Sending multi-dimensional array by POST

Question

I am sending a multidimensional array by POST using the following:

<form action="fixtures.php" method="POST">

    <input type="hidden" name="day" value="<?= $day ?>">
    <input type="hidden" name="month" value="<?= $month ?>">
    <input type="hidden" name="year" value="<?= $year ?>">
    <input type="hidden" name="league" value="<?= $league ?>">
    <input type="hidden" name="addFixtures" value="1">

    <?php

    for($i = 0; $i < count($fixtures); $i++){

         $team_a_name = $fixtures[$i]['team-a-name'];
         $team_b_name = $fixtures[$i]['team-b-name'];
         $fixtDate = $fixtures[$i]['Date'];

         echo "<input type='hidden' name=\"fixtures[$i]['team-a-name']\" value='$team_a_name'>";
         echo "<input type='hidden' name=\"fixtures[$i]['team-b-name']\" value='$team_b_name'>";
         echo "<input type='hidden' name=\"fixtures[$i]['date']\" value='$fixtDate'>";

    }

    ?>

    <input type="submit" value="Add Fixtures">

</form>

However, when I try to access the values stored inside $_POST['fixtures'], using the following:

if(isset($_POST['addFixtures'])){

    print_r($_POST['fixtures'][0]);
    echo "<br><br>";
    print($_POST['fixtures'][0]['date']);

    exit;

}

I get this output:

Array ( ['team-a-name'] => TEAM A ['team-b-name'] => TEAM B ['date'] => 5-4-2016 )

Notice: Undefined index: date in /Applications/XAMPP/xamppfiles/htdocs/soccerdome/fixtures.php on line 33

The same notice appears if I try to access 'team-a-name' or 'team-b-name'. Why can't I access these values, when print_r on $_POST['fixtures'][0] clearly shows that they are in the array!

EDIT

When printing out $_POST[], I get:

    Array
(
    [day] => 5
    [month] => 4
    [year] => 2016
    [league] => prem
    [addFixtures] => 1
    [fixtures] => Array
        (
            [0] => Array
                (
                    ['team-a-name'] => TEAM A
                    ['team-b-name'] => TEAM B
                    ['date'] => 5-4-2016
                )

            [1] => Array
                (
                    ['team-a-name'] => TEAM C
                    ['team-b-name'] => TEAM D
                    ['date'] => 5-4-2016
                )

            [2] => Array
                (
                    ['team-a-name'] => TEAM A
                    ['team-b-name'] => TEAM D
                    ['date'] => 12-4-2016
                )

            [3] => Array
                (
                    ['team-a-name'] => TEAM B
                    ['team-b-name'] => TEAM C
                    ['date'] => 12-4-2016
                )

            [4] => Array
                (
                    ['team-a-name'] => TEAM A
                    ['team-b-name'] => TEAM C
                    ['date'] => 19-4-2016
                )

            [5] => Array
                (
                    ['team-a-name'] => TEAM D
                    ['team-b-name'] => TEAM B
                    ['date'] => 19-4-2016
                )

        )

)

For some reason it is now working! I have no idea how, just be refreshing the page multiple times, the error message disappeared and the value inside POST was printed!

Here you are using capital 'D' in your date `$fixtDate = $fixtures[$i]['Date'];` and using 'date' in input name — Manjeet Barnala, Apr 05 '16 at 12:35
Try removing the single quote from the key name in form input. Change name=\"fixtures[$i]['team-a-name']\" to name=\"fixtures[$i][team-a-name]\" — Ghulam Ali, Apr 05 '16 at 12:36
You mean how to use in php? Just like what you were doing before echo $_POST['fixtures'][0]['date']; or echo $_POST['fixtures'][0]['team-a-name']; — Ghulam Ali, Apr 05 '16 at 12:40
single quotes are part of array name, so either remove them or use `echo $_POST['fixtures'][0]['\'date\'']`. — mitkosoft, Apr 05 '16 at 12:40
Check this link you may get some idea. http://stackoverflow.com/a/2433843/4912315 — Abdullah Ahamed, Apr 05 '16 at 12:45
@PraveenKumar I have tried removing the quotes and the same error is displayed — Sam, Apr 05 '16 at 12:58

Easiest way to traverse the post data is using foreach. You can do this as following:

if(isset($_POST['addFixtures']))
{
    foreach($_POST['fixtures'] as $key=>$value)
    {
      echo "<br><br>";
      print($value['date']);
    }
}
exit;

Since you don't have any special characters in date, it is better to give without a ':

 echo "<input type='hidden' name=\"fixtures[$i]['team-a-name']\" value='$team_a_name'>";
 echo "<input type='hidden' name=\"fixtures[$i]['team-b-name']\" value='$team_b_name'>";
 echo "<input type='hidden' name=\"fixtures[$i][date]\" value='$fixtDate'>";

Or change it to:

 echo "<input type='hidden' name=\"fixtures[$i][team-a-name]\" value='$team_a_name'>";
 echo "<input type='hidden' name=\"fixtures[$i][team-b-name]\" value='$team_b_name'>";
 echo "<input type='hidden' name=\"fixtures[$i][date]\" value='$fixtDate'>";

Always use var_dump($_POST) or print_r($_POST) to check what's happening in reality. :)

I have put the output when using `print_r($_POST)` in my original question, but this code I have tried and it doesnt work – Sam Apr 05 '16 at 13:06

Saying as I tried removing the quotes last, I'll mark your answer as the correct answer – Sam Apr 05 '16 at 13:17

print_r the whole post array.i.e.print_r($_POST).Then you will have the exact keys and values assigned and will be successful in displaying the array.
