null $pages object

[davenorton]

Hi All

I'm new to process wire and haven't touched php in about 8 years, however, from the lack of questions on the subject, I'm assuming this is not a common issue and more than likely my own doing.

I am using the default site template t get to know the product and have added a simple function to the _func.php code file. I am further, using the default pages:

 

Now I have added the simple function:

function getHomePageName() {
    $homepageName = '';
    if($pages){
        $homepage = $pages->get('/');
        $homepageName = $homepage->name;
    }
    else
        $homepageName = 'Nothing found';
    return $homepageName;
}    
 

The $pages object  always null and the code                                                                                                                                                                                                                                                                                                                                                                                                           

Any help in determining why the the $pages object is null would be appreciated

 

Thanks

Hi @davenorton

Welcome to ProcessWire!

It is a scope problem: The $pages variable is not known inside your function by PHP. Use the global wire() function to get any API variable. At the beginning of your function, write this:

$pages = wire('pages');

And it should start to work.

Or if you prefer you could turn on the functions API: https://processwire.com/blog/posts/processwire-3.0.39-core-updates/#new-functions-api

and do this:

$homepage = pages('/');
