unable to get value from global variable in php - php

Question

This is the code I have in one of my php plugin file.
add_filter('woocommerce_cart_totals_order_total_html','test_func');
function test_func() {
global $woocommerce, $totalship;
$cart_subtotal = (float)$woocommerce->cart->subtotal;
if( $cart_subtotal < 1000 ) {
$cart_subtotal01 = $woocommerce->cart->get_cart_subtotal();
$cart_subtotal11 = explode('</span>', $cart_subtotal01);
$text_tax ='';
if($cart_subtotal11[1]) {
$text_tax = $cart_subtotal11[1];
}
$allcarttotal = $cart_subtotal+$totalship;
$value = '<strong><span class="amount">Rs. ' . $allcarttotal . '</span>'.$text_tax.'</strong>';
$citrus_total_val = $value;
return $citrus_total_val;
//return $value;
}
else {
$docart_total = $cart_subtotal - $totalship;
$citrus_total_val = $docart_total;
return $citrus_total_val;
//return $docart_total;
}
}
global $citrus_total_val;
I am trying to pass the value of $citrus_total_val to another plugin for payment gateway.
This is the code:
global $citrus_total_val;
//Setup URL and signatue etc.
$currencycode = get_woocommerce_currency();
$merchantTxnId = $order_id;
$orderAmount = $citrus_total_val;
But the value is not passed here. What am I doing wrong?

Answer 1

Try this:
$citrus_total_val = '';
add_filter('woocommerce_cart_totals_order_total_html','test_func');
function test_func() {
global $woocommerce, $totalship;
global $citrus_total_val;
$cart_subtotal = (float)$woocommerce->cart->subtotal;
if( $cart_subtotal < 1000 ) {
$cart_subtotal01 = $woocommerce->cart->get_cart_subtotal();
$cart_subtotal11 = explode('</span>', $cart_subtotal01);
$text_tax ='';
if($cart_subtotal11[1]) {
$text_tax = $cart_subtotal11[1];
}
$allcarttotal = $cart_subtotal+$totalship;
$value = '<strong><span class="amount">Rs. ' . $allcarttotal . '</span>'.$text_tax.'</strong>';
$citrus_total_val = $value;
return $citrus_total_val;
//return $value;
}
else {
$docart_total = $cart_subtotal - $totalship;
$citrus_total_val = $docart_total;
return $citrus_total_val;
//return $docart_total;
}
}

try putting it in the function, like you did with global $woocommerce, $totalship;
add_filter('woocommerce_cart_totals_order_total_html','test_func');
function test_func() {
global $woocommerce, $totalship;
global $citrus_total_val;
$cart_subtotal = (float)$woocommerce->cart->subtotal;
if( $cart_subtotal < 1000 ) {
$cart_subtotal01 = $woocommerce->cart->get_cart_subtotal();
$cart_subtotal11 = explode('</span>', $cart_subtotal01);
$text_tax ='';
if($cart_subtotal11[1]) {
$text_tax = $cart_subtotal11[1];
}
$allcarttotal = $cart_subtotal+$totalship;
$value = '<strong><span class="amount">Rs. ' . $allcarttotal . '</span>'.$text_tax.'</strong>';
$citrus_total_val = $value;
return $citrus_total_val;
//return $value;
}
else {
$docart_total = $cart_subtotal - $totalship;
$citrus_total_val = $docart_total;
return $citrus_total_val;
//return $docart_total;
}
}
