- Firstly, display your code in code tags, identified by the "<>" icon on the top

- Second, make you have all your logic ABOVE the HTML.

- Trim your code to the stuff that is relevant

- Ask a question and tell us what is not working.

- It would be wise to indent your code :/ this is so hard to read.

 

Seriously, you arent even asking a question.

I dont see your code in code blocks. So thats one thing you havent done. None of the things I said will actually solve anything. But it MAY help us understand your problem and give guidance (we wont solve your problem for you. Well sometimes we will.).

 

REGARDLESS, I am completely missing your problem. What is the issue?!

HERE, this is what we need. Not a file, but code in code blocks:


<?php
define('upath','mismatch/images1/');
define('msize',1024*50);
if(isset($_SESSION['user_id']))
{
	$id1=$_SESSION['user_id'];
	if(isset($_POST['submit']))
		{
			$dbc=mysqli_connect('localhost','root','','mismatch')
				or die('Error connceting database');
			if((!empty($_POST['fname']))&&(!empty($_POST['lname']))&&(!empty($_POST['bday']))&&
				(!empty($_POST['sex']))&&(!empty($_POST['nation'])))
			{
				$fname=$_POST['fname'];	
				$lname=$_POST['lname'];
				$bday=$_POST['bday'];
				$sex=$_POST['sex'];
				$nation=$_POST['nation'];
				if(!empty($_FILES['screenshot']['name']))
				{
				$screenshot=$_FILES['screenshot']['name'];
				if(($_FILES['screenshot']['size']>0)&&($_FILES['screenshot']['size']<msize))
					{
					$target=upath.$screesnhot;
					if(move_uploaded_file($_FILES['screenshot']['tmp_name'],$target))
						{
						$query="SELECT * FROM mismatch_user WHERE user_id=$id1";
						$result=mysqli_query($dbc,$query)
							or die('Error getting data');
						if(mysqli_num_rows($result)==1)
							{
						$query1="UPDATE mismatch_user SET firstname='$fname', lastname='$lname', birthday='$bday',".
							"gender='$sex', country='$nation', picture='$screenshot' WHERE user_id='$id1'";

								$result1=mysqli_query($dbc,$query1)
								or die('Error quering database');
								echo'<br/><b>Profile Edited successfully</b>';
							}
							
					
						}
					else
						{
							echo'<br/><b/>File cannot be uploaded';
						}
					}
				else
					{
					echo'<br/><b/>Check size of Image.';
					}
				}
				else
					{
					$query2="UPDATE mismatch_user SET firstname='$fname', lastname='$lname', birthday='$bday',".
							"gender='$sex', country='$nation' WHERE user_id='$id1'";
					$result2=mysqli_query($dbc,$query2)
					or die('Error quering database');
					echo'<br/><b>Profile Edited successfully</b>';
					}
			}				
		else
		{
			echo'<br/><b/>Please Enter all the information.';
		}
	}
}
?>

Okay so it doesnt update even tho you would expect it to. A good step at debugging would be to add echos or var_dumps to see which IFs are triggering and which arent. Its a really basic process, but you can try something like:

if(isset($_SESSION['user_id']))
{
  echo 'User session is set<br>';
	$id1=$_SESSION['user_id'];
	if(isset($_POST['submit']))
		{
 echo 'Form is submitted<br>';
			$dbc=mysqli_connect('localhost','root','','mismatch')
(...)

Do that on several key IF statements, to see where your code is going. The issue doesnt have to be lay in the PHP. Try it out and see how far your script actually goes.

If nothing is echoed then that means your SESSION is not set. Try doing a var_dump on $_SESSION on the top of the page, like so:


<?php
define('upath','mismatch/images1/');
define('msize',1024*50);

var_dump($_SESSION);
  die(); // kill the rest of the page
if(isset($_SESSION['user_id']))
{

What does that echo?

That is because you are not creating a session, check out the function session_start() and how you can use it.

 

Also, I PRESUME you are checking for a session because you have some sort of login functionality. Since you built a login system, I presume you also know how to handle sessions.

yes i have built a login system that redirects to edit page means current page

 

but when we edit our information no data is updated in database

and i have created a session using session_start();

so i didnt use it again in edit page

because session_id is set now.

 

i am attaching login script too please have a look on it too.

loginx.php

The session on a page will only exist if you call session_start() on that page, and as the var_dump shows the issue you are facing has nothing to do with your update. The issue lies in the fact that you dont have a session active on that page. Make sure you have a session and go from there.

but when i write if(!isset($_SESSION['user_id'])) at place of if(isset($_SESSION['user_id']))

 

i got feedback 'profile updated successfully'.

but when i saw my database nothing was updated.

ofc this works, but thats exactly what you DONT want.

 

Please put your code in code blocks.

 

What you need to think about is: how can I solve this issue on my own without making someone else do it for me. You have two error messages, so copy the first and google it.

The first link is a stackoverflow question. The answer is on that page. Do some research and dont expect us to do it for you.
