I've been getting different suggestions with you guys
and I appreciate it alot. I tried applying your
suggestions but it looks like I'm still having a
problem with my pdf reports.
I found this lines of codes in the fpdf class.. Maybe
this is the source of the problem...
function Output($file='',$download=false)
{
//Output PDF to file or browser
global $HTTP_ENV_VARS;
if($this->state<3)
$this->Close();
if($file=='')
{
//Send to browser
Header('Content-Type: application/pdf');
if(headers_sent())
$this->Error('Some data has already been output to
browser, can\'t send PDF file');
Header('Content-Length: '.strlen($this->buffer));
Header('Content-disposition: inline;
filename=doc.pdf');
echo $this->buffer;
}
else
{
if($download)
{
//Download file
if(isset($HTTP_ENV_VARS['HTTP_USER_AGENT']) and
strpos($HTTP_ENV_VARS['HTTP_USER_AGENT'],'MSIE 5.5'))
Header('Content-Type: application/dummy');
else
Header('Content-Type:
application/octet-stream');
if(headers_sent())
$this->Error('Some data has already been output
to
browser, can\'t send PDF file');
Header('Content-Length: '.strlen($this->buffer));
Header('Content-disposition: attachment;
filename='.$file);
echo $this->buffer;
}
else
{
//Save file locally
$f=fopen($file,'wb');
if(!$f)
$this->Error('Unable to create output file:
'.$file);
fwrite($f,$this->buffer,strlen($this->buffer));
fclose($f);
}
}
}
This function is being called at the end so I wonder
how can I can improve this part to avoid caching of
generated pdf reports.
Thank you.
