How to save data in unpublic google spreadsheet using PHP without Zend Gdata library?

Question

How can I save data in unpublic google spreadsheet in PHP without using Zend Gdata lib? I can't use Zend libs, as it's shown on google tutorials, because the php server on which I'm running the script is php v. 5.0.4. I tried to find a solution using cUrl, but I can't omit the problem with authentication when doc is unpublic. How can I do it? If anyone has attempted it, please share the solution.

Answer 1

I have found out solution using curl and by creating a form for the google's spreadsheet. For prepared spreadsheet you have to create a form, without options: Require sign-in to view this form and Automatically collect respondent's username. Then check, using f.e. firebug, the form post uri and post data and use it to following script:

#prepare post data
$fields = array('backupCache' => '',
            'entry.0.single'=>urlencode($data['name']),
            'entry.1.single'=>urlencode($data['surname']),
            'pageNumber'=>urlencode(0),   
            'submit'=>'Submit');
$fields_string = '';

foreach($fields as $key=>$value) {
  $fields_string .= $key.'='.$value.'&';
}

rtrim($fields_string,"& ");
$fields_string = substr($fields_string, 0, strlen($fields_string)-1);

$ch = curl_init();
#set curl_setopt for your preferences
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);    
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);    

curl_setopt($ch, CURLOPT_POST, count($fields));
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields_string);

#set proper form uri
curl_setopt($ch, CURLOPT_URL, $formUri);
curl_setopt($ch, CURLOPT_TIMEOUT, 120);

$res = curl_exec($ch);
curl_close($ch);

May not be the most perfect solution but it works. :)

Here is an object-oriented php class for sending data to a Google Docs Spreadsheet - http://code.google.com/p/php-form-builder-class/source/browse/trunk/includes/class.spreadsheet.php?spec=svn384&r=384

cUrl is used instead of Zend's GData lib. You can find a sample implementation below. Remember to replace the test settings ("my_google_email", "my_google_password", etc) with your specific information.

$doc = new spreadsheet();
$doc->authenticate("my_google_email", "my_google_password");
$doc->setSpreadsheet("my_spreadsheet_title");
$doc->setWorksheet("my_worksheet_title");
$my_data = array("First Name" => "John", "Last Name" => "Doe");
$doc->add($my_data);

The keys of the associative array passed to the add method need to match the column headers of the spreadsheets you're using to collect the data.

You can access the GData APIs using ordinary HTTP requests; a library just makes this easier for you. You basically just end up rewriting the bits of the library you want to use.

See the protocol documentation.
