Hi guys/girls,

I have to apologize if this issue has been discussed in detail before but I
couldn't find anything obvious so far.

What I need/want to do is to :

1. Take POST data from a form (no problem)
2. Do whatever i need to on the target page (no problem)
3. Pass some other data on to a 3rd page as a POST
request.
4. Get the browser to follow to said 3rd page.

All this is happening via SSL.

So basically what i am trying to do is to "fake" whatever happens
at a normal POST request that is handled by the browser.

Now point 4. in my example above is giving me a massive headache,
I have managed to pass data on to the 3rd page as POST quite comfortably
using cURL but the browser doesn't follow (ie. the URL in the address bar
remains unchanged).

I did see that there is a FOLLOWLOCATION option you can set in cURL when you
do you request, and though "wicked, just what I needed" only to find out
that it's not working (probably because I understand what it does wrong).

Pretty pretty please if anyone knows a solution for the above, let me know.

Oh, and I'd also like to add that the information I am trying to get to the
3rd page in the example is sensitive (Credit Card details etc.), so $_GET
and $_COOKIE are out of the question.

ANY help would be appreciated.

Kind regards,
Ben

If the information is sensitive, why are you trying to fake a POST
submission? A POST can be received from anywhere. SSL is just
encrypting it, not verifying the client is the same. I would use
session variables to store information you need to access from page
to page. That way you can verify that you are talking to the same
computer from the first two pages.

Hi,

it seems you have no understanding how http protocol works.. I can't
learn you the whole thing, but I can give you some hints. Read something
about HTTP
(http://www.digital-web.com/articles/powering_the_web_with_http/),
install some network sniffer (ethereal, HttpWatch for IE - great tool
for beginners) and see what happens.

- you cannot force browser to POST something somewhere with PHP. You
have to realize, that PHP is running on server, but the browser is the
client.
- you cannot use curl to do it. With curl it all happens on the server.
If you want to use curl, you have to use same technique used by "web
based anonymous proxy". Return all loaded data to client, rewrite urls
to your script, handle everything correctly until client closes browser.
Very complex stuff
- followlocation has nothing to do with browser. it only says to curl to
evaluate Location header and do auto-redirection
- sensitive information? GET, POST, COOKIE, everything could be intercepted
- your only help is javascript. You can generate something like this to
client browser with php. But you couldn't hide sensitive information
this way.
<body onload="document.forms.myform.submit()">
<form name="myform" method="post">
<input type="hidden" name="..." value="...">
</form>
- think about your problem and possible solutions again

What the other people said about HTTP. It's time to look at this from
another angle. Why do you need to process this data twice? What are you
trying to do?

Are you, perhaps, trying to make an online payment where you store the data
locally (page 2), then perform some kind of credit check (page 3)?

If so, would something like the following work?

Page 1 -> form post to page 2
Page 2: process form inputs, write to DB or whatever, communicate with page
3 as necessary (possibly using curl) and finally send a redirection header
to the browser sending it to a success/failure page based on what page 3
told you

The only way to do it would be to write your own client uploading
application in the likes of Java or ActiveX.

Anything client side is always going to fail because it doesn't know
about the size of the file until it has it, by which point it's too
late.

I know that part of the POST transaction with the client and web server involves sending the 'content-length'.. there's no way to tap into that before the file's uploaded though I guess.
(example of how to manually POST using Python at leastfound here: http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/146306)

Failing that.. I think someone had mentioned Java, but here's a quick and dirty way to do it in Javascript (found on: https://lists.latech.edu/pipermail/javascript/2003-April/005190.html)

var myFile = new File("c:\temp\myfile.txt");
myFile.open("r");
alert('myFile length: ' + myFile.getLength());

Havn't tested it, but I'd rather use a tiny Javascript than a Java applet.

My apologies if I missed something in the thread, I kind of speed read through it and wasn't going to respond, but it was nagging at the back of my brain so I had to do a quick search or two.. hah

Hi,

I have been trying _several_ ways to control the size of the files that
can be uploaded in a form.

