Troubleshooting: Can't seem to Save()


The Save() function should always return the object Id when a Save() is performed. You can use this return value to check whether your object has been properly saved or not. For example, let’s assume you’re trying to insert a User object into your database. You can use the return value of the userid as follows:

PHP:
$user = new User();  //create a user object
if ($user->Save())
{
   echo "user saved successfully!";
}
else
{
  echo "user not saved";
}

Now, if you try saving your user object and see “user not saved”, this means that POG wasn’t able to save the object. To perform further troubleshooting, you can echo out the SQL query that POG is trying to perform on your database during the Save() function. To do this, try modifying the object file as follows:

In the Save() function, locate the 2 lines that have
$query = ....

and modify them to look like this:

echo $query = .....

This will echo out the query that you can manually apply to your database. This should tell you what’s wrong with the query.
