照片上传不能上传大于2MB的文件 [英] Photo upload not uploading files bigger than 2MB

问题描述

我有一个php文件上传，其中表单目标是一个iframe。

它上传小于2mb的文件。但是更大的东西不会上传。

 < div id =upload_wrapper>我不能在代码中看到任何原因。 
 
 < h3>个人资料图片上传< / h3> 
 
< form id =uploadname =uploadenctype =multipart / form-datamethod =postaction =index.phptarget =upload_target> 
< input name =foldertype =hiddenvalue =<？php echo $ folder？> /> 
< input name =filenametype =hiddenvalue =<？php echo $ filename？> /> 
< input name =uploaded_filetype =filesize =5120id =uploaded_file/> 
< input id =sentname =senttype =submitvalue =Upload/> 
< / form> 
< / div> 
< div id =loadingstyle =background：url（ajax-loader.gif）no-repeat left; height：50px; width：370px; display：none;> 
< p style =margin-left：40px; padding-top：15px;>正在上传档案...请稍候< / p> 
< / div> 
< div id =image_wrapperstyle =display：none;>< p id =preview>< / p>< / div> 
< iframe id =upload_targetname =upload_targetstyle =width：10px; height：10px; display：none>< / iframe> 
< / div> 
  

继承人php上传代码

<$ p $（$ _SERVER ['REQUEST_METHOD'] =='POST'）{

$ targetFolder = $ _POST ['folder']。 /;
$ filename2 = $ _POST ['filename'];

if（！is_dir（$ targetFolder））
{
mkdir（$ targetFolder，0777）;
}

$ tempFile = $ _FILES ['uploaded_file'] ['tmp_name'];
$ targetPath = dirname（__ FILE__）。 '/'。 $ targetFolder;
$ targetFile = rtrim（$ targetPath，'/'）。 '/'。 $ _FILES [ uploaded_file] [名];

//验证文件类型
$ fileTypes = array（'jpg'）; //文件扩展名
$ fileParts = pathinfo（$ _ FILES ['uploaded_file'] ['name']）;

if（in_array（$ fileParts ['extension']，$ fileTypes））
{
$ uploadfile = $ targetFolder。 basename（$ filename2。。。$ fileParts ['extension']）;
move_uploaded_file（$ tempFile，$ uploadfile）;
$ fileName = $ uploadfile;
}

echo< div id ='filename'> $ fileName< / div>;

解决方案

你的PHP服务器的配置将有所帮助（例如10MB）：

  ini_set（'upload_max_filesize'，'10M'）; 
  

I have a php file upload in place in which the forms target is an iframe.

It uploads files less than 2mb fine. But anything larger it will not upload. I cant see any reason behind this in the code.

<div id="upload_wrapper">

<img src="../images/logo.png" alt="logo5" width="" height="" style="padding:0px;" />
<h3>Profile picture upload</h3>

  <form id="upload" name="upload" enctype="multipart/form-data" method="post" action="index.php" target="upload_target">
    <input name="folder" type="hidden" value="<?php echo $folder ?>"  />
    <input name="filename" type="hidden" value="<?php echo $filename ?>"  />
    <input name="uploaded_file" type="file" size="5120" id="uploaded_file"  />
    <input id="sent" name="sent" type="submit"  value="Upload" />
  </form>
</div>
<div id="loading" style="background:url(ajax-loader.gif) no-repeat left; height:50px; width:370px; display:none;">
  <p style="margin-left:40px; padding-top:15px;">Uploading File... Please wait</p>
</div>
<div id="image_wrapper" style="display:none;"><p id="preview"></p></div>
<iframe id="upload_target" name="upload_target" style="width:10px; height:10px; display:none"></iframe>
</div>

And heres the php upload code

if ($_SERVER['REQUEST_METHOD'] == 'POST') {

$targetFolder = $_POST['folder'] . "/";
$filename2 = $_POST['filename'];

if (!is_dir($targetFolder)) 
{
    mkdir($targetFolder, 0777);
}

    $tempFile = $_FILES['uploaded_file']['tmp_name'];
    $targetPath = dirname(__FILE__) . '/' . $targetFolder;
    $targetFile = rtrim($targetPath,'/') . '/' . $_FILES['uploaded_file']['name'];

    // Validate the file type
    $fileTypes = array('jpg'); // File extensions
    $fileParts = pathinfo($_FILES['uploaded_file']['name']);

    if (in_array($fileParts['extension'],$fileTypes)) 
    {
        $uploadfile = $targetFolder. basename($filename2 .".".$fileParts['extension']);
         move_uploaded_file($tempFile,$uploadfile);
         $fileName = $uploadfile;
    }

    echo "<div id='filename'>$fileName</div>";

}

解决方案

Maybe changing your php server's configuration would help (example for 10MB):

ini_set('upload_max_filesize', '10M');
