Php 如何在搜索表单中插入范围?(创世记)
当我呼叫时,它输出:Php 如何在搜索表单中插入范围?(创世记),php,wordpress,search,genesis,search-form,Php,Wordpress,Search,Genesis,Search Form,当我呼叫时,它输出: <form class="search-form"> <meta itemprop="target"> <input type="search"> <input type="submit"> </form> 正在寻找一种更安全的替代方案: add_filter( 'genesis_search_form', 'my_search_button' ); function my_search_butto
<form class="search-form">

正在寻找一种更安全的替代方案:
add_filter( 'genesis_search_form', 'my_search_button' );
function my_search_button( $form ) {
return str_replace(
'<input type="submit"',
'<span class="submit-icon"></span><input type="submit"',
$form
);
}
add_filter('genesis_search_form','my_search_button');
功能我的搜索按钮($form){
返回stru_替换(

$('form.search-form input[type=search]').after('<span class="submit-icon"></span>');
$('form.search-form input[type=search]')。在('')之后;
使用DOMDocument!以下是代码的工作版本:
如果您对DOMDocument没意见,这个版本更适合HTML5
add_filter( 'genesis_search_form', 'my_search_button' );
function my_search_button($form) {
$document = new DOMDocument();
$document->loadHTML($form);
$xpath = new DOMXPath($document);
$input = $xpath->query('//input[@type="submit"]');
$span = $document->createElement('span');
$span->setAttribute('class', 'sb-icon');
if ($input->length > 0) {
$input->item(0)->parentNode->insertBefore($span, $input->item(0));
}
$document->removeChild($document->doctype);
$document->replaceChild($document->firstChild->firstChild->firstChild, $document->firstChild);
$form_html = $document->saveHTML();
return $form_html;
}
只要函数不提供这样做的功能,您就无法做到这一点,如果允许它分叉函数并根据您的需要自定义它,您可以这样做。感谢您的回答,jQuery
确实更简单,但我们正在php
服务器端寻找解决方案。太棒了;它让您保持它是服务器端的,就像他想要的那样。以某种方式缓存结果也可能是有意义的,这样他就不必在每个请求中操作DOM块。
<?php
// Create a DOM Document
$dom = new DomDocument();
// Load your HTML

// Create a new <span>
$span = $dom->createElement('span', 'hello');
// Grab the <input elements (we dont have an ID)
$inputs = $dom->getElementsByTagName('input');
// Add the <span> between the inputs
$inputs->item(0)->parentNode->insertBefore($span, $inputs->item(1));
// By default when you loadHTML(), it generates doctype, html, head, and body tags. remove them!
