Jerry first of all thanks for helping me so much. Anyway in both cases, both
with getFromMySql and with the addThumbnails functions the array is
populated with photos like like ceci2k600.jpg, ceci2k601.jpg etc.(I hope I
understood your question correctly) thats why the function toonoverzicht
works correctly in both cases. But as I said, with the getFromMySql
function some info is lost when one photo is shown. In my first posting I
didn't want to post a too large piece of code but now I think it is better
to post it completely. I have tried to make it as modular as possible but I
must admit I am not completely successfull in it. All kind of suggestions
are welcome of course :)
<?php class fotoAlbum
{
var $tmPrefix;//thumbnail prefix, by default it is q, I create my
thumbnails with irfanview but I am considering the gdi functions later
var $fotoPagina;//page that contains the script, default is
toonfoto.php
var $toevoeging;
var $foto_array = array();
var $dezePagina;
var $mysql = false; //only used to put an apology online, to show
that there are some errors on it
function __construct($tmPrefix="q", $fotoPagina =
"toonfoto.php",$toevoeging ="")
{
$this->tmPrefix = $tmPrefix;
$this->fotoPagina = $fotoPagina;
$this->toevoeging = $toevoeging;
}
function getFromMySql($bestandspatroon)
{
$this->mysql = true;
$db = mysql_connect("server", "login","password");
mysql_select_db("database",$db) or die ("FOUT: OPENEN
DATABASE MISLUKT");
$query = mysql_query("SELECT bestandsnaam from fotos where
bestandsnaam LIKE '{$bestandspatroon}%' order by bestandsnaam ASC",
$db);
while (list($bestandsnaam) = mysql_fetch_row($query))
{
$this->foto_array[] = $bestandsnaam;
}
mysql_close($db);
