我可以有一个空的其他PHP

Question

I am working in wordpress and there is a function that is calling for a CSS sheet specific to my template.

Now I have a second template that has a different style sheet.

The current function is an if statement (i.e., if template A, use CSS sheet A), but now I would like to do an if/elseif statement that looks for template A or template B. This way I don't have to write the if statement twice.

I want to know what to do with the else at the end. Can I just leave that blank, or is there a better way to handle that?

Answer 1

You do not have to define an else condition. You can just have if or if/elseif if you want. Here's a reference - http://php.net/manual/en/control-structures.elseif.php

Do you want anything to happen if you are not on Template A or Template B? If not, simply exclude the else statement, and use a conditional like

if ($template-a) {
    // include template a css
} elseif ($template-b) {
    // include template b css
}

If you'd prefer some default behavior happen if you are not on Template A or Template B, use a conditional like

if ($template-a) {
    // include template a css
} elseif ($template-b) {
    // include template b css
} else {
    // include default css or whatever
}
