question about $_POST variables

Xephon

I am trying to process a user defined length form (i.e. if the user types in 4, then the form has 4 fields)

And i am trying to process all the fields into an array

I thought a for loop would be best:

the number of fields equal to the amount they chose is printed on the page. Once they fill it in, and press submit i need to process them into an array. I was wondering if this would work:

for($i=1; $i <= $_SESSION['number_of_exercises']; $i++)
{
   $workout_names[$i] = [COLOR=red]$_POST['workout_name$i'];[/COLOR] 
}

will $_POST['workout_name$i']; work? cus i did not know if $i would be processed within the quotes.

also do i need to declare $workout_names as an array, or if i could just make it one by using the statement in the for loop.

Let me know if this is what you're trying to do:

<?php

$workout_names = array();
$j = 1;
for ($i = 0; $i < $_SESSION['number_of_exercises']; $i++)
{
    $workout_names[$i] = $_POST['workout_names'].$j;
}

?>

No, the doesn't get parsed in single quotes. $_POST['workout_name'.$i] Would work. And you should declare the array.

woot thanks for the quick replies and the good info

the reason i did not wanna have to declare it is because it is gonna turn into a multidimensional array in the next step

the array is gonna be structured like this

Workouts -> name1 -> set1 -> reps, weight
                                 set2 -> reps, weight
                 name2 -> set1 -> reps,weight
                                 set2 -> reps, weight
etc etc
