Calling out a value

VDarkAzN

Here is the problem.

<input type="hidden" name="blah" value=2>
<?
$value = $_GET['blah'];
echo "$value";
?>

How do i make it so that the name is being called out on the same page, that gives me the value?

make the action attribute of your form tag point to itself.

an easy way to do it is use this variable
$_SERVER['PHP_SELF']

<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
  <input type="text" name="blah" value="<?php echo $_POST['blah']; ?>">
  <input type="submit">
</form>

the problem is that I dont want to make it so ur using a form. I just want the value to be called out by using the name.

rehfeld

oh ok.

assuming your script name is test.php

goto this url
test.php?blah=something

and you code should output the value

and if you want it in a link, do like this
<a href="test.php?blah=something">something</a>

Uh what?

If you don't want to use a form, then what exactly is the purpose of this input hidden field in your original post? (Especially since a user can't change a hidden input's value on a web page)

<input type="hidden" name="blah" value=2> 
<? 
$value = $_GET['blah']; 
echo "$value"; 
?>

Also, the $_GET super global is only created by either passing a variable in a URL with an anchor link like this:

<a href="link.php?blah=blah">Link</a>

Or by passing it through a form as rehfeld suggested.

Me thinks you need to better explain what it is you are trying to do.
