PHP 事件日历。 javascript按钮不会按下

标签 php javascript css xampp

我一直在关注一个关于如何制作 php 日历的非常烦人的教程。我已经到了最后一点，但是我有一个按钮可以在某些日期显示数据库中的信息，当我单击它时没有任何反应。它应该调出一个显示信息的框。没有错误消息或任何东西，当您单击它时什么也没有发生。也许我犯了一个简单的错误？有人有什么想法吗？我今晚需要完成这个:( 谢谢

事件.php

<?php
$deets = $_POST['deets'];
$deets = preg_replace('#[^0-9/]#i', '', $deets);

include ("connect.php");

$events = '';
$query = mysql_query('SELECT description FROM events WHERE evdate = "'.$deets.'"');
$num_rows = mysql_num_rows($query);
if($num_rows > 0) {
$events .= '<div id="eventsControl"><button onMouseDown="overlay()">Close</button><br /><br /><b> ' . $deets . '</b><br /><br /></div>';

while($row = mysql_fetch_array($query)){
  $desc = $row['description'];
  $events .= '<div id="eventsBody">'. $desc . '<br /><hr><br / ></div>';
 }
}
echo $events;
?>

连接.php

<?php
$db_host = "localhost";
$db_username = "root";
$db_pass = "heyman";
$db_name = "ecalandar";
$conn = mysql_connect("$db_host", "$db_username","$db_pass") or die ("could not connect                          
to mysql");
mysql_select_db("$db_name") or die ("no database");
?>

最佳答案

没有仔细查看您的代码，我注意到您正在将字符串传递给您的(过时且危险的)mysql 函数

$db_host = "localhost";
$db_username = "root";
$db_pass = "heyman";
$db_name = "ecalandar";
$conn = mysql_connect($db_host, $db_username,$db_pass) or die ("could not connect  to mysql");
mysql_select_db($db_name) or die ("no database");

你应该读读 pdo/mysqli
