DOMDocument - appendXML() 不适用于表单
我遇到了 appendXML() 的问题，它不会将表单附加到 HTML。
现在我有这个代码
$domdocument = new DOMDocument();
$domdocument->loadHTML($html);
$domlookup = new DOMXPath($domdocument);
$formDivs = $domlookup->query("//*[contains(@class, 'formClass')]");
$frag = $domdocument->createDocumentFragment();
$frag->appendXML($formHTML);
for ($i = $formDivs->length - 1; $i > -1; $i--) {
$formDivs->item($i)->parentNode->appendChild($frag);
}
@$html = $domdocument->saveHTML();
该代码运行良好，并使用“formCLass”类简单的 HTML 附加到 div，如文本和带有文本的 div。但是，当涉及到附加表单时……嗯……那是另一回事。
我也尝试过使用
$frag->nodeValue = $formHTML;
代替
$frag->appendXML($formHTML);
但它仍然没有工作......
试
$frag->textContent = $formHTML;
会将表单输出为文本，显然这对我不起作用。
我怎么解决这个问题？
表格代码：
<form method="post">
<div class="fb-text form-group field-petname">
<label for="petname" class="fb-text-label">
"Pet Name"<span class="fb-required">*</span>
</label>
<input type="text" placeholder="Your Pet Name" required = "required" aria-required = "true" class="form-control" name="petname" id="petname">
</div>
<div class="fb-text form-group field-petowner">
<label for="petowner" class="fb-text-label">
"Pet owner"<span class="fb-required">*</span>
</label>
<input type="text" placeholder="Insert owner's name" required = "required" aria-required = "true" class="form-control" name="petowner" id="petowner">
</div>
<div class="fb-text form-group field-phone">
<label for="phone" class="fb-text-label">
"Phone number"<span class="fb-required">*</span>
</label>
<input type="text" placeholder="Phone number" required = "required" aria-required = "true" class="form-control" name="phone" id="phone">
</div>
<div>
<div id="goldenmembership">
<i class="fas fa-truck"></i>Free delivery!
</div>
</div>
<div class="fb-select form-group field-brand">
<label for="brand" class="fb-select-label">
What brand would your pet like?<span class="fb-required">*</span>
</label>

我刚刚使用您的代码和我自己的一些 HTML 组合了一个非常简单的测试用例，它似乎可以附加，如下所示。您的表单的 HTML 是否有可能无效？如果您仍然遇到问题，您能否在某处发布您的 HTML，以便我们可以尝试一下，好吗？$html = <<<HTML<html> <body> <div class="formClass"> <!-- Placeholder --> </div> </body></html>HTML;$formHtml = <<<HTML<form action="#" method="post"> <input type="text" id="test"/></form>HTML;$domdocument = new DOMDocument();$domdocument->loadHTML($html);$domlookup = new DOMXPath($domdocument);$formDivs = $domlookup->query("//*[contains(@class, 'formClass')]");$frag = $domdocument->createDocumentFragment();$frag->appendXML($formHtml);for ($i = $formDivs->length - 1; $i > -1; $i--) { $formDivs->item($i)->parentNode->appendChild($frag);}$html = $domdocument->saveHTML();echo $html;HTML 输出：<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd"><html> <body> <div class="formClass"> <!-- Placeholder --> </div> <form action="#" method="post"> <input type="text" id="test"></form></body></html>
