It’s not pretty, but sometimes you need to check an address input to see if it’s a PO box.\u00a0 Rules will be different around PO boxes.<\/p>\n
For that, I use a simple javascript pattern.\u00a0 It has the down side of checking for “P”, “O”, and “Box” in the string in order, so something like Poratable Box Road will fail validation, but I don’t think that’s a real road, so it seems to work for real world use cases.<\/p>\n
var street1 = jQuery('#address1').val();\r\nvar street2 = jQuery('#address2').val();\r\n\r\nvar pattern = new RegExp('\\\\b[p]*(ost)*\\\\.*\\\\s*[o|0]*(ffice)*\\\\.*\\\\s*b[o|0]x\\\\b', 'i');\r\n\r\nif(street1.match(pattern) || street2.match(pattern) {\r\n alert('We do not ship to PO boxes. Please enter a different address\");\r\n return false;\r\n}<\/pre>\n <\/p>\n","protected":false},"excerpt":{"rendered":"
