I've been banging my head on the wall trying to filter my posts to remove the http: protocol from the img src and I think I may have found a solution. Does anybody see anything wrong with this solution within the loop:
$content = get_the_content();
$content = str_replace(array('http:', 'https:'), '', $content);
echo $content

Reset to default 8The code you provided could cause issues with 3rd party URLs in hyperlinks not running https. You can fix this by including your home url, e.g:
$content = str_replace( set_url_scheme( home_url(), 'http' ), set_url_scheme( home_url(), 'relative' ), $content);
Next, you're applying this when you'd like to display the content, which means you need to do an additional step. Namely, you need to apply a filter called the_content which does some final processing, such as creating paragraphs etc:
$content = get_the_content();
$content = str_replace( set_url_scheme( home_url(), 'http' ), set_url_scheme( home_url(), 'relative' ), $content);
$content = apply_filters( 'the_content', $content );
echo $content
Finally, for maximum compatibility, just call the_content();, and use the the_content filter to do your modification:
add_filter( 'the_content', 'brandozz_url_filter' );
function brandozz_url_filter( $content ) {
$content = str_replace( set_url_scheme( home_url(), 'http' ), set_url_scheme( home_url(), 'relative' ), $content);
return $content;
}
Filters and hooks can go inside a plugin or functions.php, this is what it looks like as a plugin:
/**
* Plugin Name: Relative local URLs
* Plugin URI: http://wordpress.stackexchange/questions/174228/remove-the-http-protocol-from-images
* Description: Replaces http:// URL containing the home url, with relative protocol urls
* Version: 1.0.0
* Author: Tom J Nowell
* Author URI: http://tomjn/
*/
add_filter( 'the_content', 'tomjn_filter_relative_content_urls' );
function tomjn_filter_relative_content_urls( $content ) {
$content = str_replace( set_url_scheme( home_url(), 'http' ), set_url_scheme( home_url(), 'relative' ), $content);
return $content;
}
