PHP Notice: Undefined variable: username

Everytime I go to any admin functions in the backend, I am getting the following error (error log) while in the admin panel of Opencart version 2.3.0.2

2016-09-08 9:29:19 - PHP Notice: Undefined variable: username in /home/sitename/public_html/storename/admin/view/template/common/column_left.tpl on line 5

Anyone know how to fix it?

I found an explanation in http://stackoverflow.com/questions/1917 ... n-opencart

Can I assume the following statement is correct;

PHP Notice: Undefined variable: username in
2016-09-08 12:53:35 - PHP Notice: Undefined variable: username in /home/sitename/public_html/storename/admin/view/template/common/column_left.tpl on line 5;

Here is line 5
<img src="<?php echo $image; ?>" alt="<?php echo $firstname; ?> <?php echo $lastname; ?>" title="<?php echo $username; ?>" class="img-circle" />

The reason why it's undefined is because it hasn't been set in the controller file first.

Opencart uses the MVC architecture, varibles are defined in the Controller, then used within the Template / View files. For this reason, it will always evaluate false using isset()

variable $username is not set,

to avoid this error use if(isset($username))

The code missing from the controller file (located: admin/controller/common/column_left.php) would be:

if(isset($username))
$this->data['username'] = $this->config->get('username');

Is this correct?

Your understanding in PHP is correct, however in this case, the issue needs to be fixed by updating the code Line no. 5 in admin/view/template/common/column_left.tpl as given below
The reason is variable $username is not defined in the controller file. Instead you can use the firstname lastname.

Code: Select all

<img src="<?php echo $image; ?>" alt="<?php echo $firstname; ?> <?php echo $lastname; ?>" title="<?php echo $firstname; ?> <?php echo $lastname; ?>" class="img-circle" />

The reason is variable $username is not defined in the controller file. Instead you can use the firstname lastname.

i was getting the same error in my 2.3.0.2 site and replaced the code as suggested by you.

Thanks
