Re: strings in a function return

Im beginning to think that functions aren't all that cracked up to be. I may as well go back to my old "non function" way of coding. I was displaying the form in the function because the application Im using currently displays forms in functions. Ill try and see what I can do with this new found knowledge called 'functions'.....

top(); is a function that displays a menu, that works. <form> is where the form goes. In its current setup less the array/implode/explode/foreach loop I can get it to echo 'a' return that I specify. But its no good, when I have 7 seven fields in the form to process..... David Robley wrote:

<form>

$array = array("$new_cat,$assigned_to","$job","$assigned_by");

$string = implode("|",$array); return $string;

} The variables that form $array are from the form....

Hrm - undefined function top() ?? <FORM> ?? But the rest of it returns what I would expect - a comma followed by two | - given that I don't have the values referenced in the array. And | you won't either, as they aren't global and aren't passed as parameters.

Why are you putting the form inside the function? There surely must be a better way to achieve what you want (which is not clear from the snippet).
