Redirect to an external URL with form input


function cf7_custom_form_url( $form_url ) {

global $post;

//The page id where the form is
$form_page_id = 18;

if ( $post->ID === $form_page_id ) {
return 'https://www.mywebsite.com/externalurl/';
}
else{
return $form_url;
}

}
add_filter( 'wpcf7_form_action_url', 'cf7_custom_form_url' );

Thank you for the quick response!

– Where should I place this code exactly? in the Additionnal settings of Contact Form 7, right? Somehow it doesn’t get triggered by the submit button.
– page id: should this be the wordpress page ID or the form ID? I tried with both
– I guess I should replace form_url with my own variable from the form?

I tried all of this but nothing happen. I do not understand how this could redirect the user on an external page with the right zip code.

I tried this

function cf7_custom_form_url( $zip-code) {

global $post;

//The page id where the form is
$form_page_id = 27;

if ( $post->ID === $form_page_id ) {
return ‘https://www.rehabs.com/find-a-rehab/?loc=’;
}
else{
return $zip-code;
}

}
add_filter( ‘wpcf7_form_action_url’, ‘cf7_custom_form_url’ );
