Question

Example PHP code:

<?php 
    $image_attributes = wp_get_attachment_image_src( '8' );
?> 
 
<img src="<?php echo $image_attributes[0]; ?>" width="<?php echo $image_attributes[1]; ?>" height="<?php echo $image_attributes[2]; ?>">

Now, lets say, I don’t want to use the $image_attributes variable at all, and directly employ wp_get_attachment_image_src( '8' ); instead of $image_attributes[0];, $image_attributes[1]; and $image_attributes[2]; later on with the img tag.

In that case, how should I modify the code?

WHY?

Let me explain by example (my real use case).

<?php 
    $attachment_attributes = wp_get_attachment_image_src( '8' ); // returns an array
?> 
 
<media:content url="<?php echo $attachment_attributes[0]; ?>" width="<?php echo $attachment_attributes[1]; ?>" height="<?php echo $attachment_attributes[2]; ?>" type="image/jpeg">

How do I do the same, like when I am coding it like this?

foreach ( $attachments as $att_id => $attachment ) {
    $attachment_attributes = wp_get_attachment_image_src( '8' );
    
    // Should it be done like this? If not, how do I do it?
    $output .= '<media:content height="' . $attachment_attributes[0]; . '" type="image/jpeg">';

    if ( $captiontag && trim($attachment->post_excerpt) ) {
        $output .= "
            <{$captiontag}>" . wptexturize($attachment->post_excerpt) . "</{$captiontag}>";
    }
    $output .= '
        </media:content>';
}

Answer 1

Not sure why your trying to avoid variables, but you may be able to get away with something like:

<?php

vprintf(
    '<img src="%s" width="%d" height="%d">',
    wp_get_attachment_image_src( '8' )
);

Or, from the code from ‘Why’

<?php

foreach ( $attachments as $att_id => $attachment ) {
    $attachment_attributes = wp_get_attachment_image_src( '8' );

    $output .= '
        <media:content
          url="' . $attachment_attributes[0] . '"
          width="' . $attachment_attributes[1] . '"
          height="' . $attachment_attributes[2] . '"
          type="image/jpeg">';

    if ( $captiontag && trim($attachment->post_excerpt) ) {
        $output .= "
            <{$captiontag}>" . wptexturize($attachment->post_excerpt) . "</{$captiontag}>";
    }
    $output .= '
        </media:content>';
}
