Make dropdown sort list

Make dropdown sort list - php

I have this php code with a drop down pulling info from the database but cannot seem to figure out how to get the drop down selection to sort the list...
The drop down is showing the course name as the label but when selected needs to sort the list by course id.
Visit Here to see the table in action
<?php
$connect = mysql_connect('localhost','emscompl_paramed','PASSOWRD) or die(mysql_error());
$selectdb = mysql_select_db('emscompl_joom1283',$connect);
$sel = "SELECT us.fullname, s . *
FROM registered_users AS `us`
LEFT OUTER JOIN course_students AS s ON s.userid = us.userid";
$ressel = mysql_query($sel);
$fetchsel = mysql_fetch_array($ressel);
?>

If you want to sort your select box by id, then definitely use "ORDER BY" as Pachonk says above.
Also, I've noticed that your PHP below:
<option>
<? echo $options ?>
</option>
is outputting:
<option>
<option value="Some id">some text
<option value="some other id">some other text
... repeat for all options
</option>
You should remove the first from around the PHP (you are placing an tag in the php echo statement anyway) and place the tag in your php code above so that every has an
like:
$result = mysql_query($sql) or die (mysql_error());
while ($row = mysql_fetch_array($result))
{
$id=$row["id"];
$course=$row["coursename"];
$options.="<OPTION VALUE=\"$id\">".$course . "</option>";
^^^^^^^^^^^^^ added these
}
?>
// removed <option>
<? echo $options ?>
// removed </option>
</select>
Of course, you could just have the php in the while clause output your option right there and then too.
Hope that helps in some way.

Style is not being applied except for the first row from sql query in html code

I'm retrieving all the rows from sql database through a query, and i'm using a loop to get all the rows
I have a style.css file which i'm specifying a style for the , however, only the first row is receiving the style and the style is not being applied to the rest.

It is not a CSS problem, it is because you are closing your </table> in the loop, so it is ending your table after the first tr.
Just remove it from the loop:
<?php
$con = new PDO("mysql:host=localhost;dbname=data",'root','admin123');
if (isset($_POST["submit"])) {
$str = $_POST["search"];
$sth = $con->prepare("SELECT * FROM `questions` WHERE question LIKE '%$str%'");
$sth->setFetchMode(PDO:: FETCH_OBJ);
$sth -> execute();
?>
<table>
<tr>
<th>Project</th>
<th>Question</th>
<th>Sample</th>
</tr>
<?php
for ($a=0;$row = $sth->fetch();$a++) {
?>
<tr>
<td><?php echo $row->Proj_Name; ?></td>

That's because $title is a string literal and it needs to be quoted. You really should use a prepared statement for everything though, and will help safeguard against a potential SQL injection.

I need to insert data into mysql from a dynamic table with selects created with PHP

Wondering if someone could help me update mysql table with data from a couple of selects created dynamically with PHP, I have created the following code, but it seems not to be working, really appreciate your help:
`include_once('../includes/connection.php');`
// Query that retrieves events
$con = "SELECT * FROM evenement WHERE approved = 'no' ORDER BY id";
$result = mysqli_query($connection, $con);
if($con){
$registry = mysqli_affected_rows($connection);
if($registry > 0){
echo '

I don't think that I have solved all your issues, but this might help you further.

$i++;
}

$con = "SELECT * FROM evenement WHERE approved = 'no' ORDER BY id";
$result = mysqli_query($connection, $con) or die(mysqli_error($connection));

You should try this, your update syntax might causing you the problem
$udpate_qry = "UPDATE evenement
SET allDay='$allDay', approved='$ap_re'
WHERE id='$id'";

Mr. Radical, you are the man, I was able to update my table with your suggested code, I just needed to add $length = count($allDay) and then change the while loop to while(($id) && ($i < $length)) that made it. Really appreciate your help.

Send $_GET using php or jquery

my index.php page has something like this:
if(isset($_GET['page'])) {
switch ($_GET['page']) {
case 'login':
include('login.php');
break;
case 'log_out':
$_SESSION['loggedin'] = false;
include('loggedout.html');
break;
case 'profile':
include('profile.php');
break;
case 'contact_us':
include('contact.html');
break;
default:
include('home.html');
break;
}
} else {
include('home.html');
}
Now I can easily call on a new page when a link is pressed or form is submitted i.e:
Home Contact Us
but what if I had an all in one form... It would need to be able to send a request through PHP code to my index.php to show the logged in page or reshow the login.php page but I cant seem to find anything that would allow me to send a request in php script i.e:
<?php
if(..) {
send request to index.php i.e index.php?page=profile
}
?>
The reason I need this is my index.php uses divs as formatting and thus if I dont request pages through index.php they are displayed in a new html (i.e it doesnt have my navigation bars etc)
As per a comment by #HydraIO and others how would this be done using JQuery?
Here is some code:
lgoin.php:
<?php session_start(); ?>

I see the alert but am redirected to a blank html like before (even than before at least the form was reloaded

It sounds like you might want to evaluate all the data inside your index page first and do a page redirect by setting a header inside php to the same index page with the get query updated to whatever you want it to be.
header("Location: http://www.example.com/index.php?page=profile");
exit();
make sure you don't output any html with echo or any other way before you do the redirect. If your script heavily uses echo before that you can look into outputbuffering your echos.

