如何使用PHP隐藏/显示文本内容？

Question

I am confused and not sure why this code is not working.

Here is the original code :

    //start date to end date
    <?php if($show5 < $show6) { ?>

     <a>show content</a>

     <?php }?>

If 'start date' and 'end date' values are empty then I want to remove or hide <?php if($show5 < $show6) { ?> <?php }?> and 'show content'.

And if 'start date' and 'end date' values are not empty then I want to remove or hide <?php if($show5 != '' && $show6 != '') { ?> <?php }?> and show content. If start to end date are not expired and if start to end date are expired then hide the content.

<?php if($show5 != '' && $show6 != '') { ?> 

    //start date to end date
    <?php if($show5 < $show6) { ?>

    <?php } ?>

    <a>show content</a>

    <?php if($show5 != '' && $show6 != '') { ?> 

    <?php } ?>

<?php }?>

Answer 1

is this what you were trying to do?

<?php if ($show5 != '' && $show6 != '') { ?> 
    //start date to end date
    <?php if (strtotime($show5) < strtotime($show6)) { ?>
        <a>show5 content</a> 
    <?php } ?>
    <?php if (strtotime($show5) > strtotime($show6)) { ?>
        <a>show6 content</a> 
    <?php } ?>
<?php } ?>

The bottom code was not necessary and therefore it was throwing an error. Also the html had to be moved few lines top and you were missing one <?php } ?>
