Question

I am designing a wordpress page on which i can add my own php code on as well.

I want to be able to add a form that users can enter their post code and based on their post code I wish to display a price.

So far I have come up with this, but need help in adding the IF statement to it:

<form action="" method="post">
Post Code: <input type="text" name="post_code" />
<input type="submit" />
</form>
Your Post Code is: <?php echo $_POST["post_code"]; ?>!<br />
And the price for that post is: 

Can someone help me here please?

Appreciate your help in advance! 🙂

rewritten based on commetns

<?php
//$_POST["post_code"]='SL1 2SA';
$post_price=array('SL1 2SA'=>'1.50', 'SL1 2GP'=>'2.99', 'SL2 3FA'=>'3.47');

$postage=$post_price[$_POST["post_code"]];

if(!empty($postage)){
    echo 'Your Post Code is: '.$_POST["post_code"].'<br>And the price for that post is '. $postage; //1.5
}else{
    echo 'bad post code';
}
