Generating files on the fly

[press711]

Can any one direct me to any articles of information on creating temporary files on the fly.
I tried searching for it but did'nt get much.
I need to allow my customers to click on a button and the script should create a file, which is attached and send to the users database. The file is a iif file for quickbooks. I dont want to store the file just send it as a attachment.

Thanks,
Kunal 🙂

I'm not sure what you are asking.

Attached? Attached to what?

Send to the users database?

If you are just writing data to a database, what do you need a file for?

Or if you need a "temporary" file, just write a file, then erase it. I guess that would make it temporary.

I'm just amending someone else's code to do that at the moment.

function out($fptr,$s)  

{  

    if ($fptr==false) echo("$s"); 
	else fputs($fptr,$s);  

} 

function mysqlbackup($host,$dbname, $uid, $pwd, $output, $structure_only)  

{  

//from [url]http://codewalkers.com/seecode/46.html[/url]
	$sendSave = false;
    if (strval($output)!="")
	{
	  if ($output == "email") 
	  {
	    $fptr = fopen("bup/bupemail.txt","w");
		$sendSave = true;
	  }
	  else $fptr=fopen($output,"w"); 
	}
	else $fptr=false;  


// lots more code which calls a function called out() - see above

//close the file if we aren't echoing   
if ($fptr!=false) 
{
  fclose($fptr);  
  // do we need to email it?
  if ($sendSave == true)
  {
    include('includes/class.html.mime.mail.inc');

  $mail = new html_mime_mail('X-Mailer: Html Mime Mail Class');
  $body = "<h3>Attachment</h3><p>MySite</p></body></html>";
  $text = strip_tags ($body , "a");

  $attachment = fread($fp = fopen($fptr, 'r'), filesize($fname));
  fclose($fp);

  $mail->add_html($body, $text);

  $mail->set_charset('iso-8859-1', TRUE);
  $mail->add_attachment($attachment, $filename, 'application/octet-stream');
  $mail->build_message();
  $email = "[e-mail]";
  $mail->send($email, $email, 'MySite', $email, $filename . " from [url]http://www.mysite.com[/url]");
  //should also delete the file! here, code to be written
  }//end of email file check
}//end of close file check

I haven't put the delete bit in yet but once it's attached it can be deleted. I haven't finished testing either.

good luck

Thanks I hope that works

Two things to change, put a wait in to allow the file to finish writing before I sent it, see my thread at http://www.phpbuilder.com/board/showthread.php?threadid=10224911&goto=newpost

then Ihad to delete the file before creating a new file. So used a function I got from http://www.php.net and called it fdelete() because that seemed like a sensible name to me 🙂

function fdelete($file) 
{ 
  $delete = @unlink($file); 
  if (@file_exists($file)) 
  { 
    $filesys = eregi_replace("/","\\",$file); 
    $delete = @system("del $filesys"); 
    if (@file_exists($file)) 
	{ 
      $delete = @chmod ($file, 0775); 
      $delete = @unlink($file); 
      $delete = @system("del $filesys");
	}
  }
}//fdelete

Hi Sarah,

Instead of creating a temporary file. I am directly storing the file in a variable $mynewattach, and adding the content using the command below.

I think you are also using the same class.

$mail->addAttachment($mynewattach, 'kunal.iif', 'application/iif');

This seems to work well for me as I dont need to depend on a server folder and creating temporary files, with dangers of two transaction taking place at the same time and hence two files overwriting each other.

Thanks for your help and time. 🙂

Best Regards,
