PHP上传一个文件到选定的子目录

Question

我有一个表单将上传到它所在的目录，但我需要它从一个选择上传到子目录或子目录的子目录。但不确定如何使用选择信息。

我的文件夹结构为4层文件夹

Produce 
Produce/Meat 
Produce/Meat/Beef 
Produce/Meat/Beef/Portions 
Produce/Meat/Beef/Packaged 
Produce/Vegtables 
Produce/Vegetables/Fresh 
Produce/Vegetables/Fresh/Local etc,. 

这是我的形式

<form id="Upload" action="upload_file.php" method="post" enctype="multipart/form-data"> 
<br> 
     <label for="fileSelect"><strong>There is a 10MB limit Filesize limit.</strong> Allowed file types are pictures, MSWord, MSExcel, PDF, and plain text. Navigate and choose:</label> 
     <input type="file" name="file" id="fileSelect"><br><br> 
     Upload to: 
     <select name="folder"><option value="this" selected>This folder</option><option value="BBB">Meat</option><option value="CCC">Meat/Beef</option><option value="DDD">Meat/Beef/Portions</option><option value="EEE">Meat/Beef/Packaged</option><option value="FFF">Vegetables</option><option value="GGG">Vegetables/Fresh</option><option value="HHH">Vegetables/Fresh/Local</option><option value="III">Vegetables/Fresh/Packaged</option></select> 
     <input class="button" type="submit" name="action" value="Upload to Shared Folder"><br><br> 
    </form> 

然后upload_file.php有这个PHP代码

<?php 

if(isset($_FILES["file"]["error"])){ 
    if($_FILES["file"]["error"] > 0){ 
     echo "Error: " . $_FILES["file"]["error"] . "<br>"; 
    } else{ 
     $allowed = array("jpg" => "image/jpg", "jpeg" => "image/jpeg", "gif" => "image/gif", "png" => "image/png", "doc" => "application/msword", "docx" => "application/vnd.openxmlformats-officedocument.wordprocessingml.document", "xls" => "application/vnd.ms-excel", "xlsx" => "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", "pdf" => "application/pdf", "txt" => "text/plain"); 
     $filename = $_FILES["file"]["name"]; 
     $filetype = $_FILES["file"]["type"]; 
     $filesize = $_FILES["file"]["size"]; 

     // Verify file extension 
     $ext = pathinfo($filename, PATHINFO_EXTENSION); 
     if(!array_key_exists($ext, $allowed)) die("Error: This file is not an accepted file type.</br></br>"); 

     // Verify file size - 10MB maximum 
     $maxsize = 200000 * 60; 
     if($filesize > $maxsize) die("Error: File size is larger than the allowed 10MB limit.</br></br>"); 

     // Verify MYME type of the file 
     if(in_array($filetype, $allowed)){ 
      // Check whether file exists before uploading it 
      if(file_exists("general/" . $_FILES["file"]["name"])){ 
       echo $_FILES["file"]["name"] . " already exists. Go back and choose another file or rename the original.</br></br>"; 
      } else{ 
       move_uploaded_file($_FILES["file"]["tmp_name"], "" . $_FILES["file"]["name"]); 
       echo "The file was uploaded successfully.</br></br>"; 
      } 
     } 
     else{ 
      echo "Error: There was a problem uploading the file - please try again."; 
     } 
    } 
} else{ 
    echo "Error: Invalid parameters - something is very wrong with this upload."; 
} 
?> 

有没有一种方法我可以将选择的值并上传到选择的子目录中？

Answer 1

有很多方法可以做到这一点，所以这里有一个方法：

检查，看是否POST阵列设置（在下拉列表中选择），然后内部检查，看它是否等于值从选项中，然后将文件移动到所选文件夹内：

if(isset($_POST['folder'])){ 

    if($_POST['folder'] == 'this'){ 

    // move_uploaded_file to said folder 

    } 

    if($_POST['folder'] == 'BBB'){ 

    // move_uploaded_file to said folder 

    } 

    // ... do the same for the others below 


} 

您还可以设置默认的上传文件夹。

注意：找我的原代码段内// My snippet START --- // My snippet END。

<?php 

if(isset($_FILES["file"]["error"])){ 
    if($_FILES["file"]["error"] > 0){ 
     echo "Error: " . $_FILES["file"]["error"] . "<br>"; 
    } else{ 
     $allowed = array("jpg" => "image/jpg", "jpeg" => "image/jpeg", "gif" => "image/gif", "png" => "image/png", "doc" => "application/msword", "docx" => "application/vnd.openxmlformats-officedocument.wordprocessingml.document", "xls" => "application/vnd.ms-excel", "xlsx" => "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", "pdf" => "application/pdf", "txt" => "text/plain"); 
     $filename = $_FILES["file"]["name"]; 
     $filetype = $_FILES["file"]["type"]; 
     $filesize = $_FILES["file"]["size"]; 

     // Verify file extension 
     $ext = pathinfo($filename, PATHINFO_EXTENSION); 
     if(!array_key_exists($ext, $allowed)) die("Error: This file is not an accepted file type.</br></br>"); 

     // Verify file size - 10MB maximum 
     $maxsize = 200000 * 60; 
     if($filesize > $maxsize) die("Error: File size is larger than the allowed 10MB limit.</br></br>"); 

     // Verify MYME type of the file 
     if(in_array($filetype, $allowed)){ 
      // Check whether file exists before uploading it 
      if(file_exists("general/" . $_FILES["file"]["name"])){
