simple header function question

PHPslide

Can you make a header function go into a certain frame... or say go target="_blank" ?

So basically can the header function be controlled to where it goes similar to target="_parent" etc. with HTML?

ANY help is appreciated.

Thanks.

No; as you say, that's HTML. Headers are part of HTTP.

OK... just checkin...

Is it possible to do: (also, how would be the correct way since I don't think this would work.) I'm trying to reload the page without typing the URL in.


header("Location: $_SERVER['PHP_SELF']");

that would redirect the person to the same page, upon load of the page. you want to reload the page AFTER the user views the page.

look into the META command "REFRESH"

No offense please.... , but I ask a question because I need an answer to that question not a "You are asking the wrong question" response.

Now you probably know a better method then this for what I am doing but this is all I know right now as I am just still learning PHP slowly forever now.

	if(!$_POST['alias'])
    	{
        header("Location: [url]http://site.com/admin/index.php[/url]");
        exit;
    	}

I don't want to type that out everytime. So I'm asking if their is an easier way to just say, reload the page? I was thinking the $PHP_SELF function but that just isn't right to me either.

So... any help on this someone?

Please don't take offense at my initial response mattsinclair. I did not mean it in a hostile way at all. 🙂 😃

there's nothing to take offense to...

when you say reload, when do you want to reload it? there are a few different ways to reload a page, and all of them are for use in different situations... for example:

a META REFRESH tag would be used if you want to refresh the page in X amount of seconds... i.e. you're waiting for something to happen serverside, and you want the browser to keep checking over and over. it's basically like having the user click "refresh" every X amount of seconds.

header("Location: {url}"); would be used when you want the page to be IMMEDIATELY redirected to another place. Headers can only be sent out before any text is sent... so, if you did this, the user would see nothing, he would be immediately sent to whatever location is in the header. this would be for use when you want one page to decide where the user goes next...dynamically.

if you want the page to be refreshed when the user clicks on something you can either make an HTML link to the same page, "<a href="index.html">click here to refresh</a>" if the page is called index.html, or you can use javascript to refresh (can't remember how at the moment). Watch out when you use $PHP_SELF Becaues it's not always avaliable on every server you use.

it just depends on when you want the page to be refreshed, what's your situation?

Your missing the whole point. Do you know PHP? Look at the code I put down before your last post... just that right there.

I know about meta refresh etc... I been designing and building web sites for 3 years now intensely somewhat. Just recently got more into backend programming with php etc.

Anyway... yeah refer to the code before your last post. My question is "basically" what php code can I use in replace of a URL to the page the code is on?

Instead of typing header:Location http://www.bla.com

I'm trying to get out of typing the URL. it might nmot make much sense to you, but I have a program where this would be the easiest fix for a kinda inconvenient problem.

Yes, I know PHP. Now you have said something for me to take offensively. Maybe you are psychic, or maybe you know yourself, and you knew you were going to say something stupid.

If you knew how to ask a question in a logical manner, you would have asked that question initially.

Try

echo $SERVER["HTTP_HOST"].$SERVER["REQUEST_URI"];

For someone who has so much experience in web development... you should know how to use a manual.

What did I say offensively? My bad. If it was when I asked if you know PHP... I was not meaning it sarcatically. I was being serious.

I asked the question just fine the evry first time I asked it. 🙂 You just didn't see a reason to answer it.

Sorry. I didn't mean anything offensively.

mattsinclair

It's okay. No offense taken. Not to argume semantics, but technically you asked about a refresh not a relocation. I was under the impression you needed help in refreshing the current page, not redirecting to the current page. The quesiton could have been phrased in a more clear way, but it's okay... the problem was solved.

Be careful, if the conditions are right, you will get an infinite page loop and the user will always be sent to the same page over and over.

I really don't see any reason why you would want to relocate a page immediately upon loading, but if you must, make sure that you never allow it to loop for ever. Due to the danger of this happening, you might want to reconsider the method you use.
