URL Structure

Hi Everybody, I'm trying to get the name/value pair from url variables.  Lets say I have a url like this: http://someurlhere.com?Src=blahblah&storyID=1234 Now if I do the following I'll get the name/value pair of the URL vars: <cfloop collection=#url# item="urlVar">   <cfoutput>#urlVar# = #url[urlVar]#</cfoutput><br /> </cfloop> My problem is the name element doesn't keep the same case as the actualy url variable name.  Src and storyID gets displayed as SRC and STORYID in the output.  How can I keep the case the same when I loop thru the URL structure?

I don't think you can. CF is case-insensitive for one thing. It looks like case MIGHT be preserved in CGI.QUERY_STRING. So you could try the following: <cfloop list="#CGI.QUERY_STRING#" delimiter="&" index="keyvalue">   <cfoutput>#listFirst(keyvalue,"=")# = #listLast(keyvalue,"=")#</cfoutput> </cfloop> A couple of problems with that, of course: - Any URL variables you've explicitly set (such as with cfparam) or removed won't be accounted for. - You need to care for instances when there is a key but no value. "key1=&key2=a" Why do you need to see your URL variables in their original case?

I'm actually creating a disclaimer page that redirects the users.  So the user sees a disclaimer page indicating they are leaving the site and connecting to an outside site.  Then they get redirected to that site.  For some reason my disclaimer redirect code wasn't working correctly for links that had multiple url variables in it.  It would get cut off after the end of thefirst url variable.  The user wouldn't get redirected to the page intended b/c of this.  For instance lets say a user clicked on a link on my page that went to: http://go.reuters.com/newsArticle.jhtml?type=healthNews&storyID=12037965&src=eDialog/GetContent My page would actually have this as the link http://someurlhere.com/disclaimer.cfm?destination= http://go.reuters.com/newsArticle.jhtml?type=healthNews&storyID=12037965&src=eDialog/GetContent the disclaimer.cfm would look something like this: <cfset destination=url.destination> <script language="JavaScript" type="text/javascript">   <!--   function dspDisclaim(){     setTimeout('window.location.href="#destination#"',10000);   }   //--> </script> Now this worked fine when there wasn't multiple url vars in the original link, but as you can see this reuter link has mutliple vars in it. So to fix it so that all the url vars got included in my redirect i did this: <cfset destination=""> <cfif StructCount(url) GT 1>   <cfset destination = url.destination>   <cfset structDestinationRemove = StructDelete(url, "destination", "true")>      <cfloop collection=#url# item="urlVar">     <cfset destination = destination&"&"&urlVar&"="&url[urlVar]>   </cfloop> <cfelse>   <cfset destination = url.destination> </cfif> This actually recontructed the URL correctly with all the URL vars, but the problem is this particular link is case sensitive and does not work when the url vars got recontructed in uppercases letters. Maybe I'm doing the whole redirect thing incorrectly or theres an easier way.  But if anybody can help me out, I would appreciate it.  Thanks.

You can just parse it as a list of lists. The main list is a list delimited by &. The sub lists are delimited by =. You would need to urlDecodedFormat() on the right hand side. Oh, and the variable itself comes from cgi.query_string.

I think the simplest solution is to uCase the variables when you pass them via the URL.

> I'm trying to get the name/value pair from url variables.   You can't, really. CF doesn't think that's important information, so it doesn't store variable names that way. This is common in case-insensitive programming languages, I suspect. You could, however, examine the query string directly. But why do you need the case of the variable name to be preserved anyway?

I don't think you can - CF has always uppercased the Keys.

My page would actually have this as the link http://someurlhere.com/disclaimer.cfm?destination= http://go.reuters.com/newsArticle.jhtml?type=healthNews&storyID=12037965&src=eDialog/GetContent The suspect the trouble is the second '?' character.  It should not be allowed.  The simplest solution, but untried, would be to urlencode() your destination value so that these special characters are escaped.  You can then urlDecode() the value in your redirection page to get the folks to where they are supposed to go. -------------- Ian Skinner Web Programmer BloodSource www.BloodSource.org Sacramento, CA --------- | 1 |   | ---------  Binary Soduko |   |   | --------- "C code.

