enable a setting to allow the form to be embedded and copy the code snippet. That's it. As a bonus, the iframe automatically resizes whenever the form height changes -- for instance, when fields are shown or hidden due to conditional logic.
- Selectively enable embedding for individual forms.
- Auto-resizing iframes.
- Override embed templates in a theme or child theme.
- Override settings via the embed src query string.
- Extends the Gravity Forms add-on API to seamlessly integrate with the WordPress and Gravity Forms interface.
- Protocol-relative URLs for embedding on secure sites (both sites need SSL).
The form title and description can be hidden independent of regular form display by toggling a checkbox after enabling the embedding setting.
If the title and description settings need to be changed per embed, they can be modified in the iframe src query string.
dt: Set to1to display the form title;0to hide.dd: Set to1to display the form description;0to hide.
Example: gfembed/?f=1&dt=0&dd=0
If the auto-resizing functionality isn't needed for a particular form, adjust the iframe's height attribute to accomodate the form and don't include the <script> tag when copying the embed code. Leaving off the script tag will save an HTTP request.
If you redirect users to another page upon submission and would like the iframe to automatically resize, include the following in the confirmation page:
add_filter( 'gfiframe_print_resize_ping_script', '__return_true' );
Templates can be added in a theme or child theme to override the plugin's template. Use the following template names:
- gravity-forms-iframe-{$form_id}.php
- gravity-forms-iframe.php
