Ok, I found that fuzzy search is triggered by appending “~” to the query string, hence the fuzziness amount parameters needs to be set at minimum value of 2.
This is not a good approach because no common user will append ~ to his query string without anyone telling him to. I edited the code, adding ~ to every query string, so that fuzzy search is always triggered.
I’ve just started exploring ElasticSearch and I don’t know it well, so this is probably not the best way to arrange things, but at least it’s working.

I noticed the plugin uses ruflin/Elastica php client, so I downloaded the latest version of that library, then searches started giving results (I’m using version 1.5.1 of ElasticSearch server, so I think server and php client versions simply didn’t match).

Not everything is ok though, because fuzzy searching is not working at all. Have you got any suggestion?

I worked on this a lot of time ago, so I don’t remember that much. I think I gave up on Dynamic Cache Tag (the first option) because it didn’t work the way I needed, calling my functions ecc.
Speaking about the output buffer: the code is still quite simple. You can define your constant where you prefer, like this:

define( 'DYNAMIC_OUTPUT_BUFFER_TAG', 'Your placeholder' );

The dynamic cache is not the only option to keep part of your pages dynamic, anyway: if you have issues with that, you should try loading your content via ajax.

This is an example of usage for a woocommerce cart widget.
I use this code in functions.php:

if ( DYNAMIC_OUTPUT_BUFFER_TAG != '' ) {

  function dynamic_output_buffer_minicart( &$cachedata = 0 ) {
  	if ( defined( 'DYNAMIC_OB_TEXT' ) )
  		return str_replace( DYNAMIC_OUTPUT_BUFFER_TAG, DYNAMIC_OB_TEXT, $cachedata );

  	ob_start();
  	// call the sidebar function, do something dynamic
  	woocommerce_mini_cart();

  	$text = ob_get_contents();
  	ob_end_clean();

  	if ( $cachedata === 0 ) { // called directly from the theme so store the output
  		define( 'DYNAMIC_OB_TEXT', $text );
  	} else // called via the wpsc_cachedata filter. We only get here in cached pages in wp-cache-phase1.php
  		return str_replace( DYNAMIC_OUTPUT_BUFFER_TAG, $text, $cachedata );
  }

  function dynamic_output_buffer_init() {
  	add_action( 'wp_footer', 'dynamic_output_buffer_minicart' );
    //add_action( 'wp_footer', 'dynamic_output_buffer_sidebar' );
  }

  function dynamic_output_buffer_test_safety( $safety ) {
  	if ( defined( 'DYNAMIC_OB_TEXT' ) ) // this is set when you call dynamic_output_buffer_test() from the theme
  		return 1; // ready to replace tag with dynamic content.
  	else
  		return 0; // tag cannot be replaced.
  }  

  add_cacheaction( 'wpsc_cachedata', 'dynamic_output_buffer_minicart' );
  add_cacheaction( 'add_cacheaction', 'dynamic_output_buffer_init' );
  add_cacheaction( 'wpsc_cachedata_safety', 'dynamic_output_buffer_test_safety' );

}

And this code in my template page:

<?php
    if ( function_exists( 'dynamic_output_buffer_minicart' ) )
      dynamic_output_buffer_minicart();
    ?>Loading cart...

You should also enable late_init option in the WP Super Cache configuration.

Yes, the_title() has to be called from inside the loop, you’re right. I edited the code to make the function to be called this way, but it doesn’t work:I still get ‘Events’ as title.
The problem is that neither the wp_title() is working, so there must be something else I’m missing…

Hi Franky, thank you for your answer. It’s somehow more complicated: I tried replacing the custom function of my theme with the standard “the_title()” call, but nothing changes. The only other difference between my custom theme and a standard one is that the title block is written in the header.php file, instead of the page.php.
Also, I cannot see the right title in the browser tab(<title> tag), even if it’s called the wp_title() function.

Ok, that didn’t work because there was no call to dynamic_output_buffer_test function in my template.

So, the correct code should be

function dynamic_output_buffer_test( &$cachedata = 0 ) {
	if ( defined( 'DYNAMIC_OB_TEXT' ) )
		return str_replace( DYNAMIC_OUTPUT_BUFFER_TAG, DYNAMIC_OB_TEXT, $cachedata );

	ob_start();
	// call the sidebar function, do something dynamic
	strtest();
	$text = ob_get_contents();
	ob_end_clean();

	if ( $cachedata === 0 ) { // called directly from the theme so store the output
		define( 'DYNAMIC_OB_TEXT', $text );
	} else // called via the wpsc_cachedata filter. We only get here in cached pages in wp-cache-phase1.php
		return str_replace( DYNAMIC_OUTPUT_BUFFER_TAG, $text, $cachedata );
}
function dynamic_output_buffer_init() {
	add_action( 'wp_footer', 'dynamic_output_buffer_test' );
}
function dynamic_output_buffer_test_safety( $safety ) {
	if ( defined( 'DYNAMIC_OB_TEXT' ) ) // this is set when you call dynamic_output_buffer_test() from the theme
		return 1; // ready to replace tag with dynamic content.
	else
		return 0; // tag cannot be replaced.
}
function strtest() {
  echo "hello";
}

