currently I have a website with a basic login, I was just wondering how I would display a the name,skill and description of the unique user who is logged in.This is what I have done so far.I can only find articles on how to display data into table.This is the updated code:
<?php
include('session.php');
require 'config.php';
$sql = "SELECT * FROM profile";
$result = $conn->query($sql);
//echo "id: " . $row["id"]. " - Name: " . $row["firstname"]. " " . $row["lastname"]. "<br>";
?>

<div id="Info">

<!--<span>James</span>-->
</p>
<p>
<strong>Skill:<?php echo $row["skill"]?><</strong>
<!--span>James</span>-->
</p>
<!-- <p>
<strong>review:<?php /*echo $row["review"]*/?><</strong>

</p> -->
<p>
<strong>Description:<?php echo $row["description"]?><</strong>
<span>James</span>
</p>
<!--<p>
<strong>Name:</strong>

</div>
<!-- Needed because other elements inside ProfilePage have floats

</div>
</body>
</html>
when the user successfully loggedin create a cookie and store their username or email whatever you used in that cookie. You have to do this stuff in your login.php file where you checks for username and password.
if(login success)
{
setCookie("username",value of username that you got from
user,'time()+3600','/');
echo "login successful";
}
After that in Profile you have write code like this;
<?php
$name=$_COOKIE['username'];
$sql=$conn->prepare("SELECT * from profile where username=?");
$stmt->bind_param('s', $name); // 's' specifies the variable type =>'string'
$stmt->execute();
$result = $stmt->get_result();
while ($row = $result->fetch_assoc()) {
// do something with $row
}
?>
After that you can display the inforamtion in your div like $row['username'] etc.
if $row[] come from a sql request, just add in your request something like :
$user = (...) your current user logged
(...)
select (...) where user = $user
You can use $_SESSION to identify people after login and store information about the person. A session variable saves data of a specific user across multiple pages.
A session id is stored in the user browser and that is used to identify the $_SESSION data of a person.
In your program you can easily do something like this:
<?php
session_start(); //before anything else
include('session.php');
require 'config.php';
$sql = "SELECT * FROM profile";
$result = $conn->query($sql);
//assuming $row contains the information from
$_SESSION["user"] = $row;
?>
<html>
<head>
<link rel="stylesheet" type="text/css" href="profile.css">
</head>
....
....
Now on another page, you could easily:
<?php
session_start();
if(isset($_SESSION["user"]) {
//logged in
$name = $_SESSION["user"]["name"];
} else {
//not logged in
}
?>
<html>
....

Hey there stackoverflow users, i have come upon a very confusing problem that I cant seem to move past. I am creating a forum type web page and am currently working on the comments section. I have a form that uses the post method to send your comment as well as a hidden input to store the threads ID. I will post the entire php file below just to make sure nothing is left out.
<?php
session_start();
parse_str($_SERVER['QUERY_STRING'], $link);
$threadID = $link['ID'];
require("config.php");
$connection = mysqli_connect($host, $user, $password, $database);
$error = mysqli_connect_error();
if($error != null) {
$output = "<p>Unable to connect to database!</p>";
exit($output);
} else {
//Get Thread Data
$query = "SELECT username, title, content FROM threads, users WHERE threads.ID = $threadID AND users.ID = threads.makerID;";
$results = mysqli_query($connection, $query);
$row = mysqli_fetch_assoc($results);
//Get Comment Data
$query = "SELECT username, comment FROM comments, users WHERE threadID = $threadID AND users.ID = comments.makerID;";
$results = mysqli_query($connection, $query);
$row = mysqli_fetch_assoc($results);
}
?>

The error is occurring under the main portion where i check if a user is logged in, and if they are add a short form consisting of a message, a text area, and a submit button. This form sends the information to the following php file.
<?php
session_start();
if(!isset($_SESSION['login_user'])) { header("location: main.php"); }
?>
<!DOCTYPE html>
<html>
<body>
<?php
require("config.php");
$connection = mysqli_connect($host, $user, $password, $database);
$error = mysqli_connect_error();
if($error != null) {
$output = "<p>Unable to connect to database!</p>";
exit($output);
} else {
//Validation
if ($_SERVER["REQUEST_METHOD"] == "POST") {
$comment = $_POST['comment'];
$threadID = $_POST['threadID'];
$user = $_SESSION['login_user'];
} else {
//Redirect back to register
echo"<p>Form must use post or input was bypassed.</p>";
echo" Return to home page. ";
mysqli_close($connection);
exit();
}
There is no issue with connecting to the database, and I don't believe the remainder of the code is necessary to help me with this error since that one if statement of checking if the form is using post is failing and the else statement is always called. Why is this? i have rewritten the form multiple times ensuring that its properly structured and using post yet it fails every time!
This question already has answers here:
How can I get an unknown username given an ID?
(2 answers)
Closed 1 year ago.
i am new to this field and this is the first time i am working with session, the question may seem very basic but would appreciate if someone could help me. Currently I have made a login and logout page using session and wish to display data of the particular user who has logged in. The user is redirected to retailer_login.php after they sign in, apart from login form there are 4 pages for the entire login and logout process.
retailer_login.php, retailer_session.php, retailer_profile.php, retailer_logout.php
Every page is working fine however i am able to display only single data column of the user from database but i wish to display the entire information that is stored about that specific user.

