Autogiro specifications

This library is developed against the technichal manual (in swedish) of the direct debit system (autogirot) revised 2016-12-13. For later versions of this document see Bankgirocentralen.

Generating autogiro request files

Create a writer by supplying your bankgiro account number and BGC customer number to WriterFactory.

$writer = (new \byrokrat\autogiro\Writer\WriterFactory)->createWriter(
    '123456',
    (new \byrokrat\banking\BankgiroFactory)->createAccount('1111-1119')
);

Perform actions on the writer and generate file.

$writer->deleteMandate('1234567890');
$rawFile = $writer->getContent();
echo $rawFile;

Will output something like:

0120180114AUTOGIRO                                            1234560011111119  
0300111111190000001234567890                                                    

Parsing autogiro files

Create a parser using the ParserFactory.

$factory = new \byrokrat\autogiro\Parser\ParserFactory;
$parser = $factory->createParser();

The created parser will by default parse and validate monetary amounts, account numbers and identification numbers. Opt out of this functionality by using one of the visitor constants:

$factory->createParser(\byrokrat\autogiro\Parser\ParserFactory::VISITOR_IGNORE_OBJECTS);

Parsing a file creates a node object.

use byrokrat\autogiro\Tree\Node;

/** @var Node */
$node = $parser->parse($rawFile);

Accessing special objects

Account, Amount, StateId and Date nodes are nested structures, where child node Object contains constructed php objects. Access using something like:

$money = $node->getChild(Node::AMOUNT)->getObjectValue();

Walking the parse tree

A simpler way of doing this is by using visitors. See below.

Walk the tree by calling hasChild(), getChild() and getChildren().

echo $node->getChild(Node::MANDATE_REQUEST_SECTION)
    ->getChild(Node::DELETE_MANDATE_REQUEST)
    ->getChild(Node::PAYER_NUMBER)
    ->getValue();

Or access all Node::DELETE_MANDATE_REQUEST nodes.

$mandateRequests = $node->getChild(Node::MANDATE_REQUEST_SECTION);

foreach ($mandateRequests->getChildren(Node::DELETE_MANDATE_REQUEST) as $deleteRequest) {
    // process...
}

Trying to access a child that does not exist returns a NullNode.

echo $node->getChild('this-does-not-exist')
    ->getChild('and-neither-does-this')
    ->isNull();

Accessing nodes using visitors

With the use of visitors nodes can be accessed based on name or type.

class MyVisitor extends \byrokrat\autogiro\Visitor\Visitor {
    function beforeDeleteMandateRequest($node) {
        echo "Delete mandate request found!";
    }
}

$visitor = new MyVisitor;

$node->accept($visitor);

This can also be done dynamically.

$visitor = new \byrokrat\autogiro\Visitor\Visitor;

$visitor->before(Node::DELETE_MANDATE_REQUEST, function ($node) {
    echo "Delete mandate request found!";
});

Finding mandate responses

$visitor->before(Node::MANDATE_RESPONSE, function ($node) {
    if ($node->hasChild(Node::CREATED_FLAG)) {
        // Mandate successfully created
    }
    if ($node->hasChild(Node::DELETED_FLAG)) {
        // Mandate successfully deleted
    }
    if ($node->hasChild(Node::ERROR_FLAG)) {
        // Mandate error state
    }
});

Finding payment responses

$visitor->before(Node::SUCCESSFUL_INCOMING_PAYMENT_RESPONSE, function ($node) {
    // successfull payment..
});

$visitor->before(Node::FAILED_INCOMING_PAYMENT_RESPONSE, function ($node) {
    // failed payment..
});

Generating XML from node trees

Using this feature can be very helpful to understand how the parser interprets various layouts.

$xmlWriter = (new \byrokrat\autogiro\Xml\XmlWriterFactory)->createXmlWriter();

echo $xmlWriter->asXml(
    $parser->parse($rawFile)
);

Hacking

With composer installed as composer

make

Or use something like

make COMPOSER_CMD=./composer.phar
