【WordPress】使用VSCode的SFTP來掛載WordPress的wp-content目錄

在這裏，我做了一個動作，為了方便測試開發WordPress的外掛與主題，我設置了sftp的遠端目錄至：

“remotePath”: “/home/u1085100/public_html/wp2/wp-content”,

在本地端，我則建立三個資料夾：

我的想法是，當我要寫或測試一個外掛時，我就在plugins下建一個外掛的資料夾，然後再用sftp:sync local->remote的方法，將新增的資料夾傳上主機。

建好後，我要測試file-upload-example這個外掛範例，那麼我就在本地端的plugins建立file-upload-example資料夾，並在該資料夾下建立file-upload-example.php，

程式碼：

<?php 
/* 
Plugin Name: File Upload Example
Description: demo plugin that demonstrates how to do file upload from admin page.
Author: Richard Dinh
//http://wordpress.stackexchange.com/questions/98375/how-to-upload-image-with-simple-form
this code is a demo only. You really should do more validation and stuff
*/

// add the admin options page
add_action('admin_menu', 'file_upload_example_admin_add_page');

function file_upload_example_admin_add_page() {
    add_options_page('File Upload Example', 'File Upload Example', 'manage_options', 'file-upload-example', 'file_upload_example_options_page');    

}

function file_upload_example_options_page() {
    if ( empty( $_FILES ) ){
?>
    <div>
        <h2>Upload a file here</h2>
        <form action="" method="post" enctype="multipart/form-data">
        <?php wp_nonce_field('csv-import'); ?>

        <label for="file">Filename:</label>
        <input type="file" name="file" id="file"><br>
        <input type="submit" name="save" value="save">
        </form>
    </div>
    <?php } 
    else{ 
      if ( ! function_exists( 'wp_handle_upload' ) ) 
          require_once( ABSPATH . 'wp-admin/includes/file.php' );
          $uploadedfile = $_FILES['file'];
          $upload_overrides = array( 'test_form' => false );
          $movefile = wp_handle_upload( $uploadedfile, $upload_overrides );
          if ( $movefile ) {
              echo "File is valid, and was successfully uploaded.n";
              var_dump( $movefile );
              // here you can do some stuff with this
          } else {
              echo "Possible file upload attack!n";
          }
    }
}

存檔(或按下ctrls+S)就可以在遠端自動建立file-upload-example資料夾，並且將file-upload-example.php上傳至主機。(請自行透過ftp或後台檔案管理員檢查，資料夾與檔案是否已經在主機上了。) 然後到WordPress後台的已安裝外掛中，啟用file-upload-examp這個外掛：
