Question

我正在尝试使用PHP在MySQL数据库中一次插入多行。我想在3个不同的行中插入a，b，c，但它以1，b，c格式插入1行。

我的代码如下所示，它没有给我任何错误，因为代码完美无缺，但我无法得到我想要的结果。

<?php
require_once('conn.php');
$name = $_POST['name'];
 if($name)
 {
    foreach($name as $std_name)
    {
    $student[] = $std_name;
    // implode($c); i.e a,b,c etc
    }
 }
$sql = "INSERT INTO `tbl_student` 
 (`student_name`) 
 VALUES 
 ('".implode($student, ',')."');";
 $res = mysql_query($sql);
?>

Answer 1

提出此查询

$sql = "INSERT INTO `tbl_student` 
 (`student_name`) 
 VALUES 
 ('".implode($student, ',')."');";
 $res = mysql_query($sql);

在foreach块内不要使用implode使用，或者使用以下查询作为

$sql = "INSERT INTO `tbl_student` 
 (`student_name`) 
 VALUES 
 ('". $std_name."');";

所以它会在不同的行中添加每一个

Answer 2

使用此：

$val="('".implode("'), ('",$student)."')";
        $sql = "INSERT INTO `tbl_student`
 (`student_name`) VALUES ".$val.";";

使用Ajax + php在mysql表中同时添加多条记录
