Included Javascript AND PHP

[AndieB]

Hi all,

 

I've got a Javascript code (in an external file) that has the function to validate values in a FORM. Now, I've created my webpage to support more than one language, this by creating a lang.php file where variables are set.

 

As an example eng.lang.php looks like this:

$langpack["title"] = "Welcome!";

 

and for another language, Swedish, the "almost" same file looks like this:

$langpack["title"] = "Välkommen!";

 

Based on the visitors selection of language, the relative language file is included.

 

My question now is:

 

Is it possible to put PHP variables in a Javascript, so that it is processed when the page is loaded and the PHP variables are replaced with values that Javascript can interpret?

 

In my current Javascript code for validating the FORM, is something is not according to my rules, an ALERT box appears, but the text is in English. I would like to be able to use my *.lang.php files variables together with Javascript, so the ALERT boxes displays the message in the language that the visitor has choosen.

 

Am I clear with what I want to achieve?

 

Thank you in advance!

 

Sincerely,

Andreas

i see your php vars are arrays. you could simply make php build a jsarray from your php array like so

/**
* Returns a jsArray in string format
* @param array $array
* @param string $name
* @return string
*/
function jsArray($array,$name){
$jsArray="var {$name} = new Array();\n";
foreach($array as $key=>$val){
	$jsArray.=(is_numeric($val))?"{$name}['{$key}']={$val};\n":"{$name}['{$key}']=\"{$val}\";\n";
}
return $jsArray;
}
$langpack=array();
$langpack["title"]="some tite";
$langpack["error"]="some error";
$langpack["someothercrap"]="someothercrap";

echo jsArray($langpack,"jsarray");//this will be a jsarray
