php - 画廊分页错误

Question

我已经根据我的需要调整了一个简单的分页画廊，但它并没有按预期工作：通常它会很好地放置第一“页”图片然后在某些情况下它只是跳过一些图片然后转到更多图片，在其他情况下情况下它只是不加载任何其他页面（我使用的是无限滚动）

这是php函数：

function makeGallery($path, $directory, $seo){
$dir = $path . "/" . $directory;
$handle = opendir($dir);
while ($file = readdir($handle)){
    if($file == '.' OR $file == '..' or $file == 'thumbs' or $file == '.DS_Store')
        continue;
    else
        $result_array[]=$file;
}

$filecount = count(glob("" . $dir . "*.jpg"));

closedir($handle);
array_multisort($result_array, SORT_ASC);
$rows = 3;
$cols = 8;

if(isset($_GET['page'])){
    $page = $_GET['page'];
}else{
    $page = 0;
}

$num_pics = count($result_array);
$cells = $rows * $cols;
$pages = ceil($num_pics / $cells);
$num_pages = $pages - 1;
$output = array();
$slices = array();
$push = 0;
$showpage = $page + 1;

for($k=0;$k<$pages;$k++){
    array_push($slices, $push);
    $push = $push + $cells;
}

for($k=0;$k<$pages;$k++){
    if($page == key($slices)){
        $output = array_slice($result_array, current($slices), $cells);
    }
    next($slices);
}

reset($output);
print '<div class="container-fluid">
    <div class="row">';
print "<ul id='photoswipe'  class='thumbnails'>";

for($i=0;$i<$rows;$i++){
    for($j=0;$j<$cols;$j++){
        if(current($output) != false){
            $value = current($output);
            $parts = Explode('.', $value);
        $title = $parts[count($parts) - 2];
        $parts = Explode('-', $title);
        $title = $parts[1];
        if ($title == "") $title = $value;
            print "<li class='box'><a title='$title' rel='group' class='thumbnails' href='$dir/$value'><img width='$width' height='inherrit' src='$dir/thumbs/$seo-$value' /></a></li>";
            next($output);
        }else{
            print "</ul>";
        }
    }
}


$ref = $_SERVER['PHP_SELF'];

if($num_pages == '0'){
    print " ";
    print " ";
}elseif(($page == '0')||($page == '')){
    $next = $page + 1;
    print " ";
    print "<a id='next' href='$ref?page=$next'> </a>";
}elseif($page == $num_pages){
    $prev = $page - 1;
    print "<a id='prev' href='$ref?page=$prev'> </a>";
    print " ";
}else{
    $next = $page + 1;
    $prev = $page - 1;
    print "<a id='prev' href='$ref?page=$prev'> </a>";
    print "<a id='next' href='$ref?page=$next'> </a>";
}

echo "<nav id='page-nav'>
<a href='$ref?page=$next'></a>
</nav></div></div>";
}

我确信应该有一些我没有发现的愚蠢错误，我希望一些有经验的 php 程序员可以很容易地找到它。

您可以在http://eikonabox.com/page/portrait.php上看到画廊（及其问题） （在肖像画廊中，您可以看到它从 24 号直接跳到 49 号）

谢谢你们

如果有人陷入这种问题，我已经通过这种方式解决了：

    function makeGallery($path, $directory, $seo){
$dir = $path . "/" . $directory;

$filearray = array(); 
if ($fil = opendir($dir)) {
    while (($file = readdir($fil)) !== false) {
        if ($file != "." && $file != ".." && $file != "thumbs" && $file != ".DS_Store") { 
            $filearray[] = $file;
            $page = empty($_GET['page']) ? 1 : $_GET['page'];
            $num_per_page = 25;
            $total_pages = ceil(count($filearray)/$num_per_page);
        }
    }

array_multisort($filearray, SORT_ASC);

print '<div class="container-fluid">
    <div class="row">';
print "<ul id='photoswipe'  class='thumbnails'>";

for($i = ($page - 1) * $num_per_page; $i < $page * $num_per_page; $i++){
            $value = basename($filearray[$i]);
            $parts = Explode('.', $value);
        $title = $parts[count($parts) - 2];
        $parts = Explode('-', $title);
        $title = $parts[1];
        if ($title == "") $title = $value;
        if($value != "")
                print "<li class='box'><a title='$title' rel='group' class='thumbnails' href='$dir/$value'><img width='$width' height='inherrit' src='$dir/thumbs/$seo-$value' /></a></li>";
}
closedir($fil);
}

print "</ul>";

$ref = $_SERVER['PHP_SELF'];

if($num_pages == '0'){
    print " ";
    print " ";
}elseif(($page == '0')||($page == '')){
    $next = $page + 1;
    print " ";
    print "<a id='next' href='$ref?page=$next'> </a>";
}elseif($page == $num_pages){
    $prev = $page - 1;
    print "<a id='prev' href='$ref?page=$prev'> </a>";
    print " ";
}else{
    $next = $page + 1;
    $prev = $page - 1;
    print "<a id='prev' href='$ref?page=$prev'> </a>";
    print "<a id='next' href='$ref?page=$next'> </a>";
}

echo "<nav id='page-nav'>
<a href='$ref?page=$next'></a>
</nav></div></div>";
    }
