What I am wanting to do is when a username is taken from the handler function and taken to the edithandler function and then that username is taken to the DB as well and grabs all of that username's database info from all the fields and filled in on the form that resides in the edithandler function. Included down blow is my functions and this is also what I was told to do. Is this correct?
1) I dont think you can access browser sessions from a php script called with ajax.
2) You should send the username as another GET variable within the javascript like this:
url = 'backstagefunctions.php?f=' + url + '&u=' + <?= $_SESSION['username']; ?>
This is assuming the javascript is within a php file that has sessions enabled before it reaches the <head> tags of the html.
3) In the "edithandler" function change ( within the mysql query ) $_SESSION['username'] to $_GET['username']
Remember a function called with AJAX returns a string only sent using echo or print. You then must break that string down withhin the javascript. So for example, if your php gets the users details you may have it generate and return a string like this $output = 'usernamehere&agehere&firstnamehere'; echo $output;
Then in the javascript you can get each variable like this:
var response = ajaxobect.responseText;
response = response.split ( '&' );
var username = response[0];
var age = response[1];
var firstname = response[2];
Then fill your form fields in a way like this;
document.formname.fieldname.value = variable;
Is all of that right? Just trying to get a second opinion.
Along included is also my ajax.js file
Code:
var loadedobjects=""
var rootdomain="http://"+window.location.hostname
function ajaxpage(url, containerid)
{
url = 'backstagefunctions.php?f=' + url;
var page_request = false
if (window.XMLHttpRequest) // if Mozilla, Safari etc
page_request = new XMLHttpRequest()
else if (window.ActiveXObject)
{
// if IE
try
{
page_request = new ActiveXObject("Msxml2.XMLHTTP")
}
catch (e)
{
try
{
page_request = new ActiveXObject("Microsoft.XMLHTTP")
}
catch (e)
{
}
}
}
else
{
return false
}
page_request.onreadystatechange=function()
{
loadpage(page_request, containerid)
}
page_request.open('GET', url, true)
page_request.send(null)
}
function loadpage(page_request, containerid)
{
if (page_request.readyState == 4 && (page_request.status==200 || window.location.href.indexOf("http")==-1))
document.getElementById(containerid).innerHTML=page_request.responseText
}
function loadobjs()
{
if (!document.getElementById)
return
for (i=0; i<arguments.length; i++)
{
var file=arguments[i]
var fileref=""
if (loadedobjects.indexOf(file)==-1)
{
//Check to see if this object has not already been added to page before proceeding
if (file.indexOf(".js")!=-1)
{
//If object is a js file
fileref=document.createElement('script')
fileref.setAttribute("type","text/javascript");
fileref.setAttribute("src", file);
}
else if (file.indexOf(".css")!=-1)
{
//If object is a css file
fileref=document.createElement("link")
fileref.setAttribute("rel", "stylesheet");
fileref.setAttribute("type", "text/css");
fileref.setAttribute("href", file);
}
}
if (fileref!="")
{
document.getElementsByTagName("head").item(0).appendChild(fileref)
loadedobjects+=file+" " //Remember this object as being already added to page
}
}
}
function WrestlerList()
{
var addWrestler = document.getElementById("character_selection").value
if (addWrestler) {
// Here we append a new wrestler to your hidden field using a comma
document.getElementById("chars").value += addWrestler+",";
// Continue your original functionality
document.getElementById("characterlist").innerHTML += "<li>" +
addWrestler + "</li>";
return WrestlerList;
}
}
