There are times when using the Contact Form 7 WordPress plugin where you need to pass a parameter from the URL and into a hidden field or display it in the form. This plugin is great for passing things such as order numbers, selected packages, or even security information.

How do I add a Hidden Field?

When editing a form in Contact Form 7, enter the getparam shortcode. There is only one valid parameter which is the name of the $_GET value.

[getparam value]

For example, if the URL is http://mysite.com/contact?ordernum=12345, the shortcode will be:

[getparam ordernum]

Then when building the response email, you can pass the value with [ordernum]

How do I show a $_GET value on the form?

When editing a form in Contact Form 7, enter the showparam shortcode. There is only one valid parameter which is the name of the $_GET value.

[showparam value]

For example, if the URL is http://mysite.com/contact?ordernum=12345, the shortcode will be:

[showparam ordernum]

You cannot pass a value to the response email using this method, to do that, you will also have to add a hidden field.
