Is it possible to use the_content() excluding the galleries? I want to make this because I need the gallery displayed with flexslider. I already integrate flexslider. If I want to show the content of the post, for example: some text, separated images and of course a gallery. It will display the gallery with flexslider and then the content with the text, images and the gallery again. I don't want the gallery duplicated.
<div class="entry-content">
<?php $gallery = get_post_gallery( get_the_ID(), false );?>
<div class="flexslider flexslider-gallery">
<ul class="slides slides-gallery">
<?php foreach( $gallery['src'] AS $src ){ ?>
<li>
<img alt="Gallery image" src="<?php echo $src; ?>" />
</li>
<?php } ?>
</ul> <!-- end .slides -->
</div> <!-- end .flexslider -->
<?php the_content(); ?>
</div><!-- .entry-content -->
Ok here is the solution:
Add to functions.php
function remove_shortcode_from($content) {
$content = strip_shortcodes( $content );
return $content;
}
and then call it when you need, in my case in content-gallery.php:
add_filter('the_content', 'remove_shortcode_from');
the_content();
remove_filter('the_content', 'remove_shortcode_from')
Two ways:
1) The WordPress Gallery is contained in a div with class .gallery. If flexsider does not also use that class, you could simply set your CSS to:
.gallery { display: none; }
2) You could get the content with get_the_content, parse it using a DOM parser and delete the Gallery.
Option #1 is less efficient, but avoids the complexity of parsing the DOM.
Neither method is guaranteed to work if the site is use a non-standard gallery plugin that is creating non-WP HTML.

I have a Wordpress page, in which my images appears on left and my text appears on right. The images fall down under the text when the page is loaded on mobile screen. I have a PHP code to achieve all of that, basically it switchs image and text places, and attributes left or right to each.
But since this is in place, I have trouble adding images' captions. When I want to add images' captions in my Wordpress admin, the caption doesn't come under the image but it comes up my text article (so, on the right part of the page). I guess my PHP code attributes automaticaly this place to every text.
I need the images' captions to be under my images, and I guess this has a lot to do with that PHP code you can see below. But I don't know how to fix that.
Here is my PHP:
<?php if (have_posts()): ?>
<div class="container">
<?php while(have_posts()): the_post(); ?>
<div class="row">
<div id="content_post">
<div class="col-lg-push-5 col-lg-6 col-md-push-6 col-md-6 col-sm-12 col-xs-12 ">
<?php
//get content from back office , filter imgs except featured img to place them later in <div id='img_content_right'>
$content2 = get_the_content();
$removed_imgs = array();
$content2 = preg_replace_callback('#(?!<img.+?id="featured_img".*?\/>)(<img.+? />)#',function($r) {
global $removed_imgs;
$removed_imgs[] = $r[1];
return '';
},$content2);
//add filter to the_content to strip images except img_menu et featured_img
add_filter('the_content', 'strip_images',2);
function strip_images($content){
$content=preg_replace('/(?!<img.+?id="img_menu".*?\/>)(?!<img.+?id="featured_img".*?\/>)<img.+?\/>/','',$content);
return $content;
}
the_content();
?>
</div>
</div>
<div class="col-lg-pull-6 col-lg-5 col-md-pull-6 col-md-6">
<div id='img_content_right'>
<?php
//append the images stripped from content
foreach($removed_imgs as $img){
echo $img; } ?>
</div>
</div>
</div>
</div>
<?php endwhile; ?>
<?php endif; ?>
To appropriately handle the caption you need to get the attachment post object and then look at the post_excerpt.
There's a function in WordPress get_attached_media, which will list all of the images within a posts content. This be easier to iterate over then using regex to find the images.
I would like that my php detects seperatly images (media) and text, from a same wordpress post, in regard to display them in different columns. I am using Bootstrap, and I would like different display of each (text and image) according to the screen size.
Here is a code I have that displays all of the content of my post (image and text) at once, it works perfectly :
<div class="container">
<?php if (have_posts()): ?>
<div class="container">
<?php while(have_posts()): the_post(); ?>
<div class="row">
<div class="col-xs-12 col-md-12 col-lg-12">
<?php the_content(); ?>
</div>
</div>
<?php endwhile; ?>
</div>
<?php endif; ?>
</div>
I would like the same way of loading content but instead of having just
<?php the_content(); ?>
I would like something like this to place text and image (of same post) in different div class:
<?php the_image(); ?>
AND
<?php the_text(); ?>
I know this is wrong code but I am trying to be clear in my explanation. I need that my client does not touch any of code, also shortcode in Wordpress post. Any input or advice would be very appreciated!
Many thanks!
Thank you for your answer! Lars Beck, you solved my problem!
Here is the code I was looking for:
<?php
//get content from back office , filter imgs except featured img to place them later in <div id='img_content_right'>
$content2 = get_the_content();
$removed_imgs = array();
$content2 = preg_replace_callback('#(?!<img.+?id="featured_img".*?\/>)(<img.+? />)#',function($r) {
global $removed_imgs;
$removed_imgs[] = $r[1];
return '';
},$content2);
//add filter to the_content to strip images except img_menu et featured_img
add_filter('the_content', 'strip_images',2);
function strip_images($content){
$content=preg_replace('/(?!<img.+?id="img_menu".*?\/>)(?!<img.+?id="featured_img".*?\/>)<img.+?\/>/','',$content);
return $content;
}
the_content();
?>
<div id='img_content_right'>
<?php
//append the images stripped from content
foreach($removed_imgs as $img){
echo $img;
}
?>
</div>
There is no way, to separate out images from the content section if they have just been included as part of the content.
