Gravity Forms is a popular plugin for WordPress that allows you to easily create forms and surveys on your website. Using shortcodes, you can insert these forms into pages, posts, and widgets. In this article, we will focus on the PHP code used to generate these shortcodes.
Shortcodes are small pieces of code that allow you to insert predefined elements into your WordPress site. They can be used to insert anything from buttons and icons to more complex elements like contact forms and surveys.
For example, if you wanted to insert a contact form created using Gravity Forms, you could use a shortcode like this:
[gravityform id="1" title="true" description="true"]
This shortcode will insert the form with ID "1" onto your page or post along with its title and description.
To use Gravity Forms shortcodes, you will need to know the form ID and any additional parameters that you want to include, such as the form title and description. Here is an example of how to create a Gravity Form shortcode in PHP:
<?php
echo do_shortcode('[gravityform id="1" title="true" description="true"]');
?>
This code will output the Gravity Form shortcode on your page or post.
In addition to creating shortcodes, you can also manipulate existing shortcodes using PHP. For example, you might want to change the form title or description for a specific page.
To do this, you can use the following code:
<?php
$shortcode = '[gravityform id="1" title="true" description="true"]';
$modified_shortcode = str_replace('title="true"', 'title="Contact Us"', $shortcode);
echo do_shortcode($modified_shortcode);
?>
This code will replace the original shortcode's title parameter with a new title of "Contact Us".
Gravity Forms shortcodes are a powerful tool for creating complex forms and surveys on your WordPress site. With a basic understanding of PHP and shortcodes, you can easily add and manipulate these forms to meet your specific needs.
