[SOLVED] IF URL Variable Exists?

[kyleldi]

Is it possible to make an IF statement run from a url variable?  What I want to do is write a small script that states IF a url variable exists, a script runs, while if it does not that script is skipped and the next script is ran.  any ideas?  Thank You!

    echo $_GET['var'];
    //Put script here
  }
?>

Better to use isset when checking for user defined variables ($_POST, $_GET, $_COOKIE etc). This will prevent Notice messages from appearing if the variable doesn't exist.

<?php
  if(isset($_GET['var'])){
    echo $_GET['var'];
    //Put script here
  }
?>

Ok, I put that in my code but i'm getting an "unexpected $end" error.  Any ideas?  What it's supposed to do is output the url variable if there is one, otherwise it shows one thing if there are items in the db that are active, or another thing if there are no active items.

 

<?php
  if(isset($_GET['positionid'])){
    echo $_GET['positionid'];
    echo '<div class="jobdetail">

You need to either add a } at the end of your code or change the 'else { if {' to 'else if {'

[wildteen88]

You have a missing closing brace. Add one before your closing php tag.

 

To see where your code blocks start/end you should indent you code.

if(isset($_GET['positionid']))
{
    echo $_GET['positionid'];
