I have a file called "receive_data.php" on my server, that receives POST data from excel vba constantly throughout the day. This file inserts data into the database as a log of which tools and reports are being used throughout the day for the business I work for.
I have now created a report that is generated onscreen when php file "show_data.php" is viewed.
When show_data.php is viewed, ideally I would like to 'ping' "receive_data.php" with similar values as below:
$_POST['code'] = 1;
$_POST['r_id'] = 24;
The company I work for uses very old browsers, therefore using something like AngularJS is not an option as it can be unreliable in anything older than IE9.
I could include "receive_data.php" within the php file, but it's still a case of being able to have the variables sent in as 'post' variables.
I could modify the "receive_data.php" file to accept variables, however...
Ultimately I do not want to modify "receive_data.php" in any way, if at all possible.
If this is possible, then great! If not, then I will have to look at modifying the file, but due to the business intensive needs, editing it is worse for us.
You can try something like this:
if( $curl = curl_init() ) {
curl_setopt($curl, CURLOPT_URL, '<path_to_your_script>/receive_data.php');
curl_setopt($curl, CURLOPT_RETURNTRANSFER,true);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, "code=1&r_id=14");
$out = curl_exec($curl);
echo $out;
curl_close($curl);
}

I have a HTML/PHP/JS page that I use for an automation process.
On load, it performs a curl request like :
function get_data($url) {
$curl = curl_init();
$timeout = 5;
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, $timeout);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($curl);
curl_close($curl);
return $data;
}
$html = get_data($url);
Then it uses DOMDocument to retrieve a specific element on the remote page. My PHP code handles it, makes some operations, then stores it in a variable.
My purpose as you can guess is to simulate a "normal" connexion. To do so, I used the Tamper tool to see what requests are performed, when I was physically interacting with the remote page. HTTP headers are made of UA, cookies (among them, a session cookie), and so on. The only POST variable I have to send back is my PHP variable (you know, the one wich was calculated and stored in a PHP var). I also tested the process with Chrome, which allows me to copy/paste requests as curl.
My question is simple : is there a way to handle HTTP requests / cookies in a simple way ? Or do I have to retrieve them, parse them, store them and send them back "one by one" ?
Indeed, a request and a response are slightly different, but in this case they share many things in common. So I wonder if there is a way to explore the remote page as a browser would do, and interact with it, using for instance an extra PHP library.
Or maybe I'm doing it the wrong way and I should use other languages (PERL...) ?
The code shown above does not handle requests and cookies, I've tried but it was a bit too tricky to handle, hence I ask this question here :) I'm not lazy, but I wonder if there is a more simple way to achieve my goal.
Thanks for your advices, sorry for the english
So essentially I am trying to simulate a form post using php curl. I use something similar to below...
curl_setopt($ch, CURLOPT_URL, 'http://example.com/update/93827');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, 'Subject=test&Content=test');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$content = curl_exec($ch);
Now that's all fine however, the website I am using requires that every field be complete and by what I saw when I was doing it manually and looking on firebug... It looks a tad unreasonable to get all that data (As you can tell from above, I only need to do 2 fields, however the website requires about 17 different fields that aren't required if you do it manually).
I have always gotten away doing it with the above method, but I thought it might just be easier if there was a way to input your data into the fields and actually simulating a post click so the website does what it requires to do.
If you are confused by what I mean I can elaborate more.

This is 1 way to do it. It forces a 'refresh' to the url specified after 0 seconds (immediately)
This WILL NOT work if you want to post values to a page, but I note you are using a query string in the url anyway.
echo '<meta http-equiv="refresh" content="0; ,URL=http://http://example.com/update/93827?Subject=test&Content=test">';
I am building a PHP script that needs to use content loaded from an external webpage, but I don't know how to send/receive data.
The external webpage is http://packer.50x.eu/ .
Basically, I want to send a script (which is manually done in the first form) and receive the output (from the second form).
I want to learn how to do it because it can surely be an useful thing in the future, but I have no clue where to start.
Can anyone help me? Thanks.
You can use curl to receive data from external page. Look this example:
$url = "http://packer.50x.eu/";
$ch = curl_init($url);
// curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // you can use some options for this request
// curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5); // or not to use them
// you can set many others options. read about them in manual
$data = curl_exec($ch);
curl_close($ch);
var_dump($data); // < -- here is received page data
curl_setopt manual
Hope, this will help you.
You may want to look at file_get_contents($url) as it is very simple to use, simpler than CURL (more limited though), so your code could look like:
$url = "http://packer.50x.eu/";
$url_content=file_get_contents($url);
echo $url_content;
Look at the documentation as you could use offset and other tricks.
I have just started a project that involves me sending data using POST in HTML forms to a another companies server. This returns XML. I need to process this XML to display certain information on a web page.
I am using PHP and have no idea where to start with how to access the XML. Once I knwo how to get at it I know how to access it using XPath.
Any tips of how to get started or links to sites with information on this would be very useful.
You should check out the DOMDocument() class, it comes as part of the standard PHP installation on most systems.
http://us3.php.net/manual/en/class.domdocument.php
ohhh, I see. You should set up a PHP script that the user form posts to. If you want to process the XML response you should then pass those fields on to the remote server using cURL.
http://us.php.net/manual/en/book.curl.php
A simple example would be something like:
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://the_remote_server");
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, $_POST);
$YourXMLResponse = curl_exec($ch);
?>
I have a form allowing a user to signup for a news letter which submits back to the page it's sat in for validation and adding the content to the db, however I also need to send an xml file to a third part using the information collected from the form to add to a mailing list. The data sent to the third party seems to need to be sent using the post method.
How can I achieve this?
I tried AJAX, but realised after a bit that AJAX isn't able to send info to external links so abandoned that.
Essentially the site needs to reload the page, validate the info sent to it, either return errors or add info the db and fire off the xml in the background, so having it send a separate form after reload isn't ideal either. Also the third party page when sent the xml through the main form loads it's own page, which is far from pretty and takes the user away from our site, not good at all.
You will have to validate in PHP and then send the XML from the
<?php
$hCurl = curl_init();
curl_setopt($hCurl, CURLOPT_PUT, true);
curl_setopt($hCurl, CURLOPT_HEADER, true);
curl_setopt($hCurl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($hCurl, CURLOPT_CONNECTTIMEOUT, 60);
curl_setopt($hCurl, CURLOPT_URL, $URL_TO_UPLOAD);
curl_setopt($hCurl, CURLOPT_HTTPHEADER, $aCurlHeaders);
// TODO it could be possible that fopen() would return an invalid handle or not work altogether. Should handle that
$fp = fopen ($XML_FILE, "r");
curl_setopt($hCurl, CURLOPT_INFILE, $fp);
curl_setopt($hCurl, CURLOPT_INFILESIZE, $finfo['size']);
$sResp = curl_exec($hCurl);
?>
Just replace $URL_TO_UPLOAD with your server that you want to POST to and $XML_FILE with the file you want to send and we are done!
I would recommend getting your server to submit the data to the third party once it has added the information to the database. It can even queue up this process and deal with it at a later date if needed.
There are lots of ways of doing this in PHP, such as Curl.
How about the XML is sent not by your user's browser, but generated and sent by your server? You could still use AJAX, and you'd have no headaches about users leaving your site.
Something along the lines of
Browser -> Server
Server -> write into own DB
Server -> generate an XML file and send it to the foreign server
