I was trying to pass a Javascript variable to PHP through POST xmlhttprequest but even a text literal is not working.
I checked the answered question /questions/20494437/passing-a-javascript-variable-to-php-with-xmlhttprequest but it did not work in my case. Below is my code
HTML/Script
<!DOCTYPE html> <html lang="en">
<button type="button" id="saveButton">Save Button</button>
<script> document.getElementById('saveButton').addEventListener('click', function() {
var inst_a = new XMLHttpRequest(); inst_a.open("POST", "check_name-indev02.php");
inst_a.send("inputname=dummy");
inst_a.onreadystatechange = function() {
if (inst_a.readyState == 4 && inst_a.status == 200)
{console.log(inst_a.responseText);}
}
});
PHP
<?php if (isset($_POST['inputname']))
{echo "set";} else {echo "not set";} ?>
I am not sure what I am doing wrong. The console always returns “not set” which means the constant “dummy” never reached the PHP. The actual page does a lot of other things including Jquery calls but only this part isn’t working. So I am including only the identified issue.
