Reading spreadsheet using PHPExcel - php

Question

I'm trying to upload a spreadsheet and read it into a MySQL database using PHPExcel.
For .xlsx files it works fine but whenever I try to upload a .ods file it throws the error: PHP Fatal error: Call to a member function getNamespaces() on a non-object in PHPExcel_1.7.9/Classes/PHPExcel/Reader/OOCalc.php on line 341
What's going wrong?
HTML Form:
<form method="post" enctype="multipart/form-data">
Upload File: <input type="file" name="spreadsheet"/>
<input type="submit" name="submit" value="Submit" />
</form>
PHP (In same file):
//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'];
}
}
}
?>

When a file is uploaded to your webserver, The file will be saved in the temporary folder of your system with a random name.
What you were trying to do was giving the actual name of the file you uploaded, But since the file was created with a random name in the tmp folder.
You will need to use tmp_name instead, Which actually point the that random named file.
Also note, in name You only have the name of the file that was uploaded and not the path,
But with tmp_name you have the actual path to the file.
See the following example of a file upload you would get.
array(
[UploadFieldName]=>array(
[name] => MyFile.jpg
[type] => image/jpeg
[tmp_name] => /tmp/php/php6hst32
[error] => UPLOAD_ERR_OK
[size] => 98174
)
)
change your code to this instead
//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'];
}
}
}
?>

In my case there was an error detecting the extension in this line
$extension = strtoupper(pathinfo($inputFile, PATHINFO_EXTENSION));
if you need to solve just check from the name parameter
$extension = strtoupper(explode(".", $_FILES['spreadsheet']['name'])[1]);
The rest is working thanks :)
