Multiple

Templating System : Designer Guide : Tag Reference : Multiple

Summary

The multiple tag is used to repeat a template section for each row of a multirow data source. Column variables are reset with each repetition to the values of the next row of the data source.

Usage

<!-- Begin multiple layout, i.e. <table> -->
<table>

<multiple name="users">

  <!-- Row layout, i.e. <tr>...</tr> -->
  <tr>

    <td>
     @users.first_name@
    </td>

    <td>
      @users.last_name@
    </td>

    <td>
      @users.state@
    </td>

  </tr>

</multiple>

<!-- End multiple layout, i.e. </table> -->
</table>

Notes

• The special variable datasource:rowcount may be used to check for no rows in a data source (or any other special condition related to the number of rows in the data source).

• The special column datasource.rownum is set implicitly for each repetition and can be used in conjunction with the if tag to do row banding:

    <multiple>
  
    <if @datasource.rownum@ odd>
      <tr bgcolor="#eeeeee">
    </if>
  
    <if @datasource.rownum@ even>
      <tr bgcolor="#ffffff">
    </if>
  
    ...
  

• The maxrows attribute may be used to limit the number of rows that are output from the data source:

    <multiple maxrows="n">
    ...
  

  This attribute will cause processing to stop after n rows have been output.

• The startrow attribute may be used to skip a number of rows at the beginning of the data source:

    <multiple startrow="n">
    ...
  

  This attribute will cause processing of the data source to begin at row n + 1.

• [Note: Carsten added this feature during the Berlin Hackaton 2004-02-14]

  The delimiter attribute will add a string after each row except the last row:

    <multiple delimiter=" | ">
    ...
  

  This attribute will cause the rows to appear to be sepparated by vertical bars. This is much more convenient than using the <if> tags to check whether we are on the last row.

• The startrow and maxrows attributes may be used together to output any range from the data source.

• See the group tag for formatting subsets of a multirow data source. In the current implementation, the <multiple> tag does not nest.
