I'm trying to sort a PHP generated form by price. I get an error message 'Notice: Undefined index: PriceDesc/Asc'. I understand the error message but can't find any relevant info through searching so thought I'd ask. I'm new to PHP and so far this is the code I have:

For the record, I'm using PhpMyAdmin for my backend d/b and the initial tabled data works fine.
Replace
$data = mysql_query("SELECT * FROM products");
IF ($_GET['PriceAsc']){
$orderby =" ORDER BY price ASC";
}
IF ($_GET['PriceDesc']){
$orderby =" ORDER BY price DESC";
}
with
if ( !empty($_GET['sort']) && $_GET['sort'] == 'PriceAsc' ) {
$orderby=" ORDER BY price ASC";
}
if ( !empty($_GET['sort']) && $_GET['sort'] == 'PriceDesc' ) {
$orderby=" ORDER BY price DESC";
}
$data = mysql_query("SELECT * FROM products".$orderby);
Note the changes, you need to use empty() to check if form submitted and check the value of it. And do the query once Order by appended to SQL.
Yes append the $sort to the $data as above
and you'll need those query strings to be coming in correctly with the url
http://www/mypage.php?PriceAsc=true
and you'll need to compare it correctly
if ($_GET['PriceAsc']=='true'){
You never attached the $orderby variable to the query. Try this:
$data1 ="SELECT * FROM products";
IF ($_GET['PriceAsc']){
$data1 .=" ORDER BY price ASC";
}
IF ($_GET['PriceDesc']){
$data1 .=" ORDER BY price DESC";
$data = mysql_query($data1);
The .= appends the string to the end of $data
And reason you getting the undefined index error is because theres no PriceAsc available! Youre trying to $_GET something that doesnt exist.
What you need to do is :
IF ($_GET['sort'] == 'Price: Highest First'){
$data1 .=" ORDER BY price ASC";
} else {
$data1 .=" ORDER BY price DESC";
}

Recently I am writing a products catalog for my company. I use the dropdown list to provide a filter to a grid views product list that has pagination. The filter is work fine if products not more than 1 page. When more then one page of search result, the browser will show all products same as no filter applied. Below is my code of the index.php. Please help because I already stuck in here for a week. Thank in advance.

Your logic seems OK but your problem is when you navigate trough pages you make a new call of the document, which doesn't include variables like filters but the current page ($_GET['page']).
Either you send filters as variables trough URL as well, which isn't the cleanest way to do table pagination.
Or you gather results in a javascript array, and then on click on a pagination button display the previous/next rows. By doing this you also avoid refreshing the whole document every time, which isn't necessary.
In this code I'm trying to create as many modal boxes as the rows of my query result. This works! Then I want to fill these modal boxes with as many checkboxes as the number $row['seats_no'] from database. Here we have a problem..in every modal box it creates the same amount of checkboxes as the first one. What I mean is that the $row['seats_no'] has the number from the first row in every row.

here are the results i get from executing my query at phpMyAdmin
Here are the buttons I create to open the modals
And here is the modal from the last button i clicked that in the database shows it should be 60 checkboxes but it shows 180
Κατερίνα,
Try to change the while ($row = mysqli_fetch_array($r)) {...} with a foreach loop,
like as foreach( mysqli_fetch_array($r) as $row ) {....}
Just a thought.
Also, you close one bracket too soon, remove one before the first mysqli_free_result($r1) and close it after the closing html tag </html> at the end of the file.
Also, as #tadman said, do some research and use parameterized queries. Your code it's very prone to MySQL Injections and you will face several problems. As far as i can see that page has to do with payments, or pre-payment.
Anyways, i hope i helped you.
Καλή επιτυχία ;)
Forewarning: I'm sure my code is clunky and inefficient, please feel free to call me out on it. I'm fairly new at this.
I'm attempting to order my query results by a column, indicated as a result of a select input. The select input exists on feed.php which features include: 'feedphp2.php.
The select input auto-submits onchange with action="feedSort.php". feedSort.php takes the submitted value and redirects to feed.php?sort=submittedValue. Then the included feedphp2.php within feed.php takes the $_GET['sort'] value and pulls a query sorted by that column.

Columns within my table exist for both user and dateAdded and sort perfectly when explicitly provided within the query ie: SELECT * FROM meals
ORDER BY user. While provided through a PHP variable however:
Where $sortBy = user returns the exact same sort order as $sortBy = dateAdded.
I appreciate any help you might provide.
you using $_POST method to pass the value and using $_GET method to retrieve it . and change the $sortby without quotes. edit these lines in your feedphp2.php
<?php
include 'MysqlConnect.php';
mysqli_select_db($conn,$dbname);
if (isset($_POST['sort'])) {
$sortBy = $_POST['sort'];
echo $sortBy;
$resultQuery = "SELECT * FROM meals
ORDER BY $sortBy";
} else {
or use $_REQUEST[],Method which will retrieve both get and post method
<?php
include 'MysqlConnect.php';
mysqli_select_db($conn,$dbname);
if (isset($_REQUEST['sort'])) {//request method
$sortBy = $_REQUEST['sort'];//
echo $sortBy;
$resultQuery = "SELECT * FROM meals
ORDER BY $sortBy";
} else {
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);

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)) {
?>
I have a fully working piece of PHP, HTML code but when I place it into my website that is styled using jQuery Mobile the submit button will not display the query. Does anybody know how to fix this or even why it is happening

Please keep in mind that this script is fully implemented on a plain HTML site. I am only having issues with the jQuery mobile library.
Thank You in advance
Let me give you an answer, I found everything going through your code.
Inside a index.php:
data-ajax="false" should be added as a form attribute, it prevents jQuery Mobile from using ajax to submit data.
Incorrect jQuery Mobile css was initialized in a HEAD
table tag was not closed
But, through and trough this is well built page.
