I am trying to learn php and js. Here I am trying to put a value in php varible from javascript alert message input box but failed.
here what I have done so far,


Code: Select all

// <?PHP and other variable is here....
$number='number'; 

<script>
			function number{
				
				if (fail == "") {
					number = prompt('Please enter Phone Number')
					if (number == "" || number == null) { 
						alert(' You have not specified the Phone Number. Please try again.'); 
						
						return false;
					}
					else {
						
						document.getElementById("number").value;
						
						return true;
					}
				}
				else { alert(fail); return false; }
			}
		</script>
So, actually how I can store the value from js alert to php varible? help me. Thanks for your valuable time and opinion.

As PHP scripts only run when triggered, you have to make a request to your script's URL with the parameter in the URL or via POST / form. Or you take AJAX.
