PHP - Receiving Post Data Through Proxy (paypal Ipn Listener)
I'm trying to set up paypal payment processing on my website. I have godaddy shared hosting (<--mistake) and I'm trying my hardest to not switch hosts. The payments process fine, it is the listener that I'm having problems with. Paypal POSTs data to a script for which you set the url to a "listener" script in your settings. When a payment is made.... they POST the data to the listener script... you encode the data...append it all together plus another variable and send it back to be verified that it matches... Well I'm not too worried about the script working and all that... the problem is I'm not even RECEIVING the post. I have a simple foreach loop gather and append the data into a string. I have it set up right now to insert into MYSQL just so I can SEE if it's working....You can check your IPN history and I can see that payments are made but paypal is sending it over and over it's in a "retrying" state with a 408 error. My server is not sending a 200ok response.
After 4 days of bashing my head against the wall I figured out that there's a problem with godaddy shared hosting.. If I use a virtual private server with the SAME script from godaddy it works just fine. But on the shared hosting it blocks it for some reason...After calling paypal and godaddy countless times with them pointing their finger at each other... one godaddy support rep tells me that I should set my script up with a proxy and he gave me info which I will show you in the script... This is what I need help with right. How can I receive POST data through a proxy in my script.... I want to add that this doesn't make sense to me because in my script I also have the word "yes" insert into MYSQL even if the script is hit at all... All this time my script is NEVER even touched by paypal... So.. if I add this proxy stuff... how will let my script even be accessed? I'm not sure how servers work together too well to process things. It just didn't seem like the proxy thing would even help when my script can't even be accessed it seems. Any help is appreciated. Here's the simple code I'm working with: $con = mysql_connect("","","") or die(mysql_error()); $db = mysql_select_db("swellshirt",$con); $ip = "64.202.165.130"; // proxy IP <-- IP... $port = 3128; // proxy port $url_proxy = 'http://proxy.shr.secureserver.net'; // read the post from PayPal system and add 'cmd' $req = 'cmd=_notify-validate'; foreach ($_POST as $key => $value) { $value = urlencode(stripslashes($value)); $req .= "&$key=$value"; } mysql_query("INSERT INTO orders (description, street) VALUES ('$req', 'yes') ") or die(mysql_error()); Similar TutorialsI am trying to write a Paypal IPN Listener that will create a confirmation key in the order database I have on the server. Upon completing the order it will then send a email to the buyer with a link to a file upload page with the confirmation code embedding so that when the buyer goes to the upload page it can authenicate based on that code prior to allowing the person to upload a file. I has been a pain and is still not working. Similar to an email confirmation when some one signs up as a user on a site, but using the Paypal order information and the listener to generate the confirmation and authentication. IS THIS POSSIBLE? I am writing a listener to handle IPN notifications from paypal, and one thing I cant seemt o find anywhere - How does IPN handle pending payments, that are then completed/denied? For example, if paypal invokes my IPN once the payment is made, but pending, with a particular transaction ID, when the payment completes, does it then invoke my IPN again, with the payment status as 'completed'? If so, will this second IPN have the same transaction ID? It would seem logical that the same transaction ID is sent again, as it is actually the same customer transaction, however reading this on thepaypal website suggests otherwise: "Avoid duplicate IPN messages. Check that you have not already processed the transaction identified by the transaction ID returned in the IPN message. You may need to store transaction IDs returned by IPN messages in a file or database so that you can check for duplicates. If the transaction ID sent by PayPal is a duplicate, you should not process it again. " Help would be appreciated!! i have a shopping cart set up with mysql with a $_COOKIE['cart_id'] used to call all rows with cart_id... i have a while loop print out all the items in the cart $sql2 = mysql_query("SELECT * FROM cart WHERE cart_id = '$cart_id'") or die(mysql_error()); while($row = mysql_fetch_array($sql2)){ then i have it echo out the name...desc... quantity of each item... but the quantity is set up to be able to change and i have a form set up and i'd like to have each item be able to be changed at once if they wanted....but being multiple rows... there could be multiple $_POST['quantity']... echo "<td><input type='text' name='quantity' value='".$quantity."'