right now i am only able to use $login_session in order to display email on profile page. Can anyone please tell my how to display other data of the logged in user on the retailer_profile page through session
Just create another variables about current logged in user:
$row = mysql_fetch_assoc($ses_sql);
$login_session =$row['email'];
// another user data
$user_name = $row['name'];
$user_country = $row['country'];
$user_city = $row['city'];
$user_state = $row['state'];
$user_occupation = $row['occupation'];
Or you can just use one variable which shouldn't be overwritten:
$user_data = $row;
And then somewhere in script:
echo $user_data['city']; // etc...
Need to make $courseInfo and $row global so that they can be used for printing the row details in the header DIV.
Don't have a clue how to do this. Any help would be great.
<?php

$ID = mysql_real_escape_string($_REQUEST['ID']);
// Check the Course ID exists
$courseCheck = mysql_query("SELECT * FROM Courses WHERE CourseID = '".$ID."'");
if (mysql_num_rows($courseCheck) == 1) {
$checkMember = mysql_query("SELECT * FROM CourseMembers WHERE CourseID = '".$ID."' AND UserID = '".$_SESSION['UserID']."'");
if (mysql_num_rows($checkMember) == 1) {

I think they're already global. "PHP does not have a block-level scope."
You could store them in session variables, similarly to your $_SESSION['LoggedIn']
You could also use php variable $GLOBALS for making your variables visible in all scopes but I would not recommend it for this kind of task. Also, beware - $GLOBALS contains superglobals like $_POST and $_GET, you should keep that in mind, when ie. iterating over it. Furthermore - when you can access $_GET and $_POST in functions, that have smaller scope you still have to use $GLOBALS to access custom ones.
Example for this kind behaviour:
<?php
error_reporting(-1);
$GLOBALS['_customVar'] = 'foobar';
$GLOBALS['_GET']['id'] = 'myId';
function myFnc() {
echo $_customVar;
}
function myFnc2() {
echo $_GET['id'];
}
myFnc();
myFnc2();
?>
I wish to set the title of my webpage to Ultan.me - Whatever the post title. I want it to display the post title. The posts are submitted to a MySQL database and the title row is called "title". Any help is appreciated with this small question.
Update:
Here is the page itself now but it doesn't display the title. Should I open the php document and connect to my database somewhere different to it's current locations?

Here's the method I use (for similar things, not just title):
<?
ob_start (); // Buffer output
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">
<head>
<title><!--TITLE--></title>
</head>
<body>
<?
$pageTitle = 'Title of Page'; // Call this in your pages' files to define the page title
?>
</body>
</html>
<?
$pageContents = ob_get_contents (); // Get all the page's HTML into a string
ob_end_clean (); // Wipe the buffer
// Replace <!--TITLE--> with $pageTitle variable contents, and print the HTML
echo str_replace ('<!--TITLE-->', $pageTitle, $pageContents);

