i want to get the index of td that the user clicked , i have an html table fill from database using php ...
this is my index.php :
<html>
<head>
<title>Last 10 Results</title>
</head>
<body>
<table>
<thead>
</thead>
<tbody>
<tr>
<?php
session_start();
$connect = mysqli_connect("localhost","root","","test");
if (!$connect) {
die(mysql_error());
}
$results = mysqli_query($connect,"SELECT * FROM family where parent_id = 0");
while($row = mysqli_fetch_assoc($results)) {
?>
<td onclick="window.location='index2.php'"
<?php $id = $row['id'];
$_SESSION['varname'] = $id;?>>
<?php echo $row['name']?> <br/>
<?php echo $row['description']?> <br/>
<?php echo $row['parent_id']?> <br/>
</td>
<?php
}
?>
</tr>
</tbody>
</table>
</body>
</html>
this is my index2.php :
<html>
<head>
<title>Last 10 Results</title>
</head>
<body>
<table>
<thead>
</thead>
<tbody>
<tr>
<?php
session_start();
$gg = $_SESSION['varname'];
echo $gg;
$connect = mysqli_connect("localhost","root", "","test");
if (!$connect) {
die(mysql_error());
}
$results = mysqli_query($connect,"SELECT * FROM family where parent_id = '$gg' ");
while($row = mysqli_fetch_array($results)) {
?>
<td>
<?php echo $row['id']?> <br/>
<?php echo $row['name']?> <br/>
<?php echo $row['description']?> <br/>
<?php echo $row['parent_id']?> <br/>
</td>
<?php
}
?>
</tr>
</tbody>
</table>
</body>
</html>
now i want to take the "id" of the td that the user click on,, but this code always give me the last id in my database ...
what can i do ?
Replace in Index.php:
<td onclick="window.location='index2.php'"
With:
<td onclick="window.location='index2.php?parent_id=<?php echo $row['id']; ?>'"
And in
Index2.php:
$gg = $_SESSION['varname'];
With:
$gg = (int)$_GET['parent_id'];
It's better to use $_GET variable for this than $_session (urls are search engine friendly)

To do list:
I have created the HTML and php code to insert data into the database, and read from it.
Database is looking like this:
task_id |task_desc |task_target |task_finished_date |task_status
40 |test p |2020-07-25 |2020-07-23 |completed
Task_target and task_finished_date are using type date in the database.
task_target is getting value on creation of the task, and task_finished_date is getting automatically value when we mark the job completed using now():
$task_id = $_GET['completed'];
mysqli_query($db, "UPDATE tasks SET task_status = 'completed' WHERE task_id=". $task_id);
mysqli_query($db, "UPDATE tasks SET task_finished_date = now() WHERE task_id=". $task_id);
mysqli_query($db, "ORDER BY task_finished_date DESC ". $task_id);
header("Location: index.php" );
}
I am currently trying to program it when some task is completed AFTER the deadline to be displayed in "Failed" table, and if is closed before the deadline to be displayed in completed table.
<tbody>
<?php $i = 1; while ($row = mysqli_fetch_array($finished_tasks)) { ?>
<tr>
<?php
if($targetd > $finished_d){ ?>
<td class="successful"> <?php echo $i; ?> </td>
<td class="successful"> <?php echo $row['task_desc']; ?> </td>
<td class="successful"> <?php echo $row['task_finished_date']; ?> </td>
<?php }?>
</tr>
<?php $i++; } ?>
</tbody>
<thead>
<tr>
<th>N</th>
<th>Failed Tasks</th>
<th style="width: 197px;">Task finished time</th>
</tr>
</thead>
<tbody>
<?php $i = 1; while ($row = mysqli_fetch_array($finished_tasks)) { ?>
<tr>
<?php
if($targetd < $finished_d){ ?>
<td class="failed"> <?php echo $i; ?> </td>
<td class="failed"> <?php echo $row['task_desc']; ?> </td>
<td class="failed"> <?php echo $row['task_finished_date']; ?> </td>
<?php }?>
</tr>
<?php $i++; } ?>
</tbody>
As in the $finished_tasks variable i have storing the values for the completed tasks:
$finished_tasks = mysqli_query($db, "SELECT * FROM tasks WHERE task_status = 'completed' ");
$finished_task_time = mysqli_query($db, "SELECT task_finished_date FROM tasks WHERE task_status = 'completed' ");
$planned_target_time = mysqli_query($db, "SELECT task_target FROM tasks WHERE task_status = 'completed' ");
while ($row = mysqli_fetch_array($finished_tasks)) {
$targetd = $row['task_target'];
$finished_d = $row['task_finished_date'];
Have tried to get the deadline(task_target)and target(task_finished_date) and insert them in both variables and then compare them, and based on this comparison to display them where I want, but the logic here is not right I think.
How I can separate the tasks based on the desired condition?
Entire Code Below:
<?php
// initialize errors variable
$errors = "";
// connect to database
$db = mysqli_connect("localhost", "root", "", "todo");
// insert a quote if submit button is clicked
if (isset($_POST['submit'])) {
if (empty($_POST['task_desc'])) {
$errors = "You must fill in the task";
}else{
$task_desc = $_POST['task_desc'];
$task_target = $_POST['task_target'];
$sql = "INSERT INTO tasks (task_desc, task_target) VALUES ('$task_desc', '$task_target')";
mysqli_query($db, $sql);
header('location: index.php');
}
}
// delete task
if (isset($_GET['del_task'])) {
$task_id = $_GET['del_task'];
mysqli_query($db, "DELETE FROM tasks WHERE task_id=".$task_id);
header('location: index.php');
}
if(isset($_GET['completed'])){
$task_id = $_GET['completed'];
mysqli_query($db, "UPDATE tasks SET task_status = 'completed' WHERE task_id=". $task_id);
mysqli_query($db, "UPDATE tasks SET task_finished_date = now() WHERE task_id=". $task_id);
mysqli_query($db, "ORDER BY task_finished_date DESC ". $task_id);
header("Location: index.php" );
}
// select all tasks if page is visited or refreshed
$tasks = mysqli_query($db, "SELECT * FROM tasks WHERE task_status = 'Active' ");
?>

