Hi I got a cycling site where we are using www.openrunner.com
to insert the cycling course , you can insert the course using google map.
This is an example of a course that they insert that shows up on the site.
<iframe width="700" height="400" frameborder="0" src="http://www.openrunner.com/displayRoute.php?id=404674&w=650&h=300&k=1&m=0"></iframe>
what I would like to do to have everyone inserting the same size is
to have the width="700" height="400" always at 700 and 400
and this part
always at w=650 and h=300
I was wondering is there a way to do this with str_replace if someone inserted other values
