I just found out that my clients server uses php 5.2.17 and I have anonymous functions all over the place. I know I have to name them but apparently I'm doing it all wrong as its not working and I'm getting a t_function error.

 

function add_post_type($name, $args= array()) {
add_action('init', function() use($name, $args) {
$upper = ucwords($name);
$name = strtolower(str_replace(' ', '_', $name));
$args = array_merge(
array(
'public' => true,
'label'	 => "$upper" . 's',
'labels' => array('add_new_item' => "Add New $upper"),
'rewrite' => array(
 'slug' => 'books'
	 ),
 'query_var'	 => true,
'supports' => array('title', 'editor', 'comments', 'excerpt', 'thumbnail'),
'capability_type'=> 'page',
'hierarchical'	 => true
),
$args
);
register_post_type( $name, $args );
});
}

 

I tried naming the function in the second line and creating a callback function but apparently I'm doing it wrong.

Any help would be much appreciated.

what exactly are u trying to do in wordpress?

A custom post type with a meta box that inserts an associated url. That was only a piece of it. Here's the whole thing:

function add_post_type($name, $args= array()) {
add_action('init', function() use($name, $args) {
 $upper = ucwords($name);
 $name = strtolower(str_replace(' ', '_', $name));
 $args = array_merge(
  array(
   'public'    => true,
   'label'    => "$upper" . 's',
   'labels'    => array('add_new_item' => "Add New $upper"),
   'rewrite' => array(
   'slug' => 'books'
	   ),
    'query_var'		 => true,
   'supports'    => array('title', 'editor', 'comments', 'excerpt', 'thumbnail'),
   'capability_type'=> 'page',
   'hierarchical'   => true
   ),
   $args
  );
 register_post_type( $name, $args );
});
}
add_post_type('book', array());
   // Create out post type
   add_action( 'init', 'create_post_type' );
   function create_post_type() {
	    $args = array(
	    'labels' => post_type_labels( 'Book' ),
	    'public' => true,
	    'publicly_queryable' => true,
	    'show_ui' => true,
	    'show_in_menu' => true,
	    'query_var' => true,
	    'rewrite' => true,
	    'capability_type' => 'post',
	    'has_archive' => true,
	    'hierarchical' => false,
	    'menu_position' => null,
	    'supports' => array('title',
		    'editor',
		    'author',
		    'thumbnail',
		    'excerpt',
		    'comments'
	    )
    );
	    register_post_type( 'book', $args );
   }
   // A helper function for generating the labels
   function post_type_labels( $singular, $plural = '' )
   {
    if( $plural == '') $plural = $singular .'s';
    return array(
	    'name' => _x( $plural, 'post type general name' ),

	    'view_item' => __( 'View '. $singular ),
	    'search_items' => __( 'Search '. $plural ),
	    'not_found' =>  __( 'No '. $plural .' found' ),
	    'not_found_in_trash' => __( 'No '. $plural .' found in Trash' ),
	    'parent_item_colon' => ''
    );
   }


   //add filter to ensure the text Book, or book, is displayed when user updates a book
   add_filter('post_updated_messages', 'post_type_updated_messages');
   function post_type_updated_messages( $messages ) {
	    global $post, $post_ID;
	    $messages['book'] = array(
			    0 => '', // Unused. Messages start at index 1.

			    // translators: Publish box date format, see php.net/date
			    date_i18n( __( 'M j, Y @ G:i' ), strtotime( $post->post_date ) ), esc_url( get_permalink($post_ID) ) ),

	    );
	    return $messages;
   }


add_action('add_meta_boxes', function() {
add_meta_box(
 'kc_buy_now',

global $post;
$url = get_post_meta($post->ID, 'buy_now_associated_url', true);

//unique identifier, name of hidden field
wp_nonce_field(__FILE__, 'kc_nonce');
?>
<label for="buy_now_associated_url">Associated URL:</label>
<input type="text" name="buy_now_associated_url" id="buy_now_associated_url" class="widefat" value="" /><?php
 echo $url;
}
add_action('save_post', function() {
global  $post;
if (defined('DOING_AUTOSAVE') && DOING_AUTOSAVE ) return;
//security check nonce
if($_POST && !wp_verify_nonce($_POST['kc_nonce'], __FILE__) ) {
 return;
}
if (isset($_POST['buy_now_associated_url']) ) {
 update_post_meta($post->ID, 'buy_now_associated_url', $_POST['buy_now_associated_url']);
}
});

 

Its a bit of a muddle as I was trying to learn as I went along but it was working locally.
