VoucherPress

Description

Thanks for using VoucherPress. It’s great to see so many people creating vouchers for all kinds of business. From pizza joints to jewellers, cleaning companies to sports clubs – you’ve created thousands of vouchers, and I’m really proud to have created something which has been useful to so many people.

As I work on the next version of VoucherPress it would be really helpful if you could fill in this short survey. Many thanks for your time.

Have you ever wanted to give away vouchers, tickets, coupons or tokens on your website? If so this plugin is for you. You can create a voucher with whatever text you want, choosing the layout and font from a range of templates (you can also add your own templates). Vouchers can then be viewed, downloaded and printed from a specified URL.

There are shortcodes to add a link to a particular voucher, to show an unordered list of all your vouchers, or to show the registration for to request a restricted voucher.

You can require visitors to provide their name and email address to get a voucher. If an email address is required an email is sent to the address with a link to the voucher URL. Each voucher has a unique code, and vouchers that have an email address associated with them can only be used once, so once a registration-required voucher is downloaded it can’t be downloaded again.

Hooks

From version 1.1.2 the plugin also offers a selection of hooks which you can use to run your own custom code. The hooks are:

voucherpress_create

When a voucher is created, this hook returns the properties of the voucher. You can use it like this:

add_action( ‘voucherpress_create’, ‘my_voucherpress_create_function’ );
function my_voucherpress_create_function( $id, $name, $text, $description, $template, $require_email, $limit, $startdate, $expiry ) {
// do something here…
}

voucherpress_edit

When a voucher is edited, this hook returns the properties of the voucher. You can use it like this:

add_action( ‘voucherpress_edit’, ‘my_voucherpress_edit_function’ );
function my_voucherpress_edit_function( $id, $name, $text, $description, $template, $require_email, $limit, $startdate, $expiry ) {
// do something here…
}

voucherpress_register

When someone registers to download a voucher and an email is sent to them, this hook returns the voucher and the users details. You can use it like this:

add_action( ‘voucherpress_register’, ‘my_voucherpress_register_function’ );
function my_voucherpress_register_function( $voucher_id, $voucher_name, $user_email, $user_name ) {
// do something here…
}

voucherpress_download

When someone downloads a voucher, this hook returns the voucher and the users details. You can use it like this:

add_action( ‘voucherpress_download’, ‘my_voucherpress_download_function’ );
function my_voucherpress_download_function( $voucher_id, $voucher_name, $code ) {
// do something here…
}

The plugin also makes use of the __() function to allow for easy translation.

Thanks to Christian Serron (https://twitter.com/cserron) for the code to make the vouchers work in widgets (currently disabled, I’m working on this) and to Barry (https://www.betakeygiveaway.com/) for bug testing above and beyond the call of duty.

Shortcodes

There are four shortcodes available. The first shows a link to a particular voucher, and is in the format:

[voucher id=”123″]

The “id” parameter is the unique ID of the voucher. The correct ID to use is available in the screen where you edit the voucher.

You can also how the description after the link:

[voucher id=”123″ description=”true”]

The second shows a link to a voucher, but with a preview of the voucher (just the background image, no text) and the voucher name as the image alternate text:

[voucher id=”123″ preview=”true”]

And you can show the description after the preview as well:

[voucher id=”123″ preview=”true” description=”true”]

You can also show an unordered list of all your live vouchers using this shortcode:

[voucherlist]

And a list of all live vouchers with their descriptions:

[voucherlist description=”true”]

And you can also show the form for people to enter their name and email address if they wish to register for a restricted voucher:

[voucherform id=”123″]

The shortcodes for any voucher can be found on the edit screen for that voucher. Just click the ‘Shortcodes’ button.

Installation

The plugin should be placed in your /wp-content/plugins/ directory and activated in the plugin administration screen. The plugin is quite large as it includes the TCPDF class for creating the PDF file.

FAQ

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.

Have installed and created a voucher. Where the heck is the shortcode? I wish you Gurus would put some instructions up

Excellent Plugin

As a WordPress programmer, I use this plugin in a variety of ways. Needs some more internal reports, but easily created my own thru phpmyadmin. Data is reliable and easy to use.
