Make your own PHP adoptables system

[MyGodLives]

Thanks Nick! I'm currently working on getting my pets up to snuff, but this helped a lot!

This is my new adoptable site. It's just using the main switch-your-animals-out approach, but heck, it works.

Hullo! Im new to this site!
i Need some help.
The 000 webhost is not working for me. can anybody recommend some others?

EDIT:
Heres my Code:

Code: Select all

<?php

//Tell the browser that we are sending it a PNG image to display
//header("Content-Type: image/png");

//Echo the contents of the image file called "Alex.png" to send it to the browser
//readfile("Alex.png");

?>

Im not sure whats wrong! Cause wHen i open firefox,(im using notepad++, and im trying to click on run, and then firefox)
nothing is showing up!!!!
Help!

That code does nothing, everything has been commented out by putting "//" at the start of the line. Please check the code from the tutorial pages again.

I have a problem with the codes in the tutorial.
The first code works, but when I extended the code to the baby rats, I get an error message that the code is flawed, and this error message I get when all of the following codes.

Paste the error message, and the line it refers to, here.

I have a problem with the codes in the tutorial.

I was just about to say that SAME thing, how ironic... I use 000webhost, and this is the message I get:

Code: Select all

<!-- www.000webhost.com Analytics Code -->
<script type="text/javascript" src="http://analytics.hosting24.com/count.php"></script>
<noscript><a href="http://www.hosting24.com/"><img src="http://analytics.hosting24.com/count.php" alt="web hosting" /></a></noscript>
<!-- End Of Code -->

You see, When I used this code:

Code: Select all

<?php

//Tell the browser that we are sending it a PNG image to display
header("Content-Type: image/png");

//Echo the contents of the image file called "dogbaby.png" to send it to the browser
readfile("dogbaby.png");

?>

dogbaby.png showed up JUST fine. I wasn't having any problems.

But once I uploaded new new simple.php and ratbaby, I got that error message (showed above).

Here is the code where the error message first started showing up:

Code: Select all

<?php

//Tell the browser that we are sending it a PNG image to display
header("Content-Type: image/png");

if ($_REQUEST['id']==1) {
    //Echo the contents of the image file called "dogbaby.png" to send it to the browser
    readfile("dogbaby.png");
} else if ($_REQUEST['id']==2) {
    //Echo the contents of the image file called "ratbaby.png" to send it to the browser
    readfile("ratbaby.png");
}

?>

And so that code, and any code I tried after it made that error message to show up.

I'm not sure what's going on here. =P

I'm not sure what's going on here. =P

P.S. - My site is here... not sure if you need it for reference or anything?

You're not using the right URL to view the image. As the text says, you need to view simple.php?id=1 or simple.php?id=2, not just simple.php.

Oh okay, thanks.

I tried that and it's fine now.

Okay, so I am setting up the adoptables system, and I have a problem when you adopt.

I got the mainpage.php up, but the problem is that when you adopt a "dog" or "rat", it takes you to the adopt.php page, but instead of showing the picture of the adoptable you adopted, it shows a box with a red "x".

The page is located HERE.

Here is my coding for the pages:

adopt.php

Code: Select all

<html>
<head>
</head>

<body>
<?php

require("adopttools.php");

/* Our visitor has picked an adoptable they want, its id is in $_REQUEST['id']. Find that
 * adoptable in adoptables.xml
 */
$adoptable=find_adoptable($_REQUEST['id']);

/* To randomly pick a variation from that adoptable, we're going have to do a little maths with
 * random numbers.
 *
 * First we find the sum of all the 'chance' attributes for this adoptable...
 */

$sum=0;
foreach ($adoptable->variation as $variation) {
    $sum=$sum + $variation['chance'];
}

/* Now we can generate a random number which goes from 0.0 to that sum. This will help us
 * pick a variation.
 */
$random=lcg_value()*$sum;

$sum=0;
foreach ($adoptable->variation as $variation) {
    $sum = $sum + $variation['chance'];
     
    if ($random <= $sum) {
        //Choose this variation
        $v_id=$variation['id'];
        break;
    }
}

?>

<p><img src="simple.php?a=<?php echo $_REQUEST['id'];?>&amp;v=<?php echo $v_id;?>"></p>
<p>Thanks for adopting this pet! :). Here is the adoption code for your pet:</p>
<p><textarea cols="60" rows="2"><img src="http://www.mywebsite.com/simple.php?a=<?php echo $_REQUEST['id'];?>&amp;v=<?php echo $v_id;?>"></textarea></p>
</body>
</html>

adopttools.php

Code: Select all

<?php

//Load the adoptables XML file
$adoptxml=simplexml_load_file("adoptables.xml");

//Find the adoptable from adoptables.xml which has the right id
function find_adoptable($id) {
    global $adoptxml;

    //For each 'adoptable' tag which is available
    foreach ($adoptxml->adoptable as $adoptable) {
     
        //Is this adoptable's id the same as the one that the user wants to see?
        if ($adoptable['id']==$id) {
            //Yes, it is
            return $adoptable;
        }
    }
     
    return NULL; //We couldn't find an adoptable with that ID
}

//Find the variation with the given adoptable id and variation id
function find_variation($adoptid, $varid) {

    $adoptable=find_adoptable($adoptid);

    //For each 'variation' tag which is available
    foreach ($adoptable->variation as $variation) {
     
        //Is this variation's id the same as the one that the user wants to see?
        if ($variation['id']==$varid) {
            //Yes, it is
            return $variation;
        }
    }
     
    return NULL; //We couldn't find the variation with that ID
}

?>

adoptables.php

Code: Select all

<adoptables>

<adoptable id="1">
    <variation id="1" chance="1.0">
        <age image="dogbaby.png" />
        <age date="2010-1-15" image="dogpuppyrare.png" />
        <age date="2010-1-16" image="dogadultrare.png" />
    </variation>
    <variation id="2" chance="5.0">
        <age image="dogbaby.png" />
        <age date="2010-1-14" image="dogpuppy.png" />
        <age date="2010-1-16" image="dogadult.png" />
    </variation>
</adoptable>

<adoptable id="2">
    <variation id="1" chance="1.0">
        <age image="ratbaby.png" />
        <age date="2010-1-15" image="ratadult.png" />
    </variation>
</adoptable>

</adoptables>

Thanks!


EDIT: Now for some reason I am getting a lot of error messages, here: CLICK, and Here: CLICK. mainpage.php is working fine, but those error messages show once you have "adopted" the pet.

Sorry for taking so much of your time with this!
