How to fix the error?
Jump to PostIs line 76 of the input_image.php actually a line 13 in the above snippet? If yes, obviously
$_SESSION['adm_banner.jpg']does not exist. Where is it supposed to be set?
Jump to PostYes, but where is the
$_SESSION['adm_banner.jpg']being set? If you want to echo it you have to set it first.
Jump to PostI agree with Broj1 .
Jump to PostOK, again. Where is the
$_SESSION['adm_banner.jpg']getting set?On line 7 in your first post you assign a value from the database to the
$bannervariable:$banner = $data['image_bn'];Then on line 13 you try to echo the
$_SESSION[$banner]variable:

yes, line 13 = line 76.
It is set in here:
input_image.php
$banner = $data['image_bn'];
Yes, but where is the $_SESSION['adm_banner.jpg'] being set? If you want to echo it you have to set it first.
I agree with Broj1 .
<?php echo $_SESSION[$banner]; ?>
$banner = $data['image_bn'];
$banner = 'adm_banner.jpg'; // it gets from $data['image
_bn'];
OK, again. Where is the $_SESSION['adm_banner.jpg'] getting set?
On line 7 in your first post you assign a value from the database to the $banner variable:
$banner = $data['image_bn'];
Then on line 13 you try to echo the $_SESSION[$banner] variable:
echo $_SESSION[$banner];
From the error message it seems that the value of the $banner variable is adm_banner.jpg. So you are essentially trying to echo the $_SESSION['adm_banner.jpg'] variable. The question is: has the $_SESSION['adm_banner.jpg'] been set at all anywhere in the code? It seem not. I guess you have an error in your logic.
I already place this code on top of:
input_image.php
<?php
session_start();
?>
Still does not answer my question: has the $_SESSION['adm_banner.jpg'] been set at all anywhere in the code? Is there a line saying:
$_SESSION['adm_banner.jpg'] = 'something';
or maybe:
$_SESSION[$banner] = 'something';
so you can then echo it. I doubt it is. You probably have an error in your logic. Try to describe what you want to achieve.
I only except when you print
<?php echo $_SESSION[$banner]; ?>
It prints something like: adm_banner.jpg
instead of: Notice: Undefined index: adm_banner.jpg in C:\xampp\htdocs\portal\administrator2\admin\input_image.php on line 76
Maybe it should be:
<?php echo $_SESSION['banner']; ?>
but I can't tell without seeing the code where you set the $_SESSION value.
Well, this is the whole session code part:
<?php
include('includes/koneksi.php');
session_start();
?>
<?php
$result = mysql_query("SELECT * FROM image_upload ORDER BY image_id ASC");
$data = mysql_fetch_array($result);
$banner = $data['image_bn'];
?>
<p><img src="../../images/<?php $banner; ?>"></p>
<?php echo $_SESSION[$banner]; ?>
I still do not understand what's wrong.
You can not echo $_SESSION[$banner] if $_SESSION[$banner] has not been set before.
I already try redefining the value:
$_SESSION[$banner] = $data['image_bn'];
<?php echo $_SESSION[$banner]; ?>
