thinkphp中用PHPExcel导出excel表—ajax方法

首先在前台html页面中点击某个控件来导出excel，这里用ajax的click方法实现实现点击事件，那怎么跟PHPExcel联系起来呢，请看代码：

HTML中jQ部分：

//导出excel
$("#daochu").click(function(){
var vkorg = $("#VKORG option:selected").val();
if(vkorg == ""){
var vkorgs = $("#VKORG option").map(function(){
return $(this).val();
}).get().join(",");
vkorg = vkorgs;
}
var kkber = $("#KKBER option:selected").val();
var kunnr = $("input[name='Kunnr']").val();
var name1 = $("input[name='Name1']").val();
var ym1 = $("input[name='YM1']").val();
var ym2 = $("input[name='YM2']").val();
$.ajax({
type:'post',
url:"{:U('OrderReleasReport/getexcel')}",
data:{vkorg:vkorg,kkber:kkber,kunnr:kunnr,name1:name1,ym1:ym1,ym2:ym2},
datatype:'json',
success:function(data){
location.href="../"+data.url;
}
})
})

将获取的值通过ajax传到后台，根据条件来查询相应的数据：

//导出excel
public function getexcel(){
$vkorg = $_POST['vkorg'];
$kkber = $_POST['kkber'];
$kunnr = $_POST['kunnr'];
$name1 = $_POST['name1'];
$ym1 = $_POST['ym1'];
$ym2 = $_POST['ym2'];
$where = " and 1=1 ";
if(!empty($vkorg)){
$where .= " and a.vkorg in ('".$vkorg."')";
}

if(!empty($kkber)){
$where .= " and a.kkber='".$kkber."'";
}
if(!empty($kunnr)){
$where .= " and a.kunnr like '%".$kunnr."%'";
}
if(!empty($name1)){
$where .= " and a.Name1 like '%".$name1."'";
}
if(!empty($ym1)){
$where .= " and  ApplyDate >= '".$ym1."'";
}
if(!empty($ym2)){
$where .= " and ApplyDate <= '".$ym2."'";
}
$expTitle = "放货查询";
$expCellName = array(
array('KKBER','信控范围'),
array('Kunnr','客户代码'),
array('name1','客户名称'),
array('ApplyDate','申请日期'),
array('Amount','订单金额'),
array('Amount','最终审批人'),
array('Amount','审批意见'),
array('Amount','备注'),
);
$expTableData = M()->query("select row_number() OVER (order by a.vkorg,a.kkber,a.kunnr) as rn,a.*,b.name1 from TB_REPORT_OrderApplication2 a inner join tb_crm_kna1 b on a.kunnr=b.kunnr where 1>0 $where");
$this->exportExcel($expTitle,$expCellName,$expTableData);
}

再调用exportExcel方法：

//PHPExcel导入导出的方法
protected function exportExcel($expTitle,$expCellName,$expTableData){
$xlsTitle = iconv('utf-8', 'gb2312', $expTitle);//文件名称
$fileName = time();//导出excal 文件名称
$cellNum = count($expCellName);//有多少列
$dataNum = count($expTableData);//有多少行
vendor("Excel.PHPExcel");//引入PHPExcel文件
ini_set("memory_limit", "1024M");
$objPHPExcel = new \PHPExcel();//实例化PHPExcel类库，相当于新建一个Excel表
$cellName = array('A','B','C','D','E','F','G','H','I','J','K','L','M','N','O',
'P','Q','R','S','T','U','V','W','X','Y','Z', 'AA','AB','AC','AD','AE',
'AF','AG','AH','AI','AJ','AK','AL','AM','AN','AO','AP','AQ','AR','AS','AT',
'AU','AV','AW','AX','AY','AZ');
//在第二行插入每列的标题
for($i=0;$i<$cellNum;$i++){
$objPHPExcel->setActiveSheetIndex(0)->setCellValue($cellName[$i].'1', $expCellName[$i][1]);
}
//从第三行开始插入数据
for($i=0;$i<$dataNum;$i++){
for($j=0;$j<$cellNum;$j++){
$objPHPExcel->getActiveSheet(0)->setCellValue($cellName[$j].($i+2), $expTableData[$i][$expCellName[$j][0]]);
}
}
$objSheet = $objPHPExcel->getActiveSheet();//获取当前活动sheet
$objSheet->setTitle('sheet1');//给当前的活动sheet起个名称
header('pragma:public');
header('Content-type:application/vnd.ms-excel;charset=utf-8;name="'.$xlsTitle.'.xlsx"');
header("Content-Disposition:attachment;filename=$fileName.xlsx");//attachment新窗口打印inline本窗口打印
header('Cache-Control: max-age=0');
$objWriter = new \PHPExcel_Writer_Excel2007($objPHPExcel);
$response = array(
'success' => true,
'url' => $this->saveExcelToLocalFile($objWriter, $fileName)
);
if ($response) {
$this->ajaxReturn($response, "json");
}
}

得到文件名再来拼接文件的路径，并将其保存：

//ajax导出用到的方法
function saveExcelToLocalFile($objWriter,$filename){
$filePath = './Public/excel/'.$filename.'.xlsx';
$objWriter->save($filePath);
return $filePath;
}

这样用ajax传递参数实现excel文件的导出就实现了。
