这种形式（codeigniter）不起作用

Question

I don't seem to be able to make a simple form work in codeigniter..

the following code:

$this->load->helper('form');
echo form_open('welcome/test_form');
echo form_button('button_name', 'click!');
echo form_close();

produces the following HTML:

<form action="http://localhost:8888/index.php/welcome/test_form" method="post" accept-charset="utf-8">
<button name="button_name" type="button" >click!</button>
</form>

Yet when i click on the button nothing happens, the page stays the same.

Any ideas?

You're not creating a submit button. You need to use something like this:

$this->load->helper('form');
echo form_open('welcome/test_form');
echo form_submit('button_name', 'click!');
echo form_close();

docs here:

the button element is not the same as a submit button. It won't submit your form.
