如何让我的 PHP 代码在 Wordpress 的 img src 中工作？

Question

I've been trying to get a small image of an icon inside of my article thumbnail custom fields in Wordpress website. But the image itself isn't loading but the site understands that image is supposed to be there.

This is my PHP code right now

<?php 
$filepath= "<?php bloginfo('template_url'); ?>/img/downarrow.png";
$meta_value = get_post_meta( $post->ID, 'Magamistuba', true ); 
            if  (!empty( $meta_value )) {echo   '<img src="'.$filepath.'">'.$meta_value;}
            else {} 

?>

On this picture it shows how it appears in the console.

Here is how it is when i tryed

$filepath = bloginfo('template_url') ."/img/downarrow.png";

Answer 1

<?php 
$filepath= bloginfo('template_url') ."/img/downarrow.png";
$meta_value = get_post_meta( $post->ID, 'Magamistuba', true ); 
            if  (!empty( $meta_value )) {echo   '<img src="'.$filepath.'">'.$meta_value;}
            else {} 

You are already in PHP mode, so this is how you write it.

Also, never end a PHP script by closing PHP tags.

Answer 2

You don't need to write <?php a second time.

Instead it is sufficient to write:

$filepath = bloginfo('template_url') . '/img/downarrow.png';

Answer 3

<?php 
    $filepath= bloginfo('template_url') . "/img/downarrow.png";
    $meta_value = get_post_meta( $post->ID, 'Magamistuba', true );
    if  (!empty( $meta_value )) {echo   '<img src="'.$filepath.'">'.$meta_value;}
    else {}
?>

Answer 4

That's because $filepath is a String and not PHP code.

You must put your code outside the string and concatenate .

<?php 
$filepath = bloginfo('template_url') ."/img/downarrow.png";
$meta_value = get_post_meta( $post->ID, 'Magamistuba', true ); 

if  (!empty( $meta_value )) {
    echo   '<img src="'.$filepath.'">'.$meta_value;
}

?>

Answer 5

Try with this.

$filepath = get_template_directory_uri()."/img/downarrow.png";
