Adding watermark to PDF with php

Coursesweb next problem I try for hours to add watermark in my php document.

I getting errors or non result

Code: Select all

class PDF_Rotate extends FPDF is implent succesfull
I don`t get any result or errors when I place it on a wrong line.
Even $txt I don`t wanna have in my document but only the watermark.

The script is succesfull with even adding new line from post_text
what I asked in the topic before (found this solution by my self)

Hope you can help me with this ????

Code: Select all

<?php 
  
include('connection.php');

$id = (int) $_GET['id'];

$sql=mysqli_query($conn,"SELECT * FROM `w3_post` WHERE post_id='" . $id . "' ");
$users=mysqli_fetch_assoc($sql);
?>

<?php
include('database.php');
$database = new Database();
$result = $database->runQuery("SELECT title,post_text FROM w3_post where title='Wit Rusland Belarus'");
$header = $database->runQuery("SELECT UCASE(`COLUMN_NAME`) 
FROM `INFORMATION_SCHEMA`.`COLUMNS` 
WHERE `TABLE_SCHEMA`='comments' 
AND `TABLE_NAME`='w3_post'
and `COLUMN_NAME` in ('title','post_text')");

require('fpdf/fpdf.php');

?>

Code: Select all

<?php

class PDF_Rotate extends FPDF
{
var $angle=0;

function Rotate($angle,$x=-1,$y=-1)
{
	if($x==-1)
		$x=$this->x;
	if($y==-1)
		$y=$this->y;
	if($this->angle!=0)
		$this->_out('Q');
	$this->angle=$angle;
	if($angle!=0)
	{
		$angle*=M_PI/180;
		$c=cos($angle);
		$s=sin($angle);
		$cx=$x*$this->k;
		$cy=($this->h-$y)*$this->k;
		$this->_out(sprintf('q %.5F %.5F %.5F %.5F %.2F %.2F cm 1 0 0 1 %.2F %.2F cm',$c,$s,-$s,$c,$cx,$cy,-$cx,-$cy));
	}
}

function _endpage()
{
	if($this->angle!=0)
	{
		$this->angle=0;
		$this->_out('Q');
	}
	parent::_endpage();
}
}

?>

	$this->RotatedText(35,190,'W a t e r m a r k   d e m o',45);
}

function RotatedText($x, $y, $txt, $angle)
{
	//Text rotated around its origin
	$this->Rotate($angle,$x,$y);
	$this->Text($x,$y,$txt);

}
}

$pdf=new PDF();
$pdf->AddPage();
$pdf->SetFont('Arial','',12);
$txt="FPDF is a PHP class which allows to generate PDF files with pure PHP, that is to say ".
