PHP:在单个查询中更新多个MySQL字段

问题描述：

我基本上只是想更新表中的多个值.最好的方法是什么?这是当前代码:

I am basically just trying to update multiple values in my table. What would be the best way to go about this? Here is the current code:

$postsPerPage = $_POST['postsPerPage'];
$style = $_POST['style'];

mysql_connect ("localhost", "user", "pass") or die ('Error: ' . mysql_error());
mysql_select_db ("db");

mysql_query("UPDATE settings SET postsPerPage = $postsPerPage WHERE id = '1'") or die(mysql_error());

我要包含的另一个更新是:

The other update I want to include is:

mysql_query("UPDATE settings SET style = $style WHERE id = '1'") or die(mysql_error());

谢谢！

答

添加带有逗号分隔的多列:

Add your multiple columns with comma separations:

UPDATE settings SET postsPerPage = $postsPerPage, style= $style WHERE id = '1'

但是，您没有对输入内容进行消毒??这意味着任何随机的黑客都可能破坏您的数据库.看到以下问题:清除用户输入的最佳方法是什么用PHP?

However, you're not sanitizing your inputs?? This would mean any random hacker could destroy your database. See this question: What's the best method for sanitizing user input with PHP?

此外，样式是数字还是字符串?我假设使用字符串，因此需要将其引号.

Also, is style a number or a string? I'm assuming a string, so it would need to be quoted.
