Question

我在管理Wordpress的情况有些麻烦。我想要的是在用户编辑部分创建选项卡式界面。我没有dommanipulation的经验，所以我不知道，什么是最好的解决方案。现在我有preg_replace函数的ok代码，但我需要在多语言管理区域中通过自定义函数命令一些部分。谢谢

$html = '<div id="container">';
$html = '<h2>TAB1</h2>';
$html .= '<table><tr><td>SECTION1</td></tr></table>';
$html .= '<h2>TAB2</h2>';
$html .= '<table><tr><td>SECTION2</td></tr></table>';
$html .= '<h2>TAB3</h2>';
$html .= '<table><tr><td>SECTION3</td></tr></table>';
$html .= '<h2>TAB4</h2>';
$html .= '<table><tr><td>SECTION4</td></tr></table>';
$html .= '<hr>';
$html .= 'some content append to last section';
$html .= '</div>';

好的，我找到了。这是在编辑用户配置文件的部分中在Wordpress管理中创建选项卡式界面。但是，我现在，代码的质量不是那么好，但它有效：）

add_action( 'current_screen', array( 'change_profile_page' );
function change_profile_page(){
    $screen = get_current_screen();
    if ( 'user-edit' === $screen->base || 'profile' === $screen->base){
        add_action( 'admin_head', 'change_profile_page_start' );
        add_action( 'admin_footer', 'change_profile_page_end' );
    }
}


function tabify_profile_options( $html ) {
    $dom = new DOMDocument();
    $dom->strictErrorChecking = false;
    $dom->preserveWhiteSpace = true;
    libxml_use_internal_errors(true);
    $dom->loadHTML(mb_convert_encoding( $html, 'HTML-ENTITIES', 'UTF-8'));
    libxml_clear_errors();
    $xpath = new DOMXPath($dom);

    $tab = array();
    foreach ($xpath->query('//form[@id="your-profile"]//h2 | //form[@id="your-profile"]//h3') as $e) {
        $parent = $xpath->query('following-sibling::table', $e);
        if ($parent->length > 0) {
            $tab[] = array( 'title' => trim($e->nodeValue), 'content' => $parent);
            $e->parentNode->removeChild($e);
            $parent->item(0)->parentNode->removeChild($parent->item(0));
        }
    }

    $order = apply_filters( 'profile_options_order', array(1,4,2));
    uksort($tab, function($key1, $key2) use ($order) {
        $a = array_search($key1, $order);
        $b = array_search($key2, $order);
        if($a === false && $b === false) return 0;
        else if ($a === false) return 1;
        else if ($b === false) return -1;
        else return $a - $b;
    });

    $i = 0;
    $tabs = '';
    $content = '';
    $more = '';
    foreach($tab as $value){
        $tabs .= '<a href="javascript:;" class="nav-tab' . ($i==0 ? " nav-tab-active" : "" ) . '">' . apply_filters( 'profile_options_title', apply_filters( 'profile_options_' . ($i+1) . '_title', $value['title'] ) ) . '</a>';

        if ($i == 1) {
            foreach ($xpath->query('//form[@id="your-profile"]//label[@for="send_password"]/ancestor::table[1]') as $e) {
                $more .= $e->ownerDocument->saveHTML( $e );
                $e->parentNode->removeChild($e);
            }
        }
        $content .= '<section' . ($i!=0 ? ' class="hidden"' : '' ) . '>' . apply_filters( 'profile_options_' . ($i+1) . '_content' , $dom->saveHTML( $value['content']->item(0) ) . $more ) . '</section>';
        $more = '';
        $i++;
    }

    $rest = '';
    $submit = '';
    foreach ($xpath->query('//form[@id="your-profile"]/*') as $e) {
        if ( $e->getAttribute('class') != 'submit' ) {

        } else {
            $submit .= $e->ownerDocument->saveHTML( $e );
        }
        $e->parentNode->removeChild($e);
    }

    $content = preg_replace('~>\s+<~', '><', $content);
    $content = preg_replace('/(\<input type="text" name="user_login"[^>]+)(disabled)([^>]+)(>)(\<span+)(.*?)<\\/span>/', '${1}${3}${4}', $content);

    $rest = str_replace('<hr><hr>', '', $rest);

    $html = '

function change_profile_page_start() {
