Uploading & Renaming files??

[Lee_W]

Hi guys,

On my Intranet I want users to be able to upload files which can have various file names but when uploaded into a specific directory I want the files to have the same name such as 'pricing.pdf'.

This is so that if a new pricelist is available & uploaded it will automatically overwrite the existing one.

How would I go about this?

I know how to upload a file but don't know how to rename it.

move_uploaded_file()
you can set any name you like

This is the script I have written: -

<?php
if (array_key_exists('upload', $_POST))
{
//define constant for upload folder
define('UPLOAD_DIR', 'C:/htdocs/panasonic_pricing/');

//replace any spaces in original filename with underscores
//at the same time, assign to a simpler variable
$file = str_replace(' ', '_', $_FILES['panasonic_pricelist']['name']);

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

?>[/B]

Now, where would I enter the filename I want to use because if I change 'name' or 'tmp_name' the script won't work & returns an error?

[dagon]

bool move_uploaded_file ( string $filename , string $destination )

set the destination file name in your case $file

Sorry Dagon.

Can you show me how I would do this in my script?

I'm completely new to all this & still very much a beginner.

<?php
if (array_key_exists('upload', $_POST))
{
//define constant for upload folder
define('UPLOAD_DIR', 'C:/htdocs/panasonic_pricing/');

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

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

Hi Dagon,

Thanks for your help.

Is there a way of inspecting the array & extracting just the filename & changing that so it keeps the MIME type the same as because sometimes the type of file can vary from an xls to a PDF file?

[dagon]

The mime type will still be set in the $_FILES array. all the above code does is set a new file name to write to.

[Lee_W]

But what if I rename the file pricelist.pdf like you have in your example & the file type being uploaded is an excel file?

[katsurace]

$type_arr=explode(".",$FILES['panasonic_pricelist']['name']);
$type=$type_arr[count($type_arr)-1];
$file_name="pricing".".".$type;
move_uploaded_file($FILES['panasonic_pricelist']['tmp_name'],"../your_directory/$file_name");

[katsurace]

let me know if still it doesn't work
