Functions :)
 
Ok, i will try and make this as simple as i can.

I am making a script that is somewhat like diablo 2, where you have an inventory, and a dropdown menu with item stats and other things. Like in diablo 2, there are requirements and you need to achieve that score before you can equip that item. I have a quick function to get the requirements and spit them out.

PHP Code:
function requirements($itemid, $userid)
{
    global $db, $itemTypes;
    $req = $db->query_first("SELECT * FROM `abp_items` WHERE `id` = '$itemid'");
    if($userid != 0)
    {
        $usr = $db->query_first("SELECT * FROM `user` WHERE `userid` = '$userid'");
    }
    $equip = TRUE;
    if($req['req_lvl'] != 0 and $usr['level'] >= $req['req_lvl'])
    {
        $requiremnt .= '
        <div width="50%" style="background-color: #CCFFCC">
            Required Level: '.$req['req_lvl'].'
        </div>';
    
    }
    elseif($req['req_lvl'] != 0 and $usr['level'] < $req['req_lvl'])
    {
        $requiremnt .= '
        <div width="50%" style="background-color: #FFCCCC">
            Required Level: '.$req['req_lvl'].'
        </div>';
        $equip = FALSE;
    }
.....

    return $requiremnt;
    return $equip;
} 
I run this function in 1 place, but it will be soon be 2. How do i get $equip, without getting $requirement?

PHP Code:
$var = '<div id="item'.$total.'_menu" style="width: 25%; height: auto; display:none; padding: 4px; border-style: dotted; border-width: 1px;" class="alt2"> 
            <div style="width: 75%">
                '.$description.'
            </div>
            <hr width="40%">
            '.requirements($id, $userid).'
            <hr width="40%">
            '.attributes($id).'
        </div>'; 
In the function you see $equip, when it is set to true, there is a link that enables you to equip the item. If it is set to false there is no link beacuse they have not met the requirements.

How do i make it so that i can go

PHP Code:
requirements($id, $userid)
if($equip == true)
{
    echo '<a href="#equip....">You can equip this item</a>';
} 
$equip should be set? right, or do i need to use global?

Thankyou

Im guessing that i dont need to use 'return' is there some other value that i should be using?

Store $requirement and $equip in an array and then return the array ;

PHP Code:
$ret = array();
$ret['equip'] = $equip; 
$ret['requirement'] = $requirement; 
return $ret 
Then you can do this ;

PHP Code:
$req = requirements($id, $userid);
if($req['equip'] == true)
{
    echo '<a href="#equip....">You can equip this item</a>';
} 
(it would be better to store them in the array all through original function code, rather than just assign them at the end)
