I want to get the value of my Select Dropdown list from my view to my controller

Is there any way i can get this? :(

Here's my dropdown view

{{ Form::select('status', ['All', 'Absent', 'Late', 'Others']) }}

Here's where i want to condition my selected value

    public function filterSummaryStudent()
    {
        if(Input::has('status') == 'All')
        {

      (other codes here)
         }

I've been getting a blank page when i call this.. Please help. Thank you!

    You must specify the value of select dropdown as associative arrays if you want to check the value as a string. Right now your select dropdown code the value is define using numeric index of the array. When you check the Input::has('status') == 'All', of course laravel will return false.

    Your code

    {{ Form::select('status', ['All', 'Absent', 'Late', 'Others']) }}
    

    HTML Output

    <select name="status">
        <option value="0">All</option>
        <option value="1">Absent</option>
        <option value="2">Late</option>
        <option value="3">Others</option>
    </select>
    

    Correct code

    {!! Form::select('status', ['All' => 'All', 'Absent' => 'Absent', 'Late' => 'Late', 'Others' => 'Others']) !!}
    

    HTML Output

    <select name="status">
        <option value="all">All</option>
        <option value="absent">Absent</option>
        <option value="late">Late</option>
        <option value="others">Others</option>
    </select>
    

    If you write like the above code you can check the select dropdown like this.

    if(Input::has('status') == 'All') {
        // Your code
    }
