Foreach multiple select outputs

Question

I have a form which has a multiple option selector in it:

<td>
   <input type="checkbox" name="chk[]" checked="checked" />
</td>
<td>
   <select id="loyaltyType" required="required" name="VX_TYPE[]">
      <option>Choose Type</option>
      <option value="A">A</option>
      <option value="B">B</option>
      <option value="C">C</option>
      <option value="D">D</option>
   </select>
</td>
<td>
   <input type="text" required="required" class="small"  name="VX_NAME[]">
</td>
<td>
   <input type="text" required="required" class="small"  name="VX_EMAIL[]">
</td>
<td>
   <select name="VX_LOCATION[]" multiple>
      <option value="London">London</option>
      <option value="New York">New York</option>
      <option value="Paris">Paris</option>
      <option value="Tokyo">Tokyo</option>
   </select>
</td>

I would like the form to print with the following input/output:

Input:

B, sample name, sample email, New York + Toyko selected

D, sample name2, sample email2, London + Toyko selected

Output:

B, sample name, sample email, New York, Tokyo.

D, sample name2, sample email2, London, Tokyo.

However the actual output I am getting is as follows:

Actual output:

B, sample name, sample email, New York.

D, sample name2, sample email2, Tokyo.

This is the code for the output so far that does not work:

<?php foreach($VX_TYPE as $a => $b){ ?>
<p>
   <?php echo $VX_TYPE[$a]; ?>, <?php echo $VX_NAME[$a]; ?>, <?php echo $VX_EMAIL[$a]; ?>, <?php echo $VX_LOCATION[$a]; ?>
</p>
<?php } ?>

Any suggestions of how to get this working would be great!

assuming you get the following in your post:

 array (
       VX_NAME  =>(
               [1] = sample1
               [2] = sample2
       )
       VX_TYPE => (
               [1] = B
               [2] = D
       )
       VX_LOCATION => (
               [1] = London
               [2] = Tokyo
               [3] = New York
     )
  )

your VX_LOCATION and VX_TYPE selections are going to be put into one array with no association to the NAME,EMAIL. The form gives the user to add additional rows. you will need to associate them to the location/type.

for example:

     array (
       VX_NAME  =>(
               [1] = sample1
               [2] = sample2
       )
       VX_TYPE => (
               [1] = B
               [2] = D
       )
       VX_LOCATION[1] => (
               [1] = New York
               [2] = Tokyo
       )
       VX_LOCATION[2] (
               [1] = London
               [2] = Tokyo
       )
  )

then you can do:

 foreach ($_POST['VX_NAME'] as $k => $v){
  echo $_POST['VX_TYPE'][$k] . "," . $v. ",". $_POST['VX_EMAIL'].",";
    foreach ($_POST['VX_LOCATION'][$k] as $kk => $vv){
       echo $vv . ",";
    }
 echo "<br>";
 }

the form I am pulling from gives the user options to add more identical input rows so the output comes out as an array – user2798841 Nov 16 '16 at 17:31
ok that make sense. I just edited my answer as you commented. does my edit do it for you? – bart2puck Nov 16 '16 at 17:32
I presume you meant: foreach ($_POST['VX_LOCATION'] as $k => $v){ ? – user2798841 Nov 16 '16 at 17:37
Yes, well you are going to have to loop through both if you want all the selected. but yes, in this example $_POST['VX_LOCATION'] – bart2puck Nov 16 '16 at 17:38
this didn't work, the output came up as Array,Array,NewYorkParisNewYorkLondon (as in all the selected options from two inputs printed as one output) – user2798841 Nov 16 '16 at 17:40
that gives me: sample name, sample email, sample name2, sample email2, NewYorkParisNewYorkLondon – user2798841 Nov 16 '16 at 17:50
still no luck. This gives me: sample name, sample email, New York,Paris,NewYork,London, sample name2, sample email2, New York,Paris,NewYork,London – user2798841 Nov 16 '16 at 17:55
this gives the same thing – user2798841 Nov 16 '16 at 18:03
what is this result missing? – bart2puck Nov 16 '16 at 18:04
It gives the same list of locations in each instance @bart2puck – user2798841 Nov 16 '16 at 18:16
what are the key values for VX_NAME and VX_EMAIL? check my update in a minute. – bart2puck Nov 16 '16 at 18:25
