i have form which genrate from a specific search button.the newly generated form has several form wich can update it's own data
how to doing such a update without any affect to current page.
because of search result and search parameter should not be change.
eventually question in sort, give me an idea to "update each record based on query search while displaying it'.
ex:
<pre>
**name:[** k% **] branch:[** acc **] SEARCH** >>>>search form
EMPID | NAME | BRANCH | EDIT |
1 | kamal | acc | edit | >>>>>>dynamicaly generated form based query serch
2 | kapila | acc | edit | >>>>>>dynamicaly generated form based query serch
</pre>
thank you..
here my try

I like to post the information back to the same page. You can use php to handle the post at the start of the script and then you already have all the data you submitted so you can populate the search field and everything using that data.
Alternatively don't submit the form but perform an ajax query. That way your current page remains unchanged.

I am supposed to have my form elements repopulate using php and html only after I click the link from page two. However, none of the fields are repopulating. Please help me!!?
Page 1:
<?php

<?php
/*
This page should:
1) Use a cookie (NOT PHP SESSION) that expires a year from now to do the following:
Record the timestamp of the FIRST load of this page (but NOT any subsequent load of this page).
Note: You only need first 3 parameters in setcookie() for this HW.
2) If the suvey was already completed, transfer to third page (thank you page).
That page instructs you to set a cookie that will allow you to detect this.
Recall from the CRUD example how page transfers are done in PHP:
header("Location: URL");
3) The form in this page should submit to THIS PAGE, and then transfer to hw_page2.php
after saving stuff to PHPs built-in $_SESSION superglobal.
The data will then be available in all the other pages (remember no database is allowed for this HW).
4) If the button in the 2nd page is clicked to come back to this page, the
Session data should re-populate into the form.

Please help me figure out where I am making a mistake! I have been working on it for days but I cannot figure out the answer.
I built a search form for an app and it is currently only pulling back on result at a time where there should be multiples. I am sure this is something dumb and was wondering if someone can tell me what I am doing wrong.
Here is the full code:
<?php
// php search data in mysql database using PDO
// set data in input text
$TaskId = "";
$ClientId="";
$TaskName = "";
$TaskDescription = "";
$TaskStartAt = "";
if(isset($_POST['Find']))
{
// connect to mysql
try {
$pdoConnect = new PDO("mysql:host=localhost;dbname=tt","root","root");
} catch (PDOException $exc) {
echo $exc->getMessage();
exit();
}
// id to search
//$TaskId = $_POST['TaskId'];
$ClientId = $_POST['ClientId'];
// date to search
//$DateCreated = $_POST['DateCreated'];
// mysql search query
$pdoQuery = "SELECT *
FROM tasks t
left join users u using (UserId)
left join clients cl using (ClientId)
WHERE t.isdeleted = 0 and ClientId = :ClientId";
$pdoResult = $pdoConnect->prepare($pdoQuery);
//set your id to the query id
$pdoExec = $pdoResult->execute(array(":ClientId"=>$ClientId));
if($pdoExec)
{
// if id exist
// show data in inputs
if($pdoResult->rowCount()>0)
{
echo '<table>';
foreach
($pdoResult as $rows)
{
//$TaskId = $row['TaskId'];
$ClientId = $rows['ClientId'];
// $TaskName = $row['TaskName'];
// $TaskDescription = $row['TaskDescription'];
}
echo '</table>';
}
// if the id not exist
// show a message and clear inputs
}else{
echo 'ERROR Data Not Inserted';
}

