jQuery，PHP上传文本文件，doc / docx，ppt / pptx，pdf [关闭]

Question

How can I upload txt, doc/docx, ppt/pptx, pdf and restrict all other file types while uploading file using php and jquery? Can i do it with jQuery also?

I have tried this.

$allowedExts = array("doc", "docx", "pdf", "txt");
$extension = end(explode(".", $_FILES["file"]["name"]));
if (($_FILES["file"]["type"] == "application/msword")
|| ($_FILES["file"]["type"] == "application/pdf")
|| ($_FILES["file"]["type"] == "application/txt") 
&& in_array($extension, $allowedExts)){}

I need it in JQuery or a better way in PHP.

Try this using php :

$fileTypes = array('txt','doc','docx','ppt','pptx','pdf'); // file extensions allowed
$fileParts = pathinfo($_FILES['file']['name']);

if(in_array($fileParts['extension'],$fileTypes))
{
   // upload file here if the extension matches to your allowed ones.
}
