buffer help please

[jake2891]

Hi guys i have a pdf library that im using to generate pdf's from html. Im calling a function thats builds the html and using buffer to return the html to the pdf script. The problem is that when it runs it says the file type is missing or unsupported. Can anyone see if im using the ob_start and ob_get_flush functions correctly in my code below thanks.

 

The pdf part

 

                        if($_REQUEST['propertyIDs'] != '') {

                          $propertyIDs = explode("|",$_REQUEST['propertyIDs']);

                          foreach ($propertyIDs as $value) {

                              if($value != '') {

                              $html .= draw_property_summary($value);  //calls the function that gets the html 

                              }

                          }

                        }

                       

                        $old_limit = ini_set("memory_limit", "16M");

                        $dompdf = new DOMPDF();

                        $dompdf->load_html($html);

                        $dompdf->set_paper('letter', 'portrait');

                        $dompdf->render();

                        $dompdf->stream("dompdf_out.pdf");

                        exit(0);

 

The draw_property_summary function /* The problem part */

 

function draw_property_summary($propertyID, $r='') {

ob_start();

 

 

if($r=='') {

$department = property_department($propertyID);

$sql = "/*  select of fields here etc..  */";

$r = wrapped_query_r_get_row($sql);

}

 

$image_query= "select fileds here";

$image_result= mysql_query($image_query) or die(mysql_error());

if($image_result = wrapped_query_r_get_assoc($image_query)){

foreach ($image_result as $image_row){

$imagePath= $image_row['imageURL'].$image_row['propertyID'].'_'.$image_row['imageName'].'_large.jpg';

$img_url = $imagePath;

}

}

else {

$img_url = false;

}

 

list($postcode,$foo) = split(" ", $r['p_postcode']);

$address_line = join_nonempty(", ", array($r['p_street'], $r['p_address4'] . " ".$postcode));
