Javascript in PHP?

[prudens]

echo "<a href=" . "javascript:history.back();" . ">Return</a>";

 

 

How come it doesn't work??

[ignace]

javascript is a client-side language, php a server-side language

 

use instead

 

<?php

if (array_key_exists('HTTP_REFERER', $_SERVER)) {
   header('Location: ' . $_SERVER['HTTP_REFERER']);
} else {
   echo "<a href=\"#\" onclick=\"javascript:history.go(-1);\">click here to go back</a>";
}

?>

You are losing your quotes around javascript:history.back();. 

 

The site won't let me save the example code for some reason so here is another example instead...

 

 

echo '<a href="jscript:hist.back();">Return</a>';
