Without seeing the actual override file and knowing what you did, it is quite impossible to help you.

Same Error occured for me. I only wrote "HELLO" in AdminController to see whether it works or not, but everytime it shows same error..please help

Actually I am changing a query.... 

 

in function getList() of AdminController

 

** Actual Query

$this->_listsql = '

            SELECT SQL_CALC_FOUND_ROWS

            '.($this->_tmpTableFilter ? ' * FROM (SELECT ' : '');

 

**My Query

$this->_listsql = '

            SELECT DISTINCT SQL_CALC_FOUND_ROWS

            '.($this->_tmpTableFilter ? ' * FROM (SELECT ' : '');

 

This is done to restrict the view of orders in admin login for another user...

Well there are 1 of 3 things occuring

 

1) You are not creating the overrides properly.

2) .12 or .13 has changed the way overrides work and we will need to wait for Prestashop to document this

3) .12 or .13 has created yet again, more defects and broke how overrides work

 

To resolve

1) do your homework and read the documentation in the "Learn" menu. 

2) not much we can do but wait or try to figure it out

3) report your issue to Prestashop using their Forge and then wait and see

 

I suspect the issue is #3, but neither of you have provided your override classes, so I can't rule out #1

this fix might resolve your issues...but since ps does not update the released copies of 'current' 16013...it will happen until 'next' release

Hello Friends,

Finally Some changes in overriding behavior.

Overriding a class

In order to override the Product class, your file needs to be called Product.php and must feature a Product class that then extends ProductCore class.

The file can be placed in either of these locations:

• /override/classes/Product.php
• /modules/my_module/override/classes/Product.php

Overriding a controller

In order to override the ProductController class, your file needs to be called ProductController.php and must feature a ProductController class that then extends ProductControllerCore class.

The file can be placed in either of these locations:

• /override/controllers/front/ProductController.php
• /modules/my_module/override/controllers/front/ProductController.php

 

Even now you can override .tpl file of nay other module...

none of that is new information.  that is the way you override classes and controllers since they implemented overrides

Hello Bellini,

In Prestashop 1.6.0.9 it is possible to override core file without following this way of overriding, you can try put any core file in override folder of your module without making any change it will be overriden easily but in version 0.11, 0.12 and 0.13 it will not work in these versions you have to override file like this,

 

class AdminProductsController extends AdminProductsControllerCore

{

     ..

     ...

     ..

}

 

But problem is that it worked for me once when i installed it, after unintalling i tried to install it again now it is showing that old error.

"  Unable to install override: Class AdminProductsControllerOverride54ec51e02407e does not exist "

 

One more thing please try to override AdminProductsController without making any change it will throw you an error of bad sql query if it will be installed.

[bellini13]

you don't need to instruct me on how to create overrides.  My only point is that you are trying to document how overrides already work.  And this is already documented in the Prestashop developer's guide.  Nothing you have said is new.

 

If you have discovered a defect in .11, .12 and .13, then I would suggest you open a forge issue so that prestashop can review and fix the issue.  They do not read the forums...

I had a very similar issue / error as I was trying to install my first module that uses an override. For me, it turned out to be a simple fix: The naming of the class is very specific and must be correct. Working to override getPackageList method for exaple in Cart.php this worked:

class Cart extends CartCore
{
    public function getPackageList($flush = false)
    {
        parent::getPackageList();

The basic idea I think is that your class declaration for the class that you are overriding ends up being named the same as the file name, which obviously makes sense... but which is not the case if you've simply copied the original file over to the override folder as I'd done :-) since in that file the class is called CartCore.

In my case this error was for <?PHP declaration in my module controller, you must use <?php  

The issue is in classes/module/ModuleCore class in addOverride method at the line :

  eval(preg_replace(array('#^\s*<\?(?:php)?#', '#class\s+'.$classname.'\s+extends\s+([a-z0-9_]+)(\s+implements\s+([a-z0-9_]+))?#i'), array(' ', 'class '.$classname.'OverrideOriginal'.$uniq), implode('', $override_file))); 

eval code  fall when you use <?PHP or <?Php why preg_replace pattern is case sensitive.
