unique validation error while updating using form request

[AjithLalps]

I form for saving the category. The name field is unique. I'm using FormRequest for validating the form. Create works fine. but while updating getting error showing The name.en has already been taken.

form fields

                <input class="form-control" name="name[en]" type="text" id="name-en" value="{{ old('name[en]', optional($serviceCategory)->getTranslation('name','en')) }}" minlength="1" maxlength="255" placeholder="{{ __('preferencesCategory.name_en__placeholder') }}">
                <input class="form-control" name="name[ar]" type="text" id="name-ar" value="{{ old('name[ar]', optional($serviceCategory)->getTranslation('name','ar')) }}" minlength="1" maxlength="255" placeholder="{{ __('preferencesCategory.name_ar__placeholder') }}">

FormRequest.php

  public function rules()
    {
        return [
            'code' => 'string|min:1|nullable',
            'name.*' => 'required|string|min:1|max:255|unique_translation:service_categories,name,{$this->serviceCategory->id}',
            'status' => 'string|min:1|nullable',
        ];

web.php (route file)

Route::put('service_category/{serviceCategory}', 'ServiceCategoriesController@update')
            ->name('service_categories.service_category.update')->where('id', '[0-9]+');

controller.php

public function update(ServiceCategory $serviceCategory, ServiceCategoriesFormRequest $request)
    {
        try {
            $data = $request->getData();
            $data['updated_by'] = \Auth::guard('admin')->user()->id;

            $serviceCategory->update($data);

            return redirect()->route('service_categories.service_category.index')
                ->with('success_message', 'Service Category was successfully updated.');
        } catch (Exception $exception) {
            return back()->withInput()
                ->withErrors(['unexpected_error' => 'Unexpected error occurred while trying to process your request.']);
        }
    }

Hi,

Before I start bug hunting: any chance it has something to do with using {$this->serviceCategory->id} within single quotes instead of double quotes?

If not, I'll try to reproduce it in a test. 👍

like this 'name.*' => 'required|string|min:1|max:255|unique_translation:service_categories,name,' . '{$this->serviceCategory->id}',?

It worked after updating the rule,route and function like below.
FormRequest

'name.*' => 'required|string|min:1|max:255|unique_translation:service_categories,name,' . $this->id,

web.php(route file)

Route::put('service_category/{id}', 'ServiceCategoriesController@update')
            ->name('service_categories.service_category.update')->where('id', '[0-9]+');

controller

public function update($id, ServiceCategoriesFormRequest $request)
{
....
}

but why your example not working?

Hi,

In PHP you can do this:

$str = "A string containing a {$variable}";

But not this (single quotes around the string):

$str = 'A string containing a {$variable}';

So this should work for you:

'name.*' => "required|string|min:1|max:255|unique_translation:service_categories,name,{$this->serviceCategory->id}",
