Basically I'm looking for somewhat of what b2 offers, namely the ability to call/query data with a simple URI caller, e.g: http://what.com/index.php?var1=x&var2=y&var3=z

Now,
var 1 is an integer which - when called - will echo a small string of text (1 sentence out of 60).
var2 is an integer which will "echo" one of 15 images
var3 a boolean either displaying picture 1 or picture 2.

_Then_ I need a way of using ({i]+1) and -1 to navigate back and forth.

Any ideas on what I should look into? I love to learn from examples.
I'm a total php n00b, just so it's said.

Taking it one step further...

Thanks to netcode.net, I was able to find a script that would allow me to do this using a db table, for which I'm glad.

There are a few issues, though.
    1. Ever heard about $sql? ... I get a parse-error on that'n.
    2. I was wondering wether the php_next() and prev() could be used as navigation links (<< and >>) which will define the querystrings that I'll use for retrieving the correct data. Any ideas on how/if this could be done?

All help appreciated:)

Disregard last two:)

All I need to know is how I can make multiple querys as in b2.. (e.g. index.php?c=1&tb=1)

I have one file- middle.php - calling images by ?ch=X where x is a number between 0 and 15.
I have 2nd file - dialogue.php - defining integers 0-60 as text strings. (Doesn't work yet, but I'll get there..)

I need to include both of these in a third file (middle.php will be used in other files identical to the 2nd one, so it needs to be "absolute") without disrupting the arrays of the 2nd one. So, I checked b2's isset? Any tips on how to do this?

I don't think I understand what you want but if it helps you can work with a single query if you like. So ch=10, somethingelse=30 becomes myvariable=10_30 as in
Code:
$myvariable=$ch."_".$somethingelse;

Then you can recover the 2 variables using explode:
Code:
$bang=explode("_",$myvariable);
$ch=$bang[0];
$somethingelse=$bang[1];

That's actually alot of help, cheers:)

The concept is pretty simple, but the design is not.
There are 15 characters ($ch) and 60 lines ($say).
Instead of writing a fixed setup, I want to make a system that allows me to (more) easily add new "episodes" to the comic.
Of course I could've hacked b2 and used the db, but I already have 2 blogs on my server so I wanted to try something else.

At the time, I've got the lines of the script in one file (which I'll include with an isset or something, for security) the characters in another and a third frameset-file calling the cycle of steps, which again is a forth file.

Ok, here's the deal. Using this code:
Code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<?php
   
   $eistr=$char."_".$sayline;
   $bang=explode("_",$eistr);
   $char=$bang[0];
   $sayline=$bang[1];

# great tip by Stevem:)

# example: echo "Character $ch says $sayline".. just a note..

$what = Array('1' => 'So..',
'2' => 'Yep..',
'3' => 'Any news?',
'4' => 'What did he say?',
'5' => 'Andrew asked if there was any news',
'6' => 'Oh, he did, did he?',
'7' => 'Yes..',
'8' => 'Huh..',
'9' => 'Haven`t seen Logan for a while..',
'10' => 'He is still at the far right.',
'11' => 'LOGAN!?',
'12' => 'YES?!',
'13' => 'THIS IS LEONARD!!',
'14' => 'HI!!!',
'15' => 'Can you please shut up?',
'16' => 'IT`S BEEN A LONG TIME!!!',
'17' => 'What are they yelling about?',
'18' => 'YEAH! WHAT`S THE VIEW LIKE FROM THERE!??',
'19' => 'What did he say?',
'20' => 'Logan asked what the view was like from here.',
'21' => 'Oh! Tell him it`s good.',
'22' => 'IT`S GOOD!',
'23' => 'Do you mind?',
'24' => 'Shh!',
'25' => 'Ask him if he can see anything!',
'26' => 'CAN YOU SEE ANYTHING??!',
'27' => 'What`s all this noise about?',
'28' => 'Leonard is talking with Logan.',
'29' => 'Oh, they`re at it again, eh?',
'30' => 'NAAAHH! I SAW A SHIP TWO MONTHS AGO!!',
'31' => 'This is so lame.',
'32' => 'YOU DID?! SO DID WE!!',
'33' => 'OH? WHO`S WITH YOU?',
'34' => 'Can you stop shouting?',
'35' => 'Yeah! Shut up!',
'36' => 'You shut up! LOGAN! IT`S RICHARD HERE WITH ME! LIKE LAST TIME!!',
'37' => 'AAAAAHH..',
'38' => 'What did he say?',
'39' => 'I think he said ",Ahhhh",..',
'40' => 'Oh.',
'41' => 'That a plane?',
'42' => 'Naahh. Eagle again.',
'43' => 'Yup. That`s an eagle.',
'44' => 'Oh',
'45' => '*snif*',
'46' => 'Got a cold?',
'47' => 'Think I`ve got one coming. It`s quite brisky here, isn`t it?',
'48' => 'Yes, well, you know this time of year..',
'49' => 'Yes.. yes..',
'50' => 'IT WAS NICE TALKING TO YOU LEONARD!!',
'51' => 'Oh, I thought they were finished..',
'52' => 'Yeah, right.',
'53' => 'NICE TALKING TO YOU TOO LOGAN!!!',
'54' => 'Give him my best!',
'55' => 'AH.. RICHARD SAYS TO GIVE YOU HIS BEST!',
'56' => 'AHH YES! GOOD LUCK TO HIM TOO!',
'57' => 'He wished you good luck too.',
'58' => 'I heard.',
'59' => '*snif*',
'60' => '... I`ve got an itch..');

      <h3>
      <?php echo "{$what['$sayline']}"; ?>
      </h3>
   
   </div>   
</div>

</html>

And calling the file (base.php) by e.g. base.php?eistr=1_14
doesn't fetch anything..? No parse errors either..

Could $_GET be the thing?..

EDIT:
Live example up at..
http://www.sigg3.net/blogger/EasterIsland/base.php?eistr=1_14

Eventually I want the array to be included (the array in files named ep1.php, ep2.php etc.), but I'm aware of the risks so I also want to know the easiest yet safe way to do it:)

Whoops! You need to take out the line
Code:
$eistr=$char."_".$sayline;
since you want to read $eistr not define it

Put an array in ep1.php which is included in base.php but when run makes some sort of check. Set a variable not easy to guess in base.php and if ep1.php doesn't find the right value of this variable it aborts. Should make things a little harder for the casual user to get in.

Thanks alot, I'll give it a try!

On the include issue, I read that $isset is the right function to do this from a security point of view.

I don't want people to include external (and possible malicious) scripts.
But this might also be done by only allowing the call to be an INT.

EDIT:
Wohoo! It works! Had to change the last echo to print, but now it's on! Thanks alot!Smile
