Automatic iframe-to-iframe refresh??

VenomX

Greetings,

First posting here, but I'll get right to it. I want a page in an
iframe to refresh the page in another iframe, but not through a
regular href link. What I want to do is to have pageA.php in the
first iframe meta-refresh itself every 30 seconds or so (this is not
visible to the user) and check the database, and if it encounters
an event in the MySQL session handler that prompts it to refresh
pageB.php in the other iframe, it will do so without the user
having to click or do anything him/herself.

I've written the session handler myself and know how to check
for the event I want, but how do I actually make pageA.php in
iframe 1 refresh pageB.php in iframe 2 when a certain condition
is true? Is this possible? Can it be done with Javascript maybe?

Any help with this would be MUCH appreciated, as it's currently
frustrating the snot out of me.

JavaScript I suppose. Build a function that calls window.location="pagea.php", set a Timeout of 30000, call it in pagea.php body tag with "onLoad" ???

While this seems to be a better way of reloading the first page (thanks!) it doesn't seem like you can affect the second page in another iframe with window.location, or can you? The pseudo code for what I want to do is kinda like this:

Start with pageA.php in iframeA, and pageB.php in iframeB.

Every 30 secs, reload pageA.php and (within pageA.php){
check database for refresh-iframeB-value();
if(database says refresh-iframe😎{
refresh(pageB.php in iframe😎;
}
}

And the one thing I can't figure out is how to refresh pageB.php in iframeB from within pageA.php in iframeA. Can't see if/how it would even be possible, I DID figure out how to refresh the main page with top.location.href which reloads both iframes, but this is not very pretty and not quite what I want to do, so, any thoughts? :/

Heh, I think I was too quick to dismiss your answer, fiddled around a bit with it and discovered parent.iframeBname.location.reload(); worked great. Thanks! :o)

You're welcome. JavaScript is all about the browser, just as PHP is all about the server. One of the difficult things about JavaScript for me what that it is so OO, and also that it continually morphs with new browser versions, and that the syntax varies for which browser is being used. OTOH, it's handy when you need stuff like your refreshing, above. I was glad I could help, and am glad you found a solution. It's great to learn, eh?
