使用jQuery .load将变量传递给PHP

I have a page ("main.php") which loads content from an external PHP file ("rpc.php"). Using the below syntax on main.php successfully pulls in content from rpc.php:

$("#portfolioContent").load("rpc.php?o="+day+"");

On rpc.php I have an if statement (part of a long switch function), as follows:

if ( $pagename == "home" ) {
break;
}

This break is not occuring because the variable has not been set. rpc.php is used by various parent pages so the variables need to be set on those. On a parent page I have tried using the following code to attempt to set the variable and pass it to rpc.php but to no avail:

$("#portfolioContent").load("rpc.php?o="+day+"$pagename="home"");

Can anybody point me in the right direction? Thank you.

It should be like this,

$("#portfolioContent").load("rpc.php?o="+day+"&pagename=home");

To access variables from the URL in PHP just do: $_GET['variablename']

For example, with the URL http://www.example.com?hello=hellWorld

echo $_GET['hello'];

would print helloWorld

Also, you use & to separate variables, not $

change this line

$("#portfolioContent").load("rpc.php?o="+day+"$pagename="home"");

to this

$("#portfolioContent").load("rpc.php?o="+day+"pagename="home");

then access the variable with $_GET['pagename']

Your syntax is wrong. Try this:

$("#portfolioContent").load("rpc.php?o="+day+"&pagename=home");

Notice i substituted the $ with a &

Cheers
