Question

我有文件上传脚本，我有一个if语句，检查文件是否不存在，它会创建一个并将文件上传到它，如果它存在，它会将文件上传到它。

<?php
ini_set('post_max_size', '40M');
ini_set('upload_max_filesize', '40M');

if (isset($_POST['do']) and $_POST['do'] == 'upload') {
    $filename = $_FILES['file']['name'];
    $filesize = $_FILES['file']['size'];
    $tmp_name = $_FILES['file']['tmp_name'];
    $file_type = $_FILES['file']['type'];
    $date = "[".date("d-m-Y_H-i")."]";
    $temp = explode(".", $filename);
    $new_filename = $temp[0] . ""/*you can put any thing that you want before the [] in the 2 singels*/ . $date .'.' . end($temp);
    $f_folder = "uploads" . DIRECTORY_SEPARATOR .$_POST['user'] . DIRECTORY_SEPARATOR . $new_filename;
    $username = $_POST['user'];

    //echo $username;
    if (!file_exists("uploads". DIRECTORY_SEPARATOR .$_POST['user'])){
    mkdir("uploads" . DIRECTORY_SEPARATOR . $_POST['user'],0777);
        if (empty($filename)) {
            echo "choose file please";
    }else {
           move_uploaded_file($tmp_name, $f_folder);
           echo "file is uploaded in " . $f_folder;
    }
    }else if (empty($filename)) {
            echo "choose file please";
        }else {
            move_uploaded_file($tmp_name, $f_folder);
            echo "file is uploaded in " . $f_folder;
    };


};

echo "<hr>";
 echo "
<form method='post' enctype='multipart/form-data' >
    File Path : <input type='file' name='file' />
    <br>
    Username : <input type='text' name='user' />
    <br>
    <input type='submit' name='do' value='upload' />
</form>";

?>

它工作正常但是当我上传照片时，我无法打开它。它给了我以下错误：

Windows照片查看器无法打开此图片，因为您没有正确的访问文件位置的权限

使用php的chmod()功能在图片上传后设置权限。

<?php
if (!file_exists("uploads". DIRECTORY_SEPARATOR .$_POST['user'])){
$oldmask = umask(0);
mkdir("uploads" . DIRECTORY_SEPARATOR . $_POST['user'],777);
umask($oldmask);
    if (empty($filename)) {
        echo "choose file please";
}else {
       move_uploaded_file($tmp_name, $f_folder);
       echo "file is uploaded in " . $f_folder;
}
}else if (empty($filename)) {
        echo "choose file please";
    }else {
        move_uploaded_file($tmp_name, $f_folder);
        echo "file is uploaded in " . $f_folder;
}
chmod($f_folder, 777); // add this line after image upload

因为您没有权限
