I am creating a Api Extension with the help of Wordpress Header & Footer Integation

I am almost done and everything seems to be in order except, whenever I return a data, it always goes on the top of the browser, after the <body> tag, example given below:

PHP Code:


			
class wpHeaderFooter_Api_Options extends vB_Api_Extensions

{

    public $product = 'wpheaderfooter';

    public $version = '1.0.0';

    public $developer = 'me';

    public $title = 'WordPress Integration Extension';

    public $minver = '5.2.2';

    public $maxver = '5.9.99';

    public $infourl = '';

    public $checkurl = '';

    public $AutoInstall = 1;

    public $extensionOrder = 10;

    

    public function wpHeader($x){

        $path = $_SERVER['DOCUMENT_ROOT'];

           $path .= "/wpfolder/wp-content/themes/mytheme/header-forums.php";

           include_once($path);

           return;

    }

header-forums.php file simply contains an echo statement. VB displays it, but shows it on the top, even above the main-navbar-wrapper. However, the weird part is, if I do the following, it shows where the hook is supposed to show it

PHP Code:


			
class wpHeaderFooter_Api_Options extends vB_Api_Extensions

{

    public $product = 'wpheaderfooter';

    public $version = '1.0.0';

    public $developer = 'me';

    public $title = 'WordPress Integration Extension';

    public $minver = '5.2.2';

    public $maxver = '5.9.99';

    public $infourl = '';

    public $checkurl = '';

    public $AutoInstall = 1;

    public $extensionOrder = 10;

    

    public function wpHeader($x){

        //$path = $_SERVER['DOCUMENT_ROOT'];

           //$path .= "/wpfolder/wp-content/themes/mytheme/header-forums.php";

           //include_once($path);

           return "<h1>My Custom Footer</h1>";

    }

Any help would be highly appreciated.

The echo statement is the problem. VB wants to display the returned data. Assign your data to a variable and return the variable.

$data = '<h1>My Custom Footer</h1>';
return $data;

Well the issue isn't with the second piece of code from my post, outputting the following is causing the issue

PHP Code:


			
   public function wpHeader($x){ 

        $path = $_SERVER['DOCUMENT_ROOT']; 

           $path .= "/wpfolder/wp-content/themes/mytheme/header-forums.php"; 

           include_once($path); 

           return; 

    }

Using an echo will show at the top of the page like a debug marker. You need to remove the echo.

in your snippet, you're doing "return;"

You need to put the data in a variable and "return $data;"
