Question

我在wordpress网站上有一个代码（front-page.php），它剪切了文字并添加了＃34; ...＆＃34;如果文字超过35个字符，则为标题。剪切是可以的，但点总是可见的。是否可以仅在文本被剪切时添加？谢谢！

<div class="bxpd">   
    <h2><span><?= substr($post_title,0,35); ?></span>
    <a href="<?= get_post_permalink($post_id); ?>">
        <?= substr($postData->post_title, 0, 35)."..."; ?>              
    </a>
    </h2>
    <p><?= substr($postData->post_content,0,strpos($postData->post_content, ' ', 150))."..."; ?> </p>
</div>

Answer 1

只有在需要时才能调整代码并放置......

<div class="bxpd">   
                <h2><span><?= substr($post_title,0,35); ?></span>
                <a href="<?= get_post_permalink($post_id); ?>">
                <?= substr($postData->post_title, 0, 35)."..."; ?>

                </a>
                </h2>
                <p><?= substr($postData->post_content,0,strpos($postData->post_content, ' ', 150)).
(strlen($postData->post_content)>150?"...":""); 

?> </p>
           </div>

Answer 2

<div class="bxpd">   
<h2><span><?= substr($post_title,0,35); ?></span>
<a href="<?= get_post_permalink($post_id); ?>">
    <?=
        substr($postData->post_title, 0, 35). (strlen($postData->post_title) > 35 ? "..." : ""); 
    ?>              
</a>
</h2>
<p><?= substr($postData->post_content,0,strpos($postData->post_content, ' ', 150))."..."; ?> </p>

substring - 如果文本被剪切，最后添加....
