Php$数据问题，html表单

输入到具有名称的HTML元素中的数据

应用程序[字符名称]

会在

$\u POST['application']['character\u name']

在PHP中

将同样的逻辑应用于您拥有的每个字段
 我假设您有这样的表单字段（特别是
name
属性）：

你能出示你的表格吗？你不能像那样访问变量。试试
$character=$\u POST['application']['character\u name']等。
应用程序[字符名称]
是字符串吗？（应用程序是一个数组，字符_name是数组中的一个元素）如果是，请去掉它周围的'。
<?php
    $character = $_POST['application[character_name]'];
    $realm = $_POST['application[character_realm]'];
    $class = $_POST['application[character_class_id]'];
    $dependent = $_POST['application[answered_questions_attributes][0][id]'];
    $spec = $_POST['application[answered_questions_attributes][1][id]'];
    $history = $_POST['application[answered_questions_attributes][2][id]'];
    $why = $_POST['application[answered_questions_attributes][3][id]'];
    $about = $_POST['application[answered_questions_attributes][4][id]'];
    $ui = $_POST['application[answered_questions_attributes][5][id]'];
    $combatlog = $_POST['application[answered_questions_attributes][6][id]'];
    $contact = $_POST['application[answered_questions_attributes][7][id]'];
    $add = $_POST['application[answered_questions_attributes][8][id]'];

    //the data
