(Edited: 2016-02-24)@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.
<?php function messageController()
{
data = _GET;
formView(data);
if (data != NULL) {
ob_clean(); // clears the formView to prepare the page for the seenWordsView
output = str_replace(" ", "</div><div>", data["message_text"]);
seenWordsView(output);
}
}
function formView(data)
{
?>
<form method="get" action="message.php">
<label for="message_text">Enter your message here:</label>
<input type="text" name="message_text" size="10" />
<input type="submit"/>
</form>
<?php
}
function seenWordsView(data)
{
?>
<head>Words Seen</head>
<?php
echo "<div>data</div>"
?>
<a href="message.php">Back to form</a>
<?php
}
messageController();
Hi Alejandro,
The label element should have a '''for''' attribute to indicate which form element it is for.
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.
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.
Best, Chris
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();
?>
