Een reguliere expressie moet beginnen en eindigen met een slash ("/"). Een bibliotheek met reguliere expressies kun je vinden op http://www.regexlib.net/. Kijk wel of in deze "patterns" de slashes al toegevoegd zijn.

Om je reguliere expressie te testen kun je dit gebruiken: regex tester.

Voeg goed werkende reguliere expressies hier toe!

Voorbeelden (elke voorbeeld is één regel):

BELANGRIJK: Reguliere expressie in conditie

Als je de reguliere expressies in de conditie editor gebruikt, voeg dan NIET de beide slashes toe.

E-mail validatie

/(\w[-._\w]*\w@\w[-._\w]*\w\.\w{2,3})/

De bovenstaande regex zal geen e-mailadres met "+" valideren, wat wel is toegestaan en wordt aanbevolen door Gmail. Een versie die de "+" wel toestaat:

/^(\w[-._+\w]*\w@\w[-._\w]*\w\.\w{2,3})$/

Dit is volgens mij beter dan het origineel (ook omdat er "start van string" en "eind van string" tekens zijn toegevoegd), maar het is niet perfect. Het staat ook abc+++defg@somemail.office.com toe, de regex zou eigenlijk zo moeten zijn dat er maar een "+" teken is toegestaan.

Postcodes

Australische Postcodes

/^[0-9]{4}/

Braziliaanse Postcodes

/^[0-9]{2}\.[0-9]{3}-[0-9]{3}$/

Canadese Postcodes

/^[a-zA-Z]\d{1}[a-zA-Z](\-| |)\d{1}[a-zA-Z]\d{1}$/

VS Postal Codes

/^[0-9]{5}([- /]?[0-9]{4})?$/

Verenigd Koninkrijk Postcodes

/^[A-Z][A-Z]?[0-9][A-Z0-9]? ?[0-9][ABDEFGHJLNPQRSTUWXYZ]{2}$/i

Note that this is not very exact, and a more exact validation is much more complex. For example, see StackOverflow answer and Wikipedia for more information.

Telefoonnummers

VS Telefoonnummer:

/^(?:\([2-9]\d{2}\)\ ?|[2-9]\d{2}(?:\-?|\ ?))[2-9]\d{2}[- ]?\d{4}$/

of

/^[\(\)\.\- ]{0,}[0-9]{3}[\(\)\.\- ]{0,}[0-9]{3}[\(\)\.\- ]{0,}[0-9]{4}[\(\)\.\- ]{0,}$/

This second option will match all phone Canadian and US phone numbers that include non-digit symbols including

 . ( ) - (space)

This will allow you to match phone numbers which resemble below.

(555)555 5555
555.555.5555
555 555 5555
(555)-555-5555
555-555-5555
555555555

Australisch telefoonnummer

The following patterns match all various Australian mobile and landline phone numbers including with "+61" country prefix eg:

(02) 9123 6535
03 1234-5345
0412 345 678
+61 2 3456 789

But not:

234 3450 234
a234 534 3432
134567
123456789013

Brackets, white space and hypens are ignored.

NOTE: The 'PRECICE' versions listed here match against the first four or five didgets in a number to ensure that they are valid Australian numbers.

The 'NOT VERY PRECISE' only match against the first and second didgit so may allow invaid numbers

^(1[8-9]|[2-5][0-9]|6[0-5])$

Number validation

Numbers from 1 to 99999

/^([1-9]|[1-9][0-9]|[1-9][0-9][0-9]|[1-9][0-9][0-9][0-9]|[1-9][0-9][0-9][0-9][0-9])$/
/^[1-9][0-9]{0,4}$/ does the same as above but should run a little faster

Numbers from 1 to 999, 1.000 to 999.999 to 999.999.999

/^[1-9][0-9]{0,2}(?:\.[0-9]{3}){0,2}$/
accepts numbers from 1 to 999, 1.000 to 999.999 to 999.999.999 but
rejects numbers like 999.1.1 , 94.22.22, 999.1.22, 999.11.1, 999.1.333

Number validation with optionnal decimal (for price)

