Validate telephone number

[Anonymous]

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.

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.

Hi @Anonymous ,

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:

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.

Hi @Anonymous ,

Do you want to validate the passport number to not have any space or special characters such as !@#%^*(" in the text input?

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)
)

Best regards,
