如何在php_mysql中判斷表單是否空決定是否執(zhí)行語句

if ((isset($_POST["MM_insert"])) ($_POST["MM_insert"] == "form1")) {

判斷MySQL表單是否為空可用empty函數(shù)

值來進行判斷。

很簡單的，給一個例子。

php利用

empty函數(shù)

判斷MySQL表單是否為空

方法一:$sql=select*formabc$result=MySQL_query($sql);$row=MySQL_fetch_array($result);if(empty($row))//開始判斷是夠為空{(diào)echonull;}else{echonotnull;}php利用empty函數(shù)判斷MySQL表單是否為空

方法二:$sql=select*formabc$result=MySQL_query($sql);$row=MySQL_fetch_array($result);if(!$row)//開始判斷是夠為空{(diào)echonull;}else{echonotnull;}其實MySQL_fetch_

array函數(shù)

在使用的時候如果表是空表的話，就會返回false，這個時候$row自然沒有賦值成功。記住源碼天空

，千萬不敢這樣用$row=mysql_fetch_array

如果后面喲or

die的話，則程序執(zhí)行到mysql_fetch_array變會終止執(zhí)行。

php+MYSQL提交表單查詢問題

把$query=mysql_query('SELECT * FROM zhengshu WHERE byzbh=$byzbh');

改成$query=mysql_query('SELECT * FROM zhengshu WHERE byzbh='".$byzbh."'');
