Re: test PHP in WAMP without internet connection

Hosted on an external server? I am using WAMP which means my server is my computer. So, does it mean that i can actually run my php-mysql script in my machine without internet connection? thank you!

The meaning is, if all the pages and resources (like images et al) are found in local server then you can use it with no internet connection at all. Otherwise you need internet connection

Re: Need a good website to download some header files

If you install gcc or Dev-C++ you might be able to compile it ok. I

AD,
DevCpp died way back and its MinGW version is likely to be outdates. I know two actively developed IDE both with Mingw bundle and both supports vc compiler too. They are like Essau and Jacob you know: CodeLite and Code::Blocks

EDIT:
I was a bit quick and slipped on previous post.
I think DevCPP site should close and let wxDevC++ be its successor as it is actively developed

Re: Form Post to DATABASE from MySQL Query output

It is hard to help with such massive codes.my advice is, make small code based on your above code, and poke with it until it works then incorporate the idea in your big project.

I will help if you reduce to something readable :)

Re: What is wrong with this update?

Here is simple form,
take it as assignment and play with it to use update and other queries.
Use it as your toy for learning

<?php
$first_name = $_POST['fname'];
$last_name = $_POST['lname'];
$email_name = $_POST['email'];

$sql = "INSERT INTO address(firstname, lastname, email) VALUES('$first_name', '$last_name','$email_name')";
mysql_query($sql);

?>
 
<html>
	<body>
		<form action<?=$_SERVER['PHP_SELF']?> method="POST">
			<input type="text", name="fname" />
			<input type="text", name="lname" />
			<input type="text", name="email" />
			<input type="submit", value="Send" />
		</form>

Re: Help in OOP

If that advice is good then stop what you are doing :)
Here are good resources but RTM is important!
1. Get acquainted with TCP/IP and sockets in general
2. Get the basics of QT after C++ of course!

Grab QT Book and get head up with the QT Network tutorial. Also QT site have got examples. Please surf through developer section

Re: Help in OOP

why using Windows thing in QT, I mean QT is designed to be Xplatform and using windoish stuffs limits the very purpose. If you plan to use it in windows then go for Win32 API, or stay away from windowing and do it QT way :)

Having said so, I suggest Zetcode QT tutorial as one of Good start

Re: Data access Layer Design with C++

Since no body have answered, I will pretend it to be unclear, let me get to the heart where I hit a wall. I know how to get stuffs from DB, and I know how to use them (In normal app) but have never done UI-BLL-DAL application and I was wondering how I can implement that. Main issue is what should BLL send and what should DAL return.

Many articles just say I should not send queries/concatenated query strings and they don't say what should I do as alternative. They talk about structure but i'm yet to find an article on how to actually d it.

Many examples are .Net specific, ADO.NET etc. I cannot find any example in C/C++ or Python, PHP which I'm conversant

If You have not understood my question/point I'll be happy to clarify

Data access Layer Design with C++

Hi,
I'm trying to develop application with separation of UI/BL/DAL.
I have read a lot of theories and I'm trying to develop a blue print for my application.
I have no problem in UI thing. But I have problem with designing Data Access Layer.
It will basically be a SQLite database backend (I may add other backends as well as XML).
Now I don't know how to write class(es) to do the DAL. So please help me get on it, perhaps with very simple example.

Thanks

Re: Need help on this one. :(

Just store the words in a std::vector<std::string> and then output the appropriate word with std::cout << words[i]; . You could alternatively use a switch statement.
In the future, please use more descriptive thread titles!

I agree with you Dave, but since he said is newbie I think he should start with std::string array[] before moving to STL

Re: list of most used php function

Your initial statement / request is almost as unrealistic as:
"I am a PHP programmer. I need to build a bridge. I don't have the time to learn all about civil engineering. Just tell me the most common design approaches for building a bridge so I can get on with it."

Nail on head. If you don't know it and you want to use it but you don't wan't to learn it, then you can't do it. I will suggest that you hire someone with time to do it and you pay him/her for that time.

Sorry but that person can't be me, I have no time ;)

heyy thnxxxzz... itz worky bt i dont need to get all fields in the form.. there are another text fields also. thn how i get only set of text fields that i want.

Looping in this case is impractical because you will need a lot if if..else if..
Just retrieve them using normal way

Now I suspect something is wrong with your if..else
Here is my suggestion:
add the files in the comments below

}
else{
    //paste code for second file
}

Paste two files differently if you will still face errors

echo'<form name="form1" method="post">';
echo '<div>';

Re: client side and server side

Here is summary of what happens.
Client (mostly web browser) sends HTTP request to the server. The server processes the request with right file and then returns a response in terms of HTML or JSON et al.
So the Client doesn't know about server code and server about client. They only know of requests and response
