CakePHP，为多选框设置复杂/多重查找条件

Question

I have a multi-select box named Manufacturer Name that is displaying correctly, even clickable for multi search. When I run the search I am not getting any results from my database using the complex find conditions I set. I've tried to use Complex-Find-Conditions from the bakery, and other various websites but no avail.

//This my index.ctp
<?=$form->create('ManufacturersProductsLine', array('action'=>'index'));?>
    <table width="100%" border="0" cellspacing="0" cellpadding="0">
        <tr>
            <td>
                <?=$f->label('ManufacturersProductsLine.manufacturer_id', 'Manufacturer Name:'); ?>
                <?=$f->select('ManufacturersProductsLine.manufacturer_id', $manufacturers, null, array('multiple'=>'multiple', 'style'=>'height:100px;'))?>
            </td>
            <td>
                <?=$f->label('ManufacturersProductsLine.name', 'Product Name:'); ?>
                <?=$f->text('ManufacturersProductsLine.name', array('style'=>'width:140px;'));?>
            </td>
            <td>
                <label></label>
                <input name="Search" class="blue" type="submit" value="Search Product Lines" />
            </td>
        </tr>
    </table>

Commented out is things I have tried in my controller for setting the multiple find conditions.

//This is my manufacturers_products_lines_controller.php
function index() {
    $conditions = array();
    if (!empty($this->data)) {
        $data = $this->data;

        $conditions[] = "(LOWER(ManufacturersProductsLine.manufacturer_id) LIKE '%{$data['ManufacturersProductsLine']['manufacturer_id']}%')";
        //$conditions = array("ManufacturersProductsLine.name" => array("Akuret", "Bridgestone", "American Radials") );

        debug($this->data);
    }
    $this->Manufacturer->recursive = 1;
    $this->set('manufacturersproductslines', $manufacturersproductslines = $this->paginate('ManufacturersProductsLine', $conditions));
    $Manufacturer = getModel('Manufacturer');
    $this->set('manufacturers', $Manufacturer->find('list'));
    //$this->ManufacturersProductsLine->recursive = 0;
    //$this->Post->find('all', array('conditions' => array('ManufacturersProductsLine.manufacturer_id' =>array(0,1,2,3,4,5,6,7,8,9,10,11,12,13))));

}

When I debug and search I am getting the following.

Array
(
[ManufacturersProductsLine] => Array
    (
        [manufacturer_id] => Array
            (
                [0] => 1
                [1] => 2
            )

        [name] => 
    )
)

Answer 1

try changing the query condition to this

$conditions[] = "ManufacturersProductsLine.manufacturer_id IN (" . implode( ',', $data['ManufacturersProductsLine']['manufacturer_id'] . ")";
