Re: Class's and Variables

prob not conventional but i usually set the connection outside my classes then i import the connection id inside the constuctor so my connection object pointer from my db class is $db then inside the constructor it would look like $this->db = $GLOBALS['db']; so copy file would look like function CopyFile() { $sql = "INSERT INTO images ( i_base64 ) VALUES 'myImage');"; $this->db->query($query); $this->db->close(); } > Hi, > > I've got a PHP class off the web and there's a change > or two I'd like to make to one of the functions. > > So I have a question on adding private variables. > Let's say I want to connect to my database, Postgresql, > is it OK to just add the required variable's to the > method itself or should the variable's be set at the > start of the class. > > I hope my code example below helps explain my question: > > class UploadImage > { > var $image; > > function UploadImage($image) > { > $this->image=stripslashes($image); > } > > function CopyFile() > { > $conn = pg_connect("dbname=oasis_net"); > $sql = "INSERT INTO images ( i_base64 ) VALUES 'myImage');"; > $res = pg_exec($conn,$sql); > $conn = pg_close($conn); > } > } > > Is it OK to set the $res variable in CopyFile() like above or > should it be set where the $image variable is set. > > Thanks heaps. > Regards > Rudi. > > > > > > > > > > > > > > > > -- > PHP General Mailing List (http://www.php.net/) > To unsubscribe, visit: http://www.php.net/unsub.php
