I am trying to get a facebook like link for a dymanic url - http://www.swedishmotors.com/cars/pages/car_search_full_details.asp?id=582

I tried replacing the 582 with <%=rsData("strcarid")%> wihich holds the value.

If you visit the url you can see the error.

Thanks!

<%response.write(Server.URLEncode("http://www.swedishmotors.com/cars/pages/car_search_full_details.asp?id=" & strcarid))%>

 <iframe src="http://www.facebook.com/plugins/like.php?href=<%response.write(Server.URLEncode("http://www.swedishmotors.com/cars/pages/car_search_full_details.asp?id=" & strcarid))%>&amp;layout=standard&amp;show_faces=true&amp;width=450&amp;action=recommend&amp;font=tahoma&amp;colorscheme=light&amp;height=80" scrolling="no" frameborder="0" style="border:none; overflow:hidden; width:450px; height:80px;" allowTransparency="true"></iframe>

I have update my code to URLEncode the link.
When you click the like button at the very bottom of the page, then unlike you get an error in the facebook feed.

You have a " that doesn't have have a matching " here : height=80" , fixing that might fix the problem

if that doesn't work try :

dim url = "http://www.facebook.com/plugins/like.php?href="http://www.swedishmotors.com/cars/pages/car_search_full_details.asp?id=" & strcarid & "&amp;layout=standard&amp;show_faces=true&amp;width=450&amp;action=recommend&amp;font=tahoma&amp;colorscheme=light&amp;height='80' scrolling='no' frameborder='0' style='border:none; overflow:hidden; width:450px; height:80px;' allowTransparency='true'"

<iframe src=<%response.write(url)%></iframe

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Currently I have this:

<iframe src="http://www.facebook.com/plugins/like.php?href=<%response.write("http://www.swedishmotors.com/cars/pages/car_search_full_details.asp?id=" & strcarid )%>3E&amp;layout=standard&amp;show_faces=false&amp;width=450&amp;action=recommend&amp;font=verdana&amp;colorscheme=light&amp;height=35" scrolling="no" frameborder="0" style="border:none; overflow:hidden; width:450px; height:35px; allowTransparency="true"></iframe>

Facebook Error: The page at http://www.swedishmotors.com/cars/pages/car_search_full_details.asp?id=5903E could not be reached.

I do not know where the 3E is coming from? http://www.swedishmotors.com/cars/pages/car_search_full_details.asp?id=590 is the link to my page.

You still have a " without a matching starting quote on the height attribute. colorscheme=light&amp;height=35"

I suggest you use the approach I said in my previous post

I have tried that:

<iframe src="http://www.facebook.com/plugins/like.php?href=
<%response.write(Server.URLEncode("http://www.swedishmotors.com/cars/pages/car_search_full_details.asp?"&(Request.QueryString)))%>&amp;layout=standard&amp;show_faces=false&amp;width=450&amp;action=like&amp;colorscheme=light&amp;height=35" scrolling="no" frameborder="0" style="border:none; overflow:hidden; width:250px; height:35px; allowTransparency="true"></iframe>

I believe the problem is right here: ?"&(Request.QueryString)))%>
It is not pulling the QueryString.

I have also tried this -
dim url
url= "http://www.swedishmotors.com/cars/pages/car_search_full_details.asp?id=" & strcarid
response.write(url)


<--iframe src="http://www.facebook.com/plugins/like.php?href=<%response.write(url)%>3E&amp;layout=standard&amp;show_faces=false&amp;width=450&amp;action=recommend&amp;font=verdana&amp;colorscheme=light&amp;height=35" scrolling="no" frameborder="0" style="border:none; overflow:hidden; width:450px; height:35px; allowTransparency="true"></iframe>

This returns-
<--iframe src="http://www.facebook.com/plugins/like.php?href=http://www.swedishmotors.com/cars/pages/car_search_full_details.asp?id=5903E&layout=standard&show_faces=false&width=450&action=recommend&font=verdana&colorscheme=light&height=35" scrolling="no" frameborder="0" style="border:none; overflow:hidden; width:450px; height:35px; allowTransparency="true">

You still don't have that quote in which is why the string is being closed after the height =35" change it to height='35'
and take out the 3E from <%response.write(url)%>3E

or is that where the href is supposed to end? if so maybe you just need to take out the 3E ?

It seems the iframe now load fine - but the functionality with facebook is not working - you get an error when you click like.  It is like Facebook is not interacting with the url correctly?

The error is coming back as 'The page at http://swedishmotors.com/cars/pages/car_search_full_details.asp could not be reached.', i have no idea but it does seem to be a problem at facebooks end or as you say it is not interacting with the url correctly.

<script src="http://connect.facebook.net/en_US/all.js#xfbml=1"></script><fb:like show_faces="false" width="450" action="recommend"></fb:like>
