PHP Content Issues: Array $ _POST

Question

I am going to ask a question about the problem that I have, and try to figure it out based on your guys. I will send the source code if I REALLY cannot get it, but here I go ...

So, I have a form that displays the fields vertically. All this is a drop-down menu, and at the very end is the submit button. There is sprinkled with javascript, which allows me to add a new line without refreshing the page. Thus, for each key, there are never as many $ _POST arrays. The key that excites me (well, all of them, but as soon as I earn it, it works for everyone) is a fall $_POST['monworkhours']. This is a drop-down list with a list of different hours of work. I believe the problem is that I need to scroll through the entire array $_POST['monworkhours']based on the view. I do not know how to do that.

In addition, the “problem” produces the same results for each line of output. Therefore, everything that I set for the first field becomes the result for each additional line that I added "through" through the javascript function.

Any help is appreciated.

The form:

<select name="monshifthours[]" id="monshifthours">
        <option value="OFF">OFF</option>
    <optgroup label="Front/Back Half">
        <option value="7am7pm">7AM-7PM</option>
        <option value="7pm7am">7PM-7AM</option>           
        <option value="7am7pmalt">7AM-7PM (Alt)</option>
        <option value="7pm7amalt">7PM-7AM (Alt)</option>
    </optgroup>
    <optgroup label="Monday - Friday">
        <option value="630am330pm">630AM-330PM</option>
        <option value="7am4pm">7AM-4PM</option>
        <option value="8am5pm">8AM-5PM</option>
        <option value="10am7pm">10AM-7PM</option>
    </optgroup>
  </select>

The output of $ _POST (2 lines of lines):

 ["monshifthours"]=>
  array(2) {
    [0]=>
    string(6) "7am7pm"
    [1]=>
    string(6) "7pm7am"
  }

Screenshot:

GetCellColor () function:

function getCellColor($dow) {
      foreach($_POST[$dow . 'shifthours'] as $key=> $hour) {
          echo $count;
          if ($hour == "7am7pmalt") {
              return "style=\"background: yellow; color:#000;\"";
          }
          elseif ($hour == "OFF") {
              return    "style=\"background: red; color:#fff;\"";
          }
          else {
              return "style=\"background: green; color:#fff;\"";
          }
    }
}

For output:

if (isset($_POST['submit'])) {
    echo preTableFrmt();
    foreach($engineer as $a => $b) {
        echo "| [[$engineer[$a]]] || ".getCellColor('mon')." | $monday[$a] || ".getCellColor('tues')." | $tuesday[$a] || ".getCellColor('wed')." | $wednesday[$a] || ".getCellColor('thur')." | $thursday[$a] || ".getCellColor('fri')." | $friday[$a] || ".getCellColor('sat')." | $saturday[$a] || ".getCellColor('sun')." | $sunday[$a] <br />|-<br />";
    }
    echo postTableFrmt();
}
else { echo "Waiting for data..."; }

Note. When sending one line of the form, everything is in order; this is when I have more than one; then I get duplicate information.

The following example should show you what happens when I “add an engineer” (now doing two lines of lines). I will post the result after the image:

$_POST ['monworkhours'] :

foreach ($_POST['monworkhours'] as $i => $value){
    // Do something
}

As a suggestion, I would like to describe things like Patrick Fisher in his answer.

<select name="aa_1"> <select name="bb_1"> <input type="hidden" name="lines[]" value="1" />
<select name="aa_2"> <select name="bb_2"> <input type="hidden" name="lines[]" value="2" />
<select name="aa_3"> <select name="bb_3"> <input type="hidden" name="lines[]" value="3" />

Thus, as soon as you submit the form, you can get each element of the form horizontally (i.e., rows), and not vertically.

foreach($_POST["lines"] as $key => $value) { 
    ${"aa_".$value} = $_POST["aa_".$value];
    ${"bb_".$value} = $_POST["bb_".$value];
}
