PHP文件上传与PDF / DOCX而不是图像 [英] PHP fileUpload with Pdf/Docx Instead of Image

问题描述

 <？php 
 $ target_dir =上传/; 
 $ target_file = $ target_dir。基名（$ _ FILES [ fileToUpload] [ 名称]）; 
 $ uploadOk = 1; 
 $ imageFileType = pathinfo（$ target_file，PATHINFO_EXTENSION）; 
 
 if（isset（$ _ POST [submit]））{
 $ check = getimagesize（$ _ FILES [fileToUpload] [tmp_name]）; 
 if（$ check！== false）{
 echoFile is a image  - 。 $ check [mime]。 ; 
 $ uploadOk = 1; 
} else {
 echo文件不是图像。 
 $ uploadOk = 0; 
 
 
 $ b $ if（file_exists（$ target_file））{
 echoSorry，file already exists。; 
 $ uploadOk = 0; 
 
 
 if（$ _FILES [fileToUpload] [size]> 500000）{
 echo抱歉，您的文件太大了。 
 $ uploadOk = 0; 
 
 $ b $ if if $ $ imageFileType！=jpg&& $ imageFileType！=png&& $ imageFileType！=jpeg
& & $ imageFileType！=gif）{
 echo对不起，只允许使用JPG，JPEG，PNG和GIF文件。 
 $ uploadOk = 0; 
 
 $ b $ if（$ uploadOk == 0）{
 echoSorry，your file was uploaded。; 
 $ b $ else {
 if（move_uploaded_file（$ _ FILES [fileToUpload] [tmp_name]，$ target_file））{
 echoThe file。 basename（$ _FILES [fileToUpload] [name]）。 已上传。 
} else {
 echo抱歉，上传文件时出现错误。 
} 
}

但我的主要目的是上传 Pdf& Docx 作为用户的输入，而不是图像。

我试图改变但是不能成功。任何链接或至少一个描述与一些链接我可以假设其余的为我工作（我希望如果它是一个重复，但没有问我以相同的方式问）。

$ imagefileType 改成了 $ fileType ，有用！！我刚刚跳过了图像检查，如下面的注释部分所示。即使不确定是否需要pdf / doc& docx不像图像。我很感激如果有人提供了额外的信息，我已经跳过了，或者已经很好了@ bxN5 @Ravinder Reddy。

这是简单的。

 <？php 
 $ target_dir =uploads /; 
 $ target_file = $ target_dir。基名（$ _ FILES [ fileToUpload] [ 名称]）; 
 $ uploadOk = 1; 
 $ fileType = pathinfo（$ target_file，PATHINFO_EXTENSION）; 
 / * 
 if（isset（$ _ POST [submit]））{
 $ check = getfilesize（$ _ FILES [fileToUpload] [tmp_name]）; 
 if（$ check！== false）{
 echoFile is a image  - 。 $ check [mime]。 ; 
 $ uploadOk = 1; 
} else {
 echo文件不是图像。 
 $ uploadOk = 0; 
 
 
 $ b if（file_exists（$ target_file））{
 echoSorry，file already exists。; 
 $ uploadOk = 0; 
 
 if（$ _FILES [fileToUpload] [size]> 500000）{
 echoSorry，your file too large。; 
 $ uploadOk = 0; 
 
 if（$ fileType！=pdf&& $ fileType！=doc&& $ fileType！=docx）{
 echo对不起，只允许PDF，DOC和DOCX文件。; 
 $ uploadOk = 0; 
 
 if（$ uploadOk == 0）{
 echoSorry，your file was not uploaded。; 
} else {
 if（move_uploaded_file（$ _ FILES [fileToUpload] [tmp_name]，$ target_file））{
 echoThe file。 basename（$ _FILES [fileToUpload] [name]）。 已上传。 
} else {
 echo抱歉，上传文件时出现错误。 
} 
}

I have an example code below working for images as user's input,

<?php
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);

if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check !== false) {
        echo "File is an image - " . $check["mime"] . ".";
        $uploadOk = 1;
    } else {
        echo "File is not an image.";
        $uploadOk = 0;
    }
}

if (file_exists($target_file)) {
    echo "Sorry, file already exists.";
    $uploadOk = 0;
}

if ($_FILES["fileToUpload"]["size"] > 500000) {
    echo "Sorry, your file is too large.";
    $uploadOk = 0;
}

if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
    echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
    $uploadOk = 0;
}

if ($uploadOk == 0) {
    echo "Sorry, your file was not uploaded.";

} else {
    if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
        echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
    } else {
        echo "Sorry, there was an error uploading your file.";
    }
}
?>

but my main intention is to upload Pdf & Docx as user's input this time instead of images.

I tried to change but couldn't succeeded. Any link or at least a description with a couple of links I can assume the rest works for me (I hoped if it's a duplicate but not asked the same way I guess).

解决方案

Basically, I just changed all $imagefileType to $fileType and it works!! I just skipped the image check as shown with the comment section below. Even not sure if it is needed for pdf/doc & docx unlike image. I appreciate If anyone provide additional information I skipped or it's already fine this way @bxN5 @Ravinder Reddy.

It's just simple as is.

<?php
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$fileType = pathinfo($target_file,PATHINFO_EXTENSION);
/*
if(isset($_POST["submit"])) {
    $check = getfilesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check !== false) {
        echo "File is an image - " . $check["mime"] . ".";
        $uploadOk = 1;
    } else {
        echo "File is not an image.";
        $uploadOk = 0;
    }
}
*/
if (file_exists($target_file)) {
    echo "Sorry, file already exists.";
    $uploadOk = 0;
}
if ($_FILES["fileToUpload"]["size"] > 500000) {
    echo "Sorry, your file is too large.";
    $uploadOk = 0;
}
if($fileType != "pdf" && $fileType != "doc" && $fileType != "docx") {
    echo "Sorry, only PDF, DOC & DOCX files are allowed.";
    $uploadOk = 0;
}
if ($uploadOk == 0) {
    echo "Sorry, your file was not uploaded.";
} else {
    if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
        echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
    } else {
        echo "Sorry, there was an error uploading your file.";
    }
}
?>
