如何使用textarea插入和显示从codeigniter到数据库的回车键或新行

Question

I'm using a textarea in my html and I also want to store my inputted word on my database by using codeigniter. for example if i entered the word "Hello" and the next line is "World"

like

Hello
World

view

<textarea name=text></textarea>

and before passing it to the controller this is my javascript

function add_work_experience()
{
var P1 = document.getElementById('company');
var P2 = document.getElementById('job_title');
var P3 = document.getElementById('text');
var P4 = document.getElementById('date');
var P5 = document.getElementById('description');


if (P1.value != "" && P2.value != "" && P3.value != "" && P4.value != "" && P5.value != "")
{
    var data = P1.value + "|" + P2.value + "|" + P3.value
    P1.value = "";
    P2.value = "";
    P3.value = "";
    swoosh(data, path+'swoosh_employee/swoosh_work_experience', 'workexperiencedv');

}

controller,, let's say that the variable $P3 is the textarea

parse_str($_SERVER['QUERY_STRING'],$_GET);
    $data = $_GET['h'];
    list($P1,$P2,$P3) = explode("|", $data);
    $this->emp->add_word($P1, $P2, $P3);

model

public function add_word($text)
{
$data = array ('text' => $text);      

$this->db->insert('word', $data);
}

and by displaying it

<?php echo nl2br($text);?>

but it is not working. Is there something that i will do on my mysql server? or in my codeigniter? or in my php? help. i dont know what to do.

尝试使用nl2br将textarea中的新行转换为br标记：

$text = nl2br($this->input->post('text'));
