Retaining State of Radio Buttons and Checkboxes - CodeIgniter 3

PHP
1

I am finding the documentation and examples that I’ve Googled about this topic confusing. I can’t figure out the proper way to use set_radio() and set_checkbox to keep the values of radio buttons and checkboxes after form submission. Here is a portion of my form:

<div class="form-control">
     Client has read and understood the confidentiality guidelines.
     <?php 
         $data = array(
             'name'  => 'guidelines',
             'id' => 'signed_yes',
             'value' => 'yes',
             'style' => 'margin-left: 20px;'
             );
        echo form_radio($data); 
   ?>
   <?php echo form_label('Yes', 'signed_yes'); ?>
   <?php 
        $data = array(
             'name'  => 'guidelines',
             'id' => 'signed_no',
             'value' => 'no',
             'checked' => TRUE,   // default value
             'style' => 'margin-left: 20px;'
            );
       echo form_radio($data); 
   ?>
   <?php echo form_label('No', 'signed_no'); ?>
   </div><!-- end of .form-control -->
   <div class="form-control">
        A signed confidentiality guideline is on file for this client.
        <?php 
             $data = array(
                 'name'  => 'guidelines_signed',
                 'value' => 'yes',
                 'style' => 'margin-left: 20px;'
                 );
            echo form_checkbox($data)); 
       ?>
   </div><!-- end of .form-control -->

How do I use set_radio() or set_checkbox() in this code? Nothing I try seems to work.

Why is nobody responding to this question?

Hi @WebMachine,

Sorry, I did spot the thread when you originally posted, but as I don’t have any experience with CodeIgniter I thought I’d hang back to see if anyone else could help and subsequently forgot all about it!

Looking through the docs, it seems that CI has two helpers for checkboxes: form_checkbox() for creating checkbox inputs, and set_checkbox() for repopulating their values after submission.

I think what you need to do is use both together:

echo form_checkbox(array(
    'name'    => 'guidelines_signed',
    'value'   => 'yes',
    'style'   => 'margin-left: 20px;',
    'checked' => set_checkbox('guidelines_signed', 'yes')
));

Thanks. I got it to work with the checkbox, but no luck with radio buttons. And when I Google the issue, it seems like this problem is fairly common, but no-one is coming up with solutions other than not using the CodeIgniter form helper for radio buttons. I finally gave up yesterday and switched to pure html and php for just my radio buttons, because my deadline is fast approaching.

BUT, I hate loose ends and still would like to know how to make it work using the CodeIgniter form helper way of doing things.
