Formatting GUI using PHP Server Script

Unity Engine
1

Hey guys, having some difficulties here. I’m trying to make a level list on my game. I have it working pretty well but I can’t get a button to appear after each listing (to play the level). Here’s what my script looks like…

PHP:

for($i = 0; $i < $num_results; $i++)
    {
         $row = mysql_fetch_array($result);
         echo ("Level name: " . $row['lvlname'] . 
		 "\nLevel Description: " . $row['description'] . 
		 "\nLevel Rating: " . $row['rating'] . 
                 "\nif(GUILayout.Button(\"Play!\")) { 
                      //Play Level
                 } 
		 \n\n\n");
    }

And in game, I have this script:

    var lvl_get = WWW("http://www.coreymccown.com/Unity/BallGame/levellist.php");
    yield lvl_get;
   
    if(lvl_get.error) {
        print("There was an error getting the level list: " + lvl_get.error);
    } else {
       LevelsText = lvl_get.text; // this is a GUIText that will display the level list
    }

And my result is:

(Pardon my mild swearing, just entertaining my boring self.)

I dunno what to do! Any help is greatly appreciated! Thanks! :slight_smile:

I’m a bit confused: what do you want this script to do? It appears to be sending a string to Unity, and you’re displaying it on the screen. If you want a button to show up, you’ll need to code that in. You might want to parse the string into chunks: one that gives the level name, one for the description, one for the rating, then put a button after each. GUILayout would be an easy way to do it.

The script is sending a string to Unity, yes. It displays everything (for the most part) how I want it to be displayed, but I want to be able to code the button on the PHP script, so where it says GUILayout.Button(“Play”) I plan on making that have the level ID and to play it, but in the game, it just comes up as text, not the button. I was hoping there was away to make that text be ran as a script, not the text… sorry for confusion.

That sounds like an over-complicated way of doing exactly what ncst said. If you know that every Level will be represented with three lines of text and then a button, you can just send the three lines of text and create a button in your game’s code. You don’t even need to parse the control type out of the input because this is such a simple problem (as opposed to generating different controls with varied parameters). You always know it’s a button, you always know what it says, and you can always define what the button does with a string or number sent in the PHP string.

Split the lines up in your game script, loop through them, and draw a button after each one.

You’re absolutely right! I dunno why my thick head didn’t comprehend this. Duh! Thanks! I’m trying to figure it out now… though I’m not sure where to start lol

If I were doing this (and I’m sure there are better ways), I might use symbols to separate each field (like ), and then a symbol to separate each level (like |):

Let’s say you send this string from your php script: Level One&Testing this thing2.5|Level Two&Another test3.0

Then use String.Split to split the string on the | to get an array of strings. Then, for each string, split on to get the fields. You should get a string array with 3 elements for each level.

You might check this link out: String.Split problem - Questions & Answers - Unity Discussions for using split in JS.

This seems like it could just work… I never heard of the split function. Thanks man, I’ll try it out.

EDIT: Using a JSON Parser to get it to do what I wanted!
