I need if else statement with the following values using ACF Plugin.
I have a field named "headline":
<?php if ( get_field( 'headline') ) { ?>
<a href="<?php the_permalink(); ?>" rel="bookmark">
<img src="<?php the_field( 'headline' ); ?>" />
</a>
<?php } ?>
Wordpress Title Code:
<a href="<?php echo esc_url(get_permalink()); ?>">
<?php echo get_the_post_thumbnail(get_the_ID(), $thumbnail_size , array('alt' => get_the_title(),'title' => '')); ?>
</a>
What I want: If field one headline is available then show field one otherwise show the second code of wordpress title
<?php $headline = get_field( 'headline'); ?>
<?php if($headline) { ?>
<a href="<?php the_permalink(); ?>" rel="bookmark">
<img src="<?php the_field( 'headline' ); ?>" />
</a>
<?php } else { ?>
<a href="<?php echo esc_url(get_permalink()); ?>">
<?php echo get_the_post_thumbnail(get_the_ID(), $thumbnail_size , array('alt' => get_the_title(),'title' => '')); ?>
</a>
<?php } ?>
Try this code:
<?php if(!empty(get_field( 'headline'))) { ?>
<a href="<?php the_permalink(); ?>" rel="bookmark">
<img src="<?php the_field( 'headline' ); ?>" />
<?php } else { ?>
<a href="<?php echo esc_url(get_permalink()); ?>">
<?php echo get_the_post_thumbnail(get_the_ID(), $thumbnail_size , array('alt' => get_the_title(),'title' => '')); ?></a>
<?php } ?>

In my blog site everything is working fine but on some posts images are not coming in the image src i am getting this error:
<img class="lazy _single__img" alt="" data-src="<br />
<b>Notice</b>: Trying to access array offset on value of type bool in <b>/var/www/fisharoma/wp-content/themes/wisledge2/template-parts/single.php</b> on line <b>19</b><br />
" src="<br />
<b>Notice</b>: Trying to access array offset on value of type bool in <b>/var/www/fisharoma/wp-content/themes/wisledge2/template-parts/single.php</b> on line <b>20</b><br />
">
According to the error something is wrong in my single.php line 20, but i can't figure out what am doing wrong.
Here is my single.php
<?php
$categories = get_the_category();
if (empty($categories) || !count($categories)) {
return;
}
$term = $categories[0];
?>
<article id="entry-<?php the_ID(); ?>" <?php post_class('_single'); ?>>
<nav class="_path">
<a class="_path__link" href="https://fisharoma.com/">Home ></a>
<a class="_path__link" href="<?php echo get_category_link($term->term_id); ?>"><?php echo $term->cat_name; ?> <?php _e('', 'wisledge'); ?></a>
</nav>
<?php the_title('<h1 class="_single__title">', '</h1>'); ?>
<?php // the_post_thumbnail('large', ['class' => '_single__img']); ?>
<img
class="lazy _single__img"
alt="<?php echo get_post_meta(get_post_thumbnail_id(), '_wp_attachment_image_alt', true); ?>"
data-src="<?php echo wp_get_attachment_image_src(get_post_thumbnail_id(), 'large')[0]; ?>"
src="<?php echo wp_get_attachment_image_src(get_post_thumbnail_id(), 'large')[0]; ?>"
/>
<div class="_single__content">
<?php get_template_part('template-parts/share'); ?>
<div class="_meta">
<span class="_meta__by"><?php _e('By ', 'wisledge'); ?></span>
<?php the_author(); ?>
<?php if (get_the_time() != get_the_modified_time()) :?>
<span class="_meta__updated"><?php _e('Updated', 'wisledge'); ?></span>
<?php
/*
<!-- <time class="_meta__time" datetime="<?php the_modified_time('c'); ?>"><?php the_modified_time(get_option('date_format')); ?></time> -->
*/
?>
<time class="_meta__time"><?php the_modified_time(get_option('date_format')); ?></time>
<?php endif; ?>
</div>
<?php the_content(); ?>
</div>
</article>
Try wrapping your image with a check condition first:
if(wp_get_attachment_image_src(get_post_thumbnail_id(), 'large')){
?>
<img
class="lazy _single__img"
alt="<?php echo get_post_meta(get_post_thumbnail_id(), '_wp_attachment_image_alt', true); ?>"
data-src="<?php echo wp_get_attachment_image_src(get_post_thumbnail_id(), 'large')[0]; ?>"
src="<?php echo wp_get_attachment_image_src(get_post_thumbnail_id(), 'large')[0]; ?>"
/>

i would like to display a different logo in home page (with ACF).
