jQuery addClass within a foreach loop - javascript

I have a few foreach loops with a trigger and a content div. The intent is for the trigger to be clicked, then addClass to content div, making it visible on screen.
foreach markup
<?php foreach( $posts as $post ) : ?>
<a class="slide-trigger" href="#loc<?php echo $post->ID;?>"><?php the_title(); ?></a>
<span>
<?php
$speakers = get_field('speakers');
?>
<?php if( $speakers ): ?>
<ul class="flat">
<?php foreach( $speakers as $speaker ): ?>
<li>
<a href="<?php echo get_permalink( $speaker->ID ); ?>">
<?php echo get_the_title( $speaker->ID ); ?>
</a>
</li>
<?php endforeach; ?>
</ul>
<?php endif; ?>
</span>
<div class="slide" id="loc<?php echo $post->ID;?>">
<div class="close"></div>
<?php echo $post->post_title;?>
<?php echo $post->post_content;?>
</div>
<?php endforeach; ?>
jQuery
$(".slide-toggle[href^='#loc']").click(function(e){
e.preventDefault();
$(".slide[id^='loc']").addClass("open");
})
$(".close").click(function(){
$(".slide").removeClass("open");
});
What I'm looking for is each slide-toggle to trigger it's slide.
Any thoughts?

The ID is in the href, so just grab it and remove the #loc prefix, then you can select the corresponding slide to open. Also this way, the startsWith selector is no longer required.
$(".slide-toggle[href^='#loc']").click(function(e){
e.preventDefault();
$(".slide[id='loc" + this.href.replace('#loc', '') + "']").addClass("open");
})
Having to parse out the ID, then concatenate like this seems a bit hacky. It would be nicer to use data-* attributes.
Link:
<a class="slide-trigger" data-id="<?php echo $post->ID;?>" href="#loc<?php echo $post->ID;?>"><?php the_title(); ?></a>
Slide:
<div class="slide" data-id="<?php echo $post->ID;?>" id="loc<?php echo $post->ID;?>">
jQuery:
$(".slide-toggle[data-id]").click(function(e){
e.preventDefault();
$(".slide[data-id=" + $(this).data('id') + "]").addClass("open");
})

#MrCode had two great solutions to this. The data-id method is a bit more elegant and what I went with.
Note, the $post->ID is a number which just won't work as an id= - https://css-tricks.com/ids-cannot-start-with-a-number/ - and was causing the issue where things just wouldn't work.
The answer; follow #MrCode's method of using a data attribute. It's elegant and works great w/ the loop.

How to create a seperate popup form for each wordpress post on-click

I have listed my data through a custom-post-type plugin having some custom fields. Below code will display the custom-post-type listing data.
<?php
$args = array(
'post_type' => 'inde_case',
'posts_per_page' => -1
);
query_posts($args);
?>
<ul class="case_study_section1 col-md-12 nopadding">
<?php while ( have_posts() ) : the_post(); ?>
<?php $terms = get_the_terms( get_the_ID(), 'inde_case_category');
if( !empty($terms) ) {
$term = array_pop($terms);
}
?>
<li data-category="<?php echo $term->slug; ?>" class="case_study_img col-md-3 col-sm-6">
<div class="caseSection">
<div class="imagediv"><?php the_post_thumbnail(); ?></div>
<div style="width:100%;float:left;">
<a class="case_study_pdf" href="<?php the_field('linkicon'); ?>" >PDF</a>
<a class="case_study_title" href="<?php the_field('linktext'); ?>" ><?php the_title(); ?></a>
</div>
</div>
</li>
<?php endwhile; ?>
I have properly listed my data having thumbnail and pdf link...etc.
I am trying to create a popup by popup-maker plugin, it has created a class to open a popup. And when I put that class in above code (refer below), in this case only one popup will apply for each post.
<a class="popmake-6981 case_study_pdf" href="<?php the_field('linkicon'); ?>" >PDF</a>
When somebody click on pdf link how can I open a separate popup for each particular post?
Or can I open a specific popup-form using postId or some unique data?
Please Advice.
You can create popups with their [popup] shortcodes, like described here.
Match ID and a trigger class.
<?php while ( have_posts() ) : the_post();?>
<article>
<h2><a class="popmake-post-<?php the_ID();?>" href="<?php the_permalink();?>"><?php the_title();?></a></h2>
<?php echo do_shortcode("[popup id='post-". get_the_ID() ."' size='small' title='". get_the_title() ."']". get_the_content() . "[/popup]");?>
</article>
<?php endwhile; ?>
Beware that you may also need some popup on that page in targeting settings, otherwise they may not initialize.

