Fetch image from folder via datatable does not work after placing image in subdirectory
- by Arnold Bishkoff
I am having trouble wrapping my head around the following
I have code that fetches an image via smarty in a line
img src="getsnap.php?picid={$data[$smarty.section.sec.index].picno|default:$nextpic}&typ=pic&width={$config.disp_snap_width}&height={$config.disp_snap_height}" class="smallpic" alt="" /
this works if i pull the image from /temp/userimages/userid/imageNo.ext
but because an OS can segfault if you store too many folders or images in a directory
i have code that assigns the user image to a subdirectory based upon division of a subdir per 1000 userids. so in thise case i have user id 94 whos images get stored in /siteroot/temp/userimages/000000/94/pic_1.jpg (through 10) or tn_1 (through 10).jpg
here is the code for getsnap.php
<?php
