如何在Codeigniter中设置character_limiter（） [英] How To Set character_limiter() in Codeigniter

问题描述

我是Codeigniter的新手。现在，我想在视图中设置字符数限制。首先，使用$ query_result-> result（）从数据库中获取数据，然后使用foreach（）在视图中显示它。

I'm new to Codeigniter. Now I want to set the character limit in the view. First, get the data from the database with $query_result->result(), and then show it in the view using foreach().

这是我的控制器，模型和视图：

Here is my Controller, Model and View:

public function index() {
$data = array();
$data['category'] = $this->product_model->selectAllcategory();
$data['randProduct'] = $this->product_model->selectRandomProduct();
$data['products'] = $this->product_model->selectAllProduct();
$data['maincontent'] = $this->load->view('home', $data, true);
$data['title'] = 'Welcome Russel Store';
$this->load->view('index', $data);
}

我的模型：

public function selectAllProduct() {
$this->db->select('*');
$this->db->from('product');
$this->db->where('status', 1);
$this->db->order_by('product_id', 'desc');
$query_result = $this->db->get();
$result = $query_result->result();
return $result;
}

我想在视图中设置字符限制：

And I want to set the character limit in the View:

echo character_limiter($result->product_title, 25); 

推荐答案

您应在控制器中导入 Text Helper

，在构造函数中加载帮助器，模型和库是一个好习惯

function __construct()
{
  parent::__construct();
  $this->load->helper('text');
  $this->load->model('products_model'); //name of your model class

}

function index()
{
  $data['products']=$this->products_model->selectAllProduct();
  $this->load->view('index',$data);
}

在您看来index.php

at your view index.php

//This is an example from CI's home page        
//$string = "Here is a nice text string consisting of eleven words.";            
//$string = word_limiter($string, 4);

    foreach($products as $p)
    {
        $limited_word = word_limiter($p[product_title],25);
        echo $limited_word;
    }
