Linking to HR images (again)

G’day Jon,

Interesting use, I like it. I’m going to release a new version in a minute that lets you filter the image path, rather than hacking the plugin. Here’s some sample code, incorporating your code above, and some error logging so that you can see what’s going on:

add_filter('ngg_dlgallery_image_path', function($loRes) {

    $loResSrc =  pathinfo($loRes);
    $loResImgName = $loResSrc['basename'];
    $loResImgDir = basename( $loResSrc['dirname'] );
    list($initialPath,$localPath) = explode("gallery",$loRes);
    $hiRes = $initialPath . "gallery/client-hi-res/" . $loResImgDir ."/" . $loResImgName;

//~ error_log(print_r($loResSrc,1));
error_log("initialPath = $initialPath");
error_log("localPath = $localPath");
error_log("hiRes = $hiRes");
error_log("loRes = $loRes\n");

    return $hiRes;

});

Turn on WP_DEBUG and WP_DEBUG_LOG per Debugging in WordPress, and you’ll get those error log messages in a debug.log file.

When I ran your code, using the filter above, it worked just fine:

initialPath = /var/www/html/wptest/wp-content/
localPath = /hunter-river-shipping/2011-04-30-16-50-34.jpg
hiRes = /var/www/html/wptest/wp-content/gallery/client-hi-res/hunter-river-shipping/2011-04-30-16-50-34.jpg
loRes = /var/www/html/wptest/wp-content/gallery/hunter-river-shipping/2011-04-30-16-50-34.jpg

cheers,
Ross

G’day Jon,

I haven’t added your code to the plugin, I’ve added a filter that lets you add your code to your own plugin, or your theme’s functions.php file, so that you won’t lose your code when you update this plugin 🙂

But I’m planning a premium plugin sometime in the future, and this use case is very interesting; I’ll definitely consider making that a basic feature in the premium plugin.

If you check for updates, under Dashboard on your admin menu, you should find the new version with the filter.

cheers,
Ross

G’day Jon,

Take this block of code and paste it into a file called “ngg-download-hires.php” or similar, and save it into the wp-content/plugins folder. You can then activate it from the WordPress admin plugins page.

<?php
/*
Plugin Name: NextGEN Download HiRes add-on
Description: Filter image paths from NextGEN Download Gallery to divert them to hi-res versions
Version: 0.0.1
*/

add_filter('ngg_dlgallery_image_path', function($loRes) {

    $loResSrc =  pathinfo($loRes);
    $loResImgName = $loResSrc['basename'];
    $loResImgDir = basename( $loResSrc['dirname'] );
    list($initialPath,$localPath) = explode("gallery",$loRes);
    $hiRes = $initialPath . "gallery/client-hi-res/" . $loResImgDir ."/" . $loResImgName;

//~ error_log(print_r($loResSrc,1));
error_log("initialPath = $initialPath");
error_log("localPath = $localPath");
error_log("hiRes = $hiRes");
error_log("loRes = $loRes\n");

    //~ return $hiRes;
    return $loRes;

});

Bam! your first WordPress plugin 🙂

cheers,
Ross

G’day Jon,

Thanks for the expression of gratitude 🙂

For the download gallery template, did you know that you can take a copy into your own theme and customise it there? You can then hack it to bits and change what is output completely, including adding your own JavaScript such as lightboxes. See my blog post, “Creating a custom gallery template for NextGEN Gallery” for how to create custom galleries without changing the core plugin files.

To bring up the whole download gallery in a lightbox, I’d look at writing an AJAX hook that calls do_shortcode() and returns it via AJAX. Most lightboxes can retrieve content from AJAX sources.

cheers,
Ross

G’day @el_duderino,

Interesting approach, I like it! I’ll have a look at how the PclZip class builds its zip file and let you know whether I can do this as a simple filter.

cheers,
Ross

G’day El_Duderino,

I love it when a problem solves itself! Thanks, and thanks for sharing the solution. I’ll include it as a filter call in the next version.

cheers,
Ross

@die_ripps: please start a new support thread when asking for support, don’t add to an existing / resolved thread if you want an answer 🙂

In answer to your question, you can add a template parameter to a shortcode, as described in the installation instructions:

http://wordpress.org/plugins/nextgen-download-gallery/installation/

In the latest NextGEN Gallery you can type in “download” where it asks you to pick a gallery template. v2.0.27 still doesn’t support gallery templates for albums though, so I recommend you stick with v1.9.13 of NextGEN Gallery for now.

cheers,
Ross
