Directory thumbnail links

music_man

I found a spoono tutorial about opening image directories and thought I could have a script which opened a thumbnail directory and displayed the thumbnail and link to the main picture. The thumbnail directory is inside the main images folder.

It is not working for some reason.

<?

// define paths

$directory = "test";

$pathrelthumb = "/path/to/$directory/thumbnails";

$paththumb = "http://url/to/$directory/thumbnails";

$pathbig = "/path/to/$directory";

// big processing

$dir_handlebig = @opendir($pathbig) or die("Unable to open $pathbig");

while ($filebig = readdir($dir_handlebig)) 

{

$filebig = $filelink;  

}

closedir($dir_handlebig);


// main processing

$dir_handlerelthumb = @opendir($pathrelthumb) or die("Unable to open $pathrelthumb");

while ($filethumb = readdir($dir_handlerelthumb)) 
{

   if($filethumb!="." && $filethumb!=".." && $filethumb!="chart.jpg")

// I would like to exclude the file "chart.jpg"from the file listing

  echo "<a href='$pathbig/$filelink'><img src=\"$paththumb/$filethumb\" /></a>&nbsp;";
}

// close thumb directory

closedir($dir_handlerelthumb);

?>

I would have liked an automatic 25% aspect ratio thumbnailer but the tutorials I found were difficult to follow.

Thanks

Solved this:

<?



// define paths

$directory = "images";

$pathrelthumb = "/path/to/$directory/thumbnails";

$paththumb = "http://path/to/$directory/thumbnails";

$pathrelbig = "/path/to/$directory";

$pathbig = "http://path/to/$directory";

// main processing

$dir_handlerelbig = @opendir($pathrelbig) or die("Unable to open $pathrelbig");

$dir_handlerelthumb = @opendir($pathrelthumb) or die("Unable to open $pathrelthumb");

while (($filethumb = readdir($dir_handlerelthumb)) && ($filebig = readdir($dir_handlerelbig))) 

{

   if($filethumb!="." && $filethumb!="..")
      echo "<a href='$pathbig/$filebig'><img src=\"$paththumb/$filethumb\" /></a>&nbsp;";
}

// close thumb directory

closedir($dir_handlerelbig);
closedir($dir_handlerelthumb);

?> 

<? break;


}


?>

Are there any shortcuts / glaring security problems here?

I have downloaded and modified a little simple easy thumbnail script.

you set a variable for any percent % size

See my OPENFILES php scripts:
http://213.100.118.115/openfiles/index.php

look in directory thumbsup

😉 halojoy at phpbuilder again 😉

I was wondering on how I could make it so if the number of thumbnails reached e.g. 4 then it could add a break.

Is this using the count string?

Also another bug came up - I had "chart.jpg" in the normal image directory and not in the thumbnail directory and the link went wrong - the first link went to chart.jpg.

so how did you like my little thumbsup script?

I prefer to make my own code with help from tutorials and books rather than using premade scripts. Thank you for the link nonetheless.

I was thinking of putting the output into a string array then having something that for every 4th image it adds a break. I don't know how to do this. Are there any links that show converting this variable into an array?
