MYSQL & PHP 将数据发送到数据库并将数组包含到行中

Question

你好 Stack Overflow 我希望你今天一切都好；

我有一个表单，它使用 $_SESSION 在表单末尾存储数据，我需要它提交到数据库。

在我的表单中，有一个选项允许用户根据他们的孩子添加新的输入。

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

$_SESSION['孩子'];

这是数组数据（包含一些样本）；

Array ( [0] => Natural Chlid 1 [1] => Natural Chlid 2 [2] => Natural Chlid 3 ) 

我的问题是我现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 插入查询不会将 chlidren 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子字段中以供查询。

我在尝试将数组插入子字段时遇到问题，但我设法让它在没有任何变量的情况下作为虚拟测试工作。

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

上述问题也在于它将它添加到新的数据库行而不是同一行。

这里是完整的代码：

// 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);

}

print_r 的我的变量

不确定您的问题到底是什么，但请注意插入的字符串值必须用引号引起来：

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

使用单引号还是双引号都没有关系，但在您的情况下，您最好使用单引号，因为您的 php 字符串使用双引号。
