PHP/Wordpress 查看 post 是否在类别中，然后显示图标。部分工作

Question

http://104.152.110.248/~baron/category/recipes/ - 我正在处理的网站

所以我正在做的是，当 post（收件人）属于某个类别时，我希望相应的图标出现在 post 的标题旁边. 例如，蟹饼属于鱼类别，因此它应该只在标题旁边显示鱼图标。而 Filet Mingion 只在牛肉类别中，所以它应该只显示牛图标。

我遇到的问题是，如果有任何 post 具有指定的牛肉类别，它会为所有 post 显示一个牛肉图标。虽然我希望它只显示分配给牛肉类别的 post。

这是我目前使用的代码。

    <?php 
    if ($all_the_tags);
    $all_the_tags = get_categories();
    foreach($all_the_tags as $this_tag) {
        if ($this_tag->name == "Spicy" ) {
    ?>
        <img class="icons" src="http://104.152.110.248/~baron/wp-content/themes/Baron/img/icons/Chili Pepper Filled.png">

    <?php   } else if ($this_tag->name == "Chicken" ) { ?>

                <img class="icons" src="http://104.152.110.248/~baron/wp-content/themes/Baron/img/icons/Chicken Filled.png">

    <?php   } else if ($this_tag->name == "Vegetables" ) { ?>

                <img class="icons" src="http://104.152.110.248/~baron/wp-content/themes/Baron/img/icons/Tomato Filled.png">

    <?php   } else if ($this_tag->name == "Fish" ) { ?>

                <img class="icons" src="http://104.152.110.248/~baron/wp-content/themes/Baron/img/icons/Fish Food Filled.png">

    <?php   } else if ($this_tag->name == "Pork" ) { ?>

                <img class="icons" src="http://104.152.110.248/~baron/wp-content/themes/Baron/img/icons/Pig.png">

    <?php   } else if ($this_tag->name == "Beef" ) { ?>

                <img class="icons" src="http://104.152.110.248/~baron/wp-content/themes/Baron/img/icons/Cow Filled.png">

    <?php   } else {    
            // it's neither, do nothing
    ?>
            <!-- not tagged as one or the other -->
    <?
    }
}
?>

试试这个，用下面的代码替换你的代码：

<?php 
        if (has_category("Spicy",get_the_id())) {
    ?>
        <img class="icons" src="http://104.152.110.248/~baron/wp-content/themes/Baron/img/icons/Chili Pepper Filled.png">

    <?php   } else if (has_category("Chicken",get_the_id())) { ?>

                <img class="icons" src="http://104.152.110.248/~baron/wp-content/themes/Baron/img/icons/Chicken Filled.png">

    <?php   } else if (has_category("Vegetables",get_the_id())) { ?>

                <img class="icons" src="http://104.152.110.248/~baron/wp-content/themes/Baron/img/icons/Tomato Filled.png">

    <?php   } else if (has_category("Fish",get_the_id())) { ?>

                <img class="icons" src="http://104.152.110.248/~baron/wp-content/themes/Baron/img/icons/Fish Food Filled.png">

    <?php   } else if (has_category("Pork",get_the_id())) { ?>

                <img class="icons" src="http://104.152.110.248/~baron/wp-content/themes/Baron/img/icons/Pig.png">

    <?php   } else if (has_category("Beef",get_the_id())) { ?>

                <img class="icons" src="http://104.152.110.248/~baron/wp-content/themes/Baron/img/icons/Cow Filled.png">

    <?php   } else {    
            // it's neither, do nothing
    ?>
            <!-- not tagged as one or the other -->
    <?
    }
?>
