weird uploading file

begeiste · #1 Sep 18th, 2007, 19:22

Hi,

I was uploading a very small text file (sqltext.txt)from a folder(A) and try to copy it to the another folder(B)where is the same folder with the fileupload.php and file_upload.html. After uploading the sqltext.txt, the browser displays nothing, neither a error message nor any message. Not sure what happened? Would you mind helping me for this problem? Any inputs will be much appreciated!!!

HTML: Select all

<form name="form1" method="post" enctype="multipart/form-data" action="fileupload.php">
    <p>Name:<input type="text" name="uname" /></p>
    <p>Choose file you want to upload:</p>
    <p><input type="file" name="ufile" /></p>
    <p><input type="submit" name="submit" value="Start to Upload" /><input name="reset" type="reset" value="Reset" /></p>
</form>

PHP: Select all


<?php
//receiving uploaded file from client side
echo $_POST['uname']. " Hello:<p>";
$error_msg=$_FILES['ufile']['error'];
$fname=$_FILES['ufile']['name'];
$tmpname=$_FILES[['ufile']['tmp_name'];
$fsize=$_FILES['ufile']['size'];
$ftype=$_FILES['ufile']['type'];

//if to determining file be successfully uploaded
    if($error_msg){
        echo "<font color='red'> File has not been uploaded successfully!</font><p>";
        echo "The relevanted error is: ".$error_msg;
    }else{
        //file uploaded successfully
        echo "Already received uploaded file, file name is: ".$fname."<br>";
        echo "File name is the server position as temp is: ".$tmpname."<br>";
        echo "Uploaded file size is: ".$fsize."<br>";
        echo "Uploaded file type is: ".$ftype."<br>";
        echo "<hr>";
        
        //save the uploaded file to the respective folder
        $success=copy($tmpname,'newtext.txt');
        
        if($success){
            echo "File has been copied successfully<br>";
            echo "New file path and directory name is below: <br>";
            echo realpath('newtext.txt')."<p>";
            
        //delete this uploaded file
        unlink($tmpname);
        }else{
        
            echo "<font color='red'>Can not copy this file !</font>";
        }
    
    }
?>

Can you check your error log to see if there is any PHP error occurring.

Also a few hints

It is is much more secure to use is_uploaded_file() and move_uploaded_file() in PHP.

So you could change your code to be

PHP: Select all


<?php

//receiving uploaded file from client side

echo $_POST['uname']. " Hello:<p>";

$error_msg=$_FILES['ufile']['error'];

$fname=$_FILES['ufile']['name'];

$tmpname=$_FILES[['ufile']['tmp_name'];

$fsize=$_FILES['ufile']['size'];

$ftype=$_FILES['ufile']['type'];



//if to determining file be successfully uploaded

// Is uploaded file makes sure that the file was uploaded and not a user trying to use HTTP tricks to work with files it shouldn't

    if(!is_uploaded_file($fname)){

        echo "<font color='red'> File has not been uploaded successfully!</font><p>";

        if ($error_msg)

        echo "The relevanted error is: ".$error_msg;

    }else{

        //file uploaded successfully

        echo "Already received uploaded file, file name is: ".$fname."<br>";

        echo "File name is the server position as temp is: ".$tmpname."<br>";

        echo "Uploaded file size is: ".$fsize."<br>";

        echo "Uploaded file type is: ".$ftype."<br>";

        echo "<hr>";

        

        //save the uploaded file to the respective folder

        $success=move_uploaded_file($tmpname,'newtext.txt');

        

        if($success){

            echo "File has been copied successfully<br>";

            echo "New file path and directory name is below: <br>";

            echo realpath('newtext.txt')."<p>";

            

        //delete this uploaded file

        unlink($tmpname);

        }else{

        

            echo "<font color='red'>Can not copy this file !</font>";

        }

    

    }

I can't see what would be causing no output (as script looks okay) unless it's a fatal error.

Hope that helps some.

Thanks so much. There is the problem of duplicated '['

$tmpname=$_FILES[['ufile']['tmp_name'];
