Variables in Javascript URL

The problem you are probably having is that you are attempting to assign values from PHP variables to a JavaScript variable. JavaScript cannot retrieve PHP variables directly from the server. We are talking about both server-side and client-side scripting here. PHP operates on the server and JavaScript operates on the local machine.

Based on the URL example you provided, you are using a _GET method to submit form data to the next page using PHP.

What you will need to do is embed a PHP script within your JavaScript to dynamically generate the values needed for the JavaScript to work. See example below:

<?php
    $year = "2012";
    $month = "11";
    $day = "01";
    $area =  "12";
?>
...
<script language="javascript" type="text/javascript">
    var year = "<?php echo $year  ?>.";
    var month = "<?php echo $month ?>";
    var day = "<?php echo $day ?>;
    var area = "<?php echo $area ?>;
    
    
</script>
...

Select all Open in new window

At this point you can use the variables generated by PHP within your JavaScript construct using the JavaScript variables. Notice the difference between the PHP variable and JavaScript syntax. PHP uses the $ symbol to denote a variable, but JavaScript does not require any prefix.

I may not have explained myself very well. I need to create the three variables, year, month and day based upon whichever day it happens to be. Something like this:

var month = currentTime.getMonth() + 1;
var day = currentTime.getDate();
var year = currentTime.getFullYear();

Those variables then need to populate into the URL. Once I have the URL created isn't it a smple onclick event?

I found this code which nicely opens a browser window. My though process is that there my be a way to pass the date variables into the URL:

var simmy = window.open("http://www.google.com", "simWindow","status=0,menuBar=0,location=0,toolBar=0,directories=0,resizable=0,scrollbars=0,height=620,width=980");

You can develop a JavaScript function that will dynamically insert the variables and variable names into a URL. Example follows:

var url = "http://www.google.com?year="+year+"&month="+month+"&day="+day+"&area="+area;

The final markup would look something like this:

<script type="text/javascript">
var month = "12";
var day = "12";
var year = "2012";
var area = "02";	
var url = "http://www.google.com?year="+year+"&month="+month+"&day="+day+"&area="+area;

document.write("<a href="+url+">this link");
</script>

Select all Open in new window

Does this help you move in the right direction?

Just in case you want to use PHP to generate your variable data, you can use

<?php
$sysdate = date("d,m,Y");
?>

Select all Open in new window

This will return a variable value of DDMMYYYY format and it can be altered to include special characters in the return value.

This has worked:

var currentTime = new Date();
var month = currentTime.getMonth() + 1;
if(month<10){month='0'+month};
var day = currentTime.getDate("dd");
if(day<10){day='0'+day};

var year = currentTime.getFullYear();
var area = "02";


var simmy = window.open("http:"+"/"+"/"+"10.10.10.10"+"/"+"mrbs"+"/"+"web"+"/"+"day.php"+"%3F"+"year="+year+"%26"+"month="+month+"%26" +"day="+day+"%26"+"area="+area, "simWindow","status=0,menuBar=0,location=0,toolBar=0,directories=0,resizable=0,scrollbars=0,height=620,width=980");

Thanks, you steered me in the right direction.
