Passing variables with cfhttp

Dec 28, 2013 7:50 AM

Tags: #cfhttp

I need to pass a dynamic variable using cfhttp. 

 

This code:

 

<cfhttp method="get" url="#cgi.server_name#/page.cfm?pageid=#pageid#" resolveurl="Yes">

<cfoutput>

    #cfhttp.FileContent#

</cfoutput>

 

Returns the error:

 

The 3 parameter of the Mid function, which is now -8, must be a non-negative integer.

 

This code returns the same error.

 

<cfhttp method="post" url="#cgi.server_name#/page.cfm" resolveurl="Yes">

    <cfhttpparam type="Formfield"

        value="#pageid#"

        name="pageid">

</CFHTTP>

<cfoutput>

    #cfhttp.FileContent#

</cfoutput>

 

Any assistance would be appreciated.

    You don't say what line in your code is throwing the error...???  Try putting a

         <CFDUMP var="#cgi#">

    before the first line and a

         <CFDUMP var="#cfhttp#">

    after the CFHTTP call.  That will help you to understand if there is something wrong with the CGI var you are trying to pass as part of the URL, and will also show you whether the CFHTTP gets executed and what the return status is. Let us know how that works out and we can help you with further debugging.

     

    good luck!

    Search for the function mid() in the current page or in page.cfm. The error message is clear enough. The third argument of the method is currently -8, whereas it has to be a positive integer.
