Hello I have an issue with updating MySQL using PHP form in Netbeans the issue that occurs is:
"Notice: Undefined variable: fetched_row in C:\Xampp\htdocs\Resume_DB\PHP\Edication_Edit.php on line 75"
In all 4 of my text boxes. The code I have is :
<?php
mysql_connect("localhost", "root", "");
mysql_select_db("cs266db_db1");
if(isset($_GET['edit_id']))
{
$sql_query="SELECT * FROM education Where Edit_Education=".$_GET['edit_id'];
$result_set= mysql_query($sql_query);
$fetched_row= mysql_fetch_array($result_set);
}
if(isset($_POST['btn_update']))
{
//variables for input data
$Class = $_POST['Class'];
$Discipline = $_POST['Discipline'];
$Description = $_POST['Description'];
$Term = $_POST['Term'];
//sql query for update data
$sql_query = "UPDATE Education SET Class='$Class', Discipline='$Discipline', Description='$Description', Term='$Term' WHERE Education_Edit=".$_GET['edit_id'];
//sql query execution function
if(mysql_query($sql_query))
{
?>
<script type='text/javascript'>
alert('Data Has Been Updated');
window.location.href='Eduaction.php';
</script>
<?php
}
else
{
?>
<script type='text/javascript'>
alert('Error Occured while Updating Data');
</script>
<?php
}
//sql query execution function
}
if(isset($_POST['btn-cancel']))
{
header("Location: Education.php");
}
?>

Any thoughts? Thanks for your help guys
The problem is that fetched_row is only assigned when $_GET['edit_id'] is set. Otherwise it does not exist, but you're still trying to use it, even if $_GET['edit_id'] is not set.
Change
<td><input type="Text" name="Term" placeholder="Term" value="<?php echo $fetched_row['Term']; ?>" required</td>**
To:
<td><input type="Text" name="Term" placeholder="Term" value="<?php echo (isset($fetched_row['Term']))? $fetched_row['Term'] : ''; ?>" required</td>**
It seems instead of "Edit_Education" you are using "Education_Edit" in update query or instead of "Education_Edit" you are using "Edit_Education" in select query.
$sql_query="SELECT * FROM education Where Edit_Education=".$_GET['edit_id'];
$sql_query = "UPDATE Education SET Class='$Class', Discipline='$Discipline', Description='$Description', Term='$Term' WHERE Education_Edit=".$_GET['edit_id'];
change if(isset($_POST['btn_update'])) to if(isset($_POST['btn-update'])) because in html button tag you named button as btn-update .
In update query change column name Education_Edit change to Edit_Education

I want to change the background color of a specific clicked table row. It also should change it back to the original color. Back and forth from red to green. And it should also check the checkbox. Green = checkbox checked/ Red = checkbox unchecked.
The rows look like this
<tr id="<?php echo $row['id'] ?>" value="<?php echo $row['id'] ?>">
and for JQUERY I have this:
$(document).ready(function() {
$('.table tr').click(function(event) {
var id = $(this).attr('id');
var bcolor = $('.task').css('background-color');
console.log(id);
console.log(bcolor);
if (event.target.type !== 'checkbox') {
$(':checkbox', this).trigger('click');
if (bcolor == 'rgb(205, 92, 92)') {
$('.task').css('background-color', 'green');
} else {
$('.task').css('background-color', 'indianred');
}
};
});
});
How can I use the var id = $(this).attr('id'); to change the background color only for the specific clicked row?
Right now it makes every row green by clicking on any of them.

You can use toggleClass of jQuery:
// css for put in your element
.common-class {
background-color: #ff0000; // replace for your color
}
.highlight-class {
background-color: #0000ff !important; // replace for your color
}
$('your-selector').toggleClass('highlight-class'); // jQuery
Bensilson's answer helped me and i want to clarify what i have done:
I delete the class='task'inside the <td> and put it into the <tr> - Tag.
I've done a .highlighttask{background-color: green !important} inside the css.
And inside the js i've done
$(document).ready(function() {
$(".table tr").on('click', function() {
var checked = $(this).find('input[type="checkbox"]');
checked.prop('checked', !checked.is(':checked'));
$(this).toggleClass('highlighttask');
});
});
Now it overrights the background-color on a specific row AND it checks the checkbox of the specific row.
Thanks!
im working with a dynamic form that the end user can enter as much material as he wants by clicking on an add button, this button calls a JavaScript function that inserts a drop-down list into my form. if i removed the select section it works and it calls the input field but if i add the select section it doesn't call the function.

Much appreciate, Thanks.
The title of your question is misleading. But if I got it right you actually succeed in querying your data correctly and refreshing the number of records with your refresh button.
You real question is how to persist the default value of the dropdown after a logout.
By mentioning your logout feature I assume you have users and a user table in your database.
From here you have two solutions I can think of:
1. Save the users preferences like the default value of your dropdown within your users table or create a separated table dedicated for this purpose.
2. Store users preferences in cookies

If you use jQuery:
$("#txt_tot").val($("#txt_oral").val() + $("#txt_written.val());
http://api.jquery.com/val/
If you don't want to use jQuery for this project
document.getElementById('txt_tot').value = document.getElementById('txt_oral').value + document.getElementById('txt_written').value;
I have got my answer in threadliyakat's answer
I just changed the value * to + and added parseInt to make input values in number. function multiply changed in calculation
and onkeyup='calculate(".$i.");' in first user input and second user input .
answer is working in id='txt_tot".$i."'
its working well!!!!

in submit.php you can check like this
