Re: how to call a function when somebody click a link?

so i missed {}
is that the problem?

the browser will recognize it as a javascript and display it only by
the script tag.......
you donot think i shoud put the script tag?

errrrr
why the header() didnot work either?

You should write:
echo "window.location.href={$_SERVER['PHP_SELF']}";

But it won't work in your browser. Why do you want to put script tags
as action?

the code is like this
<form action="<?php dec_msgnum($cookie["usernum"]); echo "<script>";
echo "window.location.href=$_SERVER['PHP_SELF']"; echo '</script>';?>">
<input type="submit" value="忽略" /></form>

i also tried
<form action="<?php dec_msgnum($cookie["usernum"]);
header(default:$_SERVER['PHP_SELF'];';?>"> <input type="submit"
value="忽略" /></form>

it didnot work either :(

but this works perfectly well
<form action="<?php dec_msgnum($cookie["usernum"]); ';?>"> <input
type="submit" value="忽略" /></form>

do you think it is caused by some arguements missing?( may be it shoule
be $_SERVER['REQUEST_URI'] or $_SERVER['PHP_SELF']?xxxx=xxxxxx or
something)

the problem is that i donnot want some script.php
i want to redirect the users back on the page they were just on,with
calling a function in advance :)
you think the flag thing is the best way to do it?

i want to creat a link
when somebody click the link
the php script calls a function,then display itself :)

i have tried
<a href=<? funtion(); echo=$_server['php_self'] ?>text</a>
but it will call the function whether i click the link


then i tried this (using forms)
<form action="<?php function(); echo "<script>"; echo
"window.location.href=$_SERVER['PHP_SELF']"; echo '</script>';?>">
<input type="submit" value="text" /></form>
but it didnot work either.
my browser said there were parse errors,T_STRING expected or
something....:(


now i am thinking using a flag,say,$functioncall,
href=$_server[request_url]&functioncall=1
then if functioncall==1,call that function
but is it right?
is there some way simple to do that?


PHP works on a server, not in your browser, so it can't just call
function when you click a link. You have to send a request to the
server which will cause your script to call this function. Your last
example is good way to do it. So you have such link:
script.php?call=helloworld

and in your file script.php such code:

if ($_GET['call'] == 'helloworld') {
echo 'Hello world!';
}

Then after clicking the link your browser sends a request, PHP decides
what to do, then server sends you a appropriate response.
