Wordpress 条件语句不起作用

Question

我正在设置一些条件语句来更改不同页面的页面布局。我的第一个条件是

if (is_page('15030')) {
}

里面的内容是首页的，效果很好。然后我的下一个说

elseif (is_page('Sales')){
}

而且它根本不起作用。我尝试使用页面名称、页面 ID、将 elseif 更改为 if、使用 in_category - 根本没有显示任何内容。知道我应该寻找什么可能会导致这种情况吗？我注意到我将“销售”设置为帖子类别，当我创建“销售”页面时，它会自动显示来自销售类别的帖子，这是我想要的，但我不确定这是否会有影响吗？

代码位于 custom_functions.php 中。完整代码如下：

function custom_template() {
if (is_page('15030')) : ?>

     elseif (is_page('Sales')){
        <h2>Test Content</h2>
    }

<?php endif; ?>

Answer 1

看起来它需要if 而不是elseif 并像这样包装在php标签中

<?php endif; ?> // this closes the 1st if statement aka the if for is_page('15030').

<?php if ( is_page('Sales') ): ?>
<h2>Test Content</h2>
<?php endif; ?>

Answer 2

根据法典：

由于某些全局变量在循环期间被覆盖，is_page() 将无法工作。为了在循环之后使用它，您必须在循环之后调用 wp_reset_query()。

在我看来，您正在在循环中使用它。
