A new adventure with every line i type. How to create an photoscript which works?

[ajdegans]

Allright, ive been learning PHP for some days now starting with blank files, MM dreamweaver, open minded and a lot of food and drinks next to me 😃

Also i had set up a server from which i ran scripts from hotscripts.com and such for some months now 🙂
(Now its my dedicated test server)

Anyway let get to the topic... In earlier posts i tried to make an allround emailform and i (read: WE) succeeded thanks to the forum here!

Now im working on a photoalbum thing, again it must be real simple and basic no fancy stuff just showing photos...

I already created an thing to do that! but here's the problem!

When i open a photo it opens in a new blank screen showing the photo. Now my idea is to create something like it only WITH it must open in an new page. showing the picture and an BACK button 🙂 kind of an problem since i hardly know PHP and dont know where to start 🙁

here's my script so far:

<?
include ('./includes/opmaak.php');

$maxline="2";
$_list_path = "fotos" . "/";

echo "<center><table align='center' border='$fborder' bordercolor='$ftcolor' bgcolor='$fbgcolor' width='75%'>";

$dir = opendir($_list_path);
$x=1;

echo "<tr>";

 while ($file = readdir($dir)) {
  if ($file == "index.php") continue;
  list ($s1,$s2) = split ('[.]', $file);
  if (!$_show_dots_dirs && $file == "." || $file == "..") continue;
  $fullfile = "$_list_path$file";
  if (!is_dir($fullfile)) {
 if (($s2 == "JPG") || ($s2 == "GIF") || ($s2 == "PNG") ) {

echo "<td align='center' width='50%' bordercolor='$fccolor'><font size='2'>";
// echo "<a href='$_list_path$file'>$file</a><br>";
echo "<a href='$_list_path$file'><img src='$_list_path$file' height='125' width='100' border='1'></a>";
echo "</font></td>";

} else {

echo "<td align='center' width='50%' bordercolor='$fccolor'><font size='2'>";
// echo "<a href='$_list_path$file'>$file</a><br>";
echo "<a href='$_list_path$file'><img src='$_list_path$file' height='125' width='100' border='1'></a>";
echo "</font></td>";

}
if ( $x == $maxline ) {

echo "</tr><tr>";

$x=0;
}
$x++;
 }
}

echo "</tr>";
echo "</table></center>";

?>

the include() command on top refers to opmaak.php. opmaak.php holds the theming or template or whatever you want to call it... Alomst every value, array is in the script itself... so no additional files this time, only for the templating...! :p

Does anyone have an idea how to pull this off ? 🙂

Thanks in advance!

YOU CRACK ME UP! :-D I will be looking tomorrow at your thing. Then I will be able to give you a good idea of what to do. Also check your private messages. I wrote you. 🙂

Chad

[ajdegans]

Thanks for looking at my code. I really hope you can help 😉 Still i have no clue what to make of it 🙁

I've read your private message and replied to that aswell! 😃 😃

[chads2k2]

Sorry took me a while to get back to you. This code is by no means clean. However it works. You can see a working model at :

http://24.33.232.23/phpbuilder/trial.php

The source behind:

<?php
$i = 0;
$dir = "../funnypics/";

// Open a known directory, and proceed to read its contents
if (is_dir($dir)) {
   if ($dh = opendir($dir)) {
       while (($file = readdir($dh)) !== false) {
           $given_array[$i] = "$dir$file";
           $i++;
       }
       closedir($dh);
   }
}
// IF YOU FIND THAT IT PULLS OUT ONE MORE IMAGE THAN YOU LIKE.  THEN DECREASE $i.
$i--;
// MINE WAS OFF.
/* Starting with 2 because the dir does this:
*
* .
* ..
*
* Let's just cut out those two right?  They are in an array ... easily done. :)
* PLEASE read what the for loop does (if you don't know)
*
*/
function listall($i,$given_array)
{
         for($ii=2;$ii<=$i;$ii++)
         {
              echo "<img src='$given_array[$ii]' height='50' width='50'> <br>";
         }
}
if(!isset($function))
{
   $currentimage = "$given_array[2]";
   $display_num = 2;
}
if($function == 1)
{
	$counter--;
	$currentimage = "$given_array[$counter]";
	$display_num = "$counter";
}
if($function == 2)
{
	$counter++;
	$currentimage = "$given_array[$counter]";
	$display_num = "$counter";
}
?>
<html>
<body>
<table width="564" border="0" cellpadding="0" cellspacing="0">
  <tr>
    <td width="20" height="272">&nbsp;</td>
    <td width="477" valign="top"><div align="center">


