Display the title of the image

Instead of : $post_title = get_the_title($ID);

I do :

$postID = get_the_id();
$Images = & get_children( 'post_type=attachment&post_mime_type=image&post_parent='.$postID );
foreach( $Images as $NewImage ){ $post_titles[] = $NewImage->post_content; }
foreach($post_titles as $post_title){
	//CODE OF FUNCTION pibfi_Engine
}

And add :

$replacement = '<span class="pibfi_pinterest">
	<img%1$ssrc="%2$s.%3$s"%4$s>
	<span class="xc_pin" onclick="pin_this(event, \''.
	$pinterest_base_url.
	'?url='.esc_url($post_url).
	'&media=%2$s.%3$s'.'&description='.$image["title"].'\')">
	</span>
</span>';

at the beginning of foreach( $images as $image ){ }

Hi,
Here the all code for pibfi_Engine function :

function pibfi_Engine($content) {
	global $post;
	$post_url = get_permalink(); //Get the post URL
	//$post_title = get_the_title($ID); //Get the post title

	$pinterest_base_url = 'http://pinterest.com/pin/create/button/'; //Pinterests URL to create a Pin

	$postID = get_the_id();
	$Images = & get_children( 'post_type=attachment&post_mime_type=image&post_parent='.$postID );

	foreach( $Images as $NewImage ){
		//$post_titles[] = $NewImage->post_title;
		$post_titles[] = $NewImage->post_content;
	}

	foreach($post_titles as $post_title){
		$content = pibfi_Engine_normalize_image_paths( $content );

		// Show the pin just in images with the 'pinthis' class
		if ( get_option('ppibfi_img_pinthis') == 'on' ) {
			$content = pibfi_Engine_add_pin( $content, $pinterest_base_url, $post_url, $post_title );
		} else {

			// Show on index.php / home page:
			if (get_option('ppibfi_pg_index') == "on" && is_home()) {
				$isOpted = get_post_meta($post->ID, 'xcp_optin_post');
				if ($isOpted[0] != "on") {
					$content = pibfi_Engine_add_pin( $content, $pinterest_base_url, $post_url, $post_title );
				}
			}

			// Show on single.php:
			elseif (get_option('ppibfi_pg_single') == "on" && is_single()) {
				$isOpted = get_post_meta($post->ID, 'xcp_optin_post');
				if ($isOpted[0] != "on") {
					$content = pibfi_Engine_add_pin( $content, $pinterest_base_url, $post_url, $post_title );
				}
			}

			// Show on page.php:
			elseif (get_option('ppibfi_pg_page') == "on" && is_page()) {
				$isOpted = get_post_meta($post->ID, 'xcp_optin_post');
				if ($isOpted[0] != "on"){
					$content = pibfi_Engine_add_pin( $content, $pinterest_base_url, $post_url, $post_title );
				}
			}

			// Show on category.php / archive.php:
			elseif (get_option('ppibfi_pg_cat') == "on" && is_category()) {
				$content = pibfi_Engine_add_pin( $content, $pinterest_base_url, $post_url, $post_title );
			}
		}

	}//foreach($post_titles as $post_title)

	// Print out the content with the changes on images
	return $content;
}

And the all code for pibfi_Engine_add_pin function :

/* This function adds the pin at each post's image */
function pibfi_Engine_add_pin( $content, $pinterest_base_url, $post_url, $post_title ){
	// I had to change this string in order to use the sprintf function.
	// Regular expression that finds all post's images
	$pattern = '/<img(.*?)src=[\'"](.*?).(bmp|gif|jpeg|jpg|png)[\'"](.*?)>/i';
	// Array to store the images that matches
	$matches = array();
	// Execute the regular expression
	preg_match_all($pattern, $content, $matches);
	// Array to store the images and its properties
	$images = array();
	// Image count
	$image_count = 0;
	// Loop to join the tag image properties with its matches
	for( $i = 0; $i < sizeof($matches[0]); $i++ ){
		$images[ $image_count ]['tag'] = $matches[0][$i];
		$images[ $image_count ][1] = $matches[1][$i]; // match 1 - content before the src attr
		$images[ $image_count ][2] = $matches[2][$i]; // match 2 - image url without extension
		$images[ $image_count ][3] = $matches[3][$i]; // match 3 - the extension
		$images[ $image_count ][4] = $matches[4][$i]; // match 4 - content after the src attr

		$pos = strpos($matches[1][$i], "title");
		if($pos === false){
			$pos = strpos($matches[4][$i], "title");
			$title = substr($matches[4][$i], $pos+7);
		}
		else{
			$title = substr($matches[1][$i], $pos+7);
		}
		$pos_end = strpos($title, '"');
		$title = substr($title,0,$pos_end);
		$images[ $image_count ]['title'] = str_replace('"', '',$title);

		$image_count++;
	}
	// Loop to check if any image has the 'needed' pin class: pinthis (pibfi_ShowButton)
	$any_image_has_the_needed_pin_class = ( get_option('ppibfi_img_pinthis') == 'on' ) ? true : false;
	for( $i=0; $i < sizeof( $images ); $i++ ){
		$needed = pibfi_Engine_check_if_the_image_has_pinthis_class( $images[ $i ][ 'tag' ] );
		if( $needed ){
			$any_image_has_the_needed_pin_class = true;
		}
		$images[ $i ][ 'pinthis' ] = $needed;
	}
	// Loop to replace the normal tag by the html with the pin, if it is necessary
	foreach( $images as $image ){
		$replacement = '<span class="pibfi_pinterest">
			<img%1$ssrc="%2$s.%3$s"%4$s>
			<span class="xc_pin" onclick="pin_this(event, \''.
			$pinterest_base_url.
			'?url='.esc_url($post_url).
			'&media=%2$s.%3$s'.'&description='.$image["title"].'\')">
			</span>
		</span>';
		// If the post has any image with the (pibfi_ShowButton) class, the pin'll be showed in just these images
		if( $any_image_has_the_needed_pin_class ){
			if( $image[ 'pinthis' ] ){
				$image_tag = sprintf( $replacement, $image[1], $image[2], $image[3], $image[4]);
				$content = str_replace( $image['tag'], $image_tag, $content);
			}
		} else {
			// Check if the image should or shoudn't has the pin
			if( pibfi_Engine_check_if_the_image_has_the_forbidden_class( $image['tag'] ) ){
				// If it shoud do the replacement
				$image_tag = sprintf( $replacement, $image[1], $image[2], $image[3], $image[4]);
				$content = str_replace( $image['tag'], $image_tag, $content);
			}
		}
	}
	return $content;
}

That’s all ^^

The “title” must be completed for images that this piece of code works.

De nada 😉

Hi elledee

Have you a title for your image ?

After
foreach( $Images as $NewImage ){ $post_titles[] = $NewImage->post_content; }

Try a var_dump of $post_titles, there are a result ?
