When video content is password protected, video title displays the text "Protected: " before the video Title and the content prints a password form with this text: "This content is password protected. To view it please enter your password below:".

If multiple videos have the same password, one will only have to enter the required password once. Only one password is tracked at a time so if you visit two different videos with two different password, you must re-enter the video password to access content. WordPress saves passwords for maximum 10 days. After this period expires, one must reenter the password again to view the protected content.

  2. Preview - Preview the current state of the Video that's being edited.
  3. Take Over - Lock out the current editor of the Videos and begin editing. (The other user will receive a notification)

The user that has been locked out receives the following dialog, and is no longer able to edit the Video. It can take up to 15 seconds for the current Video editor to be notified that another user has taken over.

Resolving theme related conflicts

For the most part, YouTube Showcase templates will integrate nicely with most WordPress themes. However you may run into issues when the default YouTube Showcase content wrappers do not match your chosen theme or your theme's CSS rules overwrite YouTube Showcase CSS rules.

Theme related issues manifest themselves by;

  • Breaking your layout on YouTube Showcase pages and shifting your sidebars into incorrect positions
  • Some random text getting displayed in header or footer of your site
  • Some sections in plugin pages not getting displayed as in the plugin's demo site.

Theme related issues can potentially affect all single, taxonomy, archive and shortcode pages because YouTube Showcase uses templates of its own to display these pages and it’s impossible for eMDPlugins to know exactly what markup or CSS rules your theme uses.

The following is a Developer level documentation. If you’re unfamiliar with code/templates and resolving potential conflicts, we strongly suggest to hire us or a developer to complete the project for you. Please also note that our complimentary support team is unable to assist with customization per our Support Policy.

There are three methods to resolve theme related issues;

  • Copying and modifying your theme's header.php and footer.php
  • Copying and modifying your theme's page.php
  • Adding custom CSS rules

Modifying header.php and footer.php

  1. Go to your theme's folder -- wp-content/themes/YOURTHEME/
  2. Copy header.php of your theme as header-emdplugins.php
  3. Copy footer.php of your theme as footer-emplugins.php
  4. Remove the conflicting code from header-emdplugins.php and/or footer-emplugins.php.
  5. This will make YouTube Showcase use these newly created header and footer instead of your theme's default header and footer. Save the files. You’re done.

Copying and modifying your theme's page.php

If the issue can not be resolved through simply modifying the header and footer templates, you need to modify your theme's page.php.

Please note that this approach eliminates Your ability:

  • To set page templates for single, archive and taxonomy pages
  • To remove page navigation from archive and taxonomy pages.

from Video Settings, settings page.

To set up this template page:

  1. Duplicate your theme’s page.php file, and name it youtube-showcase.php. This file should be found like this: wp-content/themes/YOURTHEME/youtube-showcase.php.
  2. Open up your newly created youtube-showcase.php in a text editor, or the editor of your choice.
  3. Next you need to find the loop (see The_Loop). The loop usually starts with a:

    <?php if ( have_posts() ) :

    and usually ends with:

    <?php endif; ?>

    This varies between themes. Once you have found it, delete it. In its place, put:

    <?php youtube_showcase_content(); ?>
  4. This will make your theme use YouTube Showcase’s loop instead. Save the file. You’re done.

Adding CSS rules

You add custom CSS rules in the Custom CSS field of Tools tab under Video Settings menu, settings page to overwrite your theme's default CSS. The custom css rules added in the settings are not deleted when your plugin gets updated.

You can learn CSS language by completing the tutorials at w3schools.com

Localization(l10n)

YouTube Showcase can be translated into any language by editing youtube-showcase-emd-plugins.pot and youtube-showcase.pot files.

  • youtube-showcase-emd-plugins.pot file is for the components used in YouTube Showcase.
  • youtube-showcase.pot file is for the YouTube Showcase specific strings that need to be translated.

Follow the steps below to fully translate YouTube Showcase into the desired language:

  1. Copy youtube-showcase-emd-plugins.pot as language specific .po file such as youtube-showcase-emd-plugins-tr_TR.po.
  2. Copy youtube-showcase.pot as language specific .po file such as youtube-showcase-tr_TR.po.
  3. Use your favorite PO file editor and complete translation strings in the .po files you created.
  4. When translations are completed, create .mo file of each .po file.
  5. Create wp-content/languages/youtube-showcase directory
  6. Put translated .mo files and .po files in the directory above to protect them from getting deleted during plugin updates.
  7. Change the language to the translated language from Settings > General > Site Language.
  8. Repeat the process until you get all strings translated
  9. .

Screen Options

Screen Options is displayed as a hanging tab under the toolbar. Click on the Screen Options tab to expand the options available for a particular Screen, check (or uncheck) the desired options, then click the Screen Options hanging tab to collapse the Screen Options. Each screen may have a different set of Screen Options.

Edit page screen options allow the user to decide the edit boxes ,such as taxonomies, relationships or specific boxes such as authors, are presented in the edit area. You can turn on and off the ones that are not needed for a particular edit session.

List page screen options allow users to set the number of records displayed in the list table.

