i am having trouble passing variables in the URL... I have simlified the problem here:

index.php contains the code:

<?
$var = "smile";
echo $var;

echo "<a href=\"index.php?var=notworking\">Change_Var</a>";

?>

and for whatever reason this does not change the value of var?

    <?php
$var = "something";

echo '<a href="index.php?var='.$var.'">The Link</a>';
?>

      <?

      echo $_GET['var'];

      $var = "smile";
      echo $var;

      echo "<a href=\"index.php?var=notworking\">Change_Var</a>";

      ?>

        

 if (!isset($_GET['var']))
 {
$var = "something";}
else{
 $var = $_GET['var'];}
 echo $var." <p>";



echo '<a href="index.php?var=hello">The Link</a>';

          Are you passing variables Out of a PHP script appended to a URL? looks like it.

          I can't seem to find anyone understanding well enough to give advice. I get hints like $_GET, but no examples.

          Do you have this working?

          Thanks for any bones...

            No examples? Look at the post right above yours. Perfect example.

              put the $ sign before print a variable

              <?
              $var = "smile";
              echo $var;

              echo "<a href=\"index.php?$var=notworking\">Change_Var</a>";

              ?>

                Time to end this thread...

                <?php

  //set the variable that you want to pass in the URL
  $var = "smile";

  //build the link
  //remember that ? tells the browser that there are global variables coming
  //var is the name of the value's key, and whatever comes after
  //the = sign is the value.  So ... smile
  //will be placed in the $_GET global array under the 
  //key name 'var'.  Accessing it via $_GET['var']
  echo '<a href="'.$_SERVER['PHP_SELF'].'?var='.$var.'">Click Me</a>';

  //this portion below will load if the link has been clicked  
                
  //make sure that $_GET['var'] is not empty
  if(!empty($_GET['var']))
    echo $_GET['var']; //this outputs "smile" without quotes

  //hope that helps.
  //if not, let me know and I can try again
?>
