sort a array by its value

by Adrian on Jul.29, 2010, under Programming, Work

To sort an array by its value, similiar to mysql sort by just use

Code:



usort($array, create_function('$a, $b, $sortBy="distance"', 'return strnatcmp($a[$sortBy], $b[$sortBy]);'));

$array stores the array
$sortBy set the key to sort by

i.e

Code:



$array = array (
    1=>array('name'=>'me','location'=>'somewhere','distance'=>'200'),
    2=>array('name'=>'you','location'=>'somewhere','distance'=>'2')
    );

usort($array, create_function('$a, $b, $sortBy="distance"', 'return strnatcmp($a[$sortBy], $b[$sortBy]);'));
print_r($array);

will result in the array being re-ordered with location 2 now being in location 1 (preserving the keys)

styling form buttons with divs

by Adrian on Aug.28, 2009, under Programming

Styling a button inside a form with multiple div`s to achieve a curved button with click events etc, can be done relatively easy with the use of javascript.

For example:

firstly lets take a look at our raw code

<form method="post" action="">
      <input type="submit" name="submit">
</form>

Next we place the button within no script tags, so it only displays if javascript is switched off, so that
non javascript enabled browsers can still submit.

<form method="post" action="">
      <noscript>
          <input type="submit" name="submit">
      </noscript>
</form>

Now we add the javascript styled button

 
<form method="post" action="" name="mainForm">
      <noscript>
          <input type="submit" name="submit">
      </noscript>
	<script type="text/javascript">
	<!--					
 
	// do the submission
	function submitform(){
		document.mainForm.submit();
		}
 
	// print the button
	document.write('<a href="javascript:submitform();" style="text-decoration:none; color:#fff; font-weight:bold;">');
 
	document.write('<div id="buyButtonMid">');
	document.write('<div id="buyButtonLeft"></div>');
	document.write('submit');
	document.write('<div id="buyButtonRight"></div>');
	document.write('</div>');
 
	document.write('</a>');
 
 
	// -->
 
	</script>
</form>

Then style your button accordingly with your css,

/* buy button */
#buyButtonRight{
	width:16px;
	height:44px;
	display:block;
	position:absolute;
	top:0;
	right:0;
	cursor:pointer;
	}
 
#buyButtonLeft{
	width:16px;
	height:44px;
	display:block;
	position:absolute;
	top:0;
	left:0;
	cursor:pointer;
	}
 
#buyButtonMid{
	height:24px;
	min-width:20px;
	/*max-width:300px;*/
	padding:13px 20px 7px 20px;
	display:block;
	position:relative;
	float:left;
	cursor:pointer;
	color:#ffffff; 
	font-size:13px; 
	text-decoration:none;
	}
 
 
/* normal */
#buyButtonLeft{background:url('images/add2bas_left.jpg');}	
#buyButtonMid{background:url('images/add2bas_mid.jpg');}	
#buyButtonRight{background:url('images/add2bas_right.jpg');}
 
/* hover */
#buyButtonMid:hover #buyButtonLeft{background:url('images/add2bas_left_hover.jpg');}
#buyButtonMid:hover {background:url('images/add2bas_mid_hover.jpg');}
#buyButtonMid:hover #buyButtonRight{background:url('images/add2bas_right_hover.jpg');}
 
/* click */
#buyButtonMid:active #buyButtonLeft{background:url('images/add2bas_left_click.jpg') no-repeat;}
#buyButtonMid:active {background:url('images/add2bas_mid_click.jpg');}
#buyButtonMid:active #buyButtonRight{background:url('images/add2bas_right_click.jpg');}

wordpress comment count as a button

by Adrian on Jul.30, 2009, under Programming, Work, wordpress

Styling the wordpress comment count as a button/icon etc can be tricky because the normal call to the comments

1	comments_popup_link(__('Comments (0)'), __('Comments (1)'), __('Comments (%)'));

formats the output as an anchor point with the correct link, alt tags etc already set up.

So in order to intercept this and then add you own anchor point with divs/imagery etc you need to make a custom request

 
// SQL
$SQL = "SELECT COUNT(*) AS Count FROM $wpdb->comments WHERE comment_approved='1'";
$SQL.= "AND comment_post_ID='".intval($post->ID)."'";
 
// Sort the array into a string prefixed with 'Comments '
list($comments) = $wpdb->get_results($SQL, ARRAY_A); 	
$comments='Comments ('.$comments['Count'].')';
 
// generate the alt and title tags
$alt = 'Comment on '.$post->post_title;
 
// echo the button if this is not a single and not a page
if (!is_single() && !is_page()) {
 
// anchor open
echo '<a href="'.get_permalink($post->ID).'" alt="'.$alt.'" title="'.$alt.'">';
 
// complex formatting rules for the comment pop up, go here
echo $comments;
 
// anchor close
echo '</a>';
}
