The following provides an infinite grading class code in PHP. Friends who want to implement unlimited grading classes can try it. The bug has been checked and corrected. If you copy the code directly, you can use angle brackets and need to be replaced).
1. There is a b_mtype table in the database ProductShow. The table creation statement is as follows:
<ol class="dp-sql"> <li class="alt"><span><span class="keyword">CREATE</span><span> </span><span class="keyword">TABLE</span><span> `b_mtype` ( </span></span></li> <li class=""> <span> `typeid` </span><span class="keyword">int</span><span>(4) </span><span class="op">NOT</span><span> </span><span class="op">NULL</span><span> </span><span class="keyword">default</span><span> </span><span class="string">'0'</span><span>, </span> </li> <li class="alt"> <span> `typename` </span><span class="keyword">varchar</span><span>(50) </span><span class="op">NOT</span><span> </span><span class="op">NULL</span><span> </span><span class="keyword">default</span><span> </span><span class="string">''</span><span>, </span> </li> <li class=""> <span> `parentid` </span><span class="keyword">int</span><span>(4) </span><span class="op">NOT</span><span> </span><span class="op">NULL</span><span> </span><span class="keyword">default</span><span> </span><span class="string">'0'</span><span>, </span> </li> <li class="alt"> <span> `parentstr` </span><span class="keyword">varchar</span><span>(200) </span><span class="op">NOT</span><span> </span><span class="op">NULL</span><span> </span><span class="keyword">default</span><span> </span><span class="string">''</span><span>, </span> </li> <li class=""> <span> `depth` </span><span class="keyword">int</span><span>(4) </span><span class="op">NOT</span><span> </span><span class="op">NULL</span><span> </span><span class="keyword">default</span><span> </span><span class="string">'0'</span><span>, </span> </li> <li class="alt"> <span> `rootid` </span><span class="keyword">int</span><span>(4) </span><span class="op">NOT</span><span> </span><span class="op">NULL</span><span> </span><span class="keyword">default</span><span> </span><span class="string">'0'</span><span>, </span> </li> <li class=""> <span> `child` </span><span class="keyword">varchar</span><span>(200) </span><span class="op">NOT</span><span> </span><span class="op">NULL</span><span> </span><span class="keyword">default</span><span> </span><span class="string">''</span><span>, </span> </li> <li class="alt"> <span> `orders` </span><span class="keyword">varchar</span><span>(200) </span><span class="op">NOT</span><span> </span><span class="op">NULL</span><span> </span><span class="keyword">default</span><span> </span><span class="string">''</span><span>, </span> </li> <li class=""> <span> </span><span class="keyword">PRIMARY</span><span> </span><span class="keyword">KEY</span><span> (`typeid`) </span> </li> <li class="alt"><span>) TYPE=MyISAM; </span></li> <li class=""><span> </span></li> </ol>
