To be serious, you should avoid the calling with AND without www
The error you have is based on this:

Quellübergreifende (Cross-Origin) Anfrage blockiert: Die Gleiche-Quelle-Regel verbietet das Lesen der externen Ressource auf http://www.beleza21.com/catalog/view/ja . f2?v=4.4.0. (Grund: CORS-Kopfzeile ‘Access-Control-Allow-Origin’ fehlt).

Hi Osworx, thanks for your reply.
Sometimes my browser auto-completes without the «www.». And then i get that error. I’m afraid my customers might see this error as well.

From your reply i didn’t quite get it how i can fix it? Could you be more accurate as to what the fix is?

Is this something that happens to everybody?

Fixing that can be done via 2 methods:

1. if you are using Plesk, simply define that there that you want URLs with / or without www (do not know if that can be done with other server panels like cPanel etc.)
2. simply add 2 lines to your .htaccess (either with or without www)

With both methods you are fine.

if i do that, i get the error all the time because it is without www. that i get the error.

i changed it to:

and now it is always www.beleza21.com and it works.

Important that it works.

While a ‘www’ is not really needed, it is just a subdomain technically.
So there is something else wrong.

Hello,
Thanks for your conversation and observations but seriously I got solution from here, as I read that this is going because of www and someone said that www. is a sub-domain and that strikes in mind that yes, a sub-domain can be a issue as in some CMS the file paths are used according to the installation directory and its URL and thus, creates an issue with most common sub-domain i.e. www.

Well, making a permanents re-direct without using www helps a lot in case site is installed on without www directory and vice-versa in case of if site is installed in with www directory.

Undefined variable error in OpenCart 3.x

Undefined variable error in OpenCart 3.x

Post by berdia » Tue Mar 23, 2021 8:58 pm

Hi,
I am getting:
Notice: Undefined variable: result in /var/www/storage/modification/catalog/controller/product/product.php on line 279;
Notice: Undefined variable: image in /var/www/storage/modification/catalog/controller/product/product.php on line 283
errors when I open individual products in OpenCart 3.x

Line 279 corresponds to this code: $images = $this->model_catalog_product->getProductImages($result[‘product_id’]);
Line 283 corresponds to this code: $images = $image;

This is a code in whole:

Could you please help to find out what the problem is?

Thanks for your reply.

OC version is 3.0.3.2
Most of the extensions are under Modules:
Account
Banner
Carousel
Category
Featured
HTML content
Information
Latest
Newsletters
Slideshow
Specials
Theme category type
onWebChat
PayPal Standard

We use a Theme which we bought from Templatemonster called Wined. http://www.templatemonsterpreview.com/demo/75072.html

P.S. I installed onWebChat last night and the problem was there before that so I presume onWebChat is not causing the issue.

Re: Undefined variable error in OpenCart 3.x

Above there seems to be a query (result): $result[‘product_id’]
But maybe it is not $result and the variable has another name.
Check the whole code.
Second message is a result of the missing first: $result[‘product_id’]

p.s.: Template Monster Templates are mostly full of bugs!
Therefore you should also contact them first before asking here for help, because the use a lot of own modules (most of them are a lousy copy of others) — and the whole thing is a commercial thing.

Common OpenCart Errors issues and How to Solve Them

This Opencart tutorial collects the most common errors that we face while developing and provides solutions for errors, try them and hope you could solve the issues

Cannot delete the admin folder in Opencart 4

https://forum.opencart.com/viewtopic.php?t=228495&p=843586 This solution looks working, for now, change the following lines of code at admin/controller/common/security.php

2. Blank White Pages or 500 Internal Server Error

Blank white pages are a PHP error that for some reason the error messages don’t show because your server is not set up to display the errors.

1. Go to the admin>> System >> Setting >> Edit store >> Server tab and at the end where you see the Error handling choose Yes to “Display Errors “.
2. If you still don’t see the error, open php.ini and add code below: display_errors = 1; error_reporting = E_ALL; log_errors = 1;
3. If you still don’t see the error then open index.php and add code below at the top (line 2): ini_set(‘display_errors’, 1); ini_set(‘log_errors’, 1); error_reporting(E_ALL);
4. Still seeing the error then, set your “Output Compression Level” to 0 in the System > Settings > Server tab.
5. If you still see the error, solve the issues but if you did not see the errors then most probably it will be a Server error.
6. You can see error logs in the file also if you had enabled it.

