$_GET and $_POST superglobals are empty, but shouldn't be

[chrispclay]

Hi, i am having problems with using superglobals. I have been trying to use the $_GET and $_POST superglobals but no matter which one i use, it doesn't print out anything. It doesn't print out what i am trying to reach from a form. Is it something to do with my php.ini file? I have read somewhere that it is something to do with the register_globals part but am still not sure. Is there something i should do to enable these superglobals? Any help would be much appreciated, Thanks Chris

Heya, Chris. Welcome to TSDN!

Changed thread title to better describe the problem (did you know that threads whose titles do not follow the Posting Guidelines actually get FEWER responses?).

$_GET and $_POST will only contain values if you are sending GET or POST variables, respectively.

To populate $_GET, you will need to append your variables to the query string. For example:

http://localhost/path/to/your/script.php?variable=value
 

If you then call this code in script.php:

print_r($_GET);
 

You will see this:

Array
(
    [variable] => value
)
 

Populating $_POST generally requires submitting a form.

For more information, have a look at this document.

What version on PHP are you using?
Can you post the begining of the <form>-tag and the PHP-code?

Hi yea sorry,

On my HTML page my code is . . .

<form action="calculate.php" method="POST">
        <p><strong> Input First Integer: </strong></p>
        <input type="text" name="Integer_one">
        <p><input type="submit" value="send"/></p>
</form>
 

Then linked from this is a php document with the following code . . . .

<?php
        echo $_POST['Integer_one'];
?>

Heya, Chris.

Please use CODE tags when posting source code. See the REPLY GUIDELINES on the right side of the page next time you post.

Hi.

I see no problem with that code. Under normal circumstances that code should print out the value you entered in the <input> box called 'Integer_one'.
That is, of course, assuming that the PHP code is in the file called 'calculate.php'.

If this isn't working... Are you sure you are not receiving any errors? Check out this thread to be absolutely sure.
