Imagine, you have a Gravity Form. And you want to have an easy way to show all the Merge Tags from that specific form, without having to click on it inside the confirmations or notifications area? Take for example this form:

Just install the plugin ‘GravityWP – Merge Tags‘ from the WordPress repository and use this shortcode to get a list of all your merge tags (from a specific Form ID):

Instead of using the ‘GravityWP – Merge Tags‘ plugin, you can also add this snippet to your functions.php file in your theme. Alert! You won’t get any updates on the code (with the plugin you will get them automatically in WordPress). But if you don’t want to install the plugin, just add this:

function gravitywp_get_mergetags( $atts, $content = null ) {
		extract( shortcode_atts( array(
		'formid' => '0'
		), $atts ) );
		ob_start();
		$form_id = $formid;
        $form = RGFormsModel::get_form_meta($form_id);
        $fields = array();

        if(is_array($form["fields"])){
            foreach($form["fields"] as $field){
                if(isset($field["inputs"]) && is_array($field["inputs"])){

                    foreach($field["inputs"] as $input)
					    echo "&#123;" . GFCommon::get_label($field, $input["id"]) . ":" . $input["id"] . "&#125;<br>";
                }
                else if(!rgar($field, 'displayOnly')){
                    echo "&#123;" . GFCommon::get_label($field) . ":" . $field["id"] . "&#125;<br>";
                }
            }
        }
		
		$output_string = ob_get_contents();
		ob_end_clean();
		return $output_string;
    }
	
add_shortcode( 'gravitywp_mergetags', 'gravitywp_get_mergetags' );
