Prestashop在模块中设置了多个选择，并将其输入到输入中 [英] Prestashop set multiple select from the module and get them in the input

问题描述

我正在Prestashop中做一个小模块.在该模块中，我将multiselect与helperform一起使用.所以我的代码就是这样

I am doing a small module in Prestashop. In that module I have used multiselect with helperform. So my code is like this

array(
    'type' => 'select',
    'cols' => 8,
    'class' => 'chosen-product-selct selected_products ',
    'multiple' => true,
    'label' => $this->l('Selected Products'),
    'name' => 'selected_products[]',
    'options' => array(
        'query' => $product_query,
        'id' => 'id',
        'name' => 'product_name'
    ),
    'desc' => $this->l('Select products from products list.'),
),

在这里，我将这些选择的值保存到数据库中.但是，当我进行编辑时，在框中没有选择任何已保存的值.盒子是完全空的.

Here I am saving those multiselected values to the database. But when I am doing edit no saved values has been selected in the box. The box is totally empty.

为了获得结果，我正在这样做

for getting the result I am doing this

public function getConfigFieldsValues() {
    'selected_products[]'  => Tools::getValue('selected_products', Configuration::get('selected_products')),
}

它不显示已输入的值.有人可以告诉我如何解决此问题吗?任何帮助和建议将是非常可观的.谢谢

Its not showing the values that has been entered.So can someone tell me how to solve this issue? Any help and suggestions will be really appreciable. Thanks

推荐答案

我找到了Prestashop多重选择表单帮助程序问题的解决方案.

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

为了使选择框正常工作，需要满足以下要求:

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

1. 输入名称应为"[]".例如:maker_ids []
2. $ fields_value数组应具有相同名称的该元素:Manufacturer_ids []而不是Manufacturer_ids.

3. $ fields_value数组的相应项目的值应具有选定的值作为数组.例如:

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");

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

我将提交的值另存为可序列化的字符串在数据库中，因此我以这种方式处理它:

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;

我在表单定义中的代码如下:

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'
    )
),
