Help with 2 issues

Hi Elliot, sorry about these probably stupid questions, I really tried with the docs and looking for help in the forums but really couldn’t solve this, so getting at you as last remedy since I know you must be very busy.

Anyway, here are my 2 issues:

1) Can’t get the size for images in repeater field

This is the code I’m using:

<?php 
$rows = get_field('main_courses');

if($rows)
{
foreach($rows as $row)
{
echo '<div class="dish">
<div class="dish-img"><img src="'.$row['main_course_image'].'" alt="" /></div>
<div class="dish-desc">
<h4>'.$row['main_course_name'].'</h4>
<div class="dish-desc-content">'.$row['main_course_description'].'
</div>
</div>
</div>
';
}
}
?>

The code works fine since it grabs all the info, but I want to get the thumbnail size (or even better, a custom size). I saw there are ways to select the sizes, like this:

$attachment_id = get_field('field_name');
$size = "full"; // (thumbnail, medium, large, full or custom size)
 
wp_get_attachment_image( $attachment_id, $size );

and others I have found, and I could make it work with no repeater fields, but couldn’t make it work with repeater, probably because I have no idea where to add those lines, or maybe because teh code I’m using for repeater field is no suitable for the images field or whatever. Either way, I hope you can help me with this.

2) Can’t make it show anything with the following code

<ul class="colorlist selectable">

<?php if( in_array( 'cblack', get_field('color_choices') ) ): ?>
<li><a id="black" class="switcher set1"><img src="<?php bloginfo('template_directory'); ?>/images/black.jpg" alt="" /></a> </li>
<?php endif; ?>
<?php if( in_array( 'cred', get_field('color_choices') ) ): ?>
<li><a id="red" class="switcher set1"><img src="<?php bloginfo('template_directory'); ?>/images/red.jpg" alt="" /></a> </li>
<?php endif; ?>
<?php if( in_array( 'green', get_field('color_choices') ) ): ?>
<li><a id="green" class="switcher set1"><img src="<?php bloginfo('template_directory'); ?>/images/green.jpg" alt="" /></a> </li>
<?php endif; ?>
<?php if( in_array( 'blue', get_field('color_choices') ) ): ?>
<li><a id="blue" class="switcher set1"><img src="<?php bloginfo('template_directory'); ?>/images/blue.jpg" alt="" /></a> </li>
<?php endif; ?>
<?php if( in_array( 'pink', get_field('color_choices') ) ): ?>
<li><a id="pink" class="switcher set1"><img src="<?php bloginfo('template_directory'); ?>/images/pink.jpg" alt="" /></a> </li>
<?php endif; ?>
<?php if( in_array( 'cgray', get_field('color_choices') ) ): ?>
<li><a id="gray" class="switcher set1"><img src="<?php bloginfo('template_directory'); ?>/images/grey.jpg" alt="" /></a> </li>
<?php endif; ?>
<?php if( in_array( 'corange', get_field('color_choices') ) ): ?>
<li><a id="orange" class="switcher set1"><img src="<?php bloginfo('template_directory'); ?>/images/orange.jpg" alt="" /></a> </li>
<?php endif; ?>
<?php if( in_array( 'clime', get_field('color_choices') ) ): ?>
<li><a id="lime" class="switcher set1"><img src="<?php bloginfo('template_directory'); ?>/images/lime.jpg" alt="" /></a> </li>
<?php endif; ?>
<?php if( in_array( 'csky', get_field('color_choices') ) ): ?>
<li><a id="sky" class="switcher set1"><img src="<?php bloginfo('template_directory'); ?>/images/sky.jpg" alt="" /></a> </li>
<?php endif; ?>

</ul>

I got a similar code from you some time ago and I modified it for another purpose, but this time isn’t showing anything, even though it looks similar (different field names of course). I did check the source just in case the images were missing, but it really didn’t output anything at all, so guess the code has some error, however I tried everything I coudl think of (which as you may imagine is pretty limited) to no avail

Anyway, thank you in advance and wish you a great and happy new year

Hi @cocobongo

#1
It looks like you have selected ‘Image URL’ as the return type setting for the image sub field. If you wish to load a custom size via the code posted, you must set the return type to ‘Image ID’. Please read the docs to better understand this.

#2
Please debug your variables to visually check if the data is correct and the logic will run. You can debug like so:

<?php 

echo '<pre>';
	print_r( get_field('color_choices') );
echo '</pre>';
die; ?>

Thanks
E
