CodeIgniter vCard Library to Export Vcard .VCF files with Zip Support

Posted by Carlos

The Vcard.php Library Code (applications/library/Vcard.php) :

Then we can use it on a controller function like this:

The vcard function on the controller calls the library Vcard.php and then use the constructor, for that you have to arrange an array of COMMON VALUES for, we can use the Troy example for this:

You can customize the $datavcard array to suit your contact information and then passit to the constructor like the function before.

I hope this would be quite enough for this to get work on export vCards.

Thanks for your comments,

Carlos

PS. The Codeigniter Wiki for this library is here: vCard Library

Codeigniter SimpleXML data parser with Table View

Posted by Carlos

I read about the SimpleXML library from this blog SimpleXML Library, but this time, I mafe some changes to make the MVC concepts on the table view and xmltest controller best fit.

First we load the Simplexml library to applications/library on codeigniter:

result="";
	$this->evalCode="";
	$values="";
	$encoding = 'UTF-8';
	$parser = xml_parser_create($encoding);
	xml_parser_set_option($parser, XML_OPTION_CASE_FOLDING, 0);
	xml_parser_set_option($parser, XML_OPTION_SKIP_WHITE, 1);
	$ok = xml_parse_into_struct($parser, $data, $values);
	if (!$ok) {
		$errmsg = sprintf("XML parse error %d '%s' at line %d, column %d (byte index %d)",
		xml_get_error_code($parser),
		xml_error_string(xml_get_error_code($parser)),
		xml_get_current_line_number($parser),
		xml_get_current_column_number($parser),
		xml_get_current_byte_index($parser));
	}

	xml_parser_free($parser);
	return $this->xml_reorganize($values);
	}

	function xml_reorganize($array)
	{

		$count = count($array);

		$repeatedone = false;
		$tags = array();
		$k = 0;
		for ($i = 0; $i < $count; $i++) {
			switch ($array[$i]['type']) {
				case 'open':
					array_push($tags, $array[$i]['tag']);
					if ($i > 0 && ($array[$i]['tag'] == $array[$i-1]['tag']) && ($array[$i-1]['type'] == 'close'))
					$k++;
					if (isset($array[$i]['value']) && ($array[$i]['value'] || !$this->skip_empty_values)) {
						array_push($tags, '@content');
						$this->array_insert(count($tags), $tags, $array[$i]['value'], "open");
						array_pop($tags);
					}

					if (in_array($array[$i]['tag'] . $array[$i]['level'], $repeat)) {

							array_pop($tags);
						}
					}
					break;

				case 'complete':
					array_push($tags, $array[$i]['tag']);
					if (in_array($array[$i]['tag'] . $array[$i]['level'], $repeat)) {

The xmltest.php controller for codeigniter (applications/controller/xmltest.php):

load->library('parser');
		$this->load->library('simplexml');

		$filename = 'myxml.xml';
		$xmlfile="./xml/".$filename;
		$xmlRaw = file_get_contents($xmlfile);
		$data['xmlData'] = $this->simplexml->xml_parse($xmlRaw);
		//$this->parser->parse('xml/table_view', $data);
		echo $this->load->view('xml/table_view', $data, TRUE);
	}
}

/* End of file xmltest.php */
/* Location: ./system/application/controllers/xmltest.php */

At last but not least the table view on codeigniter (applications/views/xml/table_view) with foreach on xml row items:

';
		foreach($row as $item => $value)
		{
			//could be $value instead of $row[$item], but this show the array manipulation in the foreach
			$result .= '


';
		}
		$result .= '

';
	}
	echo $result;
?>
	



PRODUCT ID
PRODUCT NAME
CATEGORY
PRICE



'.$row[$item].'

And the Jquery AddClass for even class on rows:

Thanks for your comments, the next wave would be the MySQL insert function on the xmltest controller.
