Php 试图获取子类别中非对象产品详细信息的属性

我想显示所选子类别的一个产品，但出现错误

消息：试图在查看产品详细信息时获取非对象属性
，如果控制器、模型和视图中存在错误，请更正

我的错在哪里

看法

控制器

public function detail($product_id){
     $data=array('title'   =>'Pasar Online | Detail Produk',
           'username'      => $this->session->userdata('username'),
           'categories'    => $this->categories_model->get_categories(),
           'details'       => $this->categories_model->get_details($product_id),
           'isi'           =>'member/detail');
     $this->load->view('template_home/wrapper',$data);
 }

打印（类别）

打印（详细信息）

故障在循环中
$details
尝试以下操作…查看：

<?php foreach ($categories as $key=>$value) { ?>
      <div class="col-sm-3">
           <h5><?php echo $categories[$key]->categoriesName; ?></h5>
           <?php if(count($categories[$key]->subs)>0) { ?>
           <?php foreach ($categories[$key]->subs as $k=>$v)  { ?>
                 <ul>
                     <li><a href="<?php echo base_url();?>member/detail">
                         <?php echo $v->productName; ?></a></li>
                 </ul>
            <?php } ?>
            <?php } ?>
      </div>
 <?php } ?>

<div class="row" id="productMain">
    <div class="col-sm-4">
        <div id="mainImage"><img src="<?php echo base_url('upload/'.$details->photo);?>"
         alt="" class="img-responsive">div>
    </div>
<?php if(count($details)>0){
    <div class="col-sm-4">
        <div class="box">
            <h1 class="text-center"><?php echo $details->productName;?></h1>
            <p class="price">
                <?php echo $details->price;?>
            </p>
        </div>
    </div>
<?php } ?>
</div>

print\r（$categories）
上的输出是什么？我已经编辑了，所以循环中没有人，但当我选择显示的“产品详细信息”时，您必须传递id。请尝试您可以做的。这仍然是错误的，试图在viewtry edited answer中获取“$detail”中非对象的属性时出现错误消息。您的数组为空。只需计算数组。我已经编辑了产品详细信息，但仍然没有结果显示，我插入了打印，但其结果类似于此“数组（）1”将id发送到您模型的details函数，它只是一个可以显示的产品，而我希望能够在选中时显示其他产品
