Passing an identifier using hyperlink

Report · Oct 01, 2009

Hello;

I am at a loss. I fogot how to be able to pass a simple peramiter using a hyper link back to it's self on the same page. I also need the code that it activates only to activate if the link is used. How do I do this using a hyper link? I know how to use forms like this.

This is how the link works if I use another page to activate the code:

applysetting.cfm

index.cfm

<a href="apply-setting.cfm?engage=hitbox">Sound On</a>

or

<a href="apply-setting.cfm?deactivate=hitbox">Sound Off</a>

I am trying to make it work on one page:

index.cfm

<head>

</head>

<body>

<a href="index.cfm?engage=hitbox">Sound On</a>

or

<a href="index.cfm?deactivate=hitbox">Sound Off</a>

</body>

as it sits right now, it doesn't work properly.How can I adjust this so I can just make it load the one page and not the applysetting.cfm to make it work?

Thank you

Look at the address bar of your browser for an example.

So how owuld I write my if statement for activating the code using this? index.cfm?deactivate=hitbox that was copied from my url. It seems to fire to turn off my app, but not to turn it on.

Something very similar was discussed here:

I re-wrote the code similar to the link you posted. I still can't get this to go off properly. I believe I have this coded wrong.

Can anyone help me fix this so it will work properly?This is what I changed the code to:

</cfswitch>

<head>

</head>

<body>

<a href="index.cfm?engage=hitbox">Sound On</a>

<cfelse>
<a href="index.cfm?deactivate=hitbox">Sound Off</a>

</cfif>

</body>

Does anyone have any ideas?
Thank you

I think you are trying something like this:

<cfparam name="url.hitbox" default="" />
<cfswitch expression="#url.hitbox#">
    <cfcase value="deactivate">
        <cfcookie name="hibox" value="Off" expires="never">
    </cfcase>
    <cfcase value="engage">
        <cfcookie name="hitbox" value="On" expires="now">
        <cfset structDelete(cookie,'hitbox') />
    </cfcase>
</cfswitch>
<cfif IsDefined("cookie.hitbox")>
    <a href="index.cfm?hitbox=engage">Sound On</a>
<cfelse>
    <a href="index.cfm?hitbox=deactivate"><strong><u>Sound Off</u></strong></a>
</cfif>

cool! It now turns off the music, but for some reason it is not turing it back on. I'll show you:

</cfswitch>

this is the link that doesn't work. Am I setting my cookie wrong?

<a href="index.cfm??hitbox=engage">Sound On</a>

working link

</cfif>

Can't figure out what I am doing wrong. I set a cookie that expires and then delete it. I'm confused

How about just checking the value of the cookie?

<cfparam name="url.hitbox" default="" />
<cfparam name="cookie.hitbox" default="" />
<cfswitch expression="#url.hitbox#">
    <cfcase value="deactivate">
        <cfcookie name="hitbox" value="Off" expires="never">
    </cfcase>
    <cfcase value="engage">
        <cfcookie name="hitbox" value="On" expires="never">
    </cfcase>
    <cfdefaultcase>
        <cfcookie name="hitbox" value="Off" expires="never">
    </cfdefaultcase>
</cfswitch>
<cfif cookie.hitbox EQ "Off">
    <a href="index.cfm?hitbox=engage">Sound On</a>
<cfelse>
    <a href="index.cfm?hitbox=deactivate"><strong><u>Sound Off</u></strong></a>
</cfif>
