Próbowałem wyeksportować dane do pliku Excel z numerem QRcode w komórce. Podgasłem i spróbowałem oszukać.

Wreszcie pomyśleliśmy o dodaniu przykładowego pliku obrazu. następnie z plikiem obrazu phpqrcode.

Wciąż nie udało się, proszę, pomóż mi.

Kod:

/** Error reporting */ 
error_reporting(E_ALL); 
ini_set('display_errors', TRUE); 
ini_set('display_startup_errors', TRUE); 
date_default_timezone_set('Europe/London'); 

if (PHP_SAPI == 'cli') 
    die('This example should only be run from a Web Browser'); 

/** Include PHPExcel */ 
require_once dirname(__FILE__) . '/Classes/PHPExcel.php'; 


// Create new PHPExcel object 
$objPHPExcel = new PHPExcel(); 

$gdImage = imagecreatefromjpeg('abstract_bg.jpg'); 
//Add a drawing to the worksheet 
echo date('H:i:s') . " Add a drawing to the worksheet\n"; 
$objDrawing = new PHPExcel_Worksheet_MemoryDrawing(); 
$objDrawing->setName('Sample image');$objDrawing->setDescription('Sample image'); 
$objDrawing->setImageResource($gdImage); 
$objDrawing->setRenderingFunction(PHPExcel_Worksheet_MemoryDrawing::RENDERING_JPEG); 
$objDrawing->setMimeType(PHPExcel_Worksheet_MemoryDrawing::MIMETYPE_DEFAULT); 
$objDrawing->setHeight(150); 
$objDrawing->setWorksheet($objPHPExcel->getActiveSheet()); 
//$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');$objWriter->save(str_replace('.php', '.xlsx', __FILE__)); 

// Set document properties 
$objPHPExcel->getProperties()->setCreator("Jimson Jose") 
          ->setLastModifiedBy("Jimson Jose") 
          ->setTitle("Office 2007 XLSX Test Document") 
          ->setSubject("Office 2007 XLSX Test Document")

          ->setKeywords("office 2007 openxml php") 
          ->setCategory("Rewards"); 


// Add some data

Podczas generowania pliku, należy dokonać żadnego wyjścia debugowania jak

echo date('H:i:s') . " Add a drawing to the worksheet\n"; 

ponieważ psuje wyjścia binarnego.

Jeśli usuniesz ten wiersz, twój kod będzie działał.

<?php 
/** Error reporting */ 
error_reporting(E_ALL); 
ini_set('display_errors', TRUE); 
ini_set('display_startup_errors', TRUE); 
date_default_timezone_set('Europe/London'); 

if (PHP_SAPI == 'cli') 
    die('This example should only be run from a Web Browser'); 

/** Include PHPExcel */ 
require_once dirname(__FILE__) . '/Classes/PHPExcel.php'; 


// Create new PHPExcel object 
$objPHPExcel = new PHPExcel(); 

$gdImage = imagecreatefromjpeg('abstract_bg.jpg'); 
//Add a drawing to the worksheet 

$objDrawing = new PHPExcel_Worksheet_MemoryDrawing(); 
$objDrawing->setName('Sample image');$objDrawing->setDescription('Sample image'); 
$objDrawing->setImageResource($gdImage); 
$objDrawing->setRenderingFunction(PHPExcel_Worksheet_MemoryDrawing::RENDERING_JPEG); 
$objDrawing->setMimeType(PHPExcel_Worksheet_MemoryDrawing::MIMETYPE_DEFAULT); 
$objDrawing->setHeight(150); 
$objDrawing->setWorksheet($objPHPExcel->getActiveSheet()); 
//$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');$objWriter->save(str_replace('.php', '.xlsx', __FILE__)); 

// Set document properties 
$objPHPExcel->getProperties()->setCreator("Jimson Jose") 
          ->setLastModifiedBy("Jimson Jose") 
          ->setTitle("Office 2007 XLSX Test Document") 
          ->setSubject("Office 2007 XLSX Test Document") 
          ->setDescription("For minimizing work force by jimson, generated using PHP classes.") 
          ->setKeywords("office 2007 openxml php") 
          ->setCategory("Rewards"); 


// Add some data 
$objPHPExcel->setActiveSheetIndex(0) 
      ->setCellValue('A1', 'Hello') 
      ->setCellValue('B2', 'world!') 
      ->setCellValue('C1', 'Hello')

Polecam również usuwanie raportów z tego skryptu błąd:

/** Error reporting */ 
error_reporting(E_ALL); 
ini_set('display_errors', TRUE); 
ini_set('display_startup_errors', TRUE);
