Quisiera saber si me puden ayudar a poder mejorar este codigo que tengo de un registro de usuarios.
Quiero que cuando haga click en el boton aparezca los campos de texto en color rojo y un mensaje de error.
Este es mi codigo:
Código PHP:
<?php
//signup.php
include 'connect.php';
include 'header.php';
echo '<h3>Sign up</h3><br />';
if($_SERVER['REQUEST_METHOD'] != 'POST')
{
/*the form hasn't been posted yet, display it
note that the action="" will cause the form to post to the same page it is on */
echo '<form method="post" action="">
Username: <input type="text" name="usuario" /><br />
Password: <input type="password" name="password"><br />
Password again: <input type="password" name="user_pass_check"><br />
E-mail: <input type="email" name="email"><br />
<input type="submit" value="Registrarme" />
</form>';
}
else
{
/* so, the form has been posted, we'll process the data in three steps:
1. Check the data
2. Let the user refill the wrong fields (if necessary)
3. Save the data
*/
$errors = array(); /* declare the array for later use */
if(isset($_POST['usuario']))
{
//the user name exists
if(!ctype_alnum($_POST['usuario']))
{
$errors[] = 'The username can only contain letters and digits.';
}
if(strlen($_POST['usuario']) > 30)
{
$errors[] = 'The username cannot be longer than 30 characters.';
}
}
else
{
$errors[] = 'The username field must not be empty.';
}
if(isset($_POST['password']))
{
if($_POST['password'] != $_POST['user_pass_check'])
{
$errors[] = 'The two passwords did not match.';
}
}
else
{
$errors[] = 'The password field cannot be empty.';
}
if(!empty($errors)) /*check for an empty array, if there are errors, they're in this array (note the ! operator)*/
{
echo 'Uh-oh.. a couple of fields are not filled in correctly..<br /><br />';
echo '<ul>';
foreach($errors as $key => $value) /* walk through the array so all the errors get displayed */
{
echo '<li>' . $value . '</li>'; /* this generates a nice error list */
}
echo '</ul>';
}
else
{
//the form has been posted without, so save it
//notice the use of mysql_real_escape_string, keep everything safe!
//also notice the sha1 function which hashes the password
$sql = "INSERT INTO
usuarios(usuario,password, email ,fecha_registro, usuario_nivel)
VALUES('" . mysql_real_escape_string($_POST['usuario']) . "',
'" . sha1($_POST['password']) . "',
'" . mysql_real_escape_string($_POST['email']) . "',
NOW(),
0)";
$result = mysql_query($sql);
if(!$result)
{
//something went wrong, display the error
echo 'Something went wrong while registering. Please try again later.';
//echo mysql_error(); //debugging purposes, uncomment when needed
}
else
{
echo 'Succesfully registered. You can now <a href="signin.php">sign in</a> and start posting! :-)';
}
}
}
include 'footer.php';
?> Gracias.
