connect radiobuttons to script

[ipeteweb]

in payment script need to make 3 radio buttons
How can I create 3 radio buttons with different values and connect it to script, so price change depending on the selected radio button?

originally price have only one value:
$shoppingCart = array(
'price' => 0.30,
);

it work with it
$macFields = array(
'VK_AMOUNT' => to_banklink_ch ($shoppingCart['price']),
);

and form for button looks like:
Форма кнопки выглядит:
<form method="POST" action="<?php echo $banks[ $preferences['bankname'] ]['url']; ?>">
<?php
foreach ($macFields as $f => $v) {
echo '<input type="hidden" name="' . $f . '" value="' . htmlspecialchars ($v) . '" />' . "\n";
}
?>
<table cellpadding="0" cellspacing="0" border="0">

<tr>
<td colspan="2" align="center"><input type="submit" value="pay" /></td>
</tr>
</table>

</table>
</form>

Code: Select all

<form>
<input type="radio" name="sex" value="male">Male<br>
<input type="radio" name="sex" value="female">Female
</form>


creates a simple form with 2 options. They share the same name, so only one can be selected at a time. When sent via form, $_POST['sex'] will contain the value of the selected option as specified by the value attribute. So your decision making in the form processing page would look at $_POST['yourRadioButtonName'] (assuming you're posting form instead of using GET variables.

here is an example to play with , I'm sure you can get it.

Code: Select all


<?php

if (!$_POST) { //display the form since we're not responding to it yet
    echo '
<form method="POST" action="' . $_SERVER['PHP_SELF'] . '">
<input type="text" name="cost" value="" /><br />    
<input type="radio" name="pay" value="25" />25<br />
<input type="radio" name="pay" value="50" />50<br />
<input type="radio" name="pay" value="75" />75<br />
<input type="radio" name="pay" value="100" />100<br />
<input type="submit" value="Multiply the text box by the radio button" />
</form>';
} else { //process form 
    //first for demonstration purposes; here's what we're working with:
    echo '<pre>';
    print_r($_POST);
    echo '</pre><br />';
    echo 'The answer is ' . $_POST['cost'] * $_POST['pay'];
}
