Laravel validation with unique fields - php

Question

I have been trying unique validation in laravel 5.7. Below is my code for validation.
$this->validate($request, [
'name' => 'required|unique:permissions,name',
'slug' => 'required|unique:permissions,slug',
]);
And the html is below:
<div class='container'>
{!! Form::open(array('route' => 'permission.save','method'=>'POST')) !!}
<div class="row">
<div class="col-xs-12 col-sm-12 col-md-12">
<div class="form-group">
<strong>Name:</strong>
{!! Form::text('name', null, array('placeholder' => 'Name','class' => 'form-control')) !!}
</div>
<div class="form-group">
<strong>Slug:</strong>
{!! Form::text('slug', null, array('placeholder' => 'Slug','class' => 'form-control')) !!}
</div>
<div class="form-group">
<strong>Description:</strong>
{!! Form::textarea('description', null, array('placeholder' => 'Description','class' => 'form-control')) !!}
</div>
</div>
<div class="col-xs-12 col-sm-12 col-md-12 text-center">
<button type="submit" class="btn btn-primary">Submit</button>
</div>
</div>
{!! Form::close() !!}
</div>
Unique validation for 'name' is working fine but it is not working for 'slug'. It's really weird i can't get it. Please provide suggestions to fix this issue. Any help would be great.

Answer 1

You need to specify column name from database table in unique validation rule
https://laravel.com/docs/5.6/validation#rule-unique
for example your column name for slug is : column_slug
$this->validate($request, [
'name' => 'required|unique:permissions,name',
'slug' => 'required|unique:permissions,column_slug', // column_slug may be different in your case
]);
And ensure that you have set unique key for that column in database table
Hope it helps !
