Setting Program within a While Loop

[millsy007]

I have a system that is booking people in, sometimes the user will want to make a multiple booking, so I have added a drop down list with the number of passengers to add

My program then reads this in as a variable

 

$passengers = $_GET['passengers'];

 

I then want to loop through for each of the passengers:

 

while ($passengers != 0) { // At the start


//Put the rest of my program withing this


$passengers= ($passengers-1) //At the end 
}

 

Is this a sensible way to do things, I wanted to check before I tried as I know loops can go horribly wrong!

If I understand you correctly:

( if user chooses for example 5 passengers, you want to display 5 consecutive pages for passengers' details)

 

this is not how you would do that

[cooldude832]

This screams some sort of OOP setup

 

 

or at the very least a function to do this.

 

 

I think if you are looking to enter 5 duplicant rows into MySQL then you should do it in a single query and only need to run the processor checking once

The program currently works one booking at a time, the user selects the date and route, enters the passenger name and clicks 'book' however sometimes someone will want to make a booking for say 5 people so instead of clicking 'book' 5 times I want them to enter the number from a list, and then the program basically repeat the insert code 5 times.

So you want to display a single form for 5 clients. Yes, you can do that using while loop   Although for might be better.

[millsy007]

Hi yes, its one form, but the input would be done 5 times.

 

So in my page a makebooking.php is called in which the booking queries are ran, this is what I was thinking of enclosing within my while loop as per the original post, what would the advantage of a for loop be?

[Mchl]

It would look more intuitively IMHO.

 

for($i=1;$i<=$passengers;$i++) {
//your code
}

 

Other than that it works just like while()

[millsy007]

So if I passed in the variable $passengers and this had a value of 5 would that code go through 1 at a time until all 5 had been inserted?

[Mchl]

Basically yes. Read the manual for for for detailed information on how it works.

 

Yes... I purposefully put triple 'for' in above sentence.

[millsy007]

I get:

Cannot redeclare insert() (previously declared in /home/makebooking.php:92)

What I want to do is literally run all my code for the amount of passengers, but it looks like this may cause problems?

Hi

 

Can you post up the source code?

 

All the best
