@dennis and @tyler. Your code needs to somewhere split the text field data from the form into words. As it stands now it is cycling over the $_GET fields (not words) on the page. I just updated that slide because I had been vague and send output all the words submitted on the page. I meant all the words in the text field data.

Hi Alejandro,
  1. The label element should have a for attribute to indicate which form element it is for.
  2. I'm not sure why you have the ob_start and ob_clean methods in the above -- their typically used only when you want to capture the output as a string -- which we don't need to do here.
  3. You shouldn't use things like str_replace in a view, we imagine a view being written and maintained by a web designer whose expertise is design not coding.
Best, Chris

Hi Sarika,
The "for" attribute of a label needs to point to an "id" attribute of some target element not the "name" attribute. Your code doesn't output each word from the form submission in a different div, it outputs each field that was submitted instead.

Here's mine:
<?php
function messageController() {
   //decide which view to use and set up data for output

	if(empty($_POST['data'])){
		formView($_POST[data]);
	} else {
		seenWordsView($_POST[data]);
	}
} function formView($data) {
   // $data has any data set up from the controller
   //outputs the message form
	echo "<form method='POST' action='<?php echo $_SERVER[PHP_SELF];?>'><label for='input'>Enter your message here:<input type='text' id='input' name='data'><input type='submit' value='Submit'></form>";
} function seenWordsView($data) {
   //outputs seen words, allowed a foreach loop and to
   //echo variables. Not allowed to call preg_ functions or explode
	$words = explode(" ", $data);
	echo "<h1>Words Seen</h1>";
	foreach ($words as $value) {
		echo "<div>". $value ."</div>";
	}
	echo "Click <a href='/message.php'>here</a> to go back to the form page ";
} messageController();
?>
