Get variable of the url and attach it on subject of content form mail

Hi,

I use the contact form of enfold and on forms pages, I need to get a variable that I put for Get in the url from Google Adwords

The question is: is the variable already set when the user comes to the contact form page?

If the page url of the contact form page contains the variable – i.e. like https://mywebsite.com/contact/?myvariable=4356754

you can use this code:

add_filter('avf_sc_contact_form_elements', 'avf_shortcode_sc_contact_form_elements', 10, 4);
function avf_shortcode_sc_contact_form_elements($form_fields, $atts) 
{
	$data = '';
	$googlevariable = 'myvariable';

	if(!empty($_REQUEST[$googlevariable]))
	{
		$data = htmlspecialchars($_REQUEST[$googlevariable]);
	}

	if($data)
	{
		$form_fields[$googlevariable] = array('label' => '', 'type' => 'text', 'value' => $data); 
	}

	return $form_fields;
}

to dynamically generate a new form field based on the variable (must be a php variable). You can replace myvariable with any other variable name.

The e-mail which is then send out will contain the variable value. You can also use the filters I posted here: https://kriesi.at/support/topic/formating-the-email-sent-via-contact-form/#post-1009256 to modify the message. If you want to alter the subject you can use this code

add_filter('avf_form_subject','avia_change_mail_subject', 10, 3);
function avia_change_mail_subject($subject, $new_post, $form_params) {
    $subject .= urldecode($new_post['4_1']);
    return $subject;
}

and replace 4_1 with the field id of the field which contains the variable information.

Hi,

Please try this code:

add_filter('avf_sc_contact_form_elements', 'avf_shortcode_sc_contact_form_elements', 10, 4);
function avf_shortcode_sc_contact_form_elements($form_fields, $atts) 
{
	$data = '';
	$googlevariable = 'myvariable';

	if(!empty($_REQUEST[$googlevariable]))
	{
		$data = htmlspecialchars($_REQUEST[$googlevariable]);
	}

	if($data)
	{
		$form_fields = array($googlevariable => array('label' => '', 'type' => 'text', 'value' => $data )) + $form_fields;
	}

	return $form_fields;
}

Best regards,

Hi,
I now tested the code and obviously it’s not possible to make the hidden field the first one without breaking the code. I’d recommend to leave it at the end to use the field type hidden to hide it. Use this code for the form:

add_filter('avf_sc_contact_form_elements', 'avf_shortcode_sc_contact_form_elements', 10, 4);
function avf_shortcode_sc_contact_form_elements($form_fields, $atts) 
{
	$data = '';
	$googlevariable = 'myvariable';

	if(!empty($_REQUEST[$googlevariable]))
	{
		$data = htmlspecialchars($_REQUEST[$googlevariable]);
	}

	if($data)
	{
		$form_fields[$googlevariable] = array('label' => '', 'type' => 'hidden', 'value' => $data); 
	}

	return $form_fields;
}

Best regards,
Peter

Hi!

You could use a prefix to mark your data – i.e. use this code

add_filter('avf_sc_contact_form_elements', 'avf_shortcode_sc_contact_form_elements', 10, 4);
function avf_shortcode_sc_contact_form_elements($form_fields, $atts) 
{
	$data = '';
	$googlevariable = 'myvariable';
	$prefix = 'gv_';
	
	if(!empty($_REQUEST[$googlevariable]))
	{
		$data = htmlspecialchars($_REQUEST[$googlevariable]);
	}
	
	if($data)
	{
		$form_fields[$googlevariable] = array('label' => '', 'type' => 'hidden', 'value' => $prefix.$data); 
	}

	return $form_fields;
}

– in the example I used the prefix ‘gv_’.

Then – in your filter code – you can use it to determine the right data field. I.e.:

add_filter('avf_form_message', 'avf_form_message_mod_new_field', 10, 3);
function avf_form_message_mod_new_field($message, $new_post, $form_params) {
	$message = '';
	$prefix = 'gv_';
	
	foreach($new_post as $key => $data)
	{
		$pos = strpos($data, $prefix);
		if($pos !== false && $pos == 0)
		{
			$message = substr($data, strlen($prefix));
		}
	}

    return $message;
}

would replace the message with the content of your variable. If you want to append the content of the variable with some text to the message use:

$variabletext = 'My variable is: ' . substr($data, strlen($prefix));
$message .= $variabletext;
