[Support request] Store the referrer

[Tushar]

I have to pass in the web referrer to my pages. How do I store this when a user comes to my site and then pass the value to a form.

Hi there,

WordPress has the wp_get_referer() function you can use:

Thanks, I was aware of this.

The question I had was how can I use it in one of the generatepress pages

The Theme has little to do with it.
You can store the referrer in many ways. For example:

add_action('wp', function(){
    // conditional logic - if referrer is different to current request URL
    // if page ID is 99
    if ( wp_get_referer() && is_page(99) ) {
        global $my_variable;
        $my_variable = wp_get_referer();
    }
});

change the 99 to match the page you want to get the referrer on.
And i the referrer URL is different to the current request then it will store it in the global $my_variable
You can then access that variable from your form.
