我正在尝试将问题选项输入保存到数据库中的表中。但是，我只能将最后一个问题输入保存到 db 中，而不能保存之前的其他问题。

我目前正在使用 foreach 循环根据问题结构表输出文本字段输入。

我真的不知道如何用语言解释，让我给你看我的代码。我是这个领域的新手，希望你们理解并帮助我:)

从您的代码中，我认为您将创建一组输入标签，为每个问题使用相同的名称，所以我认为这就是您唯一得到的原因。您可以尝试将其声明为数组，然后在保存到数据库时尝试循环。

从你的问题：''with foreach loop to MYSQL''

如果你想使用 foreach 循环，为什么不在数组中做呢

<input type="text" name="salaries[]" >
<input type="text" name="salaries[]" >

提交时

像这样循环你的文本字段

$salaries=$_POST['salaries'];

foreach ($salaries as $key => $value){
echo $value;
}

如果您不确定如何在数组中插入表单，我建议您使用准备语句

//$dbc is your database connection
mysqli_autocommit($dbc,false);  
if($stmt=$dbc->prepare("INSERT INTO question_table ('question_detail') VALUES ('?')")){

foreach ($salaries as $key => $value){

    $stmt->bind_param('s',$value);
    $stmt->execute();
    if(!$stmt){//if statement problem , prevent commit
        echo 'insertion failed , roll back all query';
        exit(); 
    }//end of smtp error

}//end of foreach
mysqli_commit($dbc);
