Php WordPress：使用过滤器在加载时显示特定类别

我有一个主题和一个公文包，它使用过滤器（所有、新、旧）来显示类别。然而，在加载时，我希望特定（“新”）类别是显示的唯一类别

然后，如果用户希望看到过去的产品，他们会单击“旧”等等

请记住，我将创建另一个公文包，该公文包的新项目将仅在第一次加载时显示

我试图找到答案已经好几个小时了，但我还没有找到

以下是portfolio php页面的代码：

这个问题与Wordpress本身无关，而是与您或您的主题用来排序数据的插件有关

在本例中，它使用的是过滤页面上显示的结果

通过在过滤方面解决问题，我们发现可以通过函数或按钮来完成过滤，在这种情况下，我们将两者结合使用，因为我们希望在单击时更改数据，但同时它已经需要按照您的要求进行过滤

所以，为了解决这个问题，同位素的函数文件中只有一行：

$container.isotope({
            itemSelector : '.element',
            filter: '.workshops'
        });

我刚刚加了最后一个

除此之外，您只需破解提供的代码，即可将“选定”类添加到按钮：

echo( '<ul id="filters" class="option-set">

                        <li><a href="#" data-filter="*" class="show-all">All</a></li>' );

                        foreach ( $categories as $category ) { ?>

                        <li>
                            <span class="sep">/</span>
                            <a href="#<?php echo $category->slug; ?>" <?php if($category->slug == 'workshops'): echo 'class="selected"'; endif;?>data-filter=".<?php echo $category->slug; ?>"><?php echo $category->name;?></a>
                        </li>

                        <?php 
                        }

                        echo( '</ul>' );

我很难理解你想要什么。你能显示工作页面的链接吗？@nunorbatista非常感谢你的回复。由于URL还没有上线，是否可以私下给它发消息？另外，这里有一个屏幕截图：这是用户第一次登陆时看到的。然而，我只希望看到“新”下的项目着陆时显示的过滤器，因此“旧”在着陆时不可见，仅在按下“旧”过滤器或“全部”时显示。但在着陆时，仅显示“新”下的项目将显示。我现在明白你想要什么了。你的代码非常大，你应该把它分成几个部分以便于阅读。我现在没有时间看，明天再看！我检查了你的代码，如果不检查网站，我将无法帮你。访问我的个人资料，访问我的网站并填写表格，我将从那里帮助你。@nu诺巴蒂斯塔太棒了！我填写了联系表。谢谢！太棒了！你帮了我很大的忙。谢谢！