/></td>"; there is a unique id for each row in the table that i'd like to set up with an array to post... i'd like to set up an array $array[$uniq_id] => $quantity; and somehow POST this array name='$array[]' and then on the action end... be able to call it by having foreach($quantity as $uniq_id => $qty){ mysql_query("UPDATE cart SET quantity='$qty' WHERE id='$uniq_id' "); } i'm not sure if i'm approaching this the right way... the array part is leaving me stuck...any help is appreciated..thank you! I have some data I'm posting from Swift to my php file via x-www-form-urlencoded. How can I decode this POST data? Hi all, I should first mention I'm not much of a coder, I'm using PHP to create a custom weather solution for myself. Basically am pulling XML from weather.gov and working with the data. So far, so good. I'm getting the data I want displayed correctly, but noticed when I refresh the page I sometimes receive old data. (From the past hour, two hours, etc.) I figured this was cached info and I'm trying to figure out how to clear that out. This is how I'm accessing the XML: $url = 'http://forecast.weather.gov/MapClick.php?lat=40.65160&lon=-74.34420&FcstType=digitalDWML'; $xml = file_get_contents($url); I did some research and tried the following headers, but that doesnt seem to work: <?php header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); header("Cache-Control: no-cache"); header("Pragma: no-cache"); ?> Also tried appending a random number onto the $url, (as per a forum question/response somewhere) but that didn't work. Anyone suggestions would be great. Thanks Apologies, first off: I only venture into PHP occasionally and my problem is something very very obvious... The data I'm getting back from the script below differs radically from the data recovered by the same SQL applied directly in phpMyAdmin. $sql = mysql_query('SELECT `fid` , `title` , `extension` FROM files WHERE `mid_FK` = 2353 ORDER BY `title`') or die ("Sorry: cannot retrieve files."); $files_found = mysql_fetch_array($sql); $num_files_found = count($files_found); The native SQL returns three rows from the table, all with entries in each column. What my script produces as relevant variables is this. Code: [Select] [sql] => Resource id #6 [files_found] => Array ( [0] => 961 [fid] => 961 [1] => Abstract of Case [title] => Abstract of Case [2] => doc [extension] => doc ) [num_files_found] => 6 This is the first row of the SQL results, duplicated. Whereas what I need are the entries for all three rows. I'm baffled, not least because I copied it out of another script I wrote last time I was doing this sort of thing, which has been working fine ever since. This has probably been asked a bunch of times , but : I only recently started to self learn PHP , and this small project i am making is quite a challange for me. The scripts below are not realy writen by me , but i wished to tie them together to get a fully working code. What is suppose to happen is : In the form i wish to put a special button that puts extra input fields in the form. After the form is submited ,with whatever amount of feilds in it, the data goes to a processing.php file that sorts all the info gathered and finaly sends all this data formated in to the last file that will be inluded in the index.php. i already have the code for increcing the amount of inputs but the problem is , all inputs have the same names. Coz of that i get a mess. What i need is each input to have a unique name or id , that way the processing file would receive different names(id's) with different values(what ever is writen in the inputs by users). for example: I have 2 enitial fields displayed on form.html , i click the button "add new" 5 times and add 5 more input fields. All this data must be sent to a process.php and on the output write all of this information formated in the last file in a row that will be displayed in the index by useing <?include("blablabla.php");?> The input increment is done by a java script. the problem is sending data with unique id(name) and receiving it. The form file : <?include("header.php");?> <?$i = 1; ?> <script type="text/javascript"> function validate(frm) { var ele = frm.elements['feedurl[]']; if (! ele.length) { alert(ele.value); } for(var i=0; i<ele.length; i++) { alert(ele[i].value); } return true; } function add_feed() { var div1 = document.createElement('div'); // Get template data div1.innerHTML = document.getElementById('newlinktpl').innerHTML; // append to our form, so that template data //become part of form document.getElementById('newlink').appendChild(div1); } var ct = 1; function new_link() { ct++; var div1 = document.createElement('div'); div1.id = ct; // link to delete extended form elements var delLink = '<div style="text-align:right;margin-right:65px"><a href="javascript:delIt('+ ct +')">Del</a></div>'; div1.innerHTML = document.getElementById('newlinktpl').innerHTML + delLink; document.getElementById('newlink').appendChild(div1); } // function to delete the newly added set of elements function delIt(eleId) { d = document; var ele = d.getElementById(eleId); var parentEle = d.getElementById('newlink'); parentEle.removeChild(ele); } </script> <TABLE> <style> #newlink {width:600px} </style> <form action='sendorder.php' method='post'> <div id="newlink"> <div> <table align="center" border=0> <TR><TD><B>Product:</B> </TD><TD><input type=text name=prodname1 value="<?