Question

// Models/Tables with HABTM:
companies, sectors, companies_sectors

// Controller
$sectors = $this->Sector->find('list', array('fields'=>array('Sector.id', 'Sector.sector')));

// View
echo $this->Form->input('Sector.id', array(
    'multiple' => 'checkbox',
    'options' => $sectors,
));

// Posted 
$this->request->data = array(
'Company' => array(
    'id' => '177',
    'company_name' => 'Testing Co',
),
'Sector' => array(
    'id' => array(
        (int) 0 => '2',
        (int) 1 => '3'
    )
));

// Controller
if ($this->request->is('post')) {

    // This saves the data into the 'companies' table just fine - but that's it
    $this->Company->save($this->request->data);

    // Tried this
    $this->Company->Sector->save($this->request->data);

    /* Get this error
     Error: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'Array' in 'field list'
     SQL Query: UPDATE `h_dev`.`sectors` SET `id` = Array WHERE `h_dev`.`sectors`.`id` = '2' 
    */

    // Tried this - does nothing
    foreach ($this->request->data['Sector']['id'] as $id)
    {
        // made sure $this->Company->id is set from previous save()
        $this->Company->Sector->create();
        $this->Company->Sector->save(array('company_id'=>$this->Company->id, 'sector_id'=>$id));
    }
}

如何将此请求＆gt;数据正确保存到所有HABTM表中？

StackOverflow要求我提供更多细节，即使我认为我已经足够清楚了。所以这只是填充文本。

我想我明白了！ $save = array(); foreach ($this->request->data['Sector']['id'] as $id) { $save[] = array('Company'=>array('id'=>$this->Company->id), 'Sector'=>array('id'=>$id)); } $this->Company->Sector->saveAll($save); 除非有人知道更好，否则我认为这会有效。

Answer 1

尝试使用此方法保存数据$ this-＆gt; Model-＆gt; saveAssociated（$ data）; CakePHP Model saveAssociated

Answer 2

您是否在模型中正确设置了关系？您需要确保Company和Sectors都有HABTM。还要确保HABTM的数据库表名称正确：companies_sectors

CakePHP - 保存HABTM
