Hi,
Yes you’d have to write out the code for all the places where you have images. If you have the images in a repeaterfield you do not however.. If you’re looking to create an gallery I’d suggest you take a look at the gallery field add on. With that you retrieve the alt text per default.
If you prefer you could just create a function for this to simplify your code in the template. Put this in functions.php
function get_image_with_alt($imagefield, $postID, $imagesize = 'full'){
$imageID = get_field($imagefield, $postID);
$image = wp_get_attachment_image_src( $imageID, $imagesize );
$alt_text = get_post_meta($imageID , '_wp_attachment_image_alt', true);
return '<img src="' . $image[0] . '" alt="' . $alt_text . '" />';
}
And then all it like this where you want the image in your template:
<?php echo get_image_with_alt('NAME OF THE IMAGE FIELD', get_the_ID(), 'thumbnail'); ?>
Note that the last parameter in the function is optional and it’s for if you want another image size than full.
