I'm writing a system where users can generate/run queries on demand based on the values of 4 dropdown lists. The lists are dynamically generated based on a number of factors, but at this point, I'm having problems validating the input using codeigniter's built in validation classes. I think I have things out of order, and I've tried looking at the codeigniter site, but I think I'm tripping myself up.
in my view(/dashboard/dashboard_index.php), I have the following code block:
<?=form_open('dashboard/dashboard_add');?>
<select ... name='selMetric'>
<select ... name='selPeriod'>
<select ... name='selSpan'>
<select ... name='selTactic'>
<input type="submit" name="submit_new_query" value="Add New Graph" class="minbutton" ></input>
<?=form_close();?>
Then in my controller, I have the following 2 methods:
function index() {
$this->load->helper(array('form', 'url'));
$this->load->library('validation');
//population of $data
$this->load->tile('dashboard/dashboard_index', $data);
}
function dashboard_add()
{
$rules['selMetric'] = "callback_sel_check";
$rules['selPeriod'] = "callback_sel_check";
$rules['selSpan'] = "callback_sel_check";
$rules['selTactic'] = "callback_sel_check";
$this->validation->set_rules($rules);
$fields['selMetric'] = "Metric";
$fields['selPeriod'] = "Time Period";
$fields['selSpan'] = "Time Span";
$fields['selTactic'] = "Tactic";
$this->validation->set_fields($fields);
if ($this->validation->run() == false) {
$this->index();
}
else {
//do stuff with validation information
}
}
Here's my issue. I can get the stuff to validate correctly, but for the number of errors I have, I get
Unable to access an error message corresponding to your field name.
as the error message for everything. I think my issue that I have the $rules and $fields stuff in the wrong place, but I've tried a few permutations and I just keep getting it wrong. I was hoping I could get some advice on the correct place to put things.
