php - Paginating MySQL Results with User Values from HTML Form -

i'm not great php, i've got project working pretty expected. last piece getting pagination work correctly. correctly, mean retaining submitted form values past page 1. looked sessions , seems overkill i'm passing results get.

again, pagination works, doesn't retain form values. i'm working query on same page, figured use $_server['request_uri'], reason when in href of pagination, either breaks page , nothing displayed, or generates url doesn't resolve correctly— myurl.com/$_server['request_uri']?p=2—as opposed having values get.

thoughts on this? think i'm missing character or brackets or (again, php isn't forte).

thanks help!

function pagination($page,$num_page) {   echo'<ul style="list-style-type:none;">';   for($i=1;$i<=$num_page;$i++)   {      if($i==$page) {  echo'<li style="float:left;padding:5px;">'.$i.'</li>'; } else {  echo('<li style="float:left;padding:5px;"><a href="$_server[\'request_uri\']?p='.$i.'">'.$i.'</a></li>'); }   }   echo'</ul>'; } if($num_page>1) {  pagination($page,$num_page); }
