I'm building a site which allows users to create an html page which can then be saved and shared on another site. I want them to be able to resize and drag the page elements. I can do this using jQuery, but I'm not sure how I then save that so that when the page is viewed elsewhere, it looks the same.
I haven't decided yet how to store the page info, but what I'm thinking is that I can store each element in the database along with its absolute position, and its contents. Does that sound like a good plan?
If so, how do I get the position for the div to pass to the php so that it can be saved?
Thanks.
JQueryUI Resizable has an event called resize
that you can use:
var resposition = '';
$('#divresize').resizable({
//options...
resize: function(event,ui){
resposition = ui.position;
}
});
The same occurs with JQueryUI Draggable and its event drag
:
var dragposition = '';
$('#divdrag').draggable({
// other options...
drag: function(event,ui){
dragposition = ui.position;
}
});
resposition
and dragposition
is going to be arrays. You can see it working here: http://jsbin.com/uvuzi5
EDIT: using a form, you can save dragposition
and resposition
into hidden inputs
var inputres = '<input type="hidden" id="resposition" value="'+resposition.left+','+resposition.top+'"/>'
$('#myform').append(inputres);
var inputdrag = '<input type="hidden" id="dragposition" value="'+dragposition.left+','+dragposition.top+'"/>'
$('#myform').append(inputdrag);
And in your PHP file to handle the form:
$dragposition = $_GET['dragposition'];
$resposition = $_GET['resposition'];
$dragposition = explode(',',$dragposition);
$resposition = explode(',',$resposition);
Finally, both variables should be arrays with top and left attributes:
$dragposition => [top,left] attributes from draggable
$resposition => [top,left] attributes from resizable
you have to save position at some where so that you can get position
details when next time you open page.
option 1: you can store html elements position details in "localStorage" its default browser storage.
Example: Demo
<!DOCTYPE html>
<html lang="en">
<head>
<title>Dashboard</title>
<!-- jQuery -->
<script src="vendor/jquery/jquery.min.js"></script>
<link rel="stylesheet" type="text/css" href="dist/css/jquery-ui.min.css">
<script src="dist/js/jquery-ui.min.js"></script>
</head>
<body>
<script>
var positions = JSON.parse(localStorage.positions || "{}");
$(function() {
var d = $("[id=draggable]").attr("id", function(i) {
return "draggable_" + i
})
$.each(positions, function(id, pos) {
$("#" + id).css(pos)
})
d.draggable({
containment: "#wrapper",
scroll: false,
stop: function(event, ui) {
positions[this.id] = ui.position
localStorage.positions = JSON.stringify(positions)
}
});
});
</script>
<div id="wrapper">
<div id="draggable" class="ui-widget-content draggable" style="height:100px;width:100px;float:left">Div1</div>
<div id="draggable" class="ui-widget-content draggable" style="height:100px;width:100px;float:left">Div2</div>
<div id="draggable" class="ui-widget-content draggable" style="height:100px;width:100px;float:left">Div3</div>
</div>
</body>
</html>
option 2: you can store html elements position details in "your database"
