    <p>I am in a need of function that will encode and decode all the id's of a tree nodes. I function that will check if its a single string or array string or string with delimiters. I am having one plugin for encoding and decoding. here goes my plugin:</p> <p><strong>FIle:encode.class.php</strong></p> <pre><code>&lt;?php /*------------------------- Author: Jonathan Pulice Date: July 26th, 2005 Name: JPEncodeClass v1 Desc: Encoder and decoder using patterns. -------------------------*/ class Protector { var $Pattern = ""; var $PatternFlip = ""; var $ToEncode = ""; var $ToDecode = ""; var $Decoded = ""; var $Encoded = ""; var $Bug = false; var $DecodePattern = ""; function Debug($on = true) { $this-&gt;Bug = $on; } function Encode() { $ar = explode(":", $this-&gt;Pattern); $enc = $this-&gt;ToEncode; if ($this-&gt;Bug) echo "&lt;!-- BEGIN ENCODING --&gt;\n"; foreach ($ar as $num =&gt; $ltr) { switch ($ltr) { case "E": $enc = base64_encode($enc); break; case "D": $enc = base64_decode($enc); break; case "R": $enc = strrev($enc); break; case "I": $enc = $this-&gt;InvertCase($enc); break; } if ($this-&gt;Bug) echo "&lt;!-- {$ltr}: {$enc} --&gt;\n"; } if ($this-&gt;Bug) echo "&lt;!--------------------&gt;\n\n"; @$this-&gt;Encoded = ($enc == $this-&gt;Str) ?

    2. COPlease tell us exactly what you are trying to accomplish. "check for different conditions" is too vague of a goal for us to help you.

    3. COya i am having a tree where i am listing categories and sub categories.... i need to check for different conditions for encoding and decoding the id's that will go to the front end........here i need to check for single string,array of strings,string with delimiters......

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
