how can I use dynamic GET variables?

Hi CF people,

I created the following GET String with Javascript:

Code:

---

verarbeite.cfm?anzahl=5&id_3=12&menge_3=25&id_5=2&menge_5=100

---

this is how I did it:

Code:

---

Pseudocode:
var sendStr='?anzahl='+anzahl;
for(i=1 to anzahl)
{
  if(mengeID>0){
    sendStr=sendStr+'&id_'+i+'='+ID+'&menge_'+i+'='+mengeID;
  }
}
req4.open('get', 'verarbeite.cfm'+sendStr);

---

now I want to access with my "verarbeite.cfm" the single menge variables

Code:

---

<cfif IsDefined("anzahl")>
       
        <cfloop
          index = "loopCount"
          from = "1"
          to = #anzahl#
          step = "1">
               
                #menge_&loopCount# 
        </cfloop>
</cfif>

---

but how can I call menge_3, menge_5???
how do I get the connection beetween menge_ and loopCount??

Thanks

URL parameters can be accessed with url.[whatever]

Code:

---

<cfif isDefined("url.anzahl")>
  <cfset local.anzahl = url.anzahl>
</cfif>

If you want to set local variables for ALL URL parameters, make sure your parameter values are URLEncoded (escaped):

Code:

---

<cfif len(trim(cgi.query_string)) gt 0>
  <cfloop index="idx" list="#cgi.query_string#" delimiters="&">
        <cfset local.thisName = getToken(idx,1,"=")>
        <cfset local.thisValue = URLDecode(getToken(idx,2,"="))>
        <cfset "local.#local.thisName#" = trim(local.thisValue)>
  </cfloop>
  <cfdump var="#local#">
</cfif>

Untested, but it should work.

sorry for my late answer, but it works perfect. thanks!
