Step 1: Create E-Mail Form

Here is a sample html email form

<form action=”" method=”post”>
Name: <br>
<input type=”text” name=”name”>
<br>
Email: <br>
<input type=”text” name=”email”>
<br>
Subject: <br>
<input type=”text” name=”subject”>
<br>
Text:<br>
<textarea name=”message” cols=”" rows=”"></textarea><br>
<input type=”submit” name=”submit” value=”Send”>
<input type=”reset” name=”Reset” value=”Reset”>
</form>

Copy the html code above and past it into a file with the name contactus.php

Now its time to add the php code.

Step 2: Sending the data

We will first check to see if the form was submitted then we will check to see if all fields were filled in. If all is well, we well send each form data to it’s perspective variables (indicated by the sign “$”) and send out the email with a successful message. If all field were not filled-in, then display an error message. The php code is below.

<?php
if ($submit) { // if the form was sent do the following

if($name && $subject && $email && $message ) { // if all fields were filled-in send email
mail(“you@youraddress.com”,”$subject”,”$message”,”From: $name <$email>”) or die(“email error”);
echo “Message Sent”; // if all went well, display message was sent
} else {
echo “All fields must be filled in!<BR>”; // if not all were filled in, display error message
}
} // end php submission code
?>

Now just copy and past the php code above into the “contactus.php” file. You can place it anywhere inside the body tag and it will work just fine.

Question: How to validate number values to and block all letters and symbol in a form.

Answer: You can check the value or convert the value to an integer (number).

1) Check a value using is_int() to finds whether the given variable is an integer

<?
if(is_int($variable))
echo "Pass test";
else
echo "Please use only numbers";
?>

2) Note: To test if a variable is a number or a numeric string (such as form input, which is always a string), you must use is_numeric().

<?
if(is_numeric($variable))
echo "Pass test";
else
echo "Please use only numbers";
?>

3) Convert the value to an integer (number) using settype.

<?php
$foo = "5bar"; // string
$bar = true; // boolean

settype($foo, “integer”); // $foo is now 5 (integer)
settype($bar, “string”); // $bar is now “1″ (string)
?>

or you can use int to do the trick.


<?
$int=593; // $int is a integer
$int.=""; // $int is now a string
?>


To view all of the POST/GET Variables, you could use the following PHP statements.

NOTE: Make sure that “REGISTER_GLOBALS” are turned ON and DO NOT USE (enctype=”text/plain”) in your form tag or you may not be able to retrieve the posted values.

<? 
print_r($_POST); 
// or
print_r($_GET);
?>

or you may want to see all POST/GET variables including global variables like cookies set by your web site.

<?
print_r($_REQUEST);
?>

Here is a sample as to how the data will display after posting your form by using the above PHP statements:

<? Array ( [textfield1] => Alexander [textfield1] => 1 [submit] => Submit ) ?>

If you would like to change the way your POST/GET Array variables are displayed, you could do the following:

<?
echo "POST/GET Variables:";
foreach ($_GET as $key => $val)
echo "$key =$val";
?>

The the code above should display something like this:

POST/GET Variables:
textfield =Mike
textfield2 =Tome
textfield3 =Sue
textfield4 =Bob
Submit =Submit
