Html PHP - Form - Input as array

Question

I got a form like this   lt form gt   lt input type  text  class  form-control  placeholder  Titel  name  levels level   gt   lt input type  text  class  form-control  placeholder  Titel  name  levels build time   gt    lt input type  text  class  form-control  placeholder  Titel  name  levels level   gt   lt input type  text  class  form-control  placeholder  Titel  name  levels build time   gt    lt  form gt    What I d like to have as   POST output is an array like  Array       1    gt  Array    level    gt  1  build time    gt  123       2    gt  Array    level    gt  2  build time    gt  456       I know I could do something like name  levels 1  build time   and so on but since these elements get added dynamically  it would be hard to add an index  Is there any other way   EDIT   As suggested  I changed my form  I also included my whole HTML now  because I think I m missing something here  My HTML now    lt div class  form-group  gt     lt label class  col-md-2  gt Name z B  1  lt  label gt     lt div class  col-md-10  gt       lt input type  text  class  form-control  placeholder  Titel  name  levels   level   gt     lt  div gt      lt label class  col-md-2  gt Bauzeit In Sekunden  lt  label gt     lt div class  col-md-10  gt       lt input type  text  class  form-control  placeholder  Titel  name  levels   build time   gt     lt  div gt   lt  div gt    lt div class  form-group  gt     lt label class  col-md-2  gt Name z B  1  lt  label gt     lt div class  col-md-10  gt       lt input type  text  class  form-control  placeholder  Titel  name  levels   level   gt     lt  div gt      lt label class  col-md-2  gt Bauzeit In Sekunden  lt  label gt     lt div class  col-md-10  gt       lt input type  text  class  form-control  placeholder  Titel  name  levels   build time   gt     lt  div gt   lt  div gt    The output I get now is    levels    gt  Array       0    gt  Array    level    gt  1       1    gt  Array    build time    gt  234       2    gt  Array    level    gt  2       3    gt  Array    build time    gt  456        Edit 2   As suggested in your edit  I edited my form and moved the square brackets to the end of the name  The output I get now is    levels    gt  Array       level    gt  Array         0    gt  1       1    gt  2          build time    gt  Array         0    gt  234       1    gt  456           I guess that would kinda work but it still looks complicated  No better way

Simply add    to those names like    lt input type  text  class  form-control  placeholder  Titel  name  levels level     gt    lt input type  text  class  form-control  placeholder  Titel  name  levels build time     gt    Take that template and then you can add those even using a loop   Then you can add those dynamically as much as you want  without having to provide an index  PHP will pick them up just like your expected scenario example   Edit  Sorry I had braces in the wrong place  which would make every new value as a new array element  Use the updated code now and this will give you the following array structure  levels  gt  level  Array  levels  gt  build time  Array    Same index on both sub arrays will give you your pair  For example  echo  levels  level   5   echo  levels  build time   5

If is ok for you to index the array you can do this    lt form gt       lt input type  text  class  form-control  placeholder  Titel  name  levels 0  level   gt       lt input type  text  class  form-control  placeholder  Titel  name  levels 0  build time   gt        lt input type  text  class  form-control  placeholder  Titel  name  levels 1  level   gt       lt input type  text  class  form-control  placeholder  Titel  name  levels 1  build time   gt        lt input type  text  class  form-control  placeholder  Titel  name  levels 2  level   gt       lt input type  text  class  form-control  placeholder  Titel  name  levels 2  build time   gt   lt  form gt        to achieve that    levels    gt  Array       0    gt  Array         level    gt  1       build time    gt  2          1    gt  Array         level    gt  234      build time    gt  456         2    gt  Array         level    gt  111      build time    gt  222           But if you remove one pair of inputs  dynamically  I suppose  from the middle of the form then you ll get holes in your array  unless you update the input names

HTML  Use names as   lt input name  levels level     gt   lt input name  levels build time     gt    PHP    array   filter input array INPUT POST    newArray   array    foreach  array keys  array  as  fieldKey        foreach   array  fieldKey  as  key  gt  value             newArray  key   fieldKey     value               newArray will hold data as you want  Array       0    gt  Array    level    gt  1  build time    gt  123       1    gt  Array    level    gt  2  build time    gt  456

in addition  for those who have a empty POST variable  don t use this   name   levels  level       rather use this  as it is already here in this example    name  levels level
