To summarize from a previous question, the user selected a starting date, an ending date, and a region. From these choices, an array of weeks and regions are created, and users enter values ("points") that correspond to a particular week and region. This is what it looks like right now (some parts are hard-coded for testing purposes):
$date_array = Array("01/01/2012", "01/08/2012", "01/15/2012"); $region_array = Array("NYC", "DC"); <form name="test_form" id="test_form" method="post"> <table border="1"> <tr> <td></td> <?php foreach ($date_array as $date) { echo "<td>".$date."</td>"; } ?> </tr> <?php foreach ($region_array as $region) { echo "<tr>"; echo "<td>".$region."</td>"; foreach ($date_array as $date) { echo '<td><input type="text" name='.$region."-value1_".$date.'><input type="text" name='.$region."-value2_".$date.'></td>'; } echo "</tr>"; } ?> </table> <input type="submit" name="submit">And the next part:
if (isset($_POST['submit'])) { foreach ($_POST as $k=>$v) { if ($k != "submit") // use even and odd count to differentiate TRP and CPP { // split the form input on _ $input = explode("_", $k); echo "<BR>Region: " . $input[0]; echo "<BR>Date: " . $input[1]; echo "<BR>Value: " . $v; } echo "<br/>"; } }So basically, in this example it outputs 12 times:
Region: NYC-value1 Date: 01/01/2012 Value: 500 Region: NYC-value2 Date: 01/01/2012 Value: 5 Region: NYC-value1 Date: 01/08/2012 Value: 600
I want to catch the value1 and value2 while the loop is running, but as it stands it loops through both of them before going onto the next date/region. My idea, as I put in comments, was to have a counter of even and odd numbers and simply tell if it was doing value1 or value2 based on that.
Is this a good idea or am I missing something fundamentally simpler?
