[SOLVED] Check if variable contains one of multiple qualifying values

Check if variable contains one of multiple qualifying values

<HTML>
  <body>

<?php
echo "<H4>Are you a Male</h4>"
 ?>
<form action ="ifstat.php" method ="post">
  Enter Please: <input type="text" name="val1">
  <input type ="submit" >
  <input type ="reset">
</form>

<?php
  $isMale=$_POST["val1"];
if($isMale =="y" || "yes"){
  echo("You are a Male");
} elseif($isMale =="n" || "no") {
  echo("You are a female");
} else{
  echo("Invalid entry");
}

?>
</body>
</html>

So, this is my program code. I always keep on getting You are a Male as the output even though I type in "n" or some other value rather than y. What's wrong with the code here?

Here is the photo of the output https://i.sstatic.net/Fpk5U.jpg

Solution

You need to change your condition formatting from if($isMale =="y" || "yes"){ to if($isMale =="y" || $isMale =="yes"){

  <body>

<?php
echo "<H4>Are you a Male</h4>"
 ?>
<form action ="ifstat.php" method ="post">
  Enter Please: <input type="text" name="val1">
  <input type ="submit" >
  <input type ="reset">
</form>

<?php
  $isMale=$_POST["val1"];
if($isMale =="y" || $isMale =="yes"){
  echo("You are a Male");
} elseif($isMale =="n" || $isMale =="no") {
  echo("You are a female");
} else{
  echo("Invalid entry");
}
