将复选框值存储在数组中

Question

I have a set of 3 checkboxes that ask the user for input. They are constructed like this:

<span class="playback-format-checkbox-holder">
    <span><b>Playback Format</span><br />
        <label for="dvd">
          <input type="checkbox" name="playback_format[]" value="dvd"  id="dvd" />
        DVD
        </label>
        <label for="bluray">
          <input type="checkbox" name="playback_format[]" value="bluray"  id="bluray" />
        Bluray
        </label>
        <label for="3d">
          <input type="checkbox" name="playback_format[]" value="3d" id="3d"  />
        3D
        </label>
</span>

and I am posting the results like so

<?php
   $new = array();

   $playback_formats = $_POST['playback_format'];

   if ( isset($playback_formats) ) {
     $new['playback_format'] = $playback_formats;           
   }
?>

If I select two values, only one is returned. For example, if i select bluray and 3d, the array only stores bluray. If I check dvd and 3d only dvd is stored. So only the first selection is being stored in the playback_format array.

What have I done wrong?

If I check one checkbox in each row it returns the correct values. the playback_format[] array is not storing as an array. Why?

If I check two boxes in the first row, and leave the second row blank the first row gets the first selection and the second row gets the second.

I have no idea what is going on. This seems like it shouldn't be this difficult...

This is when I check DVD and Bluray on the first set of checkboxes, and leave the second set of checkboxes blank.

Array ( [0] => Array ( [0] => Array ( [select] =>
Testing Title #1

[url] =>
Description #1

[playback_format] => Array ( [0] => bluray ) ) [1] => Array ( [select] =>
Testing Title #2

[url] =>
Description #2

[playback_format] => Array ( [0] => dvd ) ) ) )
testing a new list

As you can see, its not storing in the correct array. The second checkbox value has been stored in the second array for whatever reason, and not in the first row playback_format array.

This is driving me crazy.

您只想尝试，我认为那会更好

foreach ($playback_format as $3d){}
