Theme Options: If There is No Input, Don’t Display?

by

I have built a custom options panel which allows site owners to enter their social profiles. I then use the second code to make the links appear in the theme.

When no link is entered in the options panel, I would like there to be no link called on the page where the code is being called. Currently, it provides me with a link to the homepage of my site.

Take a look: http://themeforward.com/demo2/ – the green box is the facebook link, the purple is the google link

I know what you’re thinking – why not just leave it the way it is? Because, I’m styling each link with a background image rather than using normal text links… so if I just leave it this way we will still have an image showing up advertising a social site presence, but it won’t be linked. The styling can be found here: http://pastebin.com/m3PrBDae I think that may be affecting this.

In my functions

array( "name" => "Facebook Page",
    "desc" => "Enter your Facebook address. (Must include http://)",
    "id" => $shortname."_facebook",
    "type" => "text",
    "std" => ""),

array( "name" => "Google Plus",
    "desc" => "Enter your Google Plus address. (Must include http://)",
    "id" => $shortname."_google_plus",
    "type" => "text",
    "std" => ""),

How I call them

<a href="https://wordpress.stackexchange.com/questions/34948/<?php echo get_option("to_google_plus'); ?>"></a>

Check if get_option returns a value and if it is not blank, then output the links.
This should work for you:

<?php
if(get_option('to_facebook') && get_option('to_facebook') != '') {
     ?>
     <a href="https://wordpress.stackexchange.com/questions/34948/<?php echo get_option("to_facebook'); ?>"></a>
    <?php     
}   
if(get_option('to_google_plus') && get_option('to_google_plus') != '') {
    ?>
    <a href="https://wordpress.stackexchange.com/questions/34948/<?php echo get_option("to_google_plus'); ?>"></a>
    <?php
}
?>