At a quick glance, it seems to be simply that you’ve split your functionalities up too much.
At the top of the page, you establish your database connection and retrieve the result set. Then you echo a table element, foreach through the PDO Statement object and assign the contents of the current row to the variable $rows. Note: the content of the current row.
Further down on the page, you echo the individual fields, using $rows['field']—but you do this outside your foreach loop. Since $rows gets repopulated everytime the loop loops around, and since you don’t destroy the variable after the loop completes, you end up at the end with a variable that still contains the last row from your result set.
You need to put the place where you actually print the contents of each individual row inside the loop that iterates through your statement object to retrieve the fields. On the other hand, you only want to do this at all if any user input has been entered at all, so the whole thing still needs to be inside the positive branch of the very first condition that checks if $_POST['Find'] is set, like in the version below.
I start out here by assigning a variable $results to be an empty string—that’s the value we’ll output if the user hasn’t sent the form at all. If $_POST['Find'] is not empty, then we search the database, iterate through the result set, create an HTML string in this loop, and store the result in the $results variable. If no rows are returned or the execute() call fails entirely, we throw an exception to be handled by an exception handler (that you will have to define at a central level, for your entire project), passing along a generic error message to be displayed to the user.
Note that I’ve also stripped out a lot of extraneous stuff and comments to make the relevant bits clearer and renamed the $rows variable to $row to make it clear that since it’s populated inside a loop, it contains one row, not all of them.
<?php
// Set the global exception handler—should of course be done
// in a global boilerplate file, rather than for each file
set_exception_handler('your_exception_handler_here');
$results = "";
if(!empty($_POST['Find']))
{
$pdoConnect = new PDO("mysql:host=localhost;dbname=tt","root","root");
$pdoConnect->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
$ClientId = $_POST['ClientId'];
$pdoQuery = "SELECT *
FROM tasks t
left join users u using (UserId)
left join clients cl using (ClientId)
WHERE t.isdeleted = 0 and ClientId = :ClientId";
$pdoResult = $pdoConnect->prepare($pdoQuery);
$pdoExec = $pdoResult->execute(array(":ClientId"=>$ClientId));
if($pdoResult->rowCount()>0)
{
$results = '<table border="0">
<tr COLSPAN=2 BGCOLOR="lightblue">
<td>Id</td>
<td>Client</td>
<td>Task Name</td>
<td>Task Description</td>
<td>Hours</td>
<td>Date Created</td>
<td>Who Completed Task</td>

foreach ($pdoResult as $row)
{
$ClientId = $row['ClientId'];
$results .= "<tr>".

hey guys i've passed way more time on this then what i originally wanted to...
so i have this code here, where i have a drop list give me data from a sql database from the selection of 3 radio buttons, that all works fine.
My problem come when i want to submit my form and get info of the data in said droplist. all i want is put the selected radio and the selected item in the single drop list in variables in the submission.php that comes after the post method of the form...
anyway thats what i want to do for now

all i seem to be able to get is the radio button choice.
Here is an all-in-one solution. You need to change some references like what the name/local path of the file path is, but anyway, this contains all the code. I can not test the DB stuff but the ajax works if you have the correct url path in the jQuery portion. Note, this solution references itself, not a new page:
// Display errors for troubleshooting
ini_set('display_errors','1');
error_reporting(E_ALL);
class CategorySelector
{
public function LoadSubCat()
{
// You will be subjected to an injection hack if you don't filter or encode this variable
// You should do PDO with prepared statements
$parent_cat = htmlspecialchars($_GET['parent_cat'], ENT_QUOTES);
$query = $this->Fetch("SELECT id,subcategory_name FROM subcategories WHERE categoryID = '$parent_cat'");
// Uncomment this to see how this returns
// $this->PrintPre($query); ?>
<label for="sub_cat">Sub Category</label>
<select name="sub_cat" id="sub_cat">
<?php
if($query !== 0) {
foreach($query as $row) { ?>
<option value="<?php echo $row['id']; ?>"><?php echo $row['subcategory_name']; ?></option>
<?php
}
} ?>
</select>
<?php
}
public function Form()
{
// Get rows for categories
$results = $this->Fetch("SELECT id,category_name FROM categories");
// Uncomment this to see how this returns
// $this->PrintPre($results); ?>
<form name="form1" id="form1" method="post">
<label for="parent_cat">Parent Category</label>
<select name="parent_cat" id="parent_cat">
<?php
if($results !== 0) {
foreach($results as $row) { ?>
<option value="<?php echo $row['id']; ?>"><?php echo $row['category_name']; ?></option>
<?php }
} ?>
</select>
<!-- This is a container that will load in your next menu -->
<div id="sub_cat_container"></div>
<input type="submit" name="submit" value="submit" />
</form>
<?php
}
public $rowCount;
// This is strictly a returning engine for SQL statements
protected function Fetch($_sql)
{
include_once('config.php');
// You really should do prepared statements (PDO)
// This way of calling sql is depricated
$query = mysql_query($_sql);
// Save the row count
$this->rowCount = mysql_num_rows($query);
// If there are rows return them
if($this->rowCount > 0) {
$_array = array();
// Loop through
while($result = mysql_fetch_array($query)) {

