Question

这是一个WordPress插件，可以上传图片。目前，图像已上传到：http://localhost/wp-content/2018/10/image.png。我希望将它们存储在网站的根目录中。在主文件夹中，有wp-content，wp-admin和其他文件之类的文件夹。

这是将文件上传到上面指定的目标的代码。

 <div class="wrap">
<h2>Upload files</h2>
<form action="" method="post" enctype="multipart/form-data">
Select file to upload (Supported files: .rar, .zip, .txt, .xml):
<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="Upload Image" name="submit">
</form>
</div>
<?php
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
    $target_dir = wp_upload_dir();
    $target_file = $target_dir['path'] . '/' . 
basename($_FILES["fileToUpload"]["name"]);
    $uploadOk = 1;
    $imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
    $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check !== false) {
        echo "File is an image - " . $check["mime"] . ".";
        $uploadOk = 1;
    } else {
        echo "File is not an image.";
        $uploadOk = 0;
    }
    // Check if file already exists
    if (file_exists($target_file)) {
        echo "Sorry, file already exists.";
        $uploadOk = 0;
    }
    // Check file size
    if ($_FILES["fileToUpload"]["size"] > 500000) {
        echo "Sorry, your file is too large.";
        $uploadOk = 0;
    }
    // Allow certain file formats
    if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType 
!= 
        "jpeg"
    && $imageFileType != "gif" ) {
        echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
        $uploadOk = 0;
    }
    // Check if $uploadOk is set to 0 by an error
    if ($uploadOk == 0) {
        echo "Sorry, your file was not uploaded.";
        // if everything is ok, try to upload file
    } else {
        if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], 
$target_file)) {
            echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " 
has been 
                uploaded.";
        } else {
            echo "Sorry, there was an error uploading your file.";
        }
    }

}



}

应该是这样的： / home / user / public_html /或 /用户/用户名/站点/ wp / 或类似的东西，但我不知道如何实现。

您需要添加此功能才能获取根路径get_home_path()。

更改此行

$target_file = $target_dir['path'] . '/' . basename($_FILES["fileToUpload"]["name"]);

在下面

$target_file = get_home_path() . '/' . basename($_FILES["fileToUpload"]["name"]);

如何将上传文件的$ target_dir更改为绝对路径-网站根目录？