PHP usually works be executing any bits of code and printing all output directly to the browser. If you say "echo 'Some text here.';", that string will get sent the browser and is emptied from memory.
What output buffering does is say "Print all output to a buffer. Hold onto it. Don't send ANYTHING to the browser until I tell you to."
So what this does is it buffers all your pages' HTML into the buffer, then at the very end, after the tag, it uses ob_get_contents () to get the contents of the buffer (which is usually all your page's HTML source code which would have been sent the browser already) and puts that into a string.
ob_end_clean () empties the buffer and frees some memory. We don't need the source code anymore because we just stored it in $pageContents.
Then, lastly, I do a simple find & replace on your page's source code ($pageContents) for any instances of '' and replace them to whatever the $pageTitle variable was set to. Of course, it will then replace <title><!--TITLE--></title> with Your Page's Title. After that, I echo the $pageContents, just like the browser would have.
It effectively holds onto output so you can manipulate it before sending it to the browser.
Hopefully my comments are clear enough.
Look up ob_start () in the php manual ( http://php.net/ob_start ) if you want to know exactly how that works (and you should) :)
You parse the field from the database as usual.
Then let's say you put it in a variable called $title, you just
<html>
<head>
<title>Ultan.me - <?php echo htmlspecialchars($title);?></title>
</head>
EDIT:
I see your problem. You have to set $title BEFORE using it. That is, you should query the database before <title>...
header.php has the title tag set to <title>%TITLE%</title>; the "%" are important since hardly anyone types %TITLE% so u can use that for str_replace() later. then, you use output buffer like so
<?php
ob_start();
include("header.php");
$buffer=ob_get_contents();
ob_end_clean();
$buffer=str_replace("%TITLE%","NEW TITLE",$buffer);
echo $buffer;
?>
For more reference, click PHP - how to change title of the page AFTER including header.php?
What about using something like:
<?php
$page_title = "Your page tile";
include("navigation.php"); // if required
echo("<title>$page_title</title>");
?>
Move the data retrieval at the top of the script, and after that use:
<title>Ultan.me - <?php echo htmlspecialchars($title, ENT_QUOTES, 'UTF-8'); ?></title>
You need to set the value of $title before echoing it.
Also, you should really sanitize any data before using it in queries as this is a security risk
create a new page php and add this code:
<?php
function ch_title($title){
$output = ob_get_contents();
if ( ob_get_length() > 0) { ob_end_clean(); }
$patterns = array("/<title>(.*?)<\/title>/");
$replacements = array("<title>$title</title>");
$output = preg_replace($patterns, $replacements,$output);
echo $output;
}
?>
in <head> add code: <?php require 'page.php' ?> and on each page you call the function ch_title('my title');
The problem is that $title is being referenced on line 5 before it's being assigned on line 58. Rearranging your code isn't easy, because the data is both retrieved and output at the same time. Just to test, how does something like this work?
Because you're only retrieving one row, you don't need to use a while loop, but I left it with hopes that it'll make it easier for you to relate to your current code. All I've done is removed the actual output from your data retrieval, and added variables for category and category name which are then referred to as usual later on. Also, I haven't tested this. :)
It'll be tricky to rearrange your code to make this work, but I'll try :)
So, put this at the top of your code:
<?php require_once('mysql.php'); ?>
The top of the file should look like:
<?php require_once('mysql.php'); ?>
<html>
<head>
<meta name="keywords" content="Mac user Ultan Casey TheCompuGeeks UltanKC">
<title>Ultan.me - <?php echo htmlspecialchars($title); ?> </title>
Then, create a file called mysql.php in the same directory that the file which contains the code you quoted is in.
Put this is mysql.php:
<?php
mysql_connect ('localhost', 'root', 'root');
mysql_select_db ('ultankc');
if (!isset($_GET['id']) || !is_numeric($_GET['id'])) {
die("Invalid ID specified.");
}
$id = (int)$_GET['id'];
$sql = "SELECT * FROM php_blog WHERE id='$id' LIMIT 1";
$result = mysql_query($sql) or print ("Can't select entry from table php_blog.<br />" . $sql . "<br />" . mysql_error());
$res = mysql_fetch_assoc($result);
$date = date("l F d Y", $res['timestamp']);
$title = $res['title'];
$entry = $res['entry'];
$get_categories = mysql_query("SELECT * FROM php_blog_categories WHERE `category_id` = $res['category']");
$category = mysql_fetch_array($get_categories);
?>
Well, hope that helped :)
I know this is an old post but having read this I think this solution is much simpler (though technically it solves the problem with Javascript not PHP).
<html>
<head>
<title>Ultan.me - Unset</title>
<script type="text/javascript">
function setTitle( text ) {
document.title = text;
}
</script>
<!-- other head info -->
</head>
<?php
// Make the call to the DB to get the title text. See OP post for example
$title_text = "Ultan.me - DB Title";
// Use body onload to set the title of the page
print "<body onload=\"setTitle( '$title_text' )\" >";
// Rest of your code here
print "<p>Either use php to print stuff</p>";
?>
<p>or just drop in and out of php</p>
<?php
// close the html page
print "</body></html>";
?>
Simply add $title variable before require function
<?php
$title = "Your title goes here";
require("header.php");
?>
header.php
<title><?php echo $title; ?></title>
<?php echo APP_TITLE?> - <?php echo $page_title;?>
this should work fine for you
if you want to current script filename as your title tag
include the function in your project
function setTitle($requestUri)
{
$explodeRequestUri = explode("/", $requestUri);
$currentFileName = end($explodeRequestUri);
$withoutExt = preg_replace('/\\.[^.\\s]{3,4}$/', '', $currentFileName);
$explodeCurrentFileName = explode("-", $withoutExt);
foreach ($explodeCurrentFileName as $curFileValue)
{
$fileArrayName[] = ucfirst($curFileValue);
}
echo implode(" ", $fileArrayName);
}
and in your html include the function script
and replace your title tag with this
<title>Your Project Name -
<?php setTitle($_SERVER['REQUEST_URI']); ?>
</title>
it works on php7 and above but i dont have any idea about php 5.*
Hope it helps
