Modified to store $_GET info as $_SESSION info

Hi,

I have modified the script below to store the info in a session before to in case users move around a site before they return to a landing page.

Please find below:

add_action( ‘wpcf7_init’, ‘wpcf7_add_shortcode_getparam’ );

/* BOF: Script to use Sessions */
//Source: https://www.ads-software.com/support/topic/using-session-in-wordpress
add_action(‘init’, ‘myStartSession’, 1);
add_action(‘wp_logout’, ‘myEndSession’);
add_action(‘wp_login’, ‘myEndSession’);

function myStartSession() {
if(!session_id()) {
session_start();
}
}

function myEndSession() {
session_destroy ();
}
/* EOF: Script to use Sessions */

function wpcf7_add_shortcode_getparam() {
if ( function_exists( ‘wpcf7_add_shortcode’ ) ) {
wpcf7_add_shortcode( ‘getparam’, ‘wpcf7_getparam_shortcode_handler’, true );
wpcf7_add_shortcode( ‘showparam’, ‘wpcf7_showparam_shortcode_handler’, true );
}
}

function wpcf7_getparam_shortcode_handler($tag) {
if (!is_array($tag)) return ”;

$name = $tag[‘name’];
if (empty($name)) return ”;

if ($_GET[$name] == NULL) {
$html = ‘<input type=”hidden” name=”‘ . $name . ‘” value=”‘. esc_attr( $_SESSION[$name] ) . ‘” />’;
} else {
$_SESSION[$name] = $_GET[$name];
$html = ‘<input type=”hidden” name=”‘ . $name . ‘” value=”‘. esc_attr( $_GET[$name] ) . ‘” />’;
}

return $html;
}

function wpcf7_showparam_shortcode_handler($tag) {
if (!is_array($tag)) return ”;

$name = $tag[‘name’];
if (empty($name)) return ”;

$html = esc_html( $_GET[$name] );
return $html;
}
