changing pics

[BillyBoB]

i have this code :

[code]
<?php
if($_GET['pic'])
{
$pic = $_GET['pic'];
echo(" <a href=\"viewpic.php?pic=$pic&full=y\" border = \"0\"><img src=\"halopics/$pic.jpg\" height=\"300\" width=\"490\" border = \"0\" /></a><br /><center>Click the Pic to Enlarge.</center><br />");
echo("<center><form method=\"POST\"><input type=\"submit\" name=\"back\" value=\"Back\" />\____/<input type=\"submit\" name=\"next\" value=\"Next\" /></form></center><br />");

$dir = './halopics/';
$handle = opendir($dir);

while (($file = readdir($handle)) !== false)
{
if ( !in_array($file, array('.', '..') ) )
{
$file_list[] = basename($file, '.jpg');
}
}

closedir($handle);

asort($file_list);
if($_POST['next'])
{

}
if($_POST['back'])
{

}
echo ("
<center><form method=\"POST\">Select:<select name=\"pic\">
");
foreach($file_list as $key => $value){
echo ("
<option>$value</option>
");
}
echo("
</select>
<input type=\"submit\" name=\"submit\" value=\"View Pic\" />
</form></center>
");
if($_POST['submit'])
{
$pic = $_POST['pic'];
echo("<meta http-equiv=\"Refresh\" content=\"0; URL=http://dreamshowstudios.net/viewpic.php?pic=$pic\"/>");
}
}else{
$dir = './halopics/';
$handle = opendir($dir);
while (($file = readdir($handle)) !== false)
{
if ( !in_array($file, array('.', '..') ) )
{
$file_list[] = basename($file, '.jpg');
}
}

closedir($handle);

asort($file_list);
echo ("
<center><form method=\"POST\">Select:<select name=\"pic\">
");
foreach($file_list as $key => $value){
echo ("
<option>$value</option>
");
}
echo("
</select>
<input type=\"submit\" name=\"submit\" value=\"View Pic\" />
</form></center>
");
if($_POST['submit'])
{
$pic = $_POST['pic'];
echo("<meta http-equiv=\"Refresh\" content=\"0; URL=http://dreamshowstudios.net/viewpic.php?pic=$pic\"/>");
}
}
?>
[/code]

heres the link to see it in action [url=http://dreamshowstudios.net/viewpic.php]http://dreamshowstudios.net/viewpic.php[/url]

i need the next and back buttons to scroll through the pics
is there a way to do this with the above array?

Not sure if this will help, but its an album that uses a flat file rather than a database. The pic urls & names are placed into an array (much like you are doing with readdir).

You probably could adapt the pagination portions to do what you want.

I disabled the add/edit/delete functions as it is the View portion that is pertinent

here is the link to a zip file that contains ALL of the scripts.

thats not exactly wat im looking for im looking for a script to make it where when next is hit then it takes the position of the pic and then changes the name to the next pic in the array

[BillyBoB]

all my names have the same amount of letters it goes a-pic-(0-9) and b-pic-(0-9) (without the () ) and so on

is there a way to start reading a array from a certain point then skip this many letters then save this many and ignore the rest ?

Check out this file browser:

You could use it's image viewing code as an example for tracking previous, current and next pictures.

Good luck!  ;)
