 * Hi all
 * I am not much of a coder but want to have a way to create [mk_button] with url
   link to include current query string.
 * Something like this:
 * example.com/?house=1
    [mk_button url=”/ref/<?house=1>”]
 * Does anyone know a simple method to update button reference to include current
   url query string?
 * Thanks in advance!

 * so you want the current query string from the url in the address and what do 
   you want to do with it exactly?
 * when you show a button on the page it should grab the house parameter?

 * Hi Shamai
 * Yes you are correct, the button should great the all of the query string from
   the URL. Eg:
 * URL
    example.com/?house=2 Button [mk_button url=”/ref/?house=2″]
 * URL
    example.com/?site=australia Button [mk_button url=”/ref/?site=australia”]
 * This allows for me to pass these parameters to a form which will then choose 
   the correct display.

 * Are you using a form plugin or did you make the form yourself?
 * Are you trying to populate fields in a form?

 * Hi Shamai
 * Yes, I am using Gravity Forms plugin. The form allows for capturing of data from
   the query string and to populate certain fields.
 * Users come in from external sites and I differentiate this by proving link something
   like this:
 * External site 1
    example.com/?house=2
 * External site 2
    example.com/?house=5
 * There is a button on my landing page which I want to direct url to example.com/
   ref and include the original query string:
    example.com/?house=2 example.com/?
   house=5
 * The form can then capture parameter house and update the field as required.
 * This helps me to track on the form where the lead is coming from.
 * Thanks again for looking into this.

 * I think you’d be better of capturing the query string in a Cookie, on first visit.
   And then using the `gform_field_value_` filter in Gravity Forms to populate the
   form.
 * So you’d have something like
 *     ```
       function prefix_remember_query_string() {
       	if ( isset( $_GET['query_string_to_remember'] ) ) {
       		setcookie( 'cookie_for_remembering', $_GET['query_string_to_remember'], 30 * DAYS_IN_SECONDS );
       	}
       }
       add_action( 'init', 'prefix_remember_query_string' );
   
       function prefix_populate_form_field( $value ) {
       	if ( isset( $_COOKIE['cookie_for_remembering'] ) ) {
       		$value = esc_attr( $_COOKIE['cookie_for_remembering'] );
       	}
       	return $value;
       }
       add_filter( 'gform_field_value_your_parameter', 'my_custom_population_function' );
       ```
   
 * Where `gform_field_value_your_parameter` is `gform_field_value_` then the parameter
   name as given in Gravity Forms. Read more about that here: [https://www.gravityhelp.com/documentation/article/using-dynamic-population/](https://www.gravityhelp.com/documentation/article/using-dynamic-population/)
