I need my carts page to be able to remember the total price of items, I have 3 items and they are all the same price (to make things simpler on my self). A user can submit the quantity using a form on another page. What I need the code to do remember the quantity for item 1, then when item 2 is submitted via the form it will add the quantity of the previous with the quantity submitted by the new item. So far iv gotten it to send the quantity through the form into the array, then it can be called whenever it's needed, but I can't figure out how I'm supposed to make it add the previous qty with the new one to give me a total price.
I don't think all the code is needed to help with this so I'll just post what I think is needed. If you want to see it all though just ask and I'll edit my post to include it.
My code:

As mentioned by #sudhansu, Session is the best option here, What you can do here is create a session's key-value pair per item.
for e.g. onsubmit a quantity for item_CNT you just set a session value with following keys in it.
$_SESSION[itemCNT][quantity] = 100;
$_SESSION[itemCNT][name] = 'name';
$_SESSION[itemCNT][id] = 71273928739;
you can increment CNT as an when user adds quantity for a particular item.
You can loop through the SESSION array whenever you need it. you can access this session from any page.
To save those cart value. You can do it in three ways.
Session
Cookie
Db
If you want to keep track on user's cart. you can create cart table. and put the value of quantity and item id inside the cart page. and if you need value for a specific session, just store it inside session. and if you want to store it inside user's browser. just store it in cookie.
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 have a database which contains 2 tables. In the second table there are numerous records and I'm trying to echo out the latest id (MAX id) to the page using PHP. There is something wrong with my code and I don't know what that is:
$sqlCount = "SELECT MAX(id) FROM records";
$sql = "SELECT id,preview,description FROM records";
$pn = (isset($_GET['pn'])) ? $_GET['pn'] : 1;
$res = upagination($con, $sql, $sqlCount, $pn, 6);
$list .="<table border=0>";
foreach ($res['rows'] as $row) {
$list .="<tr>";
$list .="<td>" . $row['id'] . "</td><td>" . $row['preview'] . "</td><td>" . $row['description'] . "</td>";
$list .="</tr>";
}
$list .="</table>";
$paginationCtrls = "";
if (isset($res['backLink'])) {
$paginationCtrls .= "Previous";
}
if (isset($res['numbers'])) {
foreach ($res['numbers'] as $number) {
if ($number === $res['current']) {
$paginationCtrls .= "$number";
}
(some deleted code to shorten this a little)

The last row I'm trying to echo out is the $list variable, but I get nothing. I have made a CSS on this file and define width, height, position, and float properties, but end up getting nothing from database.
I wish to set the title of my webpage to Ultan.me - Whatever the post title. I want it to display the post title. The posts are submitted to a MySQL database and the title row is called "title". Any help is appreciated with this small question.
Update:
Here is the page itself now but it doesn't display the title. Should I open the php document and connect to my database somewhere different to it's current locations?

