    I am calling out shortcode several times on the page.
    Some Text
    [shortcode][/shortcode]
    More text
    [shortcode][/shortcode]
    I would like to count how many times the shortcode is called out before it renders as html and then display different output.
    Outputs are being loaded from settings page.
    not sure if I described the problem correctly, it a very unusual request

    this turned out to be fairll simple at the end. Just added indicator
    <?php
    $options = get_option( ‘cmby_settings’ );
    // Output Shortcode
    function cmby_list_widgets($atts, $content = null){
    static $i=0;
    $atts = shortcode_atts(array(
    ‘title’ => ‘Cambrick Yard Widgets’,
    ‘special’ => $ran
    ), $atts);
    global $options;
    $output = ‘<div class=”widgetcontainer”>’;
    $output .= ‘<div class=”widgetblock”>’;
    $output .= $options[“cmby_textarea_field_$i”].'<br/></div>’;
    $i++;
    return $output;

    }

    add_shortcode(‘cambrickyardwidgets’, ‘cmby_list_widgets’);

    Hi brveljkovic

    Does it matter if the shortcodes are in one post, or from multiple posts in a page?

    To count the shortcodes being output you can add a static counter to your shortcode
    http://php.net/manual/en/language.variables.scope.php#language.variables.scope.static

    Here’s an example shortcode

    
function my_content_shortcode( $atts, $content = null ) {
	static $count = 0;
	$count++;

	return '<span class="shortcode-count">My Shortcode ' . $count . '</span>';
}
add_shortcode( 'my_content', 'my_content_shortcode' );

    Hi keesiemeijer.

    I have a problem here. It seems WordPress will do shortcode twice times?

    If I call 3 times same shortcode on my post content. It will do the shortcode 6 times. The first 3 times like wordpress just doing the shortcode and will not print html, last 3 times will print html.

    When I using like your code on wordpress 4.8.2:

    function my_content_shortcode( $atts, $content = null ) {
	static $count = 0;
	$count++;

	return '<span class="shortcode-count">My Shortcode ' . $count . '</span>';
}
add_shortcode( 'my_content', 'my_content_shortcode' );

    The post content:

    No.1
[my_content][/my_content]
No.2
[my_content][/my_content]
No.3
[my_content][/my_content]

    And the post show

    No.1
My Shortcode 4
No.2
My Shortcode 5
No.3
My Shortcode 6

    Like the first N times to run the global, and then run N times to output. (N equal same shortcode was called)

    How can i solve it?

    Thank you.

    That might be because your theme or a plugin is doing stuff with the content before it’s displayed.

    I can only replicate your issue with something like this:

    
<?php
// Store the content
ob_start();
the_content();
$content = ob_get_clean();

// Display the content
the_content();
?>

    Can you replicate the problem using the default Twenty Seventeen theme with all other plugins deactivated?

    Emmm, when i using the default Twenty Seventeen theme, it was working fine.
    But my theme do not using any ob_*, when i let all of plugins deactivated, still have the issue.

    Any idea for this?

    Thanks a lot.

    I will track it on local later.

    Another way the counter could be incremented is by using do_shortcode() with your shortcodes in the content
    https://developer.wordpress.org/reference/functions/do_shortcode/

    Or by applying the filters of the content. Something like this.

    
$content = apply_filters('the_content', $content);

    Thank you.

    I will check it later.

    A lot of filters to apply for the content.

    Thank you, @keesiemeijer
    Found the problem, my header.php using like
    $content = apply_filters('the_content', $content);
    for html description meta tag.

    Now it’s ok.

    Thanks a lot.
