I'm trying to customise the breadcrumbs for the Taxonomy pages by adding some code to Template.php. I've done the below which is working but annoyingly results with the following php notice:
Notice: Trying to get property of non-object in allbuyart_breadcrumb() (line 13 of /var/www/vhosts/allbuyart.com/subdomains/drupal7/httpdocs/sites/all/themes/allbuyart/template.php).
Any ideas on how I can change the below code so this notice doesn't appear? It seems to be the variable on line 6 which is causing the above notice: $vid = $term->vid;
function allbuyart_breadcrumb(&$variables) {
$breadcrumb = $variables['breadcrumb'];
$crumbstyling = '<div class="breadcrumbs">';
$tid = (int)arg(2);
$term = taxonomy_term_load($tid);
$vid = $term->vid;
$vocabulary = taxonomy_vocabulary_load($vid);
if(arg(0) != 'taxonomy') {
$lastitem = sizeof($breadcrumb);
$a=1;
foreach($breadcrumb as $value) {
if ($a!=$lastitem){
$crumbstyling .= $value.' > ';
$a++;
}
else {
$crumbstyling .= $value.' > ';
}
}
$crumbstyling .= '<h1>'.drupal_get_title().'</h1></div>';
}
else {
$crumbstyling .='<a href="/">Home</a>'.' > '.'<a href="'.'/'.$term->vocabulary_machine_name.'">'.$vocabulary->name.'</a>'.' > '.'<h1>'.drupal_get_title().'</h1></div>';
}
return $crumbstyling;
}cheers

Usually, that error comes from using an array as an object. Quick check shows that taxonomy_term_load returns an object (according to documentation, anyways). So that leaves two options: or it returns FALSE, or it returns an object that simply doesn't have that property.
Do a var_dump or, if you got the Devel module installed, a krumo to have a look at what exactly's in $term
_
If that truly is the line to which the error refers, dump the $term variable and see what's in it. seems it's not an object.

The following code
will also run when looking at a non taxonomy pages (e.g. when visiting node/13293), therefore the taxonomy_term_load function will receive an invalid tid (in the node case the argument would be 13293, which is the nid and not a valid tid).
Maybe this is why you are receiving the error.
Try confirming that you are looking at a taxonomy page first, before using the argument, with something like:
