Get original URL referer with the condition - php

Question

I need to collect data through a contact form and track customer referrals. I am creating a tag for the form, but I need it to be filled only if there was a transition from a referral that contained partner
my code
// Original Referrer
function wpshore_set_session_values()
{
if (!session_id())
{
session_start();
}
if (!isset($_SESSION['OriginalRef']))
{
$_SESSION['OriginalRef'] = $_SERVER['HTTP_REFERER'];
}
if (!isset($_SESSION['LandingPage']))
{
$_SESSION['LandingPage'] = $_SERVER["REQUEST_URI"];
}
}
add_action('init', 'wpshore_set_session_values');
///
function getRefererPage3( $form_tag ){
$partner = array (
'/partner/',
);
$parts = parse_url($_SERVER['HTTP_REFERER'];
if (!empty($parts['path']) || in_array($parts['path'], $partner)){ //this row. I doubt how it should be
if ( $form_tag['name'] == 'referer-page3' ) {
$form_tag['values'][] = $_SESSION['LandingPage'];
}
}
return $form_tag;
}
if ( !is_admin() ) {
add_filter( 'wpcf7_form_tag', 'getRefererPage3' );
}

Answer 1

I found my problem. Maybe this solution will help anyone in the future.
function getRefererPage3( $form_tag ){
if (strpos($_SESSION['LandingPage'], 'partner') !== false) {
if ( $form_tag['name'] == 'referer-page3 ) {
$form_tag['values'][] = $_SESSION['LandingPage'];
}
}
return $form_tag;
}
if ( !is_admin() ) {
add_filter( 'wpcf7_form_tag', 'getRefererPage3' );
}
