Modifying function for checkboxes

Hello!
Need a little modification to this function. Right now, it's for a custom post type. Someone types a value in a text box and saves it. Then it can be retrieved.

However, instead of a text box, I need to have a few checkboxes that save whether or not they are checked. Then I need a way to retreive that value: "if box 1 is checked, display this:" "if box 2 is checked, display this:".



<?php

	add_action("admin_init", "admin_init");

	add_action('save_post', 'save_price');



	function admin_init(){

		add_meta_box("prodInfo-meta", "Product Options", "meta_options", "product", "side", "low");

	}



	function meta_options(){

		global $post;

		$custom = get_post_custom($post->ID);

		$price = $custom["price"][0];

?>

	<label>Price:</label><input name="price" value="<?php echo $price; ?>" />

<?php

	}



function save_price(){

	global $post;

	update_post_meta($post->ID, "price", $_POST["price"]);

}

?>

meta box...



function meta_box($post){

	if ($post->ID >= 1) {

		$_checkbox_1 = get_post_meta($post->ID, '_checkbox_1', true);

		$_checkbox_2 = get_post_meta($post->ID, '_checkbox_2',  true);

	} 

?>

<table width="100%"> 

	<tr>

		<th style="padding:5px; "><label for="_checkbox_1" style="text-align:left;">Option 1</label></th>

		<td  style="padding:5px;">

			<input type="checkbox" id="_checkbox_1" name="_checkbox_1"   value="<?php echo (isset($_checkbox_1) && $_checkbox_1 != ''  ? 'checked' : ''); ?>"  />

		</td>

	</tr>

	<tr>

		<th style="padding:5px; "><label for="_checkbox_2" style="text-align:left;">Option 2</label></th>

		<td  style="padding:5px;">

			<input type="checkbox" id="_checkbox_2" name="_checkbox_2"   value="<?php echo (isset($_checkbox_2) && $_checkbox_2 != ''  ? 'checked' : ''); ?>"  />

		</td>

	</tr>

</table>

<?

}

save post handler

function save_postmeta($id){

		global $wpdb;

		if (!isset($_SERVER['HTTP_X_REQUESTED_WITH']) ) {

			

			if (isset($_POST['_checkbox_1']) && $_POST['_checkbox_1'] == 'on'){

				delete_post_meta($id, '_checkbox_2');

				if (!update_post_meta($id, '_checkbox_1',  1)){

				    add_post_meta($id, '_checkbox_1',  1, true);

				}		

			} else {

				delete_post_meta($id, '_checkbox_1');

				if (!update_post_meta($id, '_checkbox_2',  1)){

				    add_post_meta($id, '_checkbox_2',  1, true);

				}	

			}

			

		} 

	}

P.S.
Actually for values OR OR better to use radio buttons, not chekboxes

P.P.S
and view



<?php if (get_post_meta($post->ID, '_checkbox_1', true)){ ?>

one checked

<?php } else { ?>

two checked	

<?php }?>

		$options = array(5, 10, 15);

	<label>Price:</label>

	<?php foreach($options as $o): ?>

		<label><?php echo $o ?></label><input name="price[]" type="checkbox" value="<?php echo $o; ?>" <?php if(in_array($o, $price)) echo 'checked="checked"'; ?> />

	<?php endforeach; ?>

<?php

	}



function save_price(){

	global $post;

	update_post_meta($post->ID, "price", serialize($_POST["price"]));

}

?>

This will save all the checkboxes that have been checked.

I think this should do?

<?php

	add_action("admin_init", "admin_init");

	add_action('save_post', 'save_price');



	function admin_init(){

		add_meta_box("prodInfo-meta", "Product Options", "meta_options", "product", "side", "low");

	}



	function meta_options(){

		global $post;

		$custom = get_post_custom($post->ID);

		$price = (bool) $custom["price"][0];

?>

	<label>Price:</label><input name="price" type="checkbox" <?php if ( $price ) {

?>checked="checked"<?php

} ?> />

<?php

	}



function save_price(){

	global $post;

	update_post_meta($post->ID, "price", (bool) $_POST["price"]);

}

?>
