Question

I have a php script that outputs a link element within a list element depending on certain conditions being met, the code is as follows:

    global $wpdb;

    function currentURL() {

        $pageURL = 'http';
        if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";}
        $pageURL .= "://";
        if ($_SERVER["SERVER_PORT"] != "80") {
            $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
        } else {
            $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
        }
        return $pageURL;}

    $getUrl = $wpdb->get_results("SELECT option_name,option_value FROM wp_options WHERE option_name = 'siteurl' ");

    $url = $geturl->option_value;

    $getData = $wpdb->get_results("SELECT post_title,guid FROM wp_posts WHERE post_type = 'page' ");

    echo "<ul id=\"mainNavInnerContainer\">"; 

    if(currentURL() == $url){
    echo "<li><a href=\"" . $url . "\" id=\"current\">home</a></li>";}

    else{ echo "<li><a href=\"" . $url . "\">home</a></li>"; }

The problem I’m having is that when I view the element in source code view in my browser i get the following:

<a href>Home</a>

I’m really confused as to why this is, and was hoping that anyone else would have any idea why.

EDIT
I was able to use a foreach loop to put the value in my $url variable but is this good practice? Because I know that the query in $getUrl will always return one row, but still this method seems pretty error prone. Here is the revised $url variable code:

        foreach($getUrl as $urlResult){
        $url = $urlResult->option_value;}

Answer 1

1. add to top of code error_reporting(E_ALL);

2. add check:

   $getUrl = $wpdb->get_results("SELECT option_name,option_value FROM wp_options WHERE option_name = 'siteurl' ");    
       $url = $geturl->option_value;
   var_dump($url);
