Get post_type in current_screen

Hello,

Thanks you for this great plugin.

Most of the time I use mqtranslate for the multilingual sites. So I’m adding a feature so the admin can chose the custom post types that don’t require mqtranslate. Or the custom post type that get corrupted by the mqtranslate (the case of tazblepress).

I already fix this problem for several plugins (cform7, cpt-onomies, etc) where I didn’t have a problem to get the post_type but in tablepress I’m unable to retrieve the post_type.

Exemple I’m in :
http://example.com/wp-admin/admin.php?page=tablepress&action=edit&table_id=24

In this screen I’m trying to retrieve the post_type
like this

function qtrans_disableTranslation(){
	global $q_config;
	echo "<pre>"; var_dump(qtrans_getCurrentPostType()) ; echo "</pre>"; //Tablepress always return null or wrong post_type
	if( in_array(qtrans_getCurrentPostType(), $q_config['ignored_custompost'] ) ) {
		define('QT_DISABLED', true);
		return false;
	}
	/**/
	return true;
}
function qtrans_admin_notice_disabled_bypost() {

	if(!qtrans_disableTranslation()):
		?>
	<div class="update-nag">
		<p><?php _e( 'Translation disabled on this post type', 'mqtranslate' ); ?></p>
	</div>
	<?php
	endif;
}
add_action( 'admin_notices', 'qtrans_admin_notice_disabled_bypost' );

function qtrans_getCurrentPostType() {
	global $post, $typenow, $current_screen, $post_type;

	if( $post_type ) return $post_type;

	$post_id = ( isset($_GET['post']) ) ? $_GET['post'] : ( isset($_POST['post_ID']) ) ? $_POST['post_ID'] : 0;

	$post = NULL;
	$post_type_object = NULL;
	if ( $post_id && $post = get_post($post_id) ) {
		if ( $post_type_object = get_post_type_object($post->post_type) ) {
			return $post_type_object->name;
		}
	} elseif ( isset($_POST['post_type']) && $post_type_object = get_post_type_object($_POST['post_type']) ) {
		return $post_type_object->name;
	}  elseif( $typenow ){
		return $typenow;
	} elseif( $current_screen && $current_screen->post_type ){
		return  $current_screen->post_type;
	} elseif( isset( $_REQUEST['post_type'] ) ){
		return  sanitize_key( $_REQUEST['post_type'] );
	}elseif (get_post_type($_REQUEST['post'])){
		return get_post_type($_REQUEST['post']);
	}
	//last chance to get the post_type (this can be wrong)
	$regex = "/^.*(id)$/i";
	$vars = array();
	foreach($_GET as $name=>$value) {
		if(preg_match($regex, $name)) {
			$vars[$name] = $value;
			if ( $post = get_post($value) ) {
				if ( $post_type_object = get_post_type_object($post->post_type) ) {
					return  $post_type_object->name;
				}
			}
		}
	}
	return "undefined_posttype";
}

At the end of qtrans_getCurrentPostType I’m doing a loop to see if we have in the query something like xxxx_id and try to guest the posttype by that ID… but in tablepress table_id is not the same as the post’s id.
So for example in my case table_id=24 will uses the wp_posts with the ID 586

MMMMhhhh…. hope I was clear.
By the way I tried several actions in the add_action (http://codex.wordpress.org/Plugin_API/Action_Reference) without success

Well I can do that but I really don’t like to work with exceptions when working with a framework.

The condition to get the post_type of tablepress is kind of dirty and must be configured by hand :

function qtrans_customTest($test_parent_screen,$test_action, $post_type){
		$screen = get_current_screen();
		$current_parent_screen = $screen->parent_base;
		if(!$current_action = $screen->action){
			$current_action = $screen->base;
			$test_action = $current_parent_screen.'_'.$test_action  ;
		}
		return ($current_parent_screen == $test_parent_screen && $current_action == $test_action) ? $post_type : false;
}

And the condition :

if( defined( 'TABLEPRESS_ABSPATH' ) && $post_type = qtrans_customTest('tablepress', 'edit', 'tablepress_table') ){
		return $post_type ;
	}

That would be great if tablepress return WP_Screen with all the variables filled in the object.
Well this is my 2 cents 🙂

thanks for the support
