Please help with if/then statement

So I am not really good at PHP. I can do the basic forms and it works well. Now I am trying something a little more than basic, and I don't know how to do if/then statements. I could pull something out of my butt, but I know that won't work.
The setup:
I am doing an online form for a vehicle carrier. Generally the customer only needs to input information for one vehicle. Sometimes, however, they may need to input information for a few. The vehicle infromation that is essential is 'transportation mode,' 'year,' 'make,' 'model,' 'vin #,' and 'registered owner.' 'Transportation mode' is a multi-choice radio, the rest are text boxes.
Now when you go onto the form, only one vehicle information block is show (called Vehicle #1) , the other four (Vehicles #2-5) are in hidden div tags, once you click on the "Add Another Vehicle" button at the end of one vehicle information block, the next one is shown.
The concept:
Since a client will always have to ship at least one vehicle, the required information for Vehicle #1 will be always in place (you know, if the don't fill in these specific text boxes, they cannot send the form), that part I have down fine. It's the other part that is my problem.
Obviously if they aren't going to be shipping 5 vehicles, I cannot have the form refusing to send because information was not filled out on Vehicles #2-5. I do, however, want some statement that IF the client started filling out information on vehicle 2, 3, 4, or 5, (for example picked the transport mode radio 'mode02') THEN the year, make, model, vin, and owner must be filled out on that vehicles information in order to send the form.
The problem:
I have no idea how to do that.
I hope I have been clear and consice, and I am sure that you guys here can help. I jsut hope I can understand it!
Thanks

It will REALLY help us if you could post the html and php code you have in place now so we don't have to re-invent the wheel - Thx!

I guess you have done BASIC, if you are calling it an if/THEN statement. There is no 'then' command in PHP, it uses C style with {} to encase the statement.
PHP Code:
if (condition) {
statement; //comment
}
Maybe that is not very helpful, but it's a start

I am sure I am going to do something really stuipid, probably post more than you need..... But you don't need to re-invent the wheel.
And Wayfarer07, oh yeah, I had a semester of VB like 8 years ago. So please pardon the fact I don't really know what I am talking about.
Also, I guess since were here, if possible, I would really like the email the form is sending and output page only give information on the additional vehicles if they fill in those fields. For example, if they fill in the information for vehicle one, then 2,3,4 and 5 don't get sent. if they do 1 & 2, 3,4 and 5 don't get sent, etc etc. If I'm asking too much, or you think too much for my skill level, then please by all means, let me know. 
FYI, you can see my test page hands on at:
http://clrauto.cgsart.com/shippingorder.html
Feel free to play with it. The emails are being sent to me, so it's OK to hit subhmit to see th output page.

http://us3.php.net/manual/en/control-structures.if.php states otherwise, you don't need brackets for single items/lines, and if I remember right that's how C is too. Haven't used C in a while though. That PHP is based off of C has a lot to do with it I'm sure. Anyway conditional statements or control flow structures are often referred to by their nickname of if-then-else or just if-then statements, it describes how they work, BASIC was created to be very simple and went a tad further. In php this works in the order of:
if() // The if
{} // The then
else() //The else
Those who have used any professional references (sites, books etc) would be familiar with the term, those who taught themselves from help forums such as this may never have encountered the term. http://java.sun.com/docs/books/tutor...dbolts/if.html java has no 'then' but the official tutorial written by the creators calls the conditional statements by the name if-then.

Let me begin by apologising, firstly I'm not a PHP programmer, but I did write C for many years and the syntax is very similar. Secondly, I'm going to lapse into pseudocode after a bit.
Instead of processing 5 different sets of data, why not put them into a set of 10 arrays:-
$via[1] = Trim(stripslashes($_POST['via1']));
$running[1] = Trim(stripslashes($_POST['running1']));
$year[1] = Trim(stripslashes($_POST['year1']));
$make[1] = Trim(stripslashes($_POST['make1']));
$model[1] = Trim(stripslashes($_POST['model1']));
$color[1] = Trim(stripslashes($_POST['color1']));
$license[1] = Trim(stripslashes($_POST['license1']));
$vin[1] = Trim(stripslashes($_POST['vin1']));
$reg[1] = Trim(stripslashes($_POST['reg1']));
$via[2] = Trim(stripslashes($_POST['via2']));
$running[2] = Trim(stripslashes($_POST['running2']));
$year[2] = Trim(stripslashes($_POST['year2']));
and so on.
Then you can use a loop construct "for" to process each potential vehicle
This way you only have to write the code once, not 5 times and it's far easier to maintain.
/* pseudocode */
create start of email;
for ($i=1; $i<=5; $i++)
{
/* do we have a valid "ith" vehicle */ if ($via[$i] through reg[$i] are all empty)
{ do nothing;
/* no data for ith vehicle */
}
else
{ validate 6 mandatory values;
if (validate OK)
{ /* build section of email */
$Body .= "-- Vehicle ".$i." --\n\n";
$Body .= "Transportation via: ".$via[$i]."\n \n";
$Body .= "Is the vehicle in running condition? ";
$Body .= $running[$i]."\n\n";
etc. etc.
}
else
{/* this only has to be done once if you put it here */
die ("<input type='button' value='Back' onClick='history.go(-1)'>");
}
}
}
append rest of email;
send email;
The HTML echo of the data for the optional printed page can be generated in a similar manner. |

I'm not sure what pseudocode is, but I will look into this and see if I can understand it.
Thanks.

From Wikipedia:
Quote:

Pseudocode (derived from pseudo and code) is a compact and informal high-level description of a computer programming algorithm that uses the structural conventions of some programming language, but typically omits details that are not essential for the understanding of the algorithm, such as subroutines, variable declarations and system-specific code. The programming language is augmented with natural language descriptions of the details, where convenient, or with compact mathematical notation. The purpose of using pseudocode is that it may be easier for humans to read than conventional programming languages, and that it may be a compact and environment-independent description of the key principles of an algorithm. No standard for pseudocode syntax exists, as a program in pseudocode is not an executable program.

So for example
"if($via[$i] through reg[$i] are all empty)"
stands for something like
if( empty($via[$i]) && empty($running[ $i] ) && empty($year[ $i] ) && empty($make[ $i] ) && empty($model[ $i] ) && empty($color[ $i] ) && empty($license[ $i] ) && empty($vin[ $i] ) && empty($reg[ $i] ))
Note the use of && rather than "and" - see your PHP manual for "Operator Precedence"
BTW, in my previous post, when I said 10 arrays, I miscounted, should have been 9.
Not got a PHP manual? Have a look at http://www.w3schools.com/PHP/php_if_else.asp for more if / else / elseif help

Excellent! Thank you!
I haven't had a chance to look at it yet, but I will tomorrow.
