I've created a keyword's property type using the textbox multiple data type.

The keywords are then seperated into a list of words or phrases seperated by commas.

I've wrapped the keywords in A tag with the href linking to my search page, and including the value of the keyword so that all nodes with the same keyword will display in my search.

I want to add an option where a user can select from checkboxes with the value of the keyword, and submit a search so all checked keywords are included in the search.

I need help with figuring out how to get the checked values of the list of keyword checkboxes to submit and display the results on my seach page.

Here is what I have so far, which doesn't submit and I can't find where to add the values of the checkboxes:

<xsl:if test="string($currentPage/keywords) != ''">

<!-- get the contents of the textbox multiple, with commas -->
<xsl:variable name="textWithBrs" select="umbraco.library:ReplaceLineBreaks($currentPage/keywords)"/>

<!-- replace commas with pipes so you can use Split -->
<xsl:variable name="textWithPipes" select='umbraco.library:Replace($textWithBrs, ", ", "|")'/>

<!-- split into an array of items and output as unordered list -->
<xsl:variable name="items" select="umbraco.library:Split($textWithPipes, '|')"/>
<ul>
  <xsl:for-each select="$items/value">
    <li>
      <input type="checkbox" value="true" keyword="{.}" id="{.}" name=""/>
      <a>
      <xsl:attribute name="href"> <xsl:text disable-output-escaping="yes">/imagery/image-search.aspx
      <![CDATA[?]]>
      search=</xsl:text> <xsl:value-of select="." /> </xsl:attribute>
      <xsl:attribute name="title"> <xsl:value-of select="."/> </xsl:attribute>
      <xsl:value-of select="."/> </a> </li>
  </xsl:for-each>
</ul>
<input type="submit" value="Search" id="btnSearchBottom" name="" onclick="location.href='/imagery/image-search.aspx?search=otbra'" />
</xsl:if>

Any assistance would be greatly appreciated.

Cheers, JV
