On my index page i have my login form for users, then it goes to login.php to handle the login script, from there the users are redirected to dashboardd.php. But i want it to to be so that they have to be logged in to access this page, and not just type in the URL.
Index.php
<?php
session_start();
?>
<?php
if( isset($_SESSION['ERRMSG_ARR']) && is_array($_SESSION['ERRMSG_ARR']) && count($_SESSION['ERRMSG_ARR']) >0 ) {
echo '<ul style="padding:0; color:red;">';
foreach($_SESSION['ERRMSG_ARR'] as $msg) {
echo '<li>',$msg,'</li>';
}
echo '</ul>';
unset($_SESSION['ERRMSG_ARR']);
}
?>

$result->execute();

if($errflag) {
$_SESSION['ERRMSG_ARR'] = $errmsg_arr;
session_write_close();
header("location: index.php");
exit();
}
?>
dashboard.php
<?php
echo "string";
?>
Make a $_SESSION e.g. $_SESSION['logged_in'] and fill it with data or set it to true
$username = $_POST['username']; //don't forget to sanitize $_POST values
$userID = (int)$_POST['userID'];
$_SESSION['logged_in'] = array('username' => $username, 'id' => $userID);
OR
$_SESSION['logged_in'] = TRUE;
And then check on the dashboard
if(!isset($_SESSION['logged_in'])){
header('Location:index.php');
}
Now if it does not exists, it will return the user to index.php. Don't forget to use session_start() at the top of every page where you want to call the $_SESSION variables.
You can set an array() in a $_SESSION, so this is ideal for storing user info. Do not store user passwords in a $_SESSION tho.

I've written some code to create a contact form, however I have attempted to validate the email field and when I test using dummy data with incorrect email the function I use (filter_var($email, FILTER_VALIDATE_EMAIL)) does not get processed. I've added all my php and html code together in one file for easier readability and not to complicate things.
Here is my full code:
<?php
// define variables and set to empty values
$first_nameErr = $last_nameErr = $emailErr = $messageErr = "";
$first_name = $last_name = $email = $from = "";
if($_SERVER["REQUEST_METHOD"] == "POST"){
$to = "pdgcaracas#gmail.com"; // this is your Email address
// this is the sender's Email address
$first_name = $_POST['first_name'];
$last_name = $_POST['last_name'];
$from = $_POST['email'];
$subject = "Form submission";
$subject2 = "Copy of your form submission";
$message = $first_name . " " . $last_name . " wrote the following:" . "\n\n" . $_POST['message'];
$message2 = "Here is a copy of your message " . $first_name . "\n\n" . $_POST['message'];
$headers = "From:" . $from;
$headers2 = "From:" . $to;
if (empty($_POST["first_name"])){
$first_nameErr = " First name is required";
}
else if ((!preg_match("/^[a-zA-Z-' ]*$/",$first_name))) {
$first_nameErr = "Please type in only letters and whitespace";
}
else if(empty($_POST["last_name"])){
$last_nameErr = " Last name is required";
}
else if ((!preg_match("/^[a-zA-Z-' ]*$/",$last_name))) {
$last_nameErr = "Please type in only letters and whitespace";
}
else if (empty($_POST["email"])) {
$emailErr = "Email is required";
}
else if (filter_var($email, FILTER_VALIDATE_EMAIL)) {
$emailErr = "Email is invalid";
}
else if (empty($_POST["message"])) {
$messageErr = "message is required";
}
else {
mail($to,$subject,$message,$headers);
mail($from,$subject2,$message2,$headers2); // sends a copy of the message to the sender
echo '<script>alert("Mail Sent. Thank you , we will contact you shortly.")</script>';
}
// You can also use header('Location: thank_you.php'); to redirect to another page.
}

filter_var returns true only if the provided $email is valid.
To check if the email is invalid, change the if statement of filter_var as following and it should work
//your code
if (!(filter_var($email, FILTER_VALIDATE_EMAIL))) {
$emailErr = "Email is invalid";
}
//your code
im working on my crud skills, but im having some trouble. the first page shows a list of all blog posts, when the user clicks on read more it sends the specific posts id through the url and is recieved by the destination page which uses that id to display the single post/ heres the code for that part. it actually works fine
function display_single_post($title,$author,$date,$image,$content){
$main_page_blog_html = "<h2>
<a href='#'>%s</a>
</h2>
<p class='lead'>
by <a href='index.php'>%s</a>
</p>
<p><span class='glyphicon glyphicon-time'></span> Posted on %s</p>
<hr>
<img class='img-responsive' src='images/%s'>
<hr>
<p>%s</p>
<hr>
<hr>";
printf("{$main_page_blog_html}",$title,$author,$date,$image,$content);
if(isset($_GET["id"])){
$id = $_GET["id"];
$stmt = $connect->link->query("SELECT * FROM posts WHERE post_id = $id");
while($row = $stmt->fetch()){
$post_title = $row["post_title"];
$post_author = $row["post_author"];
$post_date = date('F j, Y \a\t g:ia', strtotime( $row["post_date"] ));
$post_image = $row["post_image"];
$post_content = $row["post_content"];
$id = $row["post_id"];
display_single_post($post_title,$post_author,$post_date,$post_image,$post_content);
}
}
like i said this all works fine. the get value is recieved and loads the post. the problem is when i try to use that $_get id in a query to insert a comment. all this code is on the one page im just showing the php without the html. anyway heres the code to insert the comment
if(isset($_POST["create_comment"])){
global $connect;
$post_id = $_GET["id"];
$comment_author = $_POST["comment_author"];
$author_email = $_POST["author_email"];
$comment_content = $_POST["comment_content"];
$comment_status = "pending";
edit with all the code

