Question

任何人都可以使用我的代码推断出这里可能出现的问题吗？当我尝试上传超过8 MB的PDF文件时，这就是我得到的消息：

出错了[没有上传文件]文件已在服务器上。

这是我输入的代码：

    <?php
    $name = $_FILES['file']['name']; 
    $storefile_loc = "uploads/"; 
    $storefile_path = $storefile_loc.basename($name);

    //$get_ext=explode(".",$_FILES['file']['name']); //separates file name from extension
    //$ext=end($get_ext); //gets the extension from above explosion
    $txtFileType = pathinfo($storefile_path,PATHINFO_EXTENSION);
    $goodext = array("txt","doc","odt","docx"); //array of extensions for app

    //Check if files are .txt (.doc, and .pdf functionality to be added)
    if (isset($_POST["submit"])){ //checks if form has been submitted
        //$check=mime_content_type($name);
        if (($_FILES['file']['type'] == "text/plain")
        ||($_FILES['file']['type'] == "application/pdf")
        ||($_FILES['file']['type'] == "application/vnd.oasis.opendocument.text")
        ||($_FILES['file']['type'] == "application/msword")
        ||($_FILES['file']['type'] == "application/vnd.openxmlformats-officedocument.wordprocessingml.document")
        &&(in_array($txtFileType,$goodext))){
            echo "Uploading File...";
        }
        else {
            echo "You can only upload a txt/doc/docx/pdf/odt file.";
        }
    }
    else {
        echo "Something went wrong [No file uploaded]";
    }

    //Check if file already exists. Probably won't need this
    if (file_exists($storefile_path)){ //this instead of $name because it's checking server
        echo "File already on server.";
    }

    //Check file size
    if  ($_FILES['file']['size'] > 2000000){
        echo "File is too large.";
    }   


    //Way to upload permanently. Probably won't need this
    /*
    if (move_uploaded_file($_FILES['file']['tmp_name'], $storefile_path)){
        echo "The file '".basename($_FILES['file']['name'])."' has been uploaded.";
    }
    else {
        echo "Something went wrong when uploading your file.";
    }
    */

    ?>

我也注意到第2行和第36行的错误。我的代码有问题吗？或者是Apache？

Answer 1

尝试在php.ini中增加这些设置，默认大小（通常）为8MB

  ; Maximum allowed size for uploaded files.
  upload_max_filesize = 40M;
  ; Must be greater than or equal to upload_max_filesize
  post_max_size = 40M;

之后，您必须重新启动服务器才能应用这些设置。

这意味着PHP将文件上传大小限制为这两个设置。你可能不需要40M，但你应该把它增加到你想要上传的最大文件的120％，这会给你一些喘息的空间。

这通常是我在服务器上配置的第一件事，我通常会做大约80MB，除此之外，我的客户更容易使用sFTP。

您需要添加通知错误行

$name = $_FILES['file']['name'];

和

if  ($_FILES['file']['size'] > 2000000){
    echo "File is too large.";
}

进入isset（＆＃39; POST＆＃39;）

if (isset($_POST["submit"])){
  $name = $_FILES['file']['name'];
  ...
  if  ($_FILES['file']['size'] > 2000000){
    echo "File is too large.";
  }
}

在php中获取文件上传错误
