Functions question

Anon

I have created a function

function topPageURL($array='')

that optionally takes an array (most likely HTTP_POST or GET_VARS) and returns a variable $cfgToTop that contains the URL with any appended vars (ie: after the ?) to link to the top of the current page.

Works fine.

What I am trying to do is to incorporate this function inside another that creates a standard page footer:

// PAGE FOOTER function
function pacrimFooter($array=''){

topPageURL($array);

global $cfgToTop;

echo "\t\t</td>\n";
echo "\t</tr>\n";
echo "\t<tr bgcolor=\"#ffffff\" valign=\"bottom\">\n";
echo "\t\t<td align=\"right\"><a href=\"" . $cfgToTop . "\"><img src=\"images/top.gif\" width=\"48\" height=\"24\" alt=\"^ top of page ^\" border=\"0\"></a></td>\n";
echo "\t</tr>\n";
echo "</table>\n";
echo "</body>\n";
echo "";
}

This function works fine too, except that I am trying to pass $array from the pacrimFooter($array) function into the embedded topPageURL($array)function

Can I do that ???? If so how?

The only way that you can do this by passing the contents of the array is by using a session to handle the passing of the array. Look around the site and also php.net for more information on using sessions. The two main functions you need to learn about are:
session_start()
session_register()

OR
this would not be pretty but you could seperate the array back to the elements they represent and pass them then reconstruct them on the other page. lol... Look into sessions.
http://foo.com/bar.php?1=this?2=is?3=the?4=array

I should be beaten down for suggesting the latter.
Good luck...

I actually got it out a moment ago...

all I had to do was assign $array to a new global array - $newarray, then feed that into the embedded function, ie:

function pacrimFooter($array=''){

global $newarray;
$newarray = $array;

// get the top of page URL from the topPageURL() function (defined below)

topPageURL($newarray);

etc...etc...

that works fine....

thanks for your reply though
