如何在Wordpress中为get_post_meta编写if语句

Question

I'm trying to right an if statement for get_post_meta. I want to display the info if something is there, if there is nothing, don't display anything. Here is an example I am working with, with no luck.

if(get_post_meta()); echo '<a href="'.get_post_meta($post->ID, 'text', true).'">'; endif;

Any help is appreciated. Thanks.

You've made an error in the syntax. Use

if($condition): statements; endif;
              ^

instead of

if($condition); statements; endif;
              ^

So your code would be

if(get_post_meta()):
    echo '<a href="'.get_post_meta($post->ID, 'text', true).'">';
endif;

That's the alternative syntax for control structures .
You can always use the standard one

if($conition) {
    // statements
    // .....
}
else { 
    // otherweise
}
