Currently I am working in One PHP Symfony Project Regarding the Performance Evaluation of an Employee.
So I need to know how we can get PHP session variable of an employee (Employee Role) Please see the php file ( $role = $_SESSION['empRole']; ) to an external js file.(js file also attached). I am using PHP Symfony framework.
Actually I need to check who is logged in to the website.if it is admin/core members / Hr.
I need to apply validation to some fileds only when the Coremembers login the website.
Here is the code section that I need to pass $role to External JS file(in pastebin)
public function executeIndex(sfWebRequest $request) {
if (isset($_SESSION['empId'])) {
$role = $_SESSION['empRole'];
if ($role == "admin") {
$empId = $this->getUser()->getAttribute('empId');
$team_members = GroupwareEmployeesPeer::getAllSubordinatesId($empId`enter code here`);
$nc = new Criteria();
$nc->add(PeD`enter code here`ates`enter code here`Peer::NAME, 'Dashboard');
$resultset = PeDatesPeer::doSelect($nc);
So Can you guys give me a solution regarding this, since I am stuck with this for a long time.
Please see thepastebin code for php and external js file.
https://pastebin.com/kbkLjSFa - PHP File.
https://pastebin.com/M60Rg64U - JS file
Yes you can get the php variable into the js file.
Method I:
Rename your .js file to .js.php and pass the php variable as a query string to this file where you link this file in your page.
So, if you have some test.js file, rename it to test.js.php and use it in your page like this
<script src="test.js.php?session_var=<?= $your_var_here;?>&any_var=<?= $any_php_var;?>"></script>
And in your js file, retrieve the values from query string parameters
So inside test.js.php, you can simply
var some_var = "<?= $_GET['session_var']";
var any_var = "<?= $_GET['any_var'];?>";
//rest of your logic goes here
Method II:
Use an AJAX request.
var some_var, another_var;
$.ajax({
url : '/url-which-returns-session-vars', //return the session data in json from this url
asnyc : false,
dataType : 'json',
success : function(res){
some_var = res.some_var;
another_var = res.another_var;
}
});
//rest of the logic goes here.
Both of these methods work. But I prefer the first method, since I don't have to write extra code.
Edit:
Suppose the response of the ajax call looks like this
{
some_var : 'value here',
another_var : 'another value here'
}
So res in the success function argument contains this response and since the response is a JSON you can access these values using the . notation.
Thus,
some_var = res.some_var;
another_var = res.another_var;
and since these variables are global variables, you can use them anywhere in your code in this file.
?> <script> var php_variable = '<?php $variable ?>'; </script> <?php
Global variable should be declared before external js file include . in js file access it using this variable name php_variable
After the above code . jquery external file should be included here
<script src="external.js" ></script>
external.js
consol.log(php_variable);
here is my sample code hope you can help me.
how can i pass a JavaScript variable to php variable?
<script>
var jsvar = "name";
</script>
<?php
$phpVar= jsVar;
?>
You can't. As others said million times, JavaScript is Client Side Language meanwhile PHP is Server Side. You can't manipulate Server Side language via Client Side Language. You should pass your JavaScript variable to Server with AJAX and do your operation.

I have a JavaScript file (extension .js, not .html) containing several JavaScript functions.
I want to call one of the PHP functions in a PHP file containing only several PHP functions from within one of the JavaScript functions.
Is that possible?
Would I need to "include" the .php file containing the PHP function in the .js file?
How would I do that? For example, say I had a file called myLib.php containing a function called myFunc that takes two parameters (param1 and param2). Then I have a .js file containing a function called myJsFunc. How would a call the myFunc (PHP) from within the myJsFunc (JavaScript function)? Wouldn't I need to include the PHP file somehow in the .js file?
7 years later update: This is terrible advice. Please don't do this.
If you just need to pass variables from PHP to the javascript, you can have a tag in the php/html file using the javascript to begin with.
