I have found solution.
Now I use wpalchemy for create custom metabox and custom fields.

WPAlchemy

how can I use the variable $do_not_duplicate = $post-> ID in this loop for not having duplicate posts?

Best Regards

Yhea ??

I now paste the html code that I create with the editor of posts.
It’s very frustrating work ??

Sorry but I haven’t resolved it. ??

Hi, web00132

I put this code on function.php and it work perfectly.

function my_meta_init()
{
	// review the function reference for parameter details
	// https://codex.www.ads-software.com/Function_Reference/wp_enqueue_script
	// https://codex.www.ads-software.com/Function_Reference/wp_enqueue_style

	//wp_enqueue_script('my_meta_js', MY_THEME_PATH . '/custom/meta.js', array('jquery'));
	wp_enqueue_style('my_meta_css', MY_THEME_PATH . '/custom/meta.css');

	// review the function reference for parameter details
	// https://codex.www.ads-software.com/Function_Reference/add_meta_box

	// add a meta box for each of the wordpress page types: posts and pages
	foreach (array('post','page', 'books', 'movies') as $type)
	{
		add_meta_box('my_all_meta', 'My custom box', 'my_meta_setup', $type, 'normal', 'high');
	}

	// add a callback function to save any data a user enters in
	add_action('save_post','my_meta_save');
}

function my_meta_setup()
{
	global $post;

	// using an underscore, prevents the meta variable
	// from showing up in the custom fields section
	$meta = get_post_meta($post->ID,'_my_meta',TRUE);

	// instead of writing HTML here, lets do an include
	include(MY_THEME_FOLDER . '/custom/meta.php');

	// create a custom nonce for submit verification later
	echo '<input type="hidden" name="my_meta_noncename" value="' . wp_create_nonce(__FILE__) . '" />';
}

function my_meta_save($post_id)
{
	// authentication checks

	// make sure data came from our meta box
	if (!wp_verify_nonce($_POST['my_meta_noncename'],__FILE__)) return $post_id;

	// check user permissions
	if ($_POST['post_type'] == 'page')
	{
		if (!current_user_can('edit_page', $post_id)) return $post_id;
	}
	else
	{
		if (!current_user_can('edit_post', $post_id)) return $post_id;
	}

	// authentication passed, save data

	// var types
	// single: _my_meta[var]
	// array: _my_meta[var][]
	// grouped array: _my_meta[var_group][0][var_1], _my_meta[var_group][0][var_2]

	$current_data = get_post_meta($post_id, '_my_meta', TRUE);	

	$new_data = $_POST['_my_meta'];

	my_meta_clean($new_data);

	if ($current_data)
	{
		if (is_null($new_data)) delete_post_meta($post_id,'_my_meta');
		else update_post_meta($post_id,'_my_meta',$new_data);
	}
	elseif (!is_null($new_data))
	{
		add_post_meta($post_id,'_my_meta',$new_data,TRUE);
	}

	return $post_id;
}

function my_meta_clean(&$arr)
{
	if (is_array($arr))
	{
		foreach ($arr as $i => $v)
		{
			if (is_array($arr[$i]))
			{
				my_meta_clean($arr[$i]);

				if (!count($arr[$i]))
				{
					unset($arr[$i]);
				}
			}
			else
			{
				if (trim($arr[$i]) == '')
				{
					unset($arr[$i]);
				}
			}
		}

		if (!count($arr))
		{
			$arr = NULL;
		}
	}
}

Bye

I find the solution ??
It’s simple. I have used this code for implement meta box:

// add a meta box for each of the wordpress page types: posts and pages and other custom post type
	foreach (array('post','page', 'books', 'movies', 'products') as $type)
	{
		add_meta_box('my_all_meta', 'My custom box', 'my_meta_setup', $type, 'normal', 'high');
	}
