Is there a way to set an input mask or validation rule in MS Access 2016 so that certain elements are optional?
Employee Reference can be in a number of formats: starts with a character E follow by space and 10 numbers. These will be mandatory and then the last character should be optional.
So, is there a way for me to set the input mask so that the first letter, space and 10 numbers are mandatory and last character is optional?
For example:
E <space> 100234240 <optional Letter>
E 100234240A
or
E 100234240
As described in the official documentation, you will require the following input mask characters to achieve your desired result:
0 User must enter a digit (0 to 9).
a User can enter a letter or a digit.
"" Characters enclosed in double quotation marks will be displayed literally.
You may also wish to use:
> Converts all characters that follow to uppercase.
Given the above, I might suggest the following input mask:
>"E "0000000000a;0
Here, the 0 following the semi-colon in the input mask indicates that the mask characters will be stored along with the data (i.e. the "E " will also be stored).
And if you want a different placeholder character, perhaps something like:
>"E "0000000000a;0;#

I would like to allow my input box in HTML to receive only integers from -99 to 99,
but if I use pattern="[-][0-9][0-9]{2,3}" or [-0-9]|[0-9]{2,3} or anything similar it allows the user to place from -99 too 999.
How can I make this negative sign - only optionally at the front of the introduced digit?
I.e. either the user will use it at the beginning of the introduced value, and if not, max 2 digits in a whole (above 0) value.
First, you could use type="number" with min and max attributes, which would probably be the best option.
Alternatively, the right pattern is -?[0-9]{1,2}.
- is a literal minus sign (no need to enclose it in brackets)
? means the previous atom (in this case the minus sign) is optional
[0-9]{1,2} means one or two digits, so anything from 0 to 99 (including 00, 01…)
As a user is typing their new password, I want them to be able to see if their password meets the requirements or not. I have a Regex pattern set up inside the input tag, and if the requirements aren't met, the input box is outlined in red and the form can't be submitted. This looks like:
<input type="password" pattern="((?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.[!###$%&?]).{8,32})" placeholder="Password" required />
I adapted that pattern from here. I have it so that the user's password must contain 8-32 characters, one uppercase letter, one lowercase letter, one special character (!##$%&?), and one number, and that works fine. However, I also want to exclude some special characters from the input, for example, the semicolon (;). I have tried adding (?!.[;]) like so:
((?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.[!###$%&?])(?!.[;]).{8,32})
This breaks the entire pattern, though. Could someone explain what I am doing wrong and how I can fix it? Or would it be better to do this manually by using a Javascript listener to check if the password meets the requirements each time the user does a keypress?
Try with:
((?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[!###$%&?])(?!.*[;]).{8,32})
Fine-tunings from your regex:
Added back an asterisk * to the positive lookahead for symbols list [!###$%&?]
Added back an asterisk * to the negative lookahead for symbol [;]
You need an asterisk * after the dot . in order to allow matching of multiple characters (by *) for any character (by .). Otherwise, your regex allows only ONE single character before the symbols to include and exclude.
Recently I tried alot but I still unable to figure how should I able to validation for my text field. I hope I can get some help from here, my questions is I want to validate input text field only accept A-Z a-z 0-9 and space within word. And at least one char or number.
For example, "abc def" , "abc092", "abcdef"
Only in HTML input tag element .
I tried this
but this pattern unable to fullfil my requirements.
the pattern i want to achieve is
1) abc def
2) abcdef
3) abc123
4) a1b2c3 d4e5
5) allow to have empty space within words
the pattern i dont want to accept is
1) empty string
2) no alot of whitespace at the begining or end of the string
3) no bracket and etc special characters
Try
<input type="text" pattern="^\w+([\w ]*\w)*$">
Basically the break down is this:
\w+ - Select a word character ("A-z0-9") one or more times
()* - Select what's in here 0 or more times, which is
[\w ]*\w - Select a word character or space one or more times followed by another word character
No leading or trailing white space allowed. Only word characters allowed and internal spaces.
For some unit tests and breakdown of the regex see: https://regex101.com/r/7UnL9J/1
You can use the Pattern attribute with regex but it is supported only in HTML 5.
Like this " id="username" pattern="[A-Za-z0-9]+"

Have you tried this?
<input type="text" pattern="[a-zA-Z0-9\s]+">
i'm not good in html pattern validation.
I have this problem, my input text is valid only : min 3 max 30 chars,
white space at first and at end of the string is not allowed, is allowed white space between one word and another is allowed, is allowed A-Za-z, first char of word it must be Uppercase and the others word it must be Lowercase.
Thanks.
--UPDATE--
input#name
Valid Examples:
'Mario Giovanni'
'Maria'
'Jacopo Karol Pio'
'Jacopo K'
Invalid Examples:
' Mario Giovanni'
'Mario Giovanni '
' Mario Giovanni '
'Mario Giovanni'
'maria'
'mAria'
'Antonio mario'
If you need pure regex then this should work for you:
<input type="text" pattern="(?=^.{3,30}$)^[A-Z][a-z]*(?: [a-z]+)*$">
(?=^.{3,30}$) - use a positive lookahead to make sure we have between 3 and 30 chars
^[A-Z] - require start with a capital letter
[a-z]* - optionally allow lowercase letters to follow
(?: [a-z]+)* - optionally allow a repeating group of a space char follow by one or more letters
$ - end of string anchor
You will want to use a Regular Expression pattern to check whether the input is valid or not, as well as the maxlength and minlength attributes to ensure that the input is between 3 and 30 characters.
Regarding the RegEx pattern, we must:
Start at the beginning of the input: ^
Verify that the first character is between A and Z: [A-Z]
Verify that the following characters before the last one are lowercase letters or spaces: [a-z ]*, where * indicates that there might be multiple characters matching that part of the pattern; if you only want to allow one space between word, then use ([a-z]* ?)
Verify that the last character is a lowercase letter: [a-z]$, where $ indicates the end of the input
Below is the code I would use.
<input type="text" minlength=3 maxlength=30 pattern="^[A-Z][a-z ]*[a-z]$">
Looks like what you wait is:
<input type="text" pattern="(?=^.{3,30}$)^[A-Z][a-z]+( [A-Z][a-z]+)*$">
Notice this is being validated in the user browser, and doesn't configure a secure input validation. You should check the input again at server-side before using it anywhere.
I have a table with an ID number which has a special format as follow: 2500-001
By default the number format does not accept dash(-) in the middle of number and I can not make it a Text field as I need this ID as the Primary Key.
Would you please tell me if there is anyway to achieve this in Design View?
Thank you in advance
Use a text box input mask.
You can specify whether or not the dash is included in the data. See here for more information about input masks:
The three parts of an input mask
Input masks are made up one mandatory
part and two optional parts, and each part is separated by a
semicolon. The purpose of each part is as follows:
The first part is mandatory. It includes the mask characters or string
(series of characters) along with placeholders and literal data such
as, parentheses, periods, and hyphens.
The second part is optional and
refers to the embedded mask characters and how they are stored within
the field. If the second part is set to 0, the characters are stored
with the data, and if it is set to 1, the characters are only
displayed and not stored. Setting the second part to 1 can save
database storage space.
The third part of the input mask is also
optional and indicates a single character or space that is used as a
placeholder. By default, Access uses the underscore (_). If you want
to use another character, enter it in the third part of your mask.
