Adding filter to the Contact Form 7 response

Question

I have a Contact Form 7 that adds a new post when submitted. In the response text that displays after submitted, I would like to include a link to that post.

add_action( 'wpcf7_before_send_mail', function($contact_form, &$abort, $submission){ if ($contact_form->title == "Pledge"){ $name = $submission->get_posted_data("pledge-name"); $schoolid = $submission->get_posted_data("yes"); $id = wp_insert_post([ "post_type" => "pledge", "post_title" => "$school->name | $name", "post_status" => "draft", ]); } }, 10, 3); 

How can I insert the $id variable into the response text?

Answer 1

You need to filter the submission message after the CF7 plugin has set its response using the display message filter wpcf7_display_message. You an achieve this with an anonymous fuction hook,

add_action( 'wpcf7_before_send_mail', function ( $contact_form, &$abort, $submission ) { //do you post creation and get the $id. add_filter('wpcf7_display_message', function($msg, $status) use ($id){ switch($status){ case 'mail_sent_ok': //mail sent. $msg="Created post {$id}"; case 'mail_sent_ng'://mail failed to send. break; case '': //mail aborted. break; } return $msg; },10,2); }

Please find below a potential solution. It checks the status of the $id for being a \WP_Error (indicating the creation of the post failed). If it's not a error, it'll produce a simple message to give output the $id.

However, it should be noted that the code you've provided has an error and will likely produce a fatal error, because $school is undefined and you're accessing it like an Object. My code is based on your code and doesn't correct for this. So you'll need to apply this solution to your particular implementation and correct this.

Also, I've added $abort = true; in the case of error, so the form submission will be aborted. You can keep that or remove it depending on your requirements.

add_action( 'wpcf7_before_send_mail', function ( $contact_form, &$abort, $submission ) { if ( $contact_form->title == "Pledge" ) { $name = $submission->get_posted_data( "pledge-name" ); $schoolid = $submission->get_posted_data( "yes" ); $id = wp_insert_post( [ "post_type" => "pledge", "post_title" => "$school->name | $name", "post_status" => "draft", ] ); if ( is_wp_error( $id ) ) { $submission->set_response( 'There was an error creating the new post.' ); $abort = true; } else { $submission->set_response( sprintf( 'A new post has been created with the ID: %s.', $id ) ); } } }, 10, 3 ); return !$abort; }
