将文件上载到目录

标签: php html file upload

我现在有一个php文件,可以将文件上传到我的网络服务器。目前它将上传诸如jpg文件之类的文件,但每当我尝试上传excel或word文件时(说实话,我需要的)它不会呈现我的代码而只是说'无效文件'。我没有错误,因为它只回到最后一行。任何想法都将不胜感激。

<?php
include 'dbconnect.php';
$target_path = "uploads/"; 
$target_path = $target_path . basename( $_FILES['file']['name']);  

//$allowedExts = array("gif", "jpeg", "jpg", "png");
//$temp = $target_path . basename($_FILES['file']['name']);
//$extension = end($temp);


if (($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/jpg")
|| ($_FILES["file"]["type"] == "image/pjpeg")
|| ($_FILES["file"]["type"] == "image/x-png")
|| ($_FILES["file"]["type"] == "image/png")
|| ($_FILES["file"]["type"] == "text/plain")
|| ($_FILES["file"]["type"] == "application/msword")
|| ($_FILES["file"]["type"] == "application/vnd.ms-excel")
&& ($_FILES["file"]["size"] < 2000000))
  {
  if ($_FILES["file"]["error"] > 0)
    {
    echo "Return Code: " . $_FILES["file"]["error"] . "<br>";
    }
  else
    {
    echo "Upload: " . $_FILES["file"]["name"] . "<br>";
    echo "Type: " . $_FILES["file"]["type"] . "<br>";
    echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";
    echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br>";

    if (file_exists("upload/" . $_FILES["uploadedfile"]["tmp_name"]))
      {
      echo $_FILES["file"]["name"] . " already exists. ";
      }
    else
      {
      move_uploaded_file($_FILES['file']['tmp_name'], $target_path);
        echo "The file ".  basename( $_FILES['file']['name']).  
        " has been uploaded"; 
    }
    }
  }
else
  {
  echo "Invalid file";
  }
?>

您的代码没问题。您收到“文件无效”消息,因为您的文件大小&gt; = 20000或您的文件类型与您的过滤器不匹配。只需增加php代码中的文件大小,并确保只上传“gif”,“jpeg”,“jpg”或“png”文件。

您的ms-word .doc文件将与您的代码完美地加载。但是,如果您尝试上传.docx文件(即ms-word 2007以后的默认文件),那么您的代码将无效。 为了使它工作使用..  “应用程序/ vnd.openxmlformats-officedocument.wordprocessingml.document”     此外  “应用程序/ msword”

同样在您的代码更改中

if(file_exists(“upload /”。$ _FILES [“uploadedfile”] [“tmp_name”]))

                to

if(file_exists(“upload /”。$ _FILES [“file”] [“name”]))
