O.P. Check for input and post to PHP
first of all: hey! im teh new one!!11 8-|

i got a lil script knowledge issue:

imagine a window with 3 editable text inputs. text1, text2 and text3.
at the bottom i got a submit button.

what i dont know:

i need to check all of the 3 texts boxes for emptyness! if text1 empty -> error msg, else if text2 is empty msg -> error else if text 3 is empty -> error msg

if all of them are fillled with text, they should be put in a variable seperately. e.g. t1, t2 and t3, because i want to put them into a post script later for a mysql_query.

i guess this one would work with my idea: http://shoutbox.menthix.net/showthread.php?tid=82911

would be fine if someone could assist me.

EDIT: they dont need to be seperately at all :)

Did you check the Scripting Documentation?

In there you will find that when they press the button you can use

code:
if ( pPlusWnd.GetControlText("Text1") === "" ) {
    // error
}

That is what matty's code does, it checks if the textbox is empty.
You could also/alternatively add a check in your PHP code:
code:
if ($_POST['t1'] == "") {
    // error
} else {
    // continue
}

RE: Check for input and post to PHP
Yes, that thread will help you out with most of your problems about sending the information. Checking for emptiness isn't that hard either.
Here's some kind of scheme which you should base your code on.
  1. Make a function for your window's CtrlClicked event:
    code:
    function OnWindowIdEvent_CtrlClicked(PlusWnd, CtrlId) {
       ...
    }
  2. In that function, check if the CtrlId matches the ID of your submit button.
  3. If it matches, we'll firstly have to get the three text inputs:
    code:
    var t1 = PlusWnd.GetControlText("text1");
    var t2 = PlusWnd.GetControlText("text2");
    var t3 = PlusWnd.GetControlText("text3");
  4. Then, we'll check the emptiness:
    code:
    if(t1 == "" || t2 == "" || t3 == "") {
       //Show an error message.
       //For more information, check the MSDN page of MessageBox.
       //http://msdn.microsoft.com/en-us/library/ms645505.aspx
       Interop.Call("user32", "MessageBoxW", 0, "A required field has been left empty.\nPlease check your inputs and try again.", "Field left empty", /* MB_ICONEXCLAMATION */ 0x30);
    } else {
       //Input is valid, send the information to the PHP page!
       ...
    }
  5. If it's not empty, the information can be sent to the PHP page by using the method explained in [Tutorial] Communicating with web pages. Depending of how your PHP page wants to receive the information, you can either send it using GET or POST. The tutorial explains it very well, I'm sure you'll find out what you have to do. :)

Yes, the error stuff can be done with a call to MessageBox. ;)
(The W after the function's name indicates that the Unicode version should be used, it's not a typo!)

You should have that code in your PHP anyway to prevent malicious attacks, but a check in the script itself is more useful because you can get a nice error box before any data is transmitted. I recommend using both for the best experience for both you and the users! (y)

code:
function OnWindowIdEvent_CtrlClicked(PlusWnd, CtrlId) {
   if(CtrlId == "BtnSubmit") { // Thats Point #2 to check whether its the submit button clicked. Replace BtnSubmit with whatever ID you've given to the submit button
    var t1 = PlusWnd.GetControlText("text1"); //Point #3
    var t2 = PlusWnd.GetControlText("text2");
    var t3 = PlusWnd.GetControlText("text3");
