Dat is momenteel mijn code,
maar nu slaat hij de foto's te groot op,
de foto's zouden max 500px bij 300px mogen zijn waardoor deze wel sneller worden met laden,
kan iemand mij vertellen hoe ik dat het beste kan doen?

hier ook meteen de fieldbyid functie:

function fieldById($id,$field,$value)
{
mysql_query("UPDATE `profiel` SET `".$field."` = '".$value."' WHERE `id` = '".$id."' ;");
}
{
mysql_query("UPDATE `profiel` SET `".$field."` = '".$value."' WHERE `id` = '".$id."' ;");
}
Als ik het dus goed heb, sla je de foto op in een tabel als een BLOB? Ten strengste af te raden, daar is een database niet voor bedoeld...
Door eerst te kijken of het geuploade bestand een geldig plaatje is, kun je hem vervolgens verkleinen. Houd er wel rekening mee, dat als je een fixed breedte én hoogte meegeeft, je de foto uit z'n proporties haalt.
Ik denk dat je hier wel wat mee kunt: site:phphulp.nl foto upload resize ~ 54 resultaten! :-)
