警告:mkdir():文件存在 [英] Warning: mkdir(): File exists

问题描述

传输到我的上载文件夹的文件运行良好，但是在 mkdir 中有一个警告.它说文件存在，但是图片和文件夹会生成自己的名称.我不知道警告正在确定.

The file transferring to my upload folder is working well but I have a warning in mkdir. It says file exist but the picture and folder generates own name. I don't know what warning is determining.

有人可以帮助我吗?

include('connect.php');

$dir=substr(uniqid(),-7); // Uniqid for subdirectory

$path = "uploads/$dir/"; // uploads/subdirectory/  // Make directory

$valid_formats = array("jpg", "png", "jpeg", "kml");

$max_file_size = 2097152;

$count = 0;


// Loop $_FILES to execute all files

 if(!empty($_FILES)){
foreach($_FILES['files']['name'] as $f => $name) {

    if ($_FILES['files']['error'][$f] == 4) {
        continue; // Skip file if any error found
    }  

    if ($_FILES['files']['error'][$f] == 0) {              
        if ($_FILES['files']['size'][$f] > $max_file_size) {
            $message[] = "$name is too large!.";
            continue; // Skip large files
        }

        elseif( ! in_array(pathinfo($name, PATHINFO_EXTENSION), $valid_formats) ){
            $message[] = "$name is not a valid format";
            continue; // Skip invalid file formats
        }

        else{ // No error found! Move uploaded files 
            mkdir($path, 0700);
            $ext = pathinfo($_FILES['files']['name'][$f], PATHINFO_EXTENSION);
            $uniq_name = substr(uniqid(),-5) . '.' .$ext;
            $dest = $path . $uniq_name;

            if(move_uploaded_file($_FILES["files"]["tmp_name"][$f], $dest)){

           $qry = "INSERT INTO files (code, name, path, type) VALUES ('$dir','$uniq_name','$dest','$ext')" ;

            $result = mysqli_query($dbc, $qry);
            if ( false===$result ) {
            $sql_error .= 'Error in the query '.$qry.'  Error Desc :'.mysqli_error($dbc).'<br /><br />' ;
                }
            }

        }

    }       
}}

推荐答案

警告很明显，您正在创建已经存在的目录.因此，只需将其更改为

Warning is quite clear, you are creating directory which already exists. So, just change it to

if (!file_exists($path)) {
    mkdir($path, 0700);
}
