CodeIgniter 显示数据库中的数据以供查看

Question

我正在尝试从数据库中获取所有数据并传递给视图 我在模型函数中创建用于获取数据，它看起来像这样

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

在视图中，我创建了看起来像这样的 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>

我将数据显示到我的视图中，但经过了 10 次：

有人可以解释我在哪里犯错了吗？

Answer 1

你的h5标签包含$posts，应该是$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

首先我建议你把你的模型代码改成这个

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

那么你的视图会是这样的

<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 } ?>
