cakephp将多个动态生成的下拉列表保存到数据库

Question

I have two drop down list and a textbox which can be dynamically added to my form with a button click as many times as possible, but my problem is the array of data from the dynamic form elements are not saving to my database table at a single submit. Below is the structure of the array on debug.

* current array *

array(
    'DrugTransaction' => array(
        'drug_type_id' => array(
            (int) 0 => '1',
            (int) 1 => '1'
        ),
        'drug_id' => array(
            (int) 0 => '1',
            (int) 1 => '2'
        ),
        'quantity' => array(
            (int) 0 => '15',
            (int) 1 => '21'
        )
    )
)

I want the array to look like the sample below

Array ( 
    [0] => Array ( 
        [drug_type_id] => 1 
        [drug_id] => 2 
        [quantity] => 14 

    )  
    [1] => Array ( 
        [drug_type_id] => 3 
        [drug_id] => 4 
        [quantity] => 100      
    )  
)

Answer 1

try this code

$result = array();

foreach($yourArray['DrugTransaction'] as $key => $subArray)
{

    foreach($subArray as $index => $value)
    {
        $result[$index][$key] = $value;
    }

}

edit: I think you also want id set to null, so you have to do something like:

foreach($result as $key => $value)
{
    $result[$key]['id'] = null;
    $result[$key]['supplydate'] = '2014-03-31';
}
