Update Options Inserting Array Incorrectly

I wrote a plugin that inserts a music playlist as an array of multiple associative arrays. For most people it seems to be working, but there are a few for which it inserts the correct array, but the data is coming back as capital “A’s.”

So, instead of this:

(
[default] => Array
(
[1] => Array
(
[artist] => Feist
[title] => My Moon My Man
[file] => http://www.tracyfu.com/projects/wordphonic/mp3s/01.mp3
[image] => http://www.tracyfu.com/projects/wordphonic/images/01.png
)

[2] => Array
(
[artist] => Lovage
[title] => Stroker Ace
[file] => http://www.tracyfu.com/projects/wordphonic/mp3s/02.mp3
[image] => http://www.tracyfu.com/projects/wordphonic/images/02.png
)

[3] => Array
(
[artist] => Led Zeppelin
[title] => Since I’ve Been Loving You
[file] => http://www.tracyfu.com/projects/wordphonic/mp3s/03.mp3
[image] => http://www.tracyfu.com/projects/wordphonic/images/03.png
)
)

)

It’s printing this:

(
[default] => Array
(
[1] => Array
(
[artist] => A
[title] => A
[file] => A
[image] => A
)

[2] => Array
(
[artist] => A
[title] => A
[file] => A
[image] => A
)

[3] => Array
(
[artist] => A
[title] => A
[file] => A
[image] => A
)
)

)

I can’t figure out for the life of me why… The data is coming from input fields that look like this:

<input type="text" name="ephonic_playlists[default][1][artist]" />

And, when I look in the DB the data is serialized correctly. The only thing I can think is that the array must read “Array(…)” and it’s only reading the first ‘A’, but I really don’t know…

Please help anyone?