/^([1][0-9][0-9]|[1-9][0-9]|[0-9])((\.)[0-9][0-9])?$/ accepts numbers from 0 to 199, with 2 decimal optionnal

/^[1-9][0-9]{0,2}(?:,?[0-9]{3}){0,3}\.[0-9]{2}$/
forces two decimal points
accepts numbers from 1.00 to 999,999,999.00 with an optional comma delimiting thousands/millions
including all of the following: 1.00, 1,000.00 , 12,345.67 , 12345,02 , 123,456,468.00 , 1234566.00 , 123456789.00
but not 1,23.00 , 12,3.4 or 1234,43.04

/^[1-9][0-9]{0,2}(?:,?[0-9]{3}){0,3}(?:\.[0-9]{2})?$/ same as above but the two decimal points are optional

Maand (1-12)

If you want to ask for the month a person was born you can validate the input as follows:

/^[0]*[1-9]$|^[0]*1[0-2]$/

Minimum width (set to 3 in this example)

/^.{3,}$/

Valuta

US currency (dollar sign and cents optional)

/^\$?\d+(\.(\d{2}]]?$/

Tekst validatie

currently multiple short text doesn't support minimum or maximum answers. One way around this is to use a long free text type question with a regular expression.

The following test for at least one word per line for at least 3 lines and no more than 10 lines.

/(?:[^,.;:?!& \n\r]+(?: [^,.;:?!& \n\r]+)*)(?:[,.;:?!& \n\r]?(?:\n|\r|\n\r|\r\n)(?:[^,.;:?!& \n\r]+(?: [^,.;:?!& \n\r]+)*)){2,10}/is

If you wanted, say five words per line you could change the first and last star/asterisk to {4,} e.g.

/(?:[^,.;:?!& \n\r]+(?: [^,.;:?!& \n\r]+){4,})(?:[,.;:?!& \n\r]?(?:\n|\r|\n\r|\r\n)(?:[^,.;:?!& \n\r]+(?: [^,.;:?!& \n\r]+){4,})){2,10}/is

If you wanted one or more words per line on between 1 and 5 lines, you can change the content of the last curley braces to {0,4} (note you use 0 because you're already matching the first line.

/(?:[^,.;:?!& \n\r]+(?: [^,.;:?!& \n\r]+)*)(?:[,.;:?!& \n\r]?(?:\n|\r|\n\r|\r\n)(?:[^,.;:?!& \n\r]+(?: [^,.;:?!& \n\r]+)*)){0,4}/is

Woordentellen

The following restricts the number of words allowed to a minimum of 1 and a maximum of 200

/^[-\w]+(?:\W+[-\w]+){0,199}\W*$/

To increase the minimum change the zero part of {0,199}

To increase or decrease the maximum change the "199" part of {0,199}

Tijd validatie

There are a number of ways of writing time formats. Some of the possible options are 12 hour or 24 hour, with seconds or without. Currently (2009/04/06) LimeSurvey (v1.80plus) doesn't have a Time queston type so instead you can use "short free text" with one of the nine validation regular expressions below:

The following three validation strings test for 24 hour time (in order of appearences) without seconds, with optional seconds lastly with seconds required.

/^(?:[01][0-9]|2[0-3]):[0-5][0-9]$/

/^(?:[01][0-9]|2[0-3]):[0-5][0-9](?::[0-5][0-9])?$/

US States

To validate for one state use the following (example is Texas):

TX uppercase only = /^(TX)$/
tx lowercase only = /^(tx)$/
TX upper or lowercase = /^([T|t][X|x])$/

Schuttingtaal filter

Om schuttingtaal in antwoorden te verwijderen:

/^(?i)((?!\bSCHUTTINGTAAL\b).)*$(?-i)/

Vervang "SCHUTTINGTAAL" met het woord dat u uit de antwoorden wilt filteren.

De \b zorgt ervoor dat woorden als "borstel" en "konterfeitsel" geaccepteerd worden als je "borst" en "kont" als schuttingtaal ziet. Dit werkt ook als je andere woorden, namen, enz. uit antwoorden wilt verwijderen.
