Question

我有这个代码用于上传服务器上的文件。但我得到一个由else语句生成的自定义错误，但我需要知道php无法上传文件的真正原因。我收到错误2但我没有得到实际的消息。有什么建议吗？

if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path."/")) {
            echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded";
        } else{
            echo "There was an error uploading the file, please try again! ".$_FILES['uploadedfile']['error'];
        }

Answer 1

我不确定为什么要在目标参数$target_path."/"的末尾添加目录分隔符。

删除它或替换为$target_path.basename( $_FILES['uploadedfile']['name'])应该可以解决问题。

<?php 
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
    echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded";
} else{
    echo "There was an error uploading the file, please try again! ".$_FILES['uploadedfile']['error'];
}
?>

你可以尝试这个实际发生的错误

  $upload_errors = array(
    UPLOAD_ERR_OK        => "No errors.", 
    UPLOAD_ERR_INI_SIZE    => "Larger than upload_max_filesize.",
    UPLOAD_ERR_FORM_SIZE    => "Larger than form MAX_FILE_SIZE.",
    UPLOAD_ERR_PARTIAL    => "Partial upload.",
    UPLOAD_ERR_NO_FILE        => "No file.",
    UPLOAD_ERR_NO_TMP_DIR    => "No temporary directory.",
    UPLOAD_ERR_CANT_WRITE    => "Can't write to disk.",
    UPLOAD_ERR_EXTENSION     => "File upload stopped by extension.",
    UPLOAD_ERR_EMPTY        => "File is empty." // add this to avoid an offset
  );
   // error: report what PHP says went wrong
   $err =  $upload_errors[$_FILES['uploadedfile']['error']];

   echo $err;

使用php上传文件时出现Apear错误
