将textarea数据从视图传递到控制器codeigniter

Question

I have a form in my home_view.php that uses textarea that goes like this:

    <form action="<?php echo base_url();?>add" method="post">
        <textarea name="add-list" id="add-list" rows="10" cols="75"> </textarea>
        <input type="submit" id="add-btn" class="btn btn-primary" value="Add" />
    </form>

In my controller, I have this:

public function add(){
        $value = $this->input->post('add-list');
        echo "<script type='text/javascript'>alert('$value'); window.location.href='".base_url()."'</script>";

        //more code here
}

The problem is the alert only pops up when I have a one-liner input. How can I get all the inputs of the user including new line ('\\n')?

Answer 1

您可以使用nl2br函数：

$value = nl2br($this->input->post('add-list'));
