Use php and sql to make an action url per item id - php

I am trying to make page in php/html that will display a "product's details." I have it displaying the icon and the link to the "details page," but it will not display ONLY one item on the "details page." Currently, the product's page (where the icon and the link are) will link to the "details page" just fine. However, when the page loads it loads every item in the sql database that has an 'ID.' I expected it to only take the item's id and display the page related to that item, however I received a cluster of them all... The code I have is what follows. I am currently trying to learn PHP so please if I make an error, a really bad one like something that isn't efficient. Please post the more efficient way of doing it. I am learning it the way I was taught at school.

Data duplicated in table filled with PHP

i am completely new to this world and i am trying to get more confident with PHP and MYSQL, so i am playing with a small web application just to fetch and retrieve data with MYSql and PHP.
I created a table in HTML and my goal is to retrieve this data from a mysql table with PHP
The problem is that the data are displayed twice... Can you help me understand where is error ?
Below the code :
<?php
session_start();
include_once("database.php");
$db = $conn;
$query = " SELECT categoria FROM categoria_prodotto";
$result = $db->query($query);
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<link rel="stylesheet" href="styles.css">
<title>test</title>
</head>
<body>
<section id="main-page">
<div class="link">
<span> Create a new purchase table </span>
</div>
<table>
<tr>
<td> category </td>
<td> product </td>
</tr>
<?php while ($row = mysqli_fetch_array($result)) :
foreach ($row as $temp) {
$query1 = "SELECT `nome` FROM `supermarket`.`lista_prodotto` WHERE `categoria_prodotto` = '$temp' ORDER BY `categoria_prodotto` DESC";
$result1 = $db->query($query1);
?>
<tr>
<td><?php echo $row[0]; ?> </td>
<td>
<?php while ($row1 = mysqli_fetch_array($result1)) :
echo $row1[0]; ?>
<?php endwhile;
}
endwhile; ?>
</td>
</tr>
</table>
<div class="link">
<span> Store a new product </span>
</div>
</section>
</body>
</html>
////
And here the result in browser with two row with same data duplicated each time
[here][1]
Thank you in advance for helping me to troubleshoot my problem :)

You have some unnecessary loops, also if you use the object oriented version of the MySQLI API its a lot easier to read. I also change the query to use a Prepared parameterised query that you bind data to before the executing the query, much safer and protects you against SQL Injection
<?php
session_start();
include_once("database.php");
$db= $conn;
$query = "SELECT categoria FROM categoria_prodotto";
$result = $db->query($query);
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<link rel="stylesheet" href="styles.css">
<title>test</title>
</head>
<body>
<section id="main-page">
<div class="link">
<span> Create a new purchase table </span>
</div>
<table>
<tr>
<td> category </td>
<td> product </td>
</tr>
<?php
while($categoria_prodotto = $result->fetch_assoc()):
$query1 = "SELECT `nome`
FROM `supermarket`.`lista_prodotto`
WHERE `categoria_prodotto` = ?
ORDER BY `categoria_prodotto` DESC";
$stmt1 = $db->prepare($query1);
$stmt1->bind_param('s', $categoria_prodotto['categoria']);
$stmt->execute();
$result1= $stmt->get_result();
$supermarket = $result1->fetch_assoc();
?>
<tr>
<td><?php echo $categoria_prodotto['categoria']; ?></td>
<td><?php echo $supermarket['nome']; ?></td>
?>
<?php
endwhile;
?>
</td>
</tr>

