只是按照教程从头创建了一个自定义字段。我有一个网站链接字段。目前它只输出原始文本，没有链接。

那么，如何使此代码超链接：

<li><strong>Website:</strong> \'.$_imd_portfolio_website_output.\'</li>

完整代码：

function imd_portfolio_meta_box() {
    global $post;
    // get the custom field values as an array
    $values = get_post_custom( $post->ID );
    // extract the members of the $values array to their own variables (which you can see below, in the HTML code)
    extract( $values, EXTR_SKIP );

    // escape the output, just in case
    $allowed_html = array(
        \'a\' => array(
            \'href\' => array(),
            \'title\' => array()
        ),
        \'em\' => array(),
        \'strong\' => array()
    );
    $_imd_portfolio_details_output = wp_kses($_imd_portfolio_details[0], $allowed_html);
    $_imd_portfolio_client_output = wp_kses($_imd_portfolio_client[0], $allowed_html);
    $_imd_portfolio_website_output = wp_kses($_imd_portfolio_website[0], $allowed_html);
    $_imd_portfolio_quote_output = wp_kses($_imd_portfolio_quote[0], $allowed_html);
    $output = \'<div class="review-box">
        <ul class="review-box-list">
            <li><strong>Details:</strong> \'.$_imd_portfolio_details_output.\'</li>
            <li><strong>Client:</strong> \'.$_imd_portfolio_client_output.\'</li>
            <li><strong>Website:</strong> \'.$_imd_portfolio_website_output.\'</li>
            <li><strong>Quote:</strong>\'.$_imd_portfolio_quote_output.\'></li>
        </ul>
    </div>\';
    return $output;
}

更新：问题已解决我已编辑代码；更改此行-

<li><strong>Website:</strong> \'.$_imd_portfolio_website_output.\'</li>

到该行-

<li><strong>Website:</strong><a href="http://\'.$_imd_portfolio_website_output.\'">\'.$_imd_portfolio_website_output.\'</a></li>

谢谢大家的帮助
