1.修改includes/lib_goods.php，改写下两个函数。

  2. /**
  3. * 获得指定分类同级的所有分类以及该分类下的子分类
  4. *
  5. * @accesspublic
  6. * @paraminteger$cat_id分类编号
  7. * @returnarray
  8. */
  9. function get_categories_tree($cat_id = 0)
  10. {
  11. if ($cat_id > 0)
  12. {
  13. $sql = 'SELECT parent_id FROM ' . $GLOBALS['ecs']->table('category') . " WHERE cat_id = '$cat_id'";
  14. $parent_id = $GLOBALS['db']->getOne($sql);
  15. }
  16. else
  17. {
  18. $parent_id = 0;
  19. }
  20. /*
  21. 判断当前分类中全是是否是底级分类，
  22. 如果是取出底级分类上级分类，
  23. 如果不是取当前分类及其下的子分类
  24. */
  25. $sql = 'SELECT count(*) FROM ' . $GLOBALS['ecs']->table('category') . " WHERE parent_id = '$parent_id' AND is_show = 1 ";
  26. if ($GLOBALS['db']->getOne($sql) || $parent_id == 0)
  27. {
  28. /* 获取当前分类及其子分类 */
  29. $sql = 'SELECT cat_id,cat_name ,parent_id,is_show ' .
  30. 'FROM ' . $GLOBALS['ecs']->table('category') .
  31. "WHERE parent_id = '$parent_id' AND is_show = 1 ORDER BY sort_order ASC, cat_id ASC";
  32. $res = $GLOBALS['db']->getAll($sql);

  34. $sql = "SELECT cat_id, COUNT(*) AS goods_num " .
  35. " FROM " . $GLOBALS['ecs']->table('goods') . " AS g " .
  36. " GROUP BY cat_id";

  38. $res2 = $GLOBALS['db']->getAll($sql);
  39. $newres = array();
  40. foreach($res2 AS $row)
  41. {
  42. $newres[$row['cat_id']] = $row['goods_num'];
  43. }

  45. foreach ($res AS $row)
  46. {
  47. if ($row['is_show'])
  48. {
  49. $cat_arr[$row['cat_id']]['id']= $row['cat_id'];
  50. $cat_arr[$row['cat_id']]['num']= !empty($newres[$row['cat_id']]) ? $newres[$row['cat_id']] : 0;
  51. $cat_arr[$row['cat_id']]['name'] = $row['cat_name'];
  52. $cat_arr[$row['cat_id']]['url']= build_uri('category', array('cid' => $row['cat_id']), $row['cat_name']);
  53. if (isset($row['cat_id']) != NULL)
  54. {
  55. $cat_arr[$row['cat_id']]['cat_id'] = get_child_tree($row['cat_id']);
  56. }
  57. }
  58. }
  59. }
  60. if(isset($cat_arr))
  61. {
  62. return $cat_arr;
  63. }
  64. }
  65. function get_child_tree($tree_id = 0)
  66. {
  67. $three_arr = array();
  68. $sql = 'SELECT count(*) FROM ' . $GLOBALS['ecs']->table('category') . " WHERE parent_id = '$tree_id' AND is_show = 1 ";
  69. if ($GLOBALS['db']->getOne($sql) || $tree_id == 0)
  70. {
  71. $child_sql = 'SELECT cat_id, cat_name, parent_id, is_show ' .
  72. 'FROM ' . $GLOBALS['ecs']->table('category') .
  73. "WHERE parent_id = '$tree_id' AND is_show = 1 ORDER BY sort_order ASC, cat_id ASC";
  74. $res = $GLOBALS['db']->getAll($child_sql);


  77. $sql = "SELECT cat_id, COUNT(*) AS goods_num " .
  78. " FROM " . $GLOBALS['ecs']->table('goods') . " AS g " .
  79. " GROUP BY cat_id";
  80. $res2 = $GLOBALS['db']->getAll($sql);
  81. $newres = array();
  82. foreach($res2 AS $row)
  83. {
  84. $newres[$row['cat_id']] = $row['goods_num'];
  85. }

  87. foreach ($res AS $row)
  88. {
  89. if ($row['is_show'])
  90. $three_arr[$row['cat_id']]['num']= !empty($newres[$row['cat_id']]) ? $newres[$row['cat_id']] : 0;
  91. $three_arr[$row['cat_id']]['id']= $row['cat_id'];
  92. $three_arr[$row['cat_id']]['name'] = $row['cat_name'];
  93. $three_arr[$row['cat_id']]['url']= build_uri('category', array('cid' => $row['cat_id']), $row['cat_name']);
  94. if (isset($row['cat_id']) != NULL)
  95. {
  96. $three_arr[$row['cat_id']]['cat_id'] = get_child_tree($row['cat_id']);
  97. }
  98. }
  99. }
  100. return $three_arr;
  101. }

2.修改category_tree.lib库，写入num变量。
  1. <meta http-equiv="Content-Type" content="text/html; charset=gbk">
  2. <div class="box">
  3. <div class="box_1">
  4. <div id="category_tree">
  5. <!--{foreach from=$categories item=cat}-->
  6. <dl>
  7. <dt><a href="{$cat.url}">{$cat.name|escape:html}</a>({$cat.num})</dt>
  8. <!--{foreach from=$cat.cat_id item=child}-->
  9. <dd><a href="{$child.url}">{$child.name|escape:html}</a>({$child.num})</dd>
  10. <!--{foreach from=$child.cat_id item=childer}-->
  11. <dd><a href="{$childer.url}">{$childer.name|escape:html}</a>({$childer.num})</dd>
  12. <!--{/foreach}-->
  13. <!--{/foreach}-->

  15. </dl>
  16. <!--{/foreach}-->
  17. </div>
  18. </div>
  19. </div>
  20. <div class="blank5"></div>