<img src="<?php echo "$currentimage"; ?>" width="347" height="292">
<div align="center">

<?php
	// THIS WILL END THE FORWARD AND BACK BUTTONS WHEN THE ARRAY IS OVER.

// TAKES OUT THE BACK BUTTON.
if($counter>2)
{
echo "<span class='style3'><a href='trial.php?function=1&counter=$counter'><--</a></span>&nbsp;&nbsp;";
   }

// TAKES OUT THE NEXT BUTTON.
if($counter<$i)
{
	echo "&nbsp;&nbsp;<span class='style3'><a href='trial.php?function=2&counter=$counter'>--></a></span>";
}
?>


</div>
    </div></td>
    <td width="67" valign="top">
    <?php listall($i,$given_array); ?>
    </td>
  </tr>
</table>
</body>
</html>

Like I said it's not clean but the core functions are there. Mine takes a bit to initialize. I would recommend that you put all your images into one directory and then define that directory. That is the best way to do it. You don't have to search for PNG's, JPG's, or GIFs. It does whatever is in that file and tries to display it. I hope this helped you out some. It made me learn more about the directory functions that are built in. They are pretty darn cool. Keep going man your doing great! Chug along.

[ajdegans]

Thank you soo much 🙂

Im gonna try and get it working right away... ill keep you posted 😃😃

[ajdegans]

Why do the nav buttons not work when i copypaste the script into my own trial.php? i can see the pictures, even the thumbnails 😃 but when i click the next button nothing happens 🙁

[chads2k2]

Hey if you feel comfortable would you give me the FTP username and password and I can figure out why the counter didn't go through. I will work on another form of code I think I might now where the breakdown is. I will work on it and re-release it. Keep working, your doing well. Any questions about the code let me know.

Chad

[ajdegans]

where do you think the break is then?? maybe i can fix it with some tips... learning as i go! 😉

[chads2k2]

Has to be with the if's... where the link is displayed. That is the only thing I could think of ... I need to take a nap (work sucked today) then I will get coding.

Chad

[ajdegans]

lol if we get this thing working ill put your name in the ending product 😛 anyway... why is it working on your site and not on mine?😕

[chads2k2]

That is what I am saying ... PM with your username and password to your FTP site. I will check your code from the website and see what and why the directories aren't making sense. Just doesn't make any sense to me really. Let me know and thank you for the name thing. That would be great!

Chad

[ajdegans]

ill send u a msg with login specs😃

but keep in mind when changing things... the script MUST work on everyone's server, not only mine :eek:

[chads2k2]

Found the hole. I never defined $counter off the inital run. That would cause a invalid state in the diagram.

Here is the final code.

<?php
$i = 0;
$dir = "../funnypics/";

