Barcode (Code 128) Problem

[madd_maxx]

Hi @ all,

did anyone use a converting of numbers (like ticket numbers) for this barcode type anytime? a font type for that I have already.

I tried to translate a VB script into php. unfortunately my output isn´t correct. however I don´t know what should I do.

thx in advance

Ok, maybe explaining your problem a little more might get more users helping out. At the moment all i know is your converting VB to PHP.

ok, below you will find the source for the problem..... if I put the ticket no. 123456789012 into the converting function I get the following code 'ÉÄ!7Mcy! 2 RË the right return value (formated for code128 barcode) have to be Ê,BXnz,VË

$chars = array();
$chrs = array();

function ConvertToCode128( $Ticket )
{
	$l = strlen( $Ticket );
	$chars[0] = '';
	for( $i=1; $i <= $l; $i++ )
	{
		$chars[$i] = substr( $Ticket, $i-1, 1 );
	}

	$ind = 0;
	$temp = $chars;
	$start = 104;
	$mode = 0;
	$m = 1;
	for( $i=1; $i<=$l+1; $i++ )
	{
		$sw = true;
		if( $i < $l + 1 )
		{
			if(ord($temp[$i]) > 47 && ord($temp[$i]) < 58) $digit = 1; // Wenn Position eine Ziffer ist
			if( ($mode=0 && !isset($digit)) || ($mode=1 && isset($digit)) ) $sw = false;	
		}
		if( $mode==0 )
		{
			if( $sw ) 
			{
				$mode = 1;
				$ind = $i;
			} 
			else
			{
				$chrs[$m] = ord($temp[$i]) - 32;
				$m++;
			}			
		} 
		elseif( $sw )
		{
			if( $i-$ind < 4 )
			{
				for( $j=0; $j <= $i-$ind-1; $j++ )
				{
					$chrs[$m+$j] = ord( $temp[$ind + $j] ) - 32;
				}
				$m = $m+$i-$ind;
				if( $i < $l+1 )
				{
					$chrs[$m] = ord( $temp[$i] ) - 32;
					$m++;
				} 
			}
			else
			{
				if( $ind == 1 ) $start = 105;
				else $chrs[$m] = 99; $m++;

				$n = floor( ($i - $ind) / 2 );			
				for( $j = 0; $j <= $n - 1; $j++ )
				{
					$chrs[$m + $j] = 10 * $temp[$ind + 2 * $j] + $temp[ $ind + 2 * $j + 1 ];
				}
				$m = $m + $n;
				if( $i < $l+1 ) $chrs[$m] = 100; $m++;
				if( fmod( $i-$ind, 2 ) == 1 ) $chrs[$m] = ord( $temp[$i-1] ) - 32; $m++;
				if( $i < $l+1 ) $chrs[$m] = ord( $temp[$i] ) - 32; $m++;
			}
			$mode = 0;
		}
	}
	$check = $start;
	for( $i=1; $i <= $m-1; $i++ )
	{
		$check = $check + $chrs[$i] * $i;
	}
	$chrs[$m] = fmod( $check, 103 );

	for( $i=1; $i <= $m; $i++ )
	{
		if( $chrs[$i] < 96 ) $chrs[$i] = Chr( $chrs[$i] + 32 );
		else $chrs[$i] = Chr( $chrs[$i] + 97 );
	}

	$convert = Chr( $start + 97 ) . implode( '', $chrs ) . Chr(203);
	return $convert;
