problem with new table and tabs in paneladmin

[adrub]

Hi Everyone!

I wanted to add into my shop editable list of distributors.
So I created table in db:

create table ps2_distributors(
ID_distributors int not null auto_increment,
Name varchar(100),
Country varchar(100),
Province varchar(30),
City varchar(100),
Address varchar(200),
Telephone varchar(100),
Email varchar(100),
Website varchar(200),
PRIMARY KEY(ID_distributors)
);

And I added a new tab in admin panel.

Then I created my class in AdminDistributors.php

class AdminDistributors extends AdminTab
{
   function __construct()
   {

        $this->table = 'distributors';
        $this->className = 'Distributors';
        $this->edit = true;
       $this->delete = true;

       $this->fieldsDisplay = array(
       'Name' => array('title' => $this->l('Name'), 'width' => 160),
       'City' => array('title' => $this->l('City'), 'width' => 160),
       'Province' => array('title' => $this->l('Province'), 'width' => 160),
       'Country' => array('title' => $this->l('Country'), 'width' => 160)

       );

       parent::__construct();

   }

And it works really nice. I see a grid with my distributors.

But then I added:

public function displayForm($isMainTab = true)
   {
       global $currentIndex;
       parent::displayForm();
       echo $this->className;
       $obj = $this->loadObject(true);

       echo ' tralala';

   } 

It's for displaying add and edit mode.


And the result is that:
echo shows ClassName: "Distributors",
but then I see nothing.

I realised, that function loadObject is in AdminTab.php
in line: ~1402

elseif ($opt)
       {
       echo 'Load3  ';
       echo $this->className;
           $this->_object = new $this->className();
           return $this->_object;
       }

I see "Load 3", and className: "Distributors"

there is something wrong with

$this->_object = new $this->className();

And I see on my add page nothing else.

I suppose that I should add some information about my table in any others files, or I did something wrong with mysql (auto_increment?)

Can someone help me.

I use PrestaShop 1.3.1.1 actualy on my local windows 7.

Please help me.

This is function LoadObject from AdminTab.php.

protected function loadObject($opt = false)
   {
       if ($id = intval(Tools::getValue($this->identifier)) AND Validate::isUnsignedId($id))
       {

           if (!$this->_object)
               $this->_object = new $this->className($id);
           if (!Validate::isLoadedObject($this->_object))
               die (Tools::displayError('object cannot be loaded'));
           return $this->_object;
       }
       elseif ($opt)
       {
       echo '1';
       echo $this->className;
           $this->_object = new $this->className();
       echo '2';
           return $this->_object;
       }
       else
       {
           die(Tools::displayError('object cannot be loaded'));
       }
   }

When I click "add new" I see "1" , "Distributors" (classname) but in the next line is some error.

Why?

className is correct, so why it does'nt want to create new object? Why it works correctly with other tables?

Maybe I didn't add some information in one of the php files? Something about my class? Should I do it somewhere?

Please help me. It's really important for me.

[adrub]

So, please try answer for this questions:

What exactly do this line: $this->_object = new $this->className(); ?

How does it know how to create new object with className - Distributors?

And what does it need to work correctly?

Hi,

I am also trying to create a module and therefore I am plunging into the working of PS (testsite is 1.3.7).

In your _construct method you are refering to

function __construct()
{

$this->table = 'distributors';
$this->className = 'Distributors';
$this->edit = true;
$this->delete = true;

When you instruct PS to create a object, it is looking for a file named "className.php" , in your case "Distributors.php" but only in the directory /classes!
else it gives you an error. At least that's what I found out.

Does anyone solve it? The classes doesnt help to me.

Hi there, I don't know you has the answer or not, but I would like to reply here for other people that have the same issue.

In AdminDistributors.php, add following function

 

function myautoload($className)
{
 $className = str_replace(chr(0), '', $className);
 $moduleDir = dirname(__FILE__).'/';
 $file_in_module = file_exists($moduleDir.$className.'.php');
 if ($file_in_module)
	 require_once($moduleDir.$className.'.php');
}

 

Then, at the end of your module constructor (in function __construct() ) add line:

$this->myautoload($this->className);

 

Now, you can load the class from your module dir.
