I have a tiny CI form, like following:
<div class="box_txt">
<?php $attributes = array('clock_id' => $clock['id']); ?>
<?php echo form_open('clock/start', $attributes) ?>
<input type="submit" value="Start" />
</form>
</div>
And it generates a from with the folowing openning:
<form action="../clock/start" clock_id="123" method="post" accept-charset="utf-8">
I would really need to know what's the correct way to capture the clock_id in controller's function?
Instead of putting clock_id as a form attribute, you should consider using a hidden input tag:
<input type='hidden' name='clock_id' value='<?php echo $clock["id"]; ?>'/>
then you can handle it using $this->input->post('clock_id')
Otherwise, if you really want to stick to your code, you could use jquery to get the attribute and send an ajax request:
var clock_id = $('form').attr('clock_id');
$('form').submit(function(e){
e.preventDefault();
var url = $(this).attr('action');
var type = $(this).attr('method');
var data = $(this).serialize() + '&clock_id=' + clock_id
$.ajax({
url: url,
type: type,
data: data,
success:function(response){ /* handle response */}
});
});
The clock_id value on the form tag won't be sent with a form submit, as it's not a form element. Instead, you should do the following to use a hidden field:
echo form_hidden('clock_id', $clock['id']);
That will create a hidden field within your form, with the name 'clock_id' and the value, in this case, '123'
If you need clock_id in controller,try this code.
<div class="box_txt">
<?php echo form_open('clock/start') ?>
<input type="hidden" name="clock_id" value="123" />
<input type="submit" value="Start" />
<?php echo form_close() ?>
</div>
Controller:
function start()
{
$clock_id = $this->input->post('clock_id');
}