Hi Tuan Maybe something like this would help, <cfset ourString = "Src=blahblah&storyID=1234&Yahoo=hello"> <cfloop list=#ourString# index="i" delimiters="&"> <cfset ourString2 = #i#> <cfoutput>#i#</cfoutput></br> <cfloop list=#ourString2# index="i2" delimiters="="> <cfoutput>#i2#</cfoutput></br> </cfloop> <hr> </br> </cfloop> This is only rough but im sure you get the jist, obviously you would need to pretty it up and the var set would be your query string instead, i mean there are numerous paths you could take, this was the route I initially thought of. Hope it helps Jose

Ok, this is what you want to do.  I ran this test code and I get all your second level url variables. <cfdump var="#url#"> <cfoutput> <a href="http:url.cfm?destination=#urlEncodedFormat('http://go.reuters.com/newsArticle.jhtml?type= healthNews&storyID=12037965&src=eDialog/GetContent')#">Test</a> </cfoutput> -------------- Ian Skinner Web Programmer BloodSource www.BloodSource.org Sacramento, CA --------- | 1 |   | ---------  Binary Soduko |   |   | --------- "C code.

The problem I have with this is I'm not the one putting these links on the page.  There are users who uses a content managment system that enters in the content for the website.  I want to avoid making the users use Coldfusion code b/c they don't understand it and it will complicate things for them.  I wanted to this in such a way that all the coldfusion code is on the disclaimer page (which I control) and the referring page (content page w/ the link) is just plain html that is written for them thru the content managment system they use.  Is there another way of doing this?  Thanks for your help though. jhtml> ?type=healthNews&storyID=12037965&src=eDialog/GetContent')#">Test</a>

How is the actual link built in your example?  I'm assuming this is built on some cfm page, if so you just need to wrap the first link in a urlEncodedFunction() when you make the second link. If this is not possible, you could treat the entire link as a list delimitated by the question mark ('?').  The first element of the list is your url, the second element would be your url parameters and the third element would be the url parameters of the second link.   Does that make sense? -------------- Ian Skinner Web Programmer BloodSource www.BloodSource.org Sacramento, CA --------- | 1 |   | ---------  Binary Soduko |   |   | --------- "C code.

The users simply uses the CMS tool and clicks on the "create hyperlink" button and copys and paste the link in the field.  The user never sees any html.

Yes, the user can view the source code which would take them out of WYSIWYG mode.  Then they would have to sniff thru all the HTML to find the link and wrap it w/ coldfusion code before they save the document.  This is precisely something I don't want them to do because they are not developers, just content editors with no web knowledge. Now instead of them wrapping the link w/ coldfusion code I could probably do it after they save the document.  But that would involve me opening up the database where the content is stored, finding the document and then the link and wrapping it myself.  The problem with this is the extra work for me and the need for the content editor to contact me whenever a link such as this exist. So I'm basically trying to find a way to have the disclaimer page extract the complete URL from the referring page (which is the page the content editor makes). Anybody got a solution?

Tuan, I'm not sure what you are trying to do, but here's a trick that allows you to manipulate links after the facts, as long as they are inside of "<a/> tags. Let's say your user put in "<a href="http://blah.com?name=joe J. Smith">Joe J. Smith</a>. What you want to appear is actually <a href="http://blah.cfm?nameJoe%20J%2E%20Smith">Joe J. Smith</a> But you do not want the user to encode it him or herself and you do not what to allow them to do something like "#urlencodedformat("joe j. smith")#" Here's a simple way to do that. On the page that is being served (presumably a CFM Page). Add the following: <cfimport taglib="htm" prefix=""/> Then, create a folder called "htm" that branches from that same directory (where the page is being served).  Inside that folder place a file titled "a.cfm" that can rewrite it for you.  The result is that CF treats a call to <a> as if it were a call to the custom tags. The interior attributes become attributes of the tag.  You could even enforce a URL handler to track clicks or whatever. You could do the same with the "<form> tag, <div> tag.. Whatever.... I have a good sample on my blog: http://mkruger.cfwebtools.com/index.cfm/2006/5/10/adaptive.tags

