My main script ============ ========= =======
$result = new questions();
$result->ShortListC ategories( $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 Comments
$result->ShortListC ategories( $lang);
Function ShortListCategories ($lan) { ------------ --------- --------- - I'm not too sure, but I noticed the parameter sent to the function was "$lang", but the one that the function takes to use is "$lan" Hopefully, the problem is just that typo...
