我是在我的项目中使用代码点火器的新用户,我在上传多个文件时面临一个问题,但最后一个只插入到所有图像三个图像字段.
我的控制器是:
function products()
{
date_default_timezone_set("Asia/Kolkata");
$config['upload_path'] = './resources/images/products/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = 1000;
$config['max_width'] = 1024;
$config['max_height'] = 768;
$this->load->library('upload', $config);
$this->upload->do_upload('userfile');
$data = array('prod_image' => $this->upload->data(),
'prod_image1' => $this->upload->data(),
'prod_image2' => $this->upload->data());
$product_image=$data['prod_image']['file_name'];
$product_image1=$data['prod_image1']['file_name'];
$product_image2=$data['prod_image2']['file_name'];
$data = array(
'name' => $this->input->post('pd_name'),
'prod_image' => $product_image,
'prod_image1' => $product_image1,
'prod_image2' => $product_image2,
'created_time' => date('Y-m-d H:i:s'));
// insert form data into database
$result_set= $this->tbl_products_model->insertUser($data);

我的观点部分是:
<input class="form-control" name="pd_name"type="text"/>
<input type="file" class="file_upload2" name="userfile"/> //1
<input type="file" class="file_upload2" name="userfile"/> //2 …Run Code Online (Sandbox Code Playgroud) 我想加密一个电子邮件 ID 并解密它如何?我检查了文档,但它只显示密码加密,并且显示的是真或假的结果。

我想计算所有可能的子集形式数组的总和。
$array= Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 [4] => 6 ); //changing
function powerSet($array) {
// add the empty set
$results = array(array());
foreach ($array as $element) {
foreach ($results as $combination) {
$results[] = array_merge(array($element), $combination);
$total= array_sum($results); // I try this
}
echo $total; // I try this
}
return $results;
}

上面的代码用于查找子集。我从这里找到了这段代码。我只添加array_sum但显示0的方式如何找到每个子集的总和?有什么办法吗?
