：PHPExcel无法加入图片

$objPHPExcel = new PHPExcel();

$objDrawing = new PHPExcel_Worksheet_Drawing();
$objPHPExcel->setActiveSheetIndex(0);
$objDrawing->setPath('D:\wwwroot\user\upimg\201460dZeETjg_1.jpg');
$objDrawing->setCoordinates("A1");
$objDrawing->setWorksheet($objPHPExcel->getActiveSheet());


返回错误：Fatal error: Uncaught exception 'PHPExcel_Exception' with message 'A PHPExcel_Worksheet has already been assigned. Drawings can only exist on one PHPExcel_Worksheet.' in D:\wwwroot\user\upimg\Classes\PHPExcel\Worksheet\BaseDrawing.php:240 Stack trace: #0 D:\wwwroot\user\upimg\xls.php(71): PHPExcel_Worksheet_BaseDrawing->setWorksheet(Object(PHPExcel_Worksheet)) #1 {main} thrown in D:\wwwroot\user\upimg\Classes\PHPExcel\Worksheet\BaseDrawing.php on line 240

回复讨论(解决方案)

你这只是片段，仅从这点是看不到问题的！
因为这个代码片段并没有错！

Uncaught exception 'Exception' with message 'A PHPExcel_Worksheet has already been assigned. Drawings can only exist on one PHPExcel_Worksheet.'
是说：一个 PHPExcel_Worksheet_Drawing 实例只能在一个单元格中存在

显然你把 $objDrawing 放到 A1 后，又放到了别处

对呀！
你的 $objDrawing = new PHPExcel_Worksheet_Drawing(); 在循环外面
而 $objDrawing->setWorksheet($objPHPExcel->getActiveSheet()); 在循环里面
你如何能保证 $objDrawing = new PHPExcel_Worksheet_Drawing(); 只被这行一次呢？
虽然是套在条件分支中的，你有如何能保证条件只成立一次呢？

你只需把 $objDrawing = new PHPExcel_Worksheet_Drawing(); 放到循环里面，一切都解决了

多谢，问题找到，但是xls文档打不开
代码修改： if(file_exists($row['nameid'].'_1.jpg')){
$objDrawing[$k] = new PHPExcel_Worksheet_Drawing();
$objDrawing[$k]->setPath($row['nameid'].'_1.jpg');
$objDrawing[$k]->setCoordinates("G".$k);
$objDrawing[$k]->setWorksheet($objPHPExcel->getActiveSheet());
}
