本文实例讲述了CI映射(加载)数据到view层的方法。分享给大家供大家参考,具体如下:
CI有个恶心的东西,就是需要把所有的数据都要放到$data数组中才能映射到view层,如:
当前我从数据库的link表(友情链接表,字段:id name url),搜索出来的数据方式:
$query = $this->db->query("select id,name,url from cg_link where 1"); $links = $query->result(); //这里的$links是不能直接传输入view层的.对错比较 //错误的传输(映射方式): //$this->load->view('link',$links); //正确的传输(映射方式): $data['links'] = $links; $this->load->view('link',$data);
所以只要是数据传输都必须放到$data数据中,如果要查询一条数据或一维数组则使用如下函数
$sql = "select id,name,url from cg_link where id=21 limit 1"; $query = $this->db->query($sql); $one = $query->row();//这里是一条数据,获取方式,$one->name;

The best ways to send emails using PHP include: 1. Use PHP's mail() function to basic sending; 2. Use PHPMailer library to send more complex HTML mail; 3. Use transactional mail services such as SendGrid to improve reliability and analysis capabilities. With these methods, you can ensure that emails not only reach the inbox, but also attract recipients.

Calculating the total number of elements in a PHP multidimensional array can be done using recursive or iterative methods. 1. The recursive method counts by traversing the array and recursively processing nested arrays. 2. The iterative method uses the stack to simulate recursion to avoid depth problems. 3. The array_walk_recursive function can also be implemented, but it requires manual counting.

In PHP, the characteristic of a do-while loop is to ensure that the loop body is executed at least once, and then decide whether to continue the loop based on the conditions. 1) It executes the loop body before conditional checking, suitable for scenarios where operations need to be performed at least once, such as user input verification and menu systems. 2) However, the syntax of the do-while loop can cause confusion among newbies and may add unnecessary performance overhead.

Efficient hashing strings in PHP can use the following methods: 1. Use the md5 function for fast hashing, but is not suitable for password storage. 2. Use the sha256 function to improve security. 3. Use the password_hash function to process passwords to provide the highest security and convenience.
