Hello,

I would like to insert automatically a block after “n” paragraph in my pages and in my articles (same number of paragraph for both)

I’v found in this forum this code for articles :

add_shortcode('portable_hook', function($atts){
ob_start();
$atts = shortcode_atts( array(
'hook_name' => 'no foo'
), $atts, 'portable_hook' );
do_action($atts['hook_name']);
return ob_get_clean();
});
add_filter( 'the_content', 'insert_featured_image', 20 );
function insert_featured_image( $content ) {
global $post;
$inserted_hook = do_shortcode('[portable_hook hook_name="after_first_paragraph"]');
if ( is_single() && ! is_admin() ) {
return prefix_insert_after_paragraph( $inserted_hook, 5, $content ); //Changer le chiffre pour indiquer le paragraphe après lequel le bloc est inséré
}
return $content;
}
function prefix_insert_after_paragraph( $insertion, $paragraph_id, $content ) {
$closing_p = '</p>';
$paragraphs = explode( $closing_p, $content );
foreach ($paragraphs as $index => $paragraph) {
if ( trim( $paragraph ) ) {
$paragraphs[$index] .= $closing_p;
}
if ( $paragraph_id == $index + 1 ) {
$paragraphs[$index] .= $insertion;
}
}
return implode( '', $paragraphs );
}

It works perfectly for articles. Is it possible to change it for applying it both on pages and articles ?

Have a nice day !

Hi there,

this line:

if ( is_single() && ! is_admin() ) {

Change it to:

if ( ( is_page() || is_single() ) && ! is_admin() ) {

Hello David,

Thanks for your answer. Unfortunatly, it does not seem to work. Block appears in articles but not in pages.

Hi Ben,

For reference, could you share a link to a page where that should work on your site?

Did you set the GP Element to display on pages too ?

Oups, yeah that’s it. I’ve set the pages in exclude, not include … Thanks for your help !

And could it be possible to set more than one block in the same page / article ?

In that original snippet there is the function that filters the_content
you can create another function to add a different hook in a different place

For example:


add_filter( 'the_content', 'insert_custom_hook_one', 20 );
    function insert_custom_hook_one( $content ) {
    global $post;
    $inserted_hook = do_shortcode('[portable_hook hook_name="after_another_paragraph"]');
    if ( is_single() && ! is_admin() ) {
        return prefix_insert_after_paragraph( $inserted_hook, 10, $content ); //Changer le chiffre pour indiquer le paragraphe après lequel le bloc est inséré
    }
    return $content;
}

1. we use a new function name here: eg. insert_custom_hook_one

add_filter( 'the_content', 'insert_custom_hook_one', 20 );
    function insert_custom_hook_one( $content ) {

2. here we define a new hook name eg. after_another_paragraph
$inserted_hook = do_shortcode('[portable_hook hook_name="after_another_paragraph"]');

3. and here we set the nth paragraph to 10
return prefix_insert_after_paragraph( $inserted_hook, 10, $content ); here we dei

Thanks a lot David. I forget to change the name of the second function, that’s why I had an error …

Thanks again for your big help !

Hello @David, I have an another question about this code : I wish to exclude some pages in order the custom block does not appear on those pages

I modify the code with that :
```
$excluded_ids = array('4572', '11');
if (((is_page() || is_single()) && !is_admin()) && !in_array(get_the_ID(), $excluded_ids))  {
```
Is this ok and safe to do like this ? (it works but like I’m not use to php code, I would like the confirmation of an expert 🙂 )

That method is perfectly fine.
But if you’re using a GP element to hook content into your custom hook, then you could simply edit the elements display rules and exclude the pages there.

@David : Haha you’re rigth, considerably easier ! 😀

And I would like you’re advise : I’ve found a plugin, “adinserter”. I think it could be useful too for insert blocks inside articles, etc… but I have to code the layout I wish in HTML/CSS

So, is this possible to create a specific block with GenerateBlocks and have a shortcode for it ? (because I can use shortcode with this plugin)

Should be great for making easily “read more” boxes inside articles, custom ads in sidebar or anywhere else, etc … 🙂
