Pass a URL as a variable in the URL

Hi SiriusPhil,

What do you mean? Like:

http://www.example.com/url.php?url=http://someotherexample.com/

? Yes, that's possible and you would get it out of the URL just like any other GET variable. I have no idea about ColdFusion syntax but it would be like that. Just make sure to URLEncode the URL first.

yeah it's possible

Like this

startpage.cfm
----------------------

<cfset MyVarr = "Http://www.yourdomain.cfm">

<form name="myform" action="actionpage.cfm?VariableOne=#MyVarr#" method="post">

...form elements...

...submit button....

</form>

actionpage.cfm
------------------------------------------
<cfparam name="url.VariableOne" default="">

<cfoutput>

My URL Variable: #Url.VariableOne#<br>

<a href="#Url.VariableOne#"> Here's the link</a>

</cfoutput>

URLEncodedFormat(string [, charset ])

oops forgot to account for the URLEncodedFormat

here:

startpage.cfm
----------------------

<cfset MyVarr = "http://www.yourdomain.cfm">

<form name="myform" action="actionpage.cfm?VariableOne=#URLEncodedFormat(MyVarr)#" method="post">

...form elements...

...submit button....

</form>

actionpage.cfm
------------------------------------------
<cfparam name="URL.VariableOne" default="">
<cfset MyVarr = URLDecode(URL.VariableOne)>

<cfoutput>

My URL Variable: #MyVarr#<br>

<a href="#MyVarr#"> Here's the link</a>

</cfoutput>

Woops..

Forgot to tell you one thing...

Some of the URL's I want to send as variables have variables in them too.

Can I send somethong like...

http://foo.com?id=1

through a URL variable?

here:

startpage.cfm
----------------------
<cfset next = SomethingElse">
<cfset mysecond = "Something">
<cfset MyVarr = "http://www.yourdomain.cfm?mySecond=#SecondVarr#&next=#next#">

<cfset extra = "AdditionalVariables">

<form name="myform" action="actionpage.cfm?MyURL=#URLEncodedFormat(MyVarr)#&extra=#extra#" method="post">

...form elements...

...submit button....

</form>

actionpage.cfm
------------------------------------------
<cfparam name="URL.MyURL" default="">
<cfset MyVarr = URLDecode(URL.MyURL)>

<cfparam name="URL.extra" default="">
<cfset extra = URL.extra>

<cfoutput>

My URL Variable: #MyVarr#<br>
My Extra Variables: #extra#<br>

<a href="#MyVarr#"> Here's the link</a>

</cfoutput>

yeah good catch mrichmon, pass any additional url variables before the passedURL

also you make a good point about accessing variables in the passed url.

between the two posts that should cover what you are looking to do ;o)
