Question

I’m trying to activate a self-made wordpress plugin but am getting a T_Variable error on this line below.

type: "POST", url: "<?php$pluginDirectory = dirname(plugin_basename(__FILE__));?>/shoutbox.php", data: "action=insert&nick=" + nick + "&message=" + message,
                complete: function(data){

I’m having trouble figuring it out because I use the exact same php in another ajax call a few lines earlier but it doesn’t trigger an error on plugin activation. This code’s not triggering an error . Can anyone help?

$.ajax({
            type: "POST", url: "<?php$pluginDirectory = dirname(plugin_basename(__FILE__));?>/shoutbox.php", data: "action=update",
            complete: function(data){
                loading.fadeOut();
                messageList.html(data.responseText);
                messageList.fadeIn(2000);
            }
        });
    }

code that triggers an error

/*
Plugin Name: Shoutbox plugin
Plugin URI: http://www.blahblha.com/aboutmyplugin

function my_function {  ?>

$(document).ready(function(){
    //global vars
    var inputUser = $("#nick");
    var inputMessage = $("#message");
    var loading = $("#loading");
    var messageList = $(".content > ul");

//functions
function updateShoutbox(){
    //just for the fade effect
    messageList.hide();
    loading.fadeIn();
    //send the post to shoutbox.php
    $.ajax({
        type: "POST", url: "<?php echo $pluginDirectory = dirname(plugin_basename(__FILE__));?>/shoutbox.php", data: "action=update",
        complete: function(data){
            loading.fadeOut();
            messageList.html(data.responseText);
            messageList.fadeIn(2000);
        }
    });
}
//check if all fields are filled
function checkForm(){
    if(inputUser.attr("value") && inputMessage.attr("value"))
        return true;
    else
        return false;
}

//Load for the first time the shoutbox data
updateShoutbox();

//on submit event
$("#form").submit(function(){
    if(checkForm()){
        var nick = inputUser.attr("value");
        var message = inputMessage.attr("value");
        //we deactivate submit button while sending
        $("#send").attr({ disabled:true, value:"Sending..." });
        $("#send").blur();
        //send the post to shoutbox.php
        $.ajax({
            type: "POST", url: "<?php echo $pluginDirectory = dirname(plugin_basename(__FILE__));?>/shoutbox.php", data: "action=insert&nick=" + nick + "&message=" + message,
            complete: function(data){
                messageList.html(data.responseText);
                updateShoutbox();
                //reactivate the send button
                $("#send").attr({ disabled:false, value:"Shout it!" });
            }
         });
    }
    else alert("Please fill all fields!");
    //we prevent the refresh of the page after submitting the form
    return false;
});
});

<?php

}   //this bracket is creating the same problem....

add_action('wp_head', 'my_function');

All you need a a space after <?php and before $pluginDirectory
