In this post, I am going to explain how we can display the error on Admin Product controller custom form in our module.<\/p>\n
Step 1:-\u00a0 Changes in template form<\/strong><\/p>\n
Register the hook displayProductExtra<\/strong> and return the HTML<\/p>\n
Make sure you have added id=”form_hooks_{field_name}”<\/strong> in the form field where you want to display the error.<\/p>\n
Now check the condition whether there is an error or not.<\/p>\n
If there is an error then set the http_response_code with 400 and die the error.<\/p>\n
if ($this->context->controller->errors) {\r\n http_response_code(400);\r\n die(json_encode($this->context->controller->errors));\r\n}\r\n\r\n<\/pre>\n
<\/p>\n
This is how we can display the error message in the Admin Product controller custom form of our\u00a0module.<\/p>\n","protected":false},"excerpt":{"rendered":"
