vt_resize.php – image_resize deprecated

Pirenko — Tue, 22 Jan 2013 00:01:26 +0000

WordPress 3.5 is here and those who are using the great Victor Teixeira image resize script some warnings might have appeared on your WordPress installation. The image_resize function is still working, but deprecated (in favor of the “wp_get_image_editor” function). This means that it should stop working someday.

I took a look into the code and found a way to replace the old function. The first thing to do is search for the “image_resize” string and comment that line of code (just like shown on the first line of the code below). Then insert the following lines of code:

//$new_img_path = image_resize( $file_path, $width, $height, $crop, NULL, NULL, 100 );
$editor = wp_get_image_editor( $file_path );
if ( is_wp_error( $editor ) )
return $editor;
$editor->set_quality( 100 );
$resized = $editor->resize( $width, $height, $crop );
$dest_file = $editor->generate_filename( NULL, NULL );
$saved = $editor->save( $dest_file );
if ( is_wp_error( $saved ) )
return $saved;
$new_img_path=$dest_file;

This will keep this script working perfectly for the next 30 years! Well, maybe not that long…

Getting Library Image Attributes

I ran across a small problem the last days. I needed to obtain image attributes (title and alt) from WordPress library and pass them to the img HTML tag. Once again, something that’s supposed to be simple, but took me some time.

Here’s how to obtain those elements using the image source link:

//FUNCTION TO GET IMAGE ID FROM SOURCE
function get_attachment_id_from_src ($image_src) {
global $wpdb;
$query = "SELECT ID FROM {$wpdb->posts} WHERE guid='$image_src'";
$id = $wpdb->get_var($query);
return $id;
}
$alt_text = get_post_meta(get_attachment_id_from_src($image_source), '_wp_attachment_image_alt', true);
$title_text = get_post(get_attachment_id_from_src($image_source))->post_title;
//OUTPUT THE IMAGE
echo '';

The variable $image_source is the absolute path to the image that you want to get these attributes. This code works inside the loop and works for images that are inside your WordPress Media Library.

Let’s start with simple stuff. Well at least apparently… It’s incredible how WordPress is such a powerful tool and sometimes you can’t do the simplest things. Here’s a small screencast that will show you how to disable comments on any scenario.
