Warning: Cannot modify header information

Post your code again after masking the password, and applying [php] tags.

Now you have disordered line 18 and 71, the actual culprits.

Hi,

The headers have to be set before any output is given. Output includes blank lines in the file. you can process information before the headers are set you just can't write anything to the screen.

Perhaps that's the problem.

Cheers

Nor can I but I'm guessing there something in the code that was left out.

Perhaps you could post the full code sample, using tags, but simply change the sesitive data to indicate what shuold be there.

NO!!! Its not an image file!

Instead of <? header("Content-type: image/jpeg");echo $rows['image']; ?>, write <img src="<?php echo $rows['image']; ?>"></img>

**hsriat** · Mar 1 '08, 06:22 AM

*If $rows['image'] referrers to the name of the image file.

Look at post #8

And dont type in caps.

**ronverdonk** · Mar 2 '08, 02:05 PM

Don't overdo you tags now. Just one pair at start and end of your code suffices.
