PHP版表格展示无限级分类
TreeTable是一个能把无限分类展现为表格形式的PHP类库插件,分类的层级表示为表格的列,分类的行数表格分类的总数,单元格显示分类名称.
TreeTable通过对单元格的行合并和列合并实现了无限层级也能较好的展示层级架构.
1.构建ID/PID/NAME的数组,后期可通过数据库生成的动态数据,代码如下:
- array(
- * 1 => array('id'=>'1','parentid'=>0,'name'=>'一级栏目一'),
- * 2 => array('id'=>'2','parentid'=>0,'name'=>'一级栏目二'),
- * 3 => array('id'=>'3','parentid'=>1,'name'=>'二级栏目一'),
- * 4 => array('id'=>'4','parentid'=>1,'name'=>'二级栏目二'),
- * 5 => array('id'=>'5','parentid'=>2,'name'=>'二级栏目三'),
- * 6 => array('id'=>'6','parentid'=>3,'name'=>'三级栏目一'),
- * 7 => array('id'=>'7','parentid'=>3,'name'=>'三级栏目二')
- * )
2.导入TreeTable类库,代码如下:
- import('@.ORG.Util.TableTree');
- $treeTable->init($treearr);
- echo $treeTable->get_treetable();
注意:get_treetable()只生产表体部门,<TALBE></TABLE>请自行构建.