Wordpress has featured image functionality built in for you. so you can use the_post_thumbnail() to echo out the image. Maybe this question can help you Wordpress featured image code
If this isn't enough for you and you need more flexibility you might want to look at advanced custom fields plugin - https://www.advancedcustomfields.com/ it makes it easy for you to add your own fields of any type you want.
I am using 'Aqua Resizer' (aq_resizer.php) to resize my thumbnails on my Wordpress site. My posts are made from a loop in single.php with
<?php get_template_part( 'content', 'single' ); ?>
This pulls from content-single.php which has the code for my posts
HTML
<div id="post-<?php the_ID(); ?>" <?php post_class('col-md-12'); ?> >
<div>
<h2><?php the_title(); ?></h2>
<h3><?php the_category(', '); ?></h3>
<?php the_content(); ?>
</div>
<?php
$thumb = get_post_thumbnail_id();
$img_url = wp_get_attachment_url( $thumb,'full' ); //get full URL to image (use "large" or "medium" if the images too big)
$image = aq_resize( $img_url, 1200, 720, true ); //resize & crop the image
?>
<?php if($image) : ?>
<img class="img-responsive" src="<?php echo $image ?>"/>
<?php endif; ?>
</div><!-- /#post -->
Everything works fine (the resizer function works on the featured post which is brought in with <?php the_content(); ?>. The image scales up/down as the window resizes
The effect works because class="img-responsive" is applied to the featured-image of the post.
I have images in the content of the post. I want them to act the same way (right now they are just brought in at their original size) I need the class img-responsive to be applied to the images in <?php the_content(); ?>
Applying the CSS classes to images can be done from within the post itself, just edit the image and put CSS class img-responsive.
If you cannot edit/modify posts (or it is just too much work) then second option is to write a small code snippet in your theme's custom function.php file (this is true only when you display post in your loop):
<?php
the_post_thumbnail('thumbnail', array('class' => 'img-responsive'));
See https://codex.wordpress.org/Function_Reference/the_post_thumbnail for more details.
And the third option is to use jQuery in your header.php file, this way all images on page will get responsive class (however this may not be what you want, especially if you have backgrounds, logos, menu images, etc. and it will require JavaScript to be enabled in client's browser):
<script type="text/javascript">
jQuery(function() {
jQuery(img).addClass('img-responsive');
});
</script>
The last option I can think of, is by using pure CSS:
.content img { height: auto; max-width: 100%; }
Where .content is the area that contains your post content.
Note: You may also want to override the .wp-caption class as well like so.
.wp-caption { width: auto !important; }
I want to show limit latest post of WordPress in main page. I'm using WordPress APIs and functions to show that, but after that get_the_content() remove and escape all of seved tags and my posts don't show correctly such as editor tags.
This function escape HTML tags:
<ul style="list-style: none;margin:5px" class="latest-posts">
<!-- LOOP START -->
<?php $the_query = new WP_Query( 'showposts=3' ); ?>
<?php while ($the_query -> have_posts()) : $the_query -> the_post(); ?>
<!-- THIS DISPLAYS THE POST THUMBNAIL, The array allows the image to has a custom size but is always kept proportional -->
<li> <?php the_post_thumbnail( array(100,100) );?></li>
<!-- THIS DISPLAYS THE POST TITLE AS A LINK TO THE MAIN POST -->
<li>
<a href="<?php the_permalink() ?>">
<?php the_title(); ?>
</a>
</li>
<!-- THIS DISPLAYS THE EXCERPT OF THE POST -->
<li>
<?php echo mb_substr(get_the_content(), 0, 1200).' ...'; ?>
</li>
<!-- READ MORE LINK -->
<li>more ...</li>
<?php endwhile;?>
<!-- LOOP FINNISH -->
</ul>
There are basically three possibilities how to output the excerpt of the post content.
with the excerpt() function, to output the content of the excerpt field in post editor, if it's not filled it will display the first 55 words of the post content ( use excerpt_length filter to control the length of the excerpt ).
to use the <!--more--> quicktag, the_content() tag will only show the excerpt up to the <!--more--> quicktag. That quicktag will not work in single pages templates.
to manually strip HTML from post content and to show custom excerpt. One way to do that is to use wp_filter_nohtml_kses() function:
echo mb_substr( wp_filter_nohtml_kses( get_the_content() ), 0, 1200 );
All methods above will strip the HTML from post content. To include HTML in excerpts use excerpt field in post editor, WordPress will preserve HTML you included in post editor. There are also some plugins like Advanced Excerpt that will create excerpt from content and preserve html, but I don't believe that there is a bullet proof way of doing that.
I'm quite new to wordpress, so bear with me. I have a site up and running allowing me to add content dynamically, the only problem is styling each post. I'm looking to wrap posts in a div, so images would be wrapped in one div and text posts would be wrapped in another, if that makes sense?Here's some code I've been using:
<?php if ( in_category('photos') ) { ?>
<div id="testing">
<?php } else { ?>
<div id="test-2">
<?php } ?>
The only problem with this is that it wraps all posts in a given category and doesn't put a closing '< / div >' after the content, if that makes sense?
Well, the only reason you're not getting any closing </div>s is because you're not putting it anywhere in your php.
This should work:
<?php while( have_posts() ) : the_post()
if( in_category( 'photos' ) { ?>
<div id="testing">
// All your post content and whatnot
<?php the_content(); ?>
</div>
<?php } else { ?>
<div id="test-2">
// All your post content
<?php the_content(); ?>
</div>
<?php }
endwhile; ?>
If you don't write complete markup in your theme files, you can't possibly expect Wordpress, or PHP, to automatically close your HTML tags.
"if that makes sense" No it doesn't really make sense as Wordpress by default adds a CSS-class for every category and tag to the surrounding div. If that is not the case in your theme, use the function post_class() to add the CSS-classes to your div.
See the post_class()-documentation for usage examples.
