Function returning: Warning: Missing argument 1

  • Hey there guys!
    I wrote this couple of functions, that alternate a exploded Custom Field string with the post permalink:

    (where the Custom Field should look like this: ex. Google++https://google.com”)

    // Custom Permalink
function custom_permalink($url){
    global $post;
    $link = get_post_meta($post->ID,'link',true);
    if ($link) {
        $pieces = explode("++", $link);
        $url = $pieces[1];
    } else {
        $url = the_permalink();
    }
    return $url;
}

// Via Text
function via_text($url){
    global $post;
    $link = get_post_meta($post->ID,'link',true);
    if ($link) {
        $pieces = explode("++", $link);
        $url = ' <span><a href="'.$pieces[1].'">Via '.$pieces[0].'</a></span>';
    } else {
        $url = ' ';
    }
    return $url;
}

    … which work all right when tested on a MAMP server, but when deployed they return:

    “Warning: Missing argument 1 …”

    Any idea why this might be happening?

    The strangest thing is that even when deployed the functions return the expected outcome after the “Warning: Missing argument 1…” leyend

    ex.

    <div id="excerpt">
Lorem ipsum dolor sit amet...
<br>
<b>Warning</b>
: Missing argument 1 for via_text(), called in /home/.../index.php on line 24 and defined in
<b>/home/.../functions.php</b>
on line
<b>80</b>
<br>
<span>
<a href="https://google.com">Via Google</a>
</span>
</div>

    Ok… I figured it out…
    this happens when a class gets instantiated and theres no default argument for the constructor…

    here are the working functions…

    // Custom Permalink
	function custom_permalink($url='') {
		global $post;
		$link = get_post_meta($post->ID,'link',true);
		if ($link) {
			$pieces = explode("++", $link);
			$url = $pieces[1];
		} else {
			$url = the_permalink();
		}
		return $url;
	}

	// Via Text
	function via_text($url='') {
		global $post;
		$link = get_post_meta($post->ID,'link',true);
		if ($link) {
			$pieces = explode("++", $link);
			$url = ' <span><a href="'.$pieces[1].'">Via '.$pieces[0].'</a></span>';
		} else {
			$url = ' ';
		}
		return $url;
	}

    in case anyone is in need…
    what they do:

    in case theres a post with the Custom Field ‘link’ (like so: Google++https://google.com) the function will replace the permalink with the Custom Link. So in the theme call: echo custom_permalink(); … instead of the_permalink();

    the via_text() function works a little different; it calls a span tag with the Custom Field ‘link’ exploded like so:

    <span><a href="https://google.com">Via Google</a></span>

    hope this works for somebody else

    ??
