php - 使用 PHPExcel 读取电子表格

Question

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 fatal error :在 PHPExcel_1.7.9/Classes/PHPExcel 中的非对象上调用成员函数 getNamespaces()/Reader/OOCalc.php 第 341 行

出了什么问题？

HTML 格式:

<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'];
    }
}
}

当文件上传到您的网络服务器时，该文件将以随机名称保存在您系统的临时文件夹中。

您尝试做的是提供您上传文件的实际名称，但由于该文件是在 tmp 文件夹中使用随机名称创建的。您将需要改用 tmp_name，它实际上指向那个随机命名的文件。

另请注意，在 name 中，您只有上传文件的名称，而没有路径，但是使用 tmp_name，您就有了文件的实际路径。

请参阅以下文件上传示例。

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

改成你的代码

 //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, NULL, TRUE, FALSE);
                //Insert into database
        }
    }
    else{
        echo "Please upload an XLSX or ODS file";
    }
}
else{
    echo $_FILES['spreadsheet']['error'];
}
}
}