OwlCarousel2 cannot get jquery to work

I'm doing an slider image by using the plugin OwlCarousel2
I have added the JavaScript and CSS files that they provide on the website.
I'm also setup this on WordPress custom theme. I having a hard time trying to figure out how to setup my own custom Jquery.
Custom animation
jQuery(document).ready(function() {
$(document).ready(function(){
$('.owl-carousel').owlCarousel();
Boolean: false,
Number: 10
});
});
Wordpress Slider Image with Advanced Custom Gallery/Checkbox Fields
<?php $images = get_field('image_carousel'); ?>
<?php $activate_carousel_array = get_field( 'activate_carousel' ); ?>
<?php if( $images ): ?>
<?php if ( $activate_carousel_array ):
foreach ( $activate_carousel_array as $activate_carousel_item ):
echo $activate_carousel_item; ?>
<?php
$images = get_field('image_carousel');
if( $images ): ?>
<div id="hero">
<div class="slider owl-carousel owl-theme">
<?php foreach( $images as $image ): ?>
<div><img src="<?php echo $image['sizes']['large']; ?>" alt="<?php echo $image['alt']; ?>" /></div>
<?php endforeach; ?></div>
</div>
<?php endif; ?>
<?php endforeach; ?>
<?php endif; ?>
<?php endif; ?>
In your code you use
jQuery(document).ready(function() and
$(document).ready(function()
remove one of them.

Lighbox only showing data of the current post in Wordpress

I wanted to show some lightbox funtionality with the use of shortcodes. The code is working fine except for the data shown in the ligthbox. It only shows the data from the latest post in the loop. How can i manage to get lightbox showing the data belonging to the post?
<?php
// Posts are found
if ( $posts->have_posts() ) {
while ( $posts->have_posts() ) :
$posts->the_post();
global $post;
?>
<center>
<div id="su-post-<?php the_ID(); ?>" class="su-post">
<?php if ( has_post_thumbnail() ) : ?>
<a class="su-post-thumbnail" href="<?php the_permalink(); ?>"><?php the_post_thumbnail(); ?></a>
<?php endif; ?>
<div class="su-post-excerpt">
<!-- Shows the button and the hidden lightbox -->
<?php echo do_shortcode ('[su_lightbox type="inline" src="#showInfo"][su_button] Info[/su_button][/su_lightbox]'); ?>
<!-- Shows the lightbox if button is clicked with the data -->
<?php echo do_shortcode ('[su_lightbox_content id="showInfo"][su_meta key="info" default="Geen tekst"][/su_lightbox_content]'); ?>
<?php echo do_shortcode ('[su_lightbox type="inline" src="#showVideo"][su_button] Video[/su_button][/su_lightbox]'); ?>
<?php echo do_shortcode ('[su_lightbox_content id="showVideo"][su_video url="{su_meta key=video}"][/su_lightbox_content]'); ?>
<?php echo do_shortcode ('[su_lightbox type="inline" src="#showFoto"][su_button] Foto[/su_button][/su_lightbox]'); ?>
<?php echo do_shortcode ('[su_lightbox_content id="showFoto"][su_meta key="fotos" default="Geen fotos"][/su_lightbox_content]'); ?>
</div>
</div>
</center>
<?php
endwhile; echo do_shortcode ('[su_lightbox_content id="showInfo"][su_meta key="info" default="Geen tekst"][/su_lightbox_content]');
}
// Posts not found
else {
echo '<h4>' . __( 'Posts not found', 'shortcodes-ultimate' ) . '</h4>';
}
?>
By adding a counter in the while loop and using the variable in the shortcode SRC and ID fields. I needed unique ID's for each post.
$n = 0; /* Outside While Loop */
echo do_shortcode( '[su_lightbox type="inline" src="#showInfo'.$n.'"][su_button] Info[/su_button][/su_lightbox] ');
echo do_shortcode( '[su_lightbox_content id="showInfo'.$n.'"][su_meta key="info" default="Geen tekst"][/su_lightbox_content]' );
$n++; /* Inside While Loop */

