BAN words, number and emails in a text area

perfexa · April 12, 2011

Hi all, please bare with me i am a newbie to this forum, i will try my best to provide all clear accurate information where possible, please find a below breakdown, i've had a little help from a user already but as am still getting problems and confused i will take his advise am post it in the right place !

1) I have the below code and wish to ban specifc words, numbers and emails of my choice.

2) If the users enter a baned word etc either nothing will happen or it will forward them to another page.

Please find attached index.php which is full working script of where i wish to add my banned words code too, also please find attached indextest.php containing the working script and code of bannng specfic words that i can't get to work.

When i run indextest.php on my linux server the whole page displays perfectly but when you enter a baned or unbaned word and click submit nothing happens at all, so am very confused to where am going wrong.

Any kind, helpfull guides to what i'm doing wrong would be highly appriciate as i do want to learn from my mistakes.

All the best

Steve

As for the match of ban words use something like this.

<?php

$badwords = array(
			  'monkey',    
			  'banana',    
			  'justin bieber',   
			  'barbara streisant'
);
$pattern = implode("|",$badwords);

echo "$pattern<br />";//just to see them

if(preg_match("/$pattern/i", trim($_POST['ename']))){
	echo 'die!';
	}else{        
	echo 'proceed';

	}
	   
	   ?>
<form action="" method="post">
Name or Email: <input type="text" name="ename" />
<input type="submit" />
</form>

As for any includes you got for api's and w/e, nobody can run the same script you are.

I did manage to get it connected by excluding some includes, but I had nobody to talk to.

QuickOldCar · April 12, 2011

Use similar to this pattern for "exact" instead of the "if contains" in previous code I did.

if(preg_match("/\($pattern\)/i", trim($_POST['ename']))){

Cheers, but this is where i'm falling down i think after insterting the php code how to i put this code in conjunction with the form code on yours for it to work

<?php } else { ?>
<form action="index.php?do=start" method="post" >
<fieldset style="width: 120; height: 60; font-size: 18px;">
<legend><span class="Facekandi"><font color="#F0F0F0">Enter your Apple Facetime ID</font><font color="#0066FF">*</font></span></legend>
<input type="text" name="facetimeid" class="userinput" maxlength="35" size="37" />
</fieldset>

<input type="image" src="button.png" class="usersubmit" />
[code]

QuickOldCar · April 12, 2011

I think this should work, just replaced the one line and used your facetimeid value

<?php
require ('settings.php');
require('functions.php');
session_start();

if ($_GET['do']=='start') {
    if ($_POST['facetimeid']=='') { header("Location:".SITE_BASE); } else {
    
    include('init.php'); }
} elseif ($_GET['do']=='random') {
    // Make sure we have a session, otherwise redirect to homepage
    if ($_SESSION['CurrentUser']=='') { header("Location:".SITE_BASE); }
}

?>

Your check for the bad word just echoes die or proceed, you would have to place an exit and header redirect, die or w/e if want to actually stop them from using it.

perfexa · April 12, 2011

I've just tried it and now i'm getting a HTTP500 error

QuickOldCar · April 12, 2011

Does your original index.php file execute and work properly before the check for preg_match?

Maybe your server is down?

it is a 500 error

perfexa · April 12, 2011

servers not now, everything was working fine before i copieed all the code

QuickOldCar · April 12, 2011

Whenever your server works again try this one.

I moved the check for bad words up to the top, is no need to execute the script any further than that if they aren't allowed.

Also added a header redirect with a message.

This was from your original index.php file

<?php
require ('settings.php');
require('functions.php');
session_start();
$badwords = array('monkey',    
  'banana',    
  'justin bieber',   
  'barbara streisant'
);
$pattern = implode("|",$badwords);
if(preg_match("/$pattern/i", trim($_POST['facetimeid']))){
header( "refresh:5;url=index.php" );
echo 'Not allowed, You\'ll be redirected in about 5 secs. If not, click <a href="index.php">here</a>.';
EXIT;
} else {
if ($_GET['do']=='start') {
    if ($_POST['facetimeid']=='') { header("Location:".SITE_BASE); } else {
    
    include('init.php'); }
} elseif ($_GET['do']=='random') {
    // Make sure we have a session, otherwise redirect to homepage
    if ($_SESSION['CurrentUser']=='') { header("Location:".SITE_BASE); }
}

Hi QuickOldCar

Sorry i ment to say my server was never down, the server is still working fine, i've tried both codes you modified and everytime i upload and try it i get a HTTP500 error and when i replace it with the unmodified (normal) code it works fine.

Any ideas

QuickOldCar · April 13, 2011

I don't know why it's doing that.

I can run the code on my server if i eliminate the includes and the first if statement regarding the api.

Could it be your copy/paste is converting the quotes?

Try using notepad2

http://sourceforge.net/projects/notepad2/

perfexa · April 13, 2011

I've got no idea either its weird, i just copy and paste into dreamweaver save as php and upload then HTTP500

What do you think is the best way forward?
