PHP FPDF page break

Question

I am using PHP and FPDF to generate a PDF with a list of items. I have a loop and in the loop I have a verification with GetY() to check when will be the break. This work fine but on the first page, no. It's creating pages, but in the first page no break the texto to second page like others. What should I do?

[...]
if ($pdf->GetY() > 230) {
     $pdf->AddPage();
} 
endwhile;

Full Code:

if($_GET['print'] == 'ok'){
$idO = $_GET['id'];
require_once "assets/fpdf/fpdf.php";

$pdf = new FPDF( 'P', 'mm', 'A4' );

$pdf->AddPage();
$pdf->SetFillColor( 255, 255, 255 );
$pdf->SetDrawColor( 255, 255, 255 );
$pdf->AliasNbPages();
$pdf->SetAutoPageBreak(true, 30);

$itens = get_field('itens', $idO);
$args = array(
    'post_type' => 'categorias',
    'posts_per_page' => -1,
    'meta_key' => 'ordem',
    'orderby' => 'meta_value',
    'order' => 'ASC',
    'meta_query' => array(
        'key' => 'status',
        'value' => 'ativo',
        'compare' => '='
    )
);

$query = new WP_Query($args);
$i=0;
while ($query->have_posts()):$query->the_post();
    foreach ($itens as $key => $value){
        if(get_field('categoria', $value) == get_the_ID()){
            $i++;

            $pdf->SetFont( 'Arial', 'B', 10 );

            if($i == 1){
                $pdf->MultiCell( 0, 10, utf8_decode(html_entity_decode(get_the_title($value))).':', 0, 'C', false );
                $imgWidth = 65;
                $f = get_field('principal', $value);
                $wI = get_field('_wp_attachment_metadata', get_field('foto'.$f, $value))['width'];
                $hI = get_field('_wp_attachment_metadata', get_field('foto'.$f, $value))['height'];

                $pY = ($imgWidth * $hI) / $wI;

                $pX = ($pdf->GetPageWidth() - $imgWidth) / 2;

                $img = wp_get_attachment_image_src( get_field('foto'.$f, $value), 'full' )[0];
                $pdf->Image($img,$pX,$pdf->GetY(),$imgWidth);

                $pdf->MultiCell( 0, 5, "Gabinete:", 0, 'L', false );
            } else{

                        $imgWidth2 = 20;
                        $wtP = ($imgWidth2 * $x);
                        $pX2 = ($x == 1)?($pdf->GetX() + $wtP):($pdf->GetX() + $wtP + 5);

            if ($pdf->GetY() > 265) {

        $pdf->Ln( 2 );
    }
endwhile;
wp_reset_query();

$pdf->Output('', 'relatorio.pdf');
die();

}

Answer 1

Instead make an IF() and use GETY () because you do not use SETY ()? Creating a footer.

instead of:

if ($pdf->GetY() > 265) {
     $pdf->AddPage();
}

do that:

// set your value
$this->SetY(-15);
$pdf->AddPage();

Look at this official example

Answer 2

seems that "SetAutoPageBreak" isn't work on the first page, only on the others. The code is creating pages, but don't breaking on the first
