php mkdir() 说没有这样的目录并且失败了？

mkdir() says theres no such directory and fails?

提问by rpsep2

Im likely doing something very simply wrong, but when I try to make a directory (using a variable of an insert just performed as the last folder name), I get the error:

我可能做了一些非常简单的错误，但是当我尝试创建目录时（使用刚刚执行的插入变量作为最后一个文件夹名称），我收到错误：

Warning: mkdir() [function.mkdir]: No such file or directory in /home/blah/blah

警告：mkdir() [function.mkdir]：/home/blah/blah 中没有这样的文件或目录

with the code:

使用代码：

if (!is_dir("images/listing-images/rent/'.$insertID.")) {
        //make new directory with unique id
   mkdir("images/listing-images/rent/'.$insertID."); 
}

of course the directory doesn't exist.. I'm trying to make it now? confused!

当然该目录不存在..我现在正在尝试制作它？使困惑！

You have an error in your string:

您的字符串中有错误：

mkdir("images/listing-images/rent/'.$insertID.");

should be:

应该：

mkdir("images/listing-images/rent/$insertID");

It happens because you don't have images/listing-images/rentpath existing in your filesystem.

发生这种情况是因为您images/listing-images/rent的文件系统中没有路径。

If you want to create the whole path - just pass the 3rd argument as a true:

如果要创建整个路径 - 只需将第三个参数作为 a 传递true：

mkdir('images/listing-images/rent/'.$insertID, 0777, true);

There is also a chance you're in a wrong directory currently. If this is the case - you need to change the current dir with chdir()or specify the full path.

您当前也有可能位于错误的目录中。如果是这种情况 - 您需要使用chdir()或指定完整路径来更改当前目录。

Assuming you're using PHP > 5.0.0, try mkdir("path", 0777, true);to enable creating directories recursively (see here: http://php.net/manual/en/function.mkdir.php).

假设您使用的是 PHP > 5.0.0，请尝试mkdir("path", 0777, true);启用递归创建目录（请参阅此处：http: //php.net/manual/en/function.mkdir.php）。

• recursive Allows the creation of nested directories specified in the path name.
• but did not work for me!! for that here is what i came up with!!
• and it work very perfect!!

• recursive 允许创建在路径名中指定的嵌套目录。
• 但对我不起作用！！因为这就是我想出的！！
• 它工作得非常完美！！

$upPath = "../uploads/RS/2014/BOI/002"; // full path
$tags = explode('/' ,$upPath); // explode the full path
$mkDir = "";

foreach($tags as $folder) {          
    $mkDir = $mkDir . $folder ."/";   // make one directory join one other for the nest directory to make
    echo '"'.$mkDir.'"<br/>';         // this will show the directory created each time
    if(!is_dir($mkDir)) {             // check if directory exist or not
      mkdir($mkDir, 0777);            // if not exist then make the directory
    }
}

$upPath = "../uploads/RS/2014/BOI/002"; // 完整路径
$tags = expand('/' ,$upPath); //
分解完整路径$mkDir = "";

foreach($tags as $folder) {          
    $mkDir = $mkDir . $folder ."/";   // make one directory join one other for the nest directory to make
    echo '"'.$mkDir.'"<br/>';         // this will show the directory created each time
    if(!is_dir($mkDir)) {             // check if directory exist or not
      mkdir($mkDir, 0777);            // if not exist then make the directory
    }
}

in my case $insertID was generated from some data as string by concatinating

在我的情况下 $insertID 是通过连接从某些数据作为字符串生成的

$insertID=$year.$otherId;

I simple rewrote code like this and error disappeared:

我简单地重写了这样的代码，错误消失了：

$insertID=(int)($year.$otherId);

回答by Luca Antonelli

Probably the real error was that he forgot an extra apex.

可能真正的错误是他忘记了一个额外的顶点。

This:

这个：

mkdir("images/listing-images/rent/'.$insertID.");

Inside:

里面：

/'.$insertID."

Correct Version:

正确版本：

/".$insertID

Extended Correct Version:

扩展正确版本：

mkdir("images/listing-images/rent/".$insertID);

You shouldn't use is_dir() to check if something exists, you want file_exists() as well. Try:

你不应该使用 is_dir() 来检查是否存在某些东西，你也需要 file_exists() 。尝试：

if (file_exists("images/listing-images/rent/$insertID") {
    mkdir("images/listing-images/rent/$insertID.");
}

Have taken the '. out since it looks like a syntax error, but you might have a legitimate reason to keep it in.

采取了'。出，因为它看起来像一个语法错误，但你可能有合法的理由保留它。

If the mkdir still fails, it could be that images/listing-images/rent doesn't exist, you'll have to create that separately if so.

如果 mkdir 仍然失败，则可能是 images/listing-images/rent 不存在，如果是这样，您必须单独创建。
