I will get right into it. I have an html page with a select form element tag named "location" and I coded a button to be able to add another select tag form field in case users need to indicate multiple different locations when submitting the form. My problem is I cannot seem to add an additional select form field with a different name=""
ideally I would like name="location0"
and when user clicks again to add another select form field it should be name="location1"
and so on...
I tried the push() function with this code:
<button onclick="add_fields()">Try it</button>
<p id="demo"></p>
<script>
var location= ["location"];
document.getElementById("invoice").innerHTML = location;
function add_fields() {
location.push("+")
document.getElementById("invoice").innerHTML = location;
}
</script>
but that did not work either. My implementation of this code is the problem I'm sure.
I provided my code in a js fiddle, the script is included in the html section, only worked in the html section (weird), any help is appreciated, thx.
Put "location[]" as the selects name and then when you receive the data via $_POST, that will be an array with the distinct values.
If you put something like this, you will see that:
<?php
if ($_SERVER['REQUEST_METHOD']==='POST') {
echo '<pre>';
print_r($_POST);
echo '</pre>';
//$locationArray=$_POST['location'];
}
?>
$_POST['location'] will be an array with the distinct values in the distincts positions
