I want insert on a row of database table, following value with following php code(foreach) but after insert get following error, what do i do?

Values:

<div class="column">
    <input type="text" name="start_date[1][]" value="1111">
    <input type="text" name="end_date[1][]" value="1111">
    <input type="text" name="price_change[1][]" value="1111">
</div>
<div class="column">
    <input type="text" name="start_date[2][]" value="2222">
    <input type="text" name="end_date[2][]" value="2222">
    <input type="text" name="price_change[2][]" value="2222">
</div>
<div class="column">

Php code:

    $residence_ups_input = $this->input->post('start_date');
    $residence_upe_input = $this->input->post('end_date');
    $residence_upc_input = $this->input->post('price_change');
    var_dump($residence_ups_input); // output this is: nobool(false)
    $residence_p = array();
    foreach ($residence_ups_input as $idx => $name) { //line 134        
        $residence_p[] = array(
            'start_date' => $residence_ups_input[$idx],
            'end_date' => $residence_upe_input[$idx],
            'price_change' => $residence_upc_input[$idx]
        );
    }
    ;
    $data = array(
        //'name' => $this -> input -> post('name'),
        'residence_p' => json_encode($residence_p)
    );
    $this->db->insert('tour_foreign', $data);

    Change all columns:

    <div class="column">
    <input type="text" name="start_date[1][]" value="1111">
    <input type="text" name="end_date[1][]" value="1111">
    <input type="text" name="price_change[1][]" value="1111">
</div>
....

    to:

    <form method="post">
<div class="column">
    <input type="text" name="start_date[]" value="1111">
    <input type="text" name="end_date[]" value="1111">
    <input type="text" name="price_change[]" value="1111">
</div>
....

</form>
