I am trying to pass some data from a form to another page. In the destination page I want to get the data with $_POST and check if the fields are filled or not .if a field is not filled , the it takes the value of zero . I am trying to do this with loop for because I have 32 form values but even if I write something to the fileds I always get the value of zero...The check code is here:

//check form fileds
for ($i=18;$i<=49; $i++) {
if (isset($_POST['r$i']))
$v[$i]=$_POST['r$i'];
else
$v[$i]="0";
}

Can anyone help ?

using single quotes in this: $_POST['r$i']
will cause the engine to NOT to evaluate the value of $i !
instead use double quotes

PHP Code:

//check form fileds

for ($i=18;$i<=49; $i++) {

   if (isset($_POST["r$i"]))

      $v[$i] = $_POST["r$i"];

   else

      $v[$i] = 0;

}

I know the other code worked for you but you might want to try this because this will be more reusable.

PHP Code:

foreach($_POST as $key => $value){

        if(empty($value))

              $_POST[$key] = 0;

}
