Get data from multiple forms Laravel

Question

I am working on Laravel. I have a blade view page on which multiple forms (of same model) are created. Now, I want, that when I click submit button, an array of all the forms should be returned to controller. But, it returns data of only one form instead of array. How can I achieve this, Can anyone help me?

Answer 1

It's not a real Laravel issue.

The trick is using different forms with each a submit button. Then, it's simple. Check the submitted button.

if ($request->isMethod('post')) {

    if ($request->has('submit_button_form_1')) {
        // Handle form
    }
    elseif ($request->has('submit_button_form_2')) {
        // Handle form
    }
    elseif ($request->has('submit_button_form_3')) {
        // Handle form
    }
}

What you can do is you need to loop the form field with naming structure as first_name1, first_name2 and so on. Then, after submitting the form, you can validate using the loop in the same way and get the values. You can check my sample code here. It count the number of loops to be made.

You can pass the counter from the view to the controller in hidden field. Then, you can loop for validation and for taking the inputs.

Check my sample code:

//determine number of rows in database
        $number_of_loop = Input::get('number_of_loop');

        $arrayList = []; //defining the array variable

        //declaring the validations rules
        for($i = 1; $i < $number_of_loop; $i++){
            $rules = array(
                'currency'.$i   => 'required',
                'iso_code'.$i   => 'required',
                'symbol'.$i     => 'required',
                'status'.$i     => 'required'
            );
            $validator = Validator::make(Input::all(), $rules);

            if($validator->fails()){

                return Redirect::back()->withErrors($validator)->withInput();
            }
        }

        for ($i=1; $i <= $number_of_loop; $i++) {

            $new_currency = new stdClass();

            $currency = Input::get('currency' . $i); 
            $iso_code = Input::get('iso_code'.$i);
            $symbol = Input::get('symbol'.$i);
            $conversion_rate = Input::get('conversion_rate'.$i);
            $status = Input::get('status'.$i);


            $new_currency->currency = $currency; 

            $new_currency->iso_code = $iso_code; 

            $new_currency->symbol = $symbol; 

            $new_currency->conversion_rate = $conversion_rate; 

            $new_currency->enable = $status; 

            array_push($arrayList, $new_currency);


        }

Update1

For storing all the records, create an array and a new stdclass. Store all the variable in stdclass attributes. and at last, push the new stdclass to the array. Then, you can access all the inputs of form. Check above updated code sample

First of all I dont think you can send multiple forms, that is just way it is. You have two options.

First: Make one form with all fields from all forms, and then in controller you just take what field you want, just like you would do from arrays so same thing. Like:

$all_fields= Request::all();
and then 
$all_fields['something'], $all_fields['something_else'],

Second: Using ajax, you can manipulate and send values of fields, fields that you need.

If you’re using Laravel 5.2 then you can validate array data. You’ll need to put all of your inputs in one form as you just can’t send multiple forms. If each form had different URLs for the action attribute, how would that work?

To send data as an array, you can suffix the name attribute with []:

{!! Form::open() !!}
{!! Form::text('name[]') !!}
{!! Form::text('name[]') !!}
{!! Form::text('name[]') !!}
{!! Form::close() !!}

When this form is submitted, name will be an array with three elements.

To validate, use a wildcard in your validation rule name:

return [
    'name.*' => 'required|max:255',
];

You can then access the array of names in your controller through the Request object:

$names = $request->get('names', []);

foreach ($names as $name) {
    User::create(['name' => $name]);
}

I don’t know your data structure as you haven’t included it in your question, but this should be enough for you to apply to your given scenario.
