I am almost finished the book, and I am not totally clear on how to use the $page_title variable that appears throughout the book, do we have to include the following code in the title tag of each php script in order to use $page_title. <?php echo $page_title; ?>. In most of the examples in this book the $page_title variable is used in the script without showing the code used in the title tag. Also since the $page_title variable appears below the title tag when I load the php script in my browser I get an error message saying that $page_title isn't a valid variable. Can someone explain to me how to properly use the $page_title variable when writing php scripts. Or is it just easier to write the title in the title tag without using this variable.

Version 0.5 Two questions about page 115. 1. Quoting from the book: "<?php $this->pageTitle = Yii::app()->name . '::' . $model->title; ?>" Why are there two colons before $model->title ? I assume they will appear literally, but maybe they function as code -- I'm not sure. 2. Quoting from the book again: "{TIP} Because the page title is set by assigning a value to the controller instance, it can also be set within the controller action, if you’d rather." This sentence is saying 2 things, neither of which I understand. Larry, can you please break this down and provide an example? Thanks.

I've been trying to get this for a while (includes jQuery) and somehow nothing seems to work. The image gallery works fine but won't display title. $(document).ready(function() { var pics=[]; for (var x=0; x<preLoadPics.lenght;x++) { pics[x]=new Image(); pics[x].src=preLoadPics[x]; } var newPix=new Image(); newPix.src=preLoadPics[0]; $('#thumbPix a').click(function(evt){ evt.preventDefault(); var pixFile=$(this).attr('src'); var pixLink=$(this).attr('href'); var pixTitle=$(this).attr('title'); var oldPix=$('#pix img'); var newPix=$('<img src="'+pixLink+'">'); if(pixLink==oldPix.attr('src')){ return; }else{ $('.selected').removeClass('selected'); //add highlight to this thumbnail $(this).addClass('selected'); //make new image invisible newPix.show(); //add to the #pix div $('#pix').prepend(newPix); newPix.show(); //fade out old image and remove from DOM oldPix.fadeOut(0,function(){ $(this).remove(); }); //fade in new image newPix.fadeIn(0); oldPix.remove(pixFile,'^Lg+\w\.'); } }); //end click $('#thumbPix a:eq(0)').click(); }); //end ready </script> this is body section <div id="thumbPix"> <li><a href="LgPicture.jpg" id="pix"title="Picture"> <img src= "smallPicture.jpg" border="2" bordercolor="#cccc99"/>Picture<br /></a></li> One option that doesn't break it completely is adding pixTitle to the .prepend in the Javascript code. I got it to display title, but then it just builds the titles instead of replacing it. $('#pix').prepend(newPix,pixTitle); newPix.show(); any ideas? Thanks
