Re: disabling widgets in CForms

A while ago I created an extra template in my woody (cforms) to show/not show a group of widgets if a checkbox is clicked. It may give you something to begin with:

This template goes in your woody/cform stylesheet or create your own stylesheet and let this stylesheet include the other woody/cform stylesheets

<xsl:template match="wi:group[wi:styling/@type='checkboxGroup']">

     <xsl:variable name="value" select="wi:state/wi:*/wi:value"/>


    <xsl:variable name="state-widget" select="wi:state/wi:*/@id"/>

    <xsl:variable name="id" select="generate-id()"/>
        <xsl:apply-templates select="wi:label/node()"/>
  <xsl:apply-templates select="text()"/>
        <input type="checkbox" name="{$state-widget}" >
   <xsl:if test="$value = 'true'">
    <xsl:attribute name="checked">true</xsl:attribute>
   </xsl:if>
  </input>
        <xsl:if test="wi:items/*//wi:validation-message">
          <span style="color:red; font-weight: bold"> ! </span>
        </xsl:if>

<xsl:for-each select="wi:items/wi:*">
        <div id="{$id}_items_{position() - 1}">
   <xsl:if test="not($value = @displayWhen)">
    <xsl:attribute name="style">display:none</xsl:attribute>
   </xsl:if>
          <xsl:apply-templates select="."/>
        </div>
      </xsl:for-each>
</xsl:template>

Use this to show the checkbox (template):

<wi:group>
    <wi:styling type="checkboxGroup"/>
    <wt:widget-label id="state"/>
    <wi:state>
      <wt:widget-label id="state"/>: <wt:widget id="state"/>
    </wi:state>
    <wi:items>
       <wi:group displayWhen="false">
        <wi:items>
         Name:  <wt:widget id="name"/>
        </wi:items>
       </wi:group>
   </wi:items>
</wi:group>

definition:

  <wd:booleanfield id="state">
   <wd:label>Do you want to give your name?</wd:label>
  </wd:booleanfield>
  <wd:field id="name">
   <wd:datatype base="string"/>
  </wd:field>

This should give you a textbox asking if you want to give your name, if checked a textfield should appear.

Note however, that this is just one way, you may accomplish the same by using _javascript_!

Kind Regards,

Jan

Subject: disabling widgets in CForms

Hi,

Is there a way to disable groups of widgets in CForms?

My application:

Payment:

(x) Invoice

( ) Credit Card

CC Number

CC Expiry

There is a choice between invoice or CC payment. In case the user

selects Invoice payment the CC Number and CC expiry field should

not get validated and at best not even be displayed.

Is there any preferred way to do this in CForms?

thanks for any suggestions.
