我正在尝试使用以下逻辑将一些表单数据放入两个数据库表中
INSERT
表中的新监视'watchlists'
列表SELECT watchlist_id
表中的新关注'watchlists'
列表WHERE watchlist_name = $watchlist_name
(刚刚创建的新关注列表的名称)和user_id = $user_id
INSERT watchlist_id
(从上一个查询中选择)ANDfilm_id
到'watchlist_films'
表中
我正在使用以下代码,但该过程似乎在运行SELECT
查询时中断。在数据库中创建了新的监视列表,但它不会选择新监视列表的 ID,也不会运行代码的最后一部分。
if ($db_server) {
// Add new Watchlisth
if (!empty($watchlist_name)) {
$watchlist_name = clean_string($watchlist_name);
$watchlist_description = clean_string($watchlist_description);
mysql_select_db($db_database);
// Create new Watchlist
$insert_new_watchlist = "INSERT INTO watchlists (user_id, name, description, category) VALUES ('$user_id', '$watchlist_name', '$watchlist_description', '$watchlist_category')";
mysql_query($insert_new_watchlist) or die("Insert failed. " . mysql_error() . "<br />" . $insert_new_watchlist);
// Select new Watchlist's ID
$select_new_watchlist_query = "SELECT watchlist_id FROM watchlists WHERE name = " . $watchlist_name;
$new_watchlist_id = mysql_query($select_new_watchlist_query);
// Insert film into new Watchlist
$add_new_film = "INSERT INTO watchlist_films (watchlist_id, film_id) VALUES ('$new_watchlist_id', '$rt_id')";
mysql_query($add_new_film) or die("Insert failed. " . mysql_error() . "<br />" . $add_new_film);
$addWatchlist_good_message = '<div class="alert alert-success">Watchlist created successfully, and film added!</div>';?>
<script>
$('a.add-watchlist').trigger('click');
</script><?php
}
} else {
$addWatchlist_bad_message = '<div class="alert alert-error">Error: could not connect to the database.</div.';?>
<script>
$('a.add-watchlist').trigger('click');
</script><?php
}
require_once("db_close.php");
}
我已经使用以下字符串在 phpMyAdmin 中运行了查询:(SELECT watchlist_id FROM watchlists where name = "LotR"
其中 LotR 是新创建的监视列表的名称)并且效果很好,因为它将我带回监视列表的 ID,这是我想要传递到第二个这两个INSERT
查询。
