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_query("UPDATE settings SET postsPerPage = $postsPerPage WHERE id = '1'") or die(mysql_error());
mysql_query("UPDATE settings SET style = $style WHERE id = '1'") or die(mysql_error());
Add your multiple columns with comma separations:
UPDATE settings SET postsPerPage = $postsPerPage, style= $style WHERE id = '1'
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?
Also, is style a number or a string? I'm assuming a string, so it would need to be quoted.
