I am trying to create form by dynamically adding rows and deleting it when user clicks on delete button using php code,
below is my code to render first row while opening the form ,
<div class="selector-details" style="display:none">
<div class='newfield'>
<div id='container'>
<table id="tid">
<tr>
<td><?php echo CHtml::dropDownList('field_list','',$field_name); ?></td>
<td><?php echo CHtml::dropDownList('field_list','',$operator); ?></td>
<td><?php echo CHtml::textField('querybox'); ?></td>
<td> <?php echo CHtml::imageButton(Yii::app()->request->baseUrl.'/images/Trash.jpg',array('class'=>'trash-action')); ?></td>
<?php echo "<br>"; ?>
<td> <?php echo CHtml::dropDownList('condition_check','',$condition_check);?></td>
</tr>
</table>
</div>
</div>
<?php
echo CHtml::button('Add',array('class'=>'addfield-button','background-style'=>'none'));
how i should make call the above code to add rows and delete particular row when user clicks on the row delete button ? I am new to yii please provide any idea to go further.
$script = 'alert("hello")';
Yii::app()->getClientScript()->registerScript('#test', $script,CClientScript::POS_HEAD );
echo CHtml::button('Add',array('class'=>'addfield-button','background-style'=>'none','onclick'=>$script));
if you real want to use Yii style, you can open framework code and there is a good code that you want, search : CButtonColumn.php

Let's say for example column dropdown represents a type of membership and depending on the value of dropdown, I would like to be able to display a column next to it that indicates the maximum number of companions I could bring. Is there a way to do it via javascript or PHP or maybe SQL itself?
<?php
foreach ($dbh->query($sql) as $rows){
?>
<tr>
<td><?php echo $rows['name']?></td>
<td><?php echo $rows['email']?></td>
<td><?php echo $rows['number']?></td>
<td><?php echo $rows['org']?></td>
<td><?php echo $rows['dropdown']?></td>
<td><?php echo $rows['date']?></td>
</tr>
<?php
}
?>
Code:
<?php
foreach ($dbh->query($sql) as $rows){
?>
<tr>
<td id="<?=$rows['id']?>"><?php echo $rows['name']?></td>
</tr>
<?php
}
?>
By clicking on the ajax button you will take the ID attribute of the column, send a request with the received id and add the value to the column created next to it.
If I understand you correctly.
I have a page containing a database table with all the rows and columns.
What I am trying to do is to select all the rows I want and then delete them when I click on the button.
This is what I've done so far in the table.php page:
<?php
include "config.php"; //connection to database
incude "home.js";
$funcao="Select * from palavras";
$result=mysqli_query($link, $funcao);
?>
<button id="button_apaga" type="button" onclick="delete()" > DELETE </button>
<?php if($result->num_rows > 0) { ?>
<table class="table">
<tr>
<th>IdPalavra</th>
<th>Palavra</th>
<th>Grau de Dificuldade</th>
<th>Data</th>
<th>Hora</th>
<th>Selecionar</th>
</tr>
<?php while($row = mysqli_fetch_assoc($result)) { ?>
<tr role="row">
<td><?php echo $row['idpalavras']; ?></td>
<td><?php echo $row['palavra']; ?></td>
<td><?php echo $row['graudificuldade']; ?></td>
<td><?php echo $row['data']; ?></td>
<td><?php echo $row['hora']; ?></td>
<td><input type="checkbox" name="check" id="checkbox" /></td>
</tr>
<?php } ?>
</table>
<?php }
else{
echo "0 resultados";
} ?>
JavaScript Page (home.js):
function delete(id){
var check = document.getElementById('checkbox');
if(check.checked) {
// sql query
}
My question is how can I do que sql query considering it's in a different page. Can I just open php and put the query inside?
Also how can I receive all the IDs from the selected rows to the function?
Thank you in advance.
One approach would be to use AJAX. For the purpose of condensing the code, I'm going to also incorporate jQuery into this solution. I am also going to change your checkbox to an individual button link for the sake of making this a bit less code. A solution to delete multiple at the same time could work similarly to this, but since you're using AJAX most likely this is going to be easier for your users.
