[英]Setting a default value on settings form return null in Octobercms
I create a little plugin for the OctoberCMS but now dealing with a problem of setting a default value for a settings form. 我为OctoberCMS创建了一个小插件,但现在遇到了为设置表单设置默认值的问题。
I used database storage for my plugin settings (Backend -> Settings tab -> My Plugin tab) which works , quite good, except I cannot set default values. 我将数据库存储用于我的插件设置(“后端”->“设置”选项卡->“我的插件”选项卡),效果很好,只是无法设置默认值。
I have a fields.yaml
with this content: 我有一个具有以下内容的fields.yaml
:
tabs:
fields:
reviews_border_color:
label: 'Field1'
span: left
tab: 'review_sticker'
required: 1
type: text
default: '#F2F2F2'
rating_star_size:
label: 'Field2'
span: left
tab: 'review_sticker'
required: 1
type: number
default: 14
I retrieve the settings in my components like this: 我像这样检索组件中的设置:
<?php namespace Codedge\TestPlugin\Components;
use Cms\Classes\ComponentBase;
use Codedge\TestPlugin\Models\Settings;
class TestComponent extends ComponentBase
{
public $starSize;
public $borderColor;
public function componentDetails()
{
return [
'name' => 'Test Component',
'description' => '...'
];
}
public function defineProperties()
{
return [];
}
public function init()
{
$this->starSize = Settings::get('rating_star_size'); // not giving a default value when empty, default is 14
$this->borderColor = Settings::get('reviews_border_color'); // not giving a default value when empty, default is '#F2F2F2'
}
}
I also tried to set the default value, as second param in the get()
method as suggested in the OctoberCMS docs : 我还尝试设置默认值,作为OctoberCMS文档中建议的get()
方法中的第二个参数:
public function init()
{
$this->starSize = Settings::get('rating_star_size', 14); // returns null
$this->borderColor = Settings::get('reviews_border_color', '#F2F2F2'); // returns null
}
So any suggestions how I can reliably set a default value if none is specified/entered in to the settings form field? 因此,如果没有在设置表单字段中指定/输入任何默认值,那么我如何才能可靠地设置默认值呢?
Update: 更新:
After some digging aroung I found the explanation in the method getSettingsValue()
in system/behaviors/SettingsModel.php
经过一番挖掘后,我在system/behaviors/SettingsModel.php
中的getSettingsValue()
方法中找到了解释。
/**
* Get a single setting value, or return a default value
*/
public function getSettingsValue($key, $default = null)
{
if (array_key_exists($key, $this->fieldValues)) {
return $this->fieldValues[$key];
}
return $default;
}
As my field exists in $this->fieldValues
it returns it empty to me instead of returning the $default
value. 由于我的字段存在于$this->fieldValues
因此它对我返回空值,而不是返回$default
值。
So what I thought, returning the default value if the field value is empty, is not covered. 因此,我认为,如果字段值为空,则返回默认值的问题并未涵盖。
Any suggestions? 有什么建议么?
Why don't you use initSettingsData
function, you can use it like this: 为什么不使用initSettingsData
函数,您可以像这样使用它:
class Settings extends Model
{
public $implement = ['System.Behaviors.SettingsModel'];
// A unique code
public $settingsCode = 'my-settings';
// Reference to field configuration
public $settingsFields = 'fields.yaml';
public function initSettingsData()
{
$this->admin_email = 'some@email.com';
$this->admin_name = 'Walid Ammar';
$this->other_settings = 'other value';
}
}
After consulting with the OctoberCMS team on Github, the current behaviour is intented/not a bug - see https://github.com/octobercms/october/issues/2094 . 与Github上的OctoberCMS团队协商后,当前的行为是有意的/不是错误-请参阅https://github.com/octobercms/october/issues/2094 。 There could be considerations to change this behaviour, but this is another story. 可能会考虑更改此行为,但这是另一回事了。
