map_canvas

Where would I place script below so I may get my Geocoder map canvas to work? Currently use https://wordpress.org/plugins/insert-php/ for the PHP which doesn’t work for headers nor footer.

<script type=”text/javascript”>

function initialize() {

var address = ‘<?=$loc?>’;
var geocoder = new google.maps.Geocoder();

geocoder.geocode( { ‘address’: address}, function(results, status) {
var location = results[0].geometry.location;
lat = location.lat();
lng = location.lng();

var myLatlng = new google.maps.LatLng(lat,lng);
var mapOptions = {
zoom: 19,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.HYBRID
}

var map = new google.maps.Map(document.getElementById(‘map_canvas’), mapOptions);

var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: “<?php echo $_POST[‘fulladdress’] ;?>”
});

});
}
//var myLatlng = new google.maps.LatLng(lat,lng);

</script>
