My question is an extension of Dynamically populate a select field’s choices from the options page, referenced here (example 2).
On the options page we have a repeater field that collects a title, image, and link. Using the tutorial from the link above, we are able to pull in the title as choices in our checkbox. Once a user selects the options that he/she wants, we’d like to publish this content (image/title/link) that is stored on the options page, but obviously only from the subfields that were selected in the checkbox from the page editor.
I am having a hard time wrapping my head around this. Any help is greatly appreciated.
Hi @jrstaatsiii
All you will need to do is loop through all the rows from the options page repeater, and look for a match in the $title with that of which was selected on the post.
Something like this should work:
<?php
// vars
$title = get_field('select_field');
$image = false;
$link = false;
// find matching row
if( have_rows('repeater_field', 'option') )
{
while( have_rows('repeater_field', 'option' )
{
the_row();
if( get_sub_field('title') == $title )
{
$image = get_sub_field('image');
$link = get_sub_field('link');
}
}
}
// echo
echo '<img src="' . $image . '" />'
// etc...
?>
Hey Elliot, thanks for this push. Since I am using a checkbox which will pass an array instead of a single value, i used this:
// vars
$includedCrossSells = get_field('ssm_cross_sells_list', $id);
$crossSellTitle = get_sub_field('ssm_cross_sell_title', 'option');
// find matching row
if ( have_rows('ssm_cross_sells', 'option') ) {
while ( have_rows('ssm_cross_sells', 'option' ) ) {
the_row();
if ( in_array( (get_sub_field('ssm_cross_sell_title', 'option')), $includedCrossSells ) ) {
echo '<a href="' . get_sub_field('ssm_cross_sell_link', 'option') . '"><img src="' . get_sub_field('ssm_cross_sell_image', 'option') . '"</></a>';
echo '<p><a href="' . get_sub_field('ssm_cross_sell_link', 'option') . '">' . get_sub_field('ssm_cross_sell_title', 'option') . '</a></p>';
}
}
}
This works, but what is interesting is that when i pass $crossSellTitle as a variable which takes get_sub_field('ssm_cross_sell_title', 'option'); as a value, instead of using the full get_sub_field('ssm_cross_sell_title', 'option'); it doesn’t work. Can you spot why that is?
Thank you so much
Hi @jrstaatsiii
Your code:
$crossSellTitle = get_sub_field('ssm_cross_sell_title', 'option');
Is OUTSIDE of the have_rows loop. Therefore, ACF does not know which row of data you want to get the sub field value from! The sub field functions MUST be used WITHIN a has_field of have_rows loop.
Does that explain it?
#facepalm, of course. Thanks
