Cómo exportar datos a un archivo Excel utilizando PHPExcel

Question

He tomado el código fuente de limesurvey y he agregado la biblioteca PHPExcel a mi código limesurvey para exportar datos a un archivo Excel después de hacer clic en un enlace. Actualmente, el archivo de Excel se abre con algunos datos ficticios sin problemas. Necesito poder agregar datos dinámicamente desde el servidor web después de que el usuario ingrese la información de la encuesta. He investigado algunos sitios que he encontrado pero no he tenido mucha suerte. ¿Puede alguien ayudarme?

$tablename = "questions"; //your MySQL Table Name which one you have to create excel file

Answer 1

Si ha copiado de manera directa, a continuación:

->setCellValue('B2', Ackermann') 

debería ser

->setCellValue('B2', 'Ackermann') 

En respuesta a su pregunta:

Obtenga los datos que desee de limesurvey y use setCellValue() para almacenar esos valores de datos en las celdas donde desea almacenarlos.

El archivo de ejemplo Quadratic.php en/Pruebas podría ayudar como punto de partida: se toma los datos de un formulario de entrada y lo establece a las células en un libro de Excel.

Un ejemplo muy simple:

// Create your database query 
$query = "SELECT * FROM myDataTable"; 

// Execute the database query 
$result = mysql_query($query) or die(mysql_error()); 

// Instantiate a new PHPExcel object 
$objPHPExcel = new PHPExcel(); 
// Set the active Excel worksheet to sheet 0 
$objPHPExcel->setActiveSheetIndex(0); 
// Initialise the Excel row number 
$rowCount = 1; 
// Iterate through each result from the SQL query in turn 
// We fetch each database result row into $row in turn 
while($row = mysql_fetch_array($result)){ 
    // Set cell An to the "name" column from the database (assuming you have a column called name) 
    // where n is the Excel row number (ie cell A1 in the first row) 
    $objPHPExcel->getActiveSheet()->SetCellValue('A'.$rowCount, $row['name']); 
    // Set cell Bn to the "age" column from the database (assuming you have a column called age) 
    // where n is the Excel row number (ie cell A1 in the first row) 
    $objPHPExcel->getActiveSheet()->SetCellValue('B'.$rowCount, $row['age']); 
    // Increment the Excel row counter 
    $rowCount++; 
} 

// Instantiate a Writer to create an OfficeOpenXML Excel .xlsx file 
$objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel); 
// Write the Excel file to filename some_excel_file.xlsx in the current directory 
$objWriter->save('some_excel_file.xlsx');

Usando el código existente como base

// Instantiate a new PHPExcel object 
$objPHPExcel = new PHPExcel(); 
// Set the active Excel worksheet to sheet 0 
$objPHPExcel->setActiveSheetIndex(0); 
// Initialise the Excel row number 
$rowCount = 1; 

//start of printing column names as names of MySQL fields 
$column = 'A'; 
for ($i = 1; $i < mysql_num_fields($result); $i++) 
{ 
    $objPHPExcel->getActiveSheet()->setCellValue($column.$rowCount, mysql_field_name($result,$i)); 
    $column++; 
} 
//end of adding column names 

//start while loop to get data 
$rowCount = 2; 
while($row = mysql_fetch_row($result)) 
{ 
    $column = 'A'; 
    for($j=1; $j<mysql_num_fields($result);$j++)

Actualmente uso de esta función en mi proyecto después de una serie de google para descargar Excel Archivo de instrucción SQL

// $sql = sql query e.g "select * from mytablename" 
    // $filename = name of the file to download 
     function queryToExcel($sql, $fileName = 'name.xlsx') { 
       // initialise excel column name 
       // currently limited to queries with less than 27 columns 
     $columnArray = array("A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z"); 
       // Execute the database query 
       $result = mysql_query($sql) or die(mysql_error()); 

       // Instantiate a new PHPExcel object 
       $objPHPExcel = new PHPExcel(); 
       // Set the active Excel worksheet to sheet 0 
       $objPHPExcel->setActiveSheetIndex(0); 
       // Initialise the Excel row number 
       $rowCount = 1; 
    // fetch result set column information 
       $finfo = mysqli_fetch_fields($result); 
// initialise columnlenght counter     
$columnlenght = 0; 
       foreach ($finfo as $val) { 
// set column header values     
    $objPHPExcel->getActiveSheet()->SetCellValue($columnArray[$columnlenght++] . $rowCount, $val->name); 
       } 
// make the column headers bold 
       $objPHPExcel->getActiveSheet()->getStyle($columnArray[0]."1:".$columnArray[$columnlenght]."1")->getFont()->setBold(true); 

       $rowCount++; 
       // Iterate through each result from the SQL query in turn 
       // We fetch each database result row into $row in turn 

       while ($row = mysqli_fetch_array($result, MYSQL_NUM)) { 
        for ($i = 0; $i < $columnLenght; $i++) { 
         $objPHPExcel->getActiveSheet()->SetCellValue($columnArray[$i] . $rowCount, $row[$i]); 
        } 
        $rowCount++; 
       } 
// set header information to force download 
       header('Content-type: application/vnd.ms-excel'); 
       header('Content-Disposition: attachment; filename="' . $fileName . '"');

$this->load->library('excel'); 
$file_name = 'Demo'; 
$arrHeader = array('Name', 'Mobile'); 
$arrRows = array(0=>array('Name'=>'Jayant','Mobile'=>54545), 1=>array('Name'=>'Jayant1', 'Mobile'=>44454), 2=>array('Name'=>'Jayant2','Mobile'=>111222), 3=>array('Name'=>'Jayant3', 'Mobile'=>99999)); 
$this->excel->getActiveSheet()->fromArray($arrHeader,'','A1'); 
$this->excel->getActiveSheet()->fromArray($arrRows); 
header('Content-Type: application/vnd.ms-excel'); //mime type 
header('Content-Disposition: attachment;filename="'.$file_name.'"'); //tell browser what's the file name 
header('Cache-Control: max-age=0'); //no cache 
$objWriter = PHPExcel_IOFactory::createWriter($this->excel, 'Excel5'); 
$objWriter->save('php://output');
