I'm having trouble searching the date field of mysql database.. I have a html form..that allows the user to choose 3 different ways to search the database.. field 1 is student_id, field 2 is lastname, field 3 is date. Well when i run the program and choose student id, I get the proper result back, when i do the same using last name I get the proper result back, but when i use date..I do not get any return. I happen to know what the result should be because i see it in the database..and besides that its the same data record as the student id, and last name. I think it might have something to do with format, but I can't figure it out..
I do not know aJax so please don't suggest ajax code right now.
here is the html code.

return false;

I Believe you are using like to get the Exam Dates for that session or month so you can use this
Using DATE_FORMAT function
SELECT * FROM records WHERE DATE_FORMAT(examDate, '%Y %m') = DATE_FORMAT('$typeValue', '%Y %m') ORDER BY examDate
or may be you are looking for a specific date than
SELECT * FROM records WHERE examDate = '$typeValue'

At the moment you have multiple forms - one per table row, so each <select is inside its own form. You can't submit multiple forms at once from a HTML page. Also your existing forms seem to be missing the </form> tag so they will be invalid anyway.
Therefore, to be able to submit all the <select values at the same time, you need a single form, which has the entire table contained within it.
For example:
<form action='wypozyczalnia.php' method='post'>
<table>
<?php
if ($ile>=1)
{
//pętle wyświetlająca wszystkie zwrócone z zapytania wpisy
for ($i = 1; $i <= $ile; $i++)
{
//pobranie rzędu jako tablicę asocjacyjną
$row = mysqli_fetch_assoc($rezultat);
//przypisanie każdej kolumny do odpowiedniej zmiennej
$title = $row['title'];
$author = $row['author'];
$description = $row['description'];
$available = $row['available'];
echo
"<tr>
<th> ".$title." </th>
<th> ".$author." </th>
<th> ".$description." </th>
<th>";
if($available==1)
{
echo "TAK";
}
else
{
echo "NIE";
}
"</th>";
if(isset($_SESSION['zalogowany']) && ($_SESSION['zalogowany']==true) && $available==1)
{
echo "<th>
<select name='idksiazki[]' >
<option value=$i;>NIE</option>
<option value=$i;>TAK</option>
</select>
</th>";
}
echo "</tr>";
}
}
?>
</table>
</form>
P.S. A note about HTML semantics: <th> is mean to indicate a table heading, e.g. the title of a column, or the main heading within a row. It should not be used for every cell in your table. <td> is for normal table cells. If you wish to make the text bold, use CSS instead.

First you need to copy the data from one table to another using INSERT ... SELECT syntax and only then you can delete.
You should be using prepared statements for this.
if (isset($_POST['save'])) {
// Prepared INSERT query
$stmt_insert = $conn->prepare('INSERT INTO bazarduepayment(date,item,paid,due,remark)
SELECT date,item,paid,due,remark FROM bazar WHERE sl=?');
// Prepare DELETE query
$stmt_delete = $conn->prepare('DELETE FROM bazar WHERE sl=?');
// Loop on all checkboxes selected
foreach ($_POST['check'] as $del_id) {
$stmt_insert->bind_param('s', $del_id);
$stmt_insert->execute();
$stmt_delete->bind_param('s', $del_id);
$stmt_delete->execute();
}
}
You could even simplify this to get rid of the foreach loop entirely.
I want to create a HTML Table, but the rows should be generated from the values from a mysql database. The problem is that I want to have a boolean box where the user can mark it, and then press a button to update the table in the database. How do I do such a thing ?
Code so far:
<?php
session_start();
require("connectToEvent_log.php");
$connectToEvent = connect2db();
$uid = '2'; // for the filnal version: #$_SESSION['uid'];
$view_event = "SELECT * FROM event_log WHERE uid = $uid";
$view_event_query = mysqli_query($connectToEvent, $view_event);
$row = mysqli_num_rows($view_event_query);
$print = mysqli_fetch_array($view_event_query);
?>
<html>
<head>
<title>Events</title>
</head>
<body>
<form action="viewEvents.php" method="POST">
<table border = '1'>
<tr>
<?php
while($row != 0){
echo "<td>".$print['hours']."</td>";
echo "<td>".$print['date']."</td>";
}
?>
</tr>
</table>
<form/>
</form>
</body>
</html>
You can easily iterate over the result from the mysqli_fetch_array function to create the table rows. Creating a checkbox markup is done easily, i assume that the table has a primary key id and the column, that stores the checkbox value (0 or 1) is called checkbox.
<?php
session_start();
require("connectToEvent_log.php");
$connectToEvent = connect2db();
$uid = '2'; // for the filnal version: #$_SESSION['uid'];
$view_event = "SELECT * FROM event_log WHERE uid = $uid";
$view_event_query = mysqli_query($connectToEvent, $view_event);
$num_rows = mysqli_num_rows($view_event_query);
$rows = mysqli_fetch_array($view_event_query);
?>

