PHP多文件上传

我有一个用于文件上传的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？我试着简单地将multiple=“multiple”添加到我的文件上传表单（允许我选择多个文件），但在目录中只上传了一个文件。表格如下：

<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>

选择要上载的图像：

操作页面的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;
      }
    }
?>

您可以更改此选项

<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>

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>
