All is working quite well, except one thing:
when I select the news to edit, the content is from the server is correcly posted on the php, but on the HTML the scripts in the php (CKEDITOR and Char Cunter) are not active.
So, on my HTML, were the user will edit the news, i get only a simple textarea instead of the CKEDITOR, etc.
Is there a way to fix that? Can you help me somehow?
Thank you!
EDIT: I solved by myselft the problem. See solution as answer.
For those who have the same question:
I solved my problem in the following way: on javascript add a new row:
document.getElementById("newsdamodificare").action=CKEDITOR.replace('modificatesto');
between this 2 lines:
document.getElementById("newsdamodificare").innerHTML=xmlhttp.responseText;
NEW LINE TO INSERT HERE
}
And remove from the php these rows:
<script>
CKEDITOR.replace('modificatesto');
</script>
Hope this helps!
You're trying to select your textarea by it's name, but CKEDITOR.replace('modificatesto'); is looking for an ID.
Try
<textarea id="modificatesto"><?php echo $body ?></textarea>
<script>
CKEDITOR.replace('modificatesto');
</script>

I hope today I'll find good solution for my case below.

Actually, I have dynamic input fields and let say there field A, B and C. So, the purpose is when field A receives OnKeyUp Action then field B and C will autofill based query result from field A value.

Above code already success for row 1. but when I input value in row 2 (dynamic add new row) the result change field B and C in row 1 not in row 2.
I have an an ajax drop down box that if selected adds another field to a form, this works but this new field doesn't get submitted with the form. Any suggestions?

This now shows n/a but not the value of newWork1
You have very modified the original question, I can only respond to what was previously.
The important part is also findTest.php
from this script you replace your
document.getElementById('workdiv').innerHTML=req.responseText;
So how does findTest.php know about $_POST['newwork1']
<td>New work1<input name="newWork1" ... value="<?=$_POST['newwork1']?>" /></td>..
This must come via a GET / POST, but in your GET there ist only
strURL="findTest.php?work="+workId;
Only 1 GET variable named $_GET['work'].
and you use this variable (without test)
$work=$_GET['work'];
And then you mixed the request from $_GET to $_POST['newwork1']
so why not use your select value to get it all together.
Test.php
...
<select name="WorkDone" tabindex="14" onchange="getWorkDone(this.value)">
<option value="Work1">Work1</option>
<option value="Work2">Work2</option>
<option value="Noworktoday">No work today</option>
<option value="Other">Other</option>
</select>
...
findTest.php
if (isset($_GET['work'])) {
//for example : $work == "Work1"
$work=$_GET['work'];
if ($work=="Noworktoday") {
echo "<tr><td>No work today</td></tr>";
} else {
echo "<tr><td>New ".$work."<br>";
echo "<input name=\"new".$work."\" type=\"text\"";
echo " size=\"20\" value=\"new".$work."\" />";
echo "</td></tr>";
}
//<tr><td>New Work1<input name="newWork1" type="text" size="20" value="newWork1" /></td></tr>
Update:
You can not see your values because you did'nt echo them
and you have to test all $_POST
$page = '';
$answer = null; //clean start.
if (isset($_POST['Comments'])) {
$Comments = $_POST['Comments']; } else {
$Comments = 'n/a';
}
if (isset($_POST['newWork1'])) {
$newWork1 = $_POST['newWork1']; } else {
$newWork1 = 'n/a';
}
....
and so on for all possible values
echo your variables
if (isset($_POST['Submit'])) {
?>
<p align="center" id="infomessage">Test message = <? echo $Comments; ?>
and = <? echo $newWork1; ?> or this should be
work2 = <? echo $newWork; ?></p>
<? } ?>
Update:
I can not see the actual code, you need a if (isset ... for all possible variables . In my example I have described only two possibilities. You need also e.g.
if (isset($_POST['newWork2'])) { ...
if (isset($_POST['newOther'])) { ...
and so on !! And make only asimple output.
if (isset($_POST['Submit'])) {
echo "message = ".$Comments."<br>";
echo "newWork1 = ".$newWork1."<br>";
echo "newWork2 = ".$newWork2."<br>";
echo "newOther = ".$newOther."<br>";
}
and put it logical together
This is illogical Work2 assigned to newWork !!!

My problem now is that everything works fine in chrome and IE but the form is not submitted when i click the submit button in firefox. I am using firefox 20.0.1. Update: I have removed the html,head and body tags from send_req.php
still not working
form is not allowed inside table. Please see also
Form inside a table

Michael
Reminder : the structure of an HTML document is :
<!-- No div before html tag -->
<!DOCTYPE html> <!-- Doctype for HTML5 ; use whatever doctype you need -->
<html>
<head>
</head>
<!-- No div before body tag -->
<body>
<!-- Divs only belongs here -->
</body>
</html>
<!-- No div after html tag -->
If you don't follow this basic structure, you're forcing the browser to interpret your invalid code (+ quirks mode when you don't provide a doctype).
Some browser guess well what you tried to do, others don't, as Firefox might.
Please use a HTML validator as W3's validator to check your syntax.
I have a drop down menu of mobile brands. When a user selects a mobile brand a dynamic drop populates with the mobile model according to the mobile brand I want to validate that mobile model drop down for a blank select value. I am using ajax xmlhttp request for getting the mobile model drop down menu.