// Open a known directory, and proceed to read its contents
if (is_dir($dir)) {
   if ($dh = opendir($dir)) {
       while (($file = readdir($dh)) !== false) {
           $given_array[$i] = "$dir$file";
           $i++;
       }
       closedir($dh);
   }
}
// IF YOU FIND THAT IT PULLS OUT ONE MORE IMAGE THAN YOU LIKE.  THEN DECREASE $i.
$i--;
// MINE WAS OFF.
/* Starting with 2 because the dir does this:
*
* .
* ..
*
* Let's just cut out those two right?  They are in an array ... easily done. :)
* PLEASE read what the for loop does (if you don't know)
*
*/
function listall($i,$given_array)
{
         for($ii=2;$ii<=$i;$ii++)
         {
              echo "<img src='$given_array[$ii]' height='50' width='50'> <br>";
         }
}
if(!isset($function))
{
   $currentimage = "$given_array[2]";
   $display_num = 2;
   $counter = 2;
}
if($function == 1)
{
	$counter--;
	$currentimage = "$given_array[$counter]";
	$display_num = "$counter";
}
if($function == 2)
{
	$counter++;
	$currentimage = "$given_array[$counter]";
	$display_num = "$counter";
}
?>
<html>
<body>
<table width="564" border="0" cellpadding="0" cellspacing="0">
  <tr>
    <td width="20" height="272">&nbsp;</td>
    <td width="477" valign="top"><div align="center">


<img src="<?php echo "$currentimage"; ?>" width="347" height="292">
<div align="center">

<?php
	// THIS WILL END THE FORWARD AND BACK BUTTONS WHEN THE ARRAY IS OVER.

// TAKES OUT THE BACK BUTTON.
if($counter>2)
{
echo "<span class='style3'><a href='trial.php?function=1&counter=$counter'><--</a></span>&nbsp;&nbsp;";
   }

   //TAKES OUT THE FORWARD BUTTON WHEN THE FORWARD BUTTON WHEN NO MORE ARE LEFT.
	if($counter<$i)
	{
		echo "&nbsp;&nbsp;<span class='style3'><a href='trial.php?function=2&counter=$counter'>--></a></span>";
	}
?>


</div>
    </div></td>
    <td width="67" valign="top">
    <?php listall($i,$given_array); ?>
    </td>
  </tr>
</table>
</body>
</html>

Let me know if that one works. It should.

Chad

[ajdegans]

it doesnt work...

see what it does: http://www.zerocom.ath.cx/scripts/trial.php?function=2&counter=2

I understand the counter is now defined and the number is in the url... but it doesnt go to the next picture...🙁

[ajdegans]

i think this is wrong code:

if(!isset($function)) 
{ 
   $currentimage = "$given_array[2]"; 
   $display_num = 2; 
   $counter = 1; 
} 

The counter string is defined wrong i think.... it i change it into something else i get the same as with the earlier script... yet i dont know what to make of it 😉 some sort of 'go to next pic' command i guess....😃

another thing... where is the $function sting defined?

[ajdegans]

alright the script works 🙂

i tried it on another server just a minute ago...

The second release works!

but not on my private server

wonders why :mad:

[chads2k2]

Well your PHP.ini file might not be working quite right. Yeah the $counter is defined right when there is not $function defined because it needs to tell what picture you are currently on. Yeah I don't know why it's not working on your private server. I have an idea that you want to change everything to $_POST['varname']; I think that is how it is. I never use that because I always turn global variables on. Just makes the coding easier for me. However people wouldn't hesistate to jump on this opportunity to prove someone wrong. 🙂

Yeah so that is great to hear that the second one works. I will try to re-write the coding using the "other" way. Maybe I will have my apprentice do it. That would be good for him. haha.

Chad

[ajdegans]

lol,

Well i will look into the $_post[varname] thing later... im glad already the script itself works good 🙂

one question though... how common is you configuration? as in would it work on only yours or on almost every server?😃 just for me whether it have to look into the script to config it so that it works always or that i just edit my php.ini for right usage!

Thanks alot. i WILL put your name into the end product or my web enviroment 😃

[chads2k2]

Thank you . Hey if you have AIM or anything like that please just IM me at chads2k2. I will be more than happy to talk with you. My configuration is pretty common that I know of. Every paid hosting as well as my own are setup similar to what I have running on my testing servers. I use my testing servers to mock the setup on the "real" server that I am migrating the scripts to. Just makes it easier.
