Php if else 和 html

Question

对于弄清楚为什么我在下面的代码中在线获得“其他”(T_ELSE) 有什么帮助吗？

 <?php if ( is_category( '3' ) )  ?>
        <td class="logo-alts"><a href="/"><img src="<?php bloginfo('template_directory'); ?>/_images/image1.png"></a></td>

  <?php if ( is_category( '1096' ) )  ?>
        <td class="logo-alts"><a href="/"><img src="<?php bloginfo('template_directory'); ?>/_images/image2.png"></a></td>

  <?php if ( is_category( '1437' ) )  ?>
        <td class="logo-alts"><a href="/"><img src="<?php bloginfo('template_directory'); ?>/_images/image3.png"></a></td>

  <?php if ( is_category( '1150' ) )  ?>
        <td class="logo-alts"><a href="/"><img src="<?php bloginfo('template_directory'); ?>/_images/image4.png"></a></td>

  <?php if ( is_category( '1138' ) )  ?>
        <td class="logo-alts"><a href="/"><img src="<?php bloginfo('template_directory'); ?>/_images/image.png"></a></td>

  <?php if ( is_category( '3' ) )  ?>
        <td class="logo-alts"><a href="/"><img src="<?php bloginfo('template_directory'); ?>/_images/image5.png"></a></td>

  <?php else : ?>
        <td class="logo-alts"><a href="/"><img src="<?php bloginfo('template_directory'); ?>/_images/image6.png"></a></td>
    <?php endif; ?>

像这样格式化你的 IF 语句:

      <?php if (is_category('3')) : ?>
            <td class="logo-alts"><a href="/"><img src="<?php bloginfo('template_directory'); ?>/_images/image.png"></a></td>

      <?php elseif (is_category('1096')) : ?>
            <td class="logo-alts"><a href="/"><img src="<?php bloginfo('template_directory'); ?>/_images/image.png"></a></td>

      <?php elseif (is_category('1437')) : ?>
            <td class="logo-alts"><a href="/"><img src="<?php bloginfo('template_directory'); ?>/_images/image.png"></a></td>

      <?php elseif (is_category('1150')) : ?>
            <td class="logo-alts"><a href="/"><img src="<?php bloginfo('template_directory'); ?>/_images/image.png"></a></td>

      <?php elseif (is_category('1138')) : ?>
            <td class="logo-alts"><a href="/"><img src="<?php bloginfo('template_directory'); ?>/_images/image.png"></a></td>

      <?php elseif (is_category('3')) : ?>
            <td class="logo-alts"><a href="/"><img src="<?php bloginfo('template_directory'); ?>/_images/image.png"></a></td>

      <?php else : ?>
            <td class="logo-alts"><a href="/"><img src="<?php bloginfo('template_directory'); ?>/_images/image.png"></a></td>
        <?php endif; ?>