That is def v cool mark, I had never even thought of doing that :-) Tuan, I'm not sure what you are trying to do, but here's a trick that allows you to manipulate links after the facts, as long as they are inside of "<a/> tags.

So I'm basically trying to find a way to have the disclaimer page extract the complete URL from the referring page (which is the page the content editor makes). Do you have this disclaimer page?  Or are you asking how to substitute a disclaimer page when a user clicks on a link in content made by your CMS? I understood from your first post, that you had the disclaimer page working, but that when users clicked on the link in it, the did not get to some pages properly if the relocation link had url parameters.  Is this correct?  Do you have a page that makes these links for you? http://someurlhere.com/disclaimer.cfm?destination=http://go.reuters.com/newsArticle.jhtml?type= healthNews&storyID=12037965&src=eDialog/GetContent Or are you asking for help on how to create these kinds of links in the first place. -------------- Ian Skinner Web Programmer BloodSource www.BloodSource.org Sacramento, CA --------- | 1 |   | ---------  Binary Soduko |   |   | --------- "C code.

I do already have a disclaimer page.  Lets say I have a page called content.cfm and a page called disclaimer.cfm.  The user will use a CMS tool to write the content for the content.cfm page.  They have no control over the layout of the page (headers, navigation, footers, or anything like that).   Using this tool, the user creates the content and creates any links.  The user does NOT see any HTML at all.  The CMS tool does everything for the user. Now when a user creates a link in content.cfm they prefix any link with http://mysitename. com/disclaimer.cfm?destination= For example a link a user might enter into the CMS tool might look like: http://mysitename.com/disclaimer.cfm?destination=http://someurlhere.com/disclaimer.cfm?destination= http://go.reuters.com/newsArticle.jhtml?type=healthNews&storyID=12037965&src=eDialog/GetContent So the disclaimer page is displayed first before redirecting the user to the intended link. What my disclaimer.cfm page does now is extracts the value from the destination url variable and a javascript then redirects the page to that value.  But it doesn't work when there are multiple URL parameters in the destination URL, like in the Reuter link above. I'm trying to find a solution that would allow the disclaimer.cfm page to do all the work of extracting and creating the redirect link correctly without having the user do anything different on the content.cfm page. I hope this clears up my problem.  I really don't know how else to explain it.

You can replace url's on the fly, or resave it to the database with the following... You can also put a <cfloop> around the whole thing and do it for every record in the database <!--- GET ALL PAGES WITH BAD URLS FROM DATABASE ---> <CFQUERY Name="SetURL" datasource="#Application.Datasource#"> SELECT PageDataField FROM tbl_gallery WHERE ID = <cfqueryparam cfsqltype="cf_sql_integer" value="1" maxlength="4"> </CFQUERY> <!--- OK - SET THE NEW URLs WHERE NEEDED---> <CFSET newPageContent = #ReplaceNoCase(SetURL.PageDataField,"<a href=""http://" , "<a href=""http://phat-links.com/page.cfm?goto=","ALL")#>; <!--- UPDATE DATABASE RECORD TO REFERENCE NEW URL ---> <cfoutput> #newPageContent# </cfoutput>

Now that is rather interesting.  I can see some use for that behavior. -------------- Ian Skinner Web Programmer BloodSource www.BloodSource.org Sacramento, CA --------- | 1 |   | ---------  Binary Soduko |   |   | --------- "C code.
