Cron Job

[th1982]

I have a question :
I m using window host and i dont have either cronjob function and schedule task (i asked host provider ,they said they donnot have it)
So have any scripts(php,jav ascript....) to do this work(running a file on server with specific time)?
Thanks so much.

In a word no. You see, php, javascript, html etc are all only "run" when they are called. So when a user goes there is one of two ways it can be called. The second way is if a server automatically runs it. This is usually done with cronjobs and is really what you need.

May I ask which provider you're with?

What does the file do that you want to run in a cronjob? Maybe there is a way around it?

yes there is.

from a computer that has internet access around the time you want to run it, and do a scheduled task/cron job that calls a PHP file that does exactly that.

Good luck.

I think that's what we're talking about? But yeah, if your provider doesn't offer it, you will need to schedule it on your own computer and so it has to be on. If it is only once a day, this isn't too big a task. A lot of mine (will) run every 10mins, so it's really impossible for me to use that option.

Actually, I have thought of another way. It's a little fiddley, but it should work. What you is you have a small bit of code at login (or a common page) that checks the time against when the last time your file was run. So you need to have another MySQL table which just stores the last time it was run.

When the user (anyone) goes to your site and logs in, a bit of code will run and check if the current time is over 24 hours from the last run time. If it is, it will execute that file and do what you want. If not, it will continue as normal.

I know it's probably been done before, but I've never heard of it, so for the next 5mins we will pretend that I am a genius ;)

What if noone visits the page for months?

OR EVEN YEARS?!

I don't believe it's too hard to, on your own pc, use windows schedule task manager.

Hi!
In your schedule you'll need to specify an application or a script that does the task of calling your remote script url.
You could for example call a web browser with the url as argument. A more elegant alternative would be to write a VB script to call the url. An example VB script can be as follows:

'scriptfile.vbs
Call LogEntry()
Sub LogEntry()
        On Error Resume Next
        Dim objRequest
        Dim URL
        Set objRequest = CreateObject("Microsoft.XMLHTTP")
        URL = "http://YOUR-URL"
        objRequest.open "POST", URL , false
        objRequest.Send
        Set objRequest = Nothing
End Sub

Hope this could be of help.

Just open your task scheduler, then select your internet browser as the action (giving the url of your script as an extra argument).