=$_GET['prodname1'];?>"> </TD> <TD><B>Price:</B> </TD><TD><input type=text name=price1 value="<?=$_GET['price1'].$curency;?>"><b>%</b></TD></TR> </table> </div> </div> <p> <br> <input type="submit" name="submit1"> <input type="reset" name="reset1"> </p> <p id="addnew"></p> <FORM> <INPUT type="button" value="Add New" name="button2" onClick="javascript:new_link()"> </FORM> </form> <!-- Template --> <div id="newlinktpl" style="display:none"> <div> <table border=0> <TR><TD><B>Product:</B> </TD><TD><input type=text name=<?$_POST[++$i];?> value="<?$_GET[$i];?>"> </TD> <TD><B>Price:</B> </TD><TD><input type=text name=<?$_POST [++$i];?> value="<?$_GET[$i].$curency;?>"> </TD></TR> </form> </TABLE> <?include("footer.php");?> in the code above i tryed to make the programm POST the numbers in the name increcing it by 1. But when i click submit i get offset error. The processing file : <? $timestamp = strftime("%d-%m-%Y %H:%M:%S %Y"); // for later use (ignore it) $i =1; #################################################################################### if(($_POST['prodname']!="")&&($_POST['price']!="")){ ############################################################ $writetocsv = $_POST['prodname1'] . "," . $_POST['price1']"%" <BR> . $_POST[$i] . $_POST[$i]; $fp = fopen("data/data.csv", "a"); fwrite ($fp,$writetocsv); fclose ($fp); echo "<script>alert('Data sent.')</script>"; } else{ echo "<script>alert('Error! Please fill the form!')</script>"; } echo "<script>location.replace('index.php')</script>"; ?> Perhaps someone knows a easyer way , since i am not sure how to make stuff due to the lack of knowlage in php. I also tryed arrays but , as said before , too tough when you are a noob Please help. I am being sent an XML feed which needs to be downloaded in a 'compressed way'.

TIA! WR! Hi all, This is driving me insane! Basically I am simply trying to setup a reoccurring payment, in live and sandbox I get an error once I submit login details Code: [Select] The link you have used to enter the PayPal system is invalid. Please review the link and try again. The code I am sending to paypal is: header("location: https://www.sandbox.paypal.com/cgi-bin/webscr? cmd=_xclick-subscriptions& business=sandbox@minecraftclan.com& item_name=Item1& a3=3.00& p3=30& t3=D"); My sandbox account is 'sandbox@minecraftclan.com', I really cant see what the issue is! It will show the payment screen, but error occours after logging in with sandbox details, the same if I run to the live site and use an real paypal account Any ideas? EDIT: This iswhat a view source on the error page looks like: s.prop1="xpt/Merchant/hostedpayments/Error"; s.prop6="6FW885512W222534S"; s.prop7="Personal"; s.prop8="Verified"; s.prop9="Unrestricted"; s.prop10="US"; s.prop14="The link you have used to enter the PayPal system is invalid. Please review the link and try again."; s.prop16=""; s.prop34="PayPalCredit:Servicing:CO:NoTransactions"; s.prop15=""; s.pageName="xpt/Merchant/hostedpayments/Error::_flow"; s.prop50="en_US"; s.prop18=""; That mean anything to anyone?! Here is something i dreamt up, i know there is a way for this to work, but i'm not having any great ideas at this point. I want to be able to auto increment through the $_POST[] array data sent from a PayPal IPN. Sample return data looks like item_number1=val item_name1=val so on and so forth. The idea is: While there are $_POST item_numbers, do something with it. The loop continues until there are no more item_numbers. I don't want to use the static methods eg: explicitly defining item_number1, item_number2, ect. This is what i thought would work, but keeps failing -> the script doesn't enter the first condition: $x = 1; // set the initial item number while(isset($_POST['item_number$x'])){ $qty = $_POST['quantity$x']; while($qty > 0){ // step through each item response result, setting each item to paid $package_id = $_POST['item_number$x']; update_paid_status($transaction_id, $package_id); $qty--; } $x++; } Any Ideas? Hi I have a little strange problem. I cannot get the post data from my form. It works fine if there is 10 or 15 user but reaching 40 or more than form values not posting. This is output of size: echo (int) $_SERVER['CONTENT_LENGTH']; ===== 22164 Code: [Select] if(isset($_POST['hiddenField'])) { // do some work; } $sql = mysql_query("SELECT id, name FROM user WHERE shop_id = '" .$_SESSION['id']. "' ORDER BY name ASC"); while($row = mysql_fetch_array($sql)) { echo ' <div style="width:100%; border:solid 1px #CCC; background-color:#f1e7e7; margin-bottom:5px;"> <table class="tableSmall"> <tr><th width="81">' .$row['name'].

