Incrementing / Decrementing Operators
++
increment operator
--
decrement operator
Example Name Effect
---------------------------------------------------------------------
++$a Pre-increment Increments $a by one, then returns $a.
$a++ Post-increment Returns $a, then increments $a by one.
--$a Pre-decrement Decrements $a by one, then returns $a.
$a-- Post-decrement Returns $a, then decrements $a by one.
These can go before or after the variable.
If put before the variable, the increment/decrement operation is done to the variable first then the result is returned. If put after the variable, the variable is first returned, then the increment/decrement operation is done.
For example:
$apples = 10;
for ($i = 0; $i < 10; ++$i) {
echo 'I have ' . $apples-- . " apples. I just ate one.\n";
}
Live example
In the case above ++$i
is used, since it is faster. $i++
would have the same results.
Pre-increment is a little bit faster because it really increments the variable and after that 'returns' the result. Post-increment creates a special variable, copies there the value of the first variable and only after the first variable is used, replaces its value with second's.
However, you must use $apples--
, since first, you want to display the current number of apples, and then you want to subtract one from it.
You can also increment letters in PHP:
$i = "a";
while ($i < "c") {
echo $i++;
}
Once z
is reached aa
is next, and so on.
Note that character variables can be incremented but not decremented and even so only plain ASCII characters (a-z and A-Z) are supported.

Another way to totally override the cart.php is to copy:
woocommerce/templates/cart/cart.php to
yourtheme/woocommerce/cart/cart.php
Then do whatever you need at the yourtheme/woocommerce/cart/cart.php

The minicart buttons are hooked in
woocommerce_widget_shopping_cart_buttons
action hook (in the cart/mini-cart.php WooCommerce template). You will find the details HERE on includes/wc-template-hooks.php core file. It calls 2 functions that are displaying the buttons.In the code below I remove first the original buttons and I replace them by the same ones where the links are customized. For each you can change the link to feet your needs (I have added in the links
?id=1
(at the end) just for testing purpose, to check changes):Code goes in function.php file of your active child theme (or theme) or also in any plugin file.
All code is tested on Woocommerce 3+ and works.
