I am working on an email subscribe feature on my website. I encountered an issue where the php is not getting the form values. I have looked at numerous threads on this issue and have not had any luck.

So, how can I get the value of the email field in php?

<div>
  <form action="/email.php">
    <label for="fname">First Name</label>
    <input type="text" id="fname" name="firstname" placeholder="Your name..">

    <label for="lname">Last Name</label>
    <input type="text" id="lname" name="lastname" placeholder="Your last name..">
    <label for="email">Email</label>
    <input type="text" id="email" name="email">


    <input type="submit" value="Submit">
  </form>
</div>

Email.php

<?php
$email = $_POST["email"];
    echo $email;
?>

don't use / before email.php and you forgot method type

<div>
  <form action="email.php" method='POST'>
    <label for="fname">First Name</label>
    <input type="text" id="fname" name="firstname" placeholder="Your name..">

    <label for="lname">Last Name</label>
    <input type="text" id="lname" name="lastname" placeholder="Your last name..">
    <label for="email">Email</label>
    <input type="text" id="email" name="email">


    <input type="submit" value="Submit">
  </form>
</div>

PHP not getting value from html, don't use / before email.php and you forgot method type <div> <form action="​email.php" method='POST'> <label for="fname">First Name</label> <input  Without the name attribute specified for each element contained in the form, PHP will be unable to create an array automatically with an access key by using the element's name attribute value. This means you can't access that element form data value after the form has been submitted to the server because its key is undefined.

add form method Attribute get or post

<form action="/email.php" method = "POST">

These strings need some encoding/escaping in order to become strings of non-conflicting characters

Try this way,

HTML:

<form action="email.php" method='POST'>
    <label for="fname">First Name</label>
    <input type="text" id="fname" name="firstname" placeholder="Your name..">

    <label for="lname">Last Name</label>
    <input type="text" id="lname" name="lastname" placeholder="Your last name..">
    <label for="email">Email</label>
    <input type="text" id="email" name="email">


    <input type="submit" name="save" value="Submit">
</form>

PHP:

<?php
    if(isset($_POST["save"]))
    {
        print_r($_POST);
        echo $_POST["email"];
    }
?>

This will helpful to you.

PHP and HTML - Manual, What encoding/decoding do I need when I pass a value through a form/URL? How do I get all the results from a select multiple HTML tag?

PHP and Text Boxes on HTML Forms If you've been following along from the previous sections then your basicForm.php now has a METHOD and ACTION set. We're going to use these to process text that a user has entered into a text box.

Every thing written perfectly, just fault's in form tag, remove "/" from action and give method="POST" in form tag. As you are calling that value with post method in email.php, you have to give the post method on form like this:-

<div>
  <form action="email.php" method="POST">
  <label for="fname">First Name</label>
  <input type="text" id="fname" name="firstname" placeholder="Your name..">

  <label for="lname">Last Name</label>
  <input type="text" id="lname" name="lastname" placeholder="Your last name..">
  <label for="email">Email</label>
  <input type="text" id="email" name="email">


  <input type="submit" value="Submit">
 </form>
</div>

rest is all fine now you can call that value:-

<?php
 $email = $_POST["email"];
 echo $email;
?>
