I have a form that will store three items into an array.
I want to check those items and make sure all three are different values, if there is a match, I want to return FALSE;
example array:
Code:
$fruit = array('apple', 'orange', 'apple');
// compare each item in array, if match is found, return TRUE
return FALSE;
$fruit = array('apple', 'orange', 'banana');
// compare each item in array, if no match is found, return FALSE
return TRUE;
I am not sure how I would check each item in the array - any help is appreciated, thanks.
UPDATE: created three different drop-down fields, and just did a conditional, not sure if that is the most efficient way to accomplish it.
I don't need it to be in an array, I would actually prefer it being in 3 separate drop-downs.
Code:
// form submitted and validated continue processing
if($this->input->post('register') && $this->form_validation->run()) {
// if user selects the same venue twice, let them know
if(
( $this->input->post('venue_1') == $this->input->post('venue_2') )
||
( $this->input->post('venue_1') == $this->input->post('venue_3') )
||
( $this->input->post('venue_2') == $this->input->post('venue_3') )
) {
$data['duplicate_venue_error'] = "Each preference needs to be different";
$this->load->view('register/registration-form-view', $data);
} else {
// each venue was different, proceed
// form validated and worked, go insert volunteer info into data table
$this->register_model->insertVolunteer();
}
} else {
$data['duplicate_venue_error'] = NULL; // pass null to shut up undefined variable msg in view
$this->load->view('register/registration-form-view', $data);
}
