博主之前做勤工助學系統的時候的導入導出的模板功能
先總結下幾個問題與難點:
1、execl表格類型大小的判定
2、加載模板後的每個表格的屬性（如A1、B1等）一定要確認
3、與數據庫的數據交互一定要添加事務處理
4、最後就是一些基礎的配置了
查考模板
勤工助學考勤表
學生積分統計表
首先引入庫類
use PHPExcel_IOFactory;
use PHPExcel;
導入視圖:
<form action="{:url('/index/bmbb/importExcel')}" method="post" enctype="multipart/form-data">
<h5>考勤數據上傳</h5>
<input type="file" name="file"><br/>
<input type="submit" value="導入考勤數據" class="btn btn-bb" style="width:200px; height:30px;" name="sub">
<input type="submit" value="導入積分數據" class="btn btn-primary" style="width:200px; height:30px;"name="sub">
</form>
導入方法:
public function importExcel(){
vendor ( "PHPExcel.PHPExcel" ); // 獲取PHPExcel類
$excel = new \PHPExcel ();
$file = request ()->file ( 'file' );
if(empty($file)){
$this->error("文件不能爲空","index/bmbb/import");
}
$info = $file->validate ( [
'size' => 15678,
'ext' => 'xlsx,xls,csv'
] )->move ( ROOT_PATH . 'public' . DS . 'excel' );
if ($info) {
$exclePath = $info->getSaveName (); // 獲取文件名
$file_name = ROOT_PATH . 'public' . DS . 'excel' . DS . $exclePath; // 上傳文件的地址
$objReader = \PHPExcel_IOFactory::createReader ( 'Excel2007' );
$obj_PHPExcel = $objReader->load ( $file_name, $encode = 'utf-8' ); // 加載文件內容,編碼utf-8
// echo "<pre>";
$excel_array = $obj_PHPExcel->getsheet ( 0 )->toArray (); // 轉換爲數組格式
$arr = reset ( $excel_array );//獲得標題
$yeararr=explode("年",trim($arr[0])); //切割字符串獲得日期
$moutharr=explode("月",substr(trim($arr[0]), 7));
$day=explode("日",substr($arr[0], 11));
if((float)$moutharr[0]<10){
$moutharr[0]="0".$moutharr[0];
}
$date=$yeararr[0]."-".$moutharr[0]; //年月
for ($i=0;$i<3;$i++){ //刪除不需要的數組
unset($excel_array[$i]);
}
$arr=array_values($excel_array);//重新建立索引
$mesarr = reset ( $excel_array );//拿第一條數組 下表4開始是日期1，34爲31
unset ( $arr [0] );
$arr=array_values($arr);
//判斷要導入的文件
if(input('sub')=="導入考勤數據"){
$trans_result = false;
try{
Db::startTrans();
foreach ($arr as $k =>$v){
$res["status"]="審覈通過";
for ($i=4;$i<35;$i++){
if($v[$i]!=null){
$res["studentId"]=$v[2];
$res["worktime"]=(float)$v[$i];
$res["date"]=$date."-".$v[$i]." ".date("H:i:s");
$res["admin"]=$v[38];
$list=Db::table('sign')
->insert($res);
}
}
}}
catch (\Exception $e) {
$trans_result = false;
//判斷中間是否有錯誤
}
}
else if(input('sub')=="導入積分數據"){
$date=$yeararr[0]."-".$moutharr[0]."-".$day[0];//日
$trans_result = false;
try{
Db::startTrans();
foreach ($arr as $k =>$v){
if($v[1]!=null){
$data["xh"]=$v[1];//取出學號
$data["xzjf"]=$v[2];//取出新增積分
$data["bz"]=$v[3];//取出備註
$data['shij']=$date;
$list=Db::table('xsjfjlb')
->insert($data);
}
}
}catch (\Exception $e) {
$trans_result = false;//判斷中間是否有錯誤
}
}
if ($trans_result === false) {
Db::rollback();
$this->error('導入失敗，格式錯誤','index/Bmbb/import');
} else {
Db::commit();
unset($info);
//一定要unset之後才能進行刪除操作，否則請求會被拒絕
$this->success('導入成功','index/Bmbb/import');
}
}
}
導出模板視圖:
<div class="col-lg-3"><input type="submit" name="sub" value="考勤彙總表下載" class="btn btn-bb" style="width:200px; height:50px;"></div>
<div class="col-lg-2"><input type="submit" name="sub" value="學生積分彙總表下載" class="btn btn-primary" style="width:250px; height:50px;"></div>
