每次将记录插入表格时,我都会使用以下PHP代码发送电子邮件。
<?php
$latitude = $_GET['latitude'];
$longitude = $_GET['longitude'];
$uid = $_GET['uid'];
$type = $_GET['type'];
$server = "itp.db.8307610.hostedresource.com";
$username = "abc";
$password = "xyz";
$database = "abc";
$query = "INSERT INTO gps (latitude, longitude, uid, type) VALUES ($latitude, $longitude, $uid, '$type')";
$query1 = "SELECT email FROM musers WHERE uid = $uid";
$result = mysqli_query($link,$query1) or die("query error".mysqli_error());
$email = mysqli_fetch_array($result, MYSQLI_ASSOC);
@mail("$email","New record added","A new record has been added,"From: info@xyz.com");
$link = mysqli_connect($server, $username, $password) or die ("error connecting to database");
mysqli_select_db($database, $link);
mysqli_query($query, $link) or die("query error");
mysqli_query($query1, $link) or die("query error");
mysqli_close($link);
echo "SUCCESS\n";
?>
这没有问题。我已经对电子邮件ID进行了硬编码 如何根据以下查询从musers表动态添加电子邮件。
select email from musers where uid = $uid;
编辑:我在进行更改后收到以下错误消息。
警告:mysqli_query()要求参数1为mysqli,在第12行的/home/content/i/t/p/itp/html/data/email.php中给出为null
警告:mysqli_error()预计在第12行的/home/content/i/t/p/itp/html/data/email.php中给出了1个参数0 查询错误

$result = mysqli_query($link,$query1) or die("query error".mysqli_error());
$email = mysqli_fetch_array($result, MYSQLI_ASSOC);
mail($email['email'],"you@yourdomain.com","message");

有很多问题:
1°您正在尝试在连接数据库之前执行查询。
2°你没有正确地关闭你的琴弦......
尝试此修复:
<?php
$latitude = $_GET['latitude'];
$longitude = $_GET['longitude'];
$uid = $_GET['uid'];
$type = $_GET['type'];
$server = "itp.db.8307610.hostedresource.com";
$username = "abc";
$password = "xyz";
$database = "abc";
$link = mysqli_connect($server, $username, $password) or die ("error connecting to database");
mysqli_select_db($database, $link);
$query = "INSERT INTO gps (latitude, longitude, uid, type) VALUES ($latitude, $longitude, $uid, '$type')";
$query1 = "SELECT email FROM musers WHERE uid = $uid";
$insert = mysqli_query($link,$query) or die("query error".mysqli_error());
$result = mysqli_query($link,$query1) or die("query error".mysqli_error());
$email = mysqli_fetch_assoc($result);
@mail($email['email'],"New record added","A new record has been added","From: info@xyz.com");
mysqli_close($link);
echo "SUCCESS\n";
?>
但是,正如一些人已经提到的那样:准备你的陈述或逃避你的意见......
