Question

I created a form with a multidimensional arrays and I’m trying to send an e-mail with the arrays using PHPmailer by writing the contents of the arrays to a text file and then having it read the file for contents but when I send the e-mail it only shows up as “‘; } fclose(); ?> “. What am I doing wrong?

Here is the code of the form with the multidimensional array:

<form id="form" name="form" method="post" action="send_mail_tray.php" onsubmit='return packageValidator()'>
   <table width="100%">
      <tr>
        <td><input type="hidden" name="appetizer[]" value="Appetizer 1" />Appetizer 1</td>
        <td style="width: 75px" align="right">
            Med: <input type="text" name="appetizer[0][Med]" style="width: 30px" /><br />
            Lg: <input type="text" name="appetizer[0][Lg]" style="width: 30px" />
        </td>
        <td><input type="hidden" name="appetizer[]" value="Appetizer 2" />Appetizer 2</td>
        <td style="width: 75px" align="right">
            Med: <input type="text" name="appetizer[1][Med]" style="width: 30px" /><br />
        Lg: <input type="text" name="appetizer[1][Lg]" style="width: 30px" />
        </td>
        <td><input type="hidden" name="appetizer[]" value="Appetizer 3" />Appetizer 3</td>
        <td style="width: 75px" align="right">
            Med: <input type="text" name="appetizer[2][Med]" style="width: 30px" /><br />
            Lg: <input type="text" name="appetizer[2][Lg]" style="width: 30px" />
        </td>
      </tr>
      ...
   </table>
   <input type="Submit" value="Submit Order" />
</form>

My PHP code:

foreach ($_POST['appetizer'] as $piece => $sizes){
    $medSize = $sizes['Med'];
    $lgSize = $sizes['Lg'];
    if(!empty($medSize) || !empty($lgSize)){
        $appetizer .= $_GET['appetizer'] . " - Med: " . $medSize . ", Lg: " . $lgSize;
    }
}

$message = ("<p>Thank you for your catering request!</p>
    <p><b>Name:</b> $name<br />
    <b>Phone #:</b> $phone<br />
    <b>Email:</b> $email</p>
    <p><b>Appetizers:</b><br />
    $appetizer
    </p>");

I have also tried using andrewsi’s code but after using it, I no longer receive e-mails:

foreach ($_POST['appetizer'] as $piece => $sizes){
    $medSize = $sizes['Med'];
    $lgSize = $sizes['Lg'];
    if(!empty($medSize) || !empty($lgSize)){
        $message .= $_GET['appetizer'] . " - Med: " . $medSize . ", Lg: " . $lgSize;
    }
}

Here is the code for sending the e-mail:

$email = $_REQUEST['email'];
$mail = new PHPMailer();
$mail->Host = //SMTP server
$mail->Sender = //Sender
$mail->From = //From
$mail->AddReplyTo("[e-mail]");
$mail->FromName = //FromName;
$mail->AddAddress($email);
$mail->IsHTML(true);
$mail->Subject = //Subject;
$mail->Body=$message;
$mail->WordWrap = 50;
$mail->Send();
echo"<script>window.location='thankyou.html'</script>";

You need to rejig the last piece of code:

$message = "<p><b>Appetizers:</b><br />";

$fapp = fopen('appetizers.txt', 'r');
while(!feof($fapp)){
    $message .= fgets($fapp) . '<br />';
}
fclose($fapp);

You’re mixing code in with your email text – this way, you’re separating them out.

Edited to add:

You can also generate $message straight from $_POST:

foreach ($_POST['appetizer'] as $piece => $sizes){
    $medSize = $sizes['Med'];
    $lgSize = $sizes['Lg'];
    if(!empty($medSize) || !empty($lgSize)){
        $message .= $piece . " - Med: " . $medSize . ", Lg: " . $lgSize;
    }
}

That will save you writing and then reading a file.
