I am sure that you did implode somewhere to store comma-separated values. Can you tell me if you are doing explode anywhere? If  you are not doing implode while storing then I would like to know how you are able to store comma-separated values in the database.

Hi,

I have the same problem.

 

I explode the values and set them into the variable

 

$this->fields_value['especialidad[]'] = explode(',',$obj->especialidad);

 

but take only the firts value.

 

If I change the configuration, without use the class 'chosen', work perfectly, but use the chosen class is important because of the kind of client who will manipulate the system.

Why happen this?

 

Can anybody help me?

 

Thanks in advance!

I have answered this question on stackoverflow. Here I am providing the same answer which I think should solve the issue you have faced:

 

I found a solution to the problem with Prestashop multiple select form helper issue.

 

In order for the select box to work properly there are the following requirements:

 

 1. Input name should have '[]'. For example: manufacturer_ids[]

 2. $fields_value array should have this element with the same name: manufacturer_ids[] not manufacturer_ids.

 3. The value of the $fields_value array's corresponding item should have selected values as array. For example: 

 

    $fields_value['manufacturer_ids[]'] = array("120", "145");

 

 

I save the submitted values as sarialized string in Database, so I am handling it this way:

 

        $selectedManufacturers = @unserialize($manufacturerIdsTakenFromDb);
        if ($selectedManufacturers === false && $selectedManufacturers !== 'b:0;') {
            $selectedManufacturers = array();
        }        
        $fields_value['manufacturer_ids[]'] = $selectedManufacturers;

 

And my code in form definition looks like this:

 

    array(
        'type' => 'select',
        'label' => $this->l('Manufacturers'),
        'name' => 'manufacturer_ids[]',
        'multiple' => true,
        'options' => array(
            'query' => array(
                array('key' => '1', 'name' => 'Apple'),
                array('key' => '2', 'name' => 'Samsung'),
                array('key' => '3', 'name' => 'HTC'),
            ),
            'id' => 'key',
            'name' => 'name'
        )
    ),

 

If your code does satisfy all these and it still does not work, please let me know, I will be happy to assist you to fix it.
