A Method To View Private Photos in WordPress using PiwigoPress

Hello,

I was interested in using my WordPress installation to pull and display photos from my Piwigo installation.  This is possible using PiwigoPress.  However, PiwigoPress only pulls photos that are public (that is, viewable by 'guest').  I set my Piwigo installation such that it requires a user to log in to see any photos.  (All my albums are marked private.)

So, I modified the PiwigoPress code to log into Piwigo before pulling photos.  This allows WordPress to pull and display photos that are marked as private.

As usual, I will say that I am PHP novice. But, if anyone is interested, the code below works ok. 


Code:

  
//------------------------------------------
//Log in to Piwigo
//------------------------------------------
$Curl_Session = curl_init($piwigo_url . "/ws.php?method=pwg.session.login");
$tmp_fname = tempnam("/tmp", "COOKIE");
curl_setopt ($Curl_Session, CURLOPT_COOKIEJAR, $tmp_fname);
curl_setopt ($Curl_Session, CURLOPT_POST, 1);
curl_setopt ($Curl_Session, CURLOPT_POSTFIELDS, "username=" . $username . "&password=" . $password);
curl_setopt ($Curl_Session, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt ($Curl_Session, CURLOPT_COOKIEFILE,  $tmp_fname);
curl_setopt($Curl_Session, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec ($Curl_Session);
  
//------------------------------------------
//Check Log In Status (optional)
//------------------------------------------
$Curl_Session = curl_init();
curl_setopt ($Curl_Session, CURLOPT_COOKIEJAR, $tmp_fname);
curl_setopt ($Curl_Session, CURLOPT_COOKIEFILE,  $tmp_fname);
curl_setopt($Curl_Session, CURLOPT_TIMEOUT, 5);
curl_setopt ($Curl_Session, CURLOPT_POST, 0);
curl_setopt($Curl_Session, CURLOPT_URL, $piwigo_url . "/ws.php?method=pwg.session.getStatus");
curl_setopt($Curl_Session, CURLOPT_USERAGENT, 'Mozilla/5.0');
curl_setopt($Curl_Session, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($Curl_Session, CURLOPT_FOLLOWLOCATION, 1);    
curl_setopt ($Curl_Session, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt ($Curl_Session, CURLOPT_SSL_VERIFYPEER, 0);

//------------------------------------------
//Get Photo Information
//------------------------------------------
curl_setopt($Curl_Session, CURLOPT_URL, '$piwigo_url . "/ws.php?method=pwg.images.getInfo&format=php&image_id=" . $id);
$response = @curl_exec($Curl_Session);
$status = @curl_getinfo($Curl_Session);  
@curl_close($Curl_Session);

Hello,

What plugin file PiwigoPress do I copy your code?

Thanks.

Re: A Method To View Private Photos in WordPress using PiwigoPress

I placed the code in the file piwigopress.php.  You may need some additional code to make the whole thing work in your implementation.

Re: A Method To View Private Photos in WordPress using PiwigoPress

Hallo,

I have the same installation. (piwigo with no guest login) and I want to try our solution.

But it doesn't work.

First I think there is a ' missing befor ) in the following line.

Code:

curl_setopt($Curl_Session, CURLOPT_URL, '$piwigo_url . "/ws.php?method=pwg.images.getInfo& format=php&image_id=" . $id);

Do you replace some code or do you put it at the end of the file ?
Where is the parameter $username and $password defined ?

Do I need the same login and pwd in WP and Piwigo ?

Is it possible in PiwigoPress_get.php to get a 4 solution?

Many thanks for the greate work

Hello,

I will spend a few minutes and clean up the code.  I will then post it and show and example.

Re: A Method To View Private Photos in WordPress using PiwigoPress

Hello,

Ok, so here is how I did it.  I am not happy with the code and it is not the best way to implement it.  But, for me, it works.

First, here's an example shortcode from a wordpress post:

Code:

[PiwigoPressPrivate id=[photo id]
 url='http://[piwigo user name]:[piwigo password]@[piwigo url]' 
size='xs' desc=1 class='img-shadow']

Fill in [photo id], [piwigo user name], [piwigo password], and [piwigo url]  For example:

Code:

[PiwigoPressPrivate id=45655 url='http://admin_user:password@myurl.com/piwigo/' size='xs' desc=1 class='img-shadow']

Now, I only changed the file, piwigopress.php.  Once again, not the right way to do it.  I did not change pwg_get_contents() at all.  Changing pwg_get_contents would be a better solution.  Perhaps someone could do it and post a cleaner solution.

So, here's the modified piwigopress.php:

Code:

<?php
/*

Plugin URI: http://wordpress.org/extend/plugins/piwigopress/
