[PHP] How do I...

[xRoyal15]

Oki, this will take some explaining.

I have the code:

:ban xRoyal15 

Now, :ban is the function, xRoyal15 is the username.

I want to extract the username from that code, and use it.

So, someone types

:ban xRoyal15 

It extracts the username (xRoyal15) from that shout, and ban it.

How would I go about extracting the username from the code?

Well first you would need to set up somthing to match the :ban so the function first activates, then you can use preg replace to remove the ":ban " bit and be left with the use name, you could then hash that to an id, and do what ever you like "/

preg_match plus preg_replace usin kinda stuff... very vaige and random i know, but im lazy, if you want a more detailed exsplination just tell me, and if i have time ill actulay provide more helful info on the sort of code... if your already good with php, and it was just a conceptal prob, hopefuly my vage crap will have helped anyway

Yer, im good with php, but i still sorta confused.

Good you go into more detail, maybe show me an example :rolleyes:

How much of the shout box do you have working so far?

Basicly every time someone says somthing, you wana look at the code for adding that to the DB.

Then you want to use preg_match in an if statment around it.
aka *persudo code*
if preg_match finds the text "ban:" in the input

Do the ban stuff here, aka preg_replace the text "ban: " and get the username.
Then useing the usename, updated the mysql to ether set somthing in there account to banned, or add there ip to a blocked list or somthing

Else (if its not ban)

Normal code to add new shout here

end if

It all works so far, so what you mean is...

if(preg_match == :ban){
preg_replace(:ban)
}else{
STUFF
}

Tried and tested way:

<?php
$ban = ":ban xRoyal15";
echo $ban;
$ban = explode(" ", $ban);
$ban['0'] = "";
$ban = implode("", $ban);
echo "<br />$ban"; //In quotes so I can use <br />
?>

I guess you're not as good with php as I first thought. ;>

Ah no... what happens is...

Shoutbox > Admin types :Ban x (x being user) > preg_match finds :Ban, > preg_replace removes :ban to just give x > $banuser = x > bans x

So i need this bit preg_match finds :Ban, > preg_replace removes :ban to just give x > $banuser = x >

and i can do the rest

On the shoutbox:

$name = $logged[username];
$shout = $_POST[shout];

Shoutbox > Admin types :Ban x (x being user) > preg_match finds :Ban, > preg_replace removes :ban to just give x > $banuser = x > bans x

So i need this bit preg_match finds :Ban, > preg_replace removes :ban to just give x > $banuser = x >

and i can do the rest

On the shoutbox:

$name = $logged[username];
$shout = $_POST[shout];

Do you wanna make yourself clearer? I just gave you something that gives the username from a string, what do you want exactly?

edit:
oh wait, gotcha, code in a minute.

[xRoyal15]

1. User posts shout ($shout)
2. If($logged[level] == 12){
3. Does a preg_match to find if it has :ban in it
4. If it does, it removes the ban, to give the username
5. username can then be used to ban the user
6. }else{
7. Inserts into database as a post

Clear as i can be

Edit: Just seen ya edit, oki

<?php
if ($logged[level] == 12)
    {
        $shout = ":ban xRoyal15"; //Assume this is $_POST[shout]
        if (stristr($shout, ":ban"))
            {
                $ban = explode(" ", $ban);
                $ban['0'] = "";
                $ban = implode("", $ban);
                //Function or whatever to ban the user here.
            }
    }
?>

stristr > preg_match

(preg_match returns an array)

That *should* work.
