对我来说这是新的,有点超出我的深度。好的,所以我试图引入一些数据,我得到一些错误,我有点困惑,到底是怎么回事。
这是型号代码:
public function get_webstore_sets($limit, $offset) {
$this->db->select("*");
$this->db->from('st_posts');
$this->db->where("type", "webstore");
$this->db->limit($limit, $offset);
$this->db->order_by('created', 'DESC');
$query = $this->db->get();
$data = $query->result_array();
return$data;
}
public function count_webstore_sets() {
$this->db->select("*");
$this->db->from('st_posts');
$this->db->where("type", "webstore");
$this->db->order_by('created', 'DESC');
$query = $this->db->get();
$count = $query->num_rows();
return $count;
}
以下是我在控制器中尝试的内容:
class Webstore extends MY_Controller {
public function __construct() {
parent::__construct();
$this->load->model("post");
$this->load->database();
$this->load->helper("url");
}
public function index() {
$this->data['posts'] = $this->post->get_webstore_sets($limit=null, $offset=null); // calling Post model method getPosts()
$data = array('page_title' => 'Store', 'video_content');
$this->layout("pages/webstore", $data);
}
}
然后将其引入HTML:
<?php foreach ($posts as $webstore): ?>
<div class="col-md-12" style="height: 225px;">
<div class="col-md-3">
<?php
$webstore['images'] = explode(".", $webstore['images']);
?>
<img class="thumbnail" width="250px" src="<?php echo $video['images'][1]; ?>.gif"/>
</div>
<div class="col-md-5">
<h3><?php echo $webstore['title']; ?></h3>
</div>
<div class="col-md-4 text-center">
Date Added: <?php echo date('d-m-y', strtotime($webstore['created'])) ?>

<?php endforeach; ?>
我知道连接正常,因为该网站正在从其他地方引入数据。
这是我得到的错误:
Severity: Notice
Message: Undefined variable: posts
Filename: pages/webstore.php
Line Number: 39
A PHP Error was encountered
Severity: Warning
Message: Invalid argument supplied for foreach()
Filename: pages/webstore.php
Line Number: 39
我已将空白文件路径以防万一;)编辑上述错误
答案 0 :(得分:2)
在此代码中:
public function index()
{
$this->data['posts'] = $this->post->get_webstore_sets($limit=null, $offset=null); // calling Post model method getPosts()
$data = array('page_title' => 'Store', 'video_content');
$this->layout("pages/webstore", $data);
}
您要传递$data
数组进行查看,而不是$this->data
数组。此外,'video_content'
数组的$data
元素应该具有让您在视图中接近它的关键。或者它本身缺少价值?
将其更改为:
public function index() {
$this->data['posts'] = $this->post->get_webstore_sets($limit=null, $offset=null); // calling Post model method getPosts()
$this->data['page_title'] = 'Store';
$this->layout("pages/webstore", $this->data);
}
现在,您应该能够在视图文件中获取$posts
变量。只需检查您要对值/键'video_content'执行的操作。

您在没有参数的情况下调用get_webstore_sets()
,因此要么填写一些参数(限制,偏移),要么按如下方式定义函数:
public function get_webstore_sets($limit=null, $offset=null) ...
我建议在类index()
的函数Webstore
中给出参数。
