If you want to update the page without reloading it you will have to use client side scripts such as Javascript. (PHP is a server side language and so all the php is executed before the page is sent...

I'm assuming it's just a bad tut because of the lack of attention to detail and testing. The @ symbol was never for variables.

It seems there is an error in the tutorial you are using. the "@" symbol is actually used to suppress an error that the following function might throw: http://www.tuxradar.com/practicalphp/19/8/12

I'm not that familiar with streaming video but I'm quite sure that if you want the browser to show something, you must tell it where it is. The browser then determines what to do with it, so it can...

For each user you want to check, you would do something like this:
1. Get the timestamp for this user from the database
SELECT last_activity FROM user_activity WHERE id=$id
2. Compare this...

Sorry for not getting back to you about my idea. What I meant was, you store the timestamp for each user's last activity in the database. Then any time you want to check if someone is "active" you...

Don't worry CFROG, I still do it. You skim over your code and remember what you should be there instead of reading what is there. Another set of eye's can spot it in no time. :P

Holy Moley, you'll hate your self for this :P You forgot a crucial line: mysql_query($sql); which should go on line 16. As your code stands, it doesn't execute the new SQL command, just sets the $sql...

The easiest way to do this would be to set a column "lastactivity" to the current time every time the user loads any of your pages (just build it into your authentication script). You can then...

The problem you are having is with your double quotes.

echo "value of the constant CONSTANT: " . CONSTANT;

You can use a for loop to operate on each element of the array. I'm assuming it's a one (meaningful) columned table.

//len is length of array
for (i=0; 0<len; i++){
//create SQL statement

Might also be a good idea to do

if (!mysql_query($sql)){
die (mysql_error());
}

Your form should look like this:

<form ...>
<input type="hidden" name="student" value="$row['student']" />
<input type="submit" name="delete" value="Delete" />
</form>


Then you can get...

You could even use an "INSERT ... ON DUPLICATE KEY UPDATE ..." query (if you have a primary key "id" column) but that's getting complicated.

I am not going to write your code for you - that's the sort of thing I get paid for :P - but I will help you do it yourself.

The way I would do it is as follows:

You need to post the relevant code for anyone to know what's going on. Is the code that checks the input data and the code that displays the input boxes on the same page? Does refreshing/reloading...

How is your database set up? That will only work if

a variable (such as $myusername) must be set in the same script for it to have a value, and thus be echo'd to the page. This means the value will be lost if the user refreshes the or follows a link. ...

Hmm, you've got an input for the quantity. Did you add that in the hope of getting it to work? Does the cart work how it is without quantity? What do you actually mean by "add the amount of items in...

Are you using a session to store the stuff in the cart or what? I'd suggest creating a session for the user with the following variables:

array $quantity
array $product

Using any program that can use sockets you can do this. If you have php installed on your computer then that's easy. I have done it with Game Maker (using 39dll) before.

What you need to do is...

There are functions for including in a script, a script held in another file. Is this what you mean? i.e. you can define the functions that you will use (and constants, variables, etc) and then...

Ok, you need to look at a few tutorials (there's millions on the net) about user logins and sessions. In a nutshell:

<form action="submit.php" method="GET">...

As PHP is a server side language, PHP can't be used to modify the page once it has been sent to the browser. You need a client side language (that is executed by the viewers browser) such as...

To have less of an impact on the server at runtime I'm guessing 2) would be much better as in 1) you must load the entire history of news items into memory as opposed to about 30 bytes per news item....

Are you saying "www1" is to www1.example.com as "mail" is to mail.google.com? Does this mean that "www" a subdomain but many modern web servers are able to assume a subdomain of "www"...

first, after $find_ad has been set, I would split the data by $list = explode("</tr>",$find_ad) then do a replacement on each item like so:

Thanks for that last bit of info, it has actually made my requests successful. You've been a big help because HTTP headers is something I have only briefly read over.

Cheers.

Notice how line 24 of my code includes "GET" and not "POST"? That's the call I used to (successfully) send a GET request (as the English above clearly states).

I have slightly modified the code...

What exactly are you asking for? What is a word "we like"? It will probably be possible to write a function to do what you want but I'm not entirely sure what that is.

All in all, what info do you...

In php, if you try to perform an operation on $start_time (assuming that it is a variable in the script containing a string) it will be used as an integer. It works fine if the string is something...
