Don't Understand This

[F.Danials]

Hiya,

I made this script years ago, and now don't understand what is happening.
I wondered if someone would be so kind as to recode it using proper variable names etc instead of just using names like $k and $p (I know these names are bad, and I no longer do this. But like I said it was a long time ago since I coded this ).

Also, how do you output the appropriate error messages next to the correct field within the form?

Is there a better way of doing this?

<?php
$post = array("name" => "", "email" => "", "phone" => "");
$errors = $post;

if (isset($_POST["submit"])) {
	foreach ($post as $k => $v)
		$post[$k] = stripslashes($_POST[$k]);

	if ($post["name"] == "")
		$errors["name"] = "error";
	if (!preg_match('/[^@]+@[^.]+(\.[^.]+)+/', $post["email"]))
		$errors["email"] = "error";
	if ($post["phone"] == "")
		$errors["phone"] = "error";

	$error = false;
	foreach($errors as $k => $v) {
		if ($errors[$k] != "")
			$error = true;
	}

	if (!$error) {
		$message = "";
		foreach($post as $k => $v)
			if ($v != "")
				$message .= "$k: $v\n";
		$sent = mail("info@company.com", "Subject", $message, "From: info@company.com");
	}
}
?>

<form name="form" method="post" action="">
  SECTION #1<br>
<br>
  Name: 
  <input name="name" type="text" id="name">
  <br>
<br>
  E-Mail:
  <input name="email" type="text" id="email">
  <br>
<br>
  Phone:
  <input name="phone" type="text" id="phone">
  <br>
  <br>
  <input name="send" type="submit" id="send" value="Send">
  <input name="reset" type="reset" id="reset" value="Reset">
</form>

k is often used to stand for key
v for value

you could also have k stand for html_form_field_name

 Name: 
  <input name="name" type="text" id="name"> <?php echo $errors['name']; ?>
  <br>

Thanks crmalibu!
Is there a better way this can be coded, also how do I display the error message stored in $errors['fieldname'] variables next to the appropriate fields?

Also, what is actually happening in the script? I can't remember. Without being too cheeky, would it be possible for you to comment it?

I just wish I could remember!

also how do I display the error message stored in $errors['fieldname'] variables next to the appropriate fields?

Look at crmalibu's answer again.
