[英]How to remove the trailing double arrows “»” from breadcrumbs on the home page only
I found this useful PHP snippet and made a couple small modifications, but I have not been able to figure out how to exclude the home page from showing the trailing "»" after the word "Home". 我发现了这个有用的PHP代码段,并进行了一些小的修改,但是我还无法弄清楚如何排除主页,以免在单词“ Home”之后显示结尾的“»”。 As a result, it ends up looking like this... Home » .
结果,它最终看起来像是... Home» 。
Is there a simple way to remove this without changing the way the breadcrumbs appear on any other page? 是否有一种简单的方法可以删除此内容,而不会更改面包屑在其他任何页面上的显示方式?
<?php
function breadcrumbs($sep = ' » ', $home = 'Home') {
//Use RDFa breadcrumb, can also be used for microformats etc.
$bc = '<div xmlns:v="http://rdf.data-vocabulary.org/#" id="crums">'.$text;
//Get the website:
$site = 'http://'.$_SERVER['HTTP_HOST'];
//Get all vars en skip the empty ones
$crumbs = array_filter( explode("/",$_SERVER["REQUEST_URI"]) );
//Create the home breadcrumb
$bc .= '<span typeof="v:Breadcrumb"><a href="'.$site.'" rel="v:url" property="v:title">'.$home.'</a>'.$sep.'</span>';
//Count all not empty breadcrumbs
$nm = count($crumbs);
$i = 1;
//Loop the crumbs
foreach($crumbs as $crumb){
//Make the link look nice
$link = ucfirst( str_replace( array(".php","-","_"), array(""," "," ") ,$crumb) );
//Loose the last seperator
$sep = $i==$nm?'':$sep;
//Add crumbs to the root
$site .= '/'.$crumb;
//Make the next crumb
$bc .= '<span typeof="v:Breadcrumb"><a href="'.$site.'/" rel="v:url" property="v:title">'.$link.'</a>'.$sep.'</span>';
$i++;
}
$bc .= '</div>';
//Return the result
return $bc;}
?>
<p><?= breadcrumbs() ?></p>
You have to remove the separator character that is put each time after "Home". 您必须删除每次放置在“主页”之后的分隔符。 Add it only if there is something after "Home".
仅在“主页”之后有内容时才添加它。
$crumbs = array_filter( explode("/",$_SERVER["REQUEST_URI"]) );
//Count all not empty breadcrumbs
$nm = count($crumbs);
$i = 1;
// Add first separator if there is at least one crumb
$homesep = $nm == 0?'':$sep;
//Create the home breadcrumb
$bc .= '<span typeof="v:Breadcrumb"><a href="'.$site.'" rel="v:url" property="v:title">'.$home.'</a>'.$homesep.'</span>';
//Loop the crumbs
foreach($crumbs as $crumb){
...
}
