VALUABLE HELP FOR WEBMASTERS
Caveat:
Is it possible to call PHP script using Javascript JS? It is a common
question of Webmasters implementing
complex coded web applications. The answer is NO*, however you can do it
using this trick!. The answer is still No, because Javascript is a piece
of code at the
browser, client-side application and PHP is at the server-side, different technologies,
different applications that cannot be
mixed,
however there is a possibility.
To
implement I'll use a click counter: The problem: can
be defined as “How
implement a counter of visitors of links with Onclick” or “how
count clicks using PHP and JS Onclick”. At that point,
I was customizing a Directory script and I wanted to count every visit of each
link using PHP and a MySQL database. Basically the database has the link’s
URL and a counter. Most of the javacript and PHP tutorials said you
can not do this, so… how count clicks using PHP?…
The solution: First I want that “on clicks” the
link open in a blank window:
<A HREF="PAGE_TO_VISIT.html]" target="_blank">PAG
TITLE</A>
Then the Java jscript’s
: OnClick is used to execute a PHP script embedded in regular PHP page:
<A HREF="PAGE_TO_VISIT.html" OnClick="parent.location='clickcounter.php?url=PAGE_TO_VISIT.html'" target="_blank">PAGE
TITLE</A>
-The Javascript
OnClick uses the parent.location to open clickcounter.php page in a parent
windows, so, the current page updates the counter in the same window
and the link will open in a separate window.
-I pass the parameter "URL"
to locate the MySQL specific record and increment the counter in 1: clickcounter.php?url=PAGE_TO_VISIT.html
The clickcounter.php code:
<?
// get the URL from the variable
$urlupdate = $_GET['url'];
// updates the counter
$bd = mysql_connect($mysql_hostname, $mysql_user, $mysql_password);
mysql_select_db($mysql_database, $bd);
$update = "UPDATE pages SET accesscounter = accesscounter + 1 WHERE url
= '$urlupdate'";
$result = mysql_query($update);
//return to previous screen
echo '<script type=""text/javascript"">history.go(-1);</script>';
?>
and Voilá, I had
executed PHP using Javascript JS OnClick.
See it in action with my
Live Demo, notice this my sandbox
so sometimes it does not work because I´m playing around. The first link
has the counter, complementary results are provided by my script
viXML, so you will not
see the counter on it.

| Looks like the author of this article doesn't know the diffrence between web page javascript and java. They are not the same. Not even close. |

This technique worked great the first time! - THANKS MUCH :smile:
I have no idea why someone would mention Java in a comment; near as I can make out, this has nothing to do with Java |

| That happened because I wrote Java instead of JS..ooops. I fixed later the article |
