Laravel bad wordfilter as a helper
I'm trying to make my own bad word filter, and it works great except when I have multiple words in a sentence. So now what it does is it takes the values from the database and then loops it and has to replace the words of the declaration.
Let me say that I (in Dutch) is a sentence Deze kanker zooi moet eens stoppen! Het is godverdomme altijd het zelfde zooitje.
. These are the words that need to be replaced in the database:
kanker
and godverdomme
.
So, I have in my database:
All is well, except that 2 hordes have to be replaced, then he doesn't want to replace ...
My helper function:
public static function Filter($value)
{
$badwords = DB::table('badwords')->get();
foreach ($badwords as $badword)
{
$replaced = str_ireplace($badword->bad_word, $badword->replacement, $value);
}
return $replaced;
}
Hope someone can help me :)

For each iteration in your foreach loop, you set the value $replaced
to what it returns str_ireplace
.
At the end of the function, you will return a value in which only the last bad word should be replaced.
str_ireplace
takes either a single string value or an array of string values to replace as the first and second parameters, which means that you could instead create two arrays that you fill in in a loop foreach
and then run str_ireplace
after the loop, something like:
$words = [];
$replace = [];
foreach ($badwords as $badword) {
array_push($words, $badword->bad_word);
array_push($replace, $badword->replacement);
}
return str_ireplace($words, $replace, $value);
