  1 | # Gravity Forms Iframe Add-on
  2 | 
  3 | Embed a Gravity Form in an iframe on any site.
  4 | 
  5 | __Contributors:__ [Brady Vercher](https://github.com/bradyvercher)  
  6 | __License:__ [GPL-2.0+](http://www.gnu.org/licenses/gpl-2.0.html)
  7 | 
  8 | The typical process to embed a Gravity Form on a site where the plugin isn't installed requires:
  9 | 
 10 | 1. Developing a custom page template with necessary code to output form scripts and styles.
 11 | 2. Creating a new page in WordPress.
 12 | 3. Inserting the form shortcode in the new page.
 13 | 4. Manually writing an iframe tag with the page permalink and giving it a static height.
 14 | 
 15 | 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.
 16 | 
 17 | ## Features
 18 | 
 19 | * Selectively enable embedding for individual forms.
 20 | * Auto-resizing iframes.
 21 | * Override embed templates in a theme or child theme.
 22 | * Override settings via the embed src query string.
 23 | * Extends the Gravity Forms add-on API to seamlessly integrate with the WordPress and Gravity Forms interface.
 24 | * Protocol-relative URLs for embedding on secure sites (both sites need SSL).
 25 | 
 26 | ## Settings
 27 | 
 28 | The form title and description can be hidden independent of regular form display by toggling a checkbox after enabling the embedding setting.

 30 | ![Form Iframe Settings Screenshot](https://raw.github.com/bradyvercher/gravity-forms-iframe/master/screenshot-1.png)
 31 | _The form's iframe settings panel._
 32 | 
 33 | ### Overrides for Individual Iframes
 34 | 
 35 | If the title and description settings need to be changed per embed, they can be modified in the iframe `src` query string.
 36 | 
 37 | * **`dt`:** Set to `1` to display the form title; `0` to hide.
 38 | * **`dd`:** Set to `1` to display the form description; `0` to hide.
 39 | 
 40 | _**Example:** gfembed/?f=1&dt=0&dd=0_
 41 | 
 42 | ### Auto-resizing Script
 43 | 
 44 | 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.
 45 | 
 46 | ### Confirmation Screen
 47 | 
 48 | If you redirect users to another page upon submission and would like the iframe to automatically resize, include the following in the confirmation page:
 49 | `add_filter( 'gfiframe_print_resize_ping_script', '__return_true' );`
 50 | 
 51 | ## Template Hierarchy
 52 | 
 53 | Templates can be added in a theme or child theme to override the plugin's template. Use the following template names:
 54 | 
 55 | * gravity-forms-iframe-{$form_id}.php
 56 | * gravity-forms-iframe.php
 57 |

 84 | ## Changelog
 85 | 
 86 | ### 2.0.5
 87 | 
 88 | * Loaded the text domain on `init` rather than `plugins_loaded` to prevent notices in WordPress 6.7+.
 89 | 
 90 | ### 2.0.4
 91 | 
 92 | * Required composer/installers 1.0 or 2.0 to prevent conflicts when installed with Composer.
 93 | 
 94 | ### 2.0.3
 95 | 
 96 | * Declared a variable in the `Plugin` class to prevent dynamic proprety warnings in PHP 8.2+.
 97 | * Handled Gravity Forms config collections in the head section of the iframe template. This allows scripts to be "localized" and prevents JavaScript errors.
 98 | 
 99 | ### 2.0.2
100 | 
101 | * Updated embed code field in the admin panel to work with Gravity Forms 2.5+.
102 | * Passed an object instead of a string in the auto-resize message.
103 | * Changed the method for hiding the admin bar to improve reliability.
104 | * Added GitHub Update compatibility.
105 | 
106 | ### 2.0.1
107 | 
108 | * Made GravityFormsIframe_Addon::form_settings_fields() compatible with the parent class.
109 | 
110 | ### 2.0.0
111 | 
112 | * Moved to the Cedaro GitHub account.
113 | * Refactored the plugin structure.
114 | * Introduced a 'gfiframe_head' action in the template header.
115 | 
116 | ### 1.0.3
117 | 
118 | * Defined 'gravityforms_iframe' capability in the Add-on class to integrate with the Members plugin.
119 | 
120 | ### 1.0.2
121 | 
122 | * Fixed a long-standing bug that may have prevented scripts from loading in the iframe template.
123 | * Fixed deprecated notices in Gravity Forms 1.9+.
124 | 
125 | ### 1.0.1
126 | 
127 | * Deprecated the .php extension in the embed rewrite rule to prevent conflicts with WordPress Multisite.
128 | * Disabled the WordPress toolbar in iframes when forms are embedded on the host domain.
129 | * Added a POT file for translators.
130 | 
131 | ### 1.0.0
132 | 
133 | * Initial release.
