重力形式中动态填充的复选框错误

Question

我已将复选框动态添加到 Gravity 表单，但是当我 select 最后 2 个项目并单击提交时，我收到错误消息 "this field is required"。如果我 select 1st item or 2nd , 3rd 那么没有错误并且表单提交成功。

这是我的 php 代码。

add_filter( 'gform_pre_render_56', 'get_menu_options' );
add_filter( 'gform_pre_validation_56', 'get_menu_options' );
add_filter( 'gform_pre_submission_filter_56', 'get_menu_options' );

function get_menu_options($form){
/****get all beverages from post*****/
$beverages = array_filter( get_post_meta(get_the_ID(), 'wpcf-beverages', false) );

$form['fields'][22]->choices =  set_field_choices($beverages); 

return $form;

}

function set_field_choices($values){
    $field_choices = array();
    $isSelected = (count($values) == 1)?true:false;
    foreach ($values as $value) {
        $field_choices[] = array(
                'text'          => $value,
                'value'         => $value,
                'isSelected'    => $isSelected
            );
    }
    return $field_choices;
}

好的，我想出了问题。我们需要关注输入 id

add_filter( 'gform_pre_render_56', 'get_menu_options' );
add_filter( 'gform_pre_validation_56', 'get_menu_options' );
add_filter( 'gform_pre_submission_filter_56', 'get_menu_options' );
add_filter( 'gform_admin_pre_render_56', 'get_menu_options' );

function get_menu_options($form){

$buffetstations1 = array_filter( get_post_meta(get_the_ID(), 'wpcf-buffet-station-1', false) );

foreach ( $form[ 'fields' ] as $key => $field ) {

if( $field->id == 72 ){
         
if( count($buffetstations1) == 0 ){ 
unset ( $form['fields'][$key]); 
}
   $choices = array();
    $inputs = array();
    $field_id = $field->id;
    $input_id = 1;

foreach ( $buffetstations1 as $buffetstation1 ) {
//skipping index that are multiples of 10 (multiples of 10 create problems as the input IDs)

if ( $input_id % 10 == 0 ) {
  $input_id++;
}

$choices[] = array( 'value' => $buffetstation1, 'text' => $buffetstation1 );
$inputs[] = array( 'label' => $buffetstation1, 'id' => "{$field_id}.{$input_id}" );
$input_id++;
}
$field->choices = $choices;
$field->inputs = $inputs;
      
}

}

return $form;

}

Answer 2

也可以用'form_field_value_$parameter'过滤器设置。给定一个带有选项 'Red'、'Green'、'Blue'、'Yellow' 'Orange' 的复选框字段和允许动态填充的字段参数：'color'以下将选中蓝色和绿色复选框。

add_filter( 'gform_field_value_color', 'set_checkbox' ); 
function set_checkbox( $form ) {
    return 'Blue,Green'; 
}

我相信这是最近添加到重力形式中的。
