php - Managing a new page in tcpdf -

i'm generating pdf reports in php using tcpdf. first page positions textbox correctly down page, textboxes in subsequent pages placed in header(one textbox per page) making document long.

//code   require_once('../report/header.php');  // add page  $pdf->addpage();  $p=30;  ($i = 30; $i < 1000; $i = $i + 20) {       $pdf->createtextbox('patient card' . $i, 30, $p, 120, 40, 20);   $p=$p+20;  } 

i have made solution detects if have reached bottom of page try , fix above not usable incase of dynamic text(where text database). solution adds new page in case have reached value in y axis , resets y axis

//code  require_once('../report/header.php');  // add page  $pdf->addpage();  $p=30;  ($i = 30; $i < 1000; $i = $i + 20) {    $pdf->createtextbox('patient card' . $i, 30, $p, 120, 40, 20);   if ($i == 230 || $i == 430 || $i==......){     $pdf->addpage();     $p=30;            }   $p=$p+20;  } 

is there way new pages can added automatically , value of y axis reset new page?
