无法保存cakephp中excel的循环数据

$inputFileName = $_FILES["file"]["tmp_name"]; $objReader = PHPExcel_IOFactory::createReader('Excel5'); $objReader->setReadDataOnly(true); $objPHPExcel = $objReader->load($inputFileName); $objWorksheet = $objPHPExcel->getActiveSheet(); $highestRow = $objWorksheet->getHighestRow(); // eg 10 $highestColumn = $objWorksheet->getHighestColumn(); // eg 'F' $highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn); // eg 5 $Player_name = ''; $Activity_name = ''; $Domain_id = ''; $Activity_description = ''; $Activity_date; $player_id_owner = ''; $DomainCount = ''; echo '<table>' .

我有一个从excel文件中读取并保存域，活动和播放器的函数。 当excel文件只包含1行时，它运行良好，但如果excel包含多个文件，只有最后一行保存，但所有行的所有行都保存，我试图debugging它，我回声每一个循环，它读取所有的行，我试图在保存方法后插入一个回声，以知道它是否成功，它的工作原理，但是当我在数据库中检查，只有最后一行被保存，但活动都保存。 请帮助我，谢谢。

使用$ this-> Activity-> clear（）重置模型。

正如CakePHP书中所述 ：

在循环中调用保存时，不要忘记调用clear（）。

clear方法在保存数据之前重置模型。 如果不使用clear() ，则保存的行的ID仍在模型中，因此下一次保存的调用save覆盖先前保存的行。

有关clear方法，请参阅CakePHP书籍 ：

此方法可用于重置模型状态并清除未保存的数据和validation错误。
