How to count the total no of objects in array which I am receiving in $request. I had used count($request) or sizeOf($request) but its returning only 1 although there are 3 arrays. Help me in this.
How to save the data in database through such arrays.I want to save the values of input and input2.

Answer 1

Probably late, but may help someone in the future. First of all. You need to iterate over the array of objects like so
foreach($request->all() as $key => $value){
$model = new Model();
$model->attribute1 = $value['attribute1'];
$model->attribute2 = $value['attribute1'];
$model->attributeN = $value['attributeN']; // where N is infinite # of attr
$model->save();
}
So what is happening is that each time the loop iterates, it create a new object of your Model type inside the loop and assigns the objects attributes from the array key values and persists in DB and repeats until all the objects in the array are finished. The
$model = new Model();
is necessary so that each time loop iterates It creates a new object and persists. The loop may save only one object if u do not create it each time the N iteration occurs. This may happen if u are creating the model object in the constructor where it is instantiated once when the constructor is run.
Hope this helps.

Try to convert it to an array:
$data = json_decode($request, true);
$count = count($data); // Count number of elements.
Model::insert($data); // Insert all elements into DB.
Don't forget to validate any input first and add all fields except timestamps to a $fillable array.

Answer 3

You can try this..
$data = [{},{}]; // your response
$count = 0;
foreach($data as $obj)
{
Model::create($obj); //save the model
$count ++;
}
echo $count // your count

Answer 4

its quit simple
$request ='[ {"id":40,"cname":"Ramesh","constraint_value":"","r_id":"6","rtype_id":null,"deleted_at":null,"created_at":null,"updated_at":null,"input":"111","input2":"111"}, {"id":45,"cname":"Suresh","constraint_value":"","r_id":"6","rtype_id":null,"deleted_at":null,"created_at":null,"updated_at":null,"input":"222","input2":"222"}, {"id":49,"cname":"Raj","constraint_value":"","r_id":"6","rtype_id":null,"deleted_at":null,"created_at":null,"updated_at":null,"input":"333","input2":"333"}]';
$request = (array)json_decode($request, true);
now use them as you usually use .

I got the solution. I was making mistake in sending the data from angularjs.I was directly sending the POST request without creating its object like var data = { 'data':my_request} .That is why request was reeving with instance in laravel. But, as I start sending data by creating its object its working. This was the solution for my first problem. Help me how to store that received data in database.
