Direct HTTP response from a module

[matt]

All,

I wan't to implement a module, that can store images in the database and display them in tags. The only way I know to do that is to store base64 encoded images, load them, decode and send as an HTTP response when browser requests URL from the tag.

Like this:

Code: Select all

header("Content-type: ".$record['type']);
header("Content-length: ".$record['size']);
header("Content-Disposition: attachment; filename=".$record['name']);
header("Content-Description: Attachment");
echo base64_decode($record['content']);

Where $record is a db row.

Is there a way to do it from a module? Because as far as I know modules only insert their content into a template. How to send just this HTTP response?

Alternatively - what would be the best place in CMSMS to implement such a response while at the same time using the db connection or any other required stuff already in CMSMS?

Thanks,
Matt.

The Uploads module does similar things to send files to people, you can do a search through this for "header" tags for a reference.

Hi Matt,

I once started developing a module to list employees. One of the fields was a picture of the person.
The picture was stored in the DB as a blob and then a PHP file generated the image in an IMG tag.

Install the attached module and see if you can use something here (In the Admin it shows up under content, I think).

The module is FAAAR from finished, so I aplogise for the mess.

The attachement must be renamed to .zip

Guys,

Thanks for your help. It seems adding a call to exit(), after sending out the header and the content, is enough.
