Need help calling another script

[aileron]

Hi,

I have a form that calls a php script when a user has filled in information and hits the submit button. 

After the php script is done entering data into the database from the html form I would like it to call another script and pass just one variable to the script.

How would I do that with php?

I cant seem to find any examples of calling scripts within php after the script has been called from a form. I can't use include or require because the script im trying to call is already self contained and used elsewhere, it only needs one variable.

I think there's a function called exec() which you can use to execute any command you could use in from a shell. You could call a script that way, maybe something like this?

exec("/home/aileron/bin/myscript " . $vartopass);

I'm not sure exactly how exec works, maybe not exactly like this but you get the idea.

Now if you want to call another PHP script as opposed to a shell script or Perl script, I think you'd probably have to have the PHP executable to run it since I don't think you could use the Apache module.

I'm not sure though, but look up the syntax and usage for things like exec() which will probably be basically what you need.

the old-fashioned style is a http-refresh...

<meta http-equiv="refresh" content="0; URL=script.php?action=whattodo&parameter=<?=$parameter?>">

Why not build the form submission handler into the script you want to call?

Set the form action to "myotherscript.php", include a hidden field such that the event handler in the script can be triggered:
in the form -
<input type="hidden" name="activate" value="yes">

Then as your event handler (make this the first element of myotherscript.php:

if (isset($activate)) {
if ($activate == "yes") {
do DB stuff
generate value to pass through
} else {
echo "Why are you screwing around with my app?";
}; // END if ($activate == "yes")
}; // END if (isset($activate))

Once a page has done its processing, you can use header to go on to a new page. It might look something like this:

# process form variables....db inserts, etc...
#
#
header("Location:  new.place.com/new.php?passedvar=$passedvar");
exit;
#
#

Note: it is important to not send any output to the browser before you call header. Also, the exit is important because PHP will keep executing any php code after the header unless you use it. (This is a trivial example obviously, but in many cases you will have code after the exit, particularly if the exit is within some sort of conditional loop.)

Thanks a lot everyone, I am amazed at how fast you all responded. I'll be looking into these withing an hour and hopefully it will work for me.

You guys are awsome. 🙂
