Customize the table where clicks to add data in Dcat Admin
This article describes how to create a custom table in Dcat Admin (Laravel-Admin), allowing users to click on buttons to add data, and supports editing quantity and colors in the table. The following figure shows the target function:
Implementation steps
1. Create a table and add buttons:
In Dcat Admin, create a table using grid
and add a button to the table toolbar to trigger the Add Data Action. The following code snippet shows how to create a table and add a button:
use Dcat\Admin\Grid; use Dcat\Admin\Layout\Content; public function index(Content $content) { return $content ->header('Data Management') ->description('Add data') ->body($this->grid()); } protected function grid() { $grid = new Grid(new YourModel()); $grid->tools(function (Grid\Tools $tools) { $tools->append(new \Dcat\Admin\Grid\Tools\Button('Ad data', 'btn-add-data')->class('btn btn-primary')); }); // Table column definition $grid->column('id', 'ID'); $grid->column('name', 'name'); $grid->column('quantity', 'quantity')->editable(); $grid->column('color', 'color')->select(['red' => 'red', 'blue' => 'blue', 'green' => 'green']); return $grid; }
2. Front-end JavaScript code:
Use the jQuery binding button to click the event, obtain the data through the AJAX request server and add the data to the table. Note that replace /admin/your-endpoint
for your backend processing interface address, #your-grid-id
for your table ID. For a better user experience, it is recommended to use the table operation method provided by Dcat Admin instead of directly operating the DOM.
$(document).on('click', '.btn-add-data', function () { let id = prompt("Please enter ID"); if (id) { $.ajax({ url: '/admin/your-endpoint', type: 'GET', data: { id: id }, success: function (data) { if (data) { // Add rows using Dcat Admin method instead of directly manipulating the DOM Dcat.grid.appendRow('#your-grid-id', data); // Replace #your-grid-id as your table ID } else { alert('No data found'); } }, error: function (error) { alert('Request failed: ' error.responseText); } }); } });
3. Backend handles AJAX requests:
The backend controller method processes AJAX request, querys data based on ID and returns JSON data.
use Illuminate\Http\Request; public function getDatum(Request $request) { $id = $request->input('id'); $data = YourModel::find($id); if ($data) { return response()->json($data); } else { return response()->json(null); } }
4. Improvement suggestions (using Dcat Admin's table API):
To better integrate the functionality of Dcat Admin, it is recommended to use the API provided by Dcat Admin to manipulate tables instead of directly manipulating the DOM. This ensures that your code is compatible with updates from Dcat Admin and gets better maintenance. For example, you might consider adding rows using Dcat.grid.addRow()
or similar. This requires reference to the documentation of Dcat Admin to determine the most appropriate API method.
Through the above steps, you can create a custom click-add data table in Dcat Admin. Remember to replace YourModel
with your model name and adjust the code according to your actual situation. Using the API provided by Dcat Admin can make your code more concise, easier to maintain, and better integrate with the framework.

In PHP, you can use session_status() or session_id() to check whether the session has started. 1) Use the session_status() function. If PHP_SESSION_ACTIVE is returned, the session has been started. 2) Use the session_id() function, if a non-empty string is returned, the session has been started. Both methods can effectively check the session state, and choosing which method to use depends on the PHP version and personal preferences.

Managing concurrent session access in PHP can be done by the following methods: 1. Use the database to store session data, 2. Use Redis or Memcached, 3. Implement a session locking strategy. These methods help ensure data consistency and improve concurrency performance.

Load balancing affects session management, but can be resolved with session replication, session stickiness, and centralized session storage. 1. Session Replication Copy session data between servers. 2. Session stickiness directs user requests to the same server. 3. Centralized session storage uses independent servers such as Redis to store session data to ensure data sharing.

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching

Sessionhijacking refers to an attacker impersonating a user by obtaining the user's sessionID. Prevention methods include: 1) encrypting communication using HTTPS; 2) verifying the source of the sessionID; 3) using a secure sessionID generation algorithm; 4) regularly updating the sessionID.
