Laravel validate incoming ajax using request - ajax

Question

I have a view like this:
// snippet of view
<td><input class="form-field" type="text" id="entity" name="name" data="{{$entity->id}}" value="{{$entity->name}}" onkeyup="validation(this.value);" onblur="updateEntity(this.value,this.name,this.id,{{$entity->id}})"></td>
<td><input class="form-field" type="text" id="entity" name="type" value="{{$entity->type}}" onkeyup="validation(this.value);" onblur="updateEntity(this.value,this.name,this.id,{{$entity->id}})"></td>
Which has an ajax:
function updateEntity(value, name, data, id) {
$.ajax({
url: '/entityadmin/' + value + '/' + name + '/' + data + '/' + id,
method: 'POST',
dataType: 'json',
success: function(save) {
$('.messages').append('<div class="alert alert-success">Type Updated!<div>');
setTimeout(function() {
$(".alert").fadeTo(2000, 500).slideUp(500, function(){
$(".alert").slideUp(500);
});
}, 4000);
},
error: function(data) {
console.log(data);
$('.messages').append('<div class="alert alert-danger">Error, please try again!<div>');
setTimeout(function() {
$(".alert").fadeTo(2000, 500).slideUp(500, function(){
$(".alert").slideUp(500);
});
}, 4000);
},
headers: {
'X-CSRF-Token': $('meta[name="csrf-token"]').attr('content')
}
});
}
Controller:
public function entityUpdate($value, $name, $data, $id, EntityRequestUpdate $request) {
$request->$name = $value; //like this?
if($data == "entity") {
$save = Entity::find($id);
}else{
$save = User::find($id);
}
$save->$name = $value;
$save->save();
return response()->json(['results' => $save]);
}
and request:
public function rules()
{
return [
'startdate' => 'required|date',
'endate' => 'nullable|date',
'startime' => 'required|time',
'endtime' => 'required|time',
'title' => 'required',
'type' => 'required',
'description' => 'required',
'frequency' => 'required',
'interval' => 'nullable|numeric',
'monthday' => 'nullable|numeric|min:1|max:3',
'weekday' => 'nullable|alpha|max:3',
'month' => 'nullable|numeric',
'until' => 'nullable|date',
'tags' => 'nullable',
'img' => 'nullable|file|image',
];
}
The thing is it only has to validate one field because one field is being changed each time, how can I use this validation to validate the incoming variable and return errors to ajax with the message on the error if there is any?

Answer 1

You can manually create a validator to validate this one field like so:
$validator = Validator::make(
[ 'name' => $value ],
collect($this->rules())->only([$name])->all()
);
This validator will take the name validator from the defined rules and check that against the first array of values.
