My main script
============================
$result = new questions();
$result->ShortListCategories($lang);
$temp="";
$test=explode("",$result);
ksort($test);
reset($test);
foreach ($test as $ab=>$ac){
$temp.="<OPTION VALUE=\"$ab\">$ac\n";
}
================================
everything before $temp=""; is working fine :)
ive added / re-added / changed the rest of the code a dozen times-
trying to get it to work...
Here is the function :-
======================================
Function ShortListCategories($lan) {
$query = "SELECT category_id, category_name FROM categories ORDER BY
category_id";
$result=mysql_query($query) or die(mysql_error());
global $categories;
while ($row = mysql_fetch_array($result)) {
$temp=trim($row[0]);
$categories[$temp]=trim($row[1]);
}
reset($categories);
return ($categories);
}
=======================================
everyting after (& including) global $categories; Ive added / re-
added & changed the codse a dozen times - & nothing works...
Basically, WITHIN the function - I can loop / read / view the
$categories array - & everything works fine - So i KNOW the data is
being stored correctly...
However, No matter what i do, I cannot "return" this/these value(s)
back to the main script...
my "latest" error message is -
Object of class questions could not be converted to string in (main
script file) etc....
Is it possible to retrieve the value from the function - & how ?
PS, Ive found lots of online tutorials - where the function is
includedin the *same* file as the main script.. - But hardly / not
enough examples - where the function is in a class - held in a
different file to the main script... - Unless the example is
$test=5; return $test; etc (very basic script - I find)
Thanks
