Bad Words

[anevins]

: : NEW Problem

 

I want to replace bad words which someone has inputted into my HTML textarea, with something like [CENSORED].

Here's what I've got so far:

note: $review is the posted textarea name.

Code: [select]

 

$words_text = 'badwords.txt';

$bad_words = file($words_text);

 

$good_words = str_ireplace($bad_words,'[CENSORED]',$review);

 

echo $good_words;

 

 

The thing is, if I type bad words in the textarea, I still get bad words when I echo $good_words.

 

I don't know why I'm getting this, any ideas

[matthew9090]

change

 

$bad_words = file($words_text);

 

to

 

$bad_words = file_get_contents($words_text);

 

i think

[anevins]

fopen requires 2 parameters

[matthew9090]

i meant file_get_contents

[anevins]

same result as first post.

 

Note: The variable $bad_words does have the value of the text file.

[Pikachu2000]

Is the text file in the same directory as the script that's calling the file() function?

[anevins]

Yeah, if I var_dump $bad_words, I get the file contents.

 

This is the example I'm trying to follow (this code works)

$words = array('apple','orange','banana');
$string = 'How was your apple? I like oranges! But bananas are even better!';
$fixed = str_ireplace($words,'(SNIP)',$string);
echo "String: $string<br><br>Fixed: $fixed<br>";

there is a tutorial about this: http://www.youtube.com/watch?v=5y1HyQLg2dU&list=PLFA954987101252EF&index=25

I also made a bad words filter to do single words or entire posts.

 

The demo is there, able to download, can also see the code below the demo.

One day I'll have to make this a function, but was never at the top of my list.

That looks really complicated to me, I don't think I will be able to understand it just for a simple form textarea box

[anevins]

I checked that video out Matthew, it's all good until you have to create a replace array.

I have over 500 words, therefore it would be impractical to create an array to replace the 500 words, specifying the swearing format in each word.

I think that's the same as Matthew's example.

I can't use those replacing arrays as it requires me to specify what the new format of each word will be, as I have too many words.

 

I'm using the file() function to load in the text file with my words, into an array called $bad_words

[The Little Guy]

assuming your file has one word per line:

 

<?php
$file = 'myfile.txt';
$handle = fopen($file, 'rb');
$contents = fread($handle, filesize($file));
fclose($handle);

$words = explode("\n", $contents);

function censor($string){
    $total = strlen($string);
    return str_repeat("*", $total);
}
echo preg_replace("/(".implode("|", $words).")/ie", 'censor($0);', $_POST['text']);
?>

[anevins]

 

Warning: preg_replace() [function.preg-replace]: Compilation failed: nothing to repeat at offset 2644 in ... line 54

 

line 54:

echo preg_replace("/(".implode("|", $words).")/ie", 'censor($0);', $_POST['text']);

does your file have an extra new line with nothing there? if so remove it, I think I got the same error because of that. Make sure there are no empty lines in the file.

[anevins]

All lines are accounted for, there are no empty lines

[The Little Guy]

try changing this line:

$contents = fread($handle, filesize($file));

 

To this:

$contents = preg_quote(fread($handle, filesize($file)));

another filter...

Reply to the little guy,

 

Nothing is returned now.

[The Little Guy]

try changing this line:

$words = explode("\n", $contents);

 

To this:

$words = explode("\r\n", $contents);

 

and btw, here is an example of a working copy:

if your text file has 1 per line then you need to read it line by line and somehow put each line into an array which if your using that tutorial i gave u.
