php - 将数组值从表单插入mysql

Question

我有 3 个 PHP 文件，在 select.php 文件中，您必须选择所需的表单数量。该表单包含 3 个输入字段。如下:

  <form method="post" action="index.php" >
     Continue insertion with <select name="counters" id="insert_rows">
    <option value="1">1</option>
    <option value="2" selected="selected">2</option>
    <option value="3">3</option>
    </select>
     rows
    <input type="submit" value="Go" />
    </form>

选择插入数量后，会将数量传递给index.php，其中包含:

<?php
    echo "<form method = 'POST' action = 'process.php'>";
    for($counter = 0; $counter < $_POST['counters']; $counter++)
    {
        echo "Service Name: <input type = 'text' name = 'name[]' class = 'class_name'/><br/>";
        echo "Service Version :    <input type = 'text' name = 'version[]' class = 'class_name'/><br/>";
        echo "Service type :    <input type = 'text' name = 'type[]' class = 'class_name'/><br/>";
    }
    echo "<input type = 'submit' value = 'SEND'/>";
    echo "</form>";
?>

第三个文件process.php包含

<?php

    $name = array();
    $version = array();
    $type= array();

    $name = $_POST['name'];
    $version = $_POST['version'];
    $type= $_POST['type'];

    for($counter = 0; $counter < sizeof($name); $counter++)
    {
        echo "service_name #".($counter + 1).": ".$name[$counter]."<br />";
        echo "service_version #".($counter + 1).": ".$version[$counter]."<br />";
        echo "service_type #".($counter + 1).": ".$type[$counter]."<br />";
    }
    ?>

在我将值传递给它之后，它正确显示数据，如下所示

service_name #1:现在不行服务版本#1:v1service_type #1:私有(private)service_name #2: 类达尔服务版本#2:v2service_type #2:公共(public)

所以我的问题是:如何在“process.php”文件中创建一个函数以将所有这些值插入数据库。

我创建了一个名为“服务”的表，其中包含“名称、版本、类型”这些列

我会等待您的支持。谢谢

我建议将第一个提交的计数值保存在第二种表单的隐藏输入中，然后您将能够循环遍历并插入数据

<?php
  echo "<form method = 'POST' action = 'process.php'>";
  for($counter = 0; $counter < $_POST['counters']; $counter++)
  {
     echo "Service Name: <input type = 'text' name = 'name[]' class = 'class_name'/><br/>";
     echo "Service Version :    <input type = 'text' name = 'version[]' class = 'class_name'/><br/>";
     echo "Service type :    <input type = 'text' name = 'type[]' class = 'class_name'/><br/>";
  }
  echo '<input type="hidden" name="cntr" value="'.$_POST['counters'].'" />'
  echo "<input type = 'submit' value = 'SEND'/>";
  echo "</form>";
?>

现在在您的 process.php 中您将拥有:

if (!empty($_POST['cntr'])) {
   $query = 'INSERT INTO services (name, version, type) VALUES ';
   for ($x = 0; $x < $_POST['cntr']; $x++)
   {
      $query .= "('".mysqli_escape_string($_POST['name'][$x])."','"
                    .mysqli_escape_string($_POST['version'][$x])."','"
                    .mysqli_escape_string($_POST['type'][$x]).
                "'),";
   }
   $query = substr_replace($query, '', -1);

   mysqli->query($query);
}

我准备的只是一个示例，您可以根据您的更改进行修改
