How to change frame to div and load content into div - php

Question

Is there any way to convert an iframe with all attributes it contains into a div or php.
<iframe src='left_nav.php' name='left_nav' class="daemon" scrolling="auto" frameborder='0' height='100%' width="100%"></iframe>
If I use the php include function to call the left_nav.php file:
<?php include left_nav.php; ?>
How to load content which was loading in the frame into the div.
In main.title file (other file)
function toencounter(rawdata) {
document.getElementById('EncounterHistory').selectedIndex=0;
if(rawdata=='') {
return false;
} else if (rawdata=='New Encounter') {
top.window.parent.left_nav.loadFrame2('nen1','RBot','forms/newpatient/new.php? autoloaded=1&calenc=')
return true;
} else if (rawdata=='Past Encounter List') {
top.window.parent.left_nav.loadFrame2('pel1','RBot','patient_file/history/encounters.php')
return true;
}
var parts = rawdata.split("~");
var enc = parts[0];
var datestr = parts[1];
var f = top.window.parent.left_nav.document.forms[0];
frame = 'RBot';
if (!f.cb_bot.checked) {
frame = 'RTop';
}
parent.left_nav.setEncounter(datestr, enc, frame);
top.frames[frame].location.href = '../patient_file/encounter/encounter_top.php?set_encounter=' + enc;
}
In left_nav file
setEncounter(edate, eid, frname) {
if (eid == active_encounter) return;
if (!eid) edate = '<?php xl('None','e'); ?>';
var str = '<b>' + edate + '</b>';
setDivContent('current_encounter', str);
active_encounter = eid;
encounter_locked=isEncounterLocked(active_encounter);
reloadEncounter(frname);
syncRadios();
var encounter_block = $(parent.Title.document.getElementById('current_encounter_block'));
var encounter = $(parent.Title.document.getElementById('current_encounter'));
var estr = ' <b>' + edate + ' (' + eid + ')</b>';
encounter.html( estr );
encounter_block.show();
}
function loadCurrentEncounterFromTitle() {
top.restoreSession();
top.frames[ parent.left_nav.getEncounterTargetFrame('enc') ].location='../patient_file/encounter/encounter_top.php';
}
This is a JS script to loadFrame2
function loadFrame2(fname, frame, url) {
var usage = fname.substring(3);
if (active_pid == 0 && usage > '0') {
alert('<?php xl('You must first select or add a visitor.','e') ?>');
return false;
}
if (active_encounter == 0 && usage > '1') {
alert('<?php xl('You must first select or create an encounter.','e') ?>');
return false;
}
if (encounter_locked && usage > '1') {
alert('<?php echo xls('This encounter is locked. No new forms can be added.') ?>');
return false;
}
var f = document.forms[0];
top.restoreSession();
var i = url.indexOf('{PID}');
if (i >= 0) url = url.substring(0,i) + active_pid + url.substring(i+5);
if(f.sel_frame)
{
var fi = f.sel_frame.selectedIndex;
if (fi == 1) frame = 'RTop'; else if (fi == 2) frame = 'RBot';
}
if (!f.cb_bot.checked) frame = 'RTop';
top.frames[frame].location = '<?php echo "$web_root/interface/" ?>' + url;
if (frame == 'RTop') topName = fname;
return false;
}

Since you want to load content of an other file (left_nav.php) into a div rather than into an iframe, you can use multiple ways to do that.
1) JS:
Create a div container which will hold your content:
<div id="left_nav"></div>
Now, you can use jQuery to load the content easily:
onClick="loadContent('path/to/file/left_nav.php')"
This would be your loadContent function:
function loadContent(path){
$("#left_nav").load(path);
}
2) PHP:
You could also use PHP (pass a parameter to the URL you are currently on yourfile.php?m=left_nav). Then you can include the file, with a controller (MVC principle -> if you want to learn more about it):
<?php
if($_GET["m"] == "left_nav")
include("left_nav.php");
?>
EDIT:
It seems like you need a little mix of both. Instead of your iframe you need to insert a div and load the content at the same time:
<div id="left_nav"><?php include("left_nav.php"); ?></div>
This should be equivalent to creating the iframe. Now, when you change the src of the iframe in your JS scripts, instead of using this line:
top.window.parent.left_nav.loadFrame2('pel1','RBot','patient_file/history/encounters.php');
try changing the content of the div as I stated previously at 1), but you should only need the loadContent function.
