Hi there,

I have a form with some processing code that I want to add to a page but I have no idea how to do this in a snippet!
Here’s the code I want to transform:

$messageSent = 0;

if(isset($_POST['submit']))
{
  include('processDetails.php');

  $processDetails = new ProcessDetails();

  if($processDetails->submitMessage()) {
     $messageSent = 1;
  }
  else {
    $processDetails->displayErrors();
  }
}

$detailsToken = $_SESSION['detailsToken'] = md5(uniqid(mt_rand(), true));

if ($messageSent == 1) {
	echo '<h2>Thank you!</h2>
			<p>Thank you for filling out the form!</p>';
} else {

echo '
<h2>Lovely Form</h2>
<form id="quoteForm" method="post" action="'. $_SERVER['PHP_SELF'] .'">
        	<label>Frist Name &#42;</label>
                    <input type="text" class="required" name="firstName" value="'; if(isset($_POST['firstName'])) { echo $_POST['firstName']; } echo'" />
...etc...
                
			
	    <input type="hidden" name="token" value="'. $detailsToken .'" />
			
            <p><input id="send" type="submit" name="submit" value="Submit" /></p>
        </form>';
}
?>

Any pointers? Do I just have to replace the echos with outputs? Will the snippet be able to read the posted data or do I have to pass it through the snippet call?
Is there an easier way to stick php on a page without using snippets?

Thanks

As with many things in modx there are many ways to do many things the quickest but most nasty way is copy the code you have into a new snippet.

Change

echo '<h2>Thank you!</h2>
			<p>Thank you for filling out the form!</p>';

to

return ('<h2>Thank you!</h2>
	 <p>Thank you for filling out the form!</p>')

and

echo '
<h2>Lovely Form</h2>
<form id="quoteForm" method="post" action="'. $_SERVER['PHP_SELF'] .'">
        	<label>Frist Name &#42;</label>
                    <input type="text" class="required" name="firstName" value="'; if(isset($_POST['firstName'])) { echo $_POST['firstName']; } echo'" />
...etc...
                
			
	    <input type="hidden" name="token" value="'. $detailsToken .'" />
			
            <p><input id="send" type="submit" name="submit" value="Submit" /></p>
        </form>'

EDIT ok that code needs more work but to display somthing you just return it from the snippet instead of echoing.

to

'<h2>Thank you!</h2>
			<p>Thank you for filling out the form!</p>';
} else {

return ('
<h2>Lovely Form</h2>
<form id="quoteForm" method="post" action="'. $_SERVER['PHP_SELF'] .'">
        	<label>Frist Name &#42;</label>
                    <input type="text" class="required" name="firstName" value="'; if(isset($_POST['firstName'])) { echo $_POST['firstName']; } echo'" />
...etc...
                
			
	    <input type="hidden" name="token" value="'. $detailsToken .'" />
			
            <p><input id="send" type="submit" name="submit" value="Submit" /></p>
        </form>')

I personally would look at using place holders and chunks see
