PHP的PDO更新查询变量

Question

I hope someone can point out where I am going wrong with this update, I have tried various ways but just can't seem to get it to work, probably a simple mistake but I just can't seem to find it.

function set_live($row_id, $mobile_number)
{
    global $conn;
    $live = 1;

    $sql = "
     UPDATE 
      connections 
     SET 
      live = :live, 
      voice_number = :mobile_number 
     WHERE 
      id = :row_id";

    $stmt = $conn->prepare($sql);
    $stmt->bindParam(':mobile_number', $mobile_number, PDO::PARAM_INT);
    $stmt->bindParam(':row_id', $row_id, PDO::PARAM_INT);
    $stmt->bindParam(':live', $live, PDO::PARAM_INT);
    $stmt->execute();

    echo "Record edited successfully";
    $conn=null;
}

$conn is the PDO connection which works with SELECT's etc All variables are numbers and all echo OK so are in the function I can run the query with the actual values in phpmyadmin and it works OK

Answer 1

Just replace this line

$stmt->bindParam(':mobile_number', $mobile_number, PDO::PARAM_INT);

with this

$stmt->bindParam(':mobile_number', $mobile_number, PDO::PARAM_STR);

Because the phone number length is more than integer.

Why not try using an Array? That approach may well do the Trick for you:

    <?php
        function set_live($row_id, $mobile_number){
            global $conn;
            $live = 1;
            $sql    = "UPDATE connections SET live=:live, voice_number=:mobile_number WHERE id=:row_id";
            $stmt   = $conn->prepare($sql);
            $params = array(
                "live"          =>$live,
                "mobile_number" =>$mobile_number,
                "row_id"        =>$row_id,
            );

            $stmt->execute($params);
            echo "Record edited successfully";
            $conn=null;
        }
