Hello. I need to retreive 3 RANDOM rows from a Repeater field with more than 3 rows, is that possible?
Thanks in advanced
Daniel
Hi @danielvierab
The following code should help you achieve that
<?php
// Get the repeater field
$repeater = get_field( 'repeater_field_name' );
// Get a random rows. Change the second parameter in array_rand() to how many rows you want.
$random_rows = array_rand( $repeater, 3 );
// Loop through the random rows if more than one is returned
if( is_array( $random_rows ) ){
foreach( $random_rows as $random_row ){
// Output data here. Replace sub field names.
echo 'Sub Field 1: ' . $repeater[$random_row]['sub_field_1'] . '<br/>';
echo 'Sub Field 2: ' . $repeater[$random_row]['sub_field_2'] . '<br/><br/>';
}
} else {
// Output data here. Replace sub field names.
echo 'Sub Field 1: ' . $repeater[$random_rows]['sub_field_1'] . '<br/>';
echo 'Sub Field 2: ' . $repeater[$random_rows]['sub_field_2'] . '<br/><br/>';
}
?>
Let me know if this helps.
Based on your resource page for displaying a random row, the code for doing this has changed to the following. I tried the code above and it didn’t work, but the code stated on the resource page does work to display a random row perfectly. My question now is how to mod it to display a random set of rows, not just one. Note, I tried adding that comma and a number that’s in your example, but it broke the whole output and displays nothing.
<?php
$rows = get_field('repeater_field_name' ); // get all the rows
$rand_row = $rows[ array_rand( $rows ) ]; // get a random row
$rand_row_image = $rand_row['sub_field_name' ]; // get the sub field value
// Note
// $first_row_image = 123 (image ID)
$image = wp_get_attachment_image_src( $rand_row_image, 'full' );
// url = $image[0];
// width = $image[1];
// height = $image[2];
?>
<img src="<?php echo $image[0]; ?>" />