add_cacheaction( 'wpsc_cachedata', 'dynamic_output_buffer_test' );
add_cacheaction( 'add_cacheaction', 'dynamic_output_buffer_init' );
add_cacheaction( 'wpsc_cachedata_safety', 'dynamic_output_buffer_test_safety' );

to use in functions.php, and

if ( function_exists( 'dynamic_output_buffer_test' ) )
      strtest();
    ?>MY_BUFFER_TAG

to use in my theme page.

Now, what if I need more than one section to stay dynamic? I would need to use more than a buffer, but how?
I adjusted the code, in order to output the different dynamic parts, when the function is called from my theme, but I get the same result in all positions. For example, if I want a mini cart widget and another sidebar to stay dynamic, I get two mini carts, the first in its own place, and the second replacing the other sidebar.

Ok,

I figured out how to make the dynamic cache work, using the simple replace method, but I can’t use the output buffer.

This is the code I put inside functions.php file of my theme

function dynamic_output_buffer_test( &$cachedata = 0 ) {
	if ( defined( 'DYNAMIC_OB_TEXT' ) )
		return str_replace( DYNAMIC_OUTPUT_BUFFER_TAG, DYNAMIC_OB_TEXT, $cachedata );

	ob_start();
	// call the sidebar function, do something dynamic
	strtest();
	$text = ob_get_contents();
	ob_end_clean();

	if ( $cachedata === 0 ) { // called directly from the theme so store the output
		define( 'DYNAMIC_OB_TEXT', $text );
	} else // called via the wpsc_cachedata filter. We only get here in cached pages in wp-cache-phase1.php
		return str_replace( DYNAMIC_OUTPUT_BUFFER_TAG, $text, $cachedata );
}
function dynamic_output_buffer_init() {
	add_action( 'wp_footer', 'dynamic_output_buffer_test' );
}
function dynamic_output_buffer_test_safety( $safety ) {
	if ( defined( 'DYNAMIC_OB_TEXT' ) ) // this is set when you call dynamic_output_buffer_test() from the theme
		return 1; // ready to replace tag with dynamic content.
	else
		return 0; // tag cannot be replaced.
}
function strtest() {
  echo "hello";
}

And this is what I put in my template

add_cacheaction( 'wpsc_cachedata', 'dynamic_output_buffer_test' );
 add_cacheaction( 'add_cacheaction', 'dynamic_output_buffer_init' );
 add_cacheaction( 'wpsc_cachedata_safety', 'dynamic_output_buffer_test_safety' );
    ?>MY_BUFFER_TAG

What am I doing wrong here?

Ok,

now I figured out how to make the dynamic cache work, but I have another problem now: I’m using the output buffer but it’s working only with Google Chrome, as the string replacement is not being performed with IE, nor Firefox. Unfortunately, I can’t spot any error and the cache logs the same lines after a page request made by Chrome and a page request made by Firefox or IE.

Any idea about this?

I forgot to replace

add_cacheaction( 'wpsc_cachedata_safety', 'dynamic_output_buffer_test_safety' );

with

add_cacheaction( 'wpsc_cachedata_safety', 'dynamic_cache_test_safety' );

but I’m not able to get things working: I simply don’t see the code replacement.

Hi,
I’m trying to implement the dynamic cache too, but I’m quite lost by now.
I got the dynamic-cache-test.php script, moved into a dynamic-cache-test folder under plugins folder and activated it as a new plugin.
I defined DYNAMIC_CACHE_TEST_TAG, then I edited a page from my theme, switching this code:

<?php woocommerce_mini_cart(); ?>

with this:

<!--mydynamicdata--><br />
    <?php woocommerce_mini_cart(); ?><br />
    <!--/mydynamicdata-->

I expected to see the Hello World text replacing the cart, but I just see the string

–>

before and after the cart widget content.

If I just put my secret string in a template page, that string is removed, but replaced with nothing.

Can you point me to the correct using of the dynamic cache functionality?

Found it!
Thanks a lot!

No, my problem is that I’ve just approached WordPress and I still have to learn how it works. Browsing the code, I found out that content.php is my actual template (for main contents), while page.php lies on a higher level. I’ll keep exploring that, thanks!

Ok, I managed to display blocks from Magento inserting the code (for example the_block(‘top.links’);) in my content.php page. Still, I don’t have any custom php code working when I put it in page.php.
Well, althought I have a bit of experience with Magento, I’m totally new to WordPress, so I think my problems are WordPress related.

Thanks for the great job!
