It can be used for about anything really... not just web pages. From the manual:

So you could use it to make a PHP based telnet client, proxy server, or really about anything else you want. That's...

cURL is pretty diverse. It can be used for just about anything. That diversity makes it hard to recommend one good tutorial because it really depends on what you want to use it for.

I would first...

The first thing that jumps out at me is: curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
You may want to change $ch to $crl

The @ symbol prevents PHP from displaying errors associated with that expression. In my opinion, it's the lazy way of making a directory without checking first if it already exists and if you have...

There's always cookies, but that's not a good way to pass info dynamically. Cookies are more for persistent data.

You also don't need to quote numbers if the data type for the field is set correctly.

No problem.

$subject = $_POST['radiobuttonfield'];

Sessions work equally as well on one page. It doesn't have to be multiple pages at all.

If all you're trying to do is prevent another add if the user presses the refresh button, then you don't really need to add anything to the form. You can do it all with the session.

On line one:
...

I'm also a fan of blocks.


<?php

if ($ampm == 0 && $hr == 12) {
$hr = 0;
} else if ($ampm == 1 && $hr < 12) {
$hr = $hr + 12;
}

Yeah, I wouldn't suggest using sessions to build the menu ... just to "expand" the active menu section. I assume you use some JS to expand the sub-sections (IE: Music) when a user clicks on that...

Try this, replacing the value of $to with your actual email address:


<?php

$subject ="Contact Form";

$info="Test Info Value";

$mail_from="nobody@nowhere.com";

Using die() will halt the execution of the script. Nothing beyond that will be processed. Instead of using die() you could just store the error in a variable and echo it in your error box or where...

At quick glance it looks like all your code to write to the file comes after you read the file. If you write the information submitted from the form BEFORE you read the file and count the lines, you...

It would also help if you told us the line number that the error is returning.

Yeah, I'd go with the session option.


<?php
session_start();
$_SESSION['cur_nav_section'] = 'Music';
?>


Then use that variable to open your nav menu to the correct section on page load.

Yeah, I don't mind helping either, but I usually charge to do freelance work.

Where are you connecting to the database? Does your function have access to the resource variable?

I try to use built in functions for validation where I can. PHP has decent email validation with filter_var


$is_valid = filter_var($email, FILTER_VALIDATE_EMAIL);

"It's not working" is pretty vague. Are you getting any errors? Is the page echoing "ERROR"? Does everything "seem" to work, only you never receive the email? What do you get if you put var_dump($to,...

No problem. I try to help when/where I can. I'm just sorry I didn't have a better solution to offer. I've never been a huge fan of theming apps. In my opinion it can be a pain in the backside. But...

I think the closest you're going to get to something like that would be to use a provided API from one of the carts that allows you to do your own stuff from any page. Prestashop offers a decent API...

You can always print the variables, then use a scanner. Fax is pretty reliable too ;)

Your only real "limit" on how big your database can be is the hard drive on your server.

Unless you have more than a "gazillion" friends, I doubt you have to worry about drive space. Like NoDog...
