Validation/insert problem

witchy478 · March 18, 2012

Hi

My problem is that I can't insert my information into my database. I was able to insert the information into my database last night but when I tried to use validation it's not working any more.

Here is my code for the sign up

<?php
require_once("validation.php");
?>

<div id="container">
	<h1>Registration process</h1>

	<?if( isset($_POST['send']) && (!validateName($_POST['name']) || !validateEmail($_POST['email']) || !validatePasswords($_POST['pass1'], $_POST['pass2']) || !validateMessage($_POST['message']) ) ):?>
			<div id="error">
				<ul>
					<?if(!validateName($_POST['name'])):?>
						<li><strong>Invalid Name:</strong> We want names with more than 3 letters!</li>
					<?endif?>
					<?if(!validateEmail($_POST['email'])):?>
						<li><strong>Invalid E-mail:</strong> Stop cowboy! Type a valid e-mail please </li>
					<?endif?>
					<?if(!validatePasswords($_POST['pass1'], $_POST['pass2'])):?>
						<li><strong>Passwords are invalid:</strong> Passwords doesn't match or are invalid!</li>

			<div id="error" class="valid">
				<ul>
					<li><strong>Congratulations!</strong> All fields are OK </li>

	<form method="post" id="customForm" action="index.php">

<?php

echo "Successful";
echo "<BR>";
echo "<a href='insert.php'>Back to main page</a>";
}

else {
echo "ERROR";
}

// close connection 
mysql_close();
?>

This is the validation.php

<?php
function validateName($name){
	//if it's NOT valid
	if(strlen($name) < 4)
		return false;
	//if it's valid
	else
		return true;
}
function validateEmail($email){
	return ereg("^[a-zA-Z0-9]+[a-zA-Z0-9_-]+@[a-zA-Z0-9]+[a-zA-Z0-9.-]+[a-zA-Z0-9]+.[a-z]{2,4}$", $email);
}
function validatePasswords($pass1, $pass2) {
	//if DOESN'T MATCH
	if(strpos($pass1, ' ') !== false)
		return false;
	//if are valid
	return $pass1 == $pass2 && strlen($pass1) > 5;
}
function validateMessage($message){
	//if it's NOT valid
	if(strlen($message) < 10)
		return false;
	//if it's valid
	else
		return true;
}
?>

And this is the validation.js

I also get that the name, email and password is undefined

Your trying to use PHP functions in JavaScript. That aint going to happen.

trq · March 18, 2012

Scratch that. I missed the part where you define functions of the same name in JavaScript.

witchy478 · March 18, 2012

Do you know what I did wrong and how I can fix it

trq · March 18, 2012

Without a description of the problem, no.

witchy478 · March 18, 2012

the problem is that I get undefined name, undefined email and undefined password and the information doesn't get put into the database

witchy478 · March 18, 2012

I have managed to get the form to save the data but I still get the undefined name, undefined email and undefined password and now instead of saving one row it ends up saving a couple of rows. If that makes sense.

Here is the code I used for the form

If your getting undefined in your javascript it suggests you haven't set your id attributes within your input tags correctly. Without all the code I doubt we'll be able to draw a thorough conclusion.
