这条线有什么问题?
23. $result = mysql_query("INSERT INTO $tbl_name('city_id', 'city', 'state_id') VALUES('NULL, '.$city.","', '4421'') or die(mysql_error())");
每次我都会收到此错误消息:
警告:mysql_query() 期望参数 2 是资源,第 23 行给出的字符串
这是我的完整代码
<?php
// Get values from form
$city = explode(',', $_POST['city']);
//create a loop
if(isset($_POST['city'])) {
$city = explode(',', $_POST['city']);
$n = count($city);
for($i=0; $i<$n; $i++) {
$result = mysql_query("INSERT INTO $tbl_name(city_id, city, state_id) VALUES(NULL, '.$city.","', '4421')") or die(mysql_error());
}
} if($result) {
header('Location: index.html');
}
?>
