Use instance:

Copy Code code as follows:

Include ' uploaded.model.php ';
$U = new Uploadmodel ();
$U->target = '/tmp/';
$U->exts = ' jpg,gif ';
$U->maxsize = 1024*275; 275KB
$U->save ();
$files = $U->getfiles ();
Print_r ($files);
Include ' uploaded.model.php ';
$U = new Uploadmodel ();
$U->target = '/tmp/';
$U->exts = ' jpg,gif ';
$U->maxsize = 1024*275; 275KB
$U->save ();
$files = $U->getfiles ();
Print_r ($files);

examples of use in Mayfish:

Copy Code code as follows:

Public function up ()
{
$U = M (' SYS ', ' upload ');
$U->target = '/tmp/';
$U->exts = ' jpg,gif ';
$U->maxsize = 1024*275; 275KB
$U->save ();
Header (' location:/?a=upload ');
}
Public function up ()
{
$U = M (' SYS ', ' upload ');
