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.

Maybe that is not very helpful, but it's a start

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.
