Ok my first time asking question here. This as been very helpful in the past but now i'm lost. I'm trying to understand how php work with the help of a book. So i did the exercise as it was shown in the book and the result if not what it should be.
Here's the code:
<div id="content">
<p>Here's a record of everything in the REQUEST array:</p>
<?php
foreach($_REQUEST as $value) {
echo "<p>" . $value . "</p>";
}
?>
</div>
<div id="footer"></div>
</body>
And here's the result:
Here's a record of everything in the REQUEST array:
" . $value . " "; } ?>
Why is not showing the info it is suppose to? Thanks.
Ok here's all the code:
showRequestInfo.php
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
> "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html
> xmlns="http://www.w3.org/1999/xhtml"> <head> <meta
> http-equiv="Content-Type" content="text/html; charset=utf-8" /> <link
> href="/wamp/www/livrephp/css/phpMM.css" type="text/css"
> rel="stylesheet" />
>
> <title>Untitled Document</title> </head>
>
> <body> <div id="header"><h1>PHP & MySQL: The Missing
> manual</h1></div>
> <div id="example">Example 3-2</div>
>
> <div id="content">
> <p>Here's a record of everything in the REQUEST array:</p>
> <?php foreach($_REQUEST as $value) { echo "<p>" . $value . "</p>"; } ?>
>
>
> </div>
> <div id="footer"></div> </body> </html>
And this goes with this file called "socialEntryForm.php"
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

Are you sure your file is a PHP file and it's being run on a PHP enabled server? The browser seems to be receiving the code unparsed, thinking that there's a tag starting at <?php and ending at the first <p> tag. If you look at the source, you'll probably see your PHP code, untouched by the server.
In other words: Your code is correct and the problem is your file type or server configuration. If you are indeed using a server on your machine, make sure you're running the file right, e.g. if it's in the root, open http://localhost/your_file.php, and not C:\xampp\htdocs\your_file.php.
EDIT: Just for the heck of it, I replicated your issue with a fiddle. I got the exact same output as you, meaning it's not getting parsed by the server. Who said JSFiddle was only good for JavaScript?
$_REQUEST Contains data which is gathered from cookies, $_POST and $_GET .. Are you sure that your data is properly assigned?
Take this example.
print_r($_REQUEST); just doing that without no <form method="get/post"> will produce a blank array, that might be why you are getting nothing
Your snippet is correct.. you are lacking a html form to go with that..
Example:
<form method="POST">
<input type="submit" name="test" value="ThisIsCorrect">
</form>
With your code you have shown your question.. your $_REQUEST array will return the value of the button. In this case "ThisIsCorrect"
Moral Of this?
Ensure that you are using using post/get/cookies before calling the $_REQUEST, and for future reference, just using $_POST & $_GET is cleaner to use.. But that is down to my personal preference.
How is the $_REQUEST Array constructed?
Consider this:
the array will contain the name as the array key and the value as the value..
So taking this into account:
<form method="POST">
<input type="text" name="username">
<input type="submit" name="test" value="ThisIsCorrect">
</form>
For your text box & Submit button the array will be:
array ("username" => "UserInputData", "test" => "ThisIsCorrect");
