我遇到了 appendXML() 的問題，它不會將表單附加到 HTML。現在我有這個代碼$domdocument = new DOMDocument();$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 = $domdocument->saveHTML();該代碼運行良好，并使用“formCLass”類簡單的 HTML 附加到 div，如文本和帶有文本的 div。但是，當涉及到附加表單時……嗯……那是另一回事。我也嘗試過使用$frag->nodeValue = $formHTML;代替$frag->appendXML($formHTML);但它仍然沒有工作......試$frag->textContent = $formHTML;會將表單輸出為文本，顯然這對我不起作用。我怎么解決這個問題？表格代碼：<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>

我剛剛使用您的代碼和我自己的一些 HTML 組合了一個非常簡單的測試用例，它似乎可以附加，如下所示。
您的表單的 HTML 是否有可能無效？
如果您仍然遇到問題，您能否在某處發布您的 HTML，以便我們可以嘗試一下，好嗎？
$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 輸出：
<!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>
