When is use the following code without mysql_real_escape_string, works fine. I simply trying to grab a text string that may have apost. from an input form and format it to p
Try mysqli_real_escape_string
instead.
You must connect with database first before using Warning: mysql_real_escape_string()
No, you shouldn't mix mysql and mysqli.
Use here instead of mysql_real_escape_string($var)
:
$con->real_escape_string($var);
You're at risk of MySQL injections. Never insert data directly to a database without some sort of projection first. It's a major security risk. Also use mysqli_real_escape_string instead, and note that your $_POST[webSite] is unprotected.
Also, your error means that your database details are not correct.
A working code example that is a solution to this problem is available here:
