alt attribute on post-image

Hi there,

silly question - have you added an Alt tag to the image?

David, if there is no alt tag, can I pick post_title for alt....

You could try this:

add_filter( 'wp_get_attachment_image_attributes', function( $atts ) {
    if ( empty( $atts['alt'] ) ) {
        $atts['alt'] = the_title_attribute( 'echo=0' ),
    }

    return $atts;
} );

Not sure if it will work or not, but worth a shot.

Thanks Tom, following code working, now it does not show empty alt"", it takes aticle's title as alt attribute. It is helpful in a big and old website, where you do not have mentioned alt while uploading images ... (this can be included in GP as well; rather showing empty alt"")

Regards.

add_filter( 'wp_get_attachment_image_attributes', function( $atts ) {
    if ( empty( $atts['alt'] ) ) {
        $atts['alt'] = the_title_attribute( 'echo=0' );
    }
    return $atts;
} );

Glad it worked! :)

Hi! This code works great.

However, when putting a site on PHP8 (from 7.4) it's giving this error in the PHP error log:

PHP Warning: Undefined variable $post_id in /home/username/public_html/wp-content/plugins/code-snippets/php/snippet-ops.php(505) : eval()'d code on line 2

Is there a tweak that can be done to make it play nicely with PHP8?

Thanks!

Hi there,

your error points to Undefined variable $post_id - and that snippet isn't using the $post_id variable.
Do you have any other snippets ?

Ah, sorry David. Me being a twit on a Monday morning...

The snippet I've got (to put the post title as featured image alts) is:

add_filter( 'wp_get_attachment_image_attributes', function( $atts ) {
    if ( get_post_type( $post_id ) === 'post' ) {
        $atts['alt'] = the_title_attribute( 'echo=0' );
    }
    return $atts;
} );

I was sure I got it from here - but apparently not!

Oh no worries, my brain is super foggy today lol

Try:

add_filter( 'wp_get_attachment_image_attributes', function( $atts ) {
    if ( get_post_type( get_the_ID() ) === 'post' ) {
        $atts['alt'] = the_title_attribute( 'echo=0' );
    }
    return $atts;
} );

Aha - brilliant!

Thanks :)

You're welcome
