保存复选框组在窗口小部件Wordpress [英] Save Checkbox Group in Widgets Wordpress

问题描述

我无法使多个复选框工作，对我的生活有用。

其他一切正常，包括一个复选框，但我不知道如何做多个复选框。

我想要的是以下内容：

我有一个名为Team的自定义职位类型，它。我想做一个小部件的帖子在团队。我想要复选框输出Team中的所有帖子，其中最终用户可以选择显示谁。

我试着在数组中做，但是没有用。

我的单个复选框是这样的：

  public function widget（$ args，$ instance）{
 $ teammember = $ instance ['teammember'] ; 
} 
 
公共函数更新（$ new_instance，$ old_instance）{
 $ instance ['teammember'] = $ new_instance ['teammember']; 
 return $ instance; 
} 
 
 public function form（$ instance）{
 $ teammember = $ instance ['teammember']; 
？> 
< p> 
< input id =<？php echo $ this-> get_field_id（'teammember'）;？> name =<？php echo $ this-> get_field_name（'teammember'）;？> type =checkboxvalue =Name 1<？php checked（'1'，$ teammember）; > />名称1 
< input id =<？php echo $ this-> get_field_id（'teammember'）;？& name =<？php echo $ this-> get_field_name（'teammember'）;？> type =checkboxvalue =Name 2<？php checked（'1'，$ teammember）; > />名称2 
< / p> 
<？php}？> 
  

所以让我们说我有10个团队成员，我希望他们都在小部件中有一个复选框

解决方案。

在您的示例中，由于ID重复，输入将有W3C违规。这些名称会相互覆盖。

$ this-> get_field_name（'teammember'）;

 
 $ b 
 <？php 
 public function form（$ instance）{
 $ teammember = $ instance ['teammember']; 
？> 
< p> 
<？php 
 foreach（$ teammember as $ id => $ name）{
？ 
< input id =<？php echo $ this-> get_field_id（'teammember'）。$ id;？& name =<？php echo $ this-> get_field_name（'teammember'）;？> []type =checkboxvalue =<？php echo $ name;？& <？php checked（'1'，$ name）; > /> 
<？php 
} 
？> 
< / p> 
<？php 
} 
  

I cannot get multiple checkboxes to work, for the life of me!

Everything else works, including a single checkbox, but I don't know how to make multiple checkboxes.

What I want is the following:

I have a custom post type called Team, with all teammembers in it. I want to make a widget of the posts in Team. I want the checkbox to output all the posts in Team, where the enduser can select who to display.

I tried doing it in arrays, but that didn't work.

My single checkbox is like this:

public function widget( $args, $instance ) {
    $teammember = $instance['teammember'];
}

public function update( $new_instance, $old_instance ) {
    $instance['teammember'] = $new_instance['teammember'];
    return $instance;
}

public function form( $instance ) {
    $teammember = $instance['teammember'];
?>
<p>
    <input id="<?php echo $this->get_field_id('teammember'); ?>" name="<?php echo $this->get_field_name('teammember'); ?>" type="checkbox" value="Name 1" <?php checked( '1', $teammember ); ?>/> Name 1
    <input id="<?php echo $this->get_field_id('teammember'); ?>" name="<?php echo $this->get_field_name('teammember'); ?>" type="checkbox" value="Name 2" <?php checked( '1', $teammember ); ?>/> Name 2
</p>
<?php } ?>

So let's say I have 10 teammember, I want them all to have a checkbox in the widget where the enduser can select what teammember(s) to show.

How do I do that?

解决方案

In your example the inputs will have a W3C violation because of duplicate IDs. The names will override each other.

The $this->get_field_name('teammember'); will return the same results and override each other.

You need to achieve this as an array.

<?php
    public function form($instance) {
        $teammember = $instance['teammember'];
?>
<p>
    <?php
        foreach($teammember as $id => $name) {
    ?>
    <input id="<?php echo $this->get_field_id('teammember') . $id; ?>" name="<?php echo $this->get_field_name('teammember'); ?>[]" type="checkbox" value="<?php echo $name; ?>" <?php checked('1', $name); ?> />
    <?php
        }
    ?>
</p>
<?php
}
