PHP Question

Override Plugin Function in WordPress

I have a Plugin installed on my WordPress site.

I'd like to override a function within the Plugin. Do I override this in my theme's

functions.php
and if so, how do I do this?

Here's the original function in my plugin:

/**
* sensei_start_course_form function.
*
* @access public
* @param mixed $course_id
* @return void
*/
function sensei_start_course_form( $course_id ) {

$prerequisite_complete = sensei_check_prerequisite_course( $course_id );

if ( $prerequisite_complete ) {
?><form method="POST" action="<?php echo esc_url( get_permalink() ); ?>">

<input type="hidden" name="<?php echo esc_attr( 'woothemes_sensei_start_course_noonce' ); ?>" id="<?php echo esc_attr( 'woothemes_sensei_start_course_noonce' ); ?>" value="<?php echo esc_attr( wp_create_nonce( 'woothemes_sensei_start_course_noonce' ) ); ?>" />

<span><input name="course_start" type="submit" class="course-start" value="<?php echo apply_filters( 'sensei_start_course_text', __( 'Start taking this Course', 'woothemes-sensei' ) ); ?>"/></span>

</form><?php
} // End If Statement
} // End sensei_start_course_form()

Answer

You can't really "override" a function. If a function is defined, you can't redefine or change it. Your best option is to create a copy of the plugin and change the function directly. Of course you will have to repeat this everytime the plugin is updated.

Give the plugin a different name to distinguish them in the plugin listing. Disable the original, enable your copy.
