Function problem.

[Braveheartt]

Here's my code:

 

<?php require("menu.php"); ?>	

<?php if(isset($_POST['submit']))
$forum_n = $_POST['name'];
$bug_des = $_POST['bug_des'];
$screen1 = $_POST['screen1'];
$screen2 = $_POST['screen2'];
$screen3 = $_POST['screen3'];
$bug_type = $_POST['bug_type'];
$pri_lvl = $_POST['radio']; ?>

<center><font size=5 color="white">
<?php 

function pr(){
   echo $pri_lvl;
   } 
   
echo "Posted by: $forum_n <br />";
echo "Description: $bug_des <br />";
echo "Screenshots: $screen1 <br />";
echo "Priority: $pri_lvl <br />";
pr(); ?></font></center>



</body></html>

 

Everything works fine, but the function pr isn't working... It won't echo $pri_lvl. Why is that? What have I done wrong  ?

 

[craygo]

the value is not being sent to the function

 

try this

function pr($value){
   echo $value;
   }

 

Now pass the value to the function

 

pr($pri_lvl);

 

So any value you put in the parenthesis will be echo'd out

Or if you want a function with no input, then use "global" to tell the function the value of $pri_lvl. The function doesn't know because it wasn't told. Initializing $pri_lvl earlier on in the script isn't enough.

 

function pr(){
          global $pri_lvl;
          echo $pri_lvl;
          }

 

This will then do:

 

pr();

 

"Global" picks up the value of $pri_lvl and tells the function what it is.
