Php 如何将Post数组存储到mysql中

这是我的HTML动态表单。您可以添加n行，以添加多个产品

<input type="text" class="form-control cantClass" name="n_cantidad[]"/>
<input type="text" class="form-control autocompletModelo" id="modelo1" name="n_modelo[]"/>
<input type="text" class="form-control serieClass" name="n_serie[]"/>
<textarea readonly class="form-control descrClass" id ="descripcion1" rows="2" name="n_descripcion[]"/></textarea>

我可以这样做并插入MYSQL，它可以工作：

$sql = 'INSERT INTO ' . $bd_base . '.'.$bd_table.' (cantidad, modelo, serie, descripcion) VALUES ("' . $v_cantidad[0] . '", "' . $v_modelo[0] . '", "' . $v_serie[0] . '", "' . $v_descripcion[0] . '")';

如何将多行插入MySQL表？比如说

 $sql = INSERT ....var [0] var [0] var [0] var [0]
 $sql = INSERT ....var [1] var [1] var [1] var [1]

根据您使用的php版本，您可以使用mysql或mysqli

如果您使用的是最新的php版本，则首选Mysqli

常规插入请求如下所示：

INSERT INTO table_name (column1, column2, column3,...)
VALUES (value1, value2, value3,...)

在php中，可以将请求存储在字符串中：

$sql = "INSERT INTO table_name (column1, column2, column3,...)
VALUES ($val[0], $val[1], $val[2],...);"

然后使用mysqli执行它

以下是一个取自w3school的mysqli请求示例：

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 

$sql = "INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('John', 'Doe', 'john@example.com')";

if ($conn->query($sql) === TRUE) {
    echo "New record created successfully";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

$conn->close();
?>

如果该网站向公众开放，我还建议您使用准备好的查询过滤输入，以防止sql注入：

在任何数组上执行for循环，检查输入或筛选并插入：

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 

$sql = "INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('John', 'Doe', 'john@example.com')";

if ($conn->query($sql) === TRUE) {
    echo "New record created successfully";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

$conn->close();
?>
