As far as I know the very first hook to jump in is wp_head
A quick and dirty workaround would be to add code into the theme’s header.php file.

well i am creating a plugin not a theme and so i suppose the only way i can do it create templates that get copied across to the theme’s folder.
But surely there must be a hook I can use to insert before the header/top of the page.
I just cant find anything elegant or clean that would work.
Any more suggestions?
You just need to enqueue your scripts before plugin does it. You can do it by setting priority to 0 for your hook. For example, do the following:
add_filter( ‘wp_enqueue_scripts’, ‘wpse8170_enqueue_my_scripts’, 0 );
// or if you enqueue your scripts on init action
// add_action( ‘init’, ‘wpse8170_enqueue_my_scripts’, 0 );
function wpse8170_enqueue_my_scripts() {
wp_enqueue_script( ‘myscript’, ‘http://path/to/my/script.js’, array( ‘jquery’ ) );
// my else scripts go here…
}

That was my first attempt but because the redirect is inserted at the end of the wp_head section it doesn’t work.
I has to come at the very top as well as the session variables that i am using.
So what i will probably end up doing is injecting pages/templates via the plugin into the theme which is not what i really wanted to do.
Why do you need to insert something via wp_head?
template_redirect runs before wp_head.
What is it exactly you want to do?
Yes agree with keesiemeijer
This action hook executes just before WordPress determines which template page to load.
It is a good hook to use if you need to do a redirect with full knowledge of the content that has been queried.
function my_page_template_redirect()
{
if( is_page( ‘goodies’ ) && ! is_user_logged_in() )
{
wp_redirect( home_url( ‘/signup/’ ) );
exit();
}
}
add_action( ‘template_redirect’, ‘my_page_template_redirect’ );

Ahhh ok sorry guys I miss read exactly what it does.
Appreciate you correcting me otherwise I would have completely missed it.
Which i have screwed something up in my code instead….well at least i can narrow down the issue better.
No problem 🙂
Good luck with the plugin

Thanks
ok so i am using this format and I get the feeling i am not using it correctly
In the plugin php file I have –
function init_web_header(){
include web_plugin_dir . ‘/pages/web-session.php’;
}
add_action(‘template_redirect’, ‘init_web_header’);
Is this the correct place/usage. Sorry for all the questions.
Is web-session.php a file inside your plugin folder?
What does the file do?
I don’t think template_redirect is the correct action for including files.
If you want to include that file before everything loads I would use the init action for that

the full path is wp-content/plugins/myplugin/pages/web-session.php’
At the moment i am just trying to get the following code to be accepted
session_start();
if (isset($_SESSION[‘auth_characterid’])) {
echo “Logged in. “.$_SESSION[‘auth_characterid’];
exit;
} else {
if(is_page(‘Login’)) {
echo “not logged in”;
// deal with SSO redirect
}
}
Where do you set $_SESSION['auth_characterid']?
Is there a reason you use sessions over WordPress functions like is_user_logged_in()

I am building a custom SSO login system which will go into a custom user area as i don’t wont to completely rewrite the wp-login system
and unfortunately add_action( ‘init’, ‘process_post’ ); doesnt appear to do anything at all, so should the add_action go into the plugin base file or somewhere else.
