So exportieren Sie Daten in eine Excel-Datei mit PHPExcel

Question

Ich habe den Quellcode von Limesurvey genommen und die PHPExcel-Bibliothek zu meinem Limesurvey-Code hinzugefügt, um Daten in eine Excel-Datei zu exportieren, nachdem Sie auf einen Link klicken. Derzeit öffnet die Excel-Datei mit einigen Dummy-Daten in es problemlos. Ich muss in der Lage sein, dynamisch Daten vom Webserver hinzuzufügen, nachdem ein Benutzer Umfrageinformation eingibt. Ich habe mir einige Seiten angesehen, die ich gefunden habe, aber ich hatte nicht viel Glück. Kann mir jemand helfen?

<?php 
$dbhost= "mysql"; //your MySQL Server 
$dbuser = "survey"; //your MySQL User Name 
$dbpass = "password"; //your MySQL Password 
$dbname = "database"; 
//your MySQL Database Name of which database to use this 
$tablename = "questions"; //your MySQL Table Name which one you have to create excel file 
// your mysql query here , we can edit this for your requirement

Answer 1

Wenn Sie diese direkt kopiert haben, dann:

->setCellValue('B2', Ackermann') 

sollte auf Ihre Frage

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

In Antwort:

Holen Sie sich die gewünschten Daten von limesurvey und verwenden Sie setCellValue(), um diese Datenwerte in den Zellen zu speichern, in denen Sie sie speichern möchten.

Die Datei Quadratic.php Beispiel in/Tests könnte als Ausgangspunkt helfen: Es nimmt Daten von einer Eingabemaske und legt es an den Zellen in einem Excel-Arbeitsbuch.

EDIT

Ein extrem einfaches Beispiel:

// 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');

ich derzeit diese Funktion in meinem Projekt verwenden nach einer Reihe von googeln Excel-Datei von SQL-Anweisung

// $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'); 
$objWriter->save('php://output');
