PHP - 电子邮件回复器中的复选框值显示

Question

I have checked all the questions first. But non of them helped to solve my problem.

I have PHP E-mail responder connected to HTML contact form. I need to display selected checkbox value inside the email responder which is sent to customer.

PHP code

<?php

if(isset($_POST) && ($_POST['send'] == 1)){

    $documents = array(
                    'document1' => 'http://www.example.com/document1.doc',
                    'document2' => 'http://www.example.com/document2.doc',
                    'document3' => 'http://www.example.com/document3.doc'
                    'document4' => 'http://www.example.com/document4.doc'
                );

    $to      = 'lubosmasura@gmail.com';
    $subject = 'Prihláška na školenie';
    $name = $_POST['name'];
    $email = $_POST['email'];
    $document = implode(", ",$post['document']);
    
    

    if(isset($_POST['document']) && count($_POST['document']) > 0){
        foreach($_POST['document'] as $doc){
            if(isset($documents[$doc])){
             $document = implode(", ",$post['document']);
             $message = "
             ŠKOLENIE: $document
             ";
        }
        }
    }


    $headers = 'From: noreply@marcelaskolenia.sk' . "\r\n" .
        'Reply-To: noreply@marcelaskolenia.sk' . "\r\n" .
        'X-Mailer: PHP/' . phpversion();
    $headers  = 'MIME-Version: 1.0' . "\r\n";
    $headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";

    mail($to, $subject, $message, $headers);
   }
   ?>

HTML code

<form method="post" action="test.php">
    
                            <p class="center">Vyberte školenie</p>
                            <label class="container riadok"><p for="document" class="dolava">§20 Poučená osoba</p>
                            <input type="checkbox"  name="document[]" value="document1" id="document">
                            <span class="checkmark"></span>
                            </label>
                            <label class="container riadok"><p for="document" class="dolava">Aktualizácia: §21 AŽ §24</p>
                            <input type="checkbox"  name="document[]" value="document2" id="document">
                            <span class="checkmark"></span>
                            </label>
                            <label class="container riadok"><p for="document" class="dolava">§21 Elektrotechnik</p>
                            <input type="checkbox"  name="document[]" value="document3" id="document">
                            <span class="checkmark"></span>
                            </label>
                            <label class="container riadok"><p for="document" class="dolava">§24 Revízny technik</p>
                            <input type="checkbox"  name="document[]" value="document4" id="document">
                            <span class="checkmark"></span>
                            </label>
                            <p class="center">Vyplňte osobné údaje</p>
                            <input type="text" name="name" id="name" class="form-control" placeholder="Meno">
                            <input type="text" name="email" id="email" class="form-control" placeholder="Email">
                            <input type="tel" name="phone" id="phone" class="form-control" placeholder="Telefónne číslo" pattern="[0-9]+"  title="Zadajte iba čísla." required="required">
                            
<input type="hidden" name="send" value="1" />
 <button type="submit" value="SEND" id="submit" class="btn btn-primary"> ODOSLAŤ PRIHLÁŠKU</button>

Email responder works but it does not display selected checkbox value from HTML form behaind message ŠKOLENIE: CHECKBOX HERE

Any ideas? Thank you

Answer 1

You don't have such a variable as $post , but you try to use it twice. Replace it with $_POST and your form will work.

This:

$document = implode(", ",$post['document']);

Replace with this:

$document = implode(", ",$_POST['document']);

And it should work.

Some hints:

1. Properly configured IDE will let you know about such errors as an undeclared variable. Use PHPStorm (commercial) or VSCode (free).
2. Don't close php tag (?>) at the end of your file (PSR2):

The closing ?> tag MUST be omitted from files containing only PHP.

3. Don't use the same identifier (id) multiple times. The id should be unique in the entire HTML document.

Edit: // As someone has mentioned in the comments, you don't have a closing tag for <form> tag, but I assumed that you pasted only a part of your HTML document. Otherwise, you should correct that as well.

Should be

if(isset($_POST['document']) && count($_POST['document']) > 0) {
    foreach($_POST['document'] as $doc){
        if(isset($documents[$doc])){
            $document = implode(", ",$_POST['document']);
            $message = "
            ŠKOLENIE: $document
            ";
        }
    }
}
