php7 Problem with FPDF

[rocky48]

I have used this program for many years without problems.
My ISP urged me to upgrade PHP to 7.2 and it was working OK.
Just went to use it and I get an error when parsing my FPDF file.
Here is the error:
Connected (added this to check if connected)
Fatal error: Uncaught Error: Call to undefined method PDF::FPDF() in /homepages/30/d593365489/htdocs/Prnpdf.php:78 Stack trace: #0 /homepages/30/d593365489/htdocs/Prnpdf.php(108): PDF->PDF('L', 'mm', 'A4') #1 {main} thrown in /homepages/30/d593365489/htdocs/Prnpdf.php on line 78

I have not altered the file in any way, so why is this happening?

Is it to do with PHP upgrade?😖

Here is the file:

<?php
include("connect_Verses4Cards.php");
$conn=get_db_conn_verse();
session_start();
$display_block ="";

$color="";
$r ="";
$g ="";
$b ="";
$image ="";

//Get the Card Variables
$Get_Size_sql = "SELECT * FROM `CSize` WHERE `Size` ='".$_POST["CSize"]."'";
$Get_Size_res =  mysqli_query($conn, $Get_Size_sql) or die(mysqli_error($conn));

if (mysqli_num_rows($Get_Size_res) < 1) {
	//this Card does not exist
	$display_block = "You have selected an invalid Card size.
	Please try again.";
} else {
	//get the print variables
	while ($Size_info = mysqli_fetch_array($Get_Size_res)) {
		$BoxX = stripslashes($Size_info['BoxX']);
		$Cellw = stripslashes($Size_info['Cellw']);
		$Cellh = stripslashes($Size_info['Cellh']);
		$SizeI = stripslashes($Size_info['Size']);
		$SID = stripslashes($Size_info['SID']);
		$floatx = stripslashes($Size_info['floatx']);
		$floaty = stripslashes($Size_info['floaty']);
		$floatw = stripslashes($Size_info['floatw']);
		$floath = stripslashes($Size_info['floath']);
		$ort = stripslashes($Size_info['ort']);
	}
		//create the display string
		$display_block = "$ort";
}
//verify the Event exists
//$the_id = mysqli_real_escape_string($mysqli, $_SESSION[VID]);
$Get_Verse_sql = "SELECT id, Event, Sub_Type, Verse FROM verses WHERE id='".$_SESSION['Test']."'";  
$Get_Verse_res =  mysqli_query($conn, $Get_Verse_sql) or die(mysqli_error($conn));


if (mysqli_num_rows($Get_Verse_res) < 1) {
	//this Event does not exist
	$display_block = "You have selected an invalid Event.
	Please try again.";
} else {
//get the Event ID
	while ($Verse_info = mysqli_fetch_array($Get_Verse_res)) {
		$Verse = stripslashes($Verse_info['Verse']);
	}
	//create the display string
	$display_block = "$Verse";
	
	//free results
	mysqli_free_result($Get_Verse_res);
	mysqli_free_result($Get_Size_res);
	//close connection to MySQL

}

	mysqli_close($conn);

Change

function PDF($orientation='P', $unit='mm', $size='A4')

to

function __construct($orientation='P', $unit='mm', $size='A4')

Giving the constructor function the same name as the class is very PHP version 4 and you can't get away with it any more.

You probably have to make the same amendment in your FPDF class also if it's an old version.

And also

$this->FPDF($orientation,$unit,$size);

to

parent::__construct($orientation,$unit,$size);

 

Assuming you don't have a very old version of FPDF, it should already be PHP 5 compatible (eg, using __construct) but it hasn't been updated in a few years and says it requires PHP 5.1.

Tried as suggested but get the same error!

Fatal error: Uncaught Error: Call to undefined method FPDF::FPDF() in /homepages/30/d593365489/htdocs/Prnpdf.php:78 Stack trace: #0 /homepages/30/d593365489/htdocs/Prnpdf.php(108): PDF->__construct('L', 'mm', 'A4') #1 {main} thrown in /homepages/30/d593365489/htdocs/Prnpdf.php on line 78

Also tried amending this line: $pdf = new PDF($ort,'mm','A4');  to: $pdf = new __construct($ort,'mm','A4');, but that did not work and gave this error:

Fatal error: Uncaught Error: Class '__construct' not found in /homepages/30/d593365489/htdocs/Prnpdf.php:108 Stack trace: #0 {main} thrown in /homepages/30/d593365489/htdocs/Prnpdf.php on line 108.

Where do I go rom here?

😂

You're createing a PDF object so that bit "new PDF()" stays the same

require('fpdf.php');

class PDF extends FPDF
{
    private $B;
    private $I;
    private $U;
    private $HREF;

    function __construct($orientation='P', $unit='mm', $size='A4')
    {
        // Call parent constructor
        parent::__construct($orientation,$unit,$size);
        // Initialization
        $this->B = 0;
        $this->I = 0;
        $this->U = 0;
        $this->HREF = '';
    }

}

...

$pdf = new PDF('L');

I think it was the parent bit that was stopping it!

However there are still problems! 

Here is the error:

Now I have cleared the original problem, It still errors!
Now it is finding fault with the font scripts. Here is the error:

Fatal error: Uncaught Exception: FPDF error: Incorrect font definition file name: /frscript.php in /homepages/30/d593365489/htdocs/fpdf.php:271 Stack trace: #0 /homepages/30/d593365489/htdocs/fpdf.php(1142): FPDF->Error('Incorrect font ...') #1 /homepages/30/d593365489/htdocs/fpdf.php(459): FPDF->_loadfont('/frscript.php') #2 /homepages/30/d593365489/htdocs/Prnpdf.php(110): FPDF->AddFont('french script m...', '', '/frscript.php') #3 {main} thrown in /homepages/30/d593365489/htdocs/fpdf.php on line 271

What is also wierd even if I change the font it still reports the error with the French Script font?

Had a quick look at the font file, but can't see anything wrong.
I'm guessing there is a change in the frscript.php, but I am not knowledgable to spot it! Before the upgrade to 7.2 it was working OK.
