I am trying to validate parameters with Json-RPC. With Symfony2 validation I can do this:
$expense = new Expense;
$expense->setAmount(1);
$validator = $this->get('validator');
$errors = $validator->validate($expense);
But I do not want to manually specify each parameter with the setFoo() method. Is there anyway to bind the data similar to how the Symfony Form library works?
If I understand your question, $errors = $validator->validate($user) will do the job. See using the validator service documentation.
Turns out this is not possible with Symfony2. You will have to bind the data yourself. I created a bind method similar to this:
$params = array('amount' => 1);
foreach($params as $key => $value) {
try {
$path = new PropertyPath($key);
$path->setValue($obj, $value);
} catch (\Exception $e) {
// parameter does not exist in POPO
}
}
After you bind your parameters to the POPO object, you can validate it normally.

I have a function to add new property. But i want to check for duplicate data at column "code" before add new data into database. If data exists will appear a message error.
function addPro(Request $req)
{
$id = $req->type_id;
$type = AssetType::find($id);
if($req->save == 'save'){
$pro = new TypeProperties;
$pro->name = $req->name;
$pro->code = $req->code;
$pro->type = $req->type;
$pro->assettype_id = $req->type_id;
$pro->save();
Schema::table($type->code, function ($table) use ($pro) {
if ($pro->type == "textbox")
$table->string($pro->code )->nullable();
if ($pro->type == "textarea")
$table->text($pro->code )->nullable();
});
return redirect(url($type->id.'/add/property'))->with('message','Save successful');
}
return redirect(url('asset/type/'.$type->id));
}
You can use laravel Request Validation
function addPro(Request $req)
{
$id = $req->type_id;
$type = AssetType::find($id);
if($req->save == 'save'){
$req->validate([
'code' => 'required|unique:tablename'
]);
$pro = new TypeProperties;
$pro->name = $req->name;
$pro->code = $req->code;
$pro->type = $req->type;
$pro->assettype_id = $req->type_id;
$pro->save();
Schema::table($type->code, function ($table) use ($pro) {
if ($pro->type == "textbox")
$table->string($pro->code )->nullable();
if ($pro->type == "textarea")
$table->text($pro->code )->nullable();
});
return redirect(url($type->id.'/add/property'))->with('message','Save successful');
}
return redirect(url('asset/type/'.$type->id));
}
The most simple way to do this is by checking if code is_null :
if (is_null($pro->code)) {
// It does not exist
} else {
// It exists
}
The other way is to make a validation using Laravel's built in ValidateRequest class. The most simple use-case for this validation, is to call it directly in your store() method like this:
$this->validate($req, [
'code' => 'required|unique,
//... and so on
], $this->messages);
With this, you're validating users $req by saying that specified columns are required and that they need to be unique, in order for validation to pass. In your controller, you can also create messages function to display error messages, if the condition isn't met:
private $messages = [
'code.required' => 'Code is required',
'code.unique' => 'Code already exists',
//... and so on
];
You can also achieve this by creating a new custom validation class:
php artisan make:request StorePro
The generated class will be placed in the app/Http/Requests directory. Now, you can add a few validation rules to the rules method:
public function rules()
{
return [
'code' => 'required|unique,
//... and so on
];
}
All you need to do now is type-hint the request on your controller method. The incoming form request is validated before the controller method is called, meaning you do not need to clutter your controller with any validation logic:
public function store(StorePro $req)
{
// The incoming request is valid...
// Retrieve the validated input data...
$validated = $req->validated();
}
If you have any additional question about this, feel free to ask. Source: Laravel official documentation.
What does your migration look like for AssetType?
I ask because you can do this in the schema with ->unique() added to the column on the creation or make a migration to add the constraint.
You can also check with something like this:
// Search database table for entry
$entry = AssetType::where('code', '=', $pro->code)->first();
// If not found
if ($entry === null) {
// Save method here.
}
Otherwise, you can use the manual validator or create a Request with validation

I have the following code which sends a passowrds recovery mail:
public function recovery(Request $request)
{
$validator = Validator::make($request->only('email'), [
'email' => 'required'
]);
if($validator->fails()) {
throw new ValidationHttpException($validator->errors()->all());
}
$response = Password::sendResetLink($request->only('email'), function (Message $message) {
$message->subject(Config::get('boilerplate.recovery_email_subject'));
});
switch ($response) {
case Password::RESET_LINK_SENT:
return $this->response->noContent();
case Password::INVALID_USER:
return $this->response->errorNotFound();
}
}
Which I found out uses the following template: resources/views/auth/emails/password.php
which is an empty file.
How I can access the token from this template?
Isn't there any built-in view to use from laravel?
The function in your questions doesn't return a view.
Also, I'm unfamiliar with that path to the view that is in your question. Which version of Laravel are you using?
Anyhow, you can get the reset token from the DB, just like any other value in the DB. E.g. from a controller that is returning a view:
$user = User::find(Auth::id());
$remeber_token = $user->remember_token;
return view('to_your_view.blade.php', compact('remember_token');
And then in the view file:
{{ $remember_token }}
This will output it, no need to use echo or anything.
But, again, the function you pasted into your question is not a function that is returning a view, so I'm not sure where to tell you to put the above code.
As for your questoin about Laravel having an in-built view for 'this', in Laravel 5.3, at least, the view I assume you want will be within `resources/views/auth/passwords/'.
I need to change value of my request parameter like this:
$request->name = "My Value!";
I use this code but does not work:
$request->offsetSet('img', $img);
Try to:
$requestData = $request->all();
$requestData['img'] = $img;
Another way to do it:
$request->merge(['img' => $img]);
Thanks to #JoelHinz for this.
