I asked this question before but did not get any actual answers. I created a website for my wife's jewelry. She wants a product page for each style she makes (bracelets, necklaces, etc.).
I created the database with a category section that has all the different categories she makes. The only problem I have is I cannot get the information to show up on the product page. I get errors such as
Notice: Undefined variable: item_number in C:\xampp\htdocs\pinkys_pearls\bracelets.php on line 83.
Here is my code for the page:
<?php
error_reporting(E_ALL);
ini_set('display_startup_errors', 1);
ini_set('display_errors', 1);
?>
<?php
// Connect to the MySQL database
include_once("storescripts/connect_to_mysql.php");
$con = mysqli_connect("$db_host","$db_username","$db_pass","$db_name");
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_errno());
exit();
//Initializing variable
$item_number = "item_number";
$description = "description";
$category = "category";
$price = "price";
$qty = "qty";
$sql = "SELECT category FROM products WHERE category='Bracelets';";
$result = mysqli_query($con, $sql);
$resultCheck = mysqli_num_rows($result);
if ($resultCheck > 0) {
// get all the product details
while($row = mysqli_fetch_assoc($result)); {
echo $item_number = $row["item_number"];
$price = $row["price"];
$desc = $row["description"];
$category = $row["category"];
}
}
else {
echo "Data to render this page is missing.";
exit();
}
}
?>

What can I do to fix this?
You are missing a closing curly bracket at a critical point -
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_errno());
exit();
// RIGHT HERE
//Initializing variable
$item_number = "item_number";
$description = "description";
$category = "category";
With out it, none of your variables are initialized, your SQL query is never run, etc.
Once you've fixed that, try again and if there are still related issues edit the question, otherwise start a new question for a new issue.

I was able to fetch and display the data but I am unable to download the file using dowload button.

How can I create my download button to actually download that particular file?
<a href="/path/to/image" download>
<img src="/path/to/image" />
</a>
If you want to download any file on clicking a button you must try this:
<a class="btn" href="<?= $your_path_to_file ?>" download>Download File</a>
Been working on a product page for my wife's jewelry site. I added php from a tutorial and tried to run the page. None of the images including the header showed up along with the footer. They show up on every other page. None of the information product showed up either. the page says connection opened and i receive no errors. The navigation shows up along with some of the css but that is all.
Here is my code I am using.
<?php
error_reporting(E_ALL);
ini_set('display_startup_errors', 1);
ini_set('display_errors', 1);
?>
<?php
if (isset($_GET['id'])) {
// Connect to the MySQL database
include_once("storescripts/connect_to_mysql.php");
$con =
mysqli_connect("$db_host","$db_username","$db_pass","$db_name");
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_errno());
exit();
} $id = preg_replace('#[^0-9]#i', '', $_GET['id']);
$sql = "SELECT * FROM products WHERE category='Bracelets';";
$result = mysqli_query($con, $sql);
$resultCheck = mysqli_num_rows($result);
if ($resultCheck > 0) {
// get all the product details
while($row = mysqli_fetch_assoc($result)); {
$item_number = $row["item_number"];
$price = $row["price"];
$desc = $row["description"];
$category = $row["category"];
}
} else {
echo "Data to render this page is missing.";
exit();
}

Please make sure your paths are right!
Try to change your links
<?php include_once("c:/xampp/htdocs/pinkys_pearls/templates/template_bracelets.php"); ?>
<?php include_once("c:/xampp/htdocs/pinkys_pearls/templates/template_navigation.php"); ?>
as
<?php include_once("localhost/pinkys_pearls/templates/template_bracelets.php"); ?>
<?php include_once("localhost/pinkys_pearls/templates/template_navigation.php"); ?>
and make sure with your image paths, if folder varies you cannot get load the images.
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.

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.
I am very new to using PHP.I would like to create a comment box for the user.
1. How do you save the comment in the database
2. How do you see if there are any posts
3. How do you display all posts to current page.
I am using Wampsever/MySQL Workbench. May I have help? Thank you!
<?php
require_once("db_connection.php");
require_once("needed_functions.php");
if (isset($_POST['submit']))
{
//Take Comment
$comment_id = $_POST["comment"];
if ($message == "" )
{
$query = "INSERT INTO comment (";
$query .= "comment";
$query .= ") VALUES (";
$query .= " '{$comment}'";
$query .= ")";
//connect &select
$mysqli = new mysqli("localhost", "user_id");
//query
$result = $mysqli->query("INSERT INTO Comment () VALUES();")
//close
$result->close();
}

When using database connections in PHP make sure you do the following
//connect &select
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
//query
$result = $mysqli->query("INSERT INTO tbl_name () VALUES();") // Add the update comment here
//close
$result->close();
Always remember to :
connect
select
query
close
you'll then need to get all of the comments for the page using the same process but with the select process rather than insert.
<?php
require_once("db_connection.php");
require_once("needed_functions.php");

I hope all of your questions are answered. If not then reply to me....
Error For some reason I'm not finding:
Your screenshot is exactly what I am looking
I have a page with a dropdown box at the top populated from the database, when I select an item from the dropdown it gives a list of results with a checkbox at the end of each line, I want to be able to select, using each checkbox, any number of results, and submit a value back into a field in the database for each result selected.
I sort of have this working, but it submits the value to every field in the database, rather than just the ones selected

No worries. Just put the code of insert query inside foreach() loop. Like this:
foreach($_POST['check_list'] as $item)
{
$sql="INSERT/UPDATE Query";
//for example
$sql = "INSERT INTO table_demo (field_1, TARGET_FIELD, field_2, field_3) VALUES (val_1, $item, val_2, val_3)";
$insert = mysqli_query($connection,$sql);
}
//next code of your choice
That is really Easy to give a go.
See this is same as you want.
In this link the first answer by Sean Valsh is your solution.
Giving the array as name of every checkbox will give you only chacked option's id in array while submitted.
