从POST CodeIgniter检索数据数组

Question

I'm using CodeIgniter and I'm having trouble retrieving an array from the input. I have been searching but I can't solve this. The thing is i'm using a button to dynamically add text boxes.

(HTML from view.php)

<?php echo form_open('verifynovareceita'); ?>
(...)
<div id="ings">
       <p>Ingredients:</p>
       <input type="text" name="ings[]"/>
</div>

<input type="button" value="Add another ingrdient" name="add" onClick="addTextBox()">

(...)

<script type='text/javascript'>
    function addTextBox() {
        var ings = document.getElementById("ings");
        var input1 = document.createElement("input");
        input1.type = "text";       
        input1.name = "ings[]";
        ings.appendChild(input1);
    }

And the (visual) result is what it's expected. It creates as many inputs as I wanted. The problem is when it comes to retrieving the data from the POST array:

(PHP from controller)

  $ings = $this->input->post('ings');
  $row_count = count($ings);

$row_count has value 1, no matter how many text boxes existed. Is there a problem with my code? Or is it the fact that i'm using form_open that makes it impossible to work? I've tried to do the same thing, without codeigniter and it worked fine... I appreciate any help! Thank you in advance.

Answer 1

$this->input->post() function will not work up to mark if input is such type of array. if input is a such type of array you should use classic mehtod

$ings = $_POST('ings'); $row_count = count($ings);
