modding the church sign generator

July 10, 2005 8:36 AM

I'm trying to modify the great Church Sign Generator for my own purposes. I have a php question...

If I wanted the resulting merged image to be written to a file on the server, say, sign.jpg, instead of being displayed in a new window, how would I modify the php to do that?

I don't need every submitted sign to be written to a unique filename. I just need the same file overwritten every time a sign is submitted.

I assume this is the part of the source code that would be replaced by something different:

+++++++++++++++++++++++++++++++++++++++++++++

/* Now that the image is built, it gets sent to the browser. First, send out HTTP headers to
tell the browser a JPEG image is coming. */
header("Content-Type: image/jpeg");
header("Content-Disposition: inline; filename=churchsign.jpg");

/* The imagejpeg() function sends the output img to the browser. */
imagejpeg($output_img);
++++++++++++++++++++++++++++++++++++++++++++++

I should note that I don't know any php, except to be able to change the variables, paths, etc. to work in my environment.

Remove the two header lines and add the filename to the imagejpeg function:

imagejpeg($output_img,$filename);

That'll write it to a file instead of to the browser.

Depending on what you are trying to do, you might be interested in this page. It's in Finnish but you'll be able to figure it out. Basically, pick a picture, and write what you want next to where it says "iskulause".

I stripped out the header info and used the line
imagejpeg($output_img,$newfile.jpg);

...which creates a jpg file called "jpg"!!

And it is the right image, which is exciting. If I go in and manually rename it on the server and then display it, it's fine. But I can't make it name itself "newfile.jpg".

Then I added the line

rename("jpg", "newfile.jpg");

which made everything work. Thanks all!

Did you try imagejpeg($output_img,"newfile.jpg"); ?

I did try that, it threw an error, or didn't work, or something. I don't remember. But now it does work...and i just have to do the tedious work of plugging in the pixel coordinates of all the characters.

Thanks so much for your help. I'll shoot you a link when it's all done.

Please send me the link when you get done, I'd be interested in seeing what you do with it. I apologize for being rather grumpy about doing tech support, but I was getting way too many e-mails from people that were asking wide open questions, like "How do I make this work on my website?" (to which the answer is, "Learn PHP") rather than specific questions like this.
