Posting variables to PHP via broswer.

[ultrajeeps]

Hello everyone,

I would highly appreciate it if you someone can point my mistake in this. I have a very simple php script which post a single variable called email. I would like to test the POST method from browser by extending the query string like this:

http://localhost/email.php?email=&helloworld

here is my script:

<?php
   
 $email = $_POST['email'];
echo $email;
?>

It's $_GET for the query string, or you can use $_REQUEST which combines both post, get and cookie

Hello Mounty,

How can I make sure that a variable is being posted if POST is being used instead of GET, please.

Thanks.

I think this is what you are asking.
The code below will only give the variable a value if the GET method is used, which is normally via the url. If the POST method is used the user will receive the no value message.
Also, be sure to validated the user's input.

$email = $_GET['email'];
if (isset($email) && $email != '') {
 echo $email;
} else {
echo 'No value given.';
}

You would use this if you wanted to use $_POST...

if(isset($_POST['variable'])){
echo 'Post variable posted.';
}else{
echo 'Post variable not posted.';
} 

Or you could do it the shorthand way...

echo (isset($_POST['variable']))? 'Variable posted':'Variable not posted';

Use this to check if POST data was sent:

if ($_SERVER['REQUEST_METHOD'] == "POST")

hope that's some help?

Thank you so much for all your help.

If you just want to check they are being passed, install Firefox and Firebug extension, which can show you POST requests and the content of variables.
