Hello,

We have a module name pre-order for x-cart 5.3.3.1,
When i installed that module and after enabled i go to the product page at backend, then click on any product ad go to details page, There i find that A new tab "Preorder" is available. When i click on that tab then it's page are working but i have a problem that when i Click on "Product variant" Tab the it throw an error as below :

ERROR: "Includes\ErrorHandler::FATAL_ERROR" (code 2)
Call to a member function toArray() on null

and when i uninstalled preorder module that that "Product Variant" tab is working fine.


The code for the "Pre-order" module at path to call the preorder page is as below

classes/XLite/Module/Wevbkulsoftware/PreorderSales/Controller/Admin/Product.php

PHP Code:

/**
     * Page key
     */
    const PAGE_VARI = 'preorders';


public function getPages()
    {
        $list = parent::getPages();

        if (!$this->isNew()) {
            $list = array_merge(
                array_slice($list, 0, 5),
                array(static::PAGE_VARI => static::t('PreorderSales')),
                array_slice($list, 5)
            );
        }

        return $list;
    }



protected function getPageTemplates()
    {
        $list = parent::getPageTemplates();

        if (!$this->isNew()) {
            $list = array_merge(
                array_slice($list, 0,5),
                array(static::PAGE_VARI => 'modules/Webkulsoftware/PreorderSales/preorders/body.twig'),
                array_slice($list, 5)
            );
        }

        return $list;
    } 


And code for the module "Product variant" at path below
classes/XLite/Module/XC/ProductVariants/Controller/Admin/Product.php

is

PHP Code:

/**
     * Page key
     */
    const PAGE_VARIANTS = 'variants';
/**
     * Get pages
     *
     * @return array
     */
    public function getPages()
    {
        $list = parent::getPages();

        if (!$this->isNew()) {
            $list = array_merge(
                array_slice($list, 0, 2),
                array(static::PAGE_VARIANTS => static::t('Variants')),
                array_slice($list, 2)
            );
        }

        return $list;
    }

    /**
     * Get pages templates
     *
     * @return array
     */
    protected function getPageTemplates()
    {
        $list = parent::getPageTemplates();

        if (!$this->isNew()) {
            $list = array_merge(
                array_slice($list, 0, 2),
                array(static::PAGE_VARIANTS => 'modules/XC/ProductVariants/variants/body.twig'),
                array_slice($list, 2)
            );
        }

        return $list;
    } 


So, Please let me know the possible reason.

Hi @ajeetsingh,

Can you show backtrace for this fatal error? It should specify the file and exact line where toArray() method is called on null instead of object.

Thank you.

when i uninstalled preorder module that that "Product Variant" tab is working fine

.../Wevbkulsoftware/PreorderSales/...

I'm not sure, but it may be a bug in PreoredSales module.
Did you contact the module author?

Hi,

If the issue is from pre-order then can you please suggest me the reason of that issue. so that i will able to fix it.

[qualiteam]

Ah. I apologize. I missed the fact that you are from Webkul.

ERROR: "Includes\ErrorHandler::FATAL_ERROR" (code 2)
Call to a member function toArray() on null

This is not enough to guess why this may happen. Please check the log files in the var/log/ directory for the full text of the error message including the complete backtrace to the file and the line where it happens.

@ajeetsingh,

Judging by error messages in the log, there is a problem on 107 line in the classes/XLite/Module/Wevbkulsoftware/PreorderSales/Controller/Admin/Product.php file and I assume that the code you quoted earlier is correct:

/** 
     * Page key 
     */ 
    const PAGE_VARI = 'preorders'; 


public function getPages() 
    { 
        $list = parent::getPages(); 

        if (!$this->isNew()) { 
            $list = array_merge( 
                array_slice($list, 0, 5), 
                array(static::PAGE_VARI => static::t('PreorderSales')), 
                array_slice($list, 5) 
            ); 
        } 

        return $list; 
    } 



protected function getPageTemplates() 
    { 
        $list = parent::getPageTemplates(); 

        if (!$this->isNew()) { 
            $list = array_merge( 
                array_slice($list, 0,5), 
                array(static::PAGE_VARI => 'modules/Webkulsoftware/PreorderSales/preorders/body.twig'), 
                array_slice($list, 5) 
            ); 
        } 

        return $list; 
    }  

Could you please show the full code of that file?
