How do I execute a script based on a change to the total count of records in a mysql table. div1
echoes the amount of records in a table just fine. Using the .load ajax request, the div is constantly refreshed every 0,5 second so it'll always know how many records there are almost real-time.
<div class="div1">
<?php $row_cnt = mysqli_num_rows($result);
echo "table has $row_cnt records" ; ?>
</div>
<script>
function refreshdiv(){
$('.div1').load('backendform.php',function () {
$(this).unwrap();
});
}
refreshdiv();
setInterval(function(){
refreshdiv();
}, 500);
</script>
Here I'm trying to figure out how to call a JS function when the count has changed within the last minute (or second, doesn't matter). So if $row_cnt has for example changed from outputting 5 to 6, how do I trigger the execution for this statement?
<?php
//if record was added in last minute
if($row_cnt...)
echo '<script type="text/javascript">',
'notification();',
'</script>'
;?>
<script>
I suppose what also could work is if I could tell if a record has been added to the Mysql table within the last few seconds. Each record has a timestamp. But I don't even know if this can be done because I found no similar questions on SO.
