if (!$result2) {
printf("Error: %s\n", mysqli_error($conn));
exit();
}
$options = "";

Iam able to select the material but on selection of material no material description auto populates.
Thanks for the help
PHP is case sensitive. Be careful about naming variables.
foreach contains upper case variable, while echo - lowercase. Also in echo you have space after variable and before opening bracket.
$MaterialDescription
$materialDescription_["MaterialDescription"]

In this code when I click on edit button then it will go to edit.php page where I get id from url and run update query after updating table college the data will update but when I move from edit page to index.php page the data will remain same but in database update data will be there. So, How can I fix this issue ?
Thank You
Check for caching. It could be that the browser is not going to the server in order to get the contents of index.php, as it thinks it has it.
Try calling index.php with a variable, like:
Home
i have the following tables that i want to display case number, defendant name,accussed name, judge name, date of hearing and type of hearing
<?php while($row=mysqli_fetch_array($search_result)):?>
<tr>
<td> <?php echo $row['CaseNO'];?></td>
<td> <?php echo $row['DefendantName'];?></td>
<td> <?php echo $row['AccussedName'];?></td>
<td> <?php echo $row['JudgeName'];?></td>
<td> <?php echo $row['DateOfHearing'];?></td>
<td> <?php echo $row['TypeOfHearing'];?></td>
</tr>
<?php endwhile;?>
THIS IS MY WHOLE CODE
<?php
if(isset($_POST['search']))
{
$valueToSearch=$_POST['valueToSearch'];
$query="SELECT * FROM `cases` WHERE CONCAT (`CaseNO`, `JudgeName`, `DefendantName`, `AccussedName`, `DateOfHearing`, `TypeOfHearing`) LIKE '%".$valueToSearch. "%'";
$search_result=filterTable($query);
}
else
{
$query="SELECT `CaseNO`,`DefendantName`,`AccussedName`,`JudgeName`,`DateOfHearing`,`TypeOfHearing`
FROM cases";
$search_result=filterTable($query);
}
function filterTable($query)
{
$connect=mysqli_connect("localhost","root","","mlc");
$filter_Results=mysqli_query($connect, $query);
return $filter_Results;

In select query you just give asscending order
SELECT CaseNO,DefendantName,AccussedName,JudgeName,DATE(DateOfHearing) AS DateOfHearing,TypeOfHearing
FROM tblname
ORDER BY DateOfHearing
Or use jquery datatable https://www.datatables.net/
You can sort the the records according to the date of hearing in your query. And simply put it in echo.
Here is a snippet :
<?php
$connect=new mysqli("localhost","root","");
mysqli_select_db($connect,'database');
$query=mysqli_query($connect,"SELECT * FROM table_name");
echo"<table><tr>";
while($row=mysqli_fetch_array($query))
echo '<td>Case Number: '.$row['case_number'].'</td><td>Defendant Name: '.$row['defendant_name'].'</td><td>Accused name: '.$row['accused_name'].'</td><td>judge name: '.$row['judge_name'].'</td><td>Date of HEaring: '.$row['date_of_hearing'].'</td><td>type of hearing: '.$row['type_of_hearing'].'</td>';
echo "</tr></table>";
?>
According to my comments
You can directly give ASC or DESC command in query. Like:
SELECT column_name, column_name FROM table_name ORDER BY column_name ASC|DESC, column_name ASC|DESC;
I have 3 tables in my database (standards, courses, students). I want to display Fname and gender from students table enrolled in selected 'standard' and 'course' from dropdown - but the "submit" button doesn't seem to work. The code is as shown below. I am sure it is connected to the database as the dropdowns for 'courses' and 'standards' work:

$result1 = mysql_query($query1);
while($rows1 = mysql_fetch_array($result1)){
$standardID = $rows1['id'];
$rowsData1 = $rows1['standardName'];

Inscribe the input elements within a form tag with post as method. Input elements with type submit are used for submission of forms.
You only do anything with the submitted form data if that data includes a submit field.
if(isset($_POST['submit'])){
However you have:
<input type="submit" name="submit" id="submit"/>
Your submit button don't have a value, so nothing will be included in the form data for it.
I have some combobox with onchange event, and they're reset each other when selected the orther one of them, does any suggest how to retain the value on the page? this my script :

