Re-populating Array Check Boxes after Validation Failure - El Forum - 05-17-2008
[eluser]gkchicago[/eluser]
I had trouble getting my array checkboxes to re-populate after a failed validation and have gotten it to work how I wanted without modifying the validation or input libraries so I thought I would share it here. I appreciate any input or opinions to help clean this up before I possibly make it a wiki entry.
Important Note: I am not doing any validation on the checkbox itself, the checkboxes for my needs are considered optional in the context of the form.
Methodology:
A simple in_array check is used in the view to set the 'checked' (TRUE/FALSE) flag that is used by the form_checkbox function when outputting the checkboxes. Because my checkboxes have numeric ids a loop is used to keep the code relatively clean but is not required. The controller must pass the POST-ed array data back to the view on validation failure.
View:
Code:
# Checkbox ids, probably loaded from a database
$checkboxes = array('1','2','7');
foreach ( $checkboxes as $checkbox )
{
if ( isset($active_checkboxes) && in_array($checkbox, $active_checkboxes) ) $checkbox_status = TRUE; else $checkbox_status = FALSE;
echo '<p>'.'Item '.$checkbox.' '.form_checkbox($data = array('name' => 'active_checkboxes[]', 'id' => 'active_checkbox'.$checkbox, 'value' => $checkbox, 'checked' => $checkbox_status)).'</p>';
}active_checkboxes is set in the controller on validation failure.
Controller:
Code:
function add()
{
$this->load->library('validation');
$rules['somefield'] = "required";
$this->validation->set_rules($rules);
$fields['somefield'] = "Some Field";
$this->validation->set_fields($fields);
if ($this->validation->run() == FALSE)
{
$data = array();
if ( $this->input->post('active_checkboxes') ) $data['active_checkboxes'] = $this->input->post('active_checkboxes');
$this->load->view('sandbox');
}
else
{
echo "success";
print_r($_POST['active_checkboxes']);
}
}Because the checkboxes are outside the validation in the controller we need to check the post variables and set active_checkboxes for the reloaded view.

Hi
CI not dealing properly with user submitted array values through forms. To deal with that have a look at the below thread:

Hi vadivelan, I had run across your post while I was looking for the solution to this problem but I resisted using it because I didn't want to extend the code igniter validation library. But it looks like they are looking for something like your code for bug http://codeigniter.com/bug_tracker/bug/4530/
