Image upload rename - removing spaces

[CanMan2004]

Hi all

 

I've written a script to upload a resize an image, but I cant figure out how I can get it to remove all spaces from the filename, the code is

 

if ($_FILES['image']['name'] != '')
{
$randy = random(12);
$uploadImageDir = '../image_upload/activity_uploads/'.$randy.'';
$uploadImage = $uploadImageDir . $_FILES['image']['name'];
$uploadImageFormat = $randy.$_FILES['image']['name'];
if (move_uploaded_file($_FILES['image']['tmp_name'], $uploadImage) )
{
}
$imageupload = $uploadImage;
createthumb($imageupload,$imageupload,767,'','',411);		
}
else
{
print"<script>alert ('There was a problem with your image');</script>";
print"<script>document.location='register.php'; </script>";
}

 

Where would I place a str_replace function?

 

Can anyone help?

 

Thanks

 

Dave

trim($filename);

 

you shoudl also check if the file name already exists if so append something to the basename of the file like '_1'.

So where should I encorporate trim() into my query?

$uploadImage = trim($uploadImageDir . $_FILES['image']['name']);

Hi

 

Thanks, but that doesnt seem to remove any spaces from the filename

$uploadImage = $uploadImageDir . $_FILES['image']['name'];

$uploadImage = str_replace(" ", "_", $uploadImage);

trim only removes spaces from the beginning of the file and the end of the file
