从 Laravel 导出 PDF

Question

我正在尝试以 PDF 格式导出 table，但我有一个 foreach，我想从 foreach 导出所有数据，但不适用于所有数据，仅适用于一行。

代码如下：

foreach ($posts as $post) {
    $html = '<div class="table-scrollable">
                    <table id="posts" class="table table-bordered table-hover">
                        <thead>
                            <tr>
                                <th>Id</th>
                                <th>Name</th>
                                <th>Title</th>
                            </tr>
                        </thead>
                        <tbody id="body"><tr>
                            <td>'
            . $post->id . ' 
                            </td>
                            <td>' .
            $post->name .
            '</td>
                            <td>'
            . $post->title .
            '</td> 
                </tr>
               </tbody>
            </table>
        </div>';
}
return PDF::load($html, 'A4', 'portrait')->download('my_pdf');

在 foreach 构造中，您覆盖了 $html 变量，您需要在 foreach 之前初始化 $html 并使用串联赋值 [=] 添加到字符串的末尾 html 14=]

$html = '';
foreach ($posts as $post) {
        $html .= '<div class="table-scrollable">
                        <table id="posts" class="table table-bordered table-hover">
                            <thead>
                                <tr>
                                    <th>Id</th>
                                    <th>Name</th>
                                    <th>Title</th>
                                </tr>
                            </thead>
                            <tbody id="body"><tr>
                                <td>'
                . $post->id . ' 
                                </td>
                                <td>' .
                $post->name .
                '</td>
                                <td>'
                . $post->title .
                '</td> 
                    </tr>
                   </tbody>
                </table>
            </div>';
}
return PDF::load($html, 'A4', 'portrait')->download('my_pdf');
