php - Using array_combine to show user input results -

i'm using array_combine show results of user choices.

this loop:

<?php if(get_field('sizes')) { ?> <?php while(the_repeater_field('sizes')) { ?> <?php echo the_sub_field('size'); ?> <input type="text" class="quantity" name="quantity[]" value="0"> <input type="hidden" class="productinput" name="product[]" value="<?php echo the_title(); ?> - <?php echo the_sub_field('size'); ?>"> <?php } ?> <?php } ?>

this how i'm outputting results

$quantities = array_combine($_post['product'], $_post['quantity']); foreach ($quantities $product => $quantity) { if ($quantity > 0) { $productresults = "$quantity x $product"; } } echo $productresults;

at moment outputs lastly input quantity , product name. e.g if alter 5 inputs shows 5th.

what missing show inputs changed?

use below code, problem outputing $productresults after foreach loop,and because of echoes lastly value assigned.

$productresults = ""; $quantities = array_combine($_post['product'], $_post['quantity']); foreach ($quantities $product => $quantity) { if ($quantity > 0) { $productresults .= "$quantity x $product "; } } echo $productresults;
