I\'m having problems finding the right hook to use for my plugin. I\'m trying to add a message to the top of each page by having my plugin add a function. What\'s the best h

    Creating custom hook is really easy in WordPress. in header.php (or anywhere you may need a hook) locate: 

    <body <?php body_class(); ?>>
<div id="body-container">

    and make it: 

    <body <?php body_class(); ?>>
<?php body_begin(); ?>
<div id="body-container">

    That's our hook, now let's make it work. In functions.php add:

    function body_begin() {
do_action('body_begin');
}

    Now hook is ready to use, simply add any actions you need in functions.php:

    function my_function() {
/* php code goes here */
}
add_action('body_begin', 'my_function');

    or JavaScript (tracking code etc - this is not the perfect way though, it is a better practice to load JavaScript from .js files, but it is definitely better than adding JavaScript directly to template files):

    function my_function() { ?>
<script>
<!-- JavaScript goes here --!>
</script>
<?php
}
add_action('body_begin', 'my_function');

    I searched the internet for answers to the same question but found nothing. I figured out away to to work around it. My plugin infinite Ad Pay is based on this method.

    You need two hooks wp_head and wp_footer hook

     

add_action( 'wp_head', 'my_buffer_holder_fxn');

function my_buffer_holder_fxn(){
ob_start()


}


function my_buffer_pour_out_fxn(){

$get_me_buffers  = ob_get_clean();

$pattern ='/<[bB][oO][dD][yY]\s[A-Za-z]{2,5}[A-Za-z0-9 "_=\-\.]+>|<body>/';
ob_start();
if(preg_match($pattern, $get_me_buffers, $get_me_buffers_return)){


$d_new_body_plus =$get_me_buffers_return[0]."<div class='my_below_body_code'> This is below the body text or image or anything you want </div>";

echo preg_replace($pattern, $d_new_body_plus, $get_me_buffers);

}
ob_flush();
}



}

add_action( 'wp_footer', 'my_buffer_pour_out_fxn');


// You can also use the method above to place anything in other sections of WordPress 
//No Javascript used

    In this scenario, what i do is: Use Jquery to append or prepend things:
