I gave this some more thought and given size of WP code base (including bundled libraries) it doesn’t seem very realistic to compile such list by hand (and repeat it for every new version – meh). I looked up appropriate static code analysis tool – PHP_CompatInfo and after some tinkering generated following report of extensions … Read more
You have made a mistake in the function wpb_related_pages. Your code should look as below: Updated Code with change needed: // related pages function wpb_related_pages() { # Global $post variable should be called at the start of the function. global $post; $orig_post = $post; $tags = wp_get_post_tags($post->ID); Hope this helps!
get_permalink() is only really useful for single pages and posts, and only works inside the loop. The simplest way I’ve seen is this: global $wp; echo home_url( $wp->request ) $wp->request includes the path part of the URL, eg. /path/to/page and home_url() outputs the URL in Settings > General, but you can append a path to … Read more
I’d probably do something like this: Then if i want a Student where i know the ID: Or if i have an array of the db row: Technically you’re not building multiple constructors, just static helper methods, but you get to avoid a lot of spaghetti code in the constructor this way.
You can use the fgets() function to read the file line by line:
\n is a line break. /n is not. use of \n with 1. echo directly to page Now if you are trying to echo string to the page: output will be: you won’t get garden in new line because PHP is a server-side language, and you are sending output as HTML, you need to create line breaks in HTML. HTML doesn’t understand \n. You … Read more
Only double quoted strings interpret the escape sequences \r and \n as ‘0x0D’ and ‘0x0A’ respectively, so you want: Single quoted strings, on the other hand, only know the escape sequences \\ and \’. So unless you concatenate the single quoted string with a line break generated elsewhere (e. g., using double quoted string “\r\n” or using chr function chr(0x0D).chr(0x0A)), the only other way to have a line break … Read more
32767 + 1 is a power of 2 Binary representation of numbers uses powers of 2. So, in an 4-bit structure, 0101 is 2^0 x 1, 2^1 x 0, 2^2 x 1, and 2^3 x 0 which is 5. The MSB is used for sign and unsigned integers.
Use brackets to group the OR statements. You can also use IN
PHP uses one of two methods to keep track of sessions. If cookies are enabled, like in your case, it uses them. If cookies are disabled, it uses the URL. Although this can be done securely, it’s harder and it often, well, isn’t. See, e.g., session fixation. Search for it, you will get lots of SEO advice. The conventional wisdom … Read more