</form>
and the code of getuser.php is
<table>
<tr>
<td>Mobile Model</td>
<td>
<?php
$q=$_GET["q"];
include("admin/config.php");
echo "<select name='step3_mobilemodel' id='step3_mobilemodel' ><option value=''>Select Mobile Model</option>";
$result = mysql_query ("select * from mobilemodel where brandcode='".$q."'");
while ($adcom=mysql_fetch_array($result)) {
echo "<option value=\"".$adcom['mobilemodel']."\">".htmlspecialchars($adcom['mobilemodel'])."</option>";
}
echo "</select>"; ?>
</td>
</tr>
</table>
The Output am getting is correct i just want to validate the mobile model drop down menu for blank select
For validating select you can do:
var e = document.getElementById("step3_mobilemodel");
var mobileVal = e.options[e.selectedIndex].value;
if(mobileVal == "") {
...//show your error here
}
Hope it helps
This is pretty much what Sudhir posted (+1 from me) but with an example in a fiddle: http://jsfiddle.net/5TYwH/1/ using the onchange event handler.
May be you can just add a php validation for $q.
<table>
<tr>
<td>Mobile Model</td>
<td>
<?php
$q=$_GET["q"];
echo "<select name='step3_mobilemodel' id='step3_mobilemodel'>"
if($q != ""){
include("admin/config.php");
echo "<option value=''>Select Mobile Model</option>";
$result = mysql_query ("select * from mobilemodel where brandcode='".$q."'");
while ($adcom=mysql_fetch_array($result)) {
echo "<option value=\"".$adcom['mobilemodel']."\">".htmlspecialchars($adcom['mobilemodel'])."</option>";
}}else{ echo "<option value=''>Please select a mobile first</option>";} echo "</select>";?></td>
</tr></table>
I have a dropdown list for items. What I want to do is get the item quantity, remaining quantity and dispatched item values which depends on the value in the drop down.
I have this code :
<form method="post" action="restore_stocks.php">
<table>
<tr>
<td>Item Name:</td>
<td><select name="itemname">
<?php
$item="SELECT item_name FROM stocks";
$itemresult = #mysql_query($item)or die ("Error in query: $query. " . mysql_error());
while($row=#mysql_fetch_array($itemresult)){
echo "<OPTION VALUE=".$row['item_name'].">".$row['item_name']."</option>";
}
?>
</select></td></tr>
<tr>
<td>Item Quantity:</td>
<td><?php
$row = mysql_fetch_object($itemresult);
echo $row->item_quantity; ?></td></tr>
<tr>
<td>Remaining Quantity:</td>
<td><?php echo $row->rem_quantity; ?></td></tr>
<tr>
<td>Stocks Dispatched:</td>
<td><?php echo $row->stocks_dispatched; ?></td></tr>
<tr>
<td>Add Stocks:</td>
<td><input name="addstocks" type="text" size="25" maxlength="25" /></td></tr>
<tr>
<td> </td>
<td><input type="submit" name="Submit" id="Submit" value="Restore" /></td>
</tr>
</table>
</form>
I really don't know how to start the code because i'm new to this approach. If you can help me it's much appreciated. Thanks in advance.
This works: The jist is that the page uses ajax to call a script, which will deliver XML of the values you need, and will then populate those fields accordingly. :
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
</head>
<body>
<script>
function updateFields(itemname){
var xmlhttp;
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
var xmlDoc=xmlhttp.responseXML;
var iQdata=xmlDoc.documentElement.getElementsByTagName("ITEMQUANTITY");
var rQdata=xmlDoc.documentElement.getElementsByTagName("REMAININGQUANTITY");
var sDdata=xmlDoc.documentElement.getElementsByTagName("STOCKSDISPATCHED");
var iQ=iQdata[0].firstChild.nodeValue;
var rQ=rQdata[0].firstChild.nodeValue;
var sD=sDdata[0].firstChild.nodeValue;
document.getElementById("itemQuantity").innerHTML=iQ;
document.getElementById("remainingQuantity").innerHTML=rQ;
document.getElementById("stocksDispatched").innerHTML=sD;
}
}
xmlhttp.open("GET","quantity_script.php?itemname="+itemname,true);
xmlhttp.send();
}
</script>
<form method="post" action="restore_stocks.php">
<table>
<tr>
<td>Item Name:</td>
<td><select name="itemname" onchange="updateFields(this.value)">
<?php
$item="SELECT item_name FROM stocks";
$itemresult = #mysql_query($item)or die ("Error in query: $query. " .mysql_error());
while($row=#mysql_fetch_array($itemresult)){
echo "<OPTION VALUE=".$row['item_name'].">".$row['item_name']."</option>";
}
?>
</select></td></tr>
<tr>
<td>Item Quantity:</td>
<td><div id="itemQuantity"></div></td></tr>
<tr>
<td>Remaining Quantity:</td>
<td><div id="remainingQuantity"></div></td></tr>
<tr>
<td>Stocks Dispatched:</td>
<td><div id="stocksDispatched"></div></td></tr>
<tr>
<td>Add Stocks:</td>
<td><input name="addstocks" type="text" size="25" maxlength="25" /></td></tr>
<tr>
<td> </td>
<td><input type="submit" name="Submit" id="Submit" value="Restore" /></td>
</tr>
</table>
</form>
</body>
</html>
And then you'd also make a script on your site "quantity_script.php" that would be something like the following:
<?php
//include your DB connection info
$itemname=mysql_real_escape_string($_POST["itemname"]);
$item="SELECT ".$itemname." FROM stocks";
$itemresult = mysql_query($item);
$row=mysql_fetch_assoc($itemresult);
header('Content-type: text/xml');
echo "<ROOT>";
echo "<ITEMQUANTITY>".$row["item_quantity"]."</ITEMQUANTITY>";
echo "<REMAININGQUANTITY>".$row["rem_quantity"]."</REMAININGQUANTITY>";
echo "<STOCKSDISPATCHED>".$row["stocks_dispatched"]."</STOCKSDISPATCHED>";
echo "</ROOT>";
?>
