[mapguide-users] Need help with one specific function

[Jackie Ng]

You use the DigitizePoint(func) function of the mapframe.

For the "func" argument supply a reference to a handler function. 

The handler function will receive a point object from the user's input,
which you can then invoke a server-side script passing in your digitized
point as a parameter

Then on the server side, create your point object from the parameters and
add an MgInsertFeatures object containing this point to a feature command
queue. Call UpdateFeatures() on the command queue and your point should be
inserted into the Feature Source.

So step 1 should really be:

Create a handler function for the DigitizePoint() method. This should invoke
your php script.

eg: 

function PointDigitized(point)
{
     //Call your php script passing point.x and point.y
}

Step 2 is fine. 
Step 3 should then be:

call mapFrame.DigitizePoint(PointDigitized); 

Which will start the whole process.

Hope that helps.
