opendir(C:\php5\pear\Image\Barcode) [function.opendir]: fail

[gadjodilo]

Hi,

I just installed the image-barcode Package, but now I have a few
problems using it.

When I run the following code (http://localhost/test.php):

<?php
require_once("Image/Barcode.php");
$bc = new Image_Barcode;
$bc->draw($_GET['bctext'], "Code39", "png");
?>

I get the following error in my browser:

Warning: opendir(C:\php5\pear\Image\Barcode) [function.opendir]: failed
to open dir: Invalid argument in C:\xampp\php\pear\Image\Barcode.php on
line 66

Does anyone perhaps know a solution?

thank you in advance.

Grt,

Kabbi

(Does it have something to do with the: "C:\php5\pear\Image\Barcode" path? ... cause it doesn't exist. It should be "C:\xampp\php\pear\Image\Barcode" I Guess.... isn't it? But does anyone know where I can change / fix this?)

Code: Select all

 $barcodepath = PEAR_INSTALL_DIR . DIRECTORY_SEPARATOR . "Image" . DIRECTORY_SEPARATOR . "Barcode";
        $supportedtypes = array();
        if ( $incdir = opendir($barcodepath) ) {
            while ( false != ( $avaiabletype = readdir($incdir) ) ) {
                if ( strstr($avaiabletype, ".php") ) {
                    $supportedtypes[] = $avaiabletype;
                }
            }
            closedir($incdir);
        }

        if ( in_array($type . ".php", $supportedtypes) ) {
            include_once("Image/Barcode/${type}.php");
        } else {
            return PEAR::raiseError("$type barcode is not supported");
        }

        $classname = "Image_Barcode_${type}";

        if (!class_exists($classname)) {
            return PEAR::raiseError("Unable to include the Image/Barcode/${type}.php file");
        }

        if (!in_array('draw',get_class_methods($classname))) {
            return PEAR::raiseError("Unable to find create method in '$classname' class");
        }

        @$obj =& new $classname;

        $obj->draw($text, $imgtype);
    }

}

?>

When I open test.php in my browser I get the following error:

Warning: opendir(C:\php5\pear\Image\Barcode) [function.opendir]: failed to open dir: Invalid argument in C:\xampp\php\pear\Image\Barcode.php on line 66



This is the code of Barcode.php:

Code:

Code: Select all


require_once("PEAR.php");

class Image_Barcode extends PEAR
{

    function draw($text, $type = 'Code39', $imgtype = 'png') {

$barcodepath = PEAR_INSTALL_DIR . DIRECTORY_SEPARATOR . "Image" . DIRECTORY_SEPARATOR . "Barcode";
        $supportedtypes = array();
        if ( $incdir = opendir($barcodepath) ) {          /** <-- line 66*/
            while ( false != ( $avaiabletype = readdir($incdir) ) ) {
                if ( strstr($avaiabletype, ".php") ) {
                    $supportedtypes[] = $avaiabletype;
                }
            }
            closedir($incdir);
        }

        if ( in_array($type . ".php", $supportedtypes) ) {
            include_once("Image/Barcode/${type}.php");
        } else {
            return PEAR::raiseError("$type barcode is not supported");
        }

        $classname = "Image_Barcode_${type}";

        if (!class_exists($classname)) {
            return PEAR::raiseError("Unable to include the Image/Barcode/${type}.php file");
        }

        if (!in_array('draw',get_class_methods($classname))) {
            return PEAR::raiseError("Unable to find create method in '$classname' class");
        }

        @$obj =& new $classname;

        $obj->draw($text, $imgtype);
    }

}

?>


The test.php code:

Code:

Code: Select all

<?php
require_once("Image/Barcode.php");
$bc = new Image_Barcode;
$bc->draw($_GET['bctext'], "Code39", "png");
?>
 


The paths in my comp:

C:\xampp\php\pear\pear.php

C:\xampp\php\pear\Image\Barcode.php

C:\xampp\htdocs\test.php


I don't know if it's relevant but here is the pear.bat script:

Hi Wiedmann,

Thank you very much, I looked at the link and this actually works, the script is now being processed!

However, instead of an barcode image I get a line of text:

‰PNG  IHDR 2
ªK'PLTEÿÿÿ¥ÙŸÝIDATxœc(q-qeVÄ ‚ê@\•¸Á6IEND®B`‚

Do you perhaps also know a solution for this problem?

Grt,
Kabbi

[Wiedmann]

The sample script in your first post works correct.

Maybe you have some spaces and/or newlines before this code? Or you are using utf-8 as text format?

[gadjodilo]

Hi,

Yes I believe I'm using utf-8 as text format. This is not good? How and where should I change this?

Grt

[gadjodilo]

The barcode_img.php page which they included as an example works fine. However I'm only able to print numeric barcodes.. I set the code to code128 or Code39 It prints, but I can only read it with a scanner if it's numeric....
Has this also something to do with utf-8 ?

</body>
</html>

[gadjodilo]

Sorry for al this posts.

If I run this code:

Code: Select all

<?php

require_once("Image/Barcode.php");

$num = isset($_REQUEST['num']) ? $_REQUEST['num'] : '122312';
$type = isset($_REQUEST['type']) ? $_REQUEST['type'] : 'code128';
$imgtype = isset($_REQUEST['imgtype']) ? $_REQUEST['imgtype'] : 'png';

Image_Barcode::draw($num, $type, $imgtype);

?>


Then I'll get an barcode image. If I print this then it prints out 3 stickers(1 of 3 2 of 3 etc..).If I print it out and set in the print range pages from 1 till 1, then the image can be scanned by a scanner. However If I change the $num into a non numeric code like B-05-1023 for instance then it is impossible to scan the barcode image....

Is it because the image size should be adjusted??

(on the sticker there is still space left!)

Grt,

Kabbi

[gadjodilo]

Here I'am again .... it seems it is also possible to print and read characters like "b" "H" "F" etc... but nothing like "-" for instance... Is this correct? or can this be fixed.
Do you know?

[Wiedmann]

You should read the ISO/IEC 16388 documentation.

BTW: A dash is not possible.
