Question

hopefully someone can help me.

I'm new to regexp...

I'm creating a commerce website for a local florists. They offer free postage within the local area (postcodes CM11 and CM12), and i'm looking to create fixed prices for further distances up to a 15 mile radius (they don't deliver outside 15 miles).

Shipping quote 1

• I've created a 'free postage' shipping quote with the regexp condition that the postcode should be CM11 or CM12:
• cm1[1]|cm1[2]
• That works as expected and shows the free shipping if the postcode starts with CM11 or CM12.

Shipping quote 2

• I've created a 'local delivery' shipping quote with the conditions below (this shows all the postcodes within a 15 mile radius)
• cm[1-5]|cm1[3-7]|cm99|ig[2-3]|ig[6-7]|me3|rm[1-9]|rm1[0-9]|rm20|ss0|ss1[1-7]|ss2|ss22|ss[4-9]|ss9[9]

The issue / question I have is how to hide the 'local delivery' option from appearing when the user enters a CM11 or CM12 postcode. They should only see free delivery or collect in store (not the third option of local delivery)

You can see on my site (if you add something the cart and follow the checkout process, experiment with the postcode and see the delivery options change) - http://techyhelp.uk/florist/catalog/5

Answer 1

在您的“本地投放”正则表达式中使用负前瞻来过滤出“ cm12”和“ cm11”：

^(?!cm1[12]$)(cm[1-5]|cm1[3-7]|cm99|ig[2-3]|ig[6-7]|me3|rm[1-9]|rm1[0-9]|rm20|ss0|ss1[1-7]|ss2|ss22|ss[4-9]|ss99)$

Answer 2

sweaver2112 - that worked perfectly thank you.

So the answer to my question has been answered:

use a negative lookahead in your "local delivery" regex to filter out "cm12" and "cm11":

^(?!cm1[12]$)(cm[1-5]|cm1[3-7]|cm99|ig[2-3]|ig[6-7]|me3|rm[1-9]|rm1[0-9]|rm20|ss0|ss1[1-7]|ss2|ss22|ss[4-9]|ss99)$
