PHP - Calling Paypal Button Mamager Method

HI guys,,

I have created an online booking form with Paypal Buynow button.

After Clicking BuyNOW I want the customers to enter their Shipping details when they are on Paypal.

Phone and Address

How can i do that?

and also using on1 and os1 i can enter custom information. but it includes one value for example

Select Product Size: The Value will be Small or Large

What if want to have multiple values? like

Choose Colors: Red, blue, green, white go on.

User can choose one of those colors or multiple..

Please tell me how to do it.
Thanks

Waiting for your responses!

I need some help with showing a Paypal buy button or not if it's sold. Currently if the item is sold I mark it as sold but the button is still there. What I need I believe is an if statement to look at the sold variable to see if it's sold and then not show the Paypal Buy it button for that item only.
Any help would be greatly appreciated. Below is some of the code I use.

Hi

Can you call Class A's methods or properties from Class B's methods?

Thanks.

Ok. I know you can pass the object of a class as an argument. Example:


class A {
    function test() {
        echo "This is TEST from class A";
    }
}


class B {
    function __construct( $obj ) {
        $this->a = $obj;
    }

    function test() {
       $this->a->test();
    }

}


Then you could do:

$a = new A();
$b = new B($a);


Ok so that's one way i know of.

I also thought that you could make a method static, and do this: (assuming class A's test is 'static')

class B {
    function test() {
       A::test(); 
   }
}


But that is not working.


I'd like to know all possible ways of accomplishing this. Any hints are appreciated. thanks

Hi all,
I have a regular comment section and i want the submit button to call a mysql_query function in comment.class.php
so
Code: [Select]
<form method="post" action="../php/comment.class.php?action=addcomment" name="commentform" id="commentform" onsubmit="validateForm()">
<label for "body">Your Comment</label>
<div><textarea cols="20" rows="4" name="body" id="body"></textarea></div>
<input type="submit" id="submit" value="Submit"/>

and my comment.class.php is...
Code: [Select]
function addcomment($body){
$body=mysql_real_escape_string($_POST['body']);
if($body!=''){
         mysql_query("INSERT INTO comment(uid,screenname,body) VALUES ('$_SESSION[uid]','$_SESSION[screenname]','$body')") or die('lame');
}
header("location:../index.php");
}

but when I click submit, i'm taken to a blank page with the URL: http://test/php/comment.class.php?action=addcomment

any tips? and is there a better alternative to header?

Thanks

Hello

I am working in moodle and its code base is in PHP. I am a novice to moodle as well as PHP and not quite familiar with PHP syntax.

Right now I have built a Web page in moodle, and its view.php file I need to implement a fuctionality on click of a button.

On click of submit button, I am trying to implement a functionality and I have written the code for that under if(isset($_POST['submit]))
{ ...my code...}

Also while creating the form I have set the attributes as follows:
echo "<form method='post' action='" . $_SERVER['PHP_SELF']."?inpopup=". $_GET['inpopup']."&amp;id=" . $_GET['id'] . "'>";

But irrespective of whether or not I click the button, whenevr the page loads for the first time, it perform the code written in IF loop as well.

So Am i going wrong in implementing a functionality on click of button in PHP or is it something related to moodle, if anyone knows?
Any help or suggestions would be appreciated. As I am stuck with this logic since last three days.

Regards

Hi guys, my code below works with sanbox for paypal IPN but since it has gone live it doesnt do anything, so i made emails to send me where the issue is and it keep sending me $req = 'cmd=_notify-validate';

could you please tell me what im doing wrong here? my db connection should be fine as it does update the users on sanbox.

the account im paying with in paypal keep saying payment status unclaimed. it means the reciever has not recieved the money. I checked the paypal account where i recieve the moeny and looked into my ipn history, nothing there.

the same ipn address is used for my account when i tested it on sanbox,

 thanks

Hey guys i have created a paypal IPN script and it takes various info from users via paypal. Anyways i store their info into a database along with their email however i dont want them to be able to purchase again with the same email (long story) anways by the time i receive the info from paypal the payments already gone through so its too late for me to do the checking against the database. Is there anyway i can auto refund the payment do paypal allow this? Hope someone can help.

Thanks!

Hey All, 

I have setup a Paypal API to handle the recurring payments on my website, once the payment is completed I get a token id and ba_token id return. 

I am storing this in a database, but wondered how people link this with a user table? I could use a cookie to store the user's id before payment and then get it once the payment is complete, but this would not work with the subsequent recurring payments. 

How do you go about sending the user id when a recurring payment happens?

Any advise would be appreciated.

Hi, I am new here, so hello everyone.

I really need some help with getting Paypal IPN working correctly.

This is what I am trying to do.  I have a user database, when the user logs in, they have the option to upgrade/subscribe to our website.

So when they subscribe and payment is validated, I want a specific field in a specific table updated based on the user's unique ID, not based on [payer_email], so how do I pass on that parameter using IPN?

right now I added the "userId" to a hidden field in the Paypal subscription form named "on1"....

I hope this isn't confusing - would really appreciate your help -  I added code below.
Code: [Select]
<?php

I am trying to get a Paypal IPN working using PHP. I have attached the code I have written that is not working. I have no real way to test it other than nothing is being posted to the databases. The transactions seem to complete with paypal, but I get no information and no emails are generated.

Any help would be much appreciated.

Hi all

I have a quick PayPal IPN question, is this the right group to post the message and does anyone know much about the PayPal IPN?

Thanks
