Question

Replace select box with images in form

Asked by: panosms

Hello experts.
I use a form to change the language in my site.
I want now to replace the select box with images.
I have a form with images so you can make the changes and also i have a solution where i use for each flag one form but i don't know if this is the right way.
Please don't use URL values.

<form action="#CGI.SCRIPT_NAME#" method="post" enctype="multipart/form-data" name="LanguageForm" id="LanguageForm">
    <select name="lang" onChange="document.LanguageForm.submit();">
      <option <cfif cookie.lang EQ "de" >selected="selected"</cfif> value="de" >Deutsch</option>
      <option <cfif cookie.lang EQ "eng" >selected="selected"</cfif> value="eng" >Englisch</option>
      <option <cfif cookie.lang EQ "gr" >selected="selected"</cfif> value="gr" >Griechisch</option>
    </select>
    </form>
 
 
Form with images:
<form action="#CGI.SCRIPT_NAME#" method="get" enctype="multipart/form-data" name="LanguageForm" id="LanguageForm">
     <input name="lang" type="image" value="de" src="../img/FLAGS/Germany.svg.png" />
     <input name="lang" type="image" value="eng" src="../img/FLAGS/United_Kingdom.svg.png"/>
     <input name="lang" type="image" value="gr" src="../img/FLAGS/Greece.svg.png" />
    </form>
 
my solution:
<TABLE border="0" align="right" cellpadding="2" cellspacing="0"><TR>
    <TD><form action="" method="POST" enctype="multipart/form-data" name="LanguageForm" id="LanguageForm">
     <input name="lang" title="Deutsch" type="image" value="de" src="../img/FLAGS/Germany.svg.png" onclick="document.LanguageForm.submit();" /></form></TD>
    <TD><form action="" method="POST" enctype="multipart/form-data" name="LanguageForm" id="LanguageForm">
     <input name="lang" title="Englisch" type="image" value="eng" src="../img/FLAGS/United_Kingdom.svg.png" onclick="document.LanguageForm.submit();" /></form></TD>
    <TD><form action="" method="POST" enctype="multipart/form-data" name="LanguageForm" id="LanguageForm">
     <input name="lang" title="Griechisch" type="image" value="gr" src="../img/FLAGS/Greece.svg.png" onclick="document.LanguageForm.submit();" />
    </form></TD></TR></TABLE>

When you submit using an image, the value passed will be the x/y coordinates of where you clicked.  The value attribute is ignored.  So for instance this:
<input name="lang" type="image" value="de" src="../img/FLAGS/Germany.svg.png" />
will be available on the processing page as
Form.lang.x
Form.lang.y

So by having three buttons with the same name, you won't be able to tell them apart.  Instead I suggest you try the following.

PS: you only need enctype="multipart/form-data" if you're submitting a file in the form.  

<form action="#CGI.SCRIPT_NAME#" method="get" enctype="multipart/form-data" name="LanguageForm" id="LanguageForm">
     <input name="de" type="image" src="../img/FLAGS/Germany.svg.png" />
     <input name="eng" type="image" src="../img/FLAGS/United_Kingdom.svg.png"/>
     <input name="gr" type="image" src="../img/FLAGS/Greece.svg.png" />
    </form>
 
 
<!--- processing --->
<cfif IsDefined("form.de.x")>
<!--- DE --->
 
<cfelseif IsDefined("form.eng.x")>
<!--- ENG --->
 
<cfelseif IsDefined("form.gr.x")>
<!--- GR --->
 
</cfif>

Hi
This is the form:
<form action="#CGI.SCRIPT_NAME#" method="get" enctype="multipart/form-data" name="LanguageForm" id="LanguageForm">
     <input name="de" type="image" src="../img/FLAGS/Germany.svg.png" />
     <input name="eng" type="image" src="../img/FLAGS/United_Kingdom.svg.png"/>
     <input name="gr" type="image" src="../img/FLAGS/Greece.svg.png" />
    </form>
And in the application.cfm i have this:
<cfparam name="cookie.lang" default="de">
<cfif IsDefined("form.de.x") AND form.de.x NEQ cookie.lang >
<!--- DE --->
 
  <cfcookie name="lang" value="de" expires="never">
 
<cfelseif IsDefined("form.eng.x") AND form.eng.x NEQ cookie.lang>
<!--- ENG --->
 <cfcookie name="lang" value="eng" expires="never">
<cfelseif IsDefined("form.gr.x") AND form.gr.x NEQ cookie.lang>
<!--- GR --->
 <cfcookie name="lang" value="gr" expires="never">
</cfif>

This is not working.
By the way the solution with the three forms is working.Is this wrong?
Is it better to use url variable?

what's the deal with the cookie.lang?  

the value of x and y will be numeric, think of it as coordinates for where you click on the image.  the value will never equal the value of your cookie, as you're setting the cookie to be a string.

also, why is your code in application.cfm?  that's the wrong place to put this sort of stuff, put it in the same page as the form, as you seem to be submitting the form back to the current page.

Hi again.
Using the form i set a cookie with the language the client prefer.
So every time he is on the site he will have the language he wants .
I have put this in the application because i did not want to write the code in all pages or templates.
Where is the right place to put this?
I understand what you mean with x and y but i still did not get it work.
Submitting the form i have this in URL:
testpage.cfm?de.x=10&de.y=10#CGI.SCRIPT_NAME#
What must be te cfif tag to get it work?
This is not working.(it is on the page i submit)
<cfif IsDefined("form.de.x")>
<!--- DE --->
 
  <cfcookie name="lang" value="de" expires="never">
  <cfset vlangid = de>
<cfelseif IsDefined("form.eng.x")>
<!--- ENG --->
 <cfcookie name="lang" value="eng" expires="never">
 <cfset vlangid = eng>
<cfelseif IsDefined("form.gr.x")>
<!--- GR --->
 <cfcookie name="lang" value="gr" expires="never">
 <cfset vlangid = gr>
</cfif>

Firstly, if your URL actually says testpage.cfm?de.x=10&de.y=10#CGI.SCRIPT_NAME#  then there's a problem.  You've got a variable there that you should have put cfoutput around for it to work.  i.e. wrap a <cfoutput></cfoutput> around your whole form.  

Secondly, the reason your code isn't working is because you're checking for FORM.de.x, FORM.eng.x etc.  But you've just identified that the values are being passed in the URL.  Change your code to:

<cfif IsDefined("url.de.x")>
<!--- DE --->
 
  <cfcookie name="lang" value="de" expires="never">
  <cfset vlangid = de>
<cfelseif IsDefined("url.eng.x")>
<!--- ENG --->
 <cfcookie name="lang" value="eng" expires="never">
 <cfset vlangid = eng>
<cfelseif IsDefined("url.gr.x")>
<!--- GR --->
 <cfcookie name="lang" value="gr" expires="never">
 <cfset vlangid = gr>
</cfif>
