this program has been annoying me for some time, its pretty much the first thing i have attempted to do in perl. its a pretty simple guestbook type thing. it all works ok in that it saves all the newest information to a log file. however in falls down in the whole putting-the-old-data-back part. which is really quite a desirable function in my script.
at the moment i have only four fields. the script is supposed to read the old data into an array, print the new data into the log file, then print the old data back after it, keeping the newest entries at the start of the file. eventually i plan to print the entries in all formatted in html then just use an ssi to paste the log file into another page. anyway! the script reads something out of the log file, and prints the new fields in no problem, however it only prints in the first line of the previous log file.
so the log file only ever has 5 lines really.
i have read asmany pages of perl documentation i can handle without breaking something, and they al seem to be telling me to do what i allready have.
i have checked my server error log and nothing shows up. so its not really an error, just my code doing the rong thing.
well here it is
