WordPress | ACF PRO & Contact form 7 Create an event subscription form
A customer ask me to create, under his wordpress website, an Events Subscribe Form, at the moment, the events, are a custom post type with some acf fields associated.
Basically he wants to have the ability to add a maximum number of users that can register to the event.
When a user subscribe to the event, if there is disponibility of places, he ‘ll recive a mail with the payment datas, otherwise, he’ll recive a mail that inform him that there isn’t more disponibility of places.
First of all create 2 custom fields associated with the custom post type “Event”:
1° field : Label:disponibility Name:disponibility Type:number
2° field: Label:subscriber number Name:subscribe_number Type:number Default: 0
Second create a Form in “Contact form 7” open the “single-events.php” from you theme, and where you want the subscribe form appears add:
00001 | <?php echo do_shortcode( '[contact-form-7 id="144" title="Subscribe Events Module"]' ); ?> |
Change “id=” and “title=” with the one from your form.
Next, open the function.php from your theme and add:
00001 | add_action("wpcf7_before_send_mail", "wpcf7_do_something"); |
Basically this action performed when the mail is actually sent by CF7, now we have to create the “wp7_do_domething” function:
00001 00002 00003 00004 00005 00006 00007 00008 00009 00010 00011 00012 00013 00014 00015 00016 00017 00018 00019 00020 00021 00022 00023 00024 00025 00026 00027 00028 00029 00030 00031 00032 00033 00034 00035 00036 00037 00038 00039 00040 00041 00042 00043 00044 00045 00046 00047 00048 00049 00050 00051 00052 00053 00054 00055 00056 00057 00058 00059 00060 00061 00062 00063 | function wpcf7_do_something($WPCF7_ContactForm){//Get current form $wpcf7 = WPCF7_ContactForm::get_current(); // get current SUBMISSION instance $submission = WPCF7_Submission::get_instance(); $val_posti = $your_postid;if ($submission) { // get submission data $data = $submission->get_posted_data(); // nothing's here... do nothing... if (empty($data)) return; // extract posted data for example to get name and change it $name = isset($data['your-name']) ? $data['your-name'] : ""; // do some replacements in the cf7 email body $mail = $wpcf7->prop('mail'); // with $data['my-filed-name'] we extract the post/page id $posti_dis = (int) get_field('disponibilita',$data['my-filed-name']); //number of places ( from custom field associated with the custom post type ) $n_iscritti = (int) get_field('numero_iscritti',$data['my-filed-name']); //number of subscribers ( from custom field associated with the custom post type ) $post_riamanenti = $posti_dis - $n_iscritti; // Number of free places if(($posti_dis - $n_iscritti)>0){ // if (number of subscribers < number of places ) $mail[ 'subject' ] .= ' - Posti Disponibili'; $mail2 = $wpcf7->prop('mail_2'); $mail2['body'] = ' Buongiorno.<br/>Abbiamo ricevuto la sua richiesta di iscrizione.<br/>A breve invieremo una email di conferma di iscrizione con i dettagli dell’evento..<br/><br/>Qualora voglia partecipare anche alla cena conviviale, per perfezionare l'iscrizione, la invitiamo ad <br/> inviare la copia del bonifico all'indirizzo email <br><a href="eventi@ugdcecmonzabrianza.it">eventi@ugdcecmonzabrianza.it</a><br/>Il bonifico dovrà essere eseguito sulle coordinate Cordiali saluti.<br/>UGDCEC Monza e Brianza'; // Save the email body $wpcf7->set_properties(array("mail" => $mail,"mail_2" => $mail2)); $n_iscritti++; // Increment the number of subscribers update_field('numero_iscritti', $n_iscritti, $data['my-filed-name']); // Save the value in the relative custom fields return $wpcf7; }else{ // if (number of subscribers >= number of places ) $mail[ 'subject' ] .= ' - Posti non Disponibili'; $mail2 = $wpcf7->prop('mail_2'); $mail2['body'] = 'Buongiorno.<br/>Abbiamo ricevuto la sua richiesta di iscrizione.<br/>Al momento abbiamo superato il numero di posti disponibili.<br/><br/>Le comunicheremo a breve se è possibile confermare comunque la sua richiesta. <br/><br/><br/>Cordiali saluti <br/> UGDCEC Monza e Brianza <br><a href="eventi@ugdcecmonzabrianza.it">eventi@ugdcecmonzabrianza.it</a>'; // Save the email body $wpcf7->set_properties(array("mail" => $mail,"mail_2" => $mail2)); return $wpcf7; } // Save the email body $wpcf7->set_properties(array( "mail" => $mail )); return $wpcf7; } } |
For test it, navigate to post type, create new event, insert the number of “disponibility” in disponibility field ( the “subscriber” field must be 0 ).
Now try to overcome the disponibility limit, and you see that the email changes.
Tha’ all
Good luck !!!
