I am trying to display some variables and forms like a inbox type messages with "echo".
The problem is that the echo is not displayed and don't know how to repair it.
When i click on subject field on the subject title should show the "echo" but it doesn't.
Bellow is the code:
<?php
if(isset($_GET['msg_id'])){
$get_id = $_GET['msg_id'];
$sel_message = "select * from messages where msg_id='$get_id'";
$run_message = mysqli_query($con, $sel_message);
$row_message = mysqli_fetch_array($run_message);
$msg_subject = $row_message['msg_sub'];
$msg_topic = $row_message['msg_topic'];
$reply_content = $row_message['reply'];
//updating the unread message to read
$update_unread = "update messages set status='read' where msg_id='$get_id'";
$run_unread = mysqli_query($con, $update_unread);
echo "
<center><br />
<hr>
<h2>$msg_subject</h2><br/>
<p><b>Message:</b>$msg_topic</p><br />
<p><b>My reply:</b>$reply_content</p><br/>
<form action='' method='post'>
<textarea cols='60' rows='10' name='reply'></textarea><br /><br />
<input type='submit' name='msg_reply' value='Reply to this' />
</form>
</center>
";
}
if(isset($_POST['msg_reply'])){
$user_reply = $_POST['reply'];
if($reply_content!='no_reply'){
echo "<h2 align='center'>This message was already replied!</h2>";
exit();
} else {
$update_msg = "update messages set reply='$user_reply' where msg_id='$get_id'";
$run_update = mysqli_query($con, $update_msg);
echo "<h2 align='center'>Message was replied!</h2>";
}
}
}
?>
Bellow is the all code from my_messages.php. I decided to put it here all the code to avoid any questions regarding missing code information. Maybe will help to get the error.
The problem is at the end of the code when i try to click on my inbox and the messages are not displayed when i click on the sender subject. The form is not shown with the echo function.

var_dump( $row_message)
after fetching from database to see what's in it.
Please consider changing this line
$row_message = mysqli_fetch_array($run_message);
To this
$row_message = mysqli_fetch_assoc($run_message);
mysqli_fetch_array does not return associative array as you want to access further in your code.
Please Make sure you are passing msg_id in query string like someurl?msg_id=1, else you won't see anything inside
if(isset($_GET['msg_id'])){
/* get msg_id details from db and show */
}
this is because here we are checking if msg_id is set then show content. ;)

i have declared a session_start() function in the start of both the pages but still the variable is not passing on to the session variable please help
this is where i have included my login.php
<?php
include("template/header.php");
include("template/content.php");
include("template/footer.php");
include("login.php");
?>
this my login.php file where i have passed $email variable to SESSION
<?php
session_start();
include("includes/connection.php");
if(isset($_POST['login'])){
$email= mysqli_real_escape_string($con,$_POST['email']);
$pass= mysqli_real_escape_string($con,$_POST['pass']);
$select_user = "select * from users where user_email= '$email' AND
user_pass='$pass' AND status='verified'";
$query = mysqli_query($con,$select_user);
$check_user= mysqli_num_rows($query);
if($check_user===1){
$_SESSION['usermail']=$email;
echo "<script>window.open('home.php','_self')</script>";
} else {
echo "<script>alert('incorrect details try again')</script>";
}
}
?>
and this is where i have tried to access the session variable but it says undefined:usermail but i dont understand i am giving the session_start() at the beginning and have checked that $email is successfully getting its value from the database then why this is not working
<?php
session_start();

This is my current php and html code, I must of made a small error because I everytime I go to view it the only thing that shows on my screen is the jumbotron at the top with the test "card" inside it, please help me! I'm sure its just a small error that I cant find out the answer to.
Im assuming its the php code, if anyone can help that would be great.
Assuming that your query is actually retrieving the cards, the display isn't fetching the image from the returned result...
while($row = $result3->fetch_assoc()) {
?>
<div class="col-sm-4">
<div class="card">
<div class="card-img-top">
<img alt="" src="pics/<?php echo $img; ?>">
</div>
</div>
</div>
</div>
<?php
}
Using $img for the image isn't using the data from $row.
You should have something like...
echo $row['image'];
I'm also unsure if there is an extra </div> in the loop, you may need to move the last </div> outside the loop, but check this with the generated source.
Place the session_start() at the first line of page, i.e.:
session_start();
include ("db.php");
session_start(); must be started before any other line or operation.
<div class="jumbotron">
<div class="container text-center">

$sql3 = "SELECT * FROM cards WHERE user = '$user'";
$result3 = $conn->query($sql3);

I can get the form to run but cant get the information to change in the database or echo to the screen.
Thank you in advance.
if(array_key_exists('_submit_check', $_POST))
{
$email = $_POST['email'];
$city = $_POST['city'];
$sql = "UPDATE members SET city = '$city' WHERE email = '$q'";
if($mysqli->query($sql) === TRUE)
{
echo 'Record updated successfully<br />';
}
else
{
echo $sql.'<br />' . $mysqli->error;
}
$mysqli->close();
}
There is no element called '_submit_check' in your form. I guess you forgot the name attribute of your submit-button.
Your script is very vulnerable to SQL-Injection. You really should not simply throw the userinput into your query. You can use mysqli_real_escape_string() or Prepared Statements to protect your application.
To improve the readability of your code you could change the structure a little. In your admin1.php you should do the business logic before outputting any html. So you would first check if the form has been sent, then you do the database operation. The result of the check or the success/error-message of the database operation can be written into a variable until you output the content of your site.
This way everybody who starts reading the code immediately knows 'alright, this script is the target of some form and accesses the database for some write-operation'.
I wonder why the 2nd output $devNO gives me bool(false) which is empty. i have no idea about it. Am I wrong at the mysql_query() part?
$developer = $_POST['dev'];
$platform = $_POST['plat'];
$genre = $_POST['gen'];
var_dump($developer);
echo "<br>";
$devNO = mysql_query("SELECT No FROM developer WHERE Developer = $developer");
$platNO = mysql_query("SELECT No FROM platform WHERE Platform = $platform");
$genNO = mysql_query("SELECT No FROM genre WHERE Genre = $genre");
var_dump($devNO);
Here's my output:

