Trigger Wordpress Image Gallery Via Button/Link - wordpress

I want to open a default Wordpress gallery in a lightbox with a button or link and hide the gallery thumbnails on the page. How can I achieve that?
Gallery shortcode: [gallery ids="55,67"]
Thanks in advance.

You can try like this.
<style>
.hiddengallery{
display:none;
}
</style>
<button class="showgallery" >click here</button>
<div class="hiddengallery">
// add lightbox code here
<?php echo do_shortcode('[gallery ids="55,67"]');?>
</div>
<script>
jQuery(document).on("click",".showgallery", function (){
jQuery(".hiddengallery").show();
});
</script>

I want to use the image title (meta data value from below screenshot) to auto display as each images caption underneath each image. Also for Accessibility purposes auto assign this meta value as the 'alt=""' value by default?
Current template code:
<link rel="stylesheet" href="#App.Path/dist/lib/blueimp/css/blueimp-gallery.min.css" data-enableoptimizations="true" />
<script type="text/javascript" src="#App.Path/dist/lib/blueimp/js/blueimp-gallery.min.js" data-enableoptimizations="bottom"></script>
<link rel="stylesheet" href="#App.Path/dist/app/view.css" data-enableoptimizations="true" />
#if(#Dnn.User.IsSuperUser)
{
#Content.Toolbar
} else {
#Edit.Toolbar(Content, actions: "edit,add")
}
<div id="blueimp-gallery-items-#Dnn.Module.ModuleID" style="display:none;">
#foreach (var pic in AsAdam(Content, "Images").Files)
{
<a href="#pic.Url?w=#App.Settings.CarouselImageWidth&h=#App.Settings.CarouselImageHeight&mode=crop" title="#(((dynamic)pic.Metadata).Title)" data-gallery="#blueimp-gallery-#Dnn.Module.ModuleID">
#(((dynamic)pic.Metadata).Title)
</a>
}
</div>
#* this is the rotator element *#
<div id='blueimp-gallery-#Dnn.Module.ModuleID' class='blueimp-gallery blueimp-gallery-carousel' data-carousel='true' data-start-slideshow="true">
<div class='slides'></div>
<h3 class='title'></h3>
<a class='prev'>‹</a>
<a class='next'>›</a>
<a class='play-pause'></a>
<ol class='indicator'></ol>
</div>
<script type="text/javascript">
$(document).ready(function () {
// initialize the carousel gallery
blueimp.Gallery($('[data-gallery="#blueimp-gallery-#Dnn.Module.ModuleID"]').get(), {
container: '#blueimp-gallery-#Dnn.Module.ModuleID',
carousel: true
}
);
});
</script>
Also note that when I click on meta data tag, the following error message pop up appears:
Note: Version: 9.2.0
UPDATE:
Changing "Image Metadata" to "ImageMetadata" worked thx.
Still having trouble adding alt tag to each image. title shows but when I set alt to same it doesn't?
<div id="blueimp-gallery-items-#Dnn.Module.ModuleID" style="display:none;">
#foreach (var pic in AsAdam(Content, "Images").Files)
{
<a href="#pic.Url?w=#App.Settings.CarouselImageWidth&h=#App.Settings.CarouselImageHeight&mode=crop" title="#(((dynamic)pic.Metadata).Title)" alt="#(((dynamic)pic.Metadata).Title)" data-gallery="#blueimp-gallery-#Dnn.Module.ModuleID">
#(((dynamic)pic.Metadata).Title)
</a>
}
</div>
So you're asking a few things at the same time.
number 1: to use the title you want to check if the image has metadata, and if yes, use that. This code should help (pic is the image-variable in your loop) :
#(pic => !pic.HasMetadata ? "" : ((dynamic)pic.Metadata).Title)
number 2 seems to be an issue in the configuration. as far as I can see, the metadata-button in the default toolbar works. I checked the internal and the field-configuration is wrong - you should change it from "Image Metadata" to "ImageMetadata"

How to go back to home page in wordpress project?

