How to censor bad words with str_replace

[jiros1]

       

I'm trying to make a basic filter script for editing my games with str_replace.

I want to censor bad words with str_replace, but it's not working, it just returns the original input.

 

This is the contents of my function, it's activated when I submit the form:

        $game = Game::findOrFail($id);
        $filtered_game = str_replace('thefword', 'f***', $game);
        echo $filtered_game;

$game contains an array with 1 item: 

{"id":18,"name":"Dragonball3","category_id":2,"user_id":1,"created_at":"2015-12-03 11:35:04","updated_at":"2015-12-03 11:35:44","gamegroup_id":0}

The original game name is "dragonball3", when I put in the "F" word, my string won't be returned as "f***" but still as Dragonball3.

This function is originally intended for the edit functionality, which works perfectly but I have disabled this for testing purposes.

 

The output I want is this:

{"id":18,"name":"f***","category_id":2,"user_id":1,"created_at":"2015-12-03 11:35:04","updated_at":"2015-12-03 11:35:44","gamegroup_id":0}

Maybe there is a better way? I want to fix this but I think it's more important that I learn from this.

At what point in the script are inserting the F word? Because $game is reset to Dragonball3 when you execute the findOrFail() method above.

Thanks for the reply, I was trying this in Laravel and it didn't work, now I've fiddled with it in "vanilla" PHP and now it works.

I guess it was too soon for me to try something in a framework I haven't done yet.

the findOrFail method in laravel returns a model, not a string. You can't use str_replace on a model, that doesn't really make sense. You would want to do a str_replace on the name attribute of the game model IE

 

$game = Game::findOrFail($id);
$name = $game->name;
$newname = str_replace("fword", "f***", $name);
$game->name = $newname;
$game->save();

 

without any context though, I'm not entirely sure this is what you want.
