HTML form to PHP function

Question

I have a simple form like this:

<form>
  <label>Subject</label>  
  <input id="subjec_input" name="subject_input" type="text">
  <label>Message Body</label>             
  <textarea id="body_input" name="body_input"></textarea>
  <button id="submit_btn" name="submit_btn">Submit</button>
</form>

I want to take the input from the form and put subject_input into a and body_input into b

<?php send_msg( 2, 'a', 'b' );?>

At the moment I have this code which fires the function on page load but I want it to only fire when the user clicks submit.

I have tried using get but have not been successful

Show us your unsuccessful attempt. This is really basic PHP. — Script47

use $_GET['subject_input'] in place of a and $_GET['body_input'] in place of b — mega6382

if you are using get request then you can do

<?php
$body_input=$_GET['body_input'];
$subject_input=$_GET['subject_input'];

send_msg( 2,$body_input, $subject_input);

if you are using Post Request then your html form tag must define method="POST"

  <?php
    $body_input=isset($_POST['body_input'])?$_POST['body_input']:'';
    $subject_input=isset($_POST['subject_input'])?$_POST['subject_input']:'';

    send_msg( 2,$body_input, $subject_input);

Thanks. I used post because get was changing the URL. Then I used this: stackoverflow.com/a/26380651/1045794 to hide the post. :)

First give your form a method like GET/POST

<form action="welcome.php" method="get">

Then in your PHP code access them with super globals like :

$a = $_GET['body_input']

Then pass those to your function

    if(isset($_POST['submit_btn'])){
    echo $subject_input = $_POST["subject_input"];
     echo $body_input = $_POST["body_input"];
send_msg( 2,$body_input, $subject_input);

 }

You can use it like this

You need to use:

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

 $a = $_POST['subjec_input'];
 $b = $_POST['body_input'];  

 //Run your function/code.

 }

Change your form to method "post" :

 <form action="" method="post">

Also, edit your button to be of type "submit" :

 <button type="submit" id="submit_btn" name="submit_btn">Submit</button>
