如何在wordpress中不出错地使用if和elseif

Question

我试图在wordpress类别页面中显示基于URL的内容，因此这将帮助我在类别页面上有一些内容，而不仅仅是帖子。

网址：https://www.1govtjob.com

下面的代码运行良好，没有任何问题。

<?php if( $_SERVER['REQUEST_URI'] == '/category/tamilnadu-govt-jobs/' ) { ?>
<p class="top_para">This page is dedicated to Tamilnadu Government Job Alerts.</p>
<?php } ?>

<?php if( $_SERVER['REQUEST_URI'] == '/category/central-govt-jobs/' ) { ?>
<p class="top_para">This page is dedicated to Central Government Job Alerts.</p>
<?php } ?>

我试图使用汇编语言语句，而不是使用多个if语句的每一个类别页。

如果我使用下面的代码，我最终会得到这个错误

<?php if( $_SERVER['REQUEST_URI'] == '/category/tamilnadu-govt-jobs/' ) { ?>
<p class="top_para">This page is dedicated to Tamilnadu Government Job Alerts.</p>
<?php } ?>

<?php elseif( $_SERVER['REQUEST_URI'] == '/category/central-govt-jobs/' ) { ?>
<p class="top_para">This page is dedicated to Central Government Job Alerts.</p>
<?php } ?>

Answer 1

那不管用。在结束的}和之间不应该有结束标记。

试试这个：

<?php if( $_SERVER['REQUEST_URI'] == '/category/tamilnadu-govt-jobs/' ) { ?>
<p class="top_para">This page is dedicated to Tamilnadu Government Job Alerts.</p>

<?php } elseif( $_SERVER['REQUEST_URI'] == '/category/central-govt-jobs/' ) { ?>

<p class="top_para">This page is dedicated to Central Government Job Alerts.</p>
<?php } ?>

Answer 2

不需要一直打开和关闭PHP标记。只需始终呆在PHP中即可。

<?php 
if( $_SERVER['REQUEST_URI'] == '/category/tamilnadu-govt-jobs/' ) {
     echo '<p class="top_para">This page is dedicated to Tamilnadu Government Job Alerts.</p>';
} elseif( $_SERVER['REQUEST_URI'] == '/category/central-govt-jobs/' ) {
     echo '<p class="top_para">This page is dedicated to Central Government Job Alerts.</p>';
}

Answer 3

你可以用这个：

<?php if($condition): ?> <p> html text/code </p> <?php echo "in if"; ?> <?php else: ?> <p> Some html code </p> <!-- or --> <?php echo "in else"; ?> <?php endif;?>
