Check if Internal URL or External URL

I've setup a Go_To filed in Category DB.
I call this <%Go_To%> somewhere in the categories to direct the user to INTERNAL CATEGORY or EXTERNAL WEBSITE based on what I put as a value in the field.
Now, if I put a value 123 or 12/4/123 in the Go_To field, then the link where I call it from will go to:
<%config.build_root_url%>/<%Go_To%>/index.html .. then becomes
http://www.mydomain.com/12/4/123/index.html which is valid reference to internal category.

but, if I want the link to go to an external site (http://www.yahoo.com/) , then I specify the site URL in Go_To field... but this will cause a dead link
http://www.mydomain.com/http://www.yahoo.com/index.html

My question, what would be the Perl code that I should use inside category.html template to make this work... (I can modify the way I call the Go_To filed... but I do not like this way, then I need to put long URL in the Go_To field...)
something like ...

If the call to an internal page/category (or if it does not start with "http://www") then
<%config.build_root_url%>/<%Go_To%>/index.html
else:
<%Go_To%>
endif;

Thank you
Mark

Hi,

Try:

Code:
<%if URL contains 'http://'%> 
  <a href="<%config.db_cgi_url%>/jump.cgi?ID=<%ID%>" target="_blank"> 
<%else%> 
  <a href="<%config.build_root_url%>/<%URL%>"> 
<%endif%>

Cheers

Re: [Andy] Check if Internal URL or External URL In reply to

Sorry Andy... maybe I did not clarify it enough...but where would the [Go_To] field value be read... as I am checking the content of this field to see if it has "LINK ID" or a "CATEGORY ID"

The Go_To field is located in the Category db (when I add category to the db, I specify the value of the Go_To field there: Category > Add ).

Shouldn't I be checking the value of the Go_To field!

can I do something like this.. (but I am missing the right code to do that)

Code:

<%if Go_To contains 'ID='%>        /* if Go_To is an internal link in links db so the value in Go_To is something like "ID=143" (the link id) */ 
      <a href="<%config.db_cgi_url%>/jump.cgi?<%Go_To%>" target="_blank">   

<%elseif Go_To is a number %>    /* if Go_To is a numeric value, then that value is the category_id from categories db */ 
     <a href="<%config.build_root_url%>/<%URL%>">  

<%else%>                                      /* go to anywhere specified in the Go_To field... like http://www.yahoo.com/  
     <%Go_To%> 
<%endif%>

Thanks much again ..
Mark

Hi,

I don't think you can do numberical comparisons with the tempalte system (so "is number" wouldn't work =))

Re: [Andy] Check if Internal URL or External URL In reply to

Then how do I use your code, but putting Go_To into picture...
Means.. I do not see Go_To in your code, should I replace URL with Go_To in your code.

Thank you
Mark

Re: [Mark2] Check if Internal URL or External URL In reply to

Can you give me some REAL values, which you have in Go_To? Bit hard to work out really what you are using ;)

Re: [Andy] Check if Internal URL or External URL In reply to

I usually put in Go_To something like:
8
then the the link in the category template will look like:
http://www.mydomain.com/8/index.html
(I am using category ids instead of category names when the system runs)

or I put something like this:
13/143

This also means go to category 13/143 in my site...
http://www.mydomain.com/13/143/index.html

but what I want to do is to also allow for external links like: http://www.yahoo.com so if I put this URL in the Go_To field... then the link in the category template will take you to yahoo.com ...
the problem I am calling the Go_To field with <%config.build_root_url%>/<%Go_To%>/index.html
so you see that if I put an external URL, then this link will be killed.

The other thing.... if the external link exists already in the Links DB, then the Go_To field should be able to handle it ... something like jump?id=<%ID%>

So the code that I wrote would be good to use but it is not formatted correctly... any suggestion...

Thanks much Andy..

Re: [Mark2] Check if Internal URL or External URL In reply to

This should probably work then:

Code:
<%if Go_To contains 'http://'%> 
  <a href="<%Go_To%>" target="_blank"> 
<%else%> 
  <a href="<%config.build_root_url%>/<%Go_To%>"> 
<%endif%>
