Sometimes I want to put checkboxes in columns, so I changed the html_checkboxes function to be able to do that.

You indicate the number of columns "num_columns" and the "column_separator" to be used instead of the "separator" when there is a column break. For example, inside of a table I use it like this:

Code:

         <tr>
            <td style="width:50%">
               <ul style="list-style:none; margin:0; padding:0;">
                  <li>
                     <{html_checkboxes name="`$form_id`[institutions]" options=$institutions
                          separator='</li><li>' labels=true num_columns=2 column_separator='</li></ul></td><td  style="width:50%"><ul style="list-style:none; margin:0; padding:0;"><li>' }>
                  </li>
               </ul>
            </td>
         </tr>




One other change is that I made it so it doesn't output a separator after the last checkbox, as there is no other item to "separate" it from. It works in smarty 2, haven't tested in smarty 3.

Code:

/**
 * Smarty {html_checkboxes} function plugin
 *
 * File:       function.html_checkboxes.php<br>

 * Date:       24.Feb.2003<br>
 * Purpose:    Prints out a list of checkbox input types<br>
 * Input:<br>

 *           - output     (optional) - the output next to each checkbox
 *           - assign     (optional) - assign the output as an array to this variable
 *           - num_columns     (optional) - used w/column_separator, how many columns
 *           - column_separator     (optional) - the separator to use between columns instead of "separator" param
 * Examples:
 * <pre>
 * {html_checkboxes values=$ids output=$names}
