“alt=”推荐信“>

未从中显示的部分 所有输入

<span> <? php echo $ testimonials ['small_title']; ?> </ span>
<h2> <? php echo $ testimonials ['main_title']; ?> </ h2>
<? php echo $ testimonials ['description']; ?>

1-基于代码的get_字段(“推荐”)需要是一个数组,因此最好的方法是为该函数指定默认值数组,如:

$testimonials = get_field('testimonials', array(
    'small_title' => '',
    'main_title' => '',
    'description' => ''
));
echo $testimonials['small_title'];
echo $testimonials['main_title'];
echo $testimonials['description'];
echo isset($testimonials['small_title']) ? $testimonials['small_title'] : '';
echo isset($testimonials['main_title']) ? $testimonials['main_title'] : '';
echo isset($testimonials['description']) ? $testimonials['description'] : '';
因此,如果字段不是数组或null,则通过这种方式设置默认值,因为有时,如果数据库中没有记录当前post的数据,则此函数将返回null

2-以下字符串通过给定键获取数组$ESTIONAL值:

$testimonials = get_field('testimonials', array(
    'small_title' => '',
    'main_title' => '',
    'description' => ''
));
echo $testimonials['small_title'];
echo $testimonials['main_title'];
echo $testimonials['description'];
echo isset($testimonials['small_title']) ? $testimonials['small_title'] : '';
echo isset($testimonials['main_title']) ? $testimonials['main_title'] : '';
echo isset($testimonials['description']) ? $testimonials['description'] : '';
但是,如果数组$commentials中不存在密钥,该怎么办? 您需要将PHP函数与速记条件if语句一起使用,以避免出现警告消息或破坏html代码

这是正确的方法:

$testimonials = get_field('testimonials', array(
    'small_title' => '',
    'main_title' => '',
    'description' => ''
));
echo $testimonials['small_title'];
echo $testimonials['main_title'];
echo $testimonials['description'];
echo isset($testimonials['small_title']) ? $testimonials['small_title'] : '';
echo isset($testimonials['main_title']) ? $testimonials['main_title'] : '';
echo isset($testimonials['description']) ? $testimonials['description'] : '';

我希望这将帮助您解决问题

如果您在单个页面中使用它,它工作正常,如果您需要它在主页中工作,您需要在ACF功能中添加页面id,如

$testimonials = get_field('testimonials',the_ID);

谢谢你的回复我在这里写了什么,很抱歉我是Wordpress的初学者,我的知识在PHP$Estimationals=get_field('Estimationals',array('small_title'=>'here','main_title'=>'here','description'=>'here')中很简单;可以将其保留为空,也可以使用默认标题替换空值
