如何在laravel中下载Excel文件

Question

我正在尝试下载一个工作正常的excel文件，但是由于我有一些json列，所以当我尝试包含这些列时，它不起作用。到目前为止，我已经尝试过了。

public function salarySheetExcel($id)
    {
        $headers = array(
            "Content-type" => "text/csv",
            "Content-Disposition" => "attachment; filename=salary-sheet.csv",
            "Pragma" => "no-cache",
            "Cache-Control" => "must-revalidate, post-check=0, pre-check=0",
            "Expires" => "0"
        );

        $salariesOfMonth = SalaryArchive::find($id)->salaries;
        $columns = array('EmployeeCode', 'EmployeeName', 'Weekends','holidays','leaves','absent','present','inform' ,'late','Basic', 'Allowances', 'Allowance Amount',
            'Gross', 'Bonus', 'Overtime Logs', 'Overtime Amount','Net Salary','Deduction Logs','Deduction','PF','Total Salary');

        $callback = function() use ($salariesOfMonth, $columns)
        {
           $file = fopen('php://output', 'w');
            fputcsv($file, $columns);

            foreach($salariesOfMonth as $salary) {


                $salary=array($salary->employee->employee_code,$salary->attendance_log, $salary->employee->name, $salaries ,
                    $salary->basic,  $salary->allowance_amount,$salary->gross,
                    $salary->bonus,  $salary->overtime_amount,$salary->net_salary,
                    $salary->deduction,$salary->pf,$salary->total_salary);
                fputcsv($file, $salary);
            }
            fclose($file);
        };
        return Response::stream($callback, 200, $headers);
    } 

它不起作用，但是当我删除$ salary-> attendance_log时，它的工作正常，因为它是我的json列。请帮我解决一下

Answer 1

JSON数据在字符串中包含引号，这就是它不起作用的原因。

使用下面的代码。

$salary=array($salary->employee->employee_code,addslashes($salary->attendance_log), $salary->employee->name, $salaries ,
                $salary->basic,  $salary->allowance_amount,$salary->gross,
                $salary->bonus,  $salary->overtime_amount,$salary->net_salary,
                $salary->deduction,$salary->pf,$salary->total_salary);
            fputcsv($file, $salary);

我认为您需要在添加到json_decode之前使用fputcsv。

$log = json_decode($salary->attendance_log, true);
$weekends = $log['weekends'];
$holidays = $log['holidays'];
$leaves   = $log['leaves'];
$absent   = $log['absent'];
$present   = $log['present'];
$inform   = $log['inform'];
$late   = $log['late'];


$salary=array($salary->employee->employee_code, $salary->employee->name, $weekends, $holidays, $leaves, $absent, $present, $inform, $late, $salaries ,
                $salary->basic,  $salary->allowance_amount,$salary->gross,
                $salary->bonus,  $salary->overtime_amount,$salary->net_salary,
                $salary->deduction,$salary->pf,$salary->total_salary);


fputcsv($file, array_merge($salary, $log));
