我为单品上传了多张图片。这里的情况是我有products table和product_images表。这两个表是有关系的。 product_images表的product_id列是产品表的product_id列的外键。以下是详细代码。Code 现在我已经尝试过这种方式来访问图像。 在我的模型中,获取功能是:
public function get_product()
{
#code
$query=$this->db->get('products');
return $query->result_array();
}
我的观点是:
div class="container">
<h2>Product Lists</h2>
<table class="table table-striped, table-hover">
<thead>
<tr>
<td><strong>Product_Id</strong></td>
<td><strong>Product_Name</strong></td>
<td><strong>Picture</strong></td>
<td><strong>Options</strong></td>
</tr>
</thead>
<tbody>
<?php foreach ($products as $p): ?>
<tr>
<td><?php echo $p['product_id']; ?></td>
<td><?php echo $p['product_name']; ?></td>
<!-- <td><?php echo $p['picture']; ?> </td> -->
<td><img src="<?php echo base_url('uploads/images/').$images[0];?>" /> </td>
<td>
<a href="<?php echo site_url('#'); ?>">View</a>
</td>
</tr>
<?php endforeach; ?>
</tbody>
</table>
除了没有显示图像外,一切正常。它只是显示图像的裂缝缩略图。
这是我的存储功能:
public function set_product($id=0){
$picture=array();
$count=count($_FILES['picture']['name']);
//Check whether user upload picture
if(!empty($_FILES['picture']['name'])){
foreach($_FILES as $value){
for($s=0; $s<=$count-1; $s++){
$_FILES['picture']['name']=$value['name'][$s];
$_FILES['picture']['type'] = $value['type'][$s];
$_FILES['picture']['tmp_name'] = $value['tmp_name'][$s];
$_FILES['picture']['error'] = $value['error'][$s];
$_FILES['picture']['size'] = $value['size'][$s];
$config['upload_path'] = 'uploads/images/';
$config['allowed_types'] = 'jpg|jpeg|png|gif';
$config['file_name'] = $_FILES['picture']['name'];
//Load upload library and initialize configuration
$this->load->library('upload',$config);
$this->upload->initialize($config);
// print_r($value['name'][$s]);exit;
if($this->upload->do_upload('picture')){
$uploadData = $this->upload->data();
$picture[] = $uploadData['file_name'];
}
}
}
}//end of first if
$data=array('product_name'=>$this->input->post('product_name'));
if ($id==0){
$this->db->insert('products',$data);
$last_id = $this->db->insert_id();
if(!empty($picture)){
foreach($picture as $p_index=>$p_value) {
$this->db->insert('images', array('product_id'=>$last_id,'images'=>$p_value));
}
}
}
else {
$this->db->where('id',$id);
$this->db->update('products',$data);
if(!empty($picture)){
foreach($picture as $p_index=>$p_value) {
$this->db->update('images', array('product_id'=>$last_id,'images'=>$p_value) ); // --> this one?
}
}
}
}