If you want to add or overwrite nested data:
$data['some']['thing'] = 'value';
$request->merge($data);
If you do not inject Request $request object, you can use the global request() helper or \Request:: facade instead of $request
Use merge():
$request->merge([
'user_id' => $modified_user_id_here,
]);
Simple! No need to transfer the entire $request->all() to another variable.
Read more about Laravel's merge() here:
https://laravel.com/docs/collections#method-merge
If you need to customize the request
$data = $request->all();
you can pass the name of the field and the value
$data['product_ref_code'] = 1650;
and finally pass the new request
$last = Product::create($data);
If you need to update a property in the request, I recommend you to use the replace method from Request class used by Laravel
$request->replace(['property to update' => $newValue]);
Use add
$request->request->add(['img' => $img]);
If you use custom requests for validation, for replace data for validation, or to set default data (for checkboxes or other) use override method prepareForValidation().
namespace App\Http\Requests\Admin\Category;
class CategoryRequest extends AbstractRequest
{
protected function prepareForValidation()
{
if ( ! $this->get('url')) {
$this->merge([
'url' => $this->get('name'),
]);
}
$this->merge([
'url' => \Str::slug($this->get('url')),
'active' => (int)$this->get('active'),
]);
}
}
I hope this information will be useful to somebody.
It work for me
$request = new Request();
$request->headers->set('content-type', 'application/json');
$request->initialize(['yourParam' => 2]);
check output
$queryParams = $request->query();
dd($queryParams['yourParam']); // 2
Great answers here but I needed to replace a value in a JSON request. After a little digging into the code, I came up with the following code. Let me know if I'm doing something dumb.
$json = $request->json()->all();
$json['field'] = 'new value';
$request->json()->replace($json);
Try that :
$request["name"] = "My New Value";
$request["img"] = $img;
It's worked in Laravel 8.
Also, make sure to update the model class.
Item
{
fillable=[
'img',
... // other attributes
];
}
in case of updating an item of object you can write the lines bellow
$Obj = $request->data;
$Obj['item'] = value;
I tried googling and saw other questions posted at this forum but could not find any solution for my issue. I am using Jquery ajaxForm method to submit form. My form contains one file field too in the form that can be used to upload a picture. I have defined the validation in my model. But the issue is even i am uploading a correct jpg file, still i am getting error message that
Argument 1 passed to Illuminate\\Validation\\Factory::make() must be of the type array, object given.
Javascript Code
$('#create_form').ajaxForm({
dataType:'JSON',
success: function(response){
alert(response);
}
}).submit();
Controllder Code
if ($file = Input::file('picture')) {
$validator = Validator::make($file, User::$file_rules);
if ($validator->fails()) {
$messages = $validator->messages();
foreach ($messages->all(':message') as $message) {
echo $message; exit;
}
return Response::json(array('message'=>$response, 'status'=>'failure'));
} else {
// do rest
}
}
Model Code
public static $file_rules = array(
'picture' => 'required|max:2048|mimes:jpeg,jpg,bmp,png,gif'
);
POST Request
I know that my validation defined in the model expects an array. But by passing $file in the validator, an object is passed. Then i changed the code like:
$validator = Validator::make(array('picture' => $file->getClientOriginalName()), User::$file_rules);
Now i am getting error:
The picture must be a file of type: jpg, JPEG, png,gif.
The problem is you pass file object directly to validate. Validator::make() method takes all four parameters as array. Moreover, you need to pass the whole file object as value so that Validator can validate mime type, size, etc. That's why your code should be like that.
$input = array('picture' => Input::file('picture'));
$validator = Validator::make($input, User::$file_rules);
if ($validator->fails()) {
$messages = $validator->messages();
foreach ($messages->all(':message') as $message) {
echo $message; exit;
}
return Response::json(array('message'=>$response, 'status'=>'failure'));
} else {
// do rest
}
Hope it will be useful for you.
Try rule like this.
$rules = array(
'picture' => 'image|mimes:jpeg,jpg,bmp,png,gif'
);
or try removing 'mimes'
I have a problem related to CActiveForm::validate(). I have a form and and sending data to database using Ajax, my form contains a multiple selectable drop-down list. In data saving section of controller produced the following error initially
mb_strlen() expects parameter 1 to be string, array given (.../framework/validators/CStringValidator.php:84)
and after updating framework to newer version, that error gone, and got the below validation message instead.
Category Ids is invalid.
If the form is fully filled(I mean all the rules in the model satisfied), it will not produce any such bug or error message.
controller action
public function actionCompany() {
$model = new Company;
if (isset($_POST['Company'])) {
$model->attributes = $_POST['Company'];
$category_ids = "";
if (is_array($_POST['Company']['category_ids']))
$category_ids = implode(',', $_POST['Company']['category_ids']);
$model->category_ids = $category_ids;
if ($model->validate()) {
/*$temp = Company::model()->findByPK($model->id);
if ($temp !== null) {
$model = $temp;
}*/
$model->save();
echo CJSON::encode(array('status' => 'success'));
Yii::app()->end();
} else {
$error = CActiveForm::validate($model);
if ($error != '[]')
echo $error;
}
}
}
Model rules
public function rules()
{
return array(
array('...., category_ids,...', 'required'),
array('..., category_ids, ...', 'length', 'max'=>255),
....
.....
array('...., category_ids,...', 'safe', 'on'=>'search'),
);
}
What is actually I'm missing?
By default, CActiveForm::validate($model) loads the model attributes from $_POST and overrides current attribute values, thus destroying your transformed values. Pass false as the third argument to avoid this.
