[英]SQL won't work? It doesn't come up with errors either
我有PHP函數,該函數檢查是否設置了變量,然后將其添加到我的SQL查詢中。 但是我似乎沒有得到任何結果嗎?
$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);
我試圖在像這樣的列表中調用數據:
$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 $row['text'];
} // end while
有人知道為什么我不檢索任何數據嗎?
while ($row = mysql_fetch_object($result)){
// echo data
echo $row->text;
} // end while
我忘了它不是來自數組!
