Sorry for my bad English.
this library has the function of generating xml, csv and html table from a query in the database.
Code:
<?php
/**
* Biblioteca responsável por gerar uma tabela com os resultados do banco de dados.
* @author Carlos Lorenzon
*/
class DataRender {
private $query;
/**
* Method returns the result of a query in an html table.<br />
* Customize the look by adding to your CSS class name <b>datatable</b>.
* @param query $query query database
* @param array $tableData column names from the database
* @param array $tableHeader column names header to data Table
* @param string $class class table html
* @param string $trParam parameters to TR html table (ex: javascript, id)
* @param string $tdParam parameters to TD html table (ex: javascript, id)
* @return string Table with the results
*/
public function dataTable($query, $tableData, $tableHeader = 0, $class="datatable", $trParam="", $tdParam="") {
if ($query->num_rows() > 0) {
$CI = & get_instance();
$CI->load->helper('string');
$retorno = '<table class="'.$class.'"><tr>';
if (($tableHeader != 0) and (count($tableData) == count($tableHeader))) {
foreach ($tableHeader as $th) {
$retorno.= "<th>$th</th>";
}
} else {
foreach ($tableData as $th) {
$retorno.= "<th>$th</th>";
}
}
$retorno.= "</tr>";
foreach ($query->result() as $row) {
$classTd = alternator('class="odd"', 'class="even"');
$retorno.= "<tr $trParam>";
foreach ($tableData as $td) {
$retorno.= "<td $classTd $tdParam>" . $row->$td . "</td>";
}
$retorno.= "</tr>";
}
$retorno.="</table>";
} else {
$retorno = "Não existem registros a serem apresentados";
}
return $retorno;
}
/**
* Method returns the result of a query in an xml string.<br />
* @param query $query query database
* @param string $root root element xml
* @param string $element element xml
* @return string xml with the results
*/
public function xml($query, $root="root",$element="element") {
if ($query->num_rows() > 0) {
$CI = & get_instance();
$CI->load->dbutil();
$config = array (
'root' => $root,
'element' => $element,
'newline' => "\n",
'tab' => "\t"
);
$xml = $CI->dbutil->xml_from_result($query, $config);
return $xml;
}
}
/**
* Method returns the result of a query in an csv string.<br />
* @param query $query query database
* @param array $tableData column names from the database
* @param string $separetor separator csv
* @return string csv with the results
*/
public function csv($query, $tableData, $separator=";") {
if ($query->num_rows() > 0) {
$retorno = "";
foreach ($query->result() as $row) {
foreach ($tableData as $td) {
$retorno.= str_replace($separator ,'', $row->$td ) . $separator;
}
$retorno.= "\n";
}
}
return $retorno;
}
}
?>
Method of use:
Code:
$this->load->library('datarender');
$query = $this->db->get('table-name');
$dataRender = new DataRender();
//to html table
$conteudo = $dataRender->dataTable($query, array('column-name-DB', 'column-name-DB'), array('column-name-Table','column-name-Table'));
//If you do not fill in the name of the columns for the html pick the name of the database columns
// to xml
$xml = $dataRender->xml($query, "Configuracoes", "Configuracao");
//to csv
$csv = $dataRender->csv($query,array('value'));
Hope you enjoy and look forward suggestions
