php – jquery serializeArray表单中的JSON multiselect

作者:互联网

我有一个带有多选内部的表单.提交我有这个功能:

$( "#addTrainForm" ).submit(function( event ) {
    var dataString = $(this).serializeArray();
    console.log(dataString);
    event.preventDefault();
    $.ajax({  
        type: "POST",  
        url: "/index.php/trainings/insertTraining",
        data: dataString,
        dataType: 'json',
        success: function(data) {  
            $("div#addModal").hide();
            location.reload();
        }  
    });
    return false;
});

现在,您可以在其中看到控制台日志,我得到以下内容:

0: Object
name: "date"
value: "14/10/2013 16:22:46"
__proto__: Object
1: Object
name: "pool"
value: "1"
__proto__: Object
2: Object
name: "repeat_0"
value: "1"
__proto__: Object
3: Object
name: "distance_0"
value: "1"
__proto__: Object
4: Object
name: "style_0"
value: "1"
__proto__: Object
5: Object
name: "change_0"
value: "1"
__proto__: Object
6: Object
name: "time_0"
value: "1"
__proto__: Object
7: Object
name: "options_0"
value: "1"
__proto__: Object
8: Object
name: "options_0"
value: "2"
__proto__: Object
9: Object
name: "repeat_1"
value: "2"
__proto__: Object
10: Object
name: "distance_1"
value: "2"
__proto__: Object
11: Object
name: "style_1"
value: "1"
__proto__: Object
12: Object
name: "change_1"
value: "2"
__proto__: Object
13: Object
name: "time_1"
value: "2"
__proto__: Object
14: Object
name: "options_1"
value: "4"
__proto__: Object
15: Object
name: "options_1"
value: "5"
__proto__: Object
16: Object
name: "options_1"
value: "6"

您可以在其中看到options_0和options_1具有多个值.

现在在被调用的php函数中,我读取了所有的帖子数据并将其写入文件:

public function insertTraining(){
    $data=$this->input->post();
    $this->baselib->logIt(print_R($data,true));
}

在那里我的options_0和options_1只有最后一个值可用.我期待更多的值或一个逗号字符串或其他东西.这是我在文本文件上的登录情况:

Array
(
    [date] => 14/10/2013 16:22:46
    [pool] => 1
    [repeat_0] => 1
    [distance_0] => 1
    [style_0] => 1
    [change_0] => 1
    [time_0] => 1
    [options_0] => 2
    [repeat_1] => 2
    [distance_1] => 2
    [style_1] => 1
    [change_1] => 2
    [time_1] => 2
    [options_1] => 6
)

如何将options_0和options_1的所有值都添加到我的php脚本中?有没有更好的方法来使用我已经存在的函数(比如可选参数?)或者我是否必须运行循环arround所有值并找到选项值并将它们放入数组中然后使用json将其发送到PHP?

希望我设法解释自己,
谢谢,

解决方法:

找到了解决方案.问题既不是jquery也不是JSON,它只是在HTML中.你在哪里:

<select multiple id="..." name="foo">

你必须使用foo [],这将成为jquery方面的一个值数组,当你将它JSON到PHP时它会保持原样:)
所以上面的例子变成了:

<select multiple id="..." name="foo[]">
