GET works, POST doesn't...why?

dbrb2 · Sep 16, 2006

Hi,

I've been playing around with PHP after a bit of an break. I am using PHP version 5.2, with Apache server version 2.2.

Everything seemed fine, but when playing around with using POST and GET to fill variables in a php script GET works fine, but POST does not. This seems odd... any suggestions?

Code:

<html>
<form action="post.php" method="post">
Test: <input type="text" name="test"><br>
<input type="Submit">
</form>
</html>

And...

Code:

<?php
$input=$_POST['test'];
echo $query;
?>

Does not work. However...

This...

Code:

<html>
<form action="get.php" method="get">
Test: <input type="text" name="test"><br>
<input type="Submit">
</form>
</html>

And this

Code:

<?php
$input=$_POST['test'];
echo $query;
?>

Does work. I can't see why...

Any suggestions? I suspect it is something obvious!

Try this:

Code:

<?php
$input=$_[COLOR=red]GET[/color]['test'];
echo $query;
?>

Cheers,
Jeff

Why do you use

Code:

$input=$_POST['test'];
echo $query;

instead of

Code:

$input=$_POST['test'];
echo $input;

? If you want to display the contents of the variable, you need to use the correct variable name.

Oops... I typed the code samples out incorrectly. As you have both suggested, I should have put $test instead of $query, and
in the second case used $_GET instead of $POST.

However, in the actual code I did both of these things.... (but somehow managed to mess it up when posting here!)

Another prime example where copying and pasting your code is SO important. Please copy and paste your code here so we can see what we're REALLY working with.

Try outputting your entire $_POST and $_GET arrays.

Post usually works better with long data strings than get because the browser can lop off the url after so many characters. Post maintains all the data.

Assuming your code is correct, your webserver is likely misconfigured. Not likely, but it's what it would take to have this happen.

As suggested by Miros, just dump them both to screen...

Code:

echo '<pre>GET:';
print_r($_GET);
echo '<hr>POST:';
print_r($_POST);

Then you'll at least rule out the typo possibilities.