<script type="text/javascript">
var phpVars = <?php echo json_encode($vars) ?>;
</script>
<script type="text/javascript" src="yourScriptThatUsesPHPVars.js"></script>
If you're trying to call functions, then you can do this like this
<script type="text/javascript" src="YourFunctions.js"></script>
<script type="text/javascript">
// assume each element of $arrayWithVars has already been json_encoded
functionOne(<?php echo implode(', ', $arrayWithVars); ?>);
functionTwo(<?php echo json_encode($moreVars) ?>, <?php echo json_encode($evenMoreVars) ?>);
</script>
AddType application/x-httpd-php .js
AddHandler x-httpd-php5 .js
<FilesMatch "\.(js|php)$">
SetHandler application/x-httpd-php
</FilesMatch>
Add the above code in .htaccess file and run php inside js files
DANGER: This will allow the client to potentially see the contents of your PHP files. Do not use this approach if your PHP contains any sensitive information (which it typically does).
If you MUST use PHP to generate your JavaScript files, then please use pure PHP to generate the entire JS file. You can do this by using a normal .PHP file in exactly the same way you would normally output html, the difference is setting the correct header using PHP's header function, so that the correct mime type is returned to the browser. The mime type for JS is typically "application/javascript"
PHP and JS are not compatible; you may not simply include a PHP function in JS. What you probably want to do is to issue an AJAX Request from JavaScript and send a JSON response using PHP.
A slightly modified version based on Blorgbeard one, for easily referenceable associative php arrays to javascript object literals:
PHP File (*.php)
First define an array with the values to be used into javascript files:
<?php
$phpToJsVars = [
'value1' => 'foo1',
'value2' => 'foo2'
];
?>
Now write the php array values into a javascript object literal:
<script type="text/javascript">
var phpVars = {
<?php
foreach ($phpToJsVars as $key => $value) {
echo ' ' . $key . ': ' . '"' . $value . '",' . "\n";
}
?>
};
</script>
Javascript file (*.js)
Now we can access the javscript object literal from any other .js file with the notation:
phpVars["value1"]
phpVars["value2"]
This is somewhat tricky since PHP gets evaluated server-side and javascript gets evaluated client side.
I would call your PHP file using an AJAX call from inside javascript and then use JS to insert the returned HTML somewhere on your page.
Actually the best way to accomplish this is to write the javascript in a .php and use jquery in a separate file to use the Jquery get script file or jquery load use php include function in the doc where the javascript will live. Essentially this is how it will look.
Dynamic Javascript File in a .php file extension - Contains a mixture of php variables pre processed by the server and the javascript that needs these variables in scripts.
Static Js File - Using http://api.jquery.com/jquery.getscript/ or http://api.jquery.com/load/
In the main html page call the static file as a regular js file. Calling the static js file will force load the dynamic data from the server.
some file.php 1:
<?php
$somevar = "Some Dynamic Data";
?>
$('input').val(<?php echo $somevar?>);
or simply echo the script such as
echo "$('input').val(".$somevar.");";
File 2:somejsfile.js:
$("#result").load( "file.php" );
File 3 myhtml.html:
<script src="somejsfile.js"></script>
I believe this answer the question for many people looking to mix php and javascript. It would be nice to have that data process in the background then have the user have delays waiting for data. You could also bypass the second file and simply use php's include on the main html page, you would just have your javascript exposed on the main page. For performance that is up to you and how you want to handle all of that.
Instead of messing with generic php-handlers do a 1-file exception using a rewrite:
Rename the .js-file to .php and rewrite the request to make it responde to a .js request. If the file is served by apache; add in .htaccess:
RewriteEngine on
RewriteRule myjsfile\.js myjsfile.php [L]
Secondly make the .php-file pretend to be a js-file. Inside the php-file start the file with:
<?php header('Content-Type: application/javascript'); ?>
Et voilà, you can now use php-tags in your ".js"-file.