Modify table.php
<?php
include "config.php"; //connection to database
incude "home.js";
$funcao="Select * from palavras";
$result=mysqli_query($link, $funcao);
?>
<?php if($result->num_rows > 0) { ?>
<table class="table">
<tr>
<th>IdPalavra</th>
<th>Palavra</th>
<th>Grau de Dificuldade</th>
<th>Data</th>
<th>Hora</th>
<th>Selecionar</th>
</tr>
<?php while($row = mysqli_fetch_assoc($result)) { ?>
<tr role="row" class="palavras_row">
<td><?php echo $row['idpalavras']; ?></td>
<td><?php echo $row['palavra']; ?></td>
<td><?php echo $row['graudificuldade']; ?></td>
<td><?php echo $row['data']; ?></td>
<td><?php echo $row['hora']; ?></td>
<td>Delete</td>
</tr>
<?php } ?>
</table>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js?ver=3.3.1"></script>
<script type="text/javascript">
(function($) {
$(document).on('click', '.palavras_row a.palavras_delete', function() {
var _id = $(this).attr('data-id');
var _row = $(this).parent().parent();
$.ajax({
url: 'delete.php',
data: {
idpalavras: _id
},
type: 'POST',
dataType: 'json',
success: function(__resp) {
if (__resp.success) {
_row.remove(); // Deletes the row from the table
}
}
});
});
})(jQuery);
</script>
Create a new file in the same folder as your table.php and name it delete.php
<?php
$idpalavras = filter_input(INPUT_POST, 'idpalavras', FILTER_SANITIZE_NUMBER_INT);
$success = false;
if ($idpalavras) {
include "config.php"; //connection to database
$funcao="delete from palavras where idpalavras = " . $idpalavras;
$result=mysqli_query($link, $funcao);
$success = true;
}
header('Content-Type: application/json');
echo json_encode(array('success' => $success));
The solution above sends a simple command to your PHP backend where the delete query can be run by PHP. You cannot run a mysql command directly from javascript since that is frontend code.
This code is a functional solution, but it is abbreviated; a more complete solution would have more detailed handling of potential errors (either via AJAX or processing your delete query). It should also have some security on your delete.php to make sure unauthorized users aren't able to delete records without the proper permission to do so.
guys, I am doing a project in PHP where I should display in a page data from the database and remove from the page(not database) if I checkbox them using ajax. any source or link that could help me understand better this? thank you!!
p.s all I've done so far is deleting the data from the page and database at the same time
while($row = mysqli_fetch_array($result))
{
<tr id="<?php echo $row["id"]; ?>" >
<td><?php echo $row["id"]; ?></td>
<td><?php echo $row["name"]; ?></td>
<td><?php echo $row["surname"]; ?></td>
<td><input type="checkbox" name="id[]" class="delete" value="<?php echo $row["id"]; ?>" /></td>
**deleting method **
$.ajax({
url:'delete.php',
method:'POST',
data:{id:id},
success:function() {
for(var i=0; i<id.length; i++){
$('tr#'+id[i]+'').css('background-color', '#ccc');
$('tr#'+id[i]+'').fadeOut('slow');
If you're not deleting from the database then using AJAX isn't needed at all; use a javascript event listener that is triggered by a "delete selected" button or by the checkboxes themselves to remove the row from the table
I'm trying to get data from database using PHP this the Sql request you'll see that I have 3 tables but in table Milestoneevent I have various values for column libelle so I want to display like this
Id num libelle1 libelle2 libelle3 ..... sql reql request and php
select DISTINCT file.num,file.id as filenumber,file.numlta,milestones.id,milestones.libelle,milestoneevent.idmilestone,milestoneevent.dat,milestoneevent.idfile from file,milestones,milestoneevent where milestoneevent.idfile=FILE.num and milestoneevent.idmilestone=milestones.id
while (row=mysqlfetchassoc(
rs_result)) {
//print_r( $row ); // debug code ?>
<tr>
<td><input type='checkbox' name="approve[]" id="check" value=<?php echo $row['num']?>></td>
<td><?php echo $row['filenumber']; ?></td>
<td><?php echo $row['numlta']; ?></td>
<td><?php echo $row['designation']; ?></td>
<td><?php echo $row['libelle']; ?></td>
<td><?php echo $row['milestonedate']; ?></td>
</tr>
in the picture you see that a row cqn have multiple values for column libelle in different dates
edit
As requested in comments, here is my expected output:
I was forced to add picture here cause in comment discussion can not add it
You can use GROUP_CONCAT, in your query:
select...,GROUP_CONCAT(milestones.libelle SEPARATOR ';'),..FROM....WHERE...GROUP BY milestones.id
I have an admin panel that I am creating. I have a left panel section and then the right side which shows the div when the panel button is clicked. I created a fiddle to show what it looks like and to help me explain this...
https://jsfiddle.net/jq8c51c9/
In the Fiddle it works just like it should, but I took out all of my php. The problem is around the Announcements div, it shows the div for the League Dues under it. Also once you click on announcements and then click on another panel