What is NOT working? Can you tell us any error that is occurring or any similar symptoms? My php code that don't work true: doesn't make people understand your problem adequately –  Shades88 Jul 22 '12 at 18:47
 
Are you sure you want the dates serialized in one column? Sounds like a database design issue. –  PeeHaa Jul 22 '12 at 18:47

I don't recommend this format data to store it in a database, but if you want to save in this way you must do a few changes:

Change your form:

you are working with non fixed number of fields, you can use an structure like:

<input name="static[NUMBER]" value="XXX">
<input name="data_NUMBER[1]" value="YYYYY">

and in php you can get the info of the static=NUMBER as $_POST["data_".NUMBER]

<form method="post">
<input name="static[1]" value="12">
<input name="data_1[0]" value="1111111111">
<input name="data_1[1]" value="2222222222">
<input name="data_1[2]" value="3333333333">
<input name="data_1[3]" value="4444444444">

<input name="static[2]" value="34">
<input name="data_2[0]" value="5555555555">
<input name="data_2[1]" value="6666666666">
<input name="data_2[2]" value="7777777777">

<input name="static[3]" value="56">
<input name="data_3[0]" value="8888888888">
<input name="data_3[1]" value="9999999999">

<input type="submit">
</form>

and change the php:

foreach($static as $idx=>$val){
    $data_=$_POST["data_".$idx];
    $data[] = array(
        'static' => $static[$idx],
        'data_1' => json_encode($data_)             
    );
}
