Laravel PDF导出：如何根据id导出数据

Question

我想根据 id 导出数据，这样它就不会获取数据库中的所有数据，例如，如果站点是“http://127.0.0.1:8000/pengajuan/3” “/3”是我想从中导出的 'submission_id'，这是我的代码：

控制器

public function exportpdf()
    {
        $submissionDetail = SubmissionDetail::all();
    
        $pdf = PDF::loadview('pengajuan_detail.pdf',['submissionDetail'=>$submissionDetail]);
        return $pdf->stream();
    }

SubmissionDetail.php

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class SubmissionDetail extends Model
{
    protected $fillable = [
        'submission_id', 'nama_barang', 'image_path', 'jumlah', 'harga_satuan', 'harga_total', 'keterangan',
    ];
    public function submission()
    {
        return $this->belongsTo('App\Submission');
    }

    public function negotiation()
    {
        return $this->hasOne('App\Negotiation');
    }

    public function realization()
    {
        return $this->hasOne('App\Realization');
    }
}

怎么做？

Answer 1

此代码用于 exportpdf() 函数

// This will convert url string to array with '/' declimiter
$url = explode('/', url()->current()); // something like [..., '127.0.0.1:8000', 'pengajuan', '3']
$id = end($url); // result is 3

// Get Specific Submission detail with "where" function
$submissionDetail = SubmissionDetail::where('submission_id', $id)->first();

// Rest is just same
$pdf = PDF::loadview('pengajuan_detail', ['submissionDetail' => $submissionDetail]);
return $pdf->stream();

如果发生错误，它可能来自您的 PDF 模板（如果发生，您可以 post 错误）因为您直接使用 PDF 文件作为模板，而不是 blade 文件
