function tablefield_field in TableField 6

Implementation of hook_field().

File

./tablefield.module, line 89

This module provides a set of fields that can be used to store tabular data with a node. The implementation uses a custom CCK widget.

Code

function tablefield_field($op, &$node, $field, &$items, $teaser, $page) {
  switch ($op) {
    case 'presave':
