Error: Unrecognized variable design_json_data in Laravel Blade template

Frontend
1

I’m having problems with my Laravel project. When I load a page, an error appears:

Undefined variable: design_json_data (View: D:\xampp\htdocs\shopist\resources\views\pages\frontend\frontend-pages\frontend-designer.blade.php)

The issue seems to be with this line in my Blade template:

@include('pages.common.designer-html', array('designer_hf_data' => $designer_hf_data, 'designer_img_elments' => $single_product_details['_product_custom_designer_data'], 'design_save_data' => $design_json_data))

It works fine in the admin area, but not on the front-end. The page should allow users to add photos and text in a designer tool. Could anyone offer some guidance on how to resolve this error? I’m still learning Laravel and would appreciate any help.

The error typically occurs when a variable isn’t correctly passed from the controller to the view. In this case, check that your controller method is providing the variable by including it in your data array or using the compact function. For example, you should ensure that $design_json_data is included:

return view(‘your.view.name’, compact(‘designer_hf_data’, ‘single_product_details’, ‘design_json_data’));

If the variable isn’t needed on the front-end, you can avoid the error by using the null coalescing operator in your Blade template:

@include(‘pages.common.designer-html’, [
‘designer_hf_data’ => $designer_hf_data,
‘designer_img_elments’ => $single_product_details[‘_product_custom_designer_data’],
‘design_save_data’ => $design_json_data ?? null
])

This ensures that if $design_json_data is undefined, it defaults to null without crashing the view.

hmm, interesting issue sam! have u checked if the $design_json_data is actually needed for the frontend? if not, maybe u could just remove it from the include statement? or if u do need it, make sure its being passed correctly from the controller. whats the purpose of that variable in ur design anyway?

hey sam, i had a similar issue before. make sure ur passing the design_json_data variable to the view from ur controller. if its not needed for the frontend, u can use the ?? operator like this:

‘design_save_data’ => $design_json_data ?? null

that should fix the error without breaking anything. good luck!
