Instructor profile php error

Hi @pavarnos,

Thanks for posting on the forum.

As described on your following topic that this is only a simple PHP warning message and not an error therefore it is nothing to worry about.

https://wordpress.org/support/topic/php-error-in-content-course-overviewphp

I have tested it on my test site by setting wp debug on but didn’t get the same warning message that you are getting.

It seems from your both above warning messages that it’s related with instructor avatar.

Have you set the instructor avatar or not?

Are you getting any default avatar as instructor avatar?

Please advise.

Kind Regards,

Hi @pavarnos,

Thank you for your detailed reply.

I don’t want you to ignore warnings and also we will not ignore it but will fix it. What i was telling you that not to worry because severity of warning is lesser than error and warning is not error, most users confused between these two.

You will find more information about warning, notices and errors on the following page.

http://php.net/manual/en/errorfunc.constants.php

I could reproduce this warning message on my test site by disabling avatar from Discussion Settings therefore i have notified the plugin developer to fix it.

In the meanwhile to resolve this warning message could you please try editing the following code on line number 2325 in the following coursepress plugin file.

Coursepress plugin file :
plugins\coursepress\includes\classes\class.shortcodes.php

Before Editing :

$doc		 = new DOMDocument();
$doc->loadHTML( get_avatar( $instructor_id, $thumb_size ) );
$imageTags	 = $doc->getElementsByTagName( 'img' );

$content = '';

foreach ( $imageTags as $tag ) {
$avatar_url = $tag->getAttribute( 'src' );
}
?>
<?php
$content .= '<div class="instructor-avatar">';
$content .= '<div class="' . $class . '" style="background: url( ' . $avatar_url . ' );"></div>';
$content .= '</div>';

After Editing :

if(get_avatar( $instructor_id, $thumb_size ) != ''){
$doc		 = new DOMDocument();
$doc->loadHTML( get_avatar( $instructor_id, $thumb_size ) );
$imageTags	 = $doc->getElementsByTagName( 'img' );

$content = '';

foreach ( $imageTags as $tag ) {
	$avatar_url = $tag->getAttribute( 'src' );
}
?>
<?php
$content .= '<div class="instructor-avatar">';
$content .= '<div class="' . $class . '" style="background: url( ' . $avatar_url . ' );"></div>';
$content .= '</div>';
}
