form_validation with JSON - vertisan - 02-08-2015
Hi!
I'm the beginner with CI and I want to create form with form_validation() and JS.
This is my code:
CONTROLLER:
PHP Code:
...
public function add_wolont()
{
// template...
$this->load->model( 'Wolontariusze' );
if ( !empty( $_POST ) )
{
$this->load->library('form_validation');
$this->form_validation->set_rules('imie_wolont', 'Imie wolontariusza', 'trim|required');
$this->form_validation->set_rules('d_imie_wolont', 'Drugie mie wolontariusza', 'trim|required');
// etc.
if ($this->form_validation->run() === FALSE) {
echo json_encode(array('st' => 0,'msg' => 'ERROR: <br>' . validation_errors()));
} else {
$dodaj_wolont = array(
'imie' => $this->input->post( 'imie_wolont' ),
'drugie_imie' => $this->input->post( 'd_imie_wolont' ),
// etc.
);
$str = "ADDED!";
echo json_encode(array('st' => 1, 'msg' => $str));
}
}
}
VIEW:
Code:
<div id="error"></div>
<?php echo form_open('panel/add_wolont', array('id'=>'dodaj_wolont')) ?>
<label>Imie</label>
<input type="text" name="imie_wolont">
<label>Drugie imie</label>
<input type="text" name="d_imie_wolont">
<label>Nazwisko</label>
<input type="text" name="nazwisko_wolont">
<input type="submit" value="Dodaj">
<?php echo form_close(); ?>JS:
Code:
$(function() {
$('#dodaj_wolont').submit(function() {
$.post($('#dodaj_wolont').attr('action'),$('#dodaj_wolont').serialize(),function(json) {
if ( json.st == 0 ) {
alert(json.msg);
} else {
alert(json.msg);
}
}, 'json');
return false;
});
});In console all is fine, but alerts doesn't work and I don't know why
Can anyone help?
