Hi, i’m having problems retrieving my images. They’re in a mysql database, and i want to display them on my webpage. The problem is whenever i try to use a header to set the content type, i run into the “header already set” error. I just want to change the header for one line so i can display the image with an echo command, how do i do this?
You must send headers before any other output.
header() has to be the first thing that gets outputted to the browser.
u have output before u use the hader function.
make sure there is nothing (not even withspace) before ‘<?php’.
and move the header that far to the begining of ur script that there is no echo or print before the header function.
but i need other output before i add the image, am i still going to be able to output normal HTML stuff if i set the header to image earlier?
to clarify - what i need is a legal way to do<?php echo('text content') header('Content-Type: image/jpeg'); echo($image_binary_variable) echo('more text content') ?>
You can use:
echo(‘more text content’);
u cant output both an image and html.
if u are using the same file u have to have an indicator whethere it is outputing the image or the html. then u can use an if to have no output if it is an image.
