PHP else/if statements

本文关键字：statements if else PHP | 更新日期: 2023-09-27

我已经写了下面的PHP语句，但每次我尝试将其组合成else/if时，它都会中断。

有人可以建议吗？我是PHP的新手，有点卡住了。

谢谢:)

<?php if (is_page( 19 ) ) {?>
<div class="imageSlider"><img src="<?php echo bloginfo('template_directory');?>/Images/mainImages/innerPage-Image.jpg" alt="" /><img src="<?php echo bloginfo('template_directory');?>/Images/mainImages/innerPage-Image2.jpg" alt="" /><img src="<?php echo bloginfo('template_directory');?>/Images/mainImages/innerPage-Image3.jpg" alt="" /></div>
<?php }?>
<?php if (is_page( 23 ) ) {?>
<div class="imageSlider"><img src="<?php echo bloginfo('template_directory');?>/Images/mainImages/innerPage-Image.jpg" alt="" /><img src="<?php echo bloginfo('template_directory');?>/Images/mainImages/innerPage-Image.jpg" alt="" /><img src="<?php echo bloginfo('template_directory');?>/Images/mainImages/innerPage-Image.jpg" alt="" /></div>
}
<?php }?>

使用以下语法：

<?php if (condtion):?> 
 // html goes here,
<?php elseif(condtion): ?>
 // html goes here,
<?php endif; ?>

<?php if (is_page( 19 ) ) {?> 
<div class="imageSlider"><img src="<?php echo bloginfo('template_directory');?>/Images/mainImages/innerPage-Image.jpg" alt="" /><img src="<?php echo bloginfo('template_directory');?>/Images/mainImages/innerPage-Image2.jpg" alt="" /><img src="<?php echo bloginfo('template_directory');?>/Images/mainImages/innerPage-Image3.jpg" alt="" /></div> 
<?php } elseif (is_page( 23 ) ) {?> 
<div class="imageSlider"><img src="<?php echo bloginfo('template_directory');?>/Images/mainImages/innerPage-Image.jpg" alt="" /><img src="<?php echo bloginfo('template_directory');?>/Images/mainImages/innerPage-Image.jpg" alt="" /><img src="<?php echo bloginfo('template_directory');?>/Images/mainImages/innerPage-Image.jpg" alt="" /></div>
<?php }?>

下面是一个示例，如果/否则使用您的代码

<?php if (is_page(19)) { ?>
    //Insert html
<? { elseif (is_page(23)) } ?>
   //Insert other html
<? } ?>
