Can anyone help me?

probably because you haven't set this variable " $_POST[txtsearchAdmin] "

you have all the errors turned on, but i don't think there is an issue, does your coed work though?

i'm no expert but i get these errors because i don't declare variable before hand, but the code still works.

nakamurakazuma

my code work and nothing wrong.
but there's an error like that @__@

i think you haven't declared the variable before the form you have placed.

might be worth adding a function to do a check to see if variables are set?

I normally create class files for each function so that when something is posted it goes to class and then comes back to the same page, that way i get to re-use the class elsewhere.

i think that makes sense 🙂

Well just use isset() or empty() to check these variables you submit through forms, this will get rid of notice errors. I have such kind of problems too before I enabled notice error on my server. It wont make a difference if you are building a site of your own, but for software programmers its somewhat unprofessional.

i second that, i managed to fill a log with about 1gb of these types of errors. but i soon got it out of my system 🙂

Lord_Yggdrasill

Wow 1gb of error messages? Thats a lot, you must've ignored them for a long long time that they aggregates to that extent. XD

Anyway I usually prefer using !empty($POST['var']) for form validation since it does everything isset() does, plus it checks if the variable is not empty. Of course there are times when isset does a better job.

Damian_

yeah i did ignore them. I test everything like a thousand times.. i rarely let anything go out to my boss, i hate it when he finds errors hehe.
