SQL wont work? It doesn't come up with errors either
- by Stefan
Hey there,
I have php function which checks to see if variables are set and then adds them onto my sql query. However I am don't seem to be getting any results back!?
$where_array = array();
if (array_key_exists("location", $_GET)) {
$location = addslashes($_GET['location']);
$where_array[] = "`mainID` = '".$location."'";
}
if (array_key_exists("gender", $_GET)) {
$gender = addslashes($_GET["gender"]);
$where_array[] = "`gender` = '".$gender."'";
}
if (array_key_exists("hair", $_GET)) {
$hair = addslashes($_GET["hair"]);
$where_array[] = "`hair` = '".$hair."'";
}
if (array_key_exists("area", $_GET)) {
$area = addslashes($_GET["area"]);
$where_array[] = "`locationID` = '".$area."'";
}
$where_expr = '';
if ($where_array) {
$where_expr = "WHERE " . implode(" AND ", $where_array);
}
$sql = "SELECT `postID` FROM `posts` ". $where_expr;
$dbi = new db();
$result = $dbi->query($sql);
$r = mysql_fetch_row($result);
I'm trying to call the data after in a list like so:
$dbi = new db();
$offset = ($currentpage - 1) * $rowsperpage;
// get the info from the db
$sql .= " ORDER BY `time` DESC LIMIT $offset, $rowsperpage";
$result = $dbi->query($sql);
// while there are rows to be fetched...
while ($row = mysql_fetch_object($result)){
// echo data
echo $row['text'];
} // end while
Anyone got any ideas why I am not retrieving any data?
