<?

for ($i = 0; $i < $dwnum; $i++){//$dwnum>3
$dwmyrow = mssql_fetch_array($dwresult);
echo" <td align='center' width='26'><input type='checkbox' name=checkbox[] value=$dwmyrow[banzhu] /></td>";
echo" <td align='center' width='74'>$dwmyrow[banzhu]</td>";
}
$a=count($checkbox);
echo $a;
请问为什么我的$a=0错在那里啦呀!!!!!

$checkbox 这个变量没有赋值啊？

[怡天网]

checkbox[] value=$dwmyrow[banzhu]
这里不是赋值了吗!!!!!!?

晕！
楼主checkbox[] value=$dwmyrow[banzhu] 是HTML表单里的复选框
跟变量赋值是两个感念
例子：
$checkbox[]=$dwmyrow['banzhu'];

那我放在了提交那个页面上还是不行呀
echo"<form id='form2' name='form1' method='post' action='2.php'>";
echo" <table >";
for ($i = 0; $i < $dwnum; $i++){//$dwnum>3
$dwmyrow = mssql_fetch_array($dwresult);
echo" <td align='center' width='26'><input type='checkbox' name=checkbox[] value=$dwmyrow[banzhu] /></td>";
echo" <td align='center' width='74'>$dwmyrow[banzhu]</td>";
}
echo"<tr>";
echo" <td align='center' colspan=4 width=50%><input type='submit' name='Submit' value='提交' /></td>";
echo" <td align='center' colspan=4 width=50%><input type='reset' name='Submit2' value='重置' /></td>";
echo"</tr>";
echo"</table>";

echo"</form>";
?>



2.php
<?
$a=count($checkbox);
?>

2.php的$checkbox改成$_POST['checkbox']
