如何在视图中访问ZF2条形码

Question

I would like to render multiple Zend Framework 2 barcodes on a page.

I have been following this example (although it is for ZF1) Zend Framework Render Barcodes Into PDF Pages

I am currently using DOMPDFModule to create a pdf.

How do I display the barcode using ZF2? How can I render them in the view?

    // Only the text to draw is required
    $barcodeOptions = array('text' => 'ZEND-FRAMEWORK');

    // No required options
    $rendererOptions = array(
        'imageType' => 'gif'
    );

    // Draw the barcode in a new image,
    $imageResource  = Barcode::factory(
        'code39', 'image', $barcodeOptions, $rendererOptions
    )->draw();

When I var_dump $imageResource I get:

"resource(459) of type (gd)"

When I use imagegd() I get a bunch of symbols.

Not sure I am going down the best path.

In the end I would like to run through a foreach to get an image of each barcode which I can add to a pdf.

Answer 1

There is a lot of documentation available on the ZF2 BarCode class . There you find explained how to render your bar-code to an image:

$barCode = Barcode::factory(
    'code39', 'image', $barcodeOptions, $rendererOptions
)->render();

To pass to your view you can do:

new ViewModel(array('barCode' => $barCode));
