I have been following a tutorial on creating a style switcher with PHP and jQuery, now in the tutorial the PHP function uses get data, which is not available in codeigniter, I was hoping someone would be able to help me tidy up my sorry attempt?
My PHP function
function setBackground() {
$style = $this->uri->segment(3);
setcookie("style", $style, time() + (60*60*24*30));
echo $style;
}
My HTML and jquery call
<ul id="options">
<li><a class="option" href="<?php echo base_url();?>welcome/setBackground/red">Red</a></li>
<li><a class="option" href="<?php echo base_url();?>welcome/setBackground/green">Green</a></li>
</ul>
<script type="text/javascript">
$('a.option').styleSwitcher(); // calling the plugin
</script>
The jQuery plugin
jQuery.fn.styleSwitcher = function(){
$(this).click(function(){
loadStyleSheet(this);
return false;
});
function loadStyleSheet(obj) {
$('body').append('<div id="overlay" />');
$('body').css({height:'100%'});
$('#overlay')
.css({
display: 'none',
position: 'absolute',
top:0,
left: 0,
width: '100%',
height: '100%',
zIndex: 1000,
background: 'black url(img/loading.gif) no-repeat center'
})
.fadeIn(500,function(){
$.get( obj.href+'&js',function(data){
$('#stylesheet').attr('href','/media/css/' + data + '.css');
cssDummy.check(function(){
$('#overlay').fadeOut(500,function(){
$(this).remove();
});
});
});
});
}
var cssDummy = {
init: function(){
$('<div id="dummy-element" style="display:none" />').appendTo('body');
},
check: function(callback) {
if ($('#dummy-element').width()==2) callback();
else setTimeout(function(){cssDummy.check(callback)}, 200);
}
}
cssDummy.init();
}
On clicking the link to change the stylesheet I get this error rturned via firebug,
An Error Was Encountered
The URI you submitted has disallowed characters.
the URL that is being sent is,
http://mywebsite/index.php/welcome/setBackground/green&js
this example is me clicking the green choice.
