Question

站点/视图/ index.php的

<?php foreach($pic as $pic_item): ?> { 
                            <img src="<?php echo base_url('assets1/images/slider/'.$pic_item->pic_item );?>">                   
                    } 
                    <?php endforeach;
                    ?>

控制器/ Cspages.php

    public function index()
{


    $this->load->model('gallery_model');

    $pic_unique_id = 18;  // slider

    $data['pic'] = $this->gallery_model->get_picture($pic_unique_id);

    $this->load->view('index', $data);
}

模型/ Gallery_model.php

public function get_picture($pic_unique_id)
{

    $query = $this->db->get_where('galleries_pictures', array('picture_unique_id' => $pic_unique_id));
    return $query->result();

}

Answer 1

在视图中更改您的foreach循环，如下所示：

<?php foreach($pic as $pic_item): ?>     
<img src="<?php echo base_url('assets1/images/slider/').$pic_item->pic_item;?>">               
<?php endforeach;?>

OR

<?php foreach($pic as $pic_item): ?> 
    <img src="<?php echo base_url('assets1/images/slider/'.$pic_item->pic_item );?>">                   
<?php endforeach;?>

<强>更新

模型

<?php
    public function get_picture($pic_unique_id)
    {

        $this->db->where('picture_unique_id',$pic_unique_id);
        $query = $this->db->get_where('galleries_pictures');
        return $query->row;

    }

控制器

public function index()
{

    $this->load->helper('url');//load url helper
    $this->load->model('gallery_model');

    $pic_unique_id = 18;  // slider

    $data['pic'] = $this->gallery_model->get_picture($pic_unique_id);

    $this->load->view('index', $data);
}

视图

<img src="<?php echo base_url('assets1/images/slider/'.$pic->pic_item );?>">

为什么这个错误出现stdClass :: $ pic_item？
