【中文标题】创建PHP动态多字段的JSON格式【英文标题】：Create JSON format of PHP dynamic multiple fields 【发布时间】：2021-01-25 10:21:57 【问题描述】：我需要创建从 php 表单接收到的数据的特定 JSON 格式。如果我可以制作正确的数组，那么我可以将其转换为 JSON，但找不到如何...我的表单有多个字段，它们获取数据并转换为这样的数组
Array
(
[user_id] =>
[title2] => Billing
[sub_title2] => to
[emails2] => abc@gmail.com
[sub_title3] => cc
[emails3] => xyz@gmail.com
[sub_title4] => for
[emails4] => john@gmail.com
[title5] => Free
[sub_title5] => cc
[emails5] => abc@gmail.com
[sub_title6] => adf
[emails6] => ben@gmail.com,ten@gmail.com
)
这是获取数据的代码
$(document).on("click", "#add_section", function (e)
i++;
k++;
var html1 ='<div id="email_section'+k+'" style="margin-top: 20px" class="form-group row">';
Html1 += '<div class="col-lg-12">';
Html1 += '<div class="col-lg-9">';
Html1 += '<label class="control-label col-lg-3">Add Section'+i+'<span style="color:red;"> *</span></label>';
Html1 += '<div class="col-lg-9">';
Html1 += '<input class=" form-control" id="title'+i+'[]" name="title'+i+'" type="text" placeholder="Sales" />';
Html1 += '</div>';
Html1 += '</div>';
Html1 += '</div>';
Html1 += '<div class="col-lg-12">';
Html1 += '<div class="col-lg-9">';
Html1 += '<label class="control-label col-lg-3"></label>';
Html1 += '<div class="col-lg-2">';
Html1 += '<input class=" form-control" id="sub_title'+i+'[]" name="sub_title'+i+'" type="text" placeholder="to" />';
Html1 += '</div>';
Html1 += '<div class="col-lg-7">';
Html1 += '<input class=" form-control" id="emails'+i+'[]" name="emails'+i+'" placeholder="abc@gmail.com" />';
Html1 += '</div>';
Html1 += '</div>';
Html1 += '<div class="col-lg-2">';
Html1 += '<span class="btn btn-primary add_email_row" id="'+k+'">Add</span>';
Html1 += '</div>';
Html1 += '</div>';
$('.modal-body').append(Html1);
);
$(document).on("click", ".add_email_row", function (e)
i++;
k++;
var section = $(this).attr("id");
var Html = '<div id="row'+i+'" class="row">';
Html += '<div class="col-sm-12">';
Html += '<div class="col-sm-2" style="margin-left: 20px;"></div>';
Html += '<div class="col-sm-9">';
Html += '<div class="col-sm-2"><input class=" form-control" id="sub_title'+i+'[]" name="sub_title'+i+'" type="text" placeholder="to" /></div>';
Html += '<div class="col-sm-7"><input class=" form-control" id="emails'+i+'[]" name="emails'+i+'" type="text" placeholder="emails" /></div>';
Html += '<div class="col-sm-3"><a type="button" name="remove" id="'+i+'" class="btn btn-danger btn_remove">X</a></div>';
Html += '</div></div></div>';
$('#email_section'+section+'').append(Html);
);
我想要的JSON格式是
"billing":
"to":"abc@email.com",
"cc":"xyz@email.com",
"adf":"mail@email.com",
"from":""
,
"free":
"to":"abc@gmail.com,",
"cc":"xyz@email.com",
"adf":""

【问题讨论】：
【参考方案1】：如果可以更改表单，则将输入更改为数组。还要封装你的两个块并将它们保持在相同的增量逻辑中：
<script>
function addSection(i, k)
var Html1 =
'<div id="email_section'+k+'" style="margin-top: 20px" class="form-group row">' +
'<div class="col-lg-12">' +
'<div class="col-lg-9">' +
'<label class="control-label col-lg-3">Add Section'+i+'<span style="color:red;"> *</span></label>' +
'<div class="col-lg-9">' +
'<input class=" form-control" id="title'+i+'" name="title['+i+']" type="text" placeholder="Sales" />' +
'</div>' +
'</div>' +
'</div>' +
'<div class="col-lg-12">' +
'<div class="col-lg-9">' +
'<label class="control-label col-lg-3"></label>' +
'<div class="col-lg-2">' +
'<input class=" form-control" id="sub_title'+i+'" name="sub_title['+i+'][]" type="text" placeholder="to" />' +
'</div>' +
'<div class="col-lg-7">' +
'<input class=" form-control" id="emails'+i+'" name="emails['+i+'][]" placeholder="abc@gmail.com" />' +
'</div>' +
'</div>' +
'<div class="col-lg-2">' +
'<span class="btn btn-primary add_email_row" id="'+k+'">Add</span>' +
'</div>' +
'</div>';
$('.modal-body').append(Html1);
function addEmail(obj, i, k)
var section = obj.attr("id");
var Html =
'<div id="row'+i+'" class="row">' +
'<div class="col-sm-12">' +
'<div class="col-sm-2" style="margin-left: 20px;"></div>' +
'<div class="col-sm-9">' +
'<div class="col-sm-2"><input class=" form-control" id="sub_title'+i+'" name="sub_title['+i+'][]" type="text" placeholder="to" /></div>' +
'<div class="col-sm-7"><input class=" form-control" id="emails'+i+'" name="emails['+i+'][]" type="text" placeholder="emails" /></div>' +
'<div class="col-sm-3"><a type="button" name="remove" id="'+i+'" class="btn btn-danger btn_remove">X</a></div>' +
'</div>' +
'</div>' +
'</div>';
$('#email_section'+section).append(Html);
var i = 0;
var k = 0;
$(document).on("click", "#add_section,.add_email_row", function (e)
if($(this).hasClass('add_email_row'))
addEmail($(this), i, k);
else
i++;
k++;
addSection(i, k);
);
</script>
你应该留下：
Array
(
[title] => Array
(
[1] => Section 1
[2] => Section 2
)
[sub_title] => Array
(
[1] => Array
(
[0] => subtitle1
[1] => subtitle2
[2] => subtitle3
)
[2] => Array
(
[0] => subtitle1
)
)
[emails] => Array
(
[1] => Array
(
[0] => email1@example.com
[1] => email2@example.com
[2] => email3@example.com
)
[2] => Array
(
[0] => email1@example.com
)
)
)
从这里可以更容易地在 php 中获取您的数组：
$array = $_POST;
$new = [];
foreach($array['title'] as $k => $title)
$new[$title] = array_combine($array['sub_title'][$k], $array['emails'][$k]);
echo json_encode($new, JSON_PRETTY_PRINT);
这会给你：
"Section 1":
"subtitle1": "email1@example.com",
"subtitle2": "email2@example.com",
"subtitle3": "email3@example.com"
,
"Section 2":
"subtitle1": "email1@example.com"
