I'm creating a link sharing website and I want the user that registers to upload an avatar and use that avatar throughout the website.
I got so far that the user can register but can't find a way for him/her to have an avatar.
Here I have the signup.php (for the users to register in) file so that you can see what I mean.
<?php
include 'connect.php';
include 'header.php';
echo '<h3>Register</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="">
<b>Username: </b><input type="text" name="user_name" /><br/><br/>
<b>Password: </b><input type="password" name="user_pass"><br/><br/>
<b>Confirm assword: </b><input type="password" name="user_pass_check"><br/> <br/>
<b>E-mail: </b><input type="email" name="user_email"><br/><br/>
///////////////////////////////////////////////////////////
///////// must I use <input type="file"> here???? /////////
///////// and how do I put it in the database???? /////////
///////////////////////////////////////////////////////////
<input type="submit" value="Join" />
</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['user_name']))
{
//the user name exists
if(!ctype_alnum($_POST['user_name']))
{
$errors[] = 'The username can only contain letters and digits.';
}
if(strlen($_POST['user_name']) > 30)
{
$errors[] = 'The username cannot be longer than 30 characters.';
}
}
else
{
$errors[] = 'The username field must not be empty.';
}
if(isset($_POST['user_pass']))
{
if($_POST['user_pass'] != $_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
$sql = "INSERT INTO
users(user_name, user_pass, user_email ,user_date, user_level)
VALUES('" . mysql_real_escape_string($_POST['user_name']) . "',
'" . sha1($_POST['user_pass']) . "',
'" . mysql_real_escape_string($_POST['user_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 sharing links.';
