Sitemap list from multi dimensional array

Go to solution Solved by ozestretch,

I am creating a dynamic human readable sitemap from mysql>php.


the array is created with; (array structure can be altered if this is causing the grief)

$row['category'] = varchar; // list of 10 categories
$row['status'] = int; // 0,1 or 2
$row['id'] = int; // 1,2,3,4... (AI)
// set the title for link
$this->sitemap[$row['category']][$row['status']]['title'][$row['id']] = $row['seo_title'];

// set the url for link
$this->sitemap[$row['category']][$row['status']]['url'][$row['id']] = $row['slug'].".php";

My required output to be as;

      // all category[0][2]
      <li><a href="category[0][2]['title']['the row id']">category[0][2]['title']['the row id']</a></li>
      // all category[0][1]
        <li><a href="category[0][1]['title']['the row id']">category[0][1]['title']['the row id']</a></li>
        // all category[0][0]
          <li><a href="category[0][0]['title']['the row id']">category[0][0]['title']['the row id']</a></li>
  // all category[1][2]
  <li><a href="category[1][2]['title']['the row id']">category[1][2]['title']['the row id']</a></li>

keep in mind where caetgory[0] is a string as key, not an integer.


Any ideas or questions welcomed, thanks.

Thanks trq, made me revisit the way I was thinking. I got it to output as desired, but am wondering if it is efficient.. thoughts?

$output = new GetSitemap('html');
$sitemapout = "";
foreach($output->sitemap as $categorykey => $value){
   $sitemapout.= "
    <ul class='first'>\n";
    // loop first level pages - status = 2
    foreach($output->sitemap[$categorykey][2]['title'] as $cat2key => $cat2value){
        $sitemapout.= "         <li><a href='{$output->sitemap[$categorykey][2]['url'][$cat2key]}'>{$cat2value}</a></li>\n";
    // loop second level pages - status = 1
    $l2 = 0;
    foreach($output->sitemap[$categorykey][1]['title'] as $cat3key => $cat3value){
        if($l2==0){ $sitemapout.= "          <ul class='second'>\n"; }
        $sitemapout.= "             <li><a href='{$output->sitemap[$categorykey][1]['url'][$cat3key]}'>{$cat3value}</a></li>\n";
    if($l2>0){ $sitemapout.= "          </ul><!--// second //-->\n"; }
    // loop third level pages - status = 0
    $l3 = 0;
    foreach($output->sitemap[$categorykey][0]['title'] as $cat4key => $cat4value){
        if($l3==0){ $sitemapout.= "              <ul class='third'>\n"; }
        $sitemapout.= "                 <li><a href='{$output->sitemap[$categorykey][0]['url'][$cat4key]}'>{$cat4value}</a></li>\n";
    if($l3>0){ $sitemapout.= "              </ul><!--// third //-->\n"; }
    $sitemapout.= "    </ul><!--// first //-->\n  </li>\n";
// end loop
echo "<ul>";
echo $sitemapout;
echo "</ul>";
