Display Category Title once

[busnut]

Continuing on from another thread i've made about my photo gallery, I thought I would make a new one as i've pretty much got a working version, except I can't get the category to display just once. It either doesn't show at all or shows the category for each photo depending on where I locate the echo H2 reference.

 

So what i'm wanting is this:

category

image image image etc

next category

image image image etc

next category

image image image etc

 

Here is the script:

 

$dir = "gallery";
$text = "gallery.txt";
$cols = 3;
$colswidth = 33;
$fh=fopen($text, "r"); 

while(!feof($fh)) 
{ 
  $temp = explode("|", $line); 
  $title[$temp[0]] = $temp[1];
  $description[$temp[0]] = $temp[2];
  $photographer[$temp[0]] = $temp[3];
  $category[$temp[0]] = $temp[4];
  $line=fgets($fh); 
  unset($temp); 
} 

function ListFiles($dir) {

    if($dh = opendir($dir)) {

        $files = Array();
        $inner_files = Array();

        while($file = readdir($dh)) {
            if($file != "." && $file != ".." && $file[0] != '.') {
                if(is_dir($dir . "/" . $file)) {
                  echo "<h2>$category[$file]</h2><p>";
                    $inner_files = ListFiles($dir . "/" . $file);
                   if(is_array($inner_files)) $files = array_merge($files, $inner_files); 
               } else {
                    array_push($files, $dir . "/" . $file);
                }
            }
        }
        closedir($dh);
        return $files;
    }
}

foreach (ListFiles($dir) as $key=>$file){

      if (preg_match("/.jpg/", $file)) {

    echo "<a href=\"$file\" rel=\"lightbox\" title=\"$title[$file]<br>$description[$file]<br>© $photographer[$file]\"><img src=\"gallery-thumbnail.php?file=$file\">";
} 

}

Some thing like this

 

   if($dh = opendir($dir)) 
   {
        $last_cat = '';
        $files = Array();
        $inner_files = Array();
        while($file = readdir($dh)) 
        {
            if($file != "." && $file != ".." && $file[0] != '.') 
           {
                if(is_dir($dir . "/" . $file)) 
               {
                    if($last_cat != $categpry[$file])
                    {
                           echo "<h2>$category[$file]</h2><p>";
                           $last_cat = $category[$file];
                    }
                    $inner_files = ListFiles($dir . "/" . $file);
                    if(is_array($inner_files)) $files = array_merge($files, $inner_files); 
               } 
               else 
              {
                     array_push($files, $dir . "/" . $file);
               }
         }
    }
        closedir($dh);
        return $files;
    }

unfortuneatly it still isn't displaying the category. I've put the <h2> line in every position possible, with only down below the 'foreach' statement does it show the category, but shows it for every image

[jl5501]

I notice there is a typo in my code in the spelling of category

that might be the issue

didn't notice that myself, so i've changed that, still no luck sorry

Got it working, FINALLY. Thanks to jl5501 for the snippet of code, instead of just moving the <h2> line, i've moved the whole bit about if last cat section to below the foreach statement.

 

Attached is the code:

 

gallery.php

<h1>Photo Gallery</h1>

<? 
$dir = "gallery";
$text = "gallery.txt";
$cols = 3;
$colswidth = 33;
$fh=fopen($text, "r"); 

while(!feof($fh)) 
{ 
  $temp = explode("|", $line); 
  $title[$temp[0]] = $temp[1];
  $description[$temp[0]] = $temp[2];
  $photographer[$temp[0]] = $temp[3];
  $category[$temp[0]] = $temp[4];
  $line=fgets($fh); 
  unset($temp); 
} 

function ListFiles($dir) {

   if($dh = opendir($dir)) 
   {
        $last_cat = '';
        $files = Array();
        $inner_files = Array();
        while($file = readdir($dh)) 
        {
            if($file != "." && $file != ".." && $file[0] != '.') 
           {
                if(is_dir($dir . "/" . $file)) 
               {
                    $inner_files = ListFiles($dir . "/" . $file);
                    if(is_array($inner_files)) $files = array_merge($files, $inner_files); 
               } 
               else 
              {
                     array_push($files, $dir . "/" . $file);
               }
         }
    }
        closedir($dh);
        return $files;
    }
}

foreach (ListFiles($dir) as $key=>$file){

      if (preg_match("/.jpg/", $file)) {
                    if($last_cat != $category[$file] && $category[$file]<>"")
                    {
                           echo "<h2>$category[$file]</h2>";
                           $last_cat = $category[$file];
                    }

    if ($title[$file]<>"") { echo "<a href=\"$file\" rel=\"lightbox\" title=\"$title[$file]<br>$description[$file]<br>© $photographer[$file]\"><img src=\"gallery-thumbs.php?file=$file\" height='100' width='150'></a> "; } else 
echo "<a href=\"$file\" rel=\"lightbox\"><img src=\"gallery-thumbs.php?file=$file\" height='100' width='150'></a> ";
} 
} 
  
?>

 

gallery-thumbs.php

<?php
// define directory path
$image = exif_thumbnail($_GET['file']);
header("Content-Type: image/jpeg");
echo $image;
?> 

 

And then with the description text file, upload it to the same directory as the gallery.php & gallery-thumbs.php directory in this format:

gallery/subfolder name/file name.jpg|title|description|copyright|category

 

And remember to upload your images under the 'gallery' folder then in their subfolders.

 

then to get the lightbox working, download lightbox (search google) and implement some css to go with it.

 

Thanks once again
