How can I extract only the URL (attribute value src ) from an image generated by the the_post_thumbnail function and assign it to an image?
The result I'm looking for would look something like:
<img src="<?php the_post_thumbnail(); ?>">
If you're in Loop , the post ID is known by WP, so just use the function get_post_thumbnail_id() without parameter. >
If you're out of Loop , it's a matter of using get_post_thumbnail_id($post_id) .
And with this information at hand, use the wp_get_attachment_image_src function that indicates the Leandro .
Example:
$img = wp_get_attachment_image_src( get_post_thumbnail_id() );
echo "<img src='$img[0]' />";
How It Works : The the_post_thumbnail function is a simple encapsulation for the get_the_post_thumbnail function, which in turn ends by calling the wp_get_attachment_image function.
You can do this as follows:
<?php
$imagem = wp_get_attachment_image_src( $attachment_id, $size, $icon );
?>
<img src="<?php echo $imagem[0]; ?>" />
Here's the documentation if you have any questions.
