我正在使用ACF，如果custom_field号码

Can you please tell me how to do that?

我假设你想获得赌场评级并根据出现的内容显示不同的课程？

在这种情况下，您可以使用此代码：

if( $post_objects ):

    foreach( $post_objects as $post_object ):

        $casino_rating = get_field("casino_rating", $post_object->ID);

        // This part here will decide what class to get
        if( $casino_rating < 30 ){

            echo 'class="color1"';

        } elseif( $casino_rating < 50 ){

            echo 'class="color2"';

        } elseif( $casino_rating < 90 ){

            echo 'class="color3"';

        }


    endforeach;


endif;

您可能需要小心，但如果该元素没有附加其他类，请确保仅输出class=，否则会出现HTML错误。

稍微更紧凑的版本应该达到同样的目的

if( $post_objects ):
    foreach( $post_objects as $post_object ):
        $rating = get_field("casino_rating", $post_object->ID);

        $color = ($rating >= 31) ? "color2" : "color1";
        $color = ($rating >= 51 ) ? "color3" : $color;
        echo 'class="'.$color.'"';

    endforeach;
endif;

或者如果您打算使用它，可以在页面底部创建一个功能

 function color($rating) {
        $color = ($rating >= 31) ? "color2" : "color1";
        $color = ($rating >= 51 ) ? "color3" : $color;
        return $color;
    }

然后你可以做

 if( $post_objects ):
        foreach( $post_objects as $post_object ):
            $rating = get_field("casino_rating", $post_object->ID);
            echo 'class="'.color($rating).'"';
        endforeach;
    endif;
