Showing Data in an image

darylr

Hi all,

Just wondering how I could go about creating an image which displays dynamic data.. for example, have one main image file that people can use as sigs in forums, that will display their information.

Not sure if thats explained clearly, but how can I link the image to the database to show details of the person in question? (So, if they put ...image.png?id=34 in their signature, it will collect all their info from the database using the ID, and then display it on the image?)

Anyone able to help? 🙂

Thanks,

Daryl

There are plenty of [man]image[/man] functions you could use to build images dynamically.

Hi again,

I've created a file but now forums wont let me connect to it in signatures

With PHPBB, it displays text inside the [img] tags, and on Snitz it displays the image, but it doesnt show the details because the $id tag is being blocked (instead of = in the sign, it changes to %20 )

How can I make this work in forums? I've seen the same type done successfully on the same forums!

There are a few ways you can do it.

Some are having a page that takes the contents of the query string and then writes that over the image, so you can just change the URL anmd the image is generated on the fly. Some places will not allow that, as they check for query strings in img tags.

What I do for my News Sigs is to create a background image then use a class I wrote along with imagettftext() to write the content and save the modified file. I then use the crontab in linux tio update the images periodically with content.

My class is still at version 1, but its been pretty stable in the 10 months i've used it.

Im unsure how to go about it.. my code is as follows;

header("Content-type: image/png");
$im    = imagecreatefrompng("images/sig.png");
$black = imagecolorallocate($im, 0, 0, 0);

imagestring($im, 4, 450, 5, $reaid, $black);
imagestring($im, 3, 10,40, $details, $black);
imagestring($im, 3, 10, 50, $totalhours, $black);
imagestring($im, 3, 10, 60, $lastflight2, $black);
imagestring($im, 3, 10, 70, $hub2, $black);
imagestring($im, 3, 10, 80, $equip, $black);
imagepng($im);
imagedestroy($im);

Any pointers?
