I think this will be a simple question for anyone who is familiar with WordPress and PHP. I'm not a PHP guru, so that's why I ask you guys! What we want is simple. Our images have a title and alt desc. But we want to echo them in the theme.

Below is the code where it should be echoed. Yes, I was able to find the piece of code responsible for this ;-). Any suggestions? enter image description here

        while( have_posts() ) :

        the_post();

        $image = wp_get_attachment_image_src( (int)get_post_meta( get_the_ID() , "_thumbnail_id" , true ) , "collection" );
        $large_image = wp_get_attachment_image_src( (int)get_post_meta( get_the_ID() , "_thumbnail_id" , true ) , "original" );

        $terms_array = array();

        $terms = wp_get_post_terms( get_the_ID() , "brand" );

        $brand_image = "";

        $has_brand_names = array();

        foreach( $terms as $term ) :

            if( !$brand_image ) $brand_image = $brand_images["brand-".$term->term_id];

            $terms_array[] = "brand-" . $term->term_id;

            $has_brand_names[ $term->slug ] = true;

        endforeach;

        $terms = wp_get_post_terms( get_the_ID() , "collection_subcategory" );

        foreach( $terms as $term ) :

            $terms_array[] = "subcategory-" . $term->term_id;

        endforeach;

        printf( "<div class='shoe %s' data-image='%s' data-large-image='%s' ><div class='shoe-outer' ><div class='shoe-inner' ><img src='%s' ></div></div></div>", join(" ", $terms_array ), esc_attr( $image[0] ), esc_attr( $large_image[0] ), $brand_image );

    endwhile;

  • You want to display the image with custom title and alt text... right? Are you getting any errors in the above code?

At the top of your code, just after $large_image, you can add this :

$image_alt = get_post_meta((int)get_post_meta( get_the_ID() , "_thumbnail_id" , true ), '_wp_attachment_image_alt', true);
$image_title = get_the_title((int)get_post_meta( get_the_ID() , "_thumbnail_id" , true ));

The alt for attachment is stock in post_meta (_wp_attachment_image_alt), the title is a post_title.

And then your replace the value in your printf().

EDIT:

printf( "<div class='shoe %s' data-image='%s' data-large-image='%s' ><div class='shoe-outer' ><div class='shoe-inner' ><img src='%s' alt='%s' title='%s' ></div></div></div>", join(" ", $terms_array ), esc_attr( $image[0] ), esc_attr( $large_image[0] ), $brand_image, $image_alt, $image_title );

Tell me if it's work :)

  • I'm not really a hero with printf. Could you show me how to modify? I've added them to the printf, but now we have a error.

  • Thanks, but still nothing to see unfortunatly :-(. It is the featured image of a post. I've added an image to show you.

  • Can you try to dump the 2 variables ? $image_alt, $image_title

  • I've dumped them. With $image_title I see the image name because that's the name from the image. But I want the featured post image title. Is this a different field?
