Jak eksportować dane do pliku Excela za pomocą PHPExcel

Question

Pobrałem kod źródłowy z limesurvey i dodałem bibliotekę PHPExcel do mojego kodu limesurvey, aby wyeksportować dane do pliku Excela po kliknięciu łącza. Obecnie plik excel otwiera się z pewnymi niepoprawnymi danymi w nim bez żadnych problemów. Po wpisaniu informacji z ankiety muszę mieć możliwość dynamicznego dodawania danych z serwera WWW. Sprawdziłem niektóre witryny, które znalazłem, ale nie miałem dużo szczęścia. Czy ktoś może mi pomóc?

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

Answer 1

Jeśli kopiowane to bezpośrednio, a następnie:

->setCellValue('B2', Ackermann') 

powinny być

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

w odpowiedzi na pytanie:

Uzyskaj dane, które chcesz z limesurvey, i użyj setCellValue() do przechowywania tych wartości danych w komórkach, w których chcesz je przechowywać.

Przykładowy plik Quadratic.php w/testach może pomóc jako punkt wyjścia: pobiera dane z formularza wejściowego i ustawia je w komórkach w skoroszycie programu Excel.

EDIT

Niezwykle uproszczony przykład:

// 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');

Obecnie używać tej funkcji w moim projekcie po serii googlowania pobrać excel plik z 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 . '"'); 
       // Instantiate a Writer to create an OfficeOpenXML Excel .xlsx file

$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');