"' AND date = '" .$days_no_kanji[$j]. "'"); $row2 = mysql_fetch_array($sql2); if(mysql_num_rows($sql2) == 0) { $start = "00:00"; $end = "00:00"; $m = 0; } else { $start = $row2['user_start']; $end = $row2['user_end']; $m = 1; } echo ' <th><input type="hidden" name="userData[]" value="' .$row['id'].

Hi guys, I think I may be losing my marbles over this form I've put together. I'm trying to get my code to post the following to a database but my MySQL and PHP isn't that good, so wondering if any one could possibly suggest what I could do? Here is my code: Code: [Select] <?php // we check if everything is filled in if(empty($_POST['fname']) || empty($_POST['lname']) || empty($_POST['email'])) { die(msg(0,"All the fields are required")); } // is the sex selected? if(!(int)$_POST['sex-select']) { die(msg(0,"You have to select your sex")); } // is the birthday selected? if(!(int)$_POST['day'] || !(int)$_POST['month'] || !(int)$_POST['year']) { die(msg(0,"You have to fill in your birthday")); } // is the email valid? if(!(preg_match("/^[\.A-z0-9_\-\+]+[@][A-z0-9_\-]+([.][A-z0-9_\-]+)+[A-z]{1,4}$/", $_POST['email']))) die(msg(0,"You haven't provided a valid email")); // I think here is where I need to put something to get the data into a table! echo msg(1,"registered.html"); function msg($status,$txt) { return '{"status":'.$status.',"txt":"'.$txt.'"}'; } ?> How do I get the $_POST['day'] and $_POST['month'], $_POST['year'] etc into a table? It should be so easy but my head is hurting from trying lots of things and tutorials online. Any thoughts my PHP Freaks? im trying to understand this Post Data script it's not posting, no errors: postdata.php Code: [Select] <?php //create array of data to be posted //$post_data['firstName'] = 'Name'; $post_data['item_name'] = '12345'; //traverse array and prepare data for posting (key1=value1) foreach ( $post_data as $key => $value) { $post_items[] = $key .

When i submit and post the form, can i use these values as part of the submission and put their data-value into the db? Thanks as always in advance. I'm doing an ajax call from javascript using jquery library: Code: [Select] ajaxCall: function(process, obj, type){ $.post("registration-post.php", type + "=" + process, function(data){ if(data==""){ $(obj).css(registration.errorNotificationType, registration.validatedColour); }else{ $('.error').append($.trim(data) + "<br />"); $(obj).css(registration.errorNotificationType, registration.errorColour); registration.progress = false; } } ); } When the ajax calls the php page, I want the php page to know what post information the javascript has sent, rather than pre-defining what the PHP should be trying to retrive from the POST data. Something like // pseudo $_POST["whateverwassentfromajax"] I want to do this because I want to have one function doing everything. So in my javascript I am saying, check if the username and email have already been used... But i dont want to call two different php functions. //pseudo function 1(){ $_POST["username"]; } function 2(){ $_POST["email"]; } Is there a special way to know which post data has been sent. Or do i need to do a few if statements in php. Hello
I have a nusoap web service running, which is fine, but I need to send a new variable in the parameters which decides what database to use...
This is how I call the function:
$params = array( 'region' => '1' ); $response1 = $client->call('function1', array ($params)); // response will be in JSON |
