OOP variables or array How to return variable

[Tsalagi]

I'm not versed in PHP OOP and I have some code that I need to echo out onto a page. I don't know what the meaning of $ct->something is in this code. Is this an array of some type? How do I echo out the $ct->title onto another page? Use a function call? I just don't know what all of the $ct variables are and how to get to them. Any help is appreciated.

function current_theme_info() {
    $themes = get_themes();
    $current_theme = get_current_theme();
    if ( ! isset( $themes[$current_theme] ) ) {
        delete_option( 'current_theme' );
        $current_theme = get_current_theme();
    }
    $ct->name = $current_theme;
    $ct->title = $themes[$current_theme]['Title'];
    $ct->version = $themes[$current_theme]['Version'];
    $ct->parent_theme = $themes[$current_theme]['Parent Theme'];
    $ct->template_dir = $themes[$current_theme]['Template Dir'];
    $ct->stylesheet_dir = $themes[$current_theme]['Stylesheet Dir'];
    $ct->template = $themes[$current_theme]['Template'];
    $ct->stylesheet = $themes[$current_theme]['Stylesheet'];
    $ct->screenshot = $themes[$current_theme]['Screenshot'];
    $ct->description = $themes[$current_theme]['Description'];
    $ct->author = $themes[$current_theme]['Author'];
    $ct->tags = $themes[$current_theme]['Tags'];
    $ct->theme_root = $themes[$current_theme]['Theme Root'];
    $ct->theme_root_uri = $themes[$current_theme]['Theme Root URI'];
    return $ct;
}

The '->' is the object-to-member operator, with a 'member' being either a field in the object (object data like a string, integer, etc.) or method of the object (function that acts on the object itself).  So, for something like ct->title, 'title' is a field of the ct object.  In the case of this current_theme_info() function, it's assigning all of these array values to particular fields within the ct object.  After this function is run, if you wanted to output the title, all you'd need to do would be:

 

echo ct->title;

 

Hope this helps.

Thanks. That works if I want to use it outside of another function, but when I want to use it as a parameter it doesn't work.

I tried putting $ct into an array which I can use print_r to view it but I don't know how to target

$ct->title as a $key $value

pair and then pass that into a variable using a foreach statement. Any suggestions?

You can't use an object member like that unless it's an array itself.

 

You can simply use the title as a function parameter:

 

function someFunction($arg)
{
   // do something
}

someFunction($ct->title);

Okay. I'll have to re-plan this one. Thanks a bunch!

Thanks for the link to post rules too.
