Override laravel validation message - php

Question

I am building a form which uploads multiple files ,its working fine but the problem is my validation message ,my validation is checking the mime type of the file .
suppose the uploaded file with name filename
The validation message :
The file.0 must be a file of type: pdf, doc, docx, jpeg, jpg, png, bnp.
i want to change it to
The filename must be a file of type: pdf, doc, docx, jpeg, jpg, png, bnp.
My form :
{!! Form::open(['route' => ['file.store'], 'method'=> 'POST', 'id' => 'file_form','files' => 'true']) !!}
{!!Form::FILE('file[]', ['id' => 'file','multiple' =>true])!!}
<button type="submit" name="submit">save</button>
{!! Form::close() !!}
my formRequest validation
foreach ($this->file as $key => $val)
{
$rules['file.' . $key] = 'mimes:pdf,doc,docx,jpeg,jpg,png,bnp|extension|max:10240'
}
return rules;

Answer 1

Hi if u are using the FormRequest to validate.
Thats how i achieved it.
Here is an example.
public function messages()
{
$messages = [];
foreach($this->request->get('items') as $key => $val)
{
$messages['items.'.$key.'.max'] = 'The field labeled "Book Title '.$key.'" must be less than :max characters.';
}
return $messages;
}

Use custom validation message
Add this line in custom array in validation.php inside resource/lang/en/ folder
'custom' => [
.........
'file.*' => [
'mimes' => 'The filename must be a file of type: :values.',
],
I recommend, rename file to unique_name to not conflict with name

I appropriate all of you for your answers,i have found another way that fits to my project. I have created custom validation called custom_mimes to validate file type based on mime type ,and adding custom replacer (:filename) to this validation.
\Validator::extend('custom_mimes', function ($attribute, $file, $parameters, $validator)
{
$validator->addReplacer('custom_mimes', function ($message, $attribute, $rule, $parameters) use ($file)
{
$values=implode(',',$parameters);
return str_replace([':filename',':values'], [$file->getClientOriginalName(),$values], $message);
});
$mime_type =$file->guessExtension();
return in_array($mime_type,$parameters);
});
and in validation.php
'custom_mimes' => 'The :filename must be a file of type: :values.',
so my key and values will be :
:filename => uploaded filename
:values =>'jpg,png,doc,docx'

Inside an Form Request you can simply use it like below:
public function messages()
{
$messages = [];
foreach($this->request->get('files') as $key => $val)
{
$messages['files.'.$key. ". max"] = 'The file field cannot be greater then 10M';
}
return $messages;
}
