Save custom field types with this function...?

Question

I found this great article (right here) about creating and saving custom fields for user profiles. The problem is that it only saves text fields. I can't save checkboxes, radio, or any other field types.

Here is the code I am using in the functions.php of my theme:

<?php

add_action( 'show_user_profile', 'my_show_extra_profile_fields' );
add_action( 'edit_user_profile', 'my_show_extra_profile_fields' );

function my_show_extra_profile_fields( $user ) { ?>


    <h3>Extra profile information</h3>

    <table class="form-table">

        <tr>

            <td>
                <input type="text" name="test" id="test" value="<?php echo esc_attr( get_the_author_meta( 'test', $user->ID ) ); ?>" class="regular-text" /><br />
            </td>
        </tr>

        <tr>

            <td>
                <input type="checkbox" name="test2" id="test2" value="<?php echo esc_attr( get_the_author_meta( 'test2', $user->ID ) ); ?>" class="regular-text" /><br />
            </td>
        </tr>

    </table>


<?php } 

add_action( 'personal_options_update', 'my_save_extra_profile_fields' );
add_action( 'edit_user_profile_update', 'my_save_extra_profile_fields' );

function my_save_extra_profile_fields( $user_id ) {

    if ( !current_user_can( 'edit_user', $user_id ) )
        return false;

    /* Copy and paste this line for additional fields. Make sure to change 'twitter' to the field ID. */
    update_usermeta( $user_id, 'test', $_POST['test'] );
    update_usermeta( $user_id, 'test2', $_POST['test2'] );
}

?>

In this sample, the "test" field saves, but the "test2" field doesn't.

Does anyone know how to save different field types (checkboxes, radio, dropdown, etc.) using this code?

Thanks a lot!

Answer 1

How do you know that the checkbox value is not being saved? I'm guessing that it is saved to the database; however, in your code, you do not have any method of setting the "checked" attribute for the checkbox to "checked". As such, you will not see the boxed checked.

You'll need something like the following to achieve this effect.

<?php $checked = ( get_the_author_meta( 'test2', $user->ID ) == 'some-value' ) ? ' checked="checked" : ''; ?>
<input type="checkbox" name="test2" id="test2" value="some-value" class="regular-text"<?php echo $checked; ?> /><br />

Just make sure to change "some-value" to the value that you want.
