Wordpress: PHP多文件上传

Question

我有一个文件上传的HTML表单，它将上传的文件发送到我的wordpress站点的后端目录。如何启用多个文件上载？我尝试将multiple=" multiple“添加到我的文件上传表单(它允许我选择多个文件)，但是在目录中只有一个文件被上传。这是表格：

<form action="http://www.aerex.co.uk/php-upload/" method="post" enctype="multipart/form-data">
    Select image to upload:
    <input type="file" name="fileToUpload" id="fileToUpload" multiple="multiple">
    <input type="submit" value="Upload Image" name="submit">
</form>

动作页面的PHP：

<?php
    $target_dir = $_SERVER['DOCUMENT_ROOT'] . '/wp-content/uploads/';
    $target_file = $target_dir . '/' . basename($_FILES["fileToUpload"]["name"]);
    move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file);
    $uploadOk = 1;
    $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
    // Check if image file is a actual image or fake image
    if(isset($_POST["submit"])) {
         $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
          if($check !== false) {
            echo "File is an image - " . $check["mime"] . ".";
            $uploadOk = 1;
            } else {
             echo "File is not an image.";
             $uploadOk = 0;
      }
    }
?>

你改变这个

<form action="http://www.aerex.co.uk/php-upload/" method="post" enctype="multipart/form-data">
    Select image to upload:
    <input type="file" name="fileToUpload[]" id="fileToUpload" multiple="multiple">
    <input type="submit" value="Upload Image" name="submit">
</form>

和你的php

$target_dir = $_SERVER['DOCUMENT_ROOT'] . '/wp-content/uploads/';
if(isset($_POST) and $_SERVER['REQUEST_METHOD'] == "POST"){
  foreach ($_FILES['fileToUpload']['name'] as $f => $name) {     
    if(isset($_POST["submit"])) { 
     $target_file = $target_dir . '/' . basename($_FILES["fileToUpload"]["name"][$f]);
      move_uploaded_file($_FILES["fileToUpload"]["tmp_name"][$f], $target_file);
      $uploadOk = 1;
      $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
           $check = getimagesize($target_file);
            if($check !== false) {
              echo "File is an image - " . $check["mime"] . ".";
              $uploadOk = 1;
              } else {
               echo "File is not an image.";
               $uploadOk = 0;
        }
    }

  }
}
