I think what you mean is:
You have a load function in a javascript file that runs when the page loads. You want to run this function again without reloading the page? (I am psychic Poke tongue | ;-P

)

You have to call the function..... either with an event handler on some element on the page or you can use setTimeout to run it after a certain amount of time.

Hi everyone!

I've got the following:

function setup_event(elem, eventType, handler)
  {
    (elem.attachEvent ? elem.attachEvent("on" + eventType, handler) : ((elem.addEventListener) ? elem.addEventListener(eventType, handler, false) : false));
  }

  function detach_event(elem, eventType, handler)
  {
    (elem.detachEvent ? elem.detachEvent("on" + eventType, handler) : ((elem.removeEventListener) ? elem.removeEventListener(eventType, handler, false) : false));
  }

This works perfectly in all browsers.

Trying to "shorten" things:

function setup_event(elem, eventType, handler)
  {
    (elem.addEventListener || elem.attachEvent)((elem.attachEvent ? "on" : "") + eventType, handler, false);
  }

  function detach_event(elem, eventType, handler)
  {
    (elem.removeEventListener || elem.detachEvent)((elem.detachEvent ? "on" : "") + eventType, handler, false);
  }

This works in MS IE; in Forefox & Opera it doesn't. Why?

Can someone test this on php 4.46 under Linux?

The zip file of this is at http://gpssharing.com/cookie.zip.

The test is at

http://gpssharing.com/cookie.php

Run the prog, then refresh the page, so the cookies will be read after being set.

can you see the two cookies 'fred' and 'test'?

Works fine on 4.4.6 under windows and 4.4.4 under Linux

Thanks in advance.

document.cookie = 'test=hello world; path=/';

_COOKIE Array<br />";
print_r($_COOKIE);

echo "_COOKIE['test'] " . $_COOKIE["test"] . "<br />";
echo "_REQUEST['test'] " . $_REQUEST["test"] . "<br />";
echo "_SERVER['HTTP_COOKIE'] " . $_SERVER["HTTP_COOKIE"] . "<br />";
echo "";

//phpinfo();
?>

Want to bet!!!!

I just had a reply from my ISP,

I am noticing that this is being blocked by suhosin which is a new security modules that we have installed to help prevent exploits and to keep the servers being blacklisted.

It looks like one thing has been fixed, breaking something else!

Hopefully other will 'learn' from this, at least my ISP did check out my test prog and admit to the problem, and have given me a solution.

Have you contacted Stephan Esser? If not please give me the details of what went wrong and I'll let him know.

No I have not, who is he?

I have slightly modified the zip file on my site, to display the version no of PHP

So if you know this guy please forward this info, here is the contents of the email from my ISP

I am noticing that this is being blocked by suhosin which is a new security modules that we have installed to help prevent exploits and to keep the servers being blacklisted.

When I disable suhosin I see

_COOKIE Array
Array
(
[fred] => home less
[test] => hello world
)
_COOKIE['test'] hello world
_REQUEST['test'] hello world
_SERVER['HTTP_COOKIE'] fred=home+less; test=hello world

It appears that it is blocking the document.cookie setting. I am not showing any errors so I am going to contact the author of suhosin to see if they have any suggestions.

Bradml23-Mar-07 22:34

please try this script, unfortunately I do not have access to a running PHP 4 server right now.

setcookie('fred', 'home less', null, '/', null, null, false);

Stephan Esser is the man who found the PHP security response team and the Suhosin project.

Thanks, Google just beat you, I am looking at the forums now.

Unfortunately I can't really use setcookie on my site, as with all software I could re write my code, but as the ISP is chasing this up.

They have just got back to me with a work around, I am impressed.

Thanks for your reply, as I am sure you will agree software updates are real fun;)

From their email:-

We aren't willing to completely disable suhosin, but I have disabled the cookie encryption setting

It is very refreshing to have an ISP that actually looks into and 'fixes' problems

Bradml23-Mar-07 23:05

That is quite nice of them, however that is a very useful function of Suhosin...

The ISP is surfspeedy.com perhaps the level 3 support were bored and fancied a play? But I can't complain.

My LINUX skills are rusty so I can't comment about Suhosin but their forums do seem active, and it seems there are 'issues' with it.

I get concerned when the last 2 release dates of a product were 2007.03.06 and 2007.03.04 generally I find if a product has so many releases, there is something wrong there. It may just be a group of happy hackers adding new bits or that they have not tested/designed the new features properly and have introduced bugs

I hasten to add I am in no way criticising Suhosin, I know absoulutely nothing about it.

Bradml24-Mar-07 1:28

Re: Can someone test this on php 4.46 under Linux?

24-Mar-07 1:28

The reason for so many releases is that PHP is constantly updated and therefore compatibility issues are encountered. Also they update it to protect against the latest PHP vulnerabilities.
