Possible to randomize shortcode parameter?

Do you mean auto generating an ID between 120 and 130 in PHP?
You could use rand("120","130") for that..

Or the user has to set that ID?

Explain more on this ??

Thank you for responding ??

As I’m editing the page I can write [shortcode id = '123'] and it causes a modal popup with the “id” of ‘123’ to appear on the page. If I code [shortcode id = '128'] then instead of popup ‘123’ up comes ‘128’. What I would like to happen is that a random popup appears instead of just the same ‘123’ or ‘128’ popup over and over.

Putting [shortcode id = 'rand("120","130")'] doesn’t fly.

Can this only be done by editing the plugins code?

Putting [shortcode id = ‘rand(“120″,”130”)’] doesn’t fly.

No, that code can be implemented in the shortcode function.

What is the shortcode about? and can we have a look at the code used for it? e.g PHP function, plugin..

It doesn’t seem to work in my case anyway :/

The plug-in is easy popup announcement, the code for the shortcode is thus:

<?php

/*
 * Shortocode for single post / page
 */
function epa_setcookie_post() {
	$epa_expire = get_option( 'epa_expire' );
	$expire = time() + (float) $epa_expire;
	if(isset($_COOKIE['epa_popup'])):
	else:
		//$_COOKIE['epa_popup'] = 'active';
		setcookie('epa_popup', 'active', $expire);
	endif;
} 

function epa_shortcode_single( $atts ) {
	$atts = shortcode_atts( array(
 	      'id' => ''
      ), $atts );

	$default_popup = get_post($atts['id']);

	if(get_option('epa_enable') == 'no') :

		$epa_html .= '<div id="my_popup" class="well"><span class="my_popup_close"></span>';
		$epa_html .= $default_popup->post_content;
		$epa_html .= '</div>';

		if(!isset($_COOKIE['epa_popup'])) {
			return $epa_html;
		}

	endif;

}
add_shortcode( 'epapop', 'epa_shortcode_single' );

Can you check this:

<?php

/*
 * Shortocode for single post / page
 */
function epa_setcookie_post() {
	$epa_expire = get_option( 'epa_expire' );
	$expire = time() + (float) $epa_expire;
	if(isset($_COOKIE['epa_popup'])):
	else:
		//$_COOKIE['epa_popup'] = 'active';
		setcookie('epa_popup', 'active', $expire);
	endif;
} 

function epa_shortcode_single( $atts ) {
	$atts = shortcode_atts( array(
 	      'id' => ''
      ), $atts );

	//$default_popup = get_post($atts['id']);
	$default_popup = get_post(rand("120","130"));

	if(get_option('epa_enable') == 'no') :

		$epa_html .= '<div id="my_popup" class="well"><span class="my_popup_close"></span>';
		$epa_html .= $default_popup->post_content;
		$epa_html .= '</div>';

		if(!isset($_COOKIE['epa_popup'])) {
			return $epa_html;
		}

	endif;

}
add_shortcode( 'epapop', 'epa_shortcode_single' );

And don’t set any ID attribute for the shortcode..

?

Wooohooo!!!! You did it ?? If Apple hadn’t made such a mockery of the word genius I would call you one, in lieu, you are a virtuoso!

Hahahaha !

I am glad it worked for you. and thanks for the compliment!
