laravel dompdf 导出不导出我视图的所有内容

问题描述 投票：0回答：2

我目前正在使用 Laravel 9，laravel dompdf 包来导出我的文件，这是我得到的 pdf 文件，根本没有内容。我传递的数据没有显示在 PDF 中。

但是当我将其作为视图打开时，数据正确传递并且 CSS 工作得很好。这是它的样子：

这是我在视图上的代码：

<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="utf-8">
        <meta name="viewport" content="width=device-width, initial-scale=1">

      </head>
    
      <style>

dompdf 对 CSS 和样式非常挑剔...但首先，您应该始终将 

<style>
标签放在文档的 
<head>
标签内。如果不把它放在那里，不同的浏览器呈现内容的方式就会不一致，包括无头系统和 domPDF。

因此，将您的 

<style>
标签放入 
<head>
标签中，看看这是否有助于解决问题，如果没有，请尝试将您的样式转换为带有样式的表格，因为 dompdf 似乎比 div 更适合处理表格。

你应该关心语法：

@php $i = 1; @endphp 
@php $i++; @endphp
