Question

我的更新方法工作不幸的是它总是更新错误的数据，在这种情况下，它总是更新我的数据库列表中的最后一个数据。我相信这是因为我的模态框指向$ user-＆gt; id，它总是指向最后一个id，因为我在顶部使用了for循环，有没有办法将它指向所选的id而不是？

view.blade.php

    public void pickImageOnClick(View view){
        shouldSwitch = false;

        //startActivityForResult(i, PHOTO_FROM_MEMORY_REQUESTED); 
        Intent localIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        localIntent.setType("image/*");
        localIntent.setAction(Intent.ACTION_GET_CONTENT);
        localIntent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
        startActivityForResult(localIntent, PHOTO_FROM_MEMORY_REQUESTED);
    }

    private File createGameFile(String part, String ext) throws Exception
    {
        //Getting external storage path, and .temp directory in it.
        File mainDir= Environment.getExternalStorageDirectory();
        mainDir=new File(mainDir.getAbsolutePath()+MAIN_FOLDER);

        //If .temp does not exists, it is created.
        if(!mainDir.exists()) mainDir.mkdir();       

        return new File(mainDir.getAbsolutePath().toString(), part+ext);
       // return File.createTempFile(part, ext, mainDir);

    }

    public void playOnClick(View View){
        Intent intent = new Intent(this, PuzzleActivity.class);
        String[] gameSizes = getResources().getStringArray(R.array.gamesizes);
        intent.putExtra(EXTRA_GAMESIZE, gameSizes[gameSizeSpinner.getSelectedItemPosition()]);
        intent.putExtra(EXTRA_IMGURI, imageUri);
        //Toast.makeText(getApplicationContext(), "Hi"+imageUri, 400).show();
        int orientation;    //Determining screen orientation.
        orientation = (selectedImage.getWidth()>selectedImage.getHeight()) ? 
                GameBoard.ORIENTATION_HORIZONTAL : GameBoard.ORIENTATION_PORTRAIT;
        intent.putExtra(EXTRA_BOARD_ORIENTATION, orientation);

//      String str = orientation == 0 ? "PORTRAIT" : "HORIZONTAL";
//      Log.d("KAMIL", "Orientation : " + str);

        shouldSwitch = true;
        startActivity(intent);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {

        if(requestCode == PHOTO_FROM_MEMORY_REQUESTED && resultCode == RESULT_OK){
            //updateSelectedPicture(data.getData());
            try
            {
            imageUri = data.getData();
            //scaleImage(uri, 2048);

            BitmapFactory.Options options=new BitmapFactory.Options();
            options.inSampleSize = 9;

            //Opening the input stream and receiving Bitmap.
            InputStream imageStream = getContentResolver().openInputStream(imageUri);
            //selectedImage = BitmapFactory.decodeStream(imageStream);
            selectedImage = BitmapFactory.decodeStream(imageStream,null,options);
            //.selectedImage = BitmapFactory.decodeFile(i);
            //Bitmap thumbnail = BitmapFactory.decodeFile(mFileTemp.getPath());
            if (selectedImage.getHeight() > 1200)
                selectedImage = Bitmap.createScaledBitmap(selectedImage, selectedImage.getWidth() * 1200 / selectedImage.getHeight(), 1200, false);
            //Toast.makeText(getApplicationContext(), ""+selectedImage.getHeight(), 400).show();
            System.gc();
            playButton.setEnabled(true);
            }
              catch (FileNotFoundException localFileNotFoundException)
              {
                localFileNotFoundException.printStackTrace();
              }
        }

Answer 1

你的模态是引用$ user对象，但它不在你的foreach循环中。

特别是这一行：

<form class="form-horizontal" role="form" action="/manage_accounts/{{ $user->id }}" novalidate>

您可以为模态弹出按钮注册onClick事件，该按钮会抓取用户ID的隐藏输入字段并动态更新操作URL。或者，您可以让操作URL相同并处理逻辑服务器端。这种方法将为您要更新的用户ID提供隐藏的输入字段，但处理URL结构要清晰得多。

Javascript示例：

<script type="text-javascript">
                    $(function() {
                      $('.btn--edit').on('click', function() {
                        var formAction = $('.form-horizontal').attr('action').replace(/(?!.*/).*, '');
                        var userId = $(this).closest('[name=user_id]').val();
                        $('.form-horizontal').attr('action', formAction + '/' + userId);
                      });
                    });
                    </script>

这要求您更新类名为.btn - edit

的模态按钮

<button class="btn btn-sm btn-warning btn--edit" type="button" data-toggle="modal" data-target="#form">Edit&nbsp;<i class="glyphicon glyphicon-edit"></i></button>

这也要求你在foreach的某个地方添加一个隐藏的输入。我选择了用户信息类。

<input type="hidden" name="user_id" value="{{ $user->id }}" />

Answer 2

所以这就是我如何使用更新方法。

httpSession.getAttribute("loggedUser");//return type is Object here

使用Javascript：

 <form class="form-horizontal" role="form" method="POST" action="/manage_accounts/" novalidate>
          <input type="hidden" name="_method" value="PUT">

类名为.btn的模态按钮 - 编辑，

<script type="text/javascript">
$(function() {

  $('.btn--edit').on('click', function(e) {
    var userId = $(this).attr('data-for');
    var formAction = "/manage_accounts/" + userId;

    $('.form-horizontal').attr('action', formAction);
  });
</script>
