Grodo Posted October 24, 2007 Share Posted October 24, 2007 Hello fellow PHP Freaks, Im having a hard time converting the following tree menu script to read nodes from a text file, rather then a database. This script works perfectly and is exactly what i am looking for, however it relies on query's from a MySQL database (I don't know how to set one up is the real problem). I would like to keep the feature where you can pass a parameter through the script and its expands the corresponding folder. If some one could help me convert this script to read data from a text file; or show me how to setup a MySQL database that would be awesome. Here is the demo of the script im trying to convert / learn how to operate. http://www.myiosoft.com/products/EasyFree/easyphptree/demo/ and is also available for download here: http://www.myiosoft.com/products/EasyFree/easyphptree/easyphptree.zip I have also posted the code for the .php file that is located in the zip file. <? session_start(); error_reporting(E_ALL); // error_reporting(0); // ******************************************************** // ************************ EasyPHPtree ******************* // *********************************************** MyioSoft // ************************** http://www.myiosoft.com/ // // **************************** // Edit Your Myqsl Server Data // **************************** // Server data myio.net $Myqsl["Server"]="localhost"; $Myqsl["User"]="user"; $Myqsl["Pass"]="pass"; $Myqsl["DB"]="dbase"; $Myqsl["Table"]="table"; $install=0; //In order to Create a Tree Example run once with $install=1; then return to $install=0; // // ************************************************************************************** // In order to Create a Tree Example run once with $install=1; then return to $install=0; // ************************************************************************************** $nodes=500; $groups=9; if($install==1){ $Description=""; $CreateUser=""; $CreateDate=""; $ModifyDate=""; $LastVisit=""; $PublicUse=0; $MyqslTable=$Myqsl["Table"]; @mysql_connect($Myqsl["Server"],$Myqsl["User"],$Myqsl["Pass"]) or Die ("<div align=center><font color='red'><b>Error! <br>Cannot make MySQL server connection.</b></font></div>"); mysql_select_db($Myqsl["DB"]); $sql="DROP TABLE IF EXISTS $MyqslTable"; mysql_query($sql); $sql="CREATE TABLE IF NOT EXISTS `$MyqslTable` ( `ID` bigint(20) NOT NULL auto_increment, `Name` varchar(255) NOT NULL default '', `Description` text NOT NULL, `CreateUser` bigint(20) NOT NULL default '0', `CreateDate` datetime NOT NULL default '0000-00-00 00:00:00', `ModifyDate` datetime NOT NULL default '0000-00-00 00:00:00', `LastVisit` datetime NOT NULL default '0000-00-00 00:00:00', `Parent` bigint(20) NOT NULL default '0', `PublicUse` tinyint(1) NOT NULL default '0', PRIMARY KEY (`ID`))"; mysql_query($sql); srand((double)microtime()*1000000); for ($i=1;$i<=$nodes;$i++){ if ($i>$groups){ $parcat=rand(1,100); }else{ $parcat=0; }; $sql="INSERT INTO $MyqslTable(ID,Name,Description,CreateUser,CreateDate,ModifyDate,LastVisit,Parent,PublicUse) VALUES (Null,'Easy $i','$Description','$CreateUser','$CreateDate','$ModifyDate','$LastVisit','$parcat','$PublicUse')"; mysql_query($sql); } print "Created Tree with ".$nodes." nodes in ".$groups." groups"; } // // ************ // HTML OUTPUT // ************ // register_globals = Off compatibility if ($_GET) {foreach (array_keys($_GET) as $var){$$var=strip_tags($_GET[$var]);}} ?> <HEAD><TITLE>Easy PHP Tree</TITLE></HEAD> <BODY> <table cellspacing="0" cellpadding="0" width="750" border="0"> <tr> <? // benchamrk (optional) start time $timeparts = explode(" ",microtime()); $starttime = $timeparts[1].substr($timeparts[0],1); ?> <td width="200" valign="top"><?=MakeTree($Page,$Name,$Myqsl); ?></td> <? // benchamrk (optional) end time $timeparts = explode(" ",microtime()); $endtime = $timeparts[1].substr($timeparts[0],1); $totaltime=bcsub($endtime,$starttime,6); ?> <td valign="top" align="left" width="550"> <div align="center"> <h1>Easy PHP Tree</h1><h2>This is a page for the node</h2> <h1><?=$Name; ?></h1> <h2> Tree with <?=$nodes; ?> nodes in <?=$groups; ?> groups <br>build in <?=$totaltime; ?> sec</h2> <a href="http://myiosoft.com">MyioSoft</a> </div> </td> </tr> </table> </BODY></HTML> <? // // ******************************** // EsayPHPtree functions (73 lines) // ******************************** function MakeTree(&$Page,&$Name,$Myqsl){ $MyqslTable=$Myqsl["Table"]; @mysql_connect($Myqsl["Server"],$Myqsl["User"],$Myqsl["Pass"]) or Die ("<div align=center><font color='red'><b>Error! <br>Cannot make MySQL server connection.</b></font></div>"); mysql_select_db($Myqsl["DB"]); $usage="PublicUse=0 Or PublicUse=1"; $result=mysql_query("SELECT * FROM ".$MyqslTable."
