在PHP中使用多个条件从提交按钮运行MYSQL查询

Question

my code

<form name="rua" method="post">

<input name="Next" type="submit" id="Next" value="Next">                

<?php
if($_REQUEST['Next']=='Next' && (strpos($_POST['ruacombo'], 'Yes') === true && (strpos($drop, 'norm') !== false))) {
{
$sql="UPDATE `RUASEXCELL` SET `$tier_two`=3 WHERE Username = '$username'";
echo $sql;

$final=mysql_query($sql);
if($final)
{
//echo "<meta http-equiv=\"refresh\" content=\"0;URL=\">";
}
} 
}

?>
</form>

next = submit button

ruacombo = combobox populated by mysql

drop = combobox populated by mysql

i have tried a few variations of this code and cannot seem to get it to work

Thanks

Fix this from :

(strpos($drop, 'norm') !== false)

To

(strpos($drop, 'norm') != false)

!== is used to compare if the values are also of the same object type. Which would almost always fail for your case.
