Question

我正在尝试连接到XAMPP MySQL数据库以添加新记录。我相信我做的一切都正确，但由于某种原因，我的数据库表中没有添加新行。任何人都可以查看代码并告诉我什么是错的？提前谢谢。

<?php
error_reporting(0);
$connect = mysql_connect('localhost','root','');
mysql_select_db("projects", $connect);
$button = $_POST['button'];
$username = $_POST['username'];
$seatingplan = $_POST['seatingplan'];
$numberofseats = $_POST['numberofseats'];
$date= $_POST['date'];
$branch = $_POST['branch'];

if ($button)
{
if($username && $seatingplan && $numberofseats && $date &&$branch)
{
mysql_query("INSERT INTO reservations(Username, Seating plan, Number of seats, Date, Branch)VALUES('$username','$seatingplan','$numberofseats,'$date','$branch')");
}
else
echo"You did not fill in the fields";
}
?>

Answer 1

如果列名中有spaces，则需要使用字符“

封装列名称

 mysql_query("INSERT INTO reservations(`Username`, `Seating plan`, `Number of seats`, `Date`, `Branch`) VALUES('$username','$seatingplan','$numberofseats,'$date','$branch')");

Answer 2

您必须记住db field_name这样的事情不应该有空格，其次您没有检查过该按钮，值是set还是最后一件事是使用concatenation在query中，或在代码下面替换

<?php
if(isset($button))
{
  if(isset($username && $seatingplan && $numberofseats && $date &&$branch))
  {
   mysql_query("INSERT INTO reservations (`Username`,`Seating plan`,`Number of seats`,`Date`,`Branch`)VALUES('".$username."','".$seatingplan."','".$numberofseats."','".$date."','".$branch."')");
}

Answer 3

我认为查询错误试试这个

mysql_query("INSERT INTO reservations(`Username`, `Seating plan`, `Number of seats`, `Date`, `Branch`) VALUES('".$username."','".$seatingplan."','".$numberofseats."','".$date."','".$branch."')");

Answer 4

您无法在列名称中添加空格

错误

mysql_query("INSERT INTO reservations(Username, Seating plan, Number of seats, Date, Branch)VALUES('$username','$seatingplan','$numberofseats,'$date','$branch')");

在更正colunm名称后尝试以下代码。您可以使用_代替列名称中的空格。

<强> PHP

<?php error_reporting(0); $connect = mysql_connect('localhost','root',''); mysql_select_db("projects", $connect); $button = $_POST['button']; $username = $_POST['username']; $seatingplan = $_POST['seatingplan']; $numberofseats = $_POST['numberofseats']; $date= $_POST['date']; $branch = $_POST['branch']; if ($button) { if($username && $seatingplan && $numberofseats && $date &&$branch) { mysql_query("INSERT INTO reservations(Username, Seating_plan, Number_of_seats, Date, Branch)VALUES('$username','$seatingplan','$numberofseats,'$date','$branch')"); } else echo"You did not fill in the fields"; } ?>
