帮忙看看修改数据库数据代码是否有错~!!!!
include 'include.php';
$id=$_POST['sid'];
$recname=$_POST['Recname1'];?
$description=$_POST['Description1'];
$requirements=$_POST['Requirements1'];
//这四个数据都已经传过来没,现在的错误就是修改失败,感觉应该是数据库修改的语句有误,但是我查了好多资料,还是没有找到答案,希望各位大侠帮忙解决下

if ($requirements==""){
echo "<script>window.open('addment.php','I2_2');alert(\"请输入职业要求!!!\");</script>";
}else {
$query="update recruitment set Recname='$recname' description='$description' requirements='$requirements' where id='$id'";
echo $query;
$result=mysql_query($query);
if(mysql_affected_rows()>0){
echo "<script>window.open('modment.php','I2_2');alert(\"修改成功!!!\");</script>";
}else{
echo "<script>window.open('modment.php','I2_2');alert(\"修改失败!!!\");</script>";
}
}

?>

------解决方案--------------------
$query="update recruitment set Recname='$recname' ,description='$description', requirements='$requirements' where id='$id'";
------解决方案--------------------
$query="update recruitment set Recname='$recname',description='$description' ,requirements='$requirements' where id='$id'";
字段之间用逗号隔开
------解决方案--------------------
$result=mysql_query($query) or die(mysql_error());
看报神马错
------解决方案--------------------
将你的sql 输出 到phpmyadmin执行看看是否正常
------解决方案--------------------
1、字段间要用逗号分开,这是规则,不能讨价还价的
2、确认传入的数据中的特殊字符已经被转义了
------解决方案--------------------
字段间不用逗号隔开的我还是头一次见。没用过。
$query=" update recruitment set Recname='{$recname}' ,description='{$description}', requirements='{$requirements}' where id='{$id}' ";
你拿着输出的sql语句去数据库执行,看看会不会报错。
