[mapserver-users] basic search question

[Brian Fischer]

Basically you have to add a mapextent to the URL, couple of different
options to construct the map extent.

1.)	&mapxy=[shpmid]&buffer=5000
2.)	&mapext=[shpext]
3.)	&mapext=[shpminx]+[shpminy]+[shpmaxx]+[shpmaxy]

ok, if I want to display just 1 item, say a parcel.....how would I blow
it
up to full extent?

This is what is working, I can search my sql database by person's name
and
get the parcel_id. I can also show on the map were the parcel is using
the
code below.

Now I want to make that little parcel, blow up full screen. Do I have to
set
extents?
