How to upload presentation file into Google Slides using PHP? - api

Question

How can I upload presentation file (ppt, pptx, pdf) to Google Slides service using PHP.
I didn't find an example in these links:
https://developers.google.com/slides/quickstart/php
https://developers.google.com/api-client-library/php/support
My code:
$service = new Google_Service_Drive($client);
$fileMetadata = new Google_Service_Drive_DriveFile([
'name' => 'My Presentation',
'mimeType' => 'application/vnd.google-apps.presentation',
// 'mimeType' => 'application/vnd.google-apps.document',
]);
$file = $service->files->create($fileMetadata, [
'data' => file_get_contents(realpath(dirname(__FILE__)) . '/Modelo_Slide_Padrao.pptx'),
// 'mimeType' => 'application/vnd.ms-powerpoint', // 'application/pdf',
'uploadType' => 'multipart',
'fields' => 'id',
]);
printf("File ID: %s\n", $file->id);
Somebody help me?
Thank you.

You cannot upload a presentation file to Google Slides. What you are required to do is to import the file to Google Drive using a Google Doc Type. Take a look at the reference documentation which has an example of how to achieve this. Here are the examples of how to achieve what you need.
PPT to Google Slides Presentation:
$service = new Google_Service_Drive($client);
// Create a new file
$file = new Google_Service_Drive_DriveFile(array(
'name' => 'PPT Test Presentation',
'mimeType' => 'application/vnd.google-apps.presentation'
));
// Read power point ppt file
$ppt = file_get_contents("SamplePPT.ppt");
// Declare optional parameters
$optParams = array(
'uploadType' => 'multipart',
'data' => $ppt,
'mimeType' => 'application/vnd.ms-powerpoint'
);
// Import pptx file as a Google Slide presentation
$createdFile = $service->files->create($file, $optParams);
// Print google slides id
print "File id: " . $createdFile->id;
PPTX to Google Slides Presentation:
$service = new Google_Service_Drive($client);
// Create a new file
$file = new Google_Service_Drive_DriveFile(array(
'name' => 'PPTX Test Presentation',
'mimeType' => 'application/vnd.google-apps.presentation'
));
// Read Powerpoint pptx file
$pptx = file_get_contents("SamplePPTX.pptx");
// Declare opts params
$optParams = array(
'uploadType' => 'multipart',
'data' => $pptx,
'mimeType' => 'application/vnd.openxmlformats-officedocument.presentationml.presentation'
);
// Import pptx file as a Google Slide presentation
$createdFile = $service->files->create($file, $optParams);
// Print google slides id
print "File id: " . $createdFile->id;
PDF to Google Document Doc: (is not possible to Google Slide Presentation)
$service = new Google_Service_Drive($client);
// Create a new file
$file = new Google_Service_Drive_DriveFile(array(
'name' => 'PDF Test Document',
'mimeType' => 'application/vnd.google-apps.document'
));
// Read pdf file
$pdf = file_get_contents("SamplePDF.pdf");
// Declare opts params
$optParams = array(
'uploadType' => 'multipart',
'data' => $pdf,
'mimeType' => 'application/pdf'
);
// Import pdf file as a Google Document File
$createdFile = $service->files->create($file, $optParams);
// Print google document id
print "File id: " . $createdFile->id;
The only thing that changes in each code snippet is the mimeType. For a reference of Mime Types you can visit here and for a reference of Google Mime Types you can visit here.
