Laravel表格导入导出
在你项目根目录找到composer.json里的require添加如下
"require": {
"maatwebsite/excel": "^3.1"
},
执行更新
composer update
OR
composer require maatwebsite/excel
在config/app.php添加
'providers' => [
Maatwebsite\Excel\ExcelServiceProvider::class,
]
'aliases' => [
...
'Excel' => Maatwebsite\Excel\Facades\Excel::class,
]
发布资源命令:
php artisan vendor:publish --provider="Maatwebsite\Excel\ExcelServiceProvider"
假设导入学生execl:
创建文件
$row[5],
'class'=>$row[6],
'student_number'=>$row[7],
'student_name'=>$row[9],
'sex'=>$row[10],
'card'=>$row[11],
]);
}
Controller
public function import(Request $request):array {
$arr = \Maatwebsite\Excel\Facades\Excel::toArray(new StudentImport,$request->file('file'));
return ['code'=>200]
}
导出:
创建导出文件:
arr = $arr;
}
public function bindValue(Cell $cell, $value)
{
if (strlen($value) > 10) {
$cell->setValueExplicit($value, DataType::TYPE_STRING);
return true;
}
// else return default behavior
return parent::bindValue($cell, $value);
}
public function headings(): array
{
$where = $this->arr;
switch ($where['where']){
case 0: //未入住学生
$array = ['id','姓名','性别','年纪','班级','学号','证件','培养类型','入学时间','手机号','邮箱'];
break;
case 1:
$array = ['id','楼宇','层数','房间号','年纪','性别','朝向','类型','价格','总床位','空闲','床位编号','居住人'];
break;
case 2:
$array = ['id','楼宇','层数','房间号','年纪','性别','朝向','类型','价格','床位编号','居住人','总床位','空闲'];
break;
case 3:
$array = ['id','楼宇','层数','房间号','年纪','性别','朝向','类型','价格','总床位','空闲'];
break;
}
return $array;
}
headings()是自定义标题,在导出长数字的时候比如身份证,会形成1.0E之类的科学计算,这个时候需要判断类型,将其定义为String类型
public function bindValue(Cell $cell, $value)
{
if (strlen($value) > 10) {
$cell->setValueExplicit($value, DataType::TYPE_STRING);
return true;
}
// else return default behavior
return parent::bindValue($cell, $value);
}
继续控制器调用:
public function downXls(Request $request)
{
$data = $request->all();
return \Maatwebsite\Excel\Facades\Excel::download(new Execl($where), 'data.xls');
}
至此,Execl表格导入导出完成
