why not just pass in a variable to the php page then check if the var is there. If its there then run your function.

How would I do that?

I would like to know how to call a php function using javascript. I've done some googling and found that I need to use ajax. I read some tutorials and don't understand how to use ajax.

All I want to do is execute a php function, which writes to a txt file, from the execution of a javascript function. I don't care if the webpage refreshes or not; I'll just make the javascript function refresh the page.

Something like this:

<?php include 'banusers.php'; ?>
<script>
function banUser()
{
<?php writeIPToFile(); ?>
alert("You have been banned!");
window.location.reload();
}
</script>

<p>Click <a href="javascript:banUser();">HERE</a> to ban yourself!</p>

Would someone be kind enought to write an example for me?

I have this html code in a .php document:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>


<?php

//Logs client's IP
logIP();
//List of and invokes banned IPs
bannedIPs();
?>


<title><?php print "Your IP address is ". $_SERVER['REMOTE_ADDR'];?></title>
<link rel="stylesheet" href="http://code.jquery.com/ui/1.10.1/themes/base/jquery-ui.css" />

<script>
function banUser()
{
<?php addIPToBannedList(); ?>
alert("You have been banned!");
window.location.reload();
}
</script>


<script>
$(function() {
$( "#dragable" ).draggable();
});
</script>
<script type="text/javascript">

  (function() {
    var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
    ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
    var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);
	  })();

</script>

I have a link (line 59) that calls a JS function banUser(). It will do what I want to when I click the link, but the PHP code (line 26) gets excecuted on page load. I only want it executed when I click the link. How would I do that.

Edit: Added line numbers

I have a .txt document named bannedIPS.txt that has this in it:

12.326.25.3
192.168.1.1
207.236.2.32
10.218.24.5

and then my php script has this

//Gets user's IP
$ipaddress = $_SERVER['REMOTE_ADDR'];	

//List of IPs to block
$fh = fopen('UserIP/bannedIPS.txt','a+');
$ipBlockList = array();
$countWhileLoop = 0;
while($line = fgets($fh))
{
	$ipBlockList[$countWhileLoop] = $line;
	$countWhileLoop++;
}

fclose($fh);

//Determine if user IP is on the list
for($i=0; $i<=$countWhileLoop-1; $i++)
{ 

//Debug for seeing what $ipBlockList[$i] is
echo $ipBlockList[$i]."<br/>";

	if($ipaddress==$ipBlockList[$i])
	{
		echo "banned";
		exit;
	}
}

My IP address is 207.236.2.32 so it should display:

12.326.25.3
192.168.1.1
207.236.2.32

banned

but it displays:

12.326.25.3
192.168.1.1
207.236.2.32
10.218.24.5

so, the if statement isn't getting triggered. Why is that?

I'v tried:

if($ipaddress=="207.236.2.32")
	{
		echo "banned";
		exit;
	}

and then it works, but if it's the variable, it doesn't.

PS. I just started learning PHP today from W3Schools and Google.
