Input Box with Masking

[ddtpmyra]

How can you do input mask inside PHP let say I wanted to input a phone number with this format below:

(123) 4756-7890

There's no mask. What do you mean by input mask?

A phone number is typically a string of numbers. It should be stripped from all other characters when PHP deals with it (ie put in database), only when presented, the presentation programmer should put the number back in the format desired.

 
$cleanPhone = preg_replace("/[^0-9]/","",$_POST['phone']); 
 
 

Thanks,

Hi Dan,

This is for inputing not saving the numbers on the database. Usually users are confused if they need to put dashes and parenthesis on the form.. But to make it uniform I wanted to put this masking on the text box. How can I do this?

@ddtpmyra
since PHP is executed on the server it cannot interact with the user's input. you can use a default value for the input field as "mask" together with some styling. or even a background image seems possible. further enhancements can be applied through Javascript.
