How to take value of an html element to use in php?
Question
I'm trying to use a set of inputs in HTML but I would like to create a PHP onclick function that takes the value of certain elements in HTML when clicked. The problem is I don't think I can use a conventional HTML method="post" form because I'm trying to get the value of something which isn't and I'm trying to get the value of a div .
Specifically, I want to assign a value to each of the squares depending on their color and then use that value to store in a database in PHP. Any help is appreciated.
<?php
session_start();
include("database.php");
if($_SERVER['REQUEST_METHOD'] == "POST")
{
$text_custom = $_POST['text_custom'];
echo $text_custom;
}
?>

although I am not very clear about your question but to use HTML value in PHP you need to put all the HTML tag that consists of the value you wish to save to the database inside a <form action="yourPhpNameWithTheRelatedCode" method="POST"> tag the submit button <button type="submit" name="submit">Submit</button> then in PHP
if (isset($_POST["submit"])){
$value= $_POST["theNameOfTheTagThatYouWishToSaveThatValue"]??"";
}