Quote all your HTML attributes like name='Subcategory', and
echo "<option value=$row[cat_id]>$row[Subcategory]</option>"
should be
echo "<option value='{$row['cat_id']}'>{$row['Subcategory']}</option>";
Your coding practice is horrible, by the way. You are not testing to see how many rows you have in your MySQL query, and you don't need to echo on each line. You can do this:
echo '<br />'.
'<br />';
Of course, using line breaks like that is a bad practice, as well. Use CSS.
Im new to Jquery and trying to recreate something muddled together a while ago, with a similar function.
i have pasted my code here: http://pastebin.com/SYM45WPw
I have a table which is created base on results of a form on the previous page (this is all working ok) with Student names in the first column, then every column after that has will be a result for testing requirement, simply a drop down with Pass / Fail, and for each person and each requirement i want to go along and pick the result, and submit the results to DB in thhe back ground and then removed the Select option and displays the result.
Currently on the post_result.php i have this, just to text i am getting a result:
if($_POST['studentID'] != ""){
echo "Success";
}
All help is much appreciated,
Edit: (taken from pastebin link)
<?php
ini_set('error_reporting', E_ALL);
$student_name = $_POST['student_name'];
$class = $_POST['class'];
$month = $_POST['month'];
?>

You're serializing a Select element, not the form, and you must serialize the form.
For example:
<form id="myForm" action="blabla" method="blabla">
<select id="result" name="result">
<option>Bla Bla Bla</option>
</select>
<input type="text" name="student_name" />
<!-- ...more elements .... -->
</form>
So you have to replace:
var result = $(this).serialize()
//by:
var result = $("#myForm").serialize()
In the file you are sending data to via Ajax you have 'studentID' as your key but in the form you are serializing, the keys are assigned from the name='' attribute. That would make your keys: 'student_name' and 'result'.
if($_POST['studentID'] != ""){
echo "Success";
}
One way you could make sure of this is by placing the following into the php file your Ajax is sending and receiving. This will print an array of the post content being received by your php file.
print_r($_POST);
The results form that array will show up in the div where you are telling Ajax to place the results.
This is a good way to serialize the form you are working on for Ajax.
var result = $(this).closest('form').serialize();
I'm new to PHP here and struggling with an issue. I've created a form to submit information to a powershell script on the back end. I have one drop down field (telephone) that is pulling from mysql and populating. That part is working great. The issue that I am having is that when i go to post the data and pass it to the powershell script that field (telephone) is being passed as blank. I'm not sure where I may have caused the issue and looking for some help here.
Here is what I have. I'd like to keep it in PHP if possible.

<?php
// If there was no submit variable passed to the script (i.e. user has visited the page without clicking submit), display the form:

<form name="testForm" id="testForm" action="BTAM2.php" method="post" /> <br />
First Name: <input type="text" name="SAMname" id="SAMname" maxlength="20" /><br /> <br/>

}
echo '</select>';

<input type="submit" name="submit" id="submit" value="Create User" />
</form>
<?php
}
// Else if submit was pressed, check if all of the required variables have a value:
elseif((isset($_POST["submit"])) && (!empty($_POST["SAMname"])))
{
// Get the variables submitted by POST in order to pass them to the PowerShell script:
$firstname = $_POST["SAMname"];
$telenumber = $_POST["phonenum"];
var_dump($_REQUEST);
}
// Else the user hit submit without all required fields being filled out:
else
{
echo "Sorry, you did not complete all required fields. Please go back and try again.";
}
?>
I've resolved my own issue. in the line
echo "<option value='". $row['id']."'>".$row['btphonenumber']
I should have had
echo "<option value='". $row['btphonenumber']."'>".$row['btphonenumber']