I have database table schedule with id, date, time, cabinet columns.
Also I have table cabinets with id, cabinetNumber, title columns.
I should generate table, but it should look like queue table.
cabinet 8,9,10,11,12,13,14,15,16
102 - - - + - - + - -
103 - + - - - - + - -
if time is busy it will be +, if free -.
I need modify my mysql query. And should be possible to change date (usege datepicker and Ajax) and change table rows values depend of date.
But if date does not exist, query will be empty and table will be without rows. How can i fixed it?
MySQL query :
$q = $_GET['date'];
$query = mysql_query("SELECT date,cabinet,
SUM(IF(ROUND(`time`)=8,1,0)) as h8,
SUM(IF(ROUND(`time`)=9,1,0)) as h9,
SUM(IF(ROUND(`time`)=10,1,0)) as h10,
SUM(IF(ROUND(`time`)=11,1,0)) as h11,
SUM(IF(ROUND(`time`)=12,1,0)) as h12,
SUM(IF(ROUND(`time`)=13,1,0)) as h13,
SUM(IF(ROUND(`time`)=14,1,0)) as h14,
SUM(IF(ROUND(`time`)=15,1,0)) as h15
FROM `schedule` WHERE date = '".$q."'
GROUP BY cabinet") or die(mysql_error());
?>
table :
<table class="table table-hover">
<tr class=".info"><td>Cab</td><td >8:00</td><td >9:00</td><td >10:00</td><td >11:00</td><td >12:00</td><td >13:00</td><td >14:00</td><td >15:00</td></tr>
<!-- -->
<?php while($data=mysql_fetch_array($query)) :?>
<tr>
<?php $cabinet = $data['cabinet']; ?>
<td><?=$cabinet ?></td>
<?php for($j=8; $j<=15; $j++) : ?>
<?php
$busy = $data['h'.$j];
?>
<?php if($busy>0 && $data['date']===$q ): ?>
<td class="busy"></td>
<?php else: ?>
<td class="free">
<form action="1.php" method="post">
<input type="hidden" name="time" value="<?= $j;?>" />
<input type="hidden" name="cabinet" value="<?= $cabinet;?>" />
<input type="submit" style="free" value="" name="sub"/>
</form>
</td>
<?php endif?>
<?php endfor ?>
</tr>
<?php endwhile ?>
</table>
And jQuery / Ajax:
<script>
$(function() {
$( "#datepicker" ).datepicker({ dateFormat: 'yy-mm-dd' });
});
$( ".date" ).on('change', function(){
var date = $('#datepicker').val();
$.ajax({
type:'get',
url:'table.php',
data : {
'date' : date
},
success: function(data) {
$('#result').html(data);
}
});
});
</script>
I had solwe my problem. I added new query query2 from cabinets table.
<?php $query2 = mysql_query("select cabinetNum from cabinets") ?>
<table class="table table-hover">
<tr class=".info"><td>Cab</td><td >8:00</td><td >9:00</td><td >10:00</td><td >11:00</td><td >12:00</td><td >13:00</td><td >14:00</td><td >15:00</td></tr>
<!-- -->
<?php while($data2=mysql_fetch_array($query2)): ?>
<?php $data=mysql_fetch_array($query) ?>
<tr>
<?php $cabinet = $data2['cabinetNum']; ?>
<td><?=$cabinet ?></td>
<?php for($j=8; $j<=15; $j++) : ?>
<?php
$busy = $data['h'.$j];
?>
<?php if($busy>0 ): ?>
<td class="busy"></td>
<?php else: ?>
<td class="free">
<form action="1.php" method="post">
<input type="hidden" name="time" value="<?=$j?>" />
<input type="hidden" name="cabinet" value="<?=$cabinet?>" />
<input type="hidden" name="date" value="<?=$q?>" />
<input type="submit" class="free" value="" name="sub"/>
</form>
</td>
<?php endif?>
<?php endfor ?>
</tr>
<?php endwhile ?>
</table>
The key is to keep the queries simple, use PHP to process and display the data. I will not go in to the altering of data with datapicker and ajax as you need to get the displaying correct first. Please take a look at this code and understand what it does and why it solves the problem of when there is no data for a date. You dont seem to have added the cabinet name in your table, so I kept it as an id. You can do a simple join in the query to get the cabinet name.

I have two entries in tblStudentDetails having RollNo = 0 and 1
But whenever I try to retrieve the data from the database I always get the first record i.e. RollNo = 0

$result = mysql_query($query);

You have not started a session with session_start().
