I found that there are many pages to export excel table for recent projects. I think this is also our common function. Now I can export it skillfully, but I remember that when I first exported it, there were some detours, so now I will record my export under the project of exhop framework (in fact, the export principles of Excel under different frameworks are all the same Almost)

 <a href="javascript:;" id="export_all" class="coolbg">export</a>

<script>
    //Derived data
    $('#export_all').click(function(){
        window.open('index.php?app=craft_order&act=export', '_blank');
    });
</script>

Controller
```
// Derived data
public function export() {
$result = $this->_oaOrderModel->getAllOrderListForManager($this->store_id, $orderSn=null, $buyer_id=null, $buyer_name=null, $consignee=null, $phone=null, $company_name=null, $status=null, $s_time=null, $e_time=null, $page=null, $listRows=null, $execl=true); //This is the code to get data - model
$orderList = $result['orderList'];
if (!empty($orderList)) {
$j = 1;
$stmt = array();
foreach ($orderList as $val) {
$stmt[$j]['website ID'] = $val['store_id'];
$stmt[$j]['Order information'] = $val['order_sn'];
$stmt[$j]['Commodity information'] = $val['inventory_sn_count_chinese'];
$stmt[$j]['Process selection'] = $val['craft_count_chinese'];
$stmt[$j]['Total quantity of goods'] = $val['real_goods_total_count'];

Note: PHPExcel(); / / download this method and put it into the public method

Sometimes we can think more about these problems and look at its principle. We understand that we will do other things next time. But the most important thing is to know how to record. Our memory is not as good as we think
