在模板中
<?php wp_login_form( array( \'echo\' => true ) ); ?>
源代码
<p class="login-remember">
<label>
<input name="rememberme" type="checkbox" id="rememberme" value="forever"> Remember Me
</label>
</p>
我想在后面添加一个span标记
Remember meRemember Me <span class="custom-styled-checkbox"></span>
我试图向标签中添加一些html，但没有成功：
$args = array(
\'label_remember\' => __( \'Remember Me <span class="custom-styled-checkbox"></span>\' ),
);
wp_login_form( $args );
也没做过这么简单的事
function custom_checkbox_form($output) {
$search = array(\'<p class="login-remember"><label>\',\'</label></p>\');
$replace = array(\'<p class="login-remember"><label>\', \'<span class="custom-styled-checkbox"></span></label></p>\');
return str_replace( $search, $replace, $output );
}
add_filter( \'login_head\', \'custom_checkbox_form\', 99, 1 );
非常感谢您的帮助。

这个label_remember 论点仅用于更改文本；HTML将被转义，因此在这里不起作用。
相反，登录表单的HTML可以在输出之前进行解析和修改：
// Get the HTML for the login form
$login_form = wp_login_form( [ \'echo\' => false ] );
// Create an instance of DOMDocument
$dom = new \\DOMDocument();
// Populate $dom with our login form, making sure to handle UTF-8, otherwise
// problems will occur with UTF-8 characters.
$dom->loadHTML( mb_convert_encoding( $login_form, \'HTML-ENTITIES\', \'UTF-8\' ) );
// Create an instance of DOMXpath and get the <p class="login-remember"> node
$xpath = new \\DOMXpath( $dom );
$remember = $xpath->query( \'//p[@class="login-remember"]\' );
// Iterate over the $remember node...
foreach ( $remember as $container ) {
// Create the <span> element
$checkbox_span = $dom->createElement( \'span\' );
// Create the class attribute
$checkbox_span_attr = $dom->createAttribute( \'class\' );
// Set the value of the class attribute
$checkbox_span_attr->value = \'custom-styled-checkbox\';
// Add class="custom-styled-checkbox" to the <span> element
$checkbox_span->appendChild( $checkbox_span_attr );
// Append the completed <span class="custom-styled-checkbox"></span> element
// to <p class="login-remember"><label>
//$container->childNodes[0]->appendChild( $checkbox_span ); // Fails on PHP < 5.6.3?
$container->childNodes->item(0)->appendChild( $checkbox_span );
}
// Save the updated HTML to $login_form and output it.
$login_form = $dom->saveHTML();
echo $login_form;
