插入由主键链接的表

我有两张关系表

+----------------------+      +-----------------+
|        Shape         |      |  Point_Values   |
+----------------------+      +-----------------+
| shape_id (KEY)       |      | id (KEY)        |
| shape_name (VARCHAR) |      | point_x (INT)   |
+----------------------+      | point_y (INT)   |
                              | shape_id (INT)  |
                              +-----------------+

如何在同一个请求中获得形状和点的同时，如何构建一般的插入或CodeIgniter，这意味着当一个形状完成时，有一个点数组和形状名称/ id。我必须在表中插入，但两者都匹配shape_id。 按要求 排列 （     [name] =>“circle”     [points] =>数组         （             [x] =>数组                 （                     [0] => 182                     [1] => 190                     [2] => 215                     [3] => 240                     [4] => 291                     [5] => 328                     [6] => 364                     [7] => 391                     [8] => 425                     [9] => 459                     [10] => 487                     [11] => 512                     [12] => 529                     [13] => 540                     [14] => 551                     [15] => 560                     [16] => 570                     [17] => 581                     [18] => 592                     [19] => 604                     [20] => 617                     [21] => 628                     [22] => 635                     [23] => 639                     [24] => 642                     [25] => 642                     [26] => 640                     [27] => 630                     [28] => 619                     [29] => 606                     [30] => 591                 ）             [y] =>数组                 （                     [0] => 165                     [1] => 159                     [2] => 150                     [3] => 147                     [4] => 144                     [5] => 144                     [6] => 147                     [7] => 152                     [8] => 162                     [9] => 172                     [10] => 184                     [11] => 199                     [12] => 211                     [13] => 219                     [14] => 225                     [15] => 228                     [16] => 231                     [17] => 232                     [18] => 233                     [19] => 233                     [20] => 231                     [21] => 222                     [22] => 204                     [23] => 189                     [24] => 156                     [25] => 133                     [26] => 120                     [27] => 100                     [28] => 85                     [29] => 69                     [30] => 54                 ）         ） ）
