MYSQL&；PHP将数据发送到数据库并将数组包含到行中

你好，我希望你今天很好

我有一个表单，它使用$\u会话存储表单末尾的数据，我要求表单提交到数据库

在我的表单中，有一个选项允许用户根据其子项添加新的输入

例如，如果他们的用户有一个子用户，他们按下一个按钮，jQuery添加一个输入字段，然后该输入将数据输出到会话中

$_会议[“儿童”]

这是数组数据（其中包含一些示例）

我的问题是，我现在正在将数据提交到数据库，我可以在一个SQL查询中将表单的所有其他实例（例如“first_name”“last_name”）发送到数据库，而不会出现任何问题：

$sql  = "INSERT INTO wills(";
$sql .= implode(", ",$in_fields);
$sql .= ") VALUES (";
$sql .= implode(", ",$in_values);
$sql .= ")";

首先，上面的SQL insert查询不会将儿童添加到数据库中，因为它会获取值“array”

我计划将数据以序列化格式存储到children字段中，以便查询

我在尝试将数组插入children字段时遇到了问题，但我成功地将它作为虚拟测试在没有任何变量的情况下运行

$sql  = "INSERT INTO wills(children) VALUES (bob john simon)";

上面的问题还在于，它将其添加到新的数据库行，而不是同一行

以下是完整的代码：

// sql fields and values
$in_fields = array();
$in_values = array();
$in_children = serialize($_SESSION['children']);

foreach($_SESSION as $key => $value) {
    if(!empty($value)) {
        $value = sql_escape($value);
        $key = explode("#",$key);
            $in_fields[] = "`{$key[0]}`";
            $in_values[] = "'{$value}'";
    }
}


if(!empty($in_fields)) {




    $sql  = "INSERT INTO wills(";
    $sql .= implode(", ",$in_fields);
    $sql .= ") VALUES (";
    $sql .= implode(", ",$in_values);
    $sql .= ")";



    executeSql($sql);

}

不确定您的问题是什么，但请注意，插入的字符串值必须用引号括起来：

INSERT INTO myTable (field1, field2) VALUES ('value1', 'value2')

---

使用单引号或双引号并不重要，但在您的情况下，最好使用单引号，因为php字符串使用双引号。

我的问题是，我无法获取子会话的数据（这是一个数组）要输入到我试图提交到的行中，您为什么要在foreach中迭代

$\u SESSION

？难道您不想在会话['children']中使用所有键/值吗？

INSERT INTO myTable (field1, field2) VALUES ('value1', 'value2')
