How to combine two internal PHP functions? - php

Question

I have two code blocks that are PHP functions that do two different things. They are:
<?php
if (!function_exists('UserPhotoDefaultUrl')) {
function UserPhotoDefaultUrl($User) {
$Email = GetValue('Email', $User);
$HTTPS = GetValue('HTTPS', $_SERVER, '');
$Protocol = (strlen($HTTPS) || GetValue('SERVER_PORT', $_SERVER) == 443) ? 'https://secure.' : 'http://www.';
$Url = $Protocol.'gravatar.com/avatar.php?'
.'gravatar_id='.md5(strtolower($Email))
.'&size='.C('Garden.Thumbnail.Width', 50);
if (C('Plugins.Gravatar.UseVanillicon', FALSE))
$Url .= '&default='.urlencode(Asset('http://vanillicon.com/'.md5($Email).'.png'));
else
$Url .= '&default='.urlencode(Asset(C('Plugins.Gravatar.DefaultAvatar', 'plugins/Gravatar/default.gif'), TRUE));
return $Url;
}
}
and...
<?php
class GravatarPlugin extends Gdn_Plugin {
public function ProfileController_AfterAddSideMenu_Handler($Sender, $Args) {
if (!$Sender->User->Photo) {
$Email = GetValue('Email', $Sender->User);
$Hash = md5($Email);
$Sender->User->Photo = 'http://w'.substr($Hash, 0, 1).'.vanillicon.com/'.$Hash.'_200.png';
}
}
}
The first shows the Gravatar image for User avatar in post content of my script (Vanilla forums), and the second one shows the Vanillicons (Vanillicon is similar to Gravatar) of all the users participating in a discussion in the sidebar (under 'In This Discussion'). I hope you get the idea as to what the two code blocks do now?
Using the how-it's-done code in the first code block, I need to modify the second code block to show Gravatar icons of all users participating in a discussion instead of Vanillicons. Can someone who knows PHP help?

<?php
if (!function_exists('UserPhotoDefaultUrl')) {
function UserPhotoDefaultUrl($User) {
$Email = GetValue('Email', $User);
$HTTPS = GetValue('HTTPS', $_SERVER, '');
$Protocol = (strlen($HTTPS) || GetValue('SERVER_PORT', $_SERVER) == 443) ? 'https://secure.' : 'http://www.';
$Url = $Protocol.'gravatar.com/avatar.php?'
.'gravatar_id='.md5(strtolower($Email))
.'&size='.C('Garden.Thumbnail.Width', 50)
.'&default='.urlencode(Asset(C('Plugins.Gravatar.DefaultAvatar', 'plugins/Gravatar/default.gif'), TRUE));
return $Url;
}
}
you class:
<?php
class GravatarPlugin extends Gdn_Plugin {
public function ProfileController_AfterAddSideMenu_Handler($Sender, $Args) {
if (!$Sender->User->Photo) {
$Sender->User->Photo = UserPhotoDefaultUrl($Sender->User); // not sure about the $Sender->User part because it is not displayed
}
}
}
