ZenPayPal 2-alpha

Hi, all.

I rewrite my code about zenpaypal plugin, in new version.
I attempt to use the "Paypal REST API PHP SDK".

I need to create a checkout php script receiving posted datas from the form html (wrote by function zenpaypal into zenPaypal.php script).

How to do it for running correctly with zenphoto, and my zenpaypal plugin?

    Great, third party contributionsl like this are always very welcome.

    I don't know the paypal framework and what you specifially need to do with it. But via PHP you can generally check for POST/GET data directy in your main plugin file using

    `if(isset($_POST['your-paypal-form-stuff'`]) {`
    `//here whatever you need to do with the code - Don't forget to sanitize properly!`
    `exitZP(); // to avoid other plugin code being executed afterwards`

    If all can happen on page reload after submitting you can do that within a theme function of the plugin naturally. See for example the `printContactForm()` function from the contact_form plugin.

    Does that help? Or do you mean anything else?
  • ok, thank you.
    I see that! ;)
  • Hi...

    I've one problem, with my script.

    If i test as:


    $ php-7.0 -l zenpaypal.php

    No syntax errors detected in zenpaypal.php

    $ php-7.0 -l zenpaypal/class.ZenPayPal.php

    No syntax errors detected in zenpaypal/class.ZenPayPal.php


    But, when i upload my plugin, the zenphoto website is blank!
    When i delete my plugin, the website run correctly.
    One idea?

    My first lines code into zenpaypal.php:


    <?php<br />

    * zenPaypal -- PayPal ordering support


    * Provides a PayPal ordering form for image print ordering.


    * Price lists can also be passed as a parameter to the zenPaypal() function. See also

    * zenPaypalPricelistFromString() for parsing a string into the pricelist array. This could be used,

    * for instance, by storing a pricelist string in the 'customdata' field of your images and then parsing and

    * passing it in the zenPaypal() call. This would give you individual pricing by image.

    define('ZPP', 'zenpaypal');

    // include class ZPP

    include(__DIR__ .'/'.ZPP.'/class.ZenPayPal.php');

    //include_once(__DIR__ .'/'.ZPP.'/PayPal-PHP-SDK/autoload.php');

    // here declarate new zenpaypal !

    $zenpaypal = new ZenPayPal();

    // needed variables for ZenPhoto

    $option_interface = 'zenPaypalOptions';

    $plugin_author = gettext('Ebrahim Ezzy (Nimbuz), adapted as a plugin by Stephen Billard (sbillard), modified by Stephane HUC (hucste).');

    $plugin_description = gettext('PayPal Integration');

    //$plugin_disable = (version_compare(PHP_VERSION, '5.0.0') != 1) ? gettext('PHP version 5 or greater is required.') : false;

    $plugin_is_filter = 5|ADMIN_PLUGIN|THEME_PLUGIN;

    $plugin_URL = '';

    $plugin_version = $zenpaypal->getPluginVersion();

    Some observations and recommendations.
    • Best use lowercase file names to avoid accidental typos regarding the case. Same for variable names. Function and method names where the case doesn't matter use camelCase.
    • Include classes, functions and filter defines after the $plugin definition.
      Instead `include(__DIR__ .'/'.ZPP.'/class.ZenPayPal.php');` use
      `require_once(SERVERPATH . '/' . USER_PLUGIN_FOLDER . '/zenpaypal/class.ZenPayPal.php');` Not sure if the define of the constant ZPP is really necessary.
    • if `$zenpaypal = new ZenPayPal();` is meant to be used as a global object variable name it accordingly like `$_zenpayapl` or even `$_zp_zenpaypal` (this is how globals should be named internally - sadly ZP does not do this consequently as well in some places ;-))
    • Additionally you zp_register_filter calls might not be correct. If these are not static functions it will not work. If these are methods of the class you have to use static methods like `zp_register_filter('admin_head', 'ZenPayPal::printCSS');`
    The blank page might of course also be caused by the code following that.