Your question is quite ambiguous, what kind of error or unexpected output are you getting?
Had to strip your code of the HTML part and the PHP part not affecting the logic, here's what I have.
$finished_tasks = mysqli_query($db, "SELECT * FROM tasks WHERE task_status = 'completed' ");
$finished_task_time = mysqli_query($db, "SELECT task_finished_date FROM tasks WHERE task_status = 'completed' ");
$planned_target_time = mysqli_query($db, "SELECT task_target FROM tasks WHERE task_status = 'completed' ");
while ($row = mysqli_fetch_array($finished_tasks)) {
$targetd = $row['task_target'];
$finished_d = $row['task_finished_date'];
$i = 1;
while ($row = mysqli_fetch_array($finished_tasks))
{
if($targetd > $finished_d)
{
echo $i;
echo $row['task_desc'];
echo $row['task_finished_date'];
$i++;
}
$i = 1;
while ($row = mysqli_fetch_array($finished_tasks))
{
if($targetd > $finished_d)
{
echo $i;
echo $row['task_desc'];
echo $row['task_finished_date'];
}
$i++;
}
}
All three while loops assign a value to the $row variable. This would cause some unexpected results as some values may be skipped.
You're referencing the SQL result indexes inappropriately.
I have managed to find a easy fix of my question.
First of all thanks to all who tried to help me and advised way of effective learning.
Really like this place.
So, on the answer:
As in the begging i have described that the Deadline of the task is defining during the creation of the task, and the closing time is getting to the database when the user click Completed button.
So i have decided to have the sort directly into the database modifying the queries like this:
$finished_tasks = mysqli_query($db, "SELECT * FROM tasks WHERE task_status = 'completed' AND task_finished_date < task_target ");
$finished_failed_tasks = mysqli_query($db, "SELECT * FROM tasks WHERE task_status = 'completed' AND task_finished_date > task_target ");
In this way i have all of the completed successfully tasks in $finished_tasks variable and all of the failed in $finished_failed_tasks, after that the displaying in the page is easy.
I am not quite sure if this is practical solution, but in this way working as i desired.
Next step is to strip and refactor the code as you suggested.
Once again, thanks really much and have a nice day.

I am using notepad, xampp and mysql and phpMyadmin to create a football prediction website. On the prediction page I have a page showing the fixture in a table. I want the use to be able to post a Home_Sore and Away_Score for each corresponding fixture using a series of dropdown menus with numbers 1-20.
For example:
Fixture_ID|Home_Team|Home_Score|Away_Score|Away_Team|
1 Man United <Dropdown> <Dropdown> Spurs
Is this possible? I am new to php coding and would appreciate any help i get!:)

You can do this by including something like this in td tag
<select name="mySelect">
<?php $result= mysql_query('SELECT * FROM fixtures'); ?>
<?php while($row= mysql_fetch_assoc($result)) { ?>
<option value="<?php echo $row['your_column_name'];?>">
<?php echo $row['your_column_name']; ?>
</option>
<?php } ?>
</select>
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);
?>
<html>
