关于if和else if语句的functions.php中的Wordpress PHP问题

Question

My Home page is a static custom Login Page for a network multisite with the Theme-my-login plugin running om a Divi child theme. On the login page there is the login itself which works fine, and below that two "action links" for "Register" and "Lost Password". I have two custom pages to link to for both links.

So I edit the child theme's functions.php file. Let’s say you wanted to change the default Register action link to a different URL:

function tml_action_url( $url, $action, $instance ) {
    if ( 'register' == $action )
        $url = 'YOUR REGISTRATION URL HERE';
    return $url;
}
add_filter( 'tml_action_url', 'tml_action_url', 10, 3 );

That works perfectly. If I want to include the lost password link too however:

function tml_action_url( $url, $action, $instance ) {
    if ( 'register' == $action )
        $url = 'YOUR REGISTRATION URL HERE';
    else if ( 'lost password' == $action )
        $url = 'YOUR LOST PASSWORD URL HERE';
    return $url;
}
add_filter( 'tml_action_url', 'tml_action_url', 10, 3 );

it breaks for some reason. Any help much appreciated. I have a feeling I'm not using the correct syntax or something. TIA. Jim

From documentation

Note that elseif and else if will only be considered exactly the same when using curly brackets. When using a colon to define your if/elseif conditions, you must not separate else if into two words, or PHP will fail with a parse error.

Either use elseif instead of else if or use curly brackets like so:

function tml_action_url( $url, $action, $instance ) 
{
    if ( 'register' == $action )
    {
        $url = 'YOUR REGISTRATION URL HERE';
    }
    else if ( 'lost password' == $action )
    {
        $url = 'YOUR LOST PASSWORD URL HERE';'
    }
    return $url;
}