<td colspan="6"></td>

hope any suggestion for resolved of my problem with them,,
onchange="submit(this)" means that you want to submit the form when the value of the combobox changes. So, when the form is sent, the page reloads and you get the default value of your form.
To restore the chosen value, I would do something like :
<select name="select_kabkota" style="width:18px;" onchange="submit(this)">
<option>KAB/KOTA</option>
<?php
if(isset($_POST['select_kabkota']))
$select_kabkota=$_POST['select_kabkota'];
while($row_kabkota=$result_kabkota->fetch_assoc())
{
$selected = $select_kabkota == $row_kabkota['kab_kota'] ? 'selected="selected"' : '';
echo "<option ".$selected." >".$row_kabkota['kab_kota']."</option>";
}
?>
</select>
I have 2 dropdowns on my HTML page : The first drop down contains the database column names based on which the the second dropdown would be populated i.e.
I have a single table with fields: <Student Name, Degree, City> and following would be the entries;
1. "A", "BS", "New York"
2. "B", "BS", "Chicago"
3. "C", "MS", "Boston"
4. "D", "MS", "New York"
So my first dropdown would contain the column names i.e. "Degree" and "City".
If I select "Degree", the 2nd dropdown should populate "BS" and "MS" and if I select "City", the 2nd dropdown should select "New York", "Boston" and "Chicago".
How can I go about with the implementation?
[Adding my code]:
the changeSecond(first) method remains exactly the same as you suggested
<body>
<form method="POST" action="" name="mainForm">
<table>
<tr>
<td> Filter by: </td>
<td>
<div id="first">
<select onChange="changeSecond(this.value)">
<option value="1">All</option>
<option value="2">Degree</option>
<option value="3">City</option>
</select>
</td>
</tr>
<tr>
<td> </td>
<td>
<div id="second">
<select name="val">
<option value=""></option>
</select>
</div>
</td>
</tr>
</table>
</form>
</body>
And this is the second_script.php as you suggested:
<?
$link = mysql_connect("localhost", "root", "");
if (!$link)
{
die('Could not connect: ' . mysql_error());
}
if (mysql_select_db("myDatabase", $link))
{
$first=mysql_real_escape_string($_REQUEST["first"]);
$query="SELECT ".$first." FROM myTable GROUP BY ".$first;
$data=mysql_query($query);
echo "<select id=\"second\">";
while($row=mysql_fetch_row($data))
{
echo "<option value=\"".$row[0]."\">".$row[0]."</option>";
}
echo "</select>";
}
echo mysql_error();
?>
code for the main file in which you want to populate drop down based on other
in below example i show localities in child dropdown for that city that is selected in parent drop down
<script type="text/javascript">
function city_locality(val)
{
// alert (val);
url="<?php echo $this->baseurl ?>/components/com_ezportal/includes/query.php";
data="stid="+val;
$.post(url,data,function(data){
$("#locid").html(data);
});
}
</script>
<select name="filter_1state" id="filter_1state" onChange="city_locality(this.value)">
<option value="0">-- Select City --</option>
<option value="1">Lahore</option>
<option value="2">Karachi</option>
<option value="3">Islamabad</option>
<option value="4">Quetta</option>
<option value="5">Multan</option>
</select>
code for the file query.php
<?php
$link = mysql_connect('localhost', 'root', '');
mysql_select_db('mydatabase');
if (isset($_POST['stid']))
{
$stid = $_POST['stid'];
$query= mysql_query("SELECT id,ezcity FROM tbl_locality WHERE stateid = '".$stid."' GROUP BY ezcity");
?>
<option value="0">-- Select Locality --</option>
<?php
while($row = mysql_fetch_array($query))
{
?>
<option value="<?php echo $row['id']?>"><?php echo $row['ezcity']?> </option>
<?php
}
}
?>
If you want a more dynamic solution (that will accommodate changes to the background DB) you can do something like this on your page:
<script>
function changeSecond(first){
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 res=xmlhttp.responseText;
document.getElementById("second").innerHTML=res;
}
}
xmlhttp.open("GET","second_script.php?first="+first,true);
xmlhttp.send();
}
</script>
...
<select onChange="changeSecond(this.value)">
<option value="Degree">Degree</option>
<option value="City">City</option>
</select>
<div id="second"><select><option value=""></option></select></div>
and then a script similar to:
<?php
//database connection
$first=mysql_real_escape_string($_REQUEST["first"]);
$query="SELECT ".$first." FROM tablename GROUP BY ".$first;
$data=mysql_query($query);
echo "<select>";
while($row=mysql_fetch_row($data)){
echo "<option value=\"".$row[0]."\">".$row[0]."</option>";
}
echo "</select>";
?>
I guess for real flexibility you'd also want to dynamically populate that first one using mysql_field_name in another script similar to above
You could either have all the dropdown needed preloaded and hidden, and show them when the 'change' event is triggered in the first dropdown, or have two dropdowns and empty it on that same 'change' event.
If you choose the second approach you should buffer the data to insert in the dropdown list, partially or totally
You can use ajax for this purpose

<form method="POST" action="" name="mainForm">
