数组在控制器中正确打印,但未在视图页面中打印
Array printed correctly in controller,but not printed in the view page
print_r($listb)
在控制器中正常工作。但是当我们将这个数组传递给查看页面时,它在查看页面中不起作用。控制器和视图页面以及模型功能如下:
控制器
public function index() {
$this->load->helper('url');
$this->load->view('user/templates/header');
$data['banner'] = $this->banner_model->viewbanner();
$this->load->view('user/templates/sidebar', $data);
$data1['list1'] = $this->featured_model->viewfeaturedlist(1);
$listb = array();
foreach ($data1['list1'] as $list1) {
$list = explode(',', $list1->fet_list);
$type = $list1->fet_type;
foreach ($list as $pid) {
if ($type == 1) {
$listb['hhh'] = $this->featured_model->viewb2bproduct($pid);
//print_r($listb);
}
}
}
$this->load->view('user/templates/featured', $listb);
exit;
$this->load->view('user/templates/footer');
}
}`enter code here`
查看
<?php
print_r($hhh);
?>
型号
public function viewb2bproduct($id) {
$this->db->select('*');
$this->db->from('jil_products');
$this->db->where('prd_id', $id);
$query = $this->db->get();
return $query->result();
}
您的 $listb['hhh']
在 foreach 循环中,您每次都在为 $list
的每个元素覆盖它。在控制器中,您在 foreach
循环中打印它,这就是为什么它提供输出但不在您的 view
.
中的原因
模型中
public function viewb2bproduct($id) {
$this->db->select('*');
$this->db->from('jil_products');
$this->db->where('prd_id', $id);
$query = $this->db->get();
$result = $query->result_array();
return $result;
}
在控制器中
public function index()
{
$this->load->helper('url');
$data['banner'] = $this->banner_model->viewbanner();
$data1['list1'] = $this->featured_model->viewfeaturedlist(1);
$this->load->view('user/templates/sidebar', $data);
$this->load->view('user/templates/header');
$this->load->view('user/templates/featured', $listb);
$this->load->view('user/templates/footer');
}
}
和可见
<?php
foreach ($list1 as $new_list1)
{
echo "<p>".$new_list1['table_field']."</p>"
}
我对这部分一无所知
$listb = array();
foreach ($data1['list1'] as $list1)
{
$list = explode(',', $list1->fet_list);
$type = $list1->fet_type;
foreach ($list as $pid) {
if ($type == 1) {
$listb['hhh'] = $this->featured_model->viewb2bproduct($pid);
//print_r($listb);
}
}
}
在您的控制器中更改此行:
$listb['hhh'] = $this->featured_model->viewb2bproduct($pid);
到
$listb['hhh'][] = $this->featured_model->viewb2bproduct($pid);
在视图中:
<?php
foreach ($fff as $product){
echo $products[0]['prd_id']."<br>";
echo $products[0]['prd_name']."<br>"; //and so on
}
$hhh=array();
foreach ($data1['list1'] as $list1) {
$list = explode(',', $list1->fet_list);
$type = $list1->fet_type;
foreach ($list as $pid) {
if ($type == 1) {
$hhh[] = $this->featured_model->viewb2bproduct($pid);
//print_r($listb);
}
}
}
$listb['hhh']=$hhh;
$this->load->view('user/templates/featured', $listb);
