[RESOLVED] getting POST variables in a loop

garnetquagga

I'm trying to access POST variables which have numbers at the end by using a loop. Here's a snippet:

for ($i = 1; $i <= $count; $i++) {

  $number=$_POST['itemnum$i'];
  $item=$_POST['newstext$i'];
  echo "<br>i=$i, number=$number, item=$item";

}

This gives me blanks for $number and $item every time. When I do a print_r($_POST); I get the list and the variables are there (itemnum1, newstext1, itemnum2, newstext2, itemnum3 ... ). I just don't know how to reference them.

I don't know if this works or not, but try with double quote signs:

$number = $_POST["itemnum$i"];

Not sure if that will work either, but this should fix any potential issues...

$number = $_POST["itemnum{$i}"]

Funny... I had tried the " " and the {} separately but not together. It works now. Thx.

In this case the braces are not necessary, Piranha's example should work. The problem was that you were using variables in single quoted delimited strings, but for such strings variable interpolation is not performed.

That's true, but I think braces are a good habit to get into. Makes code more readable.
