简单的shout box php实现

Nov 18, 2005 Author: | Filed under: Uncategorized

很不错，我就喜欢这种短小精干的代码，sourceforge的那个shoutbox弄了半天也没装好…

建库 shoutbox，然后建表，用 phpadmin 的sql命令行

CREATE TABLE shoutbox ( id INT(11) NOT NULL AUTO_INCREMENT, message TEXT NOT NULL, author VARCHAR(80) NOT NULL, eml VARCHAR(50) NOT NULL, date VARCHAR(50) NOT NULL, ip VARCHAR(20) NOT NULL , PRIMARY KEY (id)) 显示更多

php code 另存为shoutbox.php

<?php // You just need to configure these 4 variables to match your server. $db_host = "localhost"; // mySQL database host $db_user = "username"; // mySQL database user $db_password = "password"; // mySQL database password $db_name = "database"; // the name of your mySQL database // If a user has submitted a post, we want to : // 1. Validate it // 2. Strip unwanted html // 3. Make sure messages and names aren't too long // 4. Add it to our database. if($_POST['submit']) { // 1. Validate it, by checking all the form inputs were filled in if(!$_POST['author']) { echo 'Error ! : No name entered'; die; } if(!$_POST['eml']) { echo 'Error ! : No email entered'; die; } if(!$_POST['message']) { echo 'Error ! : No message entered'; die; } // 2. Strip unwanted HTML // Look up the strip_tags() function at // http://www.php.net/manual/en/function.strip-tags.php for more info $message = strip_tags($_POST['message'], ''); $eml = strip_tags($_POST['eml'], ''); $author = strip_tags($_POST['author'], ''); // 3. Make sure messages and names aren't too long // We will use the strlen() function to count the length. $message_length = strlen($message); $author_length = strlen($author); if($message_length > 150) { echo “Error ! : Your message was too long, messages must be less than 150 chars”; die; } if($author_length > 150) { echo “Error ! : Your name was too long, names must be less than 150 chars”; die; } // 4. Add it to our database. // If the script hasn’t died yet due to an error in the inputted data // we need to add the data to the database // Lets connect to our database. mysql_connect($db_host,$db_user,$db_password) or die(mysql_error()); // Select the database. mysql_select_db($db_name) or die(mysql_error()); // Lets define the date format we want to enter to our database // go here for more details // http://www.php.net/manual/en/function.date.php $date = date(”h:i A dS M”); // This will produce 11:02 25th Aug // Set the query as $query $query = “INSERT INTO shoutbox (message, author, eml, date, ip) VALUES (’$message’,'$author’,'$eml’,'$date’,'$_SERVER[REMOTE_ADDR]‘)”; mysql_query($query); mysql_close(); // Show thanks message and take them back to the main shoutbox echo “Thanks for your post “; echo “<A HREF='shoutbox.php'>View the shoutbox</A>“; // If they haven’t submitted a post, we want to : // 1.