i try with this code but it doesn't work :
<?php if(is_home()){ ?>
<?php $logo = get_field( 'logo', 'option' ); ?>
<?php if ( $logo ) { ?>
<a href="<?php echo home_url(); ?>" class="navbar-brand">
<img src="<?php echo $logo['url']; ?>" alt="" />
</a>
<?php } ?>
<?php } else { ?>
<?php $logo_footer = get_field( 'logo_footer', 'option' ); ?>
<?php if ( $logo_footer ) { ?>
<a href="<?php echo home_url(); ?>" class="navbar-brand">
<img src="<?php echo $logo_footer['url']; ?>" alt="" />
</a>
<?php } ?>
<?php } ?>
Do you have any tips ?
thank you
If you have set the homepage in Settings->Reading->Your homepage, you'll have to use is_front_page() instead of is_home().
More information here: https://wordpress.stackexchange.com/a/30389
Add This code into your php file where you want to add it.
i hope its working.
<?php
$logo = get_field( 'logo', 'option' );
$logo_footer = get_field( 'logo_footer', 'option' ); ?>
<?php if ( $logo ) { ?>
<a href="<?php echo home_url(); ?>" class="navbar-brand">
<img src="<?php echo $logo['url']; ?>" alt="" />
</a>
<?php } ?>
<?php if ( $logo_footer ) { ?>
<a href="<?php echo home_url(); ?>" class="navbar-brand">
<img src="<?php echo $logo_footer['url']; ?>" alt="" />
</a>
<?php } ?>
I have a logo and I want it to redirect to a homepage when the user is logged in or to a register site when the user is not logged in.
Here is my code:
<strong class="logo">
<?php if (is_user_logged_in()) ?>
<a href="http://test/register/">
<?php else ?>
<a href="<?php echo home_url();?>">
<img id="logo_img" title="<?php bloginfo('name'); ?>" src="<?php echo $logo_path; ?>" alt="<?php bloginfo('name'); ?>">
I'm using Wordpress. It says unexpected "else".
You are not doing your if / else statements correctly:
<strong class="logo">
<?php if (is_user_logged_in()) { ?>
<a href="http://test/register/">
<?php } else { ?>
<a href="<?php echo home_url();?>">
<?php } ?>
<img id="logo_img" title="<?php bloginfo('name'); ?>" src="<?php echo $logo_path; ?>" alt="<?php bloginfo('name'); ?>">
if you want to use this in a way for no brackets you have to do something like this:
<strong class="logo">
<?php
if (is_user_logged_in())
echo '<a href="http://test/register/">';
else
echo '<a href="'.home_url().'">';
?>
<img id="logo_img" title="<?php bloginfo('name'); ?>" src="<?php echo $logo_path; ?>" alt="<?php bloginfo('name'); ?>">
<strong class="logo">
<?php
if (is_user_logged_in())
{
echo '<a href="http://demo.com/register-path/">';
}
else
{
echo '<a href="'.home_url().'">';
}
echo '<img src="logo-path.png"></a>';
?>

I have a custom field named "Thumbnail" that I use currently to display thumbnails for my posts on my Wordpress site. I recently bought a new template and can't seem to get the code to display this to work. I think it's because the new template is using an array instead.
