VoucherPress is a WordPress plugin that allows you to give downloadable, printable vouchers/tickets/coupons/tokens in PDF format away on your site.
My voucher PDF files are corrupted. Why?
This is normally because PHP isn’t given enough memory to create print-resolution PDF files. If you open one of your corrupted PDF files in a text editor it will say something like this:
Fatal error: Out of memory (allocated 31981568) (tried to allocate 456135 bytes) in
/some/thing/here/wp-content/plugins/voucherpress/tcpdf/tcpdf.php
Speak to your hosts or system administrator to give PHP more memory. I’m also working on a way for VoucherPress itself to work around this problem.
Why is the plugin so big? It’s over 20 MB!
I know, and I’m sorry, but the TCPDF sytem which generates the PDF documents is pretty big. And there’s 40+ default layout templates which aren’t small either.
Why did you write this plugin?
I’m not sure. It seemed like a good idea, and gave me opportunity to learn a little bit about the TCPDF class.
Does this plugin work with any e-commerce plugins?
Not at the moment, but I’m sure it could if those e-commerce plugin developers want to get in touch.
Can I add my own codes, for example if I want to give away numbered coupons?
Yes, you can add your own codes for any voucher. When people download the voucher they will be given one of your codes (in the same order you entered them). Once one of your codes is used on a voucher it can’t be used again.
