Hi again.

would anyone explain to me how/ if i can set a loop that will increment the variables in it by one with each revolution?

for example: id like the first loop to read from $_SESSION[apwidth1] but the 2nd loop to read from $_SESSION[apwidth2]


1st time:

for(1;$numbeds;$i++)
{
$_SESSION[apwidth1]
}

2nd time:

for(1;$numbeds;$i++)
{
$_SESSION[apwidth2]
}


Obviously my loop will be a little more sophisticated, its just an example.


To put you in context im designing a website for a sliding wardrobe door company. it will enable customers to enter an aperture width/height, and the php will decide how many doors of what size they require. then the customer will choose a colour and the php will look to mysql for the price of however many doors of what size in their chosen colour and output a total price. I finished the php/ mysql section yesterday and ive been informed today that most customers have more than 1 bedroom and therefore need more than 1 set of doors (up to 4), so without duplicating my php 4 times (which would be a very long haul) id like to set a loop that rotates for $numbeds(number of bedrooms) and increments the variablenames involved within it by 1 each time so when it comes to the end and the total price of each bedroom is calculated i will end up with bed1price +bed2price +bed3price, as opposed to bed1price + bed1price +bed1price.... Am i asking too much?????

Thanks guys

for($i = 1; $i < $numbeds; $i++)
{
$_SESSION["apwidth$i"];
}
This should do the trick.

excellent... it's that simple. nice work

It was that simple until i wanted to make another loop to show the results, how can i make this loop work any ideas?

PHP Code:

for($i = 0; $i < $_SESSION[numbed]; $i++)
{

echo"   bedroom$i aperture is
 
$_POST[apwidth$i] mm wide x $_POST[apheight$i] mm high"; 


The error i get says expecting ] on the line which starts $_POST[apwidth$i]. Ive tried putting ' and " tags all over the place, basically what im asking is how can i make the php read $i if its enclosed in []?

above is the results page of the form shown below.

PHP Code:


<?php
session_start();

//$_SESSION[numbed] refers to the previous page where the customer would've entered the number of bedrooms they want wardrobes for.

$_SESSION[numbed]="$_POST[numbed]"; 

{
 echo
    " Enter your apperture size/s in mm<br>";
}
for($i = 0; $i < $_SESSION[numbed]; $i++)

{
echo"
      <form action='doorselector.php' 
            method='post'>\n
Bedroom $i: 
      <input type='text' name='apwidth$i' size='4' maxlength='4'>\n
 wide x
      <input type='text' name='apheight$i' size='4' maxlength='4'>\n
 high <br><br>\n";
}
echo"
<input type='submit' value='send'>\n
      </form>\n";
?>

PHP will only expand variables out if they are in quotes. It might do this for the first one ($_POST) but then the inner variable confuses it.
Generally when doing this with arrays I play it safe and break the string up:

PHP Code:

echo"   bedroom$i aperture is ".$_POST["apwidth$i"]." mm wide x ".$_POST["apheight$i"]." mm high"; 


excellent. thanks very much oberon it works fine now
