[英]Gallery Is Missing Files From Directory- How To Retrieve All Files From Directory
我终于有了使用fancybox时从目录填充图库的代码。 这是一个基本的缩略图库,单击后会显示较大的图像。 唯一的问题是缩略图目录中缺少很多文件。
该代码将检索较大图像的所有链接,但不会检索所有缩略图,仅检索其中的一部分,它们甚至不按顺序排列。
我的代码有什么问题?
<?php
$directory = 'thumb'; //where the gallery thumbnail images are located
$allowed_types=array('jpg','jpeg','gif','png');//allowed image types
$file_parts=array(); $ext=''; $title=''; $i=0;//try to open the directory
$dir_handle = @opendir($directory) or die("There is an error with your image directory!");
while ($file = readdir($dir_handle)) //traverse through the files
{ if($file=='.' || $file == '..') continue; //skip links to the current and parent directories
$file_parts = explode('.',$file); //split the file name and put each part in an array
$ext = strtolower(array_pop($file_parts)); //the last element is the extension
$title = implode('.',$file_parts); //once the extension has been popped out, all that is left is the filename
$title = htmlspecialchars($title); //make the filename html-safe to prevent potential security issues
natsort($file_parts); //sort by filename--NOT WORKING
$nomargin='';
if(in_array($ext,$allowed_types)) //check if the extension is an allowable type
{
if(($i+1)%4==0) $nomargin='nomargin'; //the last image on the row is assigned the CSS class "nomargin"
//Begin thumbs containers with fancybox class
echo '<div class="thumbs fancybox '.$nomargin.'" style="background:url('.$directory.'/'.$file.') no-repeat 50% 50%;"> <a rel="group"
href="images/'.$file.'" title="'.$title.'">'.$title.'</a>
</div>';
$i=0; //increment the image counter
} } closedir($dir_handle); //close the directory
?>
您可能想用来保护缩略图列表的另一种方法:
$directory = 'thumb'; //where the gallery thumbnail images are located
$files = glob($directory."/*.{jpg,jpeg,gif,png}", GLOB_BRACE);
natsort($files); //sort by filename
然后将其渲染出来,只需执行以下操作:
<?php
for($x = 0; $x < count($files); $x++):
$thumb = $files[$x];
$file = basename($thumb);
$nomargin = $x%4 == 0?" nomargin":"";
$title = htmlspecialchars($file);
?>
<div class="thumbs fancybox<?= $nomargin ?>"
style="background:url('<?= $thumb ?>') no-repeat 50% 50%;">
<a rel="group" href="images/'.<?= $file ?>" title="<?= $title ?>"><?= $title ?></a>
</div>
<?php
endfor;
