Conditional lodgic for form id

I am creating a pdf from PHP which works great, but I need to use conditional logic to print the correct fields on the pdf when the user hits submit. Right now it does not print any fields when I try to add conditional logic in. Here is the code I am using.

if ( ! is_admin() ) { // phpcs:ignore
	if( $form->id === 4 ){ // phpcs:ignore
		if ( $_POST ) { // phpcs:ignore
			require 'fpdf.php';
			$coursename = $_POST['item_meta'][32]; // phpcs:ignore
			$name       = $_POST['item_meta'][36]; // phpcs:ignore
			$doc        = date( "m/d/Y" ); // phpcs:ignore

			$pdf = new FPDF();
			$pdf->AddPage( 'L' );
			$pdf->Image( 'wp-content/themes/mwp/fpdf/Yalicert.jpg', 0, 0, 300, 210, 'JPG' );
			$pdf->SetFont( 'Arial', 'B', 15 );

			$pdf->Cell( 0, 170, $coursename, 100, 1, 'C' );

			$pdf->SetX( 55 );
			$pdf->Cell( 0, -15, $doc, 0, 1, 'L' );

			$pdf->Cell( 0, -50, $name, 0, 0, 'C' );

			$pdf->Output();
		}
	} elseif( $form->id === 3  ) { // phpcs:ignore
		if ( $_POST ) { // phpcs:ignore
			require 'fpdf.php';
			$coursename = $_POST['item_meta'][7]; // phpcs:ignore
			$name       = $_POST['item_meta'][10]; // phpcs:ignore
			$doc        = 'Gre'; // phpcs:ignore

			$pdf = new FPDF();
			$pdf->AddPage( 'L' );
			$pdf->Image( 'wp-content/themes/mwp/fpdf/Yalicert.jpg', 0, 0, 300, 210, 'JPG' );
			$pdf->SetFont( 'Arial', 'B', 15 );

			$pdf->Cell( 0, 170, $coursename, 100, 1, 'C' );

			$pdf->SetX( 55 );
			$pdf->Cell( 0, -15, $doc, 0, 1, 'L' );

			$pdf->Cell( 0, -50, $name, 0, 0, 'C' );

			$pdf->Output();
		}
	} if( $form->id === 2 ) { // phpcs:ignore
		if ( $_POST ) { // phpcs:ignore
			require 'fpdf.php';
			$coursename = $_POST['item_meta'][20]; // phpcs:ignore
			$name       = $_POST['item_meta'][23]; // phpcs:ignore
			$doc        = 'Port'; // phpcs:ignore

			$pdf = new FPDF();
			$pdf->AddPage( 'L' );
			$pdf->Image( 'wp-content/themes/mwp/fpdf/Yalicert.jpg', 0, 0, 300, 210, 'JPG' );
			$pdf->SetFont( 'Arial', 'B', 15 );

			$pdf->Cell( 0, 170, $coursename, 100, 1, 'C' );

			$pdf->SetX( 55 );
			$pdf->Cell( 0, -15, $doc, 0, 1, 'L' );

			$pdf->Cell( 0, -50, $name, 0, 0, 'C' );

			$pdf->Output();
		}
	}
