I'm pulling both the 'book_series' and 'series_link' from custom fields within Wordpress.
The link shows up correctly when a name and URL are included but it shows "Books Series:' on blank pages (that don't include links or series). How can I hide the content when left blank?
Here is what I have so far:
<?php if (('books_series') == true) : ?>
<div class="series"><b>Book Series: </b><?php the_field( 'books_series' ); ?></div>
<?php else: ?>
<div class="series" hidden></div>
<?php endif; ?>
Thank you.
Maybe,
if (('books_series') == true)
Should be:
if (the_field('books_series') == true)
This is what I came up with and it seems to work, although I'm not sure how functional it is overall - `
<?php if ($series_link) { ?>
<div class="series"><b>Book Series: </b><?php the_field( 'books_series' ); ?></div>
<?php } ?>`
Thank you everyone for your help and suggestions.

Can anyone please help me wrap the condition inside another condition in php.
I have this code #1 that I want to be inside code #2.
Here's code #1
<?php if( get_field('highlights') ): ?>
<div class="overview">
<h3>Quick Overview</h3>
<?php the_field('highlights'); ?>
</div>
<?php endif; ?>
Here's code #2
<?php if(strstr($_SERVER['HTTP_REFERER'],'www.example.com'))
{
echo '**CODE #1 should be placed here**';
}
?>
Sorry, I don't haev any knowledge in PHP.
Wrapping code 1 inside code 2
After several trial and error, here's what I have to make it work. Please correct me if there's something wrong or to improve.
<?php if (strstr($_SERVER['HTTP_REFERER'], 'www.google.com')){ ?>
<?php if( get_field('highlights') ):?>
<div class="overview">
<h3>Quick Overview</h3>
<?php the_field('highlights'); ?>
</div>
<?php endif; ?>
<?php } ?>
This should work in theory. Though I'm unsure what the highlights field is for.
<?php
if(strstr($_SERVER['HTTP_REFERER'],'www.example.com')){
if( get_field('highlights') ){ ?>
<div class="overview">
<h3>Quick Overview</h3>
<?php the_field('highlights'); ?>
</div>
<?php
}
}
?>
You may want to replace <?php the_field('highlights'); ?> with something like <?=highlight ?> and iterate through the highlights in a loop. That depends on the situation though.
Argh, this code is not pulling through my custom meta.
<?php
$my_meta = get_post_meta($post->ID,'_my_meta', true);
if (!empty($post_meta)) {
?>
<div class='client-testimonial'><?php echo $my_meta['testimonial']; ?></div>
<div class='client-name'><?php echo $my_meta['name']; ?></div>
<?php
}
?>
But the one below works, the only reason I am not using it is because it still shows the speach marks and dash when the fields are left empty in the admin panel
<?php
$my_meta = get_post_meta($post->ID,'_my_meta', true);
echo "<div class='client-testimonial'>". "'".$my_meta['testimonial']."'". "</div>";
echo "<div class='client-name'>". "-" .$my_meta['name']."</div>";
?>
Please help me on why the first code is not echoing the info. I am at the end of my tether!
You're checking if $post_meta is not empty, you don't have a variable named $post_meta
Change:
if (!empty($post_meta))
to
if (!empty($my_meta))
i think u have checked wrong variable.
<?php
$my_meta = get_post_meta($post->ID,'_my_meta', true);
if (isset($my_meta) && !empty($my_meta)) {
?>
<div class='client-testimonial'><?php echo $my_meta['testimonial']; ?></div>
<div class='client-name'><?php echo $my_meta['name']; ?></div>
<?php
}
?>
I have the following code:
<?php $buycheck = get_post_meta($post->ID, 'buy-link', true); ?>
<?php if ( $buycheck ) : ?>
<div class="section-title sidebar span5">
<h5>Get This Release</h5>
</div>
<?php else : ?>
<div class="section-title sidebar span5">
<h5>More Releases</h5>
</div>
<?php endif; ?>
Later in my code I want to be able to say that if buy-link does not exist - i.e. there is no data in that field - then do something, else do something different.
Not sure how to do this! Help appreciated!
(By the way, I posted this question to Wordpress Stack Exchange first. It was voted closed there because it apparently concerns PHP boolean logic more than Wordpress - https://wordpress.stackexchange.com/questions/60387/how-do-i-do-if-post-meta-does-not-exist#comment78412_60387)
<?php if($buycheck ==''){ /*stuff*/ } ?>
this will render $buycheck, and if it is empty == is equal to '' nothing.
You can set a global variable that you can check later to see if the buylink exists:
<?php
$buycheck = get_post_meta($post->ID, 'buy-link', true);
$GLOBALS['buy_link_exists'] = !empty($buycheck);
?>
<?php if ( $buycheck ) : ?>
<div class="section-title sidebar span5">
<h5>Get This Release</h5>
</div>
<?php else : ?>
<div class="section-title sidebar span5">
<h5>More Releases</h5>
</div>
<?php endif; ?>
Then later on in your code:
<?php if ($GLOBALS['buy_link_exists'])): ?>
it exists, do one thing
<?php else: ?>
it does not exist, do something else
<?php endif; ?>
If you need the actual value, you can set a global containing the return value from get_post_meta so you can use the actual value.
Basically, I need for the image at the bottom of the page with no text wrapped around it to be in the place of test post 4 (it's going to be a Google Adsense block but I am using images as a placeholder for now). I'm not sure how to do this, right now the code is the following:
<div class="google_ad_post">
<?php if ($count == 3) { ?>
<br /><img src="****" alt="post ad">
<?php } ?>
<?php $count++; ?>
</div>
Yet, the image is still at the bottom of the page. How can I fix this?
Here is the image:
I can't post pictures just yet so the URL to the image is http://i.imgur.com/7rw5B.jpg
I have to see your code to help you better with the Scripting Part, but something logical like this should work:
<?php
$count = 0;
foreach( $posts as $post ) : ?>
<?php if ($count == 3) { ?>
<div class="google_ad_post">
<img src="****" alt="post ad">
</div>
<?php } else { ?>
<div class="post" id="post-<?php the_ID(); ?>><div class="content"><?php the_content(); ?></div>
<?php } ?>
<?php $count++; ?>
<?php endforeach; ?>
I created an unordered list of custom fields and I wish to hide them if they are empty. For text custom fields I used the code:
<?php if (get_field('phone') != '') { ?>
<li><strong>Phone: </strong><?php the_field('phone'); ?></li>
<?php } ?>
However, I have a custom field which is for images, like this:
<li><strong>Logo: </strong><img src="<?php the_field('logo'); ?>"></img></li>
How can I hide the field if no image was uploaded (obviously, the above code won't work)?
Thanks in advance.
I think it should be
<?php if (get_field('logo') != ''): ?>
<li><strong>Logo: </strong><img src="<?php the_field('logo'); ?>"></img></li>
<?php endif; ?>
Assuming the_field('logo') will return a falsy value if there are no images
if (the_field('logo')) {
?>
<li><strong>Logo: </strong><img src="<?php the_field('logo'); ?>"></img></li>
<?php
}
<?php if( get_field('field_name') ): ?>
<p>My field value: <?php the_field('field_name'); ?></p>
