Select2不会创建名称属性 [英] Select2 does not create name attribute

问题描述

使用select2 jQuery PlugIn我创建了一个标签框。因此我使用了以下html表单代码：

With the select2 jQuery PlugIn I created a tag box. Therefore I used the following html form code:

<form action="someAction" method="post">
    <fieldset>
        <select id="tags" multiple="" name="tags">
            <option value="tag1">val1</option>
            <option value="tag2">val2</option>
            <option value="tag3">val3</option>
        </select>
        <button type="submit" class="btn">Submit</button>
    </fieldset>
</form>

Select2从中生成以下字段：

Select2 generates the following field from it:

<input type="text" class="select2-input" autocomplete="off" id="s2id_autogen1" style="width: 10px;">

这里的问题是 name 属性不见了。如果没有名称 $ _ POST 变量中获取输入字段的数据/文本>属性？如何管理？

The problem is here that the name attribute is missing. How can I get the data/text of the input field out of the $_POSTvariable in PHP if there is no name attribute? How can I manage this?

设置JS如下：

$(document).ready(function() {
$("#tags").select2({
    placeholder: "Insert tag",
    allowClear: true,
    minimumInputLength: 2,
    maximumSelectionSize: 1,
    minimumWidth: 200
});

}）;

推荐答案

这是一个老问题，但当前select2 4.xx版本的正确答案是将name属性设置为数组

it's an old question, but correct answer for current select2 4.x.x version is to set name attribute as array

<select id="tags" multiple="" name="tags[]">

然后你就可以获得带有$ _POST的数组：

and then you can get array with $_POST like that:

$_POST['tags']
