Submitting a multidimensional array via POST with php

Question

I have a php form that has a known number of columns  ex  top diameter  bottom diameter  fabric  colour  quantity   but has an unknown number of rows  as users can add rows as they need    I ve discovered how to take each of the fields columns  and place them into an array of their own    lt input name  topdiameter   current     type  text  id  topdiameter  current    size  5    gt   lt input name  bottomdiameter   current     type  text  id  bottomdiameter  current    size  5    gt    So what I end up with in the HTML is        lt tr gt     lt td gt  lt input name  topdiameter 0   type  text  id  topdiameter0  size  5    gt  lt  td gt     lt td gt  lt input name  bottomdiameter 0   type  text  id  bottomdiameter0  size  5    gt  lt  td gt   lt  tr gt   lt tr gt     lt td gt  lt input name  topdiameter 1   type  text  id  topdiameter1  size  5    gt  lt  td gt     lt td gt  lt input name  bottomdiameter 1   type  text  id  bottomdiameter1  size  5    gt  lt  td gt   lt  tr gt      and so on    What I would like to do now is take all the rows and columns put them into a multidimensional array and email the contents of that to the client  preferably in a nicely formatted table   I haven t been able to really comprehend how to combine all those inputs and selects into a nice array   At this point  I m going to have to try to use several 1D arrays  although I have the idea that using a single 2D array would be a better practice than using several 1D arrays

you could submit all parameters with such naming:

params[0][topdiameter]
params[0][bottomdiameter]
params[1][topdiameter]
params[1][bottomdiameter]

then later you do something like this:

foreach ($_REQUEST['params'] as $item) {
    echo $item['topdiameter'];
    echo $item['bottomdiameter'];
}

On submitting  you would get an array as if created like this     POST  topdiameter     array   first value    second value       POST  bottomdiameter     array   first value    second value       However  I would suggest changing your form names to this format instead   name  diameters 0  top   name  diameters 0  bottom   name  diameters 1  top   name  diameters 1  bottom         Using that format  it s much easier to loop through the values   if   isset    POST  diameters             echo   lt table gt        foreach     POST  diameters   as  diam                    here you have access to  diam  top   and  diam  bottom           echo   lt tr gt            echo     lt td gt     diam  top      lt  td gt            echo     lt td gt     diam  bottom      lt  td gt            echo   lt  tr gt              echo   lt  table gt

I made a function which handles arrays as well as single GET or POST values  function subVal  varName   default NULL  isArray FALSE        isArray toggles between  multi array or single mode       retVal            retArray   array         if  isArray            if isset   POST  varName                  foreach     POST  varName  as  var         multidimensional POST array elements                  retArray    var                                   retVal  retArray             elseif  isset   POST  varName            simple POST array element          retVal     POST  varName              else           if  isset   GET  varName                    retVal     GET  varName         simple GET array element                   else                retVal    default                       return  retVal       Examples    curr topdiameter   subVal  topdiameter     TRUE  3    user name   subVal  user name
