form_radio() validation problem - El Forum - 10-04-2011
[eluser]Unknown[/eluser]
I want to achieve 2 things with the radio buttons:
1) I want to know how to do validation for radio buttons.
2) Upon validation error, how to auto-select the last selected radio button.
Below is the code I have. I know I haven't done it correctly. If someone could guide me to the right direction, that'll be great. Thanks
In my view:
Code:
$form_data['radio1'] = array(
'name' => 'radio_select',
'id' => 'radio1',
'value' => 'radio1',
'style' => 'margin-bottom:12px; margin-right:4px;',
'checked' => set_value('true', isset($radio_select['radio1']['checked'])?TRUE:FALSE)
);
$form_data['radio2'] = array(
'name' => 'radio_select',
'id' => 'radio2',
'value' => 'radio2',
'style' => 'margin-bottom:12px; margin-right:4px;',
'checked' => set_value('false', isset($radio_select['radio2']['checked'])?TRUE:FALSE)
);
echo form_radio($form_data['radio1']); echo "Radio 1";
echo form_radio($form_data['radio2']); echo "Radio 2";In my controller:
Code:
$this->form_validation->set_rules('radio_select', 'Radio button', 'required');
