AJAX help wanted - John_Betong - 07-18-2017
I have managed to get an CI4 AJAX Dynamic Search routine working but it was an 'Orrible Kludge.
I had a tremendous amount of problems in trying to call this dbSearchResults.php file using the following JavaScript:
Code:
<script type="text/javascript">
function showResult(str)
{
...
...
...
xmlhttp.open("GET","dbSearchResults.php?q="+str,true);
xmlhttp.send();
}// endfunc ShowResults
</script>My knowledge of JavaScript is very basic and no solved or other solutions were found.
I would be very grateful for a link to a tutorial. If none are available then I would like to know the correct method to call and use a PHP file with AJAX.

First, load jQuery in the head section of your view.
Then, before the </body> closing tag, have this piece of code:
Code:
<script>
$(document).ready(function(){
var url = "<?= site_url();?>controller/method";
$.get( url, { p1: val1, p2 : val2 })
.done(function(data) {
//handle the returned data here
});
});
</script>In the controller, use $this->input->get('p1') to read the value of p1.
Let the controller method echo the data that you need back in the view.

Many thanks for the suggestion.
The following day I tried the AJAX call again and it worked for some weird reason! The previous day I had checked the filename and path, also tried renaming the file and using a different path, checked log files, file permissions, htaccess file, etc, etc, etc and all to no avail.

I have had that happen before, I reboot my computer system and then everything is fine.

LOL.
For a whole day I had a https error message implying my domain name was not secure. Today it just suddenly disappeared. WTF?
I sometimes wonder what my host is actually doing at times. Just cannot be bothered to change but perhaps I should.
