WordPress重力形式获取列表值 [英] Wordpress Gravity Forms get List values

问题描述

有人可以指导我如何从包含列表字段的已提交表单中提取值吗？

Can somebody point me in the direction on how to extract values from submitted forms containing list fields?

我正在尝试使用以下方法创建前端发布表单重力形式，然后将提交的值分配给使用高级自定义字段创建的自定义字段。

I'm trying to create a front-end posting form using Gravity Forms, and then having the submitted values be assigned to custom fields made with Advanced Custom Fields.

对于普通字段，您可以使用以下方法执行此操作：

For normal fields, you can do this with the following:

add_action("gform_after_submission_1", "acf_submission", 10, 2);

function acf_submission($entry, $form)
{
   $post_id = $entry["post_id"];
   update_field('field_###', $entry['#'], $post_id ); 
   update_field('field_###', $entry['#'], $post_id ); 
   update_field('field_###', $entry['#'], $post_id );  
}

其中field _ ###是ACF自定义字段键，entry ['＃ ']是重力表单字段ID，$ post_id是要更新/存储值的帖子的ID。

Where field_### is the ACF custom field key, entry['#'] is the Gravity Forms field ID, and $post_id is the id of the post you want to update/store values to.

使用条目['＃']对于普通字段（文本，段落等）非常有用，但是列表（重复）字段的存储方式有所不同。在数据库中，该值看起来像这样（对于具有3个字段（列）的列表字段，对于单击添加按钮以添加列表字段的其他实例的人：

Using entry['#'] works great with normal fields (text, paragraph, etc.), but list (repeater) fields are stored a bit differently. In the DB, the value looks like this (for a list field that has 3 fields (columns), and for somebody who clicked the add button to add an additional instance of the list field:

a:2:{i:0;a:3:{s:4:"Column 1 Name";s:7:"value input";s:6:"Column 2 Name";s:34:"value input";s:11:"Column 3 Name";s:24:"value input";}i:1;a:3:{s:4:"Column 1 Name";s:11:"value input";s:6:"Column 2 Name";s:19:"value input";s:11:"Column 3 Name";s:22:"value input";}}

我不知道如何提取这些值并将其分配给ACF字段我尝试了entry ['＃。＃']，就像您对地址等字段所做的那样，但这没有用。

I can't figure out how to extract those values and assign them to ACF fields. I tried entry['#.#'] as you would do for fields like address, but that didn't work.

推荐答案

这是一个序列化数组，因此您可以使用php函数unserialize提取值。

This is a serialized array so you can use the php function unserialize to extract the values.

$array_values = unserialize($entry['#']);  
print_r($array_values); //see what your values are.

现在您有了自己的值，就可以在新的$ array_values数组中访问它们。
从序列化数组中获取一个值在PHP中

Now that you have your values you can access them in your new $array_values array. Getting one value out of a serialized array in PHP
