Question

How can I keep checkboxes selected after the form has been submitted? I found the set_checkbox function in the Codeigniter User Guide, but it doesn’t work.

Form field code from the User Guide

<input type="checkbox" name="mycheck" value="1" <?php echo set_checkbox('mycheck', '1'); ?> />
<input type="checkbox" name="mycheck" value="2" <?php echo set_checkbox('mycheck', '2'); ?> />

I also googled this and found a couple of workarounds, but they were based on previous versions of Codeigniter. And they were based on Form Validation, which isn’t necessary for my form, because none of the fields are required.

How can I retain the checkbox field value after the form is submitted?

UPDATE: This question is not about form validation and errors. I want to retain the checkbox field value AFTER the page is reloaded. Is jquery a possibility?

You can use CI session to store the form data in the session and retrieve it if there are no POST submitted when page get refreshed. So the logic will be

If($this->input->post()){
    /* ...load session class

    ... Fetch form data as u like

    ... Store form data in a session variable */
}else{
   /* ... Load session class 
   ... Check if session variable exist
   ... Load form data from session variable and set the form values */
}