Currently, I just have to put:
<img src="<?php echo get_post_meta($post->ID, Thumbnail, true); ?>"/>
and it displays perfectly. So here is the code I believe I need to change in the new site:
<?php if($counter <= $big_count): ?>
<?php if($counter == $big_count) { $last = ‘block-item-big-last’; } else { $last = ”; }?>
<div class="block-item-big <?php echo $last; ?>">
<?php if($images && has_post_thumbnail()): ?>
<?php $image = wp_get_attachment_image_src(get_post_thumbnail_id($post->ID), ‘widget-image’); ?>
<div class="block-image"><a href=’<?php the_permalink(); ?>’ title=’<?php the_title(); ?>’><img src="<?php echo $image[0]; ?>" alt="<?php the_title(); ?>" width=’290′ height=’160′ />
Looks like it’s using an array? But I don’t know enough about code to get this to work. I tried to put my code in the img tag of the last line above but pretty sure I need to change something else.
Please help! Thanks.
**UPDATE**
Thanks for the info #Ehs4n and #Tim! Still no luck but I decided to try a simpler approach by removing that part of the code that checks for the array. I feel like I am close. Here is what I have now.
<?php if (in_category('movies') ): ?>
<div class="block-item-big-<?php echo $last; ?>">
<div class="block-image"><a href='<?php the_permalink(); ?>' title='<?php the_title(); ?>'><img src="<?php echo get_post_meta($post->ID, Thumbnail, true); ?>" alt="<?php the_title(); ?>"/></a><?php echo $icon; ?></div>
But the still no thumbnail shows up? Not sure what I am missing, I have a Custom Field called Thumbnail with the appropriate link to the picture on the server on that post. It even works correctly when I put in the actual URL in for the img src to that picture but when I put in the code...
<?php echo get_post_meta($post->ID, Thumbnail, true); ?>
it is like it does not understand that. Firebug tells me that the src is empty, it is like it is not returning Thumbnail Custom Field as it should be?

Throw in a print_r($image) to find out if Image is an array. What result is coming out of using image[0]?
If you are using custom fields to store thumbnail paths, why are you confused with the code used in your template.
You can still use your old code to get the image
<?php echo get_post_meta($post->ID, Thumbnail, true); ?>
Looking at your template's code, it uses Wordpress function wp_get_attachment_image_src() which takes three parameters, $attachement_id - to pass id of that media, $size - media size / image size to display & third optional $icon to display an icon to represent the attachment. Here you are passing $attachment_id of the image set as your post thumbnail in the post and the size. The function in turn returns an array containing url, width and height, url being the first one, so using $image[0] will return the url of the image, which is fine.
If the image is still not being displayed, you need to confirm whether you have attached image as post thumbnail in your post and that the $images variable returns true on if clause.
Coming across a massive pain, is they a way I can for example say if has youtubeurl else show vimeourl?
Here is my coding
<?php $youtube_vimeo_player = get_post_meta($post->ID,'_youtube_vimeo_player',TRUE); ?>
<?php $info = $video->info("'".$youtube_vimeo_player['youtubeurl']."'"); ?>
<div class="content">
<div>
<a href="<?php echo get_permalink(); ?>" title="<?php echo $info['title']; ?>">
<img src="<?php echo $info['thumb_large']; ?><?php echo wp_get_attachment_url( $attachment->ID , false ); ?>" alt="<?php echo $info['title']; ?><?php echo $info['title']; ?>" class="thumb"/>
</a>
</div>
</div>
<?php $info = $video->info("'".$youtube_vimeo_player['vimeourl']."'"); ?>
<div class="content">
<div>
<a href="<?php echo get_permalink(); ?>" title="<?php echo $info['title']; ?>">
<img src="<?php echo $info['thumb_large']; ?><?php echo wp_get_attachment_url( $attachment->ID , false ); ?>" alt="<?php echo $info['title']; ?><?php echo $info['title']; ?>" class="thumb"/>
</a>
</div>
</div>
Any help would be more then great : )
Did you try
if ($youtube_video_url) {
//YouTube Stuff
}
else {
//Veoh stuff
}
??
If your asking how do an if statement inline style then this is how.
<? if (something == true) { ?>
<div>something</div>
<? } else { ?>
<div>something else</div>
<? } ?>
