I was wondering if this is at all possible:
I’d like a repeater loop that basically has some sort of count that says if row 1 has value then do this, if row 2 has a value do this and this.
Basically what I’m trying to achieve is if row 1 has a value display a full width column, but if there are 2 rows then display row 1 in a div then row 2 in another div etc etc.
So basically something like
if there is only 1 row present then:
<div class="full"> SUBFIELD 1</div>
If there are 2 row’s present then:
<div class="half"> Subfield 1</div>
<div class="half">Subfield 2</div>
If there are 3 row’s present then:
<div class="third"> Subfield 1</div>
<div class="third">Subfield 2</div>
<div class="third">Subfield 3</div>
I could do it simply with just some if has value, but all 3 fields would be present. Was wondering if its possible with the repeater?
Many thanks!
In your frontend, you’ll have to count number of elements in the repeater field array. So something like this:
<?php
// pre define the allowed columns
$allowed_classnames = array(
1 => 'full',
2 => 'half',
3 => 'third',
4 => 'fourth',
5 => 'fifth',
);
// get the count on the repeater field
// mabye use get_sub_field() instead of get_field() if it's nested
$number_of_cols = count( get_field( '<repeater>' ) );
// set a default classname
$classname_to_use = $allowed_classnames[1];
// check if the $number_of_cols exist in the predefined classnames
if ( array_key_exists( $number_of_cols , $allowed_classnames ) ) {
// set the classname to be used
$classname_to_use = $allowed_classnames[$number_of_cols];
}
while( has_sub_field( '<repeater>' ) ) : ?>
<div class="<?php echo esc_attr( $classname_to_use ); ?>">
<?php the_sub_field( '<repeater_content>' ); ?>
</div>
<?php endwhile; ?>
Please not that I just briefly tested it on a site I’m working on. You’ll have to replace the '<repeater_content>' and '<repeater>' with your actual field names.
You sir are a genius!
I knew i had to have a count in there somewhere just wasnt sure how to implement it – this is exactly what I was after 🙂
@neverything, thanks for your post. I used your example to make something for a project I’m working on, but all I needed to do was count number of field and apply different conditions. Here is my stripped down example below:
<?php
// get the count on the repeater field
// mabye use get_sub_field() instead of get_field() if it's nested
$count = count( get_sub_field( 'the_field' ) );
// begin $count conditions
if ( $count > 1 ) { ?>
// greater than 1
<?php the_field( 'great_than_1' ); ?>
<?php } else { ?>
// less than 1
<?php the_field( 'less_than_1' ); ?>
<?php } ?>

Cool @emaildano, thanks for sharing your solution.
Awesome! Just what I was looking for. Thanks all above 🙂
