我正在使用Codeigniter來查詢我的數據庫並返回數據數組。從數據數組創建一個Optgroup
我有一組數據,像這樣:
Array
(
[0] => stdClass Object
(
[depot_id] => 1
[depot_name] => Stockton On Tees
[depot_description] => Arriva Stockton on Tees Depot
[depot_postcode] => TS18 3AW
[depot_lat] =>
[depot_long] =>
[operating_company_id] => 1
[date_created] => 2014-02-14 10:24:17
[date_edited] =>
[edited_by] =>
[status] => active
[operating_company_name] => Arriva North East
[operating_company_description] => Arriva North East
[operating_company_lat] =>
[operating_company_long] =>
[operating_company_postcode] =>
[operating_group_id] => 1
)
[1] => stdClass Object
(
[depot_id] => 2
[depot_name] => Darlington
[depot_description] => Arriva Darlington Depot
[depot_postcode] => DH1 1TW
[depot_lat] =>
[depot_long] =>
[operating_company_id] => 1
[date_created] => 2014-02-14 10:24:17
[date_edited] =>
[edited_by] =>
[status] => active
[operating_company_name] => Arriva North East
[operating_company_description] => Arriva North East
[operating_company_lat] =>
[operating_company_long] =>
[operating_company_postcode] =>
[operating_group_id] => 1
)
[2] => stdClass Object
(
[depot_id] => 3
[depot_name] => Ashington
[depot_description] => Arriva Ashington Depot
[depot_postcode] => NE63 9UN
[depot_lat] =>
[depot_long] =>
[operating_company_id] => 2
[date_created] => 2014-02-14 10:46:05
[date_edited] =>
[edited_by] =>
[status] => active
[operating_company_name] => Arriva Northumbria
[operating_company_description] => Arriva Northumbria
[operating_company_lat] =>
[operating_company_long] =>
[operating_company_postcode] =>
[operating_group_id] => 1
)
[3] => stdClass Object
(
[depot_id] => 4
[depot_name] => Blyth
[depot_description] => Arriva Blyth Depot
[depot_postcode] => NE24 2AP
[depot_lat] =>
[depot_long] =>
[operating_company_id] => 2
[date_created] => 2014-02-14 10:46:05
[date_edited] =>
[edited_by] =>
[status] => active
[operating_company_name] => Arriva Northumbria
[operating_company_description] => Arriva Northumbria
[operating_company_lat] =>
[operating_company_long] =>
[operating_company_postcode] =>
[operating_group_id] => 1
)
我想所以在這個例子中有2個倉庫落在它下面創建基於「運營公司名稱」的OPTGROUP。
在我看來,我目前只是使用foreach循環來創建下拉菜單。
<select name="depot_id" class="form-control">
<?php foreach($depots as $depot): ?>
<optgroup label="<?php echo $depot->operating_company_name; ?>">
<option value="<?php echo $depot->depot_id; ?>"><?php echo $depot->depot_name; ?></option>
</optgroup>
<?php endforeach; ?>
</select>
這如下產生下拉....
我(如果可能)在循環如何可以把每一個工作組和車廠在一起嗎?
如果需要,可以給我的MySQL查詢。
感謝
我認爲你將不得不使用雙的foreach循環來創建你想要的 – Newbi3

嗨@ Newbi3我是雙重循環雖然? – StuBlackett
