Deleted class and still calling it

[NotSureILikePHP]

Okay I thought I was finally starting to get the hang of php so I went through trying to clean up some code. I changed all instances of my class Cust to Customer just for clarification. That's when I ran into a weird problem. I had a page that shows a grid of customers and it was calling this function

 

 

//code that calls the class
$custs = Customer::objects();
 
//this is the class declaration
class Customer extends VerySimpleModel
implements TemplateVariable {

    static $meta = array(
        'table' => CUST_TABLE,
        'pk' => array('cust_id'),
        'joins' => array(
            'location' => array(
                'constraint' => array('cust_id' => 'loc.cust_id'),
            ),
            'service' => array(
                'constraint' => array('service_level' => 'service.id'),
            ),
        ),
    );
    
       var $cust_id;
    var $name;
    var $contact;
    var $fname;
    var $lname;
    var $contact_phone;
    var $phone_number;
    var $fax_number;
    var $location;
    var $domain;
    var $service_level;
    var $row;
    var $address;
    var $_location = null;
 
//this is the function causing problems
function Cust( $id=0 )
    {
        $this->id=0;
        if($id && ($info=$this->getInfoById($id)) ){
            $this->row=$info;
            $this->id=$info["cust_id"];
            $this->cust_name=$info["cust_name"];
            $this->domain=$info["domain"];
            $this->location=$this->getLocationInfo($id);
            //$this->note=$this->getNotes($id);
            $this->service_level=$info["service_level"];
        }
    }

 

When I change that last function to Customer it breaks my grid and the grid doesn't load. However, nothing in my code is now calling that function as doing a search on my entire project in eclipse gives me no results. If I leave it as Cust my grid works but when I click on a customer to edit that doesn't work unless the function is named Customer. What happened and why is this code still calling a function by his old name?

Because that function is most likely being treated as a constructor. In OOP (using older PHP 4 sytax, which what your code uses) when a function is named the same as the class it will be called automatically when a new instance of the class is initialized (created eg  $customer = new Customer()).

 

So if you rename your class to customer you must rename the cust() function the same.

 

This why this is happening

when I click on a customer to edit that doesn't work unless the function is named Customer.

I figured that part out but when I name it to Customer another page doesn't work (my data grid page). It only works when the function is named Cust even though I have removed every instance of that and changed it to customer.

PHP must be calling the cust() function from somewhere, it maybe being called as part of callback, from a function like call_user_func_array

 

When you name the function as Cust use debug_print_backtrace() inside the function. Maybe this help you identify where it is being called from.

Thanks I will try that backtrace. Haven't seen that trick yet.
