我正在使用PHP注册表单。表单是一个div，当您单击按钮时会打开该表单。这是我的代码：
day = 'something that isnt int'这一切都在我的表单提交后执行：
if(!$fieldsFilled){
$unfilledFormsError = '<br><font class="text-error" id="unfilled-forms-error">One of more of the fields are empty.</font><br>';
echo "
<script type='text/javascript'>
$(document).ready(function(){
$('#home-sign-up-box').show();
console.log('test passed');
});
</script>";
}
完整的PHP代码：
if (isset($_POST['signUp']))
HTML注册div /表单代码：
<?php require 'dbconnect.php'; ?>
<?php
//Error message variable declarations
$unmatchedPasswordsError = "";
$unfilledFormsError = "";
$emailError = "";
//If sign up submit POST recieved
if (isset($_POST['signUp']))
{
//Start session
session_start();
$email = $connection->real_escape_string($_POST['suEmail']);
$result = mysqli_query($connection, "SELECT * FROM users WHERE email='".$email."'");
if ($result->num_rows)
{
$emailInUse = true;
}
else
{
$emailInUse = false;
}
//Search for empty fields
$required = array('suFirstName', 'suLastName', 'suEmail', 'suPassword', 'suVerifyPassword', 'suDisplayName');
$fieldsFilled = true;
foreach($required as $field)
{
if (empty($_POST[$field]))
{
$fieldsFilled = false;
}
else
{
$fieldsFilled = true;
}
}
if ($emailInUse)
{
$emailError = "The email is already in use.";
echo "
<script type='text/javascript'>
$(document).ready(function(){
$('#home-sign-up-box').show();
});
</script>";
}
else
{
if(!$fieldsFilled)
{
$unfilledFormsError = '<br><font class="text-error" id="unfilled-forms-error">One of more of the fields are empty.</font><br>';
echo "
<script type='text/javascript'>
$(document).ready(function(){
$('#home-sign-up-box').show();
console.log('test passed');
});
</script>";
}
else
{
if (!filter_var($email, FILTER_VALIDATE_EMAIL))
{
$emailError = "The email is not valid.";
echo "
<script type='text/javascript'>
$(document).ready(function(){
$('#home-sign-up-box').show();
});
</script>";
}
else
{
//Check for unverified password
if ($_POST['suPassword']!= $_POST['suConfirmPassword'])
{
$unmatchedPasswordsError = "The passwords do not match.";
echo "
<script type='text/javascript'>
$(document).ready(function(){
$('#home-sign-up-box').show();
});
</script>";
}
else
{
//Variable declaration for sign up POST values
$suFirstName = $_POST['suFirstName'];
$suLastName = $_POST['suLastName'];
$suEmail = $_POST['suEmail'];
$suPassword = $_POST['suPassword'];
$suDisplayName = $_POST['suDisplayName'];
//Insert POST values into database
$sql = $connection->query("INSERT INTO users (firstName,lastName,email,password,displayName)Values('{$suFirstName}','{$suLastName}','{$suEmail}','{$suPassword}','{$suDisplayName}')");
//Redirect to 'email sent' webpage
header('Location: emailSent.php');
}
}
}
}
}
//If log in submit POST recieved
if (isset($_POST['logIn']))
{
//Variable declaration for log in POST values
$liEmail = $_POST['liEmail'];
$liPassword = $_POST['liPassword'];
//Search for log in credentials in dabase
$result = $connection->query("select * from users where email = '$liEmail' AND password = '$liPassword'");
$row = mysqli_fetch_array($result, MYSQLI_BOTH);
//TODO: CHECK FOR REMEMBER ME CHECK
session_start();
$_SESSION['userID'] = $row['userID'];
}?>
