Incorrect integer value: '' for column error

Question

I am getting \'Incorrect integer value: \'\' for column country_id\'. Sometimes my dropdown is hidden in the form. So I am not sure how to handle this situtation. Here is my cod

Answer 1

You are adding ' to the $countryId value. Since an integer is expected, you don't have to use them. Try this:

$countryId = isset($_POST['country']) ? (int)$_POST['country'] : 0;

$inserSQL = "INSERT INTO Table1(country_id) VALUES($countryId)";

$Result1 = mysql_query($inserSQL ) or die(mysql_error());