The problem is that I was able to detect file size after complete file
is transfered.

I need to detect file size before all file is transfered, in order to
cancel it and preserve server resources.

Any ideas?

Thanks in advance
Ruben Rubio Rey

Somehow I don't think any browser is going to give JS access to
arbitrary files on the user's system like that.

Yeah, you're right. I didn't test that before I posted it.

Looks like you can do it as long as your clients are running Windows and you can use Active X or another Windows trick using something like JScript, but with pure Javascript it looks bleak.

I tried to use something like this:
img = New Image();
img.src = "somefile.ext"; // NOT an image file
alert(img.fileSize);

But found out that this is an IE-only trick as well. Nobody else seems to support the filesize property on image objects. Funny thing is, even in IE it didn't work. Even when I actually used an image for the file name.

Oh well.. guess that Java applet might be the best way then, to keep it cross platform and all that.

Check to make sure absolutely nothing before the header() function is outputing anything. No echos, no prints, no var_dumps, no HTML or even blank lines.

If it's something tangible like an echo or print or something, then putting an exit()/die() function right before the header() function then looking at the HTML source that you get should show you what the offending output is.

But again, if I recall, it can be something as simple as an empty line.

-----------------------------------------
<?php

// This should work because there's no output or white space above header()
header('Location: thanks.php');

?>
-----------------------------------------

-----------------------------------------

<?php

// This should fail (if I recall) because of the blank line that's sent
// before the PHP code block. This is considered output, and can't come before

header('Location: thanks.php');

You don't have to put anything specific, it just stops the script from executing.

You can optionally put text in there. I like using die() for some reason (shorter? more.. err.. aggressive? hah) so I'll using commands like:

die("Made it to this point...");

I might use this to see if I got to a certain conditional or not..

Anyway, if you're getting that error, then there's definitely something being sent before the header() is executed.

Check any require() or include() files, check all the code above your header() statement. So far I've never seen or heard of any bugs with header() where it'd mysteriously bomb out in this manner, it's always been something output and it's always been something people kick themselves for not seeing before. hah

Keep looking, you'll find it.

I checked and no white space involved. What would I need to put tin the
exit()/die() function?

when I put the die statment in and test the form I get, the html prior to
the form and what I put in my die statement eg:"made it to this point". The
form submits and I get the info, but I am not redirected to the Thanks page.

My question is how do I determine from this what is causing my error?

I'm trying to setcookie('username',$username,15552000) but on
subsequent pages $_COOKIE('username') is always null.

I verified that I'm setting it before any other output is sent to the
browser. I verified that $username does have some valid contents. I
also verified that the browsers I'm testing are set to allow all
cookies. I do have a $username and a $_SESSION['username'] that
contain the same data.

I'm all out of ideas for where to look further to debug this - any
suggestions?

Well, the stupid/obvious question is: are you checking $_COOKIE
('username') like you posted or $_COOKIE['username'], which is
syntactically correct?

Secondarily, have you set your browser to prompt you when a cookie is
sent and, if so, what happens?

Is that just a typo? It should be $_COOKIE['username']

Oops, yes, that was my typo in the email - it is correctly $_COOKIE
['username'] in the code. Thanks.

attached mail follows:

Unless I'm mistaken, you appear to be setting the Expiration date of the
cookie to "Mon, 29 Jun 1970 17:00:00 -0700".

Which would cause the cookie to be unset, if it were already set, and do
nothing otherwise.

Good catch, Chris. I was wondering about that myself but hadn't taken the time to see if setcookie() used regular serial time or if cookies had another time standard.

echo date("m/d/Y h:i:s", 15552000);

06/29/1970 08:00:00

That's what I get.

D'Oh! You guys are absolutely right. I was trying to go for 6 months,
which works now if I say time()+15552000 instead of 15552000. And the
documentation shows that exactly - apparently I read right over it,
even though I studied it minutely before posting.

Oh well...my wife would have the same complaint about me when I can't
find the can opener when it's sitting in plain view.