Here's the method I use (for similar things, not just title):
<?
ob_start (); // Buffer output
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">
<head>
<title><!--TITLE--></title>
</head>
<body>
<?
$pageTitle = 'Title of Page'; // Call this in your pages' files to define the page title
?>
</body>
</html>
<?
$pageContents = ob_get_contents (); // Get all the page's HTML into a string
ob_end_clean (); // Wipe the buffer
// Replace <!--TITLE--> with $pageTitle variable contents, and print the HTML
echo str_replace ('<!--TITLE-->', $pageTitle, $pageContents);
?>
PHP usually works be executing any bits of code and printing all output directly to the browser. If you say "echo 'Some text here.';", that string will get sent the browser and is emptied from memory.
What output buffering does is say "Print all output to a buffer. Hold onto it. Don't send ANYTHING to the browser until I tell you to."
So what this does is it buffers all your pages' HTML into the buffer, then at the very end, after the tag, it uses ob_get_contents () to get the contents of the buffer (which is usually all your page's HTML source code which would have been sent the browser already) and puts that into a string.
ob_end_clean () empties the buffer and frees some memory. We don't need the source code anymore because we just stored it in $pageContents.
Then, lastly, I do a simple find & replace on your page's source code ($pageContents) for any instances of '' and replace them to whatever the $pageTitle variable was set to. Of course, it will then replace <title><!--TITLE--></title> with Your Page's Title. After that, I echo the $pageContents, just like the browser would have.
It effectively holds onto output so you can manipulate it before sending it to the browser.
Hopefully my comments are clear enough.
Look up ob_start () in the php manual ( http://php.net/ob_start ) if you want to know exactly how that works (and you should) :)
You parse the field from the database as usual.
Then let's say you put it in a variable called $title, you just
<html>
<head>
<title>Ultan.me - <?php echo htmlspecialchars($title);?></title>
</head>
EDIT:
I see your problem. You have to set $title BEFORE using it. That is, you should query the database before <title>...
header.php has the title tag set to <title>%TITLE%</title>; the "%" are important since hardly anyone types %TITLE% so u can use that for str_replace() later. then, you use output buffer like so
<?php
ob_start();
include("header.php");
$buffer=ob_get_contents();
ob_end_clean();
$buffer=str_replace("%TITLE%","NEW TITLE",$buffer);
echo $buffer;
?>
For more reference, click PHP - how to change title of the page AFTER including header.php?
What about using something like:
<?php
$page_title = "Your page tile";
include("navigation.php"); // if required
echo("<title>$page_title</title>");
?>
Move the data retrieval at the top of the script, and after that use:
<title>Ultan.me - <?php echo htmlspecialchars($title, ENT_QUOTES, 'UTF-8'); ?></title>
You need to set the value of $title before echoing it.
Also, you should really sanitize any data before using it in queries as this is a security risk
create a new page php and add this code:
<?php
function ch_title($title){
$output = ob_get_contents();
if ( ob_get_length() > 0) { ob_end_clean(); }
$patterns = array("/<title>(.*?)<\/title>/");
$replacements = array("<title>$title</title>");
$output = preg_replace($patterns, $replacements,$output);
echo $output;
}
?>
in <head> add code: <?php require 'page.php' ?> and on each page you call the function ch_title('my title');
The problem is that $title is being referenced on line 5 before it's being assigned on line 58. Rearranging your code isn't easy, because the data is both retrieved and output at the same time. Just to test, how does something like this work?
Because you're only retrieving one row, you don't need to use a while loop, but I left it with hopes that it'll make it easier for you to relate to your current code. All I've done is removed the actual output from your data retrieval, and added variables for category and category name which are then referred to as usual later on. Also, I haven't tested this. :)
It'll be tricky to rearrange your code to make this work, but I'll try :)
So, put this at the top of your code:
<?php require_once('mysql.php'); ?>
The top of the file should look like:
<?php require_once('mysql.php'); ?>
<html>
<head>
<meta name="keywords" content="Mac user Ultan Casey TheCompuGeeks UltanKC">
<title>Ultan.me - <?php echo htmlspecialchars($title); ?> </title>
Then, create a file called mysql.php in the same directory that the file which contains the code you quoted is in.
Put this is mysql.php:
<?php
mysql_connect ('localhost', 'root', 'root');
mysql_select_db ('ultankc');
if (!isset($_GET['id']) || !is_numeric($_GET['id'])) {
die("Invalid ID specified.");
}
$id = (int)$_GET['id'];
$sql = "SELECT * FROM php_blog WHERE id='$id' LIMIT 1";
$result = mysql_query($sql) or print ("Can't select entry from table php_blog.<br />" . $sql . "<br />" . mysql_error());
$res = mysql_fetch_assoc($result);
$date = date("l F d Y", $res['timestamp']);
$title = $res['title'];
$entry = $res['entry'];
$get_categories = mysql_query("SELECT * FROM php_blog_categories WHERE `category_id` = $res['category']");
$category = mysql_fetch_array($get_categories);
?>
Well, hope that helped :)
I know this is an old post but having read this I think this solution is much simpler (though technically it solves the problem with Javascript not PHP).
<html>
<head>
<title>Ultan.me - Unset</title>
<script type="text/javascript">
function setTitle( text ) {
document.title = text;
}
</script>
<!-- other head info -->
</head>
<?php
// Make the call to the DB to get the title text. See OP post for example
$title_text = "Ultan.me - DB Title";
// Use body onload to set the title of the page
print "<body onload=\"setTitle( '$title_text' )\" >";
// Rest of your code here
print "<p>Either use php to print stuff</p>";
?>
<p>or just drop in and out of php</p>
<?php
// close the html page
print "</body></html>";
?>
Simply add $title variable before require function
<?php
$title = "Your title goes here";
require("header.php");
?>
header.php
<title><?php echo $title; ?></title>
<?php echo APP_TITLE?> - <?php echo $page_title;?>
this should work fine for you
if you want to current script filename as your title tag
include the function in your project
function setTitle($requestUri)
{
$explodeRequestUri = explode("/", $requestUri);
$currentFileName = end($explodeRequestUri);
$withoutExt = preg_replace('/\\.[^.\\s]{3,4}$/', '', $currentFileName);
$explodeCurrentFileName = explode("-", $withoutExt);
foreach ($explodeCurrentFileName as $curFileValue)
{
$fileArrayName[] = ucfirst($curFileValue);
}
echo implode(" ", $fileArrayName);
}
and in your html include the function script
and replace your title tag with this
<title>Your Project Name -
<?php setTitle($_SERVER['REQUEST_URI']); ?>
</title>
it works on php7 and above but i dont have any idea about php 5.*
Hope it helps
