Incredibly Simple Tabs with jQuery

Whenever I need inline tabs, I find myself traveling down the same well trod paths. There are dozens of plugins but where they usually fail is in simplifying skinning. Solution:

1. Create each tab row as a graphic (so all tabs but the selected one in a row would look the same
2. Add images to page surrounding each as a DIV
3. Add a bit of jQuery to hide show appropriate tab & content on click

Here's the CSS:

 
<div id="tabs">
<div id="speakers"><img src="img/tabs-speakers.gif" width="724" height="41" alt="Speakers" /></div>
<div id="events"><img src="img/tabs-events.gif" width="724" height="41" alt="Speakers" /></div>
<div id="tabs-content">
<div id="speakers-content" class="tab-content">
 
Content for speakers
</div>
<div id="events-content" class="tab-content">
 
Content for events
</div>
</div>
</div>
 

Next, add the javascript:

var tabArray=new Array("speakers","events");
$(document).ready(function() {
   $('#events').hide();
   $('#events-content').hide();
   $('#tabs').click(function() {
	   $.each(tabArray, function(index, value) {
		   $('#'+value).toggle();
		   $('#'+value+'-content').toggle();
	   });
   });
});

Passing Arrays to PHP via AJAX

I've written on processing AJAX queries before but neglected discussing how to pass an array to PHP for processing. This is an example of getting all checked rows in an EXTJS grid and posting them to an awaiting PHP script.

First we have the users confirm they really want to process all checked records:

 
Ext.MessageBox.confirm('Confirm', 'Are you sure your want to email login info to all selected users?', confirmEmailUsers);
 

Now the jQuery method:

 
function confirmEmailUsers(btn){
   if(btn=='yes'){
	   var recArray=new Array();
	   var ids=new Array();
	   var recArray = mailqueueGrid.getSelectionModel().getSelections();
	   for (var i = 0 ; i < recArray.length ;i++) {
		  ids[i] = recArray[i].get('id');
	   }
	  $.ajax({
		type: "POST",
		dataType: 'json',
		url: '/cpsia/?c=form&m=processqueue',
		data: 'ids='+ids,
		success: function(msg){
			alert(msg)
		}
	  });
   }
}
 

Finally, the PHP script to processes it:

 
$ids = explode(",",$_POST['ids']);
foreach ($ids as $id) {
   echo $id .'';
}
