jQuery and PHP in FOR loop for print_r

Question

I have the following:

for(var i = 0; i < triggerCount; i++) {

<?php $me = i; ?>

console.log(<?php echo $me; ?>);

jQuery('[data-key="field_5ee8665e2cd7f"] .acf-input .acf-actions [data-event="add-row"]').trigger('click');

jQuery('#ItineraryTab .acf-row input').eq(i).val("<?php print_r($array[$me]); ?>");
}

Which loops through a triggerCount variable and sets the input to each value in the array. However, if I use print_r($array[0]); then it shows uses this value from the array and places it into every iteration. How can I loop through this $array so similar to the count it places each value in order into each input in order?

You are mixing PHP and javascript. Where is the php $me defined? how about $iid? — Ibu

Have updated my question - but I am trying to get the $me in the printer array - so shouldn't it return 0 or 1 or 2 etc? — Paul VI

Just do var array = <?= json_encode($array) ?>; once and don't mix PHP with JS after it. — user1597430

You can not assign value of i (js) directly to $me (php). PHP executes on server side. Browser will execute javascript after he received all the content from the server meaning meaning php execution has finished already. — CarlosCarucce

Thanks @CarlosCarucce - so how would I need to rewrite this so it can also loop through a counter (for the print_r) — Paul VI

I think you should to use array_push() as:

for(var i = 0; i < triggerCount; i++) {

<?php
    $me = i;
    $array = []; 
    array_push($a, $me);
?>

console.log(<?php echo $me; ?>);

jQuery('[data-key="field_5ee8665e2cd7f"] .acf-input .acf-actions [data-event="add-row"]').trigger('click');

jQuery('#ItineraryTab .acf-row input').eq(i).val("<?php print_r($array[$me]); ?>");
}
