7.9.1. addAfter()

Status	public
Reference	`void addAfter(int $buffer, string $code)`

Appends the code snippet $code to the end of the specified buffer $buffer.

class Opt_Processor_Foo extends Opt_Compiler_Processor
{
    protected $_name = 'foo';
 
    public function processNode(Opt_Xml_Node $node)
    {
        $node->addAfter(Opt_Xml_Buffer::TAG_BEFORE, 'echo \'hello\';');
    } // end processNode();
} // end Opt_Processor_Foo;

To generate a PHP code with curly brackets and be sure that it is used in the correct order, we have to both this method and Opt_Xml_Buffer::addBefore(). The opening bracket must be added with the first one, and the closing with the second. There are two possible combinations:

The brackets enclose the tag, but they may appear within other brackets generated by other snippets:

$node->addAfter(Opt_Xml_Buffer::TAG_BEFORE, ' if($foo){ ');
$node->addBefore(Opt_Xml_Buffer::TAG_AFTER, ' } ');

The brackets enclose both the tag and the rest of the currently added code snippets assigned to this node:

$node->addBefore(Opt_Xml_Buffer::TAG_BEFORE, ' if($foo){ ');
$node->addAfter(Opt_Xml_Buffer::TAG_AFTER, ' } ');
