我正在尝试上传电子表格并使用 PHPExcel将其读入MySQL数据库.

对于.xlsx文件,它工作正常,但每当我尝试上传.ods文件时,它都会抛出错误：PHP致命错误：在PHPExcel_1.7.9 / Classes / PHPExcel / Reader /中的非对象上调用成员函数getNamespaces()第341行的OOCalc.php

出了什么问题？

HTML表格：

<form method="post" enctype="multipart/form-data">
Upload File: <input type="file" name="spreadsheet"/>
<input type="submit" name="submit" value="Submit" />
</form>

PHP(在同一个文件中)：

//Check valid spreadsheet has been uploaded
if(isset($_FILES['spreadsheet'])){
if($_FILES['spreadsheet']['name']){
    if(!$_FILES['spreadsheet']['error'])
    {

        $inputFile = $_FILES['spreadsheet']['name'];
        $extension = strtoupper(pathinfo($inputFile,PATHINFO_EXTENSION));
        if($extension == 'XLSX' || $extension == 'ODS'){

            //Read spreadsheeet workbook
            try {
                 $inputFile = $_FILES['spreadsheet']['tmp_name'];
                 $inputFileType = PHPExcel_IOFactory::identify($inputFile);
                 $objReader = PHPExcel_IOFactory::createReader($inputFileType);
                 $objPHPExcel = $objReader->load($inputFile);
            } catch(Exception $e) {
                    die($e->getMessage());
            }

            //Get worksheet dimensions
            $sheet = $objPHPExcel->getSheet(0); 
            $highestRow = $sheet->getHighestRow(); 
            $highestColumn = $sheet->getHighestColumn();

            //Loop through each row of the worksheet in turn
            for ($row = 1; $row <= $highestRow; $row++){ 
                    //  Read a row of data into an array
                    $rowData = $sheet->rangeToArray('A' . $row . ':' . $highestColumn . $row,NULL,TRUE,FALSE);
                    //Insert into database
            }
        }
        else{
            echo "Please upload an XLSX or ODS file";
        }
    }
    else{
        echo $_FILES['spreadsheet']['error'];
    }
}
}

?>

将文件上载到Web服务器时,该文件将以随机名称保存在系统的临时文件夹中.

您尝试做的是给出您上传的文件的实际名称,但是因为该文件是在tmp文件夹中使用随机名称创建的.
您将需要使用tmp_name,它实际指向该随机命名文件.

另请注意,在名称中您只有上传的文件的名称而不是路径,
但是使用tmp_name,您可以获得文件的实际路径.

请参阅以下您将获得的文件上载示例.

array(
 [UploadFieldName]=>array(
    [name] => MyFile.jpg
    [type] => image/jpeg
    [tmp_name] => /tmp/php/php6hst32
    [error] => UPLOAD_ERR_OK
    [size] => 98174
  )
)

将代码更改为此代码

//Check valid spreadsheet has been uploaded
if(isset($_FILES['spreadsheet'])){
if($_FILES['spreadsheet']['tmp_name']){
if(!$_FILES['spreadsheet']['error'])
{

    $inputFile = $_FILES['spreadsheet']['tmp_name'];
    $extension = strtoupper(pathinfo($inputFile,PATHINFO_EXTENSION));
    if($extension == 'XLSX' || $extension == 'ODS'){

        //Read spreadsheeet workbook
        try {
             $inputFileType = PHPExcel_IOFactory::identify($inputFile);
             $objReader = PHPExcel_IOFactory::createReader($inputFileType);
                 $objPHPExcel = $objReader->load($inputFile);
        } catch(Exception $e) {
                die($e->getMessage());
        }

        //Get worksheet dimensions
        $sheet = $objPHPExcel->getSheet(0); 
        $highestRow = $sheet->getHighestRow(); 
        $highestColumn = $sheet->getHighestColumn();

        //Loop through each row of the worksheet in turn
        for ($row = 1; $row <= $highestRow; $row++){ 
                //  Read a row of data into an array
                $rowData = $sheet->rangeToArray('A' . $row . ':' . $highestColumn . $row,FALSE);
                //Insert into database
        }
    }
    else{
        echo "Please upload an XLSX or ODS file";
    }
}
else{
    echo $_FILES['spreadsheet']['error'];
}
}
}

?>
