how to use action

[raffael3d]

How can I use things like
<a href=\"$cgi;action=shownotify\">

how can I make usage of that action?
I defined a link using action. then in the target file I defined a function using that name. but seems not to work.
any tips? thanks.

Are you just trying to pass a variable in the URL that you can later grab with yoru function?

echo "<a href=\"page.php?action=showmodify\">";

Then to get the value of that action on page.php, you'd use $_GET['action']

OK...but what if one doesn't want a query string passed through the URL 😃

You could create a form with a hidden input field and simply use javascript in the link to submit the form....

....
<form name="theForm" method="post" action="somescript.php">
<input type="hidden" name="theFieldName" value="theFieldValue">
</form>

<a href="javascript:document.theForm.submit()">The Link</a>
....

...and voila! You can pass $_POST variables with a link.

Happy PHPing!

(PS. there should NO space between the words java and script in the link -- the forum automatically puts the space in there for security)
