I was wondering if someone would mind taking the time to answer a few questions about arrays and how to get particular data from them. (i.e. CharacterProfiler.lua)

I'm attempting to create a concise list of how to do certain actions so that other users can stumble across the forum and possibly use this information to create their own mods (as I am working on in my spare time).

As many of you probably already know the general structure of the CharacterProfile.lua file is always the same. You can view arrays as a tier or series of tiers to get to your information much like stairs in a house...you can stop on the 2nd floor to see the bedroom or go to the 3rd floor and use the bathrom.

Using lua2phparray.php or some other form of lua parser you can "parse" the lua file into a php array. Once you do that the return will be a giant array with many small arrays on the inside. the first tier of that array in our case is rpgoCPpref generally and myProfile second.

now using...

Code: Select all

foreach(array_keys($myArray) as $realm_name)
    {
    $realm = $myArray[$realm_name];
    print_r(array_keys($myArray));
    echo "<br><br>";
    }
 

which outputs the following

Code: Select all

Array ( [0] => rpgoCPpref [1] => myProfile )

Array ( [0] => rpgoCPpref [1] => myProfile )  

is there a way to get and store the values rpgoCPpref and myProfile without knowing that they are called that...and stored in a variable able to be echo'd out without an array.

I ask this because the next few tiers are character names that are dynamic and are not consistant with each user.

I've attempted to look for several ways to do this but I'm not sure on exactly what to do to get those values.

Anyone mind giving me a hand?


Thanks

Well, as you already figured out, this array exist IRL, and is being parsed by the roster.
So, why not looking at at file update.lib.php, starting from line 288:

Code: Select all

    function processMyProfile()
    {
        global $roster;

        $output = '';
        $myProfile = $this->uploadData['characterprofiler']['myProfile'];

        $this->resetMessages();

        foreach( $myProfile as $realm_name => $realm)
        {
            $this->current_realm = $realm_name;

            if( isset($realm['Character']) && is_array($realm['Character']) )
            {
                $characters = $realm['Character'];

                // Start update triggers
                if( $roster->config['use_update_triggers'] )
                {
                    $output .= $this->addon_hook('char_pre', $characters);
                }

                foreach( $characters as $char_name => $char)
                {
                // Code hidden : CP version test and Character handling here.....
                }
                    $output .= "<br />\n";
                }

                // Start update triggers
                if( $roster->config['use_update_triggers'] )
                {
                    $output .= $this->addon_hook('char_post', $characters);
                }
            }
            else
            {
                $output .= $roster->locale->act['noGuild'];
            }
        }
        return $output;
    } 

Note that the code does search for each Character in the ['Character'] array with the (snipped in the code above) :

Code: Select all

    foreach( $characters as $char_name => $char) 

That's the power of the foreach php command. You don't need to know the index name(s) in the array.
In the loop, you'll find it in $char_name.

I've looked at this over and over but I didn't have the knowledge behind some of commands...such as.


foreach( $myProfile as $realm_name => $realm)

How is this read? For each array $myProfile as each key $realm_name has a value....do this (is that correct?)

Next I've seen this input a lot but I'm not sure how it works... $this->...I'm not sure of the abilities of that statement or it's scope (I can't find it on php.net anywhere).

Thanks for the help...the more I understand it the better I get, sorry for even more questions


***Edit***
I was able to find out that $this-> is a class and I'm looking more into how it's used in wowroster to help me better understand what a class is and what it can do.

If you haven't done so yet, read the first couple of chapters of the PHP manual on http://www.php.net/manual/en/ to get a grip on the language's base structure.

That's was my question, back in 1985, when I had a look at a language named Smalltalk that just came out. After that, it was C++ all over the place.

To make a long story very short : it has to do with this famous Object Oriented language structures. Understand them well - and you'll be driving a Porsch real soon.

Note : I'm still NOT driving a Porsche

Yup been reading a bit here and there to grasp onto things

Tuigii - Thanks, your original post started to make sense the more I dove into it over and over again.



Now I believe I'll be able to do exactly what I need to do but my problem will rely on optimizing what i'm trying to do...that will come later...first functionality
