Repopulate radio buttons on failed validation

Question

I have a form that pulls data from a database. Code works fine if it’s an input box but I can’t get the latest $_POST data for radio buttons.

This works for input text box. I get default values pulled from the DB on first load, and I can get the new input (if any) from the user modifies the input box on a failed validation.

<?php echo form_input('email',set_value('email', $email)); ?>

Here’s the code for one of my radio button. It works when I’m pulling data from the DB, but if the form refreshes due to a failed validation, I’m not sure how I can show what the user selected.

<input type="radio" name="gender" value="male" <?php if($gender == "male") echo "checked";  ?> />Male

I played around with set_radio but i ran into the same issue. This works on initial load, but what about on a failed validation? I tried throwing "set_radio" in the second paramter but that didn't work either.

if($gender == "male") {
    echo form_radio('gender', 'male',TRUE)
} else {
   echo form_radio('gender', 'male')
}

Answer 1

From the CodeIgniter UserGuide.

<input type="radio" name="myradio" value="1" <?php echo set_radio('myradio', '1', TRUE); ?> />

<input type="radio" name="myradio" value="2" <?php echo set_radio('myradio', '2'); ?> />

The first parameter is the name of the radio set, the second is the current radio's value, and the third is an option default if there is no data to populate the field with.

Looks like I was able to use the same code as I would for a text box.
