I’ve put together the following script which allows users to view their uploaded images in the original folder structure that they were saved.
UPDATED CODE
<?php session_start();
$_SESSION['username']=$_POST['username'];
$_SESSION['locationid']=$_POST['locationid'];
?>

I can correctly show the folders, but when I click on the folder to drill down to the individual images I receive the following error:
Warning: DOMDocument::load() [domdocument.load]: I/O warning : failed to load external entity "/homepages/2/d333603417/htdocs/development/UploadedFiles/files.xml" in /homepages/2/d333603417/htdocs/development/imagefolders.php on line 25 Warning: Invalid argument supplied for foreach() in /homepages/2/d333603417/htdocs/development/imagefolders.php on line 65
Line 25 is this line $descriptions->load($absGalleryPath . '/' . 'files.xml'); and line 65 is this:foreach ($items as $key => $value) {`
My initial script didn’t use session variables and I didn’t have any issues. However I now need to include these, so I’m sure that there is a conflict between these and the foreach command. I’ve done quite a bit of research to see if anyone else has had similar issues, but can’t find anything.
I just wondered whether someone could look at this and let me know where I’m gong wrong.
Many thanks and regards
Error 1
The Origin of the Problem is
$descriptions->load($absGalleryPath . '/' . 'files.xml');It is bad practice trying to load file you are not sure it exists or is readable
Something like this is better and make sure you catch exception
Error 2
A. Since you are not able to load the first
xmldocument … trying to continue the process would result to this errorB.
foreach ($items as $key => $value) {so it would run independently where it is populated or notC. Too many Referencing would make your code more difficult to understand and debug …
Conclusion
I think you should post the content of
files.xmlyou would be surprised it innovative solutions and ore effective code people would come up with