Some Ideas:

Internet Explorer, and those that mimic its broken behaviour, require
BOTH a time AND a directory (use '/') if you are going to provide a
time.

Is 15552000 sufficiently in the future to be valid? Use time() +
(60*60*24) to be SURE.

Or avoid both these issues, and leave out the time argument for now,
making it a "session" cookie, only valid as long as the browser stays
open.

DEFINITELY configure your browser to let you confirm cookies before
accepting them, so you'll know what the cookie is getting sent.

Windows XP with Service Pack 2 has made a nightmare out of cookies, by
default no longer accepting them -- And I THINK this changes based on
your adding that new goofy compact privacy policy header Microsoft
made up.

It's gotten to the point where I just don't care if IE works or not
for the parts of some of my sites that require member login from
people who need access, and I don't really care if I lose visitors or
not in that particular area. I just tell the users to switch
browsers, or live without the access they want. Works so far -- they
just switch to a better browser.

You don't mention which distro you're using, but Fedora Core 4 has a
php-xml rpm to "...add support to PHP for manipulating XML documents
using the DOM tree, and performing XSL transformations on XML
documents."

Hope this helps,

I'm using the PEAR Soap package and having problem accessing another sites's webservices. When i
do something like this:

<?PHP

$wsdl_url = 'some_wsdl.xml';
$WSDL = new SOAP_WSDL($wsdl_url);
$client = $WSDL->getProxy();

$web_service_result = $client -> some_web_service($param1,$param2,$param3,$param4);

$web_service_result returns the soap_fault Object. The message portion contains the line
"curl_exec error 6 Couldn't resolve host 'secure.example.com' " Also if i try to grab the WSDL
file from the remote server the script doesn't seem to grab the WSDL ( i get a bunch of "Passed
variable is not an array or object" errors ). I think the problem is curl can't resolve the
hostname.

Also if i run
<?PHP
echo gethostbyname('http://bugs.php.net');
?>

It echos "http://bugs.php.net", no good.

When i try something like
<?PHP
$url = 'https://secure.example.com/index.html';
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER,TRUE);
$result = curl_exec($ch);

$cur_error = curl_error($ch);
curl_close($ch);

echo $result;
echo "<BR> Error: ".$cur_error;
?>

It doesn't echo out anything, however if run "curl https://secure.example.com/index.html" from the
command line i get back the page found at that address.

I'm running PHP Version 4.3.4 with CURL support enabled (CURL Information: libcurl 7.9.8 (OpenSSL
0.9.7c) (ipv6 enabled) ) on Red Had.

If i ping 'secure.example.com' the address resolves properly.

Any tips on things to try? Should i reinstall curl? SSL? Anything else i should investigate?

-k.

str_replace() is the first thing that comes to mind. From the manual:

// Provides: <body text='black'>
$bodytag = str_replace("%body%", "black", "<body text='%body%'>");

Using %keyword% and is kind of a template style method, but has worked out well for me (and I assume others) so try something along those lines.

You can also use arrays with str_replace to indicate a list of things that need replacing:

$template = "Please forward this to %NAME% at %ADDRESS%. Call them at %PHONE% if there's a problem";
$tags = array("%NAME%", "%ADDRESS%", "%PHONE%");

$userinfoQY = "select Name, Address, Phone from users";
$userinfoRS = mysql_query($userinfoQY);
while($userinfoRW = mysql_fetch_assoc($userinfoRS)){
$userinfo = array($userinfoRW['Name'], $userinfoRW['Address'], $userinfoRW['Phone']);

echo str_replace($tags, $userinfo, $templte);
}

Is that the answer you were looking for?

Is there a search & replace PHP command?

An example I am needing this for would be:

My name is replace_with_real_name

I want to retrieve replace_with_real_name from a mySQL database and put in
the name ... the key is that I want to put the person's name in various
position ... so I want to search for something like "replace_with_real_name"
and be able to put it anywhere in the sentence.
