Yes, that is the way to go. Although, you PHP page can redirect to the
ajaxviewer,
so you do not have to fiddle with the iframe src, but just point at the
startup PHP page.
There are two other options:
1. handle "onload" in javascript and zoom there
2. modify the ajaxviewer to read the new center/scale info
Option number 1 has a drawback, as you will request two initial images.
Option number 2 is going to give you headaches when you upgrade.
I'm not a PHP expert, but I'm sure someone else has the correct code.
Are there any steps that you want explained from the link you provided?

This is an old thread but very important for me right now.
I want to set the initial view (coords and scale) of a map and have been
struggling conceptually with how to implement this. I have a page containing
an iframe. The iframe's src attribute is the path to a MapGuide web layout,
e.g.
/mapguide/mapviewerajax/?WEBLAYOUT=Library://Trial/Trial.WebLayout&LOCALE=en
Originally I thought that I would need to interrupt the initial map load to
dabble with the web layout's XML, but http://tinyurl.com/6jkdyj talks about
creating a copy of the web layout, making the desired changes, and saving it
to the session, and using the copy. So would the following be the right way
to go?
1. Change the main page's iframe to have no src attribute specified
2. On page load, call a PHP script to create a web layout in the session
based upon the one in the library
3. Dynamically set the iframe's src to be something like
"...?WEBLAYOUT=Session://..."
I hope one of you seasoned MapGuide developers can put me straight on this!
Thanks for your time.
Stuart
