笨显示数据，查看

Question

我试图从数据库中获得的所有数据，并通过查看 我在模型函数创建获取数据，而且它看起来像

public function get_data_from_db(){ 
     $query = $this->db->get('posts'); 
     return $query->result_array(); 
    } 

，并鉴于我创建它看起来像foreach循环：

<h6>Mjesto Odredista: 
<?php if($posts): ?> 
<?php foreach ($posts as $post): ?> 
<div class="well"> 
<h5><?php echo $posts['mjestoOdredista'];?> 
</div> 
<?php endforeach;?> 
     <?php else : ?> 
<?php endif;?> 
</h6> 

，我得到的数据，以我的看法，但经过10时间：

有人可以解释我犯了什么错误？

Answer 1

你的h5标签包含$ posts，它应该是$ post。

<h6>Mjesto Odredista: 
<?php if($posts): ?> 
<?php foreach ($posts as $post): ?> 
<div class="well"> 
<h5><?php echo $post['mjestoOdredista'];?> 
</div> 
<?php endforeach;?> 
     <?php else : ?> 
<?php endif;?> 
</h6> 

Answer 2

首先，我建议你改变你的模型代码这个

public function get_data_from_db(){ 
    //less lines of code, and using result() makes your loop easier 
    return $this->db->get('posts')->result(); 
} 

那么您认为会是这样

<h6>Mjesto Odredista: 
<?php if($posts){ 
    foreach ($posts as $post): ?> 

     <div class="well"> 
      <!--$post is an object, so u use the arrow to display it, instead of the [] for arrays 
      note that this only works if mjestoOdredista is a column name from your database, if not, use the column name to display the value --> 
      <h5><?=$post->mjestoOdredista?></h5> 
     </div> 

    <?php endforeach; 

}else { ?> 

    //do something else 

<?php } ?>
