javascript - Regex for Number format Validation -


help regex match number pattern .. need accept input in below formats.for implementing validation logic need regex. tried using following 

/(^(([0-9]{5,6}[,])+[0-9]{5,6})$)|(^(([0-9]{1,5}\*[,])+[0-9]{1,5}\*)$)|(^(([0-9]{5,6}[,])+[0-9]{1,5}\*)$)|(^(([0-9]{1,5}\*[,])+[0-9]{1,5})$)/

but not matching scenarios.

following possible inputs

  1. 1123*,2133*,123*,1*
  2. 213433,123453,123*
  3. 123333,123623,678123,12323,
  4. 1123*,123445,166788,123333,..........

conditions - number can have length 5 or 6. inputs must separated comma. if input has * (wildcard search) max length cannot greater 5. ex 123123(not allowed)*

i'm not sure understand requirements of regexp matching pattern, here's preliminary approach.

  • as understand you, numbers [to matched] can have length 5 or 6 , matching pattern should able capture amount of numbers fit description. part, assume there no asterisk characters (*) contained in number sequence.

let's assume have variable input assigned value string 213433,123453,123*. then...

input.match(/\d{5,6}(?!\*)/g);

should capture parts of input variable described. noticed using character sets in attempt (i.e., [0-9] part); \d term accomplishes same thing.the (?!\*) portion used check 5- or 6-digit sequence not followed asterisk character. note: have escape asterisk.

  • in event input possess asterisk character, matched portion can no longer 5 characters. (i hope i'm understanding prompt correctly)! this, following regexp pattern worked (admittedly inexhaustive) 2 tests ran. note: pattern retains (i.e., matches/captures) asterisk character number sequence.

we can assume input variable here assigned string 1123*,2133*,123*,1* purposes of testing out next regexp match pattern.

input.match(/(\d+\*){1,5}/g);

if i'm not mistaken, 2 match patterns can conditionally combined using simple or (|) operator.

input.match(/\d{5,6}(?!\*)|(\d+\*){1,5}/g);

hopefully, helps bit. final test, let's assign input variable string 1123*,2133*,123*,1*,123333,123623,678123,12323 (i concatenated example inputs 1. , 3. provided this). then, running statement directly above returns array:

["1123*", "2133*", "123*", "1*", "123333", "123623", "678123", "12323"]

if wanted retrieve matches without wildcard characters (*), modify expression follows:

a.match(/\d{5,6}(?!\*)|(\d+\*){1,5}/g).map(val => val.replace('*', ''));

to get...

["1123, "2133", "123", "1", "123333", "123623", "678123", "12323"]

php - trouble displaying mysqli database results in correct order -

i have table in database stores events , date expire. want display events on website display current events first expired events after? i have tried following sql $sql = "select noticeid, notice, noticedesc, noticeimg, noticedate, expirydate tbl_notices group noticeid ,expired order expirydate asc"; but returns expired results first due expirydate being ordered asc in query. my tbl_notice structure looks this noticeid => int(4) notice => varchar(100) noticedesc => text noticedate => timestamp noticeimg => varchar(40) expirydate => datetime expired => int(1) 0 current or 1 expired my php code is $sql = "select noticeid, notice, noticedesc, noticeimg, noticedate, expirydate tbl_notices group noticeid ,expired order expirydate asc"; $result = mysqli_query($conn,$sql); if ($result->num_rows > 0) { // output data of each row while($row = $result->fetch_assoc()) { ...
