PHP If语句不适用于表单

Question

I am getting unexpected T_ELSES. Please help

<?php
$password = $_POST['password'];
$submit = $_POST['submit'];
if ($password == "lol") {
 if ($password) {
  if ($submit) {
   echo "Logged in";
   }
  } else {
  echo "Wrong Pass";
  }
  } else {
  echo "Please fill in all fields.";
  }
 } else {
 echo "Please click submit";
}
?>

Either it is just saying please click submit or it gives me unexpected errors or it doesn't detect please fill in all fields. Please help me and fix up my code thanks

Question: Whats the problem

Answer 1

It seems to me you require something like this:

<?php
$password = $_POST['password'];
$submit   = $_POST['submit'];
if ($password) {
    if ($password == "lol") {
        if ($submit) {
            echo "Logged in";
        } else {
            echo "Please click submit";
        }
    } else {
        echo "Wrong Pass.";
    }
} else {
    echo "Please fill in all fields.";
}

Note that I am only attempting to fix syntactical issues, I cannot guess the logic of your script.

I have updated to reflect your comment.

<?php
    $password = $_POST['password'];
    $submit = $_POST['submit'];

    if ($password == "lol") 
    {
        if ($password) 
        {
            if ($submit) 
            {
                    echo "Logged in";
            }
        } 
        if(!$password)
        {
                echo "Wrong Pass";
        }
    } 
    if(!$password !== "lol")
    {
                echo "Please fill in all fields.";
    }
    ?>
