regex for 1-3 figures, but not 0

Hi guys,

I am looking for a regex for 1-3 figures, such as 145 or 44 or 54, but the value cannot be 0.

Anyone an idea?

Hi Dat,

thanks for responding. I will try it, but it looks it bit odd to me. The regex I am using in the Links SQL database property field is a bit different, it looks like ^[0-9]{1,8}$

But that doens't mean anything. I am just a user, not an expert.

Its a little difficult, as I'm guessing you need to use 0 in the string? i.e;

405 would be ok
045 would NOT be ok
123 would be ok
450 would be ok

Am I correct?

Hi Andy,

good to hear from you. No, actually, ONLY 0 is not allowed.

In that case, how about this;

^123456789+$

?

Regex isn't my strongest point (normally get there by trial and error).

Tried that, but then I do not have 40 in there which should be allowed.

Not sure what you mean Unsure

Can you give me say 5 examples of what would be alowed, and 5 that would not be allowed?

Re: [vacationrentals] regex for 1-3 figures, but not 0 In reply to

In that case, this should work;

^[123456789]{,1}[0-9]{1,5}$

Does that do the job?

Sorry, it doesn't. It cannot contain the value 40 this way.

Thanks for that, but it didn't work. For example it did not let enter 40 as a number.

Re: [vacationrentals] regex for 1-3 figures, but not 0 In reply to

Hi Stuart

please try the following regex:

Code:

 ^(?:(?!0)\d\d\d)$

Hope it helps...

Well, I've tested it and it works on my system. Please let me know how/where you've implemented the code exactly and what kind of errors/problems you're experiencing now.

Thanks

Hi oliver,

I appreciate you are taking the time. When I am trying to enter 40, the system tells me that I can't, which is a result based on the regex.

Re: [vacationrentals] regex for 1-3 figures, but not 0 In reply to

Hi Stuart,

oooops, you're right. I've tested it with three numbers like 400, 411, 004 etc. The sample I've posted requires three numbers and doesn't allow you to enter two or one of them.

Just modify the regex like this:

Code:

  ^(?:(?!0)\d{1,3})$

I hope this one works for you - good luck!

Cheers,
Blush

Cool Dan, your link is very helpful. It's faster and more comfy to test regular expressions via webform than writing a special test script!

Thanks for your input

Hi BlueBottle

we've got it working with our regex (as already mentioned). I've just checked your regex and it doesn't seem to do what vacationrentals wanted - have you been able to test it?

Just for the sake of perl golf

^[1-9]\d?\d?$

-gordon

s/(\d{2})/chr($1)/ge + print if $_ = '8284703280698276687967';
