单击视图按钮，没有任何反应

After clicking the VIEW button and nothing happening, I started to wonder what's wrong?

GALLERIES NAME  POST    EDIT    DELETE  
Slideshow               VIEW     
SERVICES        POST    VIEW     

Code:

<?php foreach ($gallery as $gallery_item): ?>
    <tr>
        <td><?php echo $gallery_item['galleries_name']; ?></td>
        <td>
            <?php if( $gallery_item['galleries_post_type'] == 'post') { echo "#"; }?>   
        </td>
        <td>
            <button type="button" class="edit" onclick="location.href = '
                <?php 
                if( $gallery_item['galleries_post_type'] == 'post') {
                    echo site_url('cpages/galleries/'.$gallery_item['galleries_id']); 
                } else {                                
                    echo site_url('cpages/viewpictures/'.$gallery_item['galleries_id']); 
                }
                ?>
            ';">VIEW</button>
        </td>

I think you should use links and describe them as button (role, type, whatsoever) and decore them with CSS. That is:

<?php

$id = $gallery_item['galleries_id']);

?>

<td>
    <?php if ($gallery_item['galleries_post_type'] === 'post'): ?>
        <a href="<?= site_url('cpages/galleries/'.$id); ?>" class="edit">
    <?php elseif (): ?>
        <a href="<?= site_url('cpages/viewpictures/'.$id); ?>" class="edit">
    <?php endif; ?>
</td>

By searching for a better solution, I found an answer from BalusC that, I think, should solve your problem and help you understand how/what/when questions about buttons, links and so one.