PHP is a server-side language, and not dynamic. You want to use javascript (jQuery in my example).
$_GET = <?php echo json_encode($_GET); ?>;
if($_GET['val'] == some_value){
$.get(index.php?getvar=getval, {
complete: function(){
$('#div').val("YOUR OUTPUT"); // *
}
});
}
*This can be any code you feel like, you could replace the div with the entire php file if you chose to

How to sort rows of HTML table that are called from MySQL

I know it's such a basic thing, but a Google search hasn't shown me how to re-sort the rows after clicking the th links.
I've got this:
<table border="1">
<tr>
<th>Type:</th>
<th>Description:</th>
<th>Recorded Date:</th>
<th>Added Date:</th>
</tr>
<?php
while($row = mysql_fetch_array($result)){
?>
<tr>
<td><?php echo $row['type'] ?></td>
<td><?php echo $row['description'] ?></td>
<td><?php echo $row['recorded_date'] ?></td>
<td><?php echo $row['added_date'] ?></td>
</tr>
<br />
<?php
}
mysql_close();
?>
</table>
I need to be able to click type and sort alphabetically, and click on either Recorded Date or Added Date and sort by date. I see that I need to have the MySQL queries do this, but do I set them up as conditionals with a href tags?

The easiest way to do this would be to put a link on your column headers, pointing to the same page. In the query string, put a variable so that you know what they clicked on, and then use ORDER BY in your SQL query to perform the ordering.
The HTML would look like this:
<th>Type:</th>
<th>Description:</th>
<th>Recorded Date:</th>
<th>Added Date:</th>
And in the php code, do something like this:
<?php
$sql = "SELECT * FROM MyTable";
if ($_GET['sort'] == 'type')
{
$sql .= " ORDER BY type";
}
elseif ($_GET['sort'] == 'desc')
{
$sql .= " ORDER BY Description";
}
elseif ($_GET['sort'] == 'recorded')
{
$sql .= " ORDER BY DateRecorded";
}
elseif($_GET['sort'] == 'added')
{
$sql .= " ORDER BY DateAdded";
}
$>
Notice that you shouldn't take the $_GET value directly and append it to your query. As some user could got to MyPage.php?sort=; DELETE FROM MyTable;

That's actually pretty easy, here's a possible approach:
<table>
<tr>
<th>
Type:
</th>
<th>
Description:
</th>
<th>
Recorded Date:
</th>
<th>
Added Date:
</th>
</tr>
</table>
<?php
$orderBy = array('type', 'description', 'recorded_date', 'added_date');
$order = 'type';
if (isset($_GET['orderBy']) && in_array($_GET['orderBy'], $orderBy)) {
$order = $_GET['orderBy'];
}
$query = 'SELECT * FROM aTable ORDER BY '.$order;
// retrieve and show the data :)
?>
That'll do the trick! :)

that will sort the table using ajax

This is the most simple solution that use:
// Use this as first line upon load of page
$sort = $_GET['s'];
// Then simply sort according to that variable
$sql="SELECT * FROM tracks ORDER BY $sort";
echo '<tr>';
echo '<td>Title<td>';
echo '<td>Album<td>';
echo '<td>Artist<td>';
echo '<td>Count<td>';
echo '</tr>';

It depends on nature of your data. The answer varies based on its size and data type. I saw a lot of SQL solutions based on ORDER BY. I would like to suggest javascript alternatives.
In all answers, I don't see anyone mentioning pagination problem for your future table. Let's make it easier for you. If your table doesn't have pagination, it's more likely that a javascript solution makes everything neat and clean for you on the client side. If you think this table will explode after you put data in it, you have to think about pagination as well. (you have to go to first page every time when you change the sorting column)
Another aspect is the data type. If you use SQL you have to be careful about the type of your data and what kind of sorting suites for it. For example, if in one of your VARCHAR columns you store integer numbers, the sorting will not take their integer value into account: instead of 1, 2, 11, 22 you will get 1, 11, 2, 22.
You can find jquery plugins or standalone javascript sortable tables on google. It worth mentioning that the <table> in HTML5 has sortable attribute, but apparently it's not implemented yet.
