validation string

[Dkuzik]

Hello,

 

I have been looking at how to do validation on custom fields.  I can't find much info.

How would i do the 2 below validation strings?

 

(Panel Username)  - (Leave empty if you want system generates randomly), 6 to 28 characters in length, alpha-numeric or underscores only, DO NOT use email address, space, @, /, or other special characters.

(Panel Password) - (Leave empty if you want system generates randomly), 6 to 28 characters in length, alpha-numeric and underscores only.

 

 

thanks

Forgot i believe this is the string

 

/^[a-z\d_]{6,28}$/i
I think this is right.  Not sure about capital letters and if customer leaves blank

Hi Dkuzik,

Are these custom fields on your order form?

[Dkuzik]

yes this string is correct found last night on whmcs website.

Is there a short code for special characters or do i need to list each one

[Dkuzik]

I know this is the validation code for alpha numeric and underscore 6-28 characters      /^[a-z\d_]{6,28}$/i

Is there are special code for special characters like (*&^%$#@!><?"; etc. I don't what to have to type them all

If you want them to be allowed, then they have to be included in the character match.  For some of them, you may need to escape the character via a "\" before it.  Also, https://regex101.com/ helps greatly in testing and figuring out regex .

thanks.  I was hoping for short code on special characters but don't think there is.

This is my validation. /^[a-z\d~!@#$%^&*()-_=+[{]};:’”,<.>?|\/\\]{8,16}$/I

upper case lower case numbers special characters 8-16 characters long

\W might be what you want then if you want all special characters to be valid.  Where \w matches letters, numbers - alphanumeric, \W matches non-letters, non-number - non-alphanumeric.
