PHP是否只包含文件的指定部分？ [英] Can PHP include work for only a specified portion of a file?

问题描述

我有一个PHP include，它将html表单插入到另一个html表单中。当表单被包含时，我现在有两个表单标题。是否有我可以使用的php标签，这将允许我...

I have a PHP include that inserts an html form into another html form. When the form gets included I now have two form headers. Is there a php tag I could use that would allow me to...

<form id="orderform">

<!-- <?php for the include FROM here?> -->

PROD:<input class="ProductName" type="text" size="75">|
Discount:<input class="Discount" type="text" size="3">|
QTY:<input class="qty" type="text" size="6">|
Line/Total:<input class="LineTotal" type="text" size="9" disabled>

<!-- <?php for the include TO here?> -->

</form>

所以include会进入那个包含表单的文件并获取指定的HTML吗？

So the include would go into that file with the form in it and get the specified HTML?

这可能吗？

<?php 
$dom = new DOMDocument();
$html = 'phptest3.php';
$dom->loadHTMLFile($html);
$div = $dom->getElementById("divtagid");
echo $div->nodeValue;
?>

这只返回文本。如何在divtagid中获取HTML表单元素？

This only returns the text. How do I get the HTML form elements in the divtagid?

推荐答案

您最好查看php函数。

You should best look into php functions for this.

<?php
function form_tag_wrapper($form) {
  return '<form id="orderform">'. $form .'</form>';
}

function form_contents() {
  return 'PROD:<input class="ProductName" type="text" size="75">
          ...
          Line/Total:<input class="LineTotal" type="text" size="9" disabled>';
}
?>

您将使用此作为：

$form = form_contents();
print form_tag_wrapper($form);

或者，作为oneliner：

Or, as a oneliner:

print form_tag_wrapper(form_contents());
