redirecting to a page and using POST METHOD

[Tea_J]

A quick on guys:

1) What are the methods of redirecting someone to another page via PHP?

-i use header("location: blah blah)";
- occasionally, for time delays i print the "meta tag redirect function of HTML"

is there other ways i dont know about?

2) How do you rediredt to a page and SEND variables via post?

I used to use
header("Location: myscript.php?a=1234");
to pass in GET METHODS. But on my current thing, i need to pass it via POST.

Any advises you guys??

Thanks

Tea

for your second issue: did you consider using cookies yet?

[Tea_J]

well, i want to keep my scripts as simple and short as possible in order to avoid confusions and issues later on.. although using cookies is a way, i want to skip that part (and any similar tasks like that) if i can...

So, what im hunting for really is a way to directly send the variables from one script to another..

i'm pretty sure the only way you can pass POST data is with an auto-sending (onload) JS form with method="post".

[cosminb]

search this form for "POST simulation" or "simulate POST"

[Tea_J]

alrite. thanks you guys.

Why not just create a form w/ the variables you need to submit stored in hidden fields and use JavaScript to auto-submit the form?

i believe i already suggested that...

Well guys, i know lots of work arounds really for this... the problem is, they are "work arounds". I really wanted to know if there are "official" ways of doing this. Like the header() function having a post methid that i dont know about or something like that.

Thanks for the help though, but im not looking for a work around. 🙂

The java script is a good suggestion, I don't see how the ideas presented are work arounds, they are solutions to your problem. I auctully came here today to find a solution for your exact qustion and will be implementing the javascript solution.

You might search php.net for the curl function, as you can post to another site using it, however I believe it is more for scraping than redirectin? Kinda like the fopen function.

there is no way to do it from PHP. the client must initiate the POST request, and PHP cannot tell the client to do that.

work arounds are solutions mate. 🙂 But they are still work arounds.. i was particularly looking for a specific function or syntax.. 🙂

Thanks mate. Concluded.

thanks all!

look at Client URL Library Functions

[Moonglobe]

cURL can initiate the POST from PHP, but not from the user's browser, which is what he wants.

[Tea_J]

i see what you mean guys. CURL is addinng more complications/lines than just simply making a cookie.. sooo..hmm..

ok so skip that. for my 1st question, what are the methods of redirecting a user to another page from php?

I use header("location🙂 but, this wont work if i put my "anti - cache" headers

header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
header("Cache-Control: no-store, no-cache, must-revalidate");
header("Cache-Control: post-check=0, pre-check=0, false");
header("Pragma: no-cache");
header("Content-Type: text/html; charset=utf-8");

because, obviously, header's are already sent

[Moonglobe]

no it'll still work, becuase it's just another header. as long as you dont output anything.....

FWIW, I hate the term "work-around." It's overused. The only true work-around is a solution that has to be used to bypass or prevent bugs. An indirect solution, even though it isn't an orthodox PHP function, is still a viable solution, especially if it is the most straightforward.

Sorry if my term for "work around" doesnt match your definition..

As i have said before, what i meant was:

Exhibit A: Solution/Official Function/most practical method/whatever you wana call it

$data = file_get_contents("mydata.txt");
echo $data;

Exhibit B: workaround/longer method/whateever you wana call it.

$file = fopen('mydata.txt","r");
$data = fread($file,100000);
echo $data;

I know they're both GOOD SOLUTIONS, but what i MEANT was, if there was a FUNCTION that would make things easier.. so please dont limit your understanding to merely definitions. I'm not here to debate what is a solution and what is a work around.. i think i explained this clearly in my earlier posts.

Thanks for the criticsm though.

Umm.. mine shows an error that says "headers already sent"... 🙁 i know that's odd but it does show... nevertheless, i am still interested in knowing what other methods of redirection you guys use.

thanks

[Moonglobe]

well come to think of it if you're sending all those headers then you're probably echoing stuff.... if you're just redirecting you dont need to send all the other headers.

[Tea_J]

if you're just redirecting you dont need to send all the other headers.

Well, it's not like that.

My php file needs to be uncached - hence the headers on top of the script. The script evaluates some values and present it to the user.. if there is a missing variable, it REDIRECTS TO AN ERROR PAGE.. So, I'm not just redirecting.. I only redirect if i have to.- and usually, redirection happens sometime in the middle of the script and down
