=== Frequently Asked Questions ===

= How do I create my own export format? =

First, register your Export Format with the plugin like so:

<?php
add_filter( 'jmb_pf_plugin_settings', function( $settings ) {
	$settings['export_formats']['text_2'] = array(
		'name'     => 'Text 2',
		'ext'      => '-text-2.txt',
		'callback' => 'jmb_pf_text_2_format',
	);

	return $settings;
});
?>

Then create the Export Function that takes the feed data and exports it to a file, like so:

<?php
function jmb_pf_text_2_format( $args = array() ) {
	$a = array_merge( array( 
		'file_name' => '',
		'posts'     => array(),
	), $args );

	if ( empty( $a['posts'] ) ) {
		return;
	}

	$text_content = '';

	foreach ( $a['posts'] as $post ) {
		if ( ! empty( $text_content ) ) {
			$text_content .= "\n";
		}

		foreach ( $post as $data_name => $data_value ) {
			$text_content .= sprintf( "%s ", $data_value );
		}
	}

	if ( ! empty( $a['file_name'] ) ) {
		$fp = fopen( $a['file_name'], 'w' );
		fputs( $fp, $text_content );
		fclose( $fp );

		return true;
	}

	return $text_content;
}
?>
