I wanted this to display icons for all of the categories an entry belongs to, so I added a clause that simply loops through them, when the value of $icon_cat = “all”. (I also wanted the icons to link to the appropriate category “page”; which is a hack that won’t necessarily port to other sites’ configurations, so that’s left as an exercise for the reader. {smile})
function icon_picker($text)
{
global $icon_path, $icon_url, $icon_align, $icon_ext, $icon_cat;
$content = '';
$cat_names = array();
$cats = get_the_category('');
if($icon_cat == "all")
{
foreach($cats as $category)
{
$cat_to_use = stripslashes($category->cat_name);
if(file_exists($icon_path . $cat_to_use . $icon_ext))
{
$filename = $icon_url . $cat_to_use . $icon_ext;
$content .= "<img class='caticon' src='" . $icon_dir . $filename . "'";
$content .= " align='" . $icon_align;
$content .= "' alt='" . $cat_to_use . " icon' hspace='5' />n";
}
}
$text = $content . $text;
} else {
foreach ($cats as $category)
{
$cat_names[] = stripslashes($category->cat_name);
}
if($icon_cat == "first")
{
$cat_to_use = $cat_names[0];
} else {
$size = sizeof($cat_names);
$cat_to_use = $cat_names[$size - 1];
}
if(file_exists($icon_path . $cat_to_use . $icon_ext))
{
$filename = $icon_url . $cat_to_use . $icon_ext;
$content .= "<img class='caticon' src='" . $icon_dir . $filename . "'";
$content .= " align='" . $icon_align;
$content .= "' alt='" . $cat_to_use . " Icon' />n";
$text = $content . $text;
}
}
return $text;
}