PHP undefined variable when I try to extract data from database

So I got these issues when I tried to extract data from the database. My DB connection is working fine. It is showing "Database connection established" and inside my index.php I wrote a for each loop to get the data and inside my HTML code, I display it inside the table. I got these errors:
Notice: Undefined variable: jokes in C:\xampp\htdocs\comp1321_database\jokes\jokes.html.php on line 16
Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\comp1321_database\jokes\jokes.html.php on line 16
Here is the HTML and php code to display the data:
<?php include_once 'admin/includes/helpers.inc.php';?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>List of Jokes</title>
</head>
<body>
<p>Add your own joke</p>
<p>Here are all the jokes in the database</p>
<!-- into a table -->
<table border="1">
<?php foreach ($jokes as $joke): ?>
<!-- <form action="?deletejoke" method="post"> -->
<tr>
<td><?php html($joke['joketext']);?></td>
<td><?php $display_date = date("D d M Y", strtotime($joke['jokedate']));
html($display_date); ?>
</td>
<td><img height="100px" src="images/<?php html($joke['image']);?>"
/></td>
<td><input type="hidden" name="id" value="<?php echo $joke['id'];
?>">
<input type="submit" value="Delete"></td>
</tr>
<!-- </form> -->
<?php endforeach; ?>
</table>
<?php include 'admin/includes/footer.inc.html.php';?>
</body>
</html>
and here is the index.php:
<?php
// selection block
include 'admin/includes/db.inc.php';
//
try
{
$sql = 'SELECT * FROM joke';
$result = $pdo->query($sql);
} catch (PDOException $e) {
$error = 'Error fetching jokes' . $e->getMessage();
include 'error.html.php';
exit();
}
foreach ($result as $row) {
$jokes[] = array(
'joketext'=> $row ['joketext'],
'jokedate'=> $row['joketext'],
'image'=> $row['image']
);
}
include 'jokes.html.php';
?>
Many thanks.

Initialize your jokes variable before you try to use it, ie:
$jokes = [];
try
{
$sql = 'SELECT * FROM joke';
$result = $pdo->query($sql);
} catch (PDOException $e) {
$error = 'Error fetching jokes' . $e->getMessage();
include 'error.html.php';
exit();
}
foreach ($result as $row) {
$jokes[] = array(
'joketext'=> $row ['joketext'],
'jokedate'=> $row['joketext'],
'image'=> $row['image']
);
}

You need define $jokes on your php file, you can do it on header of file.
<?php include_once 'admin/includes/helpers.inc.php';?>
<?php
$jokes = someGetJokesFunction(); // write function to get data from database
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>List of Jokes</title>
</head>
<body>
<p>Add your own joke</p>
<p>Here are all the jokes in the database</p>
<!-- into a table -->
<table border="1">
<?php foreach ($jokes as $joke): ?>
<!-- <form action="?deletejoke" method="post"> -->
<tr>
<td><?php html($joke['joketext']);?></td>
<td><?php $display_date = date("D d M Y", strtotime($joke['jokedate']));
html($display_date); ?>
</td>
<td><img height="100px" src="images/<?php html($joke['image']);?>"
/></td>
<td><input type="hidden" name="id" value="<?php echo $joke['id'];
?>">
<input type="submit" value="Delete"></td>
</tr>
<!-- </form> -->
<?php endforeach; ?>
</table>
<?php include 'admin/includes/footer.inc.html.php';?>
</body>
</html>

How to pass php variable to a new page for deleting a row from the database?

On the list.php page, I am passing a variable using hidden input method in form.
This form redirects to listd.php where the variable is used to run an SQL query to delete a particular row from the database where the variable==name.
If I print the variable on listd.php before processing SQL query then it is visible but during when query is processed it gives unidentified index error.
The code in listd.php works if I take input from the user on the same page.
list.php

It's really not necessary to use two forms to do this, unless this is a very dangerous action. this is also the source of your problem. $k is not preserved on the second postback. Requests are stateless. When you submit the second form, the listd.php script runs again from the start, and the values assigned to variables the last time it ran. This is the normal behaviour of HTTP requests in general.
A single-form version might look like this:
list.php
<?php
//this needs to be before anything else otherwise the redirect might fail due to headers already sent.
session_start();
if(isset($_SESSION['username'])) //corrected to use isset(). Only one test for this is needed.
{
echo "<h2>Welcome ".$_SESSION['username']."!</h2>";
echo "<h3><a href='logout.php'>Logout</a></h3>";
}
else
{
header('location:index.php');
die(); //script needs to die because webcrawlers/bots will ignore the redirect header, and view the rest of the page anyway, without permission. Using die() means the rest of the page never gets output.
}

