Question

I am using a PHP variable on a public web page as:

<a href="$user_website">

This variable extracts a user’s website address from a mysql database when user inserts his web address into a form in his backoffice. If the user has left the field blank, the dynamic link with the variable in it appears as”

<a href="">

which of course causes the current page to refresh when the link is clicked. I don’t want to create a default link in the mysql database, since I’m already using “http://” as the default for this field for purposes of prompting the user to enter this before “www.website.com” for proper linking where it will appear in the public web page.

How do I create a default value that will be placed inside the <a href=""> in the event the user leaves this field blank in the form provided for him?

Answer 1

Just check if $user_website is empty:

if (!empty($user_website)) {
    echo "<a href='$user_website'>";
} else {
    echo "<a href='http://yourdefaultsite.com'>;
}