Here, when i click Go Back button it perfectly goes to back page
<script>
function goBack() {
window.history.back();
}
</script>
<div class="back">
<button onclick="goBack()" class="btn btn-voilet" > << Go Back</button>
</div>
Now if i click back to curriculum button, it doesnt go back to home page can someone help me do it,
<script>
function back_to_curriculum() {
window.history.home();
}
</script>
<div class="home">
<button onclick="back_to_curriculum()" class="btn btn-voilet" > << Back to Curriculum</button>
</div>
You can take advantage of Wordpress' home_url() function to get the Home URL of the site, then use Javascript to navigate there:
<script>
function back_to_curriculum() {
window.location.href = '<?php echo home_url(); ?>';
}
</script>

Jquery script to show/hide content with the_ID?

I have a HTML code:
<div class="content">
blablabla
</div>
Show hidden content
Hide content
I need Jquery code to show or hide div "content", but i need that code to work with <?php the_ID (); ?> its will be used in posts loop so i need unicue ID's.
Ex.: <div class="content-<?php the_ID (); ?>">
Any ideas?
Try this:
$('.show').click( function(){
$('.content-<?php the_ID (); ?>').show();
});
$('.hide').click( function(){
$('.content-<?php the_ID (); ?>').hide();
});

WordPress: Setting up a page that uses post images to link to post category

I came across this site: http://www.jfletcherdesign.com.
I want to replicate how the home page shows the featured image of all of his posts and that when you click on the image you drill down into in the specific post. I also want to replicate how you are able to click forward and next with an image to the corresponding post within a category.
Can someone please point me in the right direction for setting up this functionality?
Bonus points if you can point me to the jQuery plugin that is being used for the rollover effect on his category page.
Thanks!
That site is based on the Imbalance theme by WPShower. It's a free theme so you can download it and check out all the source code. That should answer your first question.
To get images that act as pagination to the previous and next posts all you need to do is use the get_adjacent_post function. You can use something like the code below to set it up to link an image. Stick it in the bottom of your single.php or wherever you want the pagination to appear.
<?php
$prev_post = get_adjacent_post(true, '', true);
$next_post = get_adjacent_post(true, '', false);
?>
<?php if ($prev_post) : $prev_post_url = get_permalink($prev_post->ID); ?>
<a class="previous-post" href="<?php echo $prev_post_url; ?>"><img src="www.site.com/previous-image.png" alt"previous post" /></a>
<?php endif; ?>
<?php if ($next_post) : $next_post_url = get_permalink($next_post->ID); ?>
<a class="next-post" href="<?php echo $next_post_url; ?>"><img src="www.site.com/next-image.png" alt"next post" /></a>
<?php endif; ?>
Now for the jQuery rollover, it is pretty simple:
$(document).ready(function() {
$('.article').mouseenter(function() {
$(this).find('.article-over').show();
});
$('.article').mouseleave(function() {
$(this).find('.article-over').hide();
});
$('.article').hover(
function() {
$(this).find('.preview a img').stop().fadeTo(1000, 0.3);
},
function() {
$(this).find('.preview a img').stop().fadeTo(1000, 1);
}
);
});
Which acts on the following HTML markup generated by the theme:
<li class="article li_col1" id="post-1234">
<div class="preview">
<img width="305" height="380" src="http://www.site.com/image/src.jpg" class="attachment-background wp-post-image" alt="" title="Cool Post">
</div>
<div class="article-over">
<h2>Cool Post</h2>
<div class="the-excerpt">
<p>Blah blah blah this is a post excerpt...</p>
</div>
</div>
</li>
So basically when you first go to the site, for all the items except the first, all you see is the .preview div that holds the category image. The .article-over div is absolutely positioned over the .preview div but has a style of display:none so that you can't see it.
When the mouseenter event is fired, the .article-over div is displayed via show(), and the image inside .preview fades out to an opacity of 0.3 allowing you to see the .preview div's black background behind it. When the mouse leaves, .article-over is hidden, and the .preview image fades back to fully opaque.
If you're still stuck let me know and I'll try to explain further.

Popup doesn't work in Wordpress post

I have a HTML form which is a popup. When the user click the button, form will get appear at the same page.
But this code doesn't work in Wordpress post:
<a href="javascript: void(0)" onClick="OpenPopup();">
<img border="0" src="submit.jpg">
</a>
What should I do for this?
Iexplore doesn't support onClick, may be you can do this by creating a jQuery function :
Add ID first:
<img id='image_id' border="0" src="submit.jpg"/>
Then, jQuery function:
<script>
$(document).ready(function(){
$('#image_id').click(function(){
OpenPopup();
});
});
</script>