The full output will be like this after i search from dropdown:
The method mysql_query() , if successful, returns a resultset, which has to be made an array even if only a single value is being returned from the query.
Ideally there should be a for-each iteration on this array to get result, however if you're sure you'll get at least one value, the first row with desired index('No' in your case).
$dataset= mysql_query("SELECT No FROM developer WHERE Developer = '$developer'");
$row = mysql_fetch_assoc($dataset);
$devNO = $row['No'];
Also note the quote I've used for varchar. It was correctly pointed in the other answer. Try Now.
If $developer is a string use quotes. You need to first fetch results from result set and than use it in code:
<?php
$devNOResult = mysql_query("SELECT No FROM developer WHERE Developer = '$developer'");
$platNOResult = mysql_query("SELECT No FROM platform WHERE Platform = '$platform'");
$genNOResult = mysql_query("SELECT No FROM genre WHERE Genre = '$genre'");
$devNO = mysql_fetch_row($devNOResult);
$sql = sprintf("SELECT Title, Release_Year, Language, Price FROM games WHERE Developer_NO = $devNO");
$result = mysql_query($sql);
$game_title = 'Title';
$game_year = 'Release_Year';
$game_lan = 'Language';
$game_price = 'Price';
?>
<div id="gamelist">
<?php
if(!$result) {
die(mysql_error());
}
while($row = mysql_fetch_array($result)) {
?>
The thing I'm asking for is how the users can visit other users profile.
The past week I have been scripting a social network I'm doing, and I'm kind of stuck right now.
I don't know where to start and read or anything.
So I'm asking you guys to kindly help me =)
Im thinking of the url to be like user.php?id=123 looking and get user you are visiting to show up instead of "you" wich is at user.php!
Live demo: http://social.swipper.org
EDIT #2:
Here's the current code i got inside user.php :
<?php
session_start();
if($_SESSION['username']) {
include "config.php";
$username = $_SESSION['username'];
$fetcher = mysql_query("SELECT * FROM userinfo WHERE username='$username'");
while ($data = mysql_fetch_assoc($fetcher)){
$firstname = $data['firstname'];
$lastname = $data['lastname'];
$gender = $data['gender'];
}
// get user's profile image
if (file_exists("users/$username/profile.jpg")) {
$userPhoto = "<img class='pic' src='users/$username/profile.jpg' width='90%' height='30%' />";
}
elseif (!file_exists("users/$username/profile.jpg")) {
$userPhoto = "<img class='pic' src='http://www.uavmedia.com/portal/images/no-user.jpg' width='90%' height='30%' />";
}
// the user's profile image is fetched
// henter profil text
$file = "users/$username/bio.txt";
$contents = file($file);
$profile_text = implode($contents);
// ferdig å hente profil text, vil nå echo ut profil siden.
// henter profil stilsett
$file2 = "users/$username/style.css";
$contents2 = file($file2);
$profile_style = implode($contents2);
// ferdig å hente profil stilsett.

";
}
else {
die("You need to login first or register. You can register/login <a href='index.php'>here</a>!");
}
?>
and when the url is like: user.php?id=3 i want to get the user with userid 3 to show up, and get user #3's information instead of the "user" who wants to visit other people.
Are you listing all the users some where? if you are the href needs to be something like
<?php
$sql = mysql_query("SLECET * FROM userinfo");
while ($row = mysql_fetch_assoc($sql)){
echo "<a href='users.php?id=" . $row['id'] . "'>"
}
then in users.php
<?php
if(isset($_REQUEST['id'])) {
if(is_numeric($_REQUEST['id'])){
$uid = $_REQUEST['id'];
$sql = mysql_query("SELECT * FROM userinfo WHERE id='" . $uid . "' LIMIT 1");
}
} else {
$sql = mysql_query("SELECT * FROM userinfo WHERE username='" . $_SESSION['username'] . "' LIMIT 1");
}
then later your html can use that with a fetch_assoc($sql)
<table>
<tr>
<td><?php echo $row['username'] ?>'s Profile</td>
</tr>
</table>
simple example. but i think you get the picture, message me on FB for more on this Stian
This should be your answer:
if (isset($_GET['username']){
$username = mysql_escape_string($_GET['username']);
}else{
$username = $_SESSION['username'];
}
$fetcher = mysql_query("SELECT * FROM userinfo WHERE username='$username'");
if (mysql_num_rows() == 0){
$username = '';
echo 'Username not found'; die();
}
Make your query like
$userID = $_GET['id'];
$fetcher = mysql_query("SELECT * FROM userinfo WHERE userID='$userID'");
and you can accordingly show data for any user with the valid user ID as given in url.
if profile can be viewed without login too then there is no need of session and if its compulsory only check if isset or not. if you are passing username in url as
user.php?user=test1
then your query will be like
$username = $_GET['user'];
$fetcher = mysql_query("SELECT * FROM userinfo WHERE username='$username'");
Hope now its more clear to u.