Above mostly it gets solved and the 500 Internal Server Error can be solved with a similar approach.

2. Undefined Index / Variable

An undefined variable in the source code of a computer program is a variable that is accessed in the code but has not been previously declared by that code. So for that using “isset()” to check if the variable has been set will solve the issue.

Error variant:

Notice: Undefined index: filter in /Applications/XAMPP/xamppfiles/htdocs/opencart303/catalog/controller/product/category.php on lin

Solution

• Commenting $filter = $this->request->get[‘filter’]; and checking with isset is one way to solve it.
• If you get the issue while installing the modules or extensions then you need to check the code or solve the issues or contacting the developer can be also another solution.

3. Undefined Function / Method

Undefined function/method errors are seen when you call those functions or methods that are not defined and not found. IE_ERROR: A fatal error that causes script termination “Fatal error: Call to undefined function” or “Fatal error: Call to undefined method”. It happens if files are not found or the extensions are not compatible with your OpenCart version. Solutions can be below:

Error variant:

Related to OpenCart core files

• Fatal error: Uncaught Error: Call to undefined method DBMySQLi::query()
• Fatal error: Uncaught Error: Call to undefined method CartCart::getProducts()
• Fatal error: Uncaught Error: Call to undefined method ControllerAccountLogin::validate() in …/catalog/controller/account/login.php:54

Go to the file and check whether the function or methods are defined there.

Error variant:

• Warning: Cannot modify header information – headers already sent by (output started at /public_html/config.php:31) in /path/public_html/index.php online.

Solution:

Remove spaces at the beginning and end of the file mentioned. Like in the above error check with the config.php

5. Session Issue

1. The product on the cart is self-cleared.
2. The product on the cart is cleared after the user logged in.
3. No items stored at product compares.
4. OpenCart admin always asking to login and get message “Invalid token session. Please log in again”.

Error variant:

• Warning: session_start () [function.session-start]: open (/tmp/…, O_RDWR) failed: No such file or directory (2) in /path/public_html/system /library /session.php on line

Solution:

No such file or directory issue

1. Open php.ini and add code below:session.save_path = /tmp;
2. If the solution above does not work, contact your host and ask them how to set session.save_path.

6. Allowed Memory Size Exhausted

This error happens because your memory is not enough to execute the PHP code (uploading large images, deleting a lot of products, sending mass emails, etc). Increasing the memory allocated for PHP will solve the issue.

Error variant:

• Fatal error: the Allowed memory size of 1111 bytes exhausted (tried to allocate 1111 bytes) in /path/public_html/system/library/image.php on line

Solution:

1. Edit php.ini and set memory_limit = 128M;
2. Or put code below to .htaccess php_value memory_limit 128M
3. If the above does not works then contacting the hosting providers is only the solution where they can increase the number.

Warning: Use of undefined constant DIR_STORAGE – assumed ‘DIR_STORAGE’ (this will throw an Error in a future version of PHP) in …/config.php on line

Some other errors that you can face are below:

Error: Calls to magic methods are not allowed!

Error: Could not call product/category

Error: Could not load model

Error: Could not load library

Error: Could not load helper

Error: Could not load cache adaptor Memcache/Redis/APC cache!

Error: Could not load database adaptor mpdo/mssql/mysql/mysqli/postgre !

Error: Could not make a database connection using this username and password

Error: Could not connect to database opencart

Error: PHP GD is not installed!

Error: Could not load image filename!

Error: Invalid session ID!

Warning: Install folder still exists and should be deleted for security reasons!

Installed bad extension, pressed refresh in the modification, and both admin panel and site are down

Remove it from the database, then open config.php and find what is the value defined for storage. Go to that storage/ folder, then go to modification and remove folders, similarly go to upload/ folder and see if there are folders if you have, remove it also. With this, it will remove the cached files and folder. Then, you can access your admin again.

Fatal error uncaught exception

Fatal error: Uncaught Exception: Error: Table ‘….oc_session’ doesn’t exist in engine
Error No: 1932
SELECT `data` FROM `oc_session` WHERE session_id = ‘….’ AND expire > 1548638620 in …/system/library/db/mysqli.php:40 Stack trace: #0 …/system/library/db.php(45): DBMySQLi->query(‘SELECT `data` F…’) #1

For these errors to solve creating a database table will solve most of the issues

Fatal error: Uncaught Exception: Error: Could not load database adaptor DB_DRIVER!

Check in the system/library/DB folder whether the required driver file is there.
