Upload Script That Does A Special Rename

storyboo · Jun 25, 2009

Hi,

I'm trying to create an upload utility in my own shopping cart software that allows the store owner to upload buttons for the cart system. For each button I have made a default .png image and store it in a folder at root/images/buttons. I want whatever png image is uploaded to be renamed to a specific name like go.png. So they could upload any image thats a png and it will automatically rename it to go.png. This will overwrite the current go.png in the folder and their button will be updated. I do not want to do a database storage of images becuase the database is already 61 tables and I need to cut down on the size of things and just make it simple. Here's the code I have so far. but I am getting the error:

Warning: rename($file_name,go.png) [function.rename]: No such file or directory in /home/papermom/public_html/manager/settings/buttons2.php

<?php


// Your file name you are uploading
$file_name = $HTTP_POST_FILES['ufile']['name'];


rename( '$file_name', 'go.png' );

$path= "../images/buttons/";
if($ufile !=none)
{
if(copy($HTTP_POST_FILES['ufile']['tmp_name'], $path))
{
echo "Successful<BR/>";

echo "File Name :".$new_file_name."<BR/>";
echo "File Size :".$HTTP_POST_FILES['ufile']['size']."<BR/>";
echo "File Type :".$HTTP_POST_FILES['ufile']['type']."<BR/>";
}
else

echo "Error";
}
}

php wont parse variables in single quotes:

rename( '$file_name', 'go.png' );

try:

rename( $file_name, 'go.png' );

Did that change and now I get this error

Warning: rename(,go.png) [function.rename]: Inappropriate ioctl for device in /home/papermom/public_html/manager/settings/buttons2.php on line 29

That means that $file_name is empty. I dont see any checks in your script that file is actually uploaded.

And use $_FILES instead of $HTTP_POST_FILES. Long version has been deprecated for years already. Also use [man]move_uploaded_file[/man] instead of copy.

storyboo · Jun 25, 2009

What if I changed my php to:

<?php
if (array_key_exists('upload', $_POST))
{
//define constant for upload folder
define('UPLOAD_DIR', 'images/buttons/');

//replace any spaces in original filename with underscores
//at the same time, assign to a simpler variable
$file ='go.png';

//move the file to the upload folder and rename it
move_uploaded_file($_FILES['somethinggoesherenotsurewhat']['tmp_name'], UPLOAD_DIR.$file);
}
?>

storyboo · Jun 25, 2009

Ok I changed the php to this

if (array_key_exists('upload', $_POST))
{
//define constant for upload folder
define('UPLOAD_DIR', 'images/buttons/');

//replace any spaces in original filename with underscores
//at the same time, assign to a simpler variable
$file ='go.png';

//move the file to the upload folder and rename it
move_uploaded_file($_FILES['upload']['tmp_name'], UPLOAD_DIR.$file);
}

And there are no errors...but there is also nothings in my upload directory lol...I think I'll also need it to confirm the size and file type so that they dont try to upload a go.gif ...that wont work...

cahva · Jun 25, 2009

You can check straight using $FILES:

if (isset($_FILES['ufile']['tmp_name']))
{
    ...

Ok now what I have don instead of posting echo's for success...I echoed the image itself so I can see right away if it was overwritten with x.gif. No luck arg....so frustrating!! lol

<?php
if (isset($_FILES['ufile']['tmp_name']))
{ 
$UPLOAD_DIR ='/images/buttons/';
$file ='go.gif';
move_uploaded_file($_FILES['ufile']['tmp_name'], UPLOAD_DIR.$file);
}
?>


<table width="530" border="0" align="center" cellpadding="0" cellspacing="1" bgcolor="#CCCCCC">
<tr>
<form action="buttons2.php" method="post" enctype="multipart/form-data" name="form1" id="form1">
<td>
<table width="100&#37;" border="0" cellpadding="10" cellspacing="1" bgcolor="#FFFFFF">
<tr>
<td width="20%"><strong>Go Button </strong></td>
<td width="50%"><input name="ufile" type="file" id="ufile" size="25" /></td>
<td width="13%"><input type="submit" name="Submit" value="Upload" /></td>
<td width="17%"><div align="center">
  <?php
echo "<img src=\"/images/buttons/go.gif\" title=\"Go Button\" alt=\"Go Button\" />"; 
?>
</div></td>
</tr>
</table>
</td>
</form>
</tr>
</table>

Boy that php sure does like a little skimpy.... Does anyone have any ideas?

cahva · Jun 25, 2009

Check what's in the $FILES array after upload:

print_r($_FILES);

There is $_FILES['ufile']['error']. If its anything else than 0 then there was problem uploading it.
Error codes can be found here

Ok.. I spotted the problem:

move_uploaded_file($_FILES['ufile']['tmp_name'], UPLOAD_DIR.$file);

There is $ sign missing in UPLOAD_DIR so it should be $UPLOAD_DIR. In earlier script you defined it but in the latest you assigned it to a variable.

I'll do this right away...ill report back in a minute yay!

Remember that when you set the upload dir and use /images/buttons/ it is absolute to the server. So if using absolutepath you should use something like:

$UPLOAD_DIR ='/home/papermom/public_html/images/buttons/';

..or use relative path to your script eg "../../images/buttons"

storyboo · Jun 25, 2009

sweet that did it!!! It all works perfect now it the simlified form!! Now I just need to make it only accept png's lol Thank you Cahva!!

scrupul0us · Jun 25, 2009

and you can do that by verifying the files' mime type... google or search this forum and youll find some reusable code for doing that

storyboo · Jun 25, 2009

ok...question... How is it that on the server in the images/buttons directory...my test go.gif file is the same however on the php page I made where it echos the image in the html form like

  <?php
echo "<img src=\"/images/buttons/go.gif\" title=\"Go Button\" alt=\"Go Button\" />"; 
?>

It has the new image I uploaded? How can that be? Is it showing from the tmp?

storyboo · Jun 25, 2009

also another important thing to mention...my test go.gif image is 1.07 kb and when i upload the new x.gif image to be renamed to go.gif and replace that image...it changed the kb to 19.55kb for example. However when i view the image from file manager on cpanel....its the same image.

storyboo · Jun 25, 2009

nevermind....probably a problem with file manager in cpanel becuase the template for the website calls for that same button and voila..its my new uploaded button!

When I get the file type restriction I will post a final reply and close the thread and resolved. I hope that someone else will find it helpful when wanting to do the same thing! Sometimes its really hard to find some code that is xactly what you need Thanks to everyone so very much for the hard work in helping me solve this I have learned a ton!!

cahva · Jun 25, 2009

If you put that image straigth in to your url (eg. http://www.yourdom.com/images/buttons/go.gif) does it show? Press refresh(ctrl+F5) just in case so it doesnt come from browser cache.

storyboo · Jun 26, 2009

yep it shows up. I think becuase i've had my cpanel and file manager open straight for days and days working on my new cart system...it gets 'stuck' lol.
