Question

我开发的发票可以在用户点击“添加”按钮生成新字段时生成新的输入字段。然后在文档的最后我做了一个＆＃34; GET PDF＆＃34;一旦准备就绪，您可以使用该按钮获取发票的PDF副本。为了实现这一点，我一直在使用FPDF库，到目前为止，应用程序运行良好，除了一件事。 PDF文档必须基本上单独构建，我找不到一个好方法让PHP查看我构建应用程序的文件，并检索所有值的名称属性，以便注入它们在我在不同文件中制作的FPDF模板中。我是PHP的新手，我不知道如何解决这个问题。包含发票应用程序的文件名为index.php，包含PDF模板的文件名为pdf.php

in index.php:
<form action="pdf.php" method="post">
 <div class="inputForms">
  <div id="input_fields" class="input_fields_wrap">
    <div class="new"><input  name="description" class="description"       type="text" maxlength="255" placeholder="Enter Description" value=""/>
                    <input  name="r" class="rate qty" type="text"  maxlength="255" placeholder="0" size="5" value=""/>
                    <input  name="p" class="pack price" type="text" maxlength="255" placeholder="$ 0.00" size="5" value=""/>
                    <input id="amount" class="amount" name="amount"   type="text"></div>
</div>
 </div>
</form>

in pdf.php:

<?php

$invoiceNumber = $_POST['InvoiceNumber'];
$clientName = $_POST['clientName'];
$address = $_POST['address'];
$phone = $_POST['phone'];
$insurance_name = $_POST['insurance_name'];

Answer 1

我会使用＆＃34; field_01＆＃34;，＆＃34; field_02＆＃34;等模式命名新字段。然后，您可以像这样循环创建的POST字段：

foreach ($_POST as $key=>$value){
if (substr($key,0,6) === "field_"){
        $pdf->Cell(140,10,"$value",1,1,"L");
    }
}

Answer 2

这是一种简单的方法：

通过使用循环：

注意：您可以随时循环播放多次，但您可以通过以下方式使其动态化：

$_POST

注意：如果您在表单中使用POST方法，则... "SituacaoTributaria": [{ "value": 00, "situacao": "00 - Tributada Integralmente" }, { "value": 10, "situacao": "10 - Tributada com Cobrança de ICMS por ST" }, ...包含所有输入字段值，因此它将计算所有这些输入字段，然后它将根据字段数量......！
