Run PHP code when user clicks link and pass variables
Question by user1323294
I need to run a PHP code from external server when user clicks a link. Link can’t lead directly to PHP file so I guess I need to use AJAX/jQuery to run the PHP? But how can I do it and how can I pass a variable to the link?
Something like this?
<a href="runcode.html?id=' + ID + '"> and then runcode.html will have an AJAX/jQuery code that will send that variable to PHP?

use something like this in you page with link
Some text
in the same page put this somewhere on top
<script language='javascript'>
$(function(){
$('.myClass').click(function(){
var data1 = 'someString';
var data2 = 5;//some integer
var data3 = "<?php echo $somephpVariable?>";
$.ajax({
url : "phpfile.php (where you want to pass datas or run some php code)",
data: "d1="+data1+"&d2="+data2+"&d3="+data3,
type : "post",//can be get or post
success: function(){
alert('success');//do something
}
});
return false;
});
});
</script>
on the url mentioned in url: in ajax submission
you can fetch those datas passed
for examlple
<?php
$data1 =$_POST['d1'];
$data2 =$_POST['d2'];
$data3 =$_POST['d3'];
//now you can perform actions as you wish
?>
hope that helps

You can do this with an ajax request too. The basic idea is:
- Send ajax request to runcode.html
- Configure another AJAX to trigger from that page
Considering, this as the markup
<a id="link" href="runcode.html'">Test</a>
JS
$("#link").on("click", function() {
$.get("runcode.html", { "id" : ID }, function(data) {
//on success
});
return false; //stop the navigation
});
