Fixing wpcf7_before_send_mail() hooks – Contact Form 7 Plugin

In wordpress Contact Form Plugin version 3.9 onwards the structure of the plugin changed, and this has had a major impact on the wpcf7_before_send_mail() hook usage. If you now want to access the email posted data – keys and post value, below shows the old method and then the new method. Hope it helps someone. Note that the posted_data object property no longer exists.

Old Method:

add_action("wpcf7_before_send_mail", "my_function");

function my_function(&$cf7)
{

foreach ($cf7->posted_data as $keyval => $posted) {
// use $keyval and $posted as elements in email forms
}

}

New Method:

add_action("wpcf7_before_send_mail", "my_function");

function my_function($cf7)
{
       $submission = WPCF7_Submission::get_instance();
       if($submission) {
       $posted_data = $submission->get_posted_data();
       foreach ($posted_data as $keyval => $posted) {
       // use $keyval and $posted as elements in email forms
       }
       }
}
