php sprintf not working as expected - php

Question

$actions = array(
'EDIT' => sprintf('Edit',
'abf_cm',
'edit_course',
$item['course_id'],
'thickbox edit-box',
'edit_'.$item['course_id']
),
'DELETE' => sprintf('Delete','course_management','do_process','delete',$item['course_id']),
);
In doing so, the edit part is not being displayed.Am i doing anything wrong.
I also tried using the placeholders
'EDIT' => sprintf('Edit',
'abf_cm',
'edit_course',
$item['course_id'],
'thickbox edit-box',
'edit_'.$item['course_id']
),
but still no results. I also noticed that when i remove the class and id attributes in the earlier version, then it works fine.
Can you please give me a satisfactory explanation of this and tell me where am i doing wrong.
EDIT:
Im using this inside Wordpress for creating custom table using WP_List_Table class
function column_course_name($item ) {
//Build row actions
$actions = array(
'EDIT' => sprintf('Edit',
'abf_cm',
'edit_course',
$item['course_id'],
'thickbox edit-box',
'edit_'.$item['course_id']
),
'DELETE' => sprintf('Delete','book_management','do_process','delete',$item['course_id']),
);
//Return the title contents
return sprintf('%1$s%3$s',
/*$1%s*/ strlen($item['course_name'])>0?$item['course_name']:'<span style="color:silver">(No Name)</span>',
/*$2%s*/ $item['course_id'],
/*$3%s*/ $this->row_actions($actions) //row_actions is a method in this class
);
}
update:
Well, its strange to mention but the code works when i use a single class( ie when i delete the space between the two classes for the tag) .
Any thoughts?

Dipesh, maybe you have errors in the code around this snippet.
Try to check your code in isolation. I copied your code to the separate .php script with little set-up and checked $actions array with print_r, like this:
edit_array.php
<?php
$item = array();
$item['course_id'] = 1;
$actions = array(
'EDIT' => sprintf('Edit',
'abf_cm',
'edit_course',
$item['course_id'],
'thickbox edit-box',
'edit_'.$item['course_id']
),
'DELETE' => sprintf('Delete','course_management','do_process','delete',$item['course_id']),
);
print_r($actions);
I ran this script from console and got the following results:
$ php edit_array.php
Array
(
[EDIT] => Edit
[DELETE] => Delete
)
Generated link for $actions['EDIT'] is HTML valid, so one can safely conclude that your code itself is working fine, and error lies somewhere else.