You can't include server side PHP in your client side javascript, you will have to port it over to javascript. If you wish, you can use php.js, which ports all PHP functions over to javascript. You can also create a new php file that returns the results of calling your PHP function, and then call that file using AJAX to get the results.
Because the Javascript executes in the browser, on the client side, and PHP on the server side, what you need is AJAX - in essence, your script makes an HTTP request to a PHP script, passing any required parameters. The script calls your function, and outputs the result, which ultimately gets picked up by the Ajax call. Generally, you don't do this synchronously (waiting for the result) - the 'A' in AJAX stands for asynchronous!
You can make a double resolution of file:
"filename.php.js" in this way.
PHP generates JS in this file.
I got all parameters from DB.
This worked for me on xampp.
There is not any safe way to include php file into js.
One thing you can do as define your php file data as javascript global variable in php file. for example i have three variable which i want to use as js.
abc.php
<?php
$abc = "Abc";
$number = 052;
$mydata = array("val1","val2","val3");
?>
<script type="text/javascript">
var abc = '<?php echo $abc?>';
var number = '<?php echo $number ?>';
var mydata = <?php echo json_encode($mydata); ?>;
</script>
After use it directly in your js file wherever you want to use.
abc.js
function test(){
alert('Print php variable : '+ abc +', '+number);
}
function printArrVar(){
alert('print php array variable : '+ JSON.stringify(mydata));
}
Beside If you have any critical data which you don't want to show publicly then you can encrypt data with js. and also get original value of it's from js so no one can get it's original value. if they show into publicly.
this is the standard way you can call php script data into js file without including js into php code or php script into js.
I use DHTMLX. I want to use the ajax component get the data from php, the php will create the xml. How to get this xml data into javascript.
enter code here
dhtmlxAjax.get("php/getUsername.php", function(r){
r = r.xmlDoc.responseXML; // will give you DOM object
//console.log(r.firstChild.tagName);
alert(r.firstChild.tagName("param1"));
});
thank you
Just use the php echo function to echo the php variable into a java script variable.
eg. If you have a php variable called $XMLData you would do the following
var XMLdata = <?php echo $XMLData; ?>
Then on page load your php variable becomes a javascript variable and can be used. from anywhere in javascript provided that the variable is within its scope.
I have been reading how to pass variables from a php webpage to a separate javascript file, but am not having any luck.
Please don't mark this as duplicate, as I know there are a ton of things out there telling the ways to do this. I recognize those posts and am more just checking my syntax or seeing if there is anything unique about my specific situation that is causing those methods not to work.
So I have a PHP webpage where I POSTed some variables to:
DOCTYPE HTML
...
<?php
$id = $_POST["id"];
$name = $_POST["name"];
?>
...
HTML code with some usage of PHP variables
javascriptFunction()
end page
Then in a separate javascript file I have:
var markerlocation = '<?php echo $point; ?>';
function javascriptFunction () {
alert("markerlocation");
});
This seems really straight forward, but for whatever reason I can't get it. I also have tried with json encode.
I can delete this when done.
Sincere thanks for any help.
My way:
Declare a Array to store variable for passing variable to JavaScript
Encode the Array to JSON in php
Decode the JSON String from php and store as a JavaScript variable
PHP
<?php
//You may declare array for javascript
$jsVal = array(
'user_name' => 'Peter',
'email' => 'peter#gmail.com',
'marker_location' => '102,300'
);
?>
<script src="//ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script>var phpConfig = jQuery.parseJSON(<?=json_encode($jsVal)?>);</script>
Separated javascript file
alert(phpConfig.marker_location);
You can try it
You can point the script tag source to a .php file instead of a .js file, I think that's what you want. Works with image tags too ;)
Edit: some browsers may require the text/javascript mime header in order for it to work properly, but it's not hard with PHP I'll assume you already know how to do that.
On a side note: This option should probably only be used if you're planning on allowing the client to cache the javascript output. If you don't want the client to cache it, you need to set additional headers.
