Hi Dave and thanks for advice.
You show in your example how to create an html file containing only
one picture.
How do you insert multiple graphical images into a "mixed" document
containing text and graphical images?
Do I still have to save bytea data into a temporary file (how?) and
than get in with <img> tag?
Sorry for stupid questions :-)
Mike
Are there any other ways to export images from the database?
Hi Mike,
I store them in bytea columns, along with their mimetype, then use a
script like:
<?php
require "db.php";
$sql = "SELECT image_data, image_mimetype FROM images where id = " .
intval($_GET['id']);
$res = pg_query($GLOBALS['db'], $sql);
if (pg_numrows($res) != 1)
{
header("HTTP/1.0 404 Not Found");
exit();
}
$image = pg_unescape_bytea(pg_result($res, 0, 0));
$mimetype = pg_result($res, 0, 1);
header("Expires: " . date("D, j M Y H:i:s", time() + (86400)) . " UTC");
header("Cache-Control: Public");
header("Pragma: Public");
header("Content-Type: " . $mimetype);
echo $image;
?>
I should really rewrite that to use a parameterized query, but you get
the idea :-)
Regards, Dave
