[SOLVED]Fatal error: Uncaught Error: Call to a member function write() on null in

Post by goksel1961 » Fri Apr 29, 2022 2:06 pm

Hello,
version 3038
Wrote a modification for /system/library/cart/car.php as follows:

Code: Select all

 <operation>
      <search><![CDATA[
    	$price = $product_special_query->row['price'];
      ]]></search>
      <add position="after"><![CDATA[
     	$special_price = $product_special_query->row['price'];
     	$this->log->write($special_price);
      ]]></add>
    </operation>
and get "Fatal error: Uncaught Error: Call to a member function write() on null in /var/www/storage/modification/system/library/cart/cart.php:193"
line 193 is $this->log->write($special_price);
And in error log:
2022-04-29 5:31:35 - PHP Notice: Undefined property: Cart\Cart::$log in /var/www/storage/modification/system/library/cart/cart.php on line 193
I use this log write function often. I suspected if it cannot be used in library classes but there is one in library/squareup/exception.php line 32 like this
$this->log->write($message);
I miss something but couldn find yet.
Would you please help? Thank you.

And its fixed , no errors anymore. But no log as well :D .
This is another case , I need to dig it sometime.
Cheers.

Code: Select all

    <operation>
      <search><![CDATA[
    	private $data = array();
      ]]></search>
      <add position="after"><![CDATA[
      private $log;
      private $registry;
      ]]></add>
    </operation>
    <operation>
      <search><![CDATA[
    	$this->weight = $registry->get('weight');
      ]]></search>
      <add position="after"><![CDATA[
        $this->log = $registry->get('log');
        $this->registry = $registry;
      ]]></add>
    </operation>

Thank you for your advice , i checked it out but as i mentioned before , $this ->log ->write is already used in squareup.php class in library. My current problem is
that i cant handle logs in system/library/cart.php with $this->log->write . No error but no log as well. I dont face that problem in catalog classes. I miss something.

I should've added without declaring registry and log.

The location doesn't look correct. The storage folder should be at the same level as the web root or under system. But that shouldn't stop the log being written.

Do you see any log file at all? Is it empty or just your messages not appearing? Have you tested you can log from a controller?

Ensure to move your storage folder along with the sub-folders outside of your www folder and edit both config.php files (DIR_STORAGE) accordingly. Then, ensure that recursive folder permissions (CHMOD) has been set (not on files) to 0755. File permissions should be set by default to: 0644 recursively.

Exactly. As I mentioned before, i can write log from anywhere in controller. Works perfectly. I cant write log only from library (cart.php) .

Just tested and I could log from system/library/cart/cart.php without any problems. Have you check the file in the modification folder to check it's correct? Are you using any other extensions that are modifying system/library/cart/cart.php or the calling of the cart functions?

Did you test it with $this->log = $registry->get('log'); declaration? mine should work too then but no log no error still.

Yes as shown attached image.
Are you using any other extensions that are modifying system/library/cart/cart.php or the calling of the cart functions?
No. Just this one. And the other modifications i made in this file work perfectly. Just writing logs. No error no logs.
And yes i call a cart function from a model class (getProducts) . And the modification i made in that function.

I moved the storage folder to var/ , Permissions set as you mentioned except cache folder. its 777. But no change . Still no error but no log.

Are you sure you are not using in a conditional statement?

Quickly test it by writing from the __construct method.

In system/library/cart/cart.php or if you are using ocmod try editing the cache file direct via storage/modification/system/library/cart/cart.php

In the __construct method

Below

Code: Select all

$this->weight = $registry->get('weight');
Add

Code: Select all

$this->log = $registry->get('log');
$this->log->write('LOG TEST');
Browse the frontend a few times and check the error log.

If that still doesn’t work, then something isn’t right with your setup, or you are editing the wrong files.

-

Backup and learn how to recover before you make any changes!
