Question

我需要在相同的id上将动态文本框值插入到数据库表中，现在我可以只在不同的用户ID上插入值。

当我尝试将动态文本框值插入到id 1的数据库表中时，动态文本框值会转到不同的id，如2,3,4等等。并且还会变为id为1的零字段值。{ {3}}

这是我的html和javascript代码：

这是我的用于插入数据库的PHP代码

<?php
$username="root";
$password="sha12345";
$hostname="localhost";

$dbhandle = mysql_connect($hostname,$username,$password) or die("Could not connect to database");

$select = mysql_select_db("sha", $dbhandle);


    if(isset($_POST['save']))
{
    $personname = $_POST['first_name1'];
    $fathername = $_POST['first_name2'];
    $mothernname = $_POST['first_name3'];


    mysql_query("INSERT INTO sha(Name_person,Name_father,Name_mother)   VALUES ('$personname','$fathername','$mothernname')");  



        if(!empty($_POST["save"])) {


        $itemCount = count($_POST["name1"]);
        $itemValues=0;
        $query = "INSERT INTO sha (no_members,name_members,age_members,relation_members,occupation_members) VALUES ";
        $queryValue = "";
        for($i=0;$i<$itemCount;$i++) {
            if(!empty($_POST["name1"][$i]) || !empty($_POST["name2"][$i]) || !empty($_POST["name3"][$i]) || !empty($_POST["name4"][$i]) || !empty($_POST["name5"][$i])) {
                $itemValues++;
                if($queryValue!="") {
                    $queryValue .= ",";
                }
                $queryValue .= "('" . $_POST["name1"][$i] . "', '" . $_POST["name2"][$i] . "', '" . $_POST["name3"][$i] . "', '" . $_POST["name4"][$i] . "', '" . $_POST["name5"][$i] . "')";
            }
        }
        $sql = $query.$queryValue;
        if($itemValues!=0) {
            $result = mysql_query($sql);
            if(!empty($result)) $message = "Added Successfully.";
        }

Answer 1

您可以在HTML中使用name="first_name[]"

等输入数组

<input type="text" name="first_name[]" id="fname1" placeholder="Enter name" value=""/>
<input type="text" name="first_name[]" id="fname2" placeholder="Enter name" value=""/>
<input type="text" name="first_name[]" id="fname3" placeholder="Enter name" value=""/>

然后在php中获取时，你可以写

print_r($_POST['first_name']);

这将包含数组

中的所有值

Answer 2

好的，以下是您可以遵循的步骤

创建表格用户

CREATE TABLE users(
   id INT NOT NULL AUTO_INCREMENT,
   Name_person VARCHAR(50) NOT NULL,
   Name_father VARCHAR(50) NOT NULL,
   Name_mother VARCHAR(50) NOT NULL,
   PRIMARY KEY ( id )
);

创建表family_members

CREATE TABLE family_members(
   id INT NOT NULL AUTO_INCREMENT,
   user_id INT NOT NULL,
   no_members TINYINT(2) NOT NULL DEFAULT 1,
   name_members VARCHAR(50) NOT NULL,
   age_members VARCHAR(50) NOT NULL,
   relation_members VARCHAR(50) NOT NULL,
   occupation_members VARCHAR(100) NOT NULL,
   PRIMARY KEY ( id )
);

然后在您的PHP代码中

mysql_query("INSERT INTO users(Name_person,Name_father,Name_mother) VALUES ('$personname','$fathername','$mothernname')");  


$user_id = mysql_insert_id();

$query = "INSERT INTO family_members (user_id,no_members,name_members,age_members,relation_members,occupation_members) VALUES ";
$queryValue = "";
for($i=0;$i<$itemCount;$i++) {
    if(!empty($_POST["name1"][$i]) || !empty($_POST["name2"][$i]) || !empty($_POST["name3"][$i]) || !empty($_POST["name4"][$i]) || !empty($_POST["name5"][$i])) {
        $itemValues++;
        if($queryValue!="") {
            $queryValue .= ",";
        }
        $queryValue .= "('".$user_id. "', '" . $_POST["name1"][$i] . "', '" . $_POST["name2"][$i] . "', '" . $_POST["name3"][$i] . "', '" . $_POST["name4"][$i] . "', '" . $_POST["name5"][$i] . "')";
    }
}
$sql = $query.$queryValue;

此外，您可以轻松获取JOIN记录或只是

假设你想获得用户1的记录

$get_user = mysql_query("SELECT * FROM users WHERE id = 1");
$user = mysql_fetch_assoc($get_user);
$user_id = $user['user_id'];


echo '<table>';
echo '<tr><th colspan="5">Recod of User '.$user['Name_person'].'</th></tr>';
$get_user_family = mysql_query("SELECT * FROM family_members WHERE user_id = '$user_id'");
while ($family = mysql_fetch_assoc($get_user_family))
{
    echo"<tr><td>".$family['no_members']."</td><td>".$family['name_members']."</td><td>".$family['age_members']."</td><td>".$family['relation_members']."</td><td>".$family['occupation_members']."</td></tr>";
}
echo '<table>';