Last Updated: 2016-10-27

Creating Shortcodes

Shortcodes are small blocks of reusable code that can be inserted in a page to generate dynamic and often complex functionality. There is no limit in number of shortcodes that can be created and used. Multiple shortcodes can be used in the same page.

Examples

The following shortcode creates a Video Grid Gallery page with videos of Categories category.

[video_grid filter="tax::category::is::YOUR TAXONOMY VALUE;"]

The following shortcode creates a Video Grid Gallery page with videos of Categories category.

[video_grid filter="attr::blt_title::is::YOUR ATTRIBUTE VALUE;"]

The following shortcode creates a Video Grid Gallery page with videos of Categories category where Title is blt_title .

[video_grid filter="attr::blt_title::is::YOUR ATTRIBUTE VALUE;tax::category::is::YOUR TAXONOMY VALUE;"]

The following shortcode creates a Video Grid Gallery page with the published videos of Categories category where Title is blt_title in descending order by comment count, displaying 15 videos with no pagination.

[video_grid filter="attr::blt_title::is::YOUR ATTRIBUTE VALUE;tax::category::is::YOUR TAXONOMY VALUE;misc::post_status::is::publish;misc::order::is::DESC;misc::posts_per_page::is::15;misc::has_pages::is::false;misc::orderby::is::comment_count;"]

Note: Replace YOUR ATTRIBUTE VALUE with the value stored for that attribute and YOUR TAXONOMY VALUE with the slug of the corresponding taxonomy value.

Customizations

YouTube Showcase offers extensive customization options from plugin settings, settings page. The following customizations can be done without changing your theme's template files:

  • Enable or disable all fields, taxonomies and relationships from backend and/or frontend
  • Set any entity and/or archive base slug
  • Set the page template of any entity, taxonomy and/or archive page to sidebar on left, sidebar on right or no sidebar (full width)
  • Hide the previous and next post links on the frontend for single posts
  • Hide the page navigation links on the frontend for archive posts
  • Display or hide any custom field
  • Display any side bar widget on plugin pages using EMD Widget Area
  • Set custom CSS rules for all plugin pages including plugin shortcodes

If your customization requirements are more complex and can not be resolved through the list of options provided above, you need to implement advanced customization techniques.

Advanced Customizations

Note:The following is a Developer level documentation. If you’re unfamiliar with code/templates/localization and resolving potential conflicts, we strongly suggest to hire us or a developer to complete the project for you. Please also note that our complimentary support team is unable to assist with customization per our Support Policy.

YouTube Showcase advanced customization can be done on 3 different areas;

  • Look & Feel - changing layout and overall presentation of content
  • Functionality - adding, deleting or modifying existing plugin functionality
  • Strings - changing the field names

Plugin customization can be implemented by using 4 different methods:

Customizing functionality

If you'd like to modify the functionality, you need to modify the plugin design (sold separately) using WP App Studio ProDev API access (sold separately and monthly development plans are available).

Customizing look & feel

If you like to customize how HTML elements are to be displayed on screen, you can add custom CSS rules with higher specificity to your theme's style.css file.

If you'd like to customize layouts of YouTube Showcase, Please follow the steps below:

  1. Create "emd_templates" directory under your theme's directory.
  2. Copy the layout files that you want to customize into "emd_templates" directory which you created in step 1 from PLUGIN-ROOT/layouts directory
  3. Modify the file based on your needs

The layout files you added in the "emd_templates" has always precedence over the plugin's layout files. If the customized files get deleted, the layouts which came with your plugin are displayed. We recommend that you create a child theme if you'd like to minimize the risk of accidental deleting of the "emd_templates" directory because of theme updates.

The following layout file types can be customized:

  • Single view page
  • Archive view page
  • Taxonomy view page
  • Search form result page
  • Standard list page
  • Integration page
  • Org chart record and tooltip layout page

Customizing strings

YouTube Showcase labels and messages can be customized to better match your needs through language files. The customization is very similar to localization but recommended for US English users only. If your language is different than US English, you should localize instead of customize. The customization can be done for the strings included in youtube-showcase-emd-plugins.pot and youtube-showcase.pot files.

The following steps cover the string customization of labels and messages.

  • youtube-showcase-emd-plugins.pot file is for the translatable strings of components used in YouTube Showcase.
  • youtube-showcase.pot file is for the YouTube Showcase specific strings that need to be translated.

Follow the steps below to fully customize YouTube Showcase labels and messages:

  1. Copy youtube-showcase-emd-plugins.pot as language specific .po file such as youtube-showcase-emd-plugins-en_US.po.
  2. Copy youtube-showcase.pot as language specific .po file such as youtube-showcase-en_US.po.
  3. Use your favorite PO file editor or plugin and complete customization of strings in the .po files you created.
  4. When customization are completed, create .mo file of each .po file.
  5. Create wp-content/languages/youtube-showcase directory.
  6. Put customized .mo files and .po files in the directory above to protect them from getting deleted during plugin updates.
  7. Repeat the process until you get all strings customized. If you do not need a string to be customizes, leave it as it is.

All customization can be done by yourself or emarketdesign.com. Open a support ticket, if you prefer us to do the customization for you.
