我正在尝试执行以下MySQL查询：
SELECT event.event_id, venue.venue_name, venue.alt_venue_name, venue.venue_address1, venue.cross_street, dictionary_city.city_name, venue.zip, dictionary_filter.filter_name, venue.capacity, event.start_date, event.end_date, dictionary_barType.is_ob, dictionary_barType.barType_name, event.barType_time, event.is_food, event.food_type, event.food_time, dictionary_age.age_name, dictionary_age.age_description, event.ticketCo_id, event.ticket_locator, event.ticket_left, event_description.description, event_highlight.highlight, event.event_tag, event.image_flyer, event.image_flyer_310x425, event.image_2, event.image_2_310x208, event.image_3, event.image_3_310x208
FROM event
LEFT JOIN venue
ON venue.venue_id=event.venue_id
LEFT JOIN dictionary_city
ON venue.city_id=dictionary_city.city_id
LEFT JOIN dictionary_filter
ON venue.venueType_id=dictionary_filter.filter_id
LEFT JOIN dictionary_barType
ON event.barType_id=dictionary_barType.barType_id
LEFT JOIN dictionary_age
ON event.event_age_id=dictionary_age.age_id
LEFT JOIN event_highlight
ON event_highlight.event_id=event.event_id
LEFT JOIN event_description
ON event_description.event_id=event.event_id
WHERE event.event_id="".$event_id."";
当我在PhP Admin中运行查询时，它工作正常，但当我将代码添加到我的网站时，我收到以下错误
“警告：mysql_fetch_array（）期望参数1是资源， 给出的布尔值 /home/nye/public_html/theballdrop.com/templates/template.event.php on 第29行 - 更多信息： http://theballdrop.com/new-years-eve-madame-tussauds/#sthash.880jgbaa.dpuf“
它引用的查询是"if ($row = mysql_fetch_array($result)){"
我不知道从哪里开始。这应该在单个页面上显示来自多个表的信息。 $ event_id是变量，特定事件ID将确定要为该特定事件页面显示的信息。
请帮忙。

将数据库选择添加到连接脚本，如下所示：
<?php
$hostname = "localhost";
$username = "{username]";
$password = "[pass]";
$dbname = "nye_newyears";
$con = mysql_connect("$hostname", "$username", "$password");
if (!$con) {
die('Could not connect: ' . mysql_error());
}
if(!mysql_select_db($dbname)) {
die('Could not find or access database ' . $dbname);
}
?>
答案 1 :(得分：0)
event是mysql中的关键字。所以将它包装在引号（`）中并尝试。
在浏览器中回复您的$sql并将其粘贴到phpmyadmin并执行，如果有的话，您将收到特定的错误。
答案 2 :(得分：0)
首先，检查服务器中的MySql表名。有时某些主机会在表名上添加前缀。
您应首先检查$ result对象
if(!$result){
exit(mysql_error());
}else{
if ($row = mysql_fetch_array($result)){
// ....
// ...
}
}
答案 3 :(得分：0)
谢谢大家的帮助。 Knittl你是对的!!!
我将以下代码添加到mysql-connect文件中：
if(!mysql_select_db($dbname)) {
die('Could not find database ' . $dbname);
}
非常感谢你。
