I have files stored in a mysql as blob’s how would i retrieve them as downloads.
Anyone have a suggestion
Andy
just put the right header.
e.g.
header(‘Content-Type: image/png’);
header(‘Content-Disposition: attachment; filename=“whatever.png”’);
and then put out the content of the field with echo.
I have been onto php net and had a look under headers as you suggest above. I came across this and have played about with it for a bit but I am not getting an output
[php]
<?php $file = $row['name']; while (strpos($file)==false) { $file = substr($file); // cut the first char. } header ('Content-type: application/'.$file); header('Content-Disposition: attachment; filename="'.$file.'"'); $tmp = file_get_contents($row['name']); echo $tmp; ?>[/php]
I’m not sure whether its the file type that is causing the problem. The extension is .mxp
i thougt the file itself is in the database, isn’t it?
what errors are u getting with error_reporting(E_ALL) ?
substr and strpos need 2 parameter!
the file itself is in the database. I am not getting any errors
and the $file string is echoing ok so am not losing the contents.
Its just not doing anything apart from loading hte page
heres what i have now.
[php]
$file = $row[‘content’];
header(“Content-type:application/x-mmxp”);// It will be called downloaded.pdf
header(“Content-Disposition:attachment;filename=’”.$file."’");// The PDF source is in original.pdf
readfile($file);
[/php]
The $row[‘content’] is the blob file on the database is that right.
i have no idea how ur db is looking like.
i guess u’ll need something like:
[php]header(“Content-type: application/x-mmxp”);
header(‘Content-Disposition: attachment; filename="’.addslashes($row[‘name’]).’"’);
echo $row[‘content’];[/php]
All that this does is echo the file

I tried readfile but nothing happens
The db is
id int(11) NOT NULL auto_increment,
name varchar(30) collate latin1_general_ci NOT NULL default ‘’,
type varchar(30) collate latin1_general_ci NOT NULL default ‘’,
size int(11) NOT NULL default ‘0’,
content blob NOT NULL,
PRIMARY KEY (id)
it was easier to do this
error_reporting
no output before header
Now I am confused, I cant output anything before
[php]
header(“Content-type: application/x-mmxp”);
header(‘Content-Disposition: attachment; filename="’.addslashes($row[‘name’]).’"’);
echo $row[‘content’];
[/php]
so how can I have $row[‘name’] without
[php]
$query = “SELECT * FROM extensions”;
$dw_ext = mysql_query($query, $dbcon) or die(‘Error, query failed’);
$row = mysql_fetch_assoc($dw_ext);
[/php]
before it???
of cause u cann use these lines before header, because thats not generating output to the browser.
output to the browser is generated by echo/print or by anything outside <?php ?> (even a whitespace character)
Now I get it, Thanks for your help
