//ajax
$(document).on("click", ".agent-add", function () {

    var agent_id = $(this).data('id');

    $('form').submit(function(event) {
        event.preventDefault();
        $.ajax
        ({
            url: '{{ url('/agents') }}',
            type: 'POST',              
            data: {
                "_method": 'POST',
                "name": $('input[name=name]').val(),
                "email": $('input[name=email]').val(),
                "phone_number": $('input[name=phone_number]').val(),
                "address_city_village": $('input[name=address_city_village]').val(),
                "address_state": $('input[name=address_state]').val(),
                "image": $('input[name=image]').val(),
                "password": $('input[name=password]').val()
            },
            success: function(result)
            {
                location.reload();
            },
            error: function(data)
            {
                console.log(data);
            }
        });

    });
}); 

my controller is

public function store(Request $request)
{
    if (User::where('phone_number', '=', Input::get('phone_number'))->exists()) {
       return $this->respondBadRequest('Phone Number Exists');
    }
    else 
    {
        User::create($request->all());

        return redirect('agents')->with('Success', 'Agent Added');

        if($request->hasFile('image')) {
            $file = $request->file('image');

            //you also need to keep file extension as well
            $name = $file->getClientOriginalName().'.'.$file->getClientOriginalExtension();

            //using array instead of object
            $image['filePath'] = $name;
            $file->move(public_path().'/uploads/', $name);

        }
    }
}

i guess i'm missing something in ajax posting , but i couldn't figure it out

i dd($request->all());

the result is

array:9 [▼
  "_token" => "heSkwHd8uSIotbqV1TxtAoG95frcRTATgeGL0aPM"

Answer 1

Try using the FormData in ajax while you upload a file.

Just try this

$('form').submit(function(event) {
    event.preventDefault();
    var formData = new FormData($(this)[0]);
    $.ajax({
        url: '{{ url('/agents') }}',
        type: 'POST',              
        data: formData,
        success: function(result)
        {
            location.reload();
        },
        error: function(data)
        {
            console.log(data);
        }
    });

});

OR

You can try with this jQuery library

https://github.com/malsup/form

EDIT

public function store(Request $request)
{
    if (User::where('phone_number', '=', Input::get('phone_number'))->exists()) {
       return $this->respondBadRequest('Phone Number Exists');
    }
    else 
    {
        $user=User::create($request->all());

        if($request->hasFile('image')) {
           $file = $request->file('image');

           //you also need to keep file extension as well
           $name = $file->getClientOriginalName().'.'.$file->getClientOriginalExtension();

           //using the array instead of object
           $image['filePath'] = $name;
           $file->move(public_path().'/uploads/', $name);
           $user->image= public_path().'/uploads/'. $name;
           $user->save();
        }
        return redirect('agents')->with('Success', 'Agent Added');
    }
}

Answer 2

Try something like this:

$('#upload').on('click', function() {
        var file_data = $('#pic').prop('files')[0];
        var form_data = new FormData();
        form_data.append('file', file_data);

        $.ajax({
                url         : 'route_url',
                dataType    : 'text',           // what to expect back from the PHP script, if anything
                cache       : false,
                contentType : false,
                processData : false,
                data        : form_data,                         
                type        : 'post',
                success     : function(output){
                    alert(output);              // display response from the PHP script, if any
                }
         });
    });

Answer 3

Just me or does your <input type="file"> not have a "name" attribute? Therefore the server is not receive the file data from the post?

EDIT:

After you insert the record into the database, you then handle the file uploading - but you never then update the record with the files name.

*Just confirm that the file was uploaded.

Answer 4

name attribute not set for the file type input. May be?

Answer 5

I will explain using a simple example.

HTML:

<form id="header_image_frm" method="POST" action="">
    <input type="file" name="header_image" id="header_image" value="Upload Header Image">
</form>

JS: (Properties of ajax called contentType, processData must)

<script>
  $(document).ready(function() {
    $('#header_image').change(function() {
        let formData = new FormData($('#header_image_frm')[0]);
        let file = $('input[type=file]')[0].files[0];
        formData.append('file', file, file.name);
        $.ajax({
            url: '{{ url("/post/upload_header") }}',
            headers: {'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')},
            type: 'POST',   
            contentType: false,
            processData: false,   
            cache: false,        
            data: formData,
            success: function(data) {
                console.log(data);
            },
            error: function(data) {
                console.log(data);
            }
        });
    });
  });
</script>

Laravel / PHP:

public function upload(Request $request) {
  if ($_FILES['file']['name']) {
    if (!$_FILES['file']['error']) {
        $name = md5(rand(100, 200));
        $ext = explode('.', $_FILES['file']['name']);
        $filename = $name . '.' . $ext[1];
        $destination = public_path() . '/images/' . $filename;
        $location = $_FILES["file"]["tmp_name"];
        move_uploaded_file($location, $destination);
        echo '/images/' . $filename;
    } else {
        echo = 'Ooops!  Your upload triggered the following error:  '.$_FILES['file']['error'];
    }
  }
}