Adding a second custom field

I have a custom field 'ExtraCSS' which brings in custom post css using the following code. (It is brought in from a 'have_posts()' loop)
html
<?php $extraCSS = get_post_meta(get_the_ID(),'ExtraCSS',true);?><!-- get specific css for post -->
<article>
<div id="post-<?php the_ID(); ?>" class="img-cell" style="background-image:url('<?php echo $thumbnail_url ?>');" <?php post_class('col-md-12'); ?> >
<a class="linkage" href="<?php the_permalink(); ?>"</a>
</div><!-- /#post -->
<div class="text-cell">
<div class="<?php echo $extraCSS?>" >
<h1><?php the_title(); ?></h1>
<h3><?php the_category(', '); ?></h3>
</div>
</div>
</article>
*EDIT
I want to add 1 more custom field ('BG-align') with either values 'BG-align-L' or 'BG-align-R'. I figured I just add another similar line of code under the current one.
ex.
<?php $extraCSS = get_post_meta(get_the_ID(),'ExtraCSS',true);?>
<?php $BGalign = get_post_meta(get_the_ID(),'BGalign',true);?>
but it doesn't work
According to *edit:
'BGalign' have to be defined in post (by "Add New Custom Field"), otherwise it is just empty.
You could set default value (edit "default-value") if not set in post:
<?php
$BGalign = get_post_meta(get_the_ID(),'BGalign',true);
$BGalign = ( !empty($BGalign) ? $BGalign : "default-value" );
?>
Then remember to echo that new php variable. For example:
<div class="<?php echo $extraCSS . " " . $BGalign; ?>" >
. is dot joining variables into one string
" " is empty space for sure that your both classes names will not be connected

Dynamic jQuery with same ID

Im trying to make a dynamic jQuery function with some help from Advanced Custom Fields in Wordpress. This may not have something to do with the question, but I work in Wordpress with this plugin, anyway.
My code is like this:
<div id="restaurangmeny">
<h2>Vår meny</h2>
<? if( get_field('meny_for_restaurangen') ): ?>
<?php while( has_sub_field('meny_for_restaurangen') ): ?>
<div class="kategori">
<div class="kategorinamn" id="<?php the_sub_field('namn_for_kategorin'); ?>"><?php the_sub_field('namn_for_kategorin'); ?></div>
<div class="matratter" id="<?php the_sub_field('namn_for_kategorin'); ?>">
<? if( get_sub_field('matratter') ): ?>
<?php while( has_sub_field('matratter') ): ?>
<div class="matratt">
<div class="left">
<div class="namn"><?php the_sub_field('namn_pa_matratt'); ?></div>
<div class="beskrivning"><?php the_sub_field('beskrivning_av_matratten'); ?></div>
</div>
<div class="pris"><?php the_sub_field('pris_pa_matratten'); ?>:-</div>
</div>
<?php endwhile; ?>
<?php endif; ?>
</div>
</div>
<?php endwhile; ?>
<?php endif; ?>
</div><!--#restaurangmeny-->
So what I want is when I click on the div called "kategorinamn" I want to div called "matratter" be shown or hidden. That's why I use same id for "kategorinamn" and "matratter" just because these 2 belong together.
Simply, if I click on 1 I want everything that got the same id (1) be shown. If I click on 2 I want everything that got the same id (2) be shown.
I don't know what dynamic jQuery like this is called, but I'm far away from being good with jQuery so that's why I'm asking.
Something like this http://jsfiddle.net/gwK6d/18/, but with jQuery only and that fit's my code above.
1) Import jquery
2) Make sure you are not using the same id for multiple elements
3) Change this bit:
<div class="kategorinamn" id="<?php the_sub_field('namn_for_kategorin'); ?>"><?php the_sub_field('namn_for_kategorin'); ?></div>
<div class="matratter" id="<?php the_sub_field('namn_for_kategorin'); ?>">
To this:
<div class="kategorinamn" id="<?php the_sub_field('namn_for_kategorin'); ?>">
<?php the_sub_field('namn_for_kategorin'); ?>
<div class="matratter" id="<?php the_sub_field('namn_for_kategorin'); ?>">
</div>
4) Declare this function after load:
$(".kategorinamn").click(function(){
$(this).children('.matratter').toggle();
});
