- Sau đây tôi sẽ tiến hành chèn dữ liệu vào post có type ws_device có đường dẫn data/device
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
ws_register_generic_import_handler('ws_action_import_data', [ 'path_dir' => plugin_dir_path(__FILE__) . '../data/device', 'post_type' => 'ws_device', 'transient_key' => 'ws_data_import_current', 'meta_fields' => [ 'device_price' => 'price', 'device_excerpt' => 'description', ], 'default_meta_fields' => [ 'device_type' => [ 'prefix' => 'device_type', 'value' => 'teambuilding', ], ], 'excerpt_key' => 'device_excerpt', ]); |
- Tiếp theo sẽ tạo 1 trang trong admin để quản lí việc chèn dữ liệu

add_action('admin_menu', 'ws_import_menu'); function ws_import_menu() { add_menu_page( 'Import WS Devices', 'Import Data', 'manage_options', 'ws_action_import_data', 'ws_import_page', 'dashicons-upload', 20 ); } function ws_import_page() { ?> <div class="wrap"> <h1>Import WS Data</h1> <button id="start-import" class="button button-primary">Start Import</button> <div id="import-progress" style="margin-top: 20px;"> <p>Progress: <span id="progress-text">0%</span></p> <progress id="progress-bar" value="0" max="100"></progress> <div id="import-log"></div> </div> </div> <script> jQuery(document).ready(function ($) { $('#start-import').on('click', function () { $(this).prop('disabled', true); startImport(); }); function startImport() { $.ajax({ url: ajaxurl, type: 'POST', data: { action: 'ws_action_import_data', start: 1 }, success: function (response) { if (response.success) { updateProgress(response.data); if (response.data.complete) { $('#progress-text').text('100%'); $('#progress-bar').val(100); $('#import-log').append('<p>Import completed!</p>'); } else { startImport(); } } else { $('#import-log').append('<p>Error: ' + response.data.message + '</p>'); } }, error: function () { $('#import-log').append('<p>AJAX error occurred.</p>'); } }); } function updateProgress(data) { $('#progress-text').text(data.progress + '%'); $('#progress-bar').val(data.progress); $('#import-log').append('<p>' + data.message + '</p>'); } }); </script> <?php } |
- Sau đó refesh lại page thì ta thấy trong admin sẽ có trang import
- Cấu trúc folder data import có dạng data/device/folder-name-device
- Trong folder-name-device/info.txt chứa thông tin device có dạng và folder-name-device/name-image.[jpg,png,gif,webp]
- Bên dưới là cấu trúc file info.txt
