rename the uploladed file

[Anon]

Hey!

I´ve seen on some big news engine that the pics that´s are shown with the news have filenames like 0000123.jpg and the next one 0000124.jpg?

I would like to when i submit a new story with a picture, the picture would be given the highest available number in the /newsimage folder on the website. Then offcours the news data is saved in mysql database and the name of the image filename with it.

Does anyone know what i´m talking about?

What syntaxes i could use to create a code to do this or some code example?

That would be greatly appreciate 🙂

When you copy the file from the /tmp upload directory to where it will be residing, you can give the copy whatever name you like.

Or of course you could look up www.php.net/rename

The question of what to name it to is more interesting:

$imagedir=opendir('/newsimage');
$highestnum='0000000';
while(false!==($file=readdir($imagedir)))
{
$file=str_replace('.jpg','',$file); //We'll assume we always have JPEGs.
if(strcmp($highestnum,$file)<0)
{
$highestnum=$file;
}
}
//Strip leading zeros that may cause grief (cf. http://www.php.net/manual/en/language.types.integer.php):
$shortnum=preg_replace('/^{0+/','',$highestnum);}

if($shortnum==''){//Oops! stripped all of them!
$shortnum='0';
}
//Get the next number up
$shortnum++;

$newfilename=sprintf('%07d.jpg',$shortnum);
