php - 一次将多行插入MySQL

Question

我试图立即提交一张充满信息的表格，但找不到答案。向数据库提交一组信息没有问题，但我需要一次侮辱 1 到 50 个相同的值。这是一个例子:

我们正在记录单圈时间，因此我们需要能够在网络应用程序上填写表格，其中包含大量姓名和赛事时间。因此，我们需要立即添加大量 SQL 条目。

我尝试过复制并粘贴表单信息，但这会导致 phpmyadmin 中出现一组空白数据。

这是代码:

<?php


$host = "localhost";
$databasename = "pe_results";
$databaseusername = "root";
$databasepassword = "";

$conn = mysql_connect("$host", "$databaseusername", "$databasepassword"); 
mysql_select_db("$databasename", $conn); 

        if (isset($_POST['Name'])) { 
        $Name = $_POST['Name'];
        }
        if (isset($_POST['Short'])) { 
        $Short = $_POST['Short'];
        }
        if (isset($_POST['Med'])) { 
        $Med = $_POST['Med'];
        }
        if (isset($_POST['Long'])) { 
        $Long = $_POST['Long'];
        }
        if (isset($_POST['VLong'])) { 
        $VLong = $_POST['VLong'];
        }
        if (isset($_POST['Extreme'])) { 
        $Extreme = $_POST['Extreme'];
        }
        if (isset($_POST['LJump'])) { 
        $LJump = $_POST['LJump'];
        }
        if (isset($_POST['HJump'])) { 
        $HJump = $_POST['HJump'];
        }
        if (isset($_POST['Shotputt'])) { 
        $Shotputt = $_POST['Shotputt'];
        }
        if (isset($_POST['Discuss'])) { 
        $Discuss = $_POST['Discuss'];
        }
        if (isset($_POST['Javelin'])) { 
        $Javelin = $_POST['Javelin'];
        }
        if (isset($_POST['Date'])) { 
        $Date = $_POST['Date'];
        }
        if (isset($_POST['Year'])) { 
        $Year = $_POST['Year'];
        }



           $i = count($Name);

for ($i=0;$i<10;$i++) {
$n = $Name[$i];
$s = $Short[$i];
$me = $Med[$i];
$lng = $Long[$i];
$slng = $VLong[$i];
$ext = $Extreme[$i];
$ljump = $LJump[$i];
$hjump = $HJump[$i];
$shot = $Shotputt[$i];
$disc = $Discuss[$i];
$jav = $Javelin[$i];
$date = $Date[$i];
$year = $Year[$i];

//and so on with more variable...

$sql="INSERT INTO results_main (`Name`, `Short`, `Med`, `Long`, `Vlong`, `Extreme`, `LJump`, `HJump`, `Shotputt`, `Discuss`, `Javelin`, `Date`, `Year`)
            VALUES ('$n', '$s', '$me', '$lng', '$slng', '$ext', '$ljump', '$hjump', '$shot', '$disc', '$jav', '$date', '$year')";

}


    $result = mysql_query($sql) or die(mysql_error ());;
        if($result){
echo"<br/>Everythings been saved";
echo "<BR>";
echo "<a href='index.php'>Back to the main page</a>";
}

else {

echo $result = mysql_query($sql,$conn) or die (mysql_error ());
}

// close connection 
mysql_close($conn);
?>

<?php
// Create connection
$con=mysqli_connect("127.0.0.1","root","","pe_results");

// Check connection
if (mysqli_connect_errno($con))
  {
  echo "Uh oh, tell chris that " . mysqli_connect_error() . "NO DATA WILL BE SAVED";

Answer 1

如果我正确理解你的问题，你想做的就是用 [] 命名字段。所以

<select name="Year">

成为

<select name="Year[]">

然后您将能够循环提交的值，例如:

foreach($_POST['Year'] as $k=>$v){
 echo $v." - This is the value";
 echo $k." - This is the key";
}

编辑:

(string)$insert;
if(is_array($_POST['Year'])){
    foreach($_POST['Year'] as $k=>$v){  
         $insert .= "(".$_POST['Name'][$k].", ".$_POST['Short'][$k].", ".$_POST['Med'][$k].", ".$_POST['Long'][$k].", ".$_POST['VLong'][$k].", ".$_POST['Extreme'][$k].", ".$_POST['LJump'][$k].", ".$_POST['HJump'][$k].", ".$_POST['Shotputt'][$k].", ".$_POST['Discuss'][$k].", ".$_POST['Javelin'][$k].", ".$_POST['Date'][$k].", ".$_POST['Year'][$k]."),"; 
    }
     $insert = substr_replace($insert ,0,-1);
}else{
    $insert .= "($_POST['Name'], $_POST['Short'], $_POST['Med'], $_POST['Long'], $_POST['VLong'], $_POST['Extreme'], $_POST['LJump'], $_POST['HJump'], $_POST['Shotputt'], $_POST['Discuss'], $_POST['Javelin'], $_POST['Date'], $_POST['Year'])"; 
}
$sql="INSERT INTO results_main 
(`Name`, `Short`, `Med`, `Long`, `VLong`, `Extreme`, `LJump`, `HJump`, `Shotputt`, `Discuss`, `Javelin`, `Date`, `Year`)
VALUES 
".$insert;

这应该能够将所有内容都放入一个查询中，而不是对每一行执行多个查询
