Theme Convert PHP code to shortcode

admin••questions•阅读1

My theme uses this code which I am trying to convert to a shortcode so I can use on custom templates:<div class="

My theme uses this code which I am trying to convert to a shortcode so I can use on custom templates:

<div class="x-breadcrumb-wrap">
      <div class="x-container max width">

        <?php x_breadcrumbs(); ?>

      </div>
    </div>

I know I have to add a shortcode like this to my functions.php but can't figure out the syntax.

add_shortcode( 'mycrumbs', 'mytest_breadcrumbs' );

UPDATE:

For easy of use I only need to call the function x_breadcrumbs. My theme defines this function as:

function x_breadcrumbs() {

    if ( x_get_option( 'x_breadcrumb_display' ) ) {

      GLOBAL $post;

      $is_ltr         = ! is_rtl();
      $stack          = x_get_stack();
      $delimiter      = x_get_breadcrumb_delimiter();
      $home_text      = x_get_breadcrumb_home_text();
      $home_link      = home_url();
      $current_before = x_get_breadcrumb_current_before();
      $current_after  = x_get_breadcrumb_current_after();
      $page_title     = get_the_title();
      $blog_title     = get_the_title( get_option( 'page_for_posts', true ) );

      if ( ! is_404() ) {
        $post_parent = $post->post_parent;
      } else {
        $post_parent = '';
      }

      if ( X_WOOCOMMERCE_IS_ACTIVE ) {
        $shop_url   = x_get_shop_link();

  • Are there versions of your x_ functions that return values instead of echoing them? – Andy Macaulay-Brook Commented Oct 13, 2016 at 19:04
  • please see update.. – JoaMika Commented Oct 13, 2016 at 21:10
  • @JoannaMikalai your new code will have to be wrapped in ob_*() functions again, the reason for this is that both your codes, 1st and 2nd one produce output, but shortcodes must not produce output (see add_shortcode docs), so you have to capture output with ob_start and then save if with ob_get_clean() then return it, this is the only way you can do it. Or you will have to rewrite the function removing any echo or similar, and this seems doable for your function. One drawback, if the original function is improved by the theme author, will you keep track of that and modify your code? – Nabil Kadimi Commented Oct 14, 2016 at 6:40
  • And again, ob_* is safe stackoverflow/questions/4401949/… it becomes dangerous if not used currectly, as any code in any language. – Nabil Kadimi Commented Oct 14, 2016 at 6:42

Reset to default 1

This should do it, I used output buffering with ob_start() and ob_get_clean:

<?php

/**
 * Breadcrumbs based on theme's functions
 *
 * @author  Nabil Kadimi <[email protected]>
 * @link    http://wordpress.stackexchange/a/242547/17187
 */
add_action( 'init', function() {
    add_shortcode( 'mycrumbs', function() {

        /**
         * Start capturing output.
         */
        ob_start();

        ?>
        <div class="x-breadcrumb-wrap">
            <div class="x-container max width">
                <?php x_breadcrumbs(); ?>
                <?php if ( is_single() || x_is_portfolio_item() ) : ?>
                    <?php x_entry_navigation(); ?>
                <?php endif; ?>
            </div>
        </div>
        <?

        /**
         * Stop capturing output and return what was captured to WordPress.
         */
        return ob_get_clean();

    } ); // add_shortcode( 'mycrumbs', closure );
} ); // add_action( 'init', closure );

try this?

function mytest_breadcrumbs() {

$crumbs ='<div class="x-breadcrumb-wrap"><div class="x-container max width">';
$crumbs.=x_breadcrumbs();
if ( is_single() || x_is_portfolio_item() ) {
$crumbs.=x_entry_navigation();
}
$crumbs.='</div></div>';


    // Code
return $crumbs;
}
add_shortcode( 'mycrumbs', 'mytest_breadcrumbs' );

then call in page with [mycrumbs]
