Question

How do I insert PHP code into a HTML Button? Here’s what I have:

<input type="submit" value="Buy" onclick="
<?php
    $sq = mysql_query("SELECT * FROM accounts WHERE Username='$usr'");
    $ar = mysql_fetch_array($sq);

    if ($ar['Beevals'] >= 250){
         mysql_query("UPDATE `accounts` SET `Beevals`=`Beevals`-250 WHERE Username='$usr'");
         mysql_query("UPDATE `accounts` SET `Skin`=`WorkersDream` WHERE Username='$usr'");

    }

?>
" />

But it doesn’t work. So, I’m wandering how exactly can you insert PHP code into a HTML Button?

Answer 1

“Inserting PHP into an HTML button” doesn’t make any sense. HTML is for the client’s browser, PHP executes on the server.

Take a look at the PHP tutorial to see a very basic example of how to make a form interact with PHP. To crib from there:

action.php

Hi <?php echo htmlspecialchars($_POST['name']); ?>.
You are <?php echo (int)$_POST['age']; ?> years old.

<form action="action.php" method="post">
 <p>Your name: <input type="text" name="name" /></p>
 <p>Your age: <input type="text" name="age" /></p>
 <p><input type="submit" /></p>
</form>