You do not need listd.php at all.
P.S. A separate hint: I see you are copying the same HTML <head> etc material into every page script. This is not necessary. You can create two files e.g. header.php and footer.php. In header.php you can put the opening <html> and <head> tags right down to <body> and any other enclosing tags necessary for the consistent layout of all your pages. Then in footer.php you can put the equivalent closing tags. And then in all the other pages of your site you can simply write <?php require_once("header.php"); ?> as the first line and <?php require_once("footer.php"); ?> as the last line. Then any changes you need to make to the headers (e.g. new CSS files or something) are automatically applied to all the pages without tedious copy/paste actions. Although I suggested that you remove your second script here, you can do this for any other pages in your site. It's also a good general principle of code re-use which you can apply to all kinds of situations in your future code.
P.P.S. I'd also consider using an up-to-date doctype. The HTML5 doctype declaration is simply <!DOCTYPE html>. This will likely result in more consistent behaviour of the HTML and CSS in your page, and future-proofs your application against deprecation of older doctypes which are no longer in current use.

Display icon on profile if user has been defined as $admin

I am working on a little forum, and I want it to be easy to identify a staff member.
A the moment, a user is defined as an $admin in the config file:
<?php
/******************************************************
------------------Required Configuration---------------
Please edit the following variables so the forum can
work correctly.
******************************************************/
//We log to the DataBase
mysql_connect('127.0.0.1', 'root', '');
mysql_select_db('forum_database');
//Forum Staff
$admin='The_Darthonian'; // For admin forum features
/******************************************************
-----------------Optional Configuration----------------
******************************************************/
//Forum Home Page
$url_home = 'index.php';
//Design Name
$design = 'default';
/******************************************************
----------------------Initialization-------------------
******************************************************/
include('init.php');
?>
I have an icon at the path of default/images/role_moderator.gif that I want to appear on a profile if a user is defined as an admin
I further have a userid variable. For example, the first account would be 1, then the second 2 and so on which are unique. Below is the profile code:
<?php
//This page display the profile of an user

How can I make it so that if a user is defined as an $admin in the config, they have the icon appear on their profile?

Error while implementing implode ,explode array with php

I have this code, that picks article content from my word press db then outputs it onto a table, using a loop. once a user select the articles they like they submit the selection to my next page call it displaypage to display the selected articles.
the selection page code looks like this.
<?php /*
Template Name: News Selector Template
*/
//Pull the data
$posts = $wpdb->get_results
("
SELECT
p1.*,
wm2.meta_value
FROM
mp_posts p1
LEFT JOIN
mp_postmeta wm1
ON (
wm1.post_id = p1.id
AND wm1.meta_value IS NOT NULL
AND wm1.meta_key = '_thumbnail_id'
)
LEFT JOIN
mp_postmeta wm2
ON (
wm1.meta_value = wm2.post_id
AND wm2.meta_key = '_wp_attached_file'
AND wm2.meta_value IS NOT NULL
)
WHERE
p1.post_status='publish'
AND p1.post_type='post'
ORDER BY
p1.post_date DESC LIMIT 0,30
");
?>

Iv used implode to collect the array variables of all selected articles via a check box option.
on my display page i wrote this simple code to see the output of the array.
<?php /*
Template Name: Newsletter Template
*/
$posts = explode(",", $_POST['metas']);
?>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
</head>
<body>
<?php echo $posts[0]->guid ?>
<?php echo $posts[0]->meta_value ?>
<?php echo $posts[0]->post_title ?>
<?php echo $posts[0]->post_excerpt ?>
</body>
</html>
Now when i submit the selected articles from the first page i'm supposed to be able to access the various array elements in my display page, but that's not the case. i get the
ERROR
Warning: implode(): Invalid arguments passed in
/home/sampled/public_html/brands/sample/wp-content/themes/newsample/page-newsselector.php
on line 164
i don't know where i went wrong with my implementation.
HELP PLEASE
