Headers

Anon

Hi people,
I am having a problem with php. When I select an image in a database and I try show this image I receive this message:
Cannot add header information - headers already sent by (output started at c:\projeto\front-end\exame.php:2) in c:\projeto\front-end\exame.php on line 2

See the source:

<pre>
<body background="fundo3.gif" text="#000000">
<p align="center"><font face="Comic Sans MS" color="#005E5E"><big>Dados do Exame</big></font></p>

<?
Header("Content-type:image/jpg");

// conect to BD
$conn = OCILogon("XXX", "YYY', "KKKK");

$conimg = OCIParse( $conn, "Select img from testeimg where id = 1");
OCIExecute( $conimg );
$k = 1;
while( OCIFetch( $conimg ))
//receive datas of select
$imagem = OCIResult( $conimg, $k );

print "$imagem";
OCILogoff( $conn );
?>

</body>
</pre>

Can anybody help me please?

Hi,

What youve donw is printed output before youve sent out the gheader. You cant print output to the browser until youve sent out your headers. Just put the header at the top of your code.

You cannot add headers after the body has started. That's why it's called a header.

And putting an image directly into a page is never gonna happen man... never.
Guess you skipped HTML 101 the day the teacher explained just what HTML really was.

You need to have a second file to display that image and feed the appropriate header BEFORE you dump the blob from the DB result.

The file will be referenced by the script you gave in your example via a plain ol <img> tag, you can throw a row id at it say... <img src="/img_get.php?id=101"> and then your img_get.php file could query for rowID 101 and fetch the image for display.
