Displaying slider on all pages

Child theme functions.php files doesn’t overwrite Parent theme functions.php file like it would happen with other files such assingle.php, page php and others.

You can’t also overwrite these script enqueues and you need to de-enqueue them first and then register them again.

Here is how you can get rid of default ones:

/**
 * Function to remove default slider scripts
 */
function sparkling_dequeue_script() {
    wp_dequeue_script( 'flexslider-customization' );
    wp_dequeue_script( 'flexslider-js' );
}
add_action( 'wp_print_scripts', 'sparkling_dequeue_script', 100 );

/**
 * Function to remove default slider CSS.
*/
function sparkling_dequeue_style() {
    wp_dequeue_style( 'flexslider-css' );
}
add_action( 'wp_print_styles', 'sparkling_dequeue_style', 100 );

Now you can enqueue these scripts without conditional formatting that makes sure that these scripts are loaded on the front page.

Also you will have to copy/paste slider function from Parent theme extras.php and remove conditional formation from that one as well. But that’s the simplest part here.

Thanks so much. I still can’t get this to work. Could there be an error in my original code to load the scrips on all the pages?

This is the code I’m using now:

<?php

/**
 * Function to remove default slider scripts
 */
function sparkling_dequeue_script() {
    wp_dequeue_script( 'flexslider-customization' );
    wp_dequeue_script( 'flexslider-js' );
}
add_action( 'wp_print_scripts', 'sparkling_dequeue_script', 100 

);

/**
 * Function to remove default slider CSS.
*/
function sparkling_dequeue_style() {
    wp_dequeue_style( 'flexslider-css' );
}
add_action( 'wp_print_styles', 'sparkling_dequeue_style', 100 );

// Add slider CSS only if is front page ans slider is enabled

if( ( of_get_option('sparkling_slider_checkbox') == 1 ) { 

wp_enqueue_style( 'flexslider-css', get_template_directory_uri

().'/inc/css/flexslider.css' );
  }

// Add slider JS only if is front page ans slider is enabled

if( ( of_get_option('sparkling_slider_checkbox') == 1 ) 

wp_enqueue_script( 'flexslider-js', get_template_directory_uri() 

. '/inc/js/flexslider.min.js', array('jquery'), '20140222', true 

);
	}

// Flexslider customization
  if( ( of_get_option

('sparkling_slider_checkbox') == 1 ) {
    wp_enqueue_script( 

'flexslider-customization', get_template_directory_uri() . 

'/inc/js/flexslider-custom.js', array('jquery', 'flexslider-js'), 

'20140716', true );
  }

/**

* Featured image slider, displayed on front page for static page 

and blog

*/

function sparkling_featured_slider() {
  if ( of_get_option( 

'sparkling_slider_checkbox' ) == 1 ) {    echo '<div 

class="flexslider">';
      echo '<ul class="slides">';

$count = of_get_option( 'sparkling_slide_number' );

$slidecat =of_get_option( 'sparkling_slide_categories' );

$query = new WP_Query( array( 'cat' =>$slidecat,'posts_per_page' 

=>$count ) );
        if ($query->have_posts()) :
          while 

($query->have_posts()) : $query->the_post();

          echo 

'<li>';
            if ( (function_exists( 'has_post_thumbnail' )) 

&& ( has_post_thumbnail() ) ) :
              echo 

get_the_post_thumbnail();
            endif;

              echo 

'<div class="flex-caption">';
                echo '<a href="'. 

get_permalink() .'">';
                  if ( get_the_title() != 

'' ) echo '<h2 class="entry-title">'. get_the_title().'</h2>';

              if ( get_the_excerpt() != '' ) echo '<div 

class="excerpt">' . get_the_excerpt() .'</div>';

echo '</a>';
              echo '</div>';

              endwhile;

         endif;

          echo '</li>';
      echo '</ul>';
    echo 

' </div>';
  }
}

I get the error: Parse error: syntax error, unexpected ‘{‘ in /[…]/wp-content/themes/sparkling-child/functions.php on line 22
