Poem

A hop and a skip through code we compile,
I tuck IRR in with a satisfied smile.
Symbols aligned, decimals at zero—
Rial joins the ledger, a brand-new hero.
Thump-thump goes my review, concise and spry,
Carrots for currencies—now watch them fly! 🥕💱

160-160: Consider maintaining alphabetical order in the currency list.

The IRR entry is correct, but it's appended at the end rather than in alphabetical position. To maintain consistency with the rest of the currency list (which appears alphabetically sorted by currency code), consider placing IRR between 'INR' (line 77) and 'ISK' (line 78).

Apply this diff to move IRR to its alphabetical position:

 		'INR' => __('Indian Rupee', 'ultimate-multisite'),
+		'IRR' => __('Iranian Rial', 'ultimate-multisite'),
 		'ISK' => __('Icelandic Króna', 'ultimate-multisite'),

And remove the duplicate entry from line 160:

 		'ZMW' => __('Zambian Kwacha', 'ultimate-multisite'),
-		'IRR' => __('Iranian Rial', 'ultimate-multisite'),

433-433: Consider maintaining alphabetical order in the zero-decimal currency list.

IRR is correctly classified as a zero-decimal currency (consistent with how payment processors like Stripe handle Iranian Rial). However, to maintain consistency with the alphabetically sorted list, consider placing IRR between 'GNF' and 'JPY'.

Apply this diff to move IRR to its alphabetical position:

 		'GNF', // Guinean Franc
+		'IRR', // Iranian Rial
 		'JPY', // Japanese Yen

And remove the duplicate entry from line 433:

 		'XPF', // CFP Franc
-		'IRR', // Iranian Rial
 	];

196-198: LGTM! Symbol mapping is correct.

The Rial symbol '﷼' (U+FDFC) is properly mapped for IRR. The implementation follows the existing pattern in the switch statement.

LTGM. Thanks

@mahyarrezghi Just wondering which payment method you will be using because I don't think stripe supports IRR

[mahyarrezghi]

@superdav42 That’s right, nearly all global payment gateways don’t support IRR. I created an MU-plugin to integrate one of the Iranian payment gateways instead.
