当用户提交表单时,他们输入参考编号并最多可以上传3个文档。
当他们提交时,我希望将文档保存在文件夹结构中,如下所示:
docs/
12345/1/file.jpg
12345/2/file.jpg
anotherfile.jpg
27635/1/afile.png
anotherfile.png
thirdfile.jpg
34827/1/onefile.jpg
好的,所以你明白了,当用户上传文件时,它会在docs /中创建一个新的文件夹,并带有参考号,然后创建另一个名为1 /的文件夹。如果用户随后使用相同的引用再次上传,则会在其引用中创建一个文件夹,其中包含其文件的下一个数字。
HTML:
<form action="upload.php" method="post" enctype="multipart/form-data">
<input type="text" name="reference"/><br/>
<input type="file" name="pictures[]" /><br/>
<input type="file" name="pictures[]" /><br/>
<input type="file" name="pictures[]" /><br/>
<input type="submit" value="Send" />
</form>
PHP:
<?php
$target_dir = "docs/";
$ref = $_POST['reference'];
if(!file_exists($target_dir . $ref . '/')){
mkdir($target_dir . $ref . "/1/");
$count = 0;
}else{
//count the amount of folders inside docs/$ref/
$find_folders = glob($target_dir . $ref . "/*",GLOB_ONLYDIR);
$count = count($find_folders);
//create new folder inside $ref/ using count+1 to make the folder increase by 1
$new_folder = $count +1;
mkdir($target_dir . $ref . "/" . $new_folder . "/");
}
//If count exists then the $target_file changes to the new folder
if($count > 0){
$target_file = $target_dir . $ref . $new_folder . "/";
}else{//else use first directory
$target_file = $target_dir . $ref ."/1/";
}
foreach ($_FILES["pictures"]["name"] as $key => $Name)
{
$tmp_name = $_FILES["pictures"]["tmp_name"][$key];
$name = $_FILES["pictures"]["name"][$key];
move_uploaded_file($tmp_name, $target_file . "$name");
}
?>
当我尝试所有我得到的是错误: 警告:mkdir():第8行的C:\ wamp \ www \ test \ upload.php中没有这样的文件或目录
arning:move_uploaded_file(docs / 123/1 / 1.png):无法打开流:第32行的C:\ wamp \ www \ test \ upload.php中没有此类文件或目录
警告:move_uploaded_file():无法移动&#39; C:\ wamp \ tmp \ php2E4E.tmp&#39;到&#39; docs / 123/1 / 1.png&#39;在第32行的C:\ wamp \ www \ test \ upload.php
有关于此的任何想法吗?我只是抓住这一个
答案 0 :(得分:1)
我看到了2个问题。
首先,当您使用Windows时,您需要使用\而不是/作为目录分隔符。最好使用php常量DIRECTORY_SEPARATOR
。
其次,为了递归创建目录,你需要mkdir的第三个参数,如此
mkdir($mypath,0777,TRUE);
把它放在一起你应该得到这样的东西:
$target_dir = "docs".DIRECTORY_SEPARATOR;
$ref = $_POST['reference'];
if(!file_exists($target_dir . $ref . DIRECTORY_SEPARATOR)){
mkdir($target_dir . $ref . DIRECTORY_SEPARATOR . "1" . DIRECTORY_SEPARATOR, 0777, true);
$count = 0;
}else{
//count the amount of folders inside docs/$ref/
$find_folders = glob($target_dir . $ref . DIRECTORY_SEPARATOR . "*",GLOB_ONLYDIR);
$count = count($find_folders);
//create new folder inside $ref/ using count+1 to make the folder increase by 1
$new_folder = $count +1;
mkdir($target_dir . $ref . DIRECTORY_SEPARATOR . $new_folder . DIRECTORY_SEPARATOR, 0777, true);
}
//If count exists then the $target_file changes to the new folder
if($count > 0){
$target_file = $target_dir . $ref . DIRECTORY_SEPARATOR . $new_folder . DIRECTORY_SEPARATOR;
}else{//else use first directory
$target_file = $target_dir . $ref . DIRECTORY_SEPARATOR . "1" . DIRECTORY_SEPARATOR;
}
