PHP text email message - remove part of message if no data or blank

[CBG]

Hi,

I am using PHP to send an text email message after a form is submitted

Use mail at the moment, to send a text email for example:

$subject = 'Subject';
$message = 'Message goes here' . "\r\n" .
'Name: ' . $name . "\r\n" .
'Does this have data: ' . $doesthishavedata  . "\r\n" .
'something else: ' . $hasdata  . "\r\n" .
'------------------------------------';

$to = '[email protected]';
$from = '[email protected]';
$headers = 'From: ' . $from . '' . "\r\n" . 'Reply-To: ' .  $from . '' . "\r\n" . 'X-Mailer: PHP/' . phpversion();

mail ($to, $subject, $message, $headers);

 

As you can see Does this have data part, if it does not how can I remove it from being sent in the email?
 

Thanks

An "if() construct" often comes in useful at times like this.

I have tried if like this

$subject = 'Subject';
$message = 'Message goes here' . "\r\n" .
'Name: ' . $name . "\r\n" .
if ($doesthishavedata != ''){
'Does this have data: ' . $doesthishavedata  . "\r\n" .
}
'something else: ' . $hasdata  . "\r\n" .
'------------------------------------';

But get an error PHP Parse error:  syntax error, unexpected 'if' (T_IF)
Now if there away to break up the message into bits, then I could most likely use an if

Would this work to break the message up

$subject = 'Subject';
$message = 'Message goes here';
$message .= 'Name: ' . $name;
$message .= 'Does this have data: ' . $doesthishavedata;
$message .= 'something else: ' . $hasdata;
$message .= '------------------------------------';

You can't concatenate an if() statement like that. Try

$message = 'Message goes here' . "\r\n" .
'Name: ' . $name . "\r\n";

if ($doesthishavedata != '') {
    $message .= 'Does this have data: ' . $doesthishavedata  . "\r\n";
}

$message .= 'something else: ' . $hasdata  . "\r\n" .
