Ok, here's more information on AJAX for you http-equiv works so long as your page is quick at loading.

I want to write a tome about SPAM and its prevention, how do I start?

Make pages work without JavaScript first. no need for JavaScript HTML was able to do this before JavaScript was thought of. <meta http-equiv="refresh" content="3;url=https://www.mozilla.org"> Just be sensible in its use. So long as your page doesn't take too long to load, there should be little to n...

The simplest way to do this is to use the HTML lang tag, there is probably little SEO value in doing anything else, search engines use the lang tag in the document header. <!DOCTYPE html> <html lang="en"> It is possible to use directory strucure if you really want to, but, that can be a lot of work ...

Decide what data you need.

Decide how it is to be presented.

Design the database.

Design the web pages.

Decide on any interactions (adding, editing, deleting, sorting, viewing etc..)

Ok, long answer short (please don't take offence at the tone of my answer, I intend only to help you and text doesn't always convey tone very well): It's probably not a good idea to use $_SESSION to store that much data, if you are using it to return pages for verification - what happens to the sess...

You've answered your own question: it's not the data in the row itself its the volume To add to what Simon has said, if you are looping through a $_POST that many times, then you are sending too much from your form. Instead of using limit in your query (unless you really need to), improve your query...

You'll need to set up a cron job , your host may provide access to this through cPanel etc.. PHP does not stay resident, it executes your script and then closes, so it will not be looking for when you want your next email to be sent. A cron job (in short) is a program that is executed at a set time ...

PHP variables are of the type 'variable'. PHP only concerns itself with what type the data is, when it does something with it, e.g. when it multiplies 2 numbers together. You can force a data type if you need to which is usually called casting - Type Juggling / Type Casting , there is no INT16. You ...

You need to access class properties in a specific way, This (pun intended) might help you.

What errors are you getting and what database are you using?

Check what is in the session:

Code: Select all

session_start();
var_dump ($SESSION)

Then you will be able to see if you have the correct session.

If the session variables are being set correctly, then it is a problem with your code, otherwise it is likely to be a problem with the browser.

There's no need to do this using JavaScript, much less JQuery.

Just use normal HTML and CSS to do it.

Fatal error: Uncaught Error: Call to undefined function arra_keys() in C:\xampp\htdocs\xml.php:5 Stack trace: #0 {main} thrown in C:\xampp\htdocs\xml.php on line 5

Use PDO: Something like this (not tested)- <?php $servername = "localhost"; $username = "username"; $password = "password"; try { $conn = new PDO("mysql:host=$servername", $username, $password); $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); $sql = "CREATE DATABASE IF NOT EXISTS dbp...

<http-equiv="refresh" content="1800"> What follows now is a boiler plate: Learn PDO. You need to make your site as secure as possible and doing from the start will not hurt as much. Is your data really tabular? Learn to use HTML to format your output and CSS to style it. HTML tables used to format ...

Exception is another way of saying error.

It's a poorly written function and I wouldn't use it because, after you call the function you still have to do some testing to see if it's returned what you want.

Your maths is wrong, the number of products that you have purchased has nothing to do with an individual sale. If you just want profit made in currency on an individual sale, you need purchase price , quantity sold and sale price , if you want to know the percentage then all you need is the purchase...

You'll need to use an ftp program to look at what files are there first, but it will be very difficult for us to help as there could be a lot of files.

You have errors in your code, so it fails and does not execute. Enable errors and display errors. I don't know where you got that code from but it's seriously out of date and prone to all sorts of abuse. Don't put CSS in html elements. Verify user input. Include a <title> in your <head> as well as y...

There could be several things going wrong here, it's down to your version of PHP and your settings.

Do you have error reporting switched on and displaying errors?
