Why the program always returns $everything

<?php

My "if" clause doesn't work. Programm always returns $everything_OK = true; I would like the clause "if" to return a value $everything_OK = faslse but its never hapeppens. Why?
session_start();

if(isset($_POST['name']))
{

    $everything_OK = true;

    $name = $_POST['name'];
    $surname = $_POST['surname'];
    $date = $_POST['date'];

here is a condition that name user must be met and here is a problem, because this "if" always return $everythink_OK = true

if(strlen($name)<2 || strlen($name)>15 || is_numeric($name))
    {
        $everything_OK = false;
        $_SESSION['e_name'] = '<strong>Podaj prawdziwe imię!</strong>';
    }
    
    // if(strlen($surname)<2 || strlen($surname)>15 || is_numeric($surname))
    // {
    //     $wszystko_OK = false;
    //     $_SESSION['e_surname'] = '<strong>Podaj prawdziwe nazwisko!</strong>';
    // }

    // if($everything_OK = true)
    // {
    //     header("Location: profil.php");
    // } 
}
?>

CodePudding user response：

Your using an assignment: if($everything_OK = true)

You need to use a comparison if($everything_OK == true)

Notice the two equal signs ==

CodePudding user response：

Your POST send the variable name... isset() return always true because is a empty string OR a string. In the 2 cases return true.

You need also to check if is not empty like this:

if(isset($_POST['name']) && $_POST['name'] != '') {...}

CodePudding user response：

You passing name as string value but checking for number

if(strlen($name)<2 || strlen($name)>15 || is_numeric($name))

it's FALSE and never goes through condition.

Can you specify conditions & input params that you use.
