What I'm trying to do is for a dual-language website. This particular language, Papiamento, isn't supported by Wordpress. Therefore, the client had to create two separate pages, in English and Pap. What I did was to code it like that to display English or Pap menu for each page.
Like this, in header.php:
<?php
if( is_page( array('salon-and-spa-pap', 'tocante-nos', 'testimonio', 'tuma-contacto-cu-nos', 'galeria', 'tratamentonan-di-masahe', 'tratamentonan-spa-di-curpa', 'servicionan-di-boda', 'tratamentonan-spa-di-cara', 'wowo-lip-nek', 'cuido-di-man', 'tratamento-di-huna', 'tratamento-di-huna-di-pia', 'cuido-di-pia', 'salon-p', 'spa-etiquette-pap', 'wax-p', 'reserva-un-tratamento')) ) {
wp_nav_menu(array( 'theme_location' => 'menu_top_pap' ) );
} else {
wp_nav_menu(array( 'theme_location' => 'secondary-menu' ) );
}
?>
However, the problem is that the client will have to keep going back to header.php to add another page slug every time she create a new page. Therefore, I created a Metabox plugin for that. I made a Metabox checkbox so that everytime a page is intended for Papiamento language, the client can just check the box and either the page id or slug will be added to the code above.
I found another question (https://wordpress.stackexchange.com/questions/71043/listing-pages-with-checkboxes-in-a-metabox-and-saving-them) that might be similar to what I was looking for but it didn't work for me.
Here's my metabox function based on this article (http://themefoundation.com/wordpress-meta-boxes-guide/).
<?php
function prfx_custom_meta() {
add_meta_box( 'prfx_meta', __( 'Papiamento Page Box', 'prfx-textdomain' ), 'prfx_meta_callback', 'page', 'normal', 'low' );
}
add_action( 'add_meta_boxes', 'prfx_custom_meta' );
function prfx_meta_callback( $post ) {
wp_nonce_field( basename( __FILE__ ), 'prfx_nonce' );
$prfx_stored_meta = get_post_meta( $post->ID );
$checkfield = maybe_unserialize( get_post_meta($post->ID, "checkfield", true) );
?>
<p>
<span class="prfx-row-title"><?php _e( 'Pap Checkbox', 'prfx-textdomain' )?></span>
<div class="prfx-row-content">
<label for="meta-checkbox">
<input type="checkbox" name="checkfield[]" id="page_<?php echo $page->ID; ?>" value="<?php echo $page->ID; ?>" <?php if ( in_array($page->ID, (array) $checkfield) ) { ?> checked <?php } ?>/> <label for="page_<?php echo $page->ID; ?>"><?php echo $page->post_title; ?>
<?php _e( 'Check if this page is Papiamento', 'prfx-textdomain' )?>
</label>
</div>
</p>
<?php
}
/**
* Saves the custom meta input
*/
function prfx_meta_save( $post_id ) {
// Checks save status
$is_autosave = wp_is_post_autosave( $post_id );
$is_revision = wp_is_post_revision( $post_id );
$is_valid_nonce = ( isset( $_POST[ 'prfx_nonce' ] ) && wp_verify_nonce( $_POST[ 'prfx_nonce' ], basename( __FILE__ ) ) ) ? 'true' : 'false';
// Exits script depending on save status
if ( $is_autosave || $is_revision || !$is_valid_nonce ) {
return;
}
// Checks for input and sanitizes/saves if needed
// Checks for input and saves
if( isset( $_POST[ 'checkfield' ] ) ) {
update_post_meta($post_id, "checkfield", $_POST['checkfield'] );
}
}
add_action( 'save_post', 'prfx_meta_save' );
and calling the page id in header.php like this:
<?php
if( in_array($page->ID, (array) $checkfield) ) {
wp_nav_menu(array( 'theme_location' => 'menu_top_pap' ) );
} else {
wp_nav_menu(array( 'theme_location' => 'secondary-menu' ) );
}
?>
But it didn't work. Please help!
***************** UPDATE ***************** I've been trying to edit the function prfx_meta_callback( $post ) but with no success. Here's the latest code I'm trying to modify...
function prfx_meta_callback( $post ) {
wp_nonce_field( basename( __FILE__ ), 'prfx_nonce' );
$checkfield = maybe_unserialize( get_post_meta($post->ID, "checkfield", true) );
$page = get_pages();
$prfx_stored_meta = get_post_meta( $post->ID );
?>
<p>
<span class="prfx-row-title"><?php _e( 'Pap Checkbox', 'prfx-textdomain' )?></span>
<div class="prfx-row-content">
<label for="page_<?php echo $page->ID; ?>">
<input id="page_<?php echo $page->ID; ?>" type="checkbox" name="checkfield[]" value="<?php echo $page->ID; ?>" <?php if ( isset($checkfield [ ?>'<?php echo $page->ID; ?>'<?php ] ) ) checked( $checkfield[ ?>'<?php echo $page->ID; ?>'<?php ][0], '<?php echo $page->ID; ?>'); ?>/> <?php _e( 'Check if this page is Papiamento', 'prfx-textdomain' )?></label> <br>
</div>
</p>

I've been trying to make it like that, if Pap, then checked, but if not Pap, unchecked in every page.
If the metabox is saving the checkbox settings properly, you can use the following code to make the check in header.php:
if ( in_array( get_the_ID(), get_post_meta( get_the_ID(), 'checkfield', true ) ) ) {
wp_nav_menu(array( 'theme_location' => 'menu_top_pap' ) );
} else {
wp_nav_menu(array( 'theme_location' => 'secondary-menu' ) );
}