Based on your code and your comments, I assume the page is called post.php and when you first reach the page it has the id on the url like this: post.php?id=156.
But once you submit the comments' form, since the action for said form it is simply post.php you're losing the id.
You could add the id on the action after post:
<form role="form" method="post" action="post.php?id=<?php echo $id; ?>">
or add a hidden input with the id:
<input type="hidden" name="id" value="<?php echo $id; ?>">
But then you'd have to reach it with $_POST
Another option is to use the SELF for the action like this:
<form role="form" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
This will retain the id but also any other get variables you may have on the url.
//EDIT
This is a simplification of the probelm which is working, if you visit post.php?id=456 (or any number) and then press Submit, you get the proper response:
<!-- First Blog Post -->
<?php
if(isset($_POST["create_comment"])){
$post_id = $_GET["id"];
echo "The id is: $post_id";
// gets comment and inserts into the db
}
if(isset($_GET["id"])){
$id = $_GET["id"];
// calls display_single_post
}
?>
<!-- Comments Form -->
<div class="well">
<h4>Leave a Comment:</h4>
<form role="form" method="post" action="post.php?id=<?php echo $id; ?>">
<button type="submit" name="create_comment" class="btn btn-primary">Submit</button>

I am trying to redirect the page using header("location: profile.php") after I click a submit button in the login form, but the page won't redirect. The username and password just gets submitted somewhere.
Here is my main page:
<?php
include ($_SERVER["DOCUMENT_ROOT"]."/example/login.php");
if(isset($_SESSION['login_user'])){
header("location: profile.php");

$conn = new mysqli($server, $username, $password, $database);
// To protect MySQL injection for Security purpose
$username = stripslashes($username);
$password = stripslashes($password);
//$username = mysql_real_escape_string($username);
//$password = mysql_real_escape_string($password);
// Selecting Database
//$db = mysqli_select_db("noteshare", $conn);
// SQL query to fetch information of registerd users and finds user match.
$qry="select * from signin where password='$password' AND username='$username'";
$query = mysqli_query($conn,$qry);
$rows = mysqli_fetch_row($query);
if ($rows == 1) {
$_SESSION['login_user']=$username; // Initializing Session
header("Location:http://localhost.com/profile.php", true, 301); exit;// Redirecting To Other Page
} else {
$error = "Username or Password is invalid";
}
mysqli_close($conn); // Closing Connection
}
}
?>
function mysqli_fetch_row returns an array or NULL. Therefore
if ($rows == 1)
is never true and you won't reach the redirect with header().
You can use i.e if (is_array($rows)) or if (isset($rows))
You can always insert a var_dump($rows) for debugging to see what the variable $rows looks like.
Note, HTTP code 301 is a permanent redirect. It should be 302. Or simply you can omit the second and third argument of the header() function and it will be a 302.
Did your connection with mysql is ok, then try this,
header('Location:filename');
Eg: header('Location:test1.php');
Try this
header("Location:profile.php"); die();
OR redirect with JS
echo '<script>window.location.href = "profile.php";</script>' ;
You are using an absolute URL. TLD .com is not used when working on a local server.
Change:
header("Location:http://localhost.com/profile.php");
To:
header("Location:http://localhost/profile.php");
It should work!
I am trying to create a login form, in that login form I am using fetch_array() method to fetch the fields that user enter,but it showing some errors:
Login.php
<?php
include ("Connection.php");
?>
<?php
if(isset($_POST['Login']))
{
$Em = $_POST['form-email'];
$Pw = $_POST['form-password'];
$result = $con->query("SELECT * FROM userdetails where Email='$Em' Password='$Pw'");
$row = $result->fetch_assoc(MYSQLI_BOTH);
session_start();
$_SESSION["UserID"] = $row['UserID'];
header('Location: index.php');
}
?>

This is login form and index.php, I already created register form it working perfectly, the data that I registered is stored correctly, but the problem is in login form, it is redirection to index page, and the error is:
Fatal error: Call to a member function fetch_assoc() on a non-object in C:\xampp\htdocs\Studentmanagementsys\Login.php on line 13
You have syntax error in your sql query. When you executing query by mysqli, if there some sql syntax errors, method $con->query(...) will return boolean false. So, you have false value in your $result.
Php cant call method on boolean value: $result->fetch_assoc(), cause boolean is scalar value, not object. (sorry for my english)
I am trying to display the code of a php file as plain html. This is all going well except for that fact that I would like it to 'open up' the <?php require 'Main_content_bar.php'; ?> statements aswell.
So far I have show_source($page); correctly working.
It currently prints:
<?php require 'Main_content_bar.php'; ?>

However, as one can see, the contents of the require statements do not show. I cannot for the life of me work out how to do this.
So what it would end up looking like is something like this:

Note the lack of require statements
You cannot do that with show_source, which just "show some code sources" of a file.
You need to create your own function which take a filename in argument, then you have to analyze the source like this:
replace all require/include/require_once/include_once (what do I forget?) by their own content
make the function recursive (because Main_content_bar.php can have other include inside it)
Use highlight_string at the end of your function.
EDIT to search & replace, one way (there is several) is to use preg_match_all. That part of the code would look like this :
$new_content = file_get_contents('your-file.php');
$base_path = __DIR__.'/';
// pattern to find require, require_once, include, include_once functions
// and catch their arguments
$pattern = "#<\?php (?:require|include(?:_once)?)\s*'(.*)'; \?>#u";
if (preg_match_all($pattern, $new_content, $matches))
{
foreach($matches[0] as $pattern_index => $full_pattern)
{
$file = $matches[1][$pattern_index];
$subcontent = file_get_contents($base_path.$matches[$pattern_index]);
$new_content = str_replace($new_content, $full_pattern, $subcontent);
}
}
highlight_string($new_content);
