This is JavaScript code used with the jQuery framework so that when a user highlights a section of text on the page that you store what they highlighted. The jQuery code is below and the PHP is below that. Simple.
/* attempt to find a text selection */
function getSelected()
{
if(window.getSelection)
{
return window.getSelection();
}
else if(document.getSelection)
{
return document.getSelection();
}
else
{
var selection = document.selection && document.selection.createRange();
if(selection.text)
{
return selection.text;
}
return false;
}
return false;
}
/* create sniffer */
$(document).ready(function() {
$('#content-area').mouseup(function(){
var selection = getSelected();
if(selection && (selection = new String(selection).replace(/^\s+|\s+$/g,'')))
{
$.ajax({
type: 'post',
url: 'ajax-selection-copy.php',
data: 'selection=' + encodeURI(selection)
});
}
});
});
if(!empty($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest' && $selection = trim($_POST['selection']))
{
mysql_query('INSERT INTO text_selections (selection,date_selected) VALUES(\''.mysql_escape_string(stripslashes($selection)).'\',NOW())');
}
