PHP form post undefined index

Question

I have an issue about HTML post to PHP script. But the values are not posted. My form.php file codes are;

<form action="http://xxxx/valid.php" method="post">

    Name: <input name="Name" value='' type="text" />
    Sur Name: <input name="SurName" value='' type="text" />

    <input id="submit" type="submit" value="Send" />
</form>

and valid.php codes are;

<?php

echo $_POST["Name"];
echo $_POST["SurName"];
foreach($_POST as $key=>$value)
{
    echo "$key=$value";
}

die();
?>

I get the blank page and I get this error.

Undefined index: Name Undefined index: SurName

I working on PHP 5.6 What is wrong?

Its Solved ! Changed the http://xxxx/valid.php to /valid.php and its worked.

did you clicked submit button without providing value to the input tags? — Santhosh Kumar, Feb 13 '19 at 08:36
Can you show us what is output of `var_dump($_POST, $_GET);` in `valid.php` after you submit form? — Justinas, Feb 13 '19 at 08:36
@SanthoshKumar In that scenario key would be still in `_POST`, but with empty values — Justinas, Feb 13 '19 at 08:37

Try this

$Name = isset($_POST['Name']) ? $_POST['Name'] : '';
$SurName = isset($_POST['SurName']) ? $_POST['SurName'] : '';

echo $Name;
echo $SurName;

try this in valid.php file:

<?php
if(isset($_POST["Name"]) && isset($_POST["SurName"])){
    echo $_POST["Name"];
    echo $_POST["SurName"];
    foreach($_POST as $key=>$value)
    {
        echo "$key=$value";
    }
}

I tested your code, all is working fine with me. if the code is correct then the issue is in the configuration of server or installation (something like that.)

check your configuration maybe it can help...

Well if it's solved then cheers...

happy coding...
