Question

I run this function and the value of the post form doesn’t insert into the DB. I’m not getting any error messages but I checked and saw that $this->user_id is populating. Am I missing something else?

function senddata () {
    $con = mysql_connect("localhost","root","XXXXX");
    if (!$con)
        {
    die('Could not connect: ' . mysql_error());
        }
        mysql_select_db("user", $con);
        $sql="INSERT INTO profile (collegemajor) VALUE('$_POST[major]') WHERE userid=$this->user_id";

    mysql_close($con);

    }

First of all, I don’t see the mysql_query() – the function to execute the query.

It seems like the problem is here:

$sql="INSERT INTO profile (collegemajor) VALUE('$_POST[major]') WHERE userid=$this->user_id";

Use $sql="INSERT INTO profile (collegemajor) VALUE('$_POST[major]'); instead.

The code:

    function senddata () {
        $con = mysql_connect("localhost","root","XXXXX");
        if (!$con)
            {
        die('Could not connect: ' . mysql_error());
            }
            mysql_select_db("user", $con);
            $sql="INSERT INTO profile (collegemajor) VALUE('$_POST[major]');";
        mysql_query( $sql , $con );

        mysql_close($con);

        }
