PHP代码

  <?php
    if (($_FILES['my_file']['name']!="")){
    // Where the file is going to be stored
        $target_dir = "upload/";
        $file = $_FILES['my_file']['name'];
        $path = pathinfo($file);
        $filename = $path['filename'];
        $ext = $path['extension'];
        $temp_name = $_FILES['my_file']['tmp_name'];
        $path_filename_ext = $target_dir.$filename.".".$ext;

    // Check if file already exists
    if (file_exists($path_filename_ext)) {
     echo "Sorry, file already exists.";
     }else{
     move_uploaded_file($temp_name,$path_filename_ext);
     echo "Congratulations! File Uploaded Successfully.";
     }
    }
    ?>

就像我说的，它报告文件已成功上传，但实际上并未存储和上传任何内容。

Answer 1

是的，该文件可能已上传，但您无法检查是否已存储该文件。成功时move_uploaded_file返回true，失败时返回false http://php.net/manual/en/function.move-uploaded-file.php，因此您需要检查它是否返回任何错误。

问题可能与您尝试在

中存储文件的文件夹的写访问有关

Answer 2

我发现使用绝对路径而不是相对路径效果更好 - 它可能在* nix系统上有所不同，但肯定在Windows上是真的。

<?php
    $fieldname='my_file';
    if( isset( $_FILES[ $fieldname ] ) ){

        $target_dir = $_SERVER['DOCUMENT_ROOT'] . '/upload/';
        $file = $_FILES[ $fieldname ]['name'];
        $tmp = $_FILES[ $fieldname ]['tmp_name'];

        $filename = pathinfo( $file, PATHINFO_FILENAME );
        $targetpath = $target_dir . $filename;

        if( !file_exists( $target_dir ) ){
            exit('Error: Target directory does not exist');
        }
        clearstatcache();

        if( file_exists( $targetpath ) ) {
            echo 'Sorry, file already exists.';
        }else{
            $results = move_uploaded_file( $tmp, $targetpath );
            echo $results ? 'Congratulations! File Uploaded Successfully.' : 'Error-Failed to store file';
        }
        clearstatcache();
    }
?>

PHP上传工作，但不将文件存储在目录中作为编码
