php+sql2000问题,数组+sql查询条件
PHP SQL Server
$wd1=$_POST['wd1']; //原来是这样sql="select * from xxx where pr_id like '%". $wd1."%'";
//**********************************************************
//现在要做成假如输入:123 王
//sql="select * from xxx where pr_id like '%123%' and name like '%王%'";
//等等就像上面这样,用户输入的条件可能是多个如:123 王 男或者一个
wd1=$_POST['wd1']; //现在接收input数据,
$split_dir = split ('[ ]',$wd1);//我想着转换成数组
//然后sql server2000语句不知道咋写了,不知道我的意思表达明白了没有,我想表达清楚,求解答思路,
sql="???";
回复讨论(解决方案)
真心,不会了啊。。求教。。提前感谢各位!!
$where = "1=1";$arr = array('col1','col2','col3');foreach($split_dir AS $key=>$val){ $where .= " AND ".$arr[$key]." LIKE '%".$val."%' ";}
$arr是需要在where里面出现的字段名,当然了,安全方面的事你自己控制。
这个只是个大概的思路,这个很显然不够完善,因为别人可能输入 123 男 王 或者增加输入之间的空格,这个都需要你自己去控制
嗯。。谢谢我试试
嘿嘿好了。。。。。我是这样写的
$wd1=$_POST['wd1'];
$split_dir = split ('[ ]',$wd1);
$arr = array('编码','名称','类别','型号');
$where2=" ";
for($m=0;$m
{
for($n=0;$n
if($n==(count($arr)-1)){
$where2=$where2.$arr[$n]." like '%".$split_dir[$m]."%'";
}else{
$where2=$where2.$arr[$n]." like '%".$split_dir[$m]."%' or ";
}
}
$where2=$where2." ";
}else{
for($n=0;$n
if($n==(count($arr)-1)){
$where2=$where2.$arr[$n]." like '%".$split_dir[$m]."%'";
}else{
$where2=$where2.$arr[$n]." like '%".$split_dir[$m]."%' or ";
}
}
$where2=$where2." ) and ( ";
}
}
