 Author: Congressus, The Netherlands
 Date: 14-05-2013
 Description A PHP class to create Sepa Direct Debit XML Files

##1. INSTALLATION

SEPA SDD requires PHP 5, no other libraries are required.

To install, copy the SEPASDD.php class to a folder on the webserver and include it as follows:

```php
require_once([path_from_webroot_to_folder]/SEPASDD.php);
```

##2. CONFIGURATION

SEPA SSD requires a config array, which is validated on initiation.
The following parameters are required:

- name:		    The name of the creditor('s organization).
- IBAN: 	    The creditor's International Bank Account Number.
- BIC:		    The creditor's Bank Identification Code.
- batch:	    Whether to process as batch or as individual transactions .
		        Allowed: true or false (MUST be boolean).
- creditor_id:	The creditor's id, contact your bank if you do not know this.
- currency:	    The currency in which the amounts are defined. 
		    Allowed: ISO 4217.

#####Note:
When setting batch to true, SEPASDD will create a batch for each Direct Debit
transaction type ("FRST","RCUR", etc). and required collection date. This
means that all "FRST" transactions with collection date 2014-01-30 will be 
grouped in a batch.

####Example:

```php
$config = array("name" => "Test",
                "IBAN" => "NL50BANK1234567890",
                "BIC" => "BANKNL2A",
                "batch" => true,
                "creditor_id" => "00000",
                "currency" => "EUR"
                );
```

##3. USAGE

###3.1 Initialization

Create an instance of the class with an configuration as such:

```php
try{
    $SEPASDD = new SEPASDD($config);
}catch(Exception $e){
    echo $e->getMessage();
}
```

###3.2 Create a payment

SEPA SDD uses the addPayment method for creating payments, it requires a payment array.
The following parameters are required:

- name:			    The debtors name.
- IBAN: 		    The debtor's International Bank Account Number.
- BIC:			    The debtor's Bank Identification Code.
- amount:		    The amount to transfer from debtor to creditor (IN CENTS).
			        Allowed: integers (NO SEPARATORS) e.g. EUR 10.00 has to be entered as 1000
- type:			    The type of Direct Debit Transaction
			        Allowed: FRST (First), RCUR (Recurring), OOFF (One Off), FNAL (Final)
- collection_date:  The date at which the amount should be collected from the debtor.
                    Allowed: ISO 8601 (YYYY-MM-DD). This date should be in the future, how far in
                             the future is dependent on the type of Direct Debit. See the definition.
- mandate_id:       The ID of the written mandate from the debtor.
- mandate_date:     The date the mandate was signed.
                    Allowed: ISO 8601 (YYYY-MM-DD). For mandates before SEPA requirements this is: 2009-11-01.
- description:      The description of the transaction.

####Example:

```php
$payment = array("name" => "Test von Testenstein",
                 "IBAN" => "NL50BANK1234567890",
                 "BIC" => "BANKNL2A",
                 "amount" => "1000",
                 "type" => "FRST",
                 "collection_date" => "2013-07-12",
                 "mandate_id" => "1234",
                 "mandate_date" => "2009-11-01",
                 "description" => "Test Transaction"
                );                
```

Then use the addPayment method to add the payment to the file:

####Example:

```php
try{
    $SEPASDD->addPayment($payment);
}catch(Exception $e){
    echo $e->getMessage();
}
```

You can use this method multiple times to add more payments.

###3.3 Save the file

To save the file, use the "save" method, this will return the XML as a string.
If you want to save to file, you have to do this yourself.

####Example:

```php
try{
    $SEPASDD->save();
}catch(Exception $e){
    echo $e->getMessage();
}
```

After this, please reinitialize the class if you want to create another file.

###3.4 Adding custom fields

SEPA SDD has a special method for adding custom fields. This method is called addCustomNode.
The required arguments are:

- parent_XPATH:     The XPATH selector of the parent.
- name:             The node/tag name.
- value:            Its value, default "".
- attr:             An array containing key => value pairs defining the attributes.

####Example:

Add the postal address for a Debtor

```php
try{
    $SEPASDD->addCustomNode("//Document/CstmrDrctDbtInitn/PmtInf[last()]/DrctDbtTxInf[last()]/Dbtr","PstlAdr");
    $SEPASDD->addCustomNode("//Document/CstmrDrctDbtInitn/PmtInf[last()]/DrctDbtTxInf[last()]/Dbtr/PstlAdr","AdrLine","Rode Weeshuisstraat 25");
    $SEPASDD->addCustomNode("//Document/CstmrDrctDbtInitn/PmtInf[last()]/DrctDbtTxInf[last()]/Dbtr/PstlAdr","AdrLine","9712 ET Groningen");
}catch(Exception $e){
    echo $e->getMessage();
}
```

Will create

```xml
<PstlAdr>
    <AdrLine>Rode Weeshuisstraat 25</AdrLine>
    <AdrLine>9712 ET Groningen</AdrLine>
</PstlAdr>
```

###3.5 Validation

To validate against the pain.008.001.02 schema definition, you can
use the validate() method. This requires the XML as string as argument.

####Example

```php
try{
    $xml = $SEPASDD->save();
    $validation = $SEPASDD->validate($xml);
    print_r($validation);
}catch(Exception $e){
    echo $e->getMessage();
}
```
