i want to be able to limit the $uploaded_files part to 10. but i dont have a clue how. And i want to use pagination but i dont have a mysql database in which i store the uploaded files. Any ideas how. I do have an uploaded log, but its in a .txt file. Any thoughts how?

anyone?

basically, you'll want to set a limit variable, ie. $limit = 10;

 

then, it all depends on how you will be storing the filenames, ie. in a database, file, etc...

 

i do like so .. i have a field in my db called files .. the file path(s) are imploded before they are inserted, like so, ie. filenameOne.txt|filenameTwo.txt, etc...

 

then, they are extracted and counted, then checked against the $limit var.

 

ultimately, there is a lot more that goes into this, but that's an idea.

yes but i dont have a db. i have a log in which i keep all of the uploaded files names, date of upload and time of upload. i don't know how i would limit it from the log...
