CSRF on YAJRA datatable Laravel5.5 not working

Question

I have this code where I needed to store in a variable so I display it in view, I've tried different approach of packing the "Form header" and using CSRF is not working

$return = '<form method="post" action="/procurement/add-product">
    '.{{ csrf_token() }}.'
    <input type="hidden" name= "product_id" value=".$row->id.">
    <input type="text" name="product_qty"  class="form-control">
    <button type="submit" class="btn btn-primary btn-block">Add Item</button>
    </form>';

    return $return;

Here is my route

Route::post('/procurement/add-product','ProductController@addProcurementProduct');

Here is the JAvascript part

<script type="text/javascript">
$(function() {
    $('#procurement-table').DataTable({
        processing: true,
        serverSide: true,
        ajax: '{{ url('procurement/get_procurement_datatable') }}',
        columns : [
            {data: 'id', name: 'id'},
            {data: 'po_number', name: 'po_number'},
            {data: 'action', searchable: false, orderable: false},
            {data: 'created_at', name: 'created_at'},
            {data: 'updated_at', name: 'updated_at'}
        ]
    });
}); 
</script>

Answer 1

I've added missing hidden field csrf_token() which is require while submit and authorize form submission at laravel.

$return = '<form method="post" action="{{ action('ProcurementController@update', $details->id) }}">
    <input name="_token" type="hidden" value="{{ csrf_token() }}"><!--Added csrf missing field-->
    <input name="_method" type="hidden" value="PATCH">
    <input type="text" name="product_qty"  class="form-control">
    <button type="submit" class="btn btn-primary btn-block">Add Item</button>
    </form>';

You need to declare your action like this :

<form method="PUT" action="{{ route('product.update', $details->id) }}">

Check this : https://laravel.com/docs/5.4/controllers#resource-controllers

Maybe you will have to add the csrf_token to your form.

or you can do with Blade Form https://laravelcollective.com/docs/5.0/html :

{!! Form::open(array('url' => route('product.update', $details->id), 'method' => 'PUT') !!}
<input>
<input>
{!! Form::close() !!}

edit : You have to use PUT/PATCH method to your form (see the link about resource controllers)

Answer 3

Return the form to another blade like view/products/datatables.blade.php

Example: The controller should looks like:-

public function getproducts()
{
$product = Product::all(); //Product is Model name

return Datatables::of($product)
    ->addColumn('action', function($product)
    {
          return view('product.datatables', compact('product'))->render();
    })->make(true);

}

And the view should look as below:

<a href="{{ route('product.edit', ['$id' => $product->id]) }}" class="btn btn-success btn-sm">Edit</a>
<form action="/product/{{ $product->id }}" method="post" id="deleteForm">
    {{ method_field('DELETE') }}
    {{ csrf_field() }}
    <button class="btn btn-danger btn-sm" type="submit">Delete</button>
</form>

It will work just fine. Because the mustache {{}} can't be read in the controller. We redirect the things to the blade
