Validate telephone number

I am trying to use IsMatch function to validate telephone number text input which only allowed user to enter digit. No special characters such as "-" and any space is allowed. 

 

If user enter the wrong format, the BorderColor of the text input will turn into red.

 

Any help would be much appreciated! Thank you.

Re: Validate telephone number

Hi @shabila97 ,

Do you want to validate telephone number using IsMatch() function within your app?

How many digits does your telephone number have? 10?

 

Based on the needs that you mentioned, I have made a test on my side, please take a try with the following workaround:1.JPG

Set the BorderColor property of the Text Input box to following:

If(
Not(IsMatch(TextInput1.Text, "\d{10}")) && !IsBlank(TextInput1.Text),
RGBA(255, 0, 0, 1), /* <-- If not match, border color turn into red */
RGBA(0, 18, 107, 1)
)

Note: I assume that the digit of your telephone number is 10.

Re: Validate telephone number

Hi there,

 

Your function will depend on the format you want!

In the case you want this format : "XXXXXXXXXX", you can put the following code on your BorderColor Statement

If( 
Not(
IsMatch(YourTextBox.Text;Digit & Digit & Digit & Digit & Digit & Digit & Digit & Digit & Digit & Digit)
);
RGBA(255; 0; 0; 1)
)

In the case you want this format : "XX XX XX XX XX", you can put it

If( 
    Not(
        IsMatch(YourTextBox.Text;
Digit & Digit & Match.Space & Digit & Digit & Match.Space & Digit & Digit & Match.Space & Digit & Digit & Match.Space & Digit & Digit) ); RGBA(255; 0; 0; 1) )

Best regards my friend.

If you want to validate the passport number to not have any space or special characters such as !@#%^*(" in the text input, please modify above formula as below:

If(
Not(IsMatch(TextInput1.Text, "[a-zA-Z0-9]*"))&&!IsBlank(TextInput1.Text),
RGBA( 255, 0, 0, 1 ),
RGBA(0, 18, 107, 1)
)
