PHP - Check For Phone Numbers In Textarea Using Php

Can someone advise the edit required to include validation of US phone numbers ($phone_number3) when entered with no spaces between the area code and/or prefix.

Note: I have working code (regular expression) that validates phone numbers that enclose the area code with parenthesis or having a space, hyphen, or dot between area code, prefix, or last four digits.

Examples:  all three shown below are validated based on regular expresion
(123) 456-7890
123.456.7890
123 456 7890

However, I want to also include the option for 1234567890 (phone number have NO spaces) as valid.

I know the edit will be within ( |-|.)  using the PIPE but not sure how to denote the "no space" syntax within the regular expression.

See the regular expression: $good_phone = "^\(?[0-9]{3}\)?( |-|.)[0-9]{3}(-|.)[0-9]{4}$";

and if you wan to view the entire php snippet


// function which validates an American phone number

function validate_phone($phone_number) {
   $good_phone = "^\(?[0-9]{3}\)?( |-|.)[0-9]{3}(-|.)[0-9]{4}$";

   if (preg_match("/$good_phone/", $phone_number)) {
  echo "$phone_number is valid.<br/>";
   }
   else echo "$phone_number is NOT valid.<br/>";
}

$phone_number1 = "123.456.7890";
validate_phone($phone_number1);

$phone_number2 = "(123) 456-7890";
validate_phone($phone_number2);

$phone_number3 ="1234567890";
validate_phone($phone_number3);

Hey.

I been using a function to check if a string contains only letters which is:

ctype_alpha

But i would like to change it to allow numbers 0 to 9 and the letters is there a function to do that in PHP i can't find it.

Hi, I have a form containg three text inputs and one text area.  On the php page that processes the form, I want to check first to make sure the user entered something (input field is not empty) before processing the form. I'll just provide a skeleton of form processing page below. *(I'm save space and time by omitting the form itself but he text inputs fields have the following name attributes "name", "company", "email",  and the textarea field's name attribute is  "message" )  I'll do my best to explain the code in further detail within the code comments.


Code: [Select]




<?php




//Turn on output buffering. Allows for headers to be called anywhere on script. See pg228 Ulman.

         $c = FALSE;

So there it is. Everything works fine except that the part which checks if the textarea (named "message") is empty, doesn't work.   If I click the submit button without filling out any field, the appropriate error messages are printed for the text input fields but not the text area field.  If I fill out all fields correctly and leave the "message" field blank, the form gets processed correctly and values are placed in the database and the success message is printed out.  This is also the case when I enter a value for "message" textarea field.  Now I tried something.  I changed the textarea to a text field and the $_SESSION['message'] variable finally got echoed when I left this field blank.  So apparently, the problem arises from the fact that the named attribute from a textarea tag is not being processed correctly??  Who knows what's going wrong here?

Hi i would like to know what is the best way to check if a textarea or an input box is empty.
Is the empty function effective?
