Empire CMS Anti-irrigation, anti-spam message

There is a message board on the website, the server has been black recently, often a lot of rubbish. Just like the following:

In order to prevent spam, to the backend management staff to reduce workload, I suggest matching content, filter messages, but one team members do not agree that the opening of the verification code is more reasonable.

I had more important things in hand then I did it by exclusivity.

In my habit, I would not be able to fill in the contents of the verification code, especially if it was difficult to see, if I asked for a suggested message. Even if a mailbox site to register three times, five times the input registration code, it is a test of patience, and waste other people's time.

As a result, one weeks after the opening of the verification code, no message backstage.

So it closed again, but the rubbish came again.

or back to my original proposal, because the long image of the garbage is very characteristic, and the user's comments are very distinctive, so, as long as the match is OK. This method is for the reference of the friend who needs this aspect.

The specific method is as follows.

Modify File: e\enews\gbookfun.php

Modified as follows:

Post Message function Addgbook ($add) {Global $empire, $dbtbpre, $level _r, $public _r;
	Verify IP echeckaccessdoip (' Gbook '); Checkcanposturl ();
	Verify source $bid = (int) getcvar (' gbookbid ');
	if (empty ($bid)) {$bid = Intval ($add [bid]);
	$name = Reppoststr (Trim ($add [name]));
	$email = reppoststr ($add [email]);
	$call = Reppoststr ($add [call]);
	$lytext = Reppoststr ($add [Lytext]);
	if (Empty ($bid) | | | empty ($name) | |! Trim ($lytext)) {printerror ("Emptygbookname", "History.go (-1)", 1);
		///Match, if there is the injection of the machine, then directly omit if (! Preg_match ($pattern, $lytext)) {//verify code $keyvname = ' Checkgbookkey ';
		if ($public _r [' GBKEY_OK ']) {Ecmscheckshowkey ($keyvname, $add [' key '], 1);
		} $lasttime = Getcvar (' lastgbooktime ');
			if ($lasttime) {if (Time ()-$lasttime < $public _r [' regbooktime ']) {printerror ("Gbouttime", "", 1); }//Layout exists $BR = $empire->fetch1 ("select Bid,checked,groupid from {$dbtbpre}enewsgbookclass w")Here bid= ' $bid '; ");
		if (Empty ($br [bid])) {Printerror ("Emptygbook", "History.go (-1)", 1);
			}//permission if ($br [' GroupID ']) {$user = IsLogin (); if ($level _r [$BR [GroupID]] [level] > $level _r [$user [GroupID]] [level]) {Printerror ("Havenotenlevel", "histor
			Y.go (-1) ", 1);
		}} $lytime = Date ("y-m-d h:i:s");
		$ip = Egetip ();
		$userid = (int) getcvar (' Mluserid ');
		$username = Reppostvar (Getcvar (' mlusername ')); $sql = $empire->query (insert into {$dbtbpre}enewsgbook (name,email, ' call ', lytime,lytext,retext,bid,ip,checked, Userid,username) VALUES (' $name ', ' $email ', ' $call ', ' $lytime ', ' $lytext ', ', ' $bid ', ' $ip ', ' $br [checked] ', ' $userid ', '
		$username '); Ecmsemptyshowkey ($keyvname); Empty the Verification code if ($sql) {Esetcookie ("Lastgbooktime", Time (), times () + 3600 * 24);//Set last published $reurl = Doingretur Nurl ("..
			/tool/gbook/?bid= $bid ", $add [' Ecmsfrom ']);
		Printerror ("Addgbooksuccess", $reurl, 1); else {printerror ("DBerror "," History.go (-1) ", 1);
	}}else{Printerror ("Haveplclosewords", "History.go (-1)", 1); }
}

PS: Because different content, regular matching expression is not the same, here, I use variable $pattern instead.
