警告：mysql_num_rows（）期望参数1是资源，布尔值在

Question

我是php的新手，当我尝试删除记录时，我正在争吵

  

警告：mysql_num_rows（）期望参数1是资源，   / home / ****中给出的布尔值           第49行/public_html/*****/***/purmstdel.php

     

警告：无法修改标头信息 - 已发送的标头   （输出从/home/****/public_html/****/***/purmstdel.php:49开始）   在   /home/natkhatpari/public_html/kevinenterprise.co.in/chandrika/purmstdel.php   在第60行

在这里，我们的代码在下面
