Is this the right way to do

Hello,

For my website I'm looking for a xslt pagination script to use with Symphony cms.
Now I found this one : http://www.codeproject.com/KB/dotnet/pagination.aspx

But one thing looks wierd to me.
Here's the code:

Code:

 <xsl:for-each select="root/customer">
       <!-- Pagination logic -->
       <xsl:if test="position() &gt;= ($Page * $PageSize) + 1">
        <xsl:if test="position() &lt;= $PageSize + ($PageSize * $Page)">


         <!-- Do display here -->
         
        </xsl:if>
       </xsl:if>
      </xsl:for-each>

When Im on page 1 ($Page=1) and I would display 1 article (pagesize=1)
Then the first xsl is false because position = 1 and page*pagesize =1 + 1 = 2

So in my opion it never reach the <!-- do display here
But how can I take care that there will be something to display.

At the start of that article it states:

Quote:

Note: First page id is 0

So when you are the first page, $Page will equal 0 and position() will equal 1 for the item you want to display.

Oke
But I don't agree complete with you.
It is correct that position will be 1.
$page = 0 .

So 1 > (0*1)+1 so 1 > 0 + 1 so 1 > 1 and that not right so the next if will never be reached in my opionon.

It is ">=" and not just ">".

Thanks,

Wierd that you then write >= and not simple >= .

Not when ">" is invalid inside an attribute value in XML its not. Actually ">" might be valid but "<" isn't, so they are just being consistent.

Thanks, I learned another thing about xslt.

I have another question and I don't know if I can ask here of make another topic.

I have the variable itemsPerPage. I want to change the value. I have read that I cannot change a value of a variable. So I think I need a parameter.

Am I on the right track that I can change the value of a parameter ?
And is there a example how to do that.

parameters are just variables that are set by the XSLT processor and can be passed in at runtime. They cannot be altered either.

Start a new topic and tell us what you are trying to accomplish and we will try to help.
