脚本宝典收集整理的这篇文章主要介绍了php – 如何在服务器端处理模式下使用JOIN进行数据库查询,脚本宝典觉得挺不错的,现在分享给大家,也给大家做个参考。
如何使用自定义查询使用多个表和JOIN而不会改变太多是我的代码?
所以我有这个:
<table id="CustomerList" class="table table-striPEd table-bordered" cellspacing="0" width="100%"> <thead> <tr> <th colspan="7"> <center>Customer Information<center></th> <th colspan="1"> <center>Actions<center></th> </tr> <tr> <th>ID</th> <th>First Name</th> <th>Last Name</th> <th>Gender</th> <th>Phone Number</th> <th>Country</th> <th>Postcode</th> <th>EdIT</th> <!-- <th>Edit</th> <th>Delete</th> --> </tr> </thead> <tbody> </tbody> </table>
阿贾克斯
<script type="text/javascript"> $(document).ready(function() { $.fn.dataTable.ext.legacy.ajax = true; VAR table = $('#CustomerList').DataTable( { "PRocessing": true,"serverSide": true,"ajax": "api/customer/all","columnDefs": [ { "targets": 7,"render": function(data,type,row,Meta){ // return '<a href="/qms/public/customer/' + row[0] + '/edit">Edit</a>'; return "<a class='BTn btn-small btn-info' href='<?PHP echo URL::to('customer').'/';?>"+row[0]+"/edit'><span class='glyphicon glyphicon glyphicon-edit' aria-hidden='true'></span></a>"; } } ] }); var tt = new $.fn.dataTable.TableTools( $('#CustomerList').DataTable() ); $( tt.fnContainer() ).insertBefore('div.dataTables_wrapper'); });

在我的控制器中,您可以看到$aColumns,其中包含我希望在表客户中获得的表列
$query = "SELECT a.id as crmid,b.name,a.title,a.firstname,a.surname,a.disposition,a.gross,a.created_at,a.phone_num FROM forms a INNER JOIN users b ON a.agent_id = b.id;";
