Array assignment probelm

[Xephon]

what is wrong with this code? i dont see what i did wrong.

             $workout_name = array();
             $k=1;
             for ($i = 1; $i <= $_SESSION['number_of_exercises']; $i++)
                 {
                     $workout_name[$i] = $_POST['workout_name'.$i];
                     $j = $_POST['number_sets_exercise'.$i];
                     $workout_name[$i][$k] = array();
                     $workout_name[$i][$k] = range(1, $j);
                     $k++;

             }

all i get is errors like this

Notice: Array to string conversion in C:\Apache2\htdocs\workout\enter_workout.php on line 47

Notice: Array to string conversion in C:\Apache2\htdocs\workout\enter_workout.php on line 48

btw im trying to fill in a 2-d array with values posted from another page

Could you post all the code? If not can you at least tell us which lines are 47 && 48?

One thing I can spot is this

$workout_name[$i] = $_POST['workout_name'.$i];

is setting $workout_name[$i] to a string (t may be an array but you haven't given us enough info. so I'm assuming it's not) but latter you're trying to make it an Array which doesn't make sense.

the first page is the php code (enter_workout.php) and the 2nd page is the smarty template (enter_Workout.html)

my goal is for the code i posted to make an array like this:

$workout_name = array( "Workout_name_1" = array( 1,
                                                 2,
                                                 3
                                                 );
                       "Wrokout_name_2" = array( 1,
                                                 2,
                                                 3,
                                                 4,
                                                 5
                                                 );

where workout_name_1 and workout_name_2 are the names the user picked on the previous form (i.e. Bench press, Incline press), and the arrays asssinged to each, are the set numbers.

The next from is gonna put an array into each set number for the amount of reps, and the weight used per set.

btw i just updated the code, it is getting closer to working, but for some reason it shows one less exercies name than it should, and way more rows per exercie than it should

say i enter 3 different exercise names, and 6 sets for the first, 5 for the 2nd and 4 for the 3rd i get this output

for($k=1; $k <= $j; $k++) {
  $workout_name[$i][$k] = array("set_number" => $k);
}

This makes no sense, it's redundant data. You're going to end up with array elements from 1 to $j containing just the key 'set_number' and the iteration value, why not just store $j in an element and iterate whenever you need to.

If this arangement is totally necesarry you will want to look at restructuring your array because at the moment each element of $workout_name[$i] is an array with keys consisting of both strings and integers. Although not syntactically incorrect this may cause confusion when you attempt to itterate through it. It may be a better idea to have an extra element in $workout_name[$i] and have this a numeric array containing the data, so $workout_name[$i]['set_number'][$k]. However, first I think you need to have a good think about whether that section of the array is really necesary at all.

i am wanting to make the array like this

$workout_name = array( "Workout_name_1" = array( 1,
                                                 2,
                                                 3
                                                 );
                       "Wrokout_name_2" = array( 1,
                                                 2,
                                                 3,
                                                 4,
                                                 5
                                                 );

where workout_name_1 and workout_name_2 are the names the user picked on the previous form (i.e. Bench press, Incline press), and the arrays asssinged to each, are the set numbers.

The next from is gonna put an array into each set number for the amount of reps, and the weight used per set.

If you want arrays that look like (1,2,3,4,5), then your code could be simplified by using [man]range[/man].
