NYCPHP Meetup

[Kristina Anderson]

One of the projects I inherited recently contains the following code 
which is used basically to store the record ID and editstate in the 
URL's querystring.  When I first saw it, I was scratching my head 
saying, why would anyone think they needed to do it this way?  

(My preferred way to store data such as this would be in hidden fields 
which are submitted with the form, but I do realize that everyone has 
different coding styles.  And mind you, they do have hidden fields 
which do contain IDs for other purposes...)

The script in the document head is

<script language="javascript">
function jfunc(arg){
	window.location='thissamedocument.php?id='+arg+'&edit=false';
}
</script>

and then throughout the page this script is called by echoing the 
following:

                echo "<SCRIPT LANGUAGE='JavaScript'>\n";
		echo "javascript: jfunc(" . $whateverID . ")\n";
		echo "</script>\n";

Would love to hear any and all comments on the above vis a vis this 
discussion.
