How do I make it so that the bars still draw correctly, but they don't draw from the code, they draw from $barcode. or how do I put the value of $barcode into there.........currently it has to be a 8 digit $barcode and I believe 4-5 random numbers either on front or back.  I want to be able to make $barcode have the value of an ean 13 barcode(which is how many numbers? 13 right?)  and so that that is the only thing dictating barcode(I do know how to make it more numbers, but I cant do that because of the 5 random ones).  does this make sense?

Hi guys, to compliment my ORM.

On the multiple choice sheets which are scanned into images and then interpreted with the OMR thier is a barcode (like the ones on stuff you buy from the shops), this barcode contains digits to decide the layout of the sheet and how to run the OMR. How can I get PHP to read and understand the barcode. The barcode is originally generated by PHP and now I need PHP to read it and convert to numbers which then I run against mySQL db to enable the OMR to read correctly.

If anyone can suggest a script or method or even a different way to tackle the issue it would be greatly appreciated. Thanks in advance.

Hi, I'm trying to run an api from upcdatabase.com. I works fine but some barcodes are 8digits or 13digits, i need those barcodes to be changed by adding in zero's if 8 or subtracting 1 zero if 13.

It needs to do this before being sent to the sever. Your help is really appreciated this should be simple but has got be stumped i don't know where to even put the code... here's what i've got so far. THANKYOOUUU FOR YOUR TIME!

Hello,
I'm interested in hiring someone if it's too difficult but possible, or doing it myself if isn't too much work (I know basic php) which I doubt.
I want that when I scan an item with my barcode pistol it automatically changes something in my page. I mean, I have a delivery system, so when the package arrive I want just to scan the barcode of the package and that automatically changes the status in the client area on my php site to "Ready".

What are the requirements, and if I need to hire someone what would be the estimated reasonable price to pay.

Thanks a lot.

Best Regards
