Ultimate Membership Pro - Member Checkbox and Filter Strings Not Translatable

Overview of the issue

When using Ultimate Membership Pro with WPML, you might experience an issue where checkbox values used in member profiles and directory filters are not translatable. and prevents translated labels from appearing correctly on translated directory pages or forms.

Workaround

Please make sure you have a full backup of your site before proceeding.

1- Delete Incorrect Translations

• Go to WPML > String Translation
• Filter by Translation Complete
• Search for strings under the field name [ihc_user_fields]
• Select all these strings and delete them – they are value strings and should not be translated.

2- Modify Frontend Filter Template

• Open: wp-content/plugins/indeed-membership-pro/public/views/listing_users-filter.php
• Look for: Line 167 under the case ‘checkbox’

Replace:

<?php
foreach ($field['values'] as $v){
    if (is_array($get_value)){
        $checked = (in_array($v, $get_value)) ? 'checked' : '';
    } else {
        $checked = ($v==$get_value) ? 'checked' : '';
    }
    ?>
    <div class="iump-form-checkbox">
        <input type="checkbox" name="<?php echo esc_attr($field['name']);?>[]" value="<?php echo esc_attr(ihc_correct_text($v));?>" <?php echo esc_attr($checked);?> />
        <?php echo esc_html(ihc_correct_text($v));?>
    </div>
    <?php
}
?>

With:

<?php
foreach ($field['values'] as $v){
    if (is_array($get_value)){
        $checked = (in_array($v, $get_value)) ? 'checked' : '';
    } else {
        $checked = ($v==$get_value) ? 'checked' : '';
    }

    // WPML: Separate value and label
    $wpml_original_value = ihc_correct_text($v);
    $wpml_string_name = 'checkbox_option_' . $field['name']; 
    do_action( 'wpml_register_single_string', 'ihc', $wpml_string_name . '_' . sanitize_title($v), $wpml_original_value );
    $wpml_translated_label = apply_filters( 'wpml_translate_single_string', $wpml_original_value, 'ihc', $wpml_string_name . '_' . sanitize_title($v) );
?>
    <div class="iump-form-checkbox">
        <input type="checkbox" name="<?php echo esc_attr($field['name']);?>[]" value="<?php echo esc_attr(ihc_correct_text($v));?>" <?php echo esc_attr($checked);?> />
        <?php echo esc_html($wpml_translated_label); ?>
    </div>
<?php
}
?>

3- Fix Registration Form Checkbox Labels

• Open: wp-content/plugins/indeed-membership-pro/classes/IndeedForms.php
• Look for: The checkbox function (around line 129)

Replace:

$output .= ihc_correct_text( $v );

With:

$output .= __( ihc_correct_text( $v ), 'ihc' );</ul>

4- Trigger String Registration

• Visit the directory page on the frontend to load new strings.
• Go to WPML > String Translation and translate only the newly registered strings under the «ihc» domain (named like checkbox_option_name).
