And you might consider following the directions in the last part of the tutorial and renaming your adoptables XML file to something a little harder to guess..

I understand everything except for one thing, how do I enter these into a website? I
I am having huge issues with this <3.
Thanks in advance!

It's not a good idea to attempt this tutorial unless you have a very good grasp of building HTML websites. This includes using FTP or some other tool to upload files into your webhost. The details of doing this depend entirely on where you are hosted.

You might be more comfortable building a website here instead:

Thanks so much for the reply!
I think I understand now.

So I uploaded the XML file and it looks fine. There is just one thing, when I try to open the page it says:
The XML page cannot be displayed
Cannot view XML input using style sheet. Please correct the error and then click the Refresh button, or try again later.

--------------------------------------------------------------------------------

XML document must have a top level element. Error processing resource 'http://paekas.net16.net/test5.xml'.

I understand that you should just see the script from what I understand.

I uploaded my image, PHP script, and xml script.

Thanks!

There's probably something wrong with your XML script, but I can't fix it if I can't see it. You might want to PM me a link to it.

Having an issue with part 4 of the tut.
I have had all the previous parts working but I can not get the image of the adoption that the user picked to display on the "thank you for adopting" page.
It tries to load the image then just stops and displays the rest of the text and the img src of the pet you adopted. when I view the page of the image its trying to load it gives me this error.
The image "xxx/simple1.php?a=1&v=2" can not be displayed, because it contains errors.
I have tired amending the location of the page requests in the code by adding "./" in fromt of the location and I have tried without and I get the same result each time. I have reenamed the pages a bit since I am testing such as adoptables1.xml and simple1.php but I have also changed the calles to be correct in the other files.
heres the pages i have so far. I have edited out the site address with xxx as my site is not publicly open yet.
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="http://xxx.com/simple1.php?a=<?php echo $_REQUEST['id'];?>&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://xxx.com/simple1.php?a=<?php echo $_REQUEST['id'];?>&v=<?php echo $v_id;?>"></textarea></p> </body> </html>

adoptables1.xml

Code: Select all: <adoptables> <adoptable id="1"> <variation id="1" chance="1.0"> <age image="./dogbaby.png" /> <age date="2009-10-21" image="./dogpuppyrare.png" /> <age date="2009-10-22" image="./dogadultrare.png" /> </variation> <variation id="2" chance="5.0"> <age image="./dogbaby.png" /> <age date="2009-10-21" image="./dogpuppy.png" /> <age date="2009-10-22" image="./dogadult.png" /> </variation> </adoptable> <adoptable id="2"> <variation id="1" chance="1.0"> <age image="./ratbaby.png" /> <age date="2009-10-21" image="./ratadult.png" /> </variation> </adoptable> </adoptables>

adopttools.php

Code: Select all: <?php //Load the adoptables XML file $adoptxml=simplexml_load_file("./adoptables1.xml"); //Find the adoptable from adoptables.xml which has the right id function find_adoptable($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 } ?>

simple1.php

Code: Select all: <?php //Tell the browser that we are sending it a PNG image to display header("Content-Type: image/png"); require("./adopttools.php"); //Find the variation with the given adoptable id ('a') and variation id ('v') $variation=find_variation($_REQUEST['a'], $_REQUEST['v']); //Decide which of the ages we want to show for the adoptable $pickedAge=NULL; //We'll store the age we eventually pick into the variable $pickedAge /* Check the ages in order. The age we end up picking will be the last age * in the file where the current date is after the 'date' attribute */ foreach ($variation->age as $age) { if (!isset($age['date']) || time() > strtotime($age['date'])) { $pickedAge=$age; } } //Now that we've picked the age, display the image that that age uses readfile($pickedAge['image']); exit(); ?>

My html web page from my phpbb3 site i am incorporating this script with

Code: Select all:  <p class="{S_CONTENT_FLOW_END} rightside">{LAST_VISIT_DATE}{CURRENT_TIME}</p> <p>{CURRENT_TIME} <br />[ <a href="{U_MCP}">{L_MCP}</a> ]</p><p>{CURRENT_TIME}</p> <div class="panel"> <div class="inner"><span class="corners-top"><span></span></span> <div class="content"> <html> <head> </head> <body> <p>Adopt one of my pets!</p> <table width="400" border="0" cellspacing="0" cellpadding="4"> <tr> <td><img src="./dogbaby.png"></td> <td><a href="adopt.php?id=1">Adopt a dog!</a></td> </tr> <tr> <td><img src="./ratbaby.png"></td> <td><a href="adopt.php?id=2">Adopt a rat!</a></td> </tr> </table> </body> </html> </div> <span class="corners-bottom"><span></span></span></div> </div>

Please assist me with this if you could

Hm, I can't spot the problem. Likely, the image is starting out with a PHP error message, which is why your browser can't display it. Save the broken image to disk, and open it using notepad, that will allow you to read the error message within

.

You should also check that you don't have any spaces or newlines before the <?php or after the ?> of simple.php or adopttools.php.

Ok apparently that was the issue with a space at the end of the simple.php
Next question is there a tut or somewhere I can look to incorporate this with database usage so I can attach adoptables to the users account ?
