laravel-validation

问题 The validator in laravel can have a customization of the exists database rule, for instance if you need to check an extra column. An example from the manual: use Illuminate\Validation\Rule; Validator::make($data, [ 'email' => [ 'required', Rule::exists('staff')->where(function ($query) { $query->where('account_id', 1); }), ], ]); The query in the closure is not typehinted, so i'm not quite positive what kind of object this is. I can see that the DatabaseRule itself only has some function

问题 I'm not getting the response I expect. This is the controller code for a Location web-service request: <?php namespace App\Http\Controllers; use App\Location; use Illuminate\Http\Request; class LocationController extends Controller { /** * Action method to add a location with the supplied Data * * @param \Illuminate\Http\Request $p_oRequest Request * * @return JSON */ public function add(Request $p_oRequest) { try { $p_oRequest->validate( array( 'name' => 'required|alpha_num', 'user_id' =>

问题 I have three different forms on the same page. All inputs has it's own validation rules, code in Request file has structure like this: public function rules() { return [ // 'sold' => 'required', 'unit_in_stock' => 'required', 'unit_price_gbp' => 'required', 'returned_item' => 'required', ]; } public function messages() { return [ 'sold.required' => 'Please enter quantity of sold parts', 'unit_in_stock.required' => 'Please enter quantity of sold parts', 'unit_price_gbp.required' => 'Please

问题 I have come across an instance where I need to alter the data that needs to be validated i.e. when no slug has been submitted, create one from the title and then validate that it is unique. The request has a method replace() which is supposed to replace the input data on the request but it doesn't appear to work. Can anyone shine a light on this? This is what I have: <?php namespace Purposemedia\Pages\Http\Requests; use Dashboard\Http\Requests\Request; use Illuminate\Auth\Guard; class

问题 I am using cviebrock for validating image size in laravel. And thats working fine. But I want to customize the error message. I created an array of message $messages = array( 'image-size' => 'My custome message.', ); and passed to $validation = Validator::make(array($file => $fileObj), array($file => $rules), $messages); But thats not working. -Thanks Arun 回答1: You're using the wrong name, it should be with an underline, like $messages = array( 'image_size' => 'My custome message.', ); 来源：
