[英]If page has posts in certain category - wordpress
I have a client built site that I am adding some functionality too - I don't usually develop using Wordpress. 我有一个客户端构建的网站,我也添加了一些功能-我通常不使用Wordpress进行开发。 They have built pages using Visual Composer to display posts from varying categories 他们使用Visual Composer构建了页面来显示不同类别的帖子
If the post is within a certain category 'Deals' I want to do stuff … non-working code (in functions.php) below: 如果帖子属于某个类别“交易”,那么我想做些…下列无效代码(在functions.php中):
function deals () {
if ( in_category('Deals') ) {
echo '<style>.entry-thumb{display: none !important;}</style>';
}
}
Calling function from within child theme page template. 从子主题页面模板中调用功能。
Any help would be great thanks 任何帮助将不胜感激
You should try is_category() function like this: 您应该尝试使用is_category()函数,如下所示:
function deals () {
if ( is_category('Deals') ) {
echo '<style>.entry-thumb{display: none !important;}</style>';
}
}
You can check if current post is in category by using 您可以使用来检查当前帖子是否在类别中
if( has_category('Deals') ) { // do stuff here }
If $post
global variable is set has_category('Deals')
will be ok. 如果设置了$post
全局变量, has_category('Deals')
就可以了。 Otherwise you will need to pass post ID as second parameter. 否则,您将需要传递帖子ID作为第二个参数。 https://developer.wordpress.org/reference/functions/has_category/ https://developer.wordpress.org/reference/functions/has_category/
PS If you are calling it in a loop it looks like you are trying to echo the same inline css multiple times. PS:如果您在循环中调用它,则好像您试图多次回显同一行内联CSS。 This will hide all .entry-thumb
s regardless of the category. 无论类别如何,这都将隐藏所有.entry-thumb
。 So it may be better to add a class to your deal
posts and then use something like .deal .entry-thumb{ display: none; }
因此,最好在deal
添加一个类,然后使用.deal .entry-thumb{ display: none; }
.deal .entry-thumb{ display: none; }
in your style.css. .deal .entry-thumb{ display: none; }
放在您的style.css中。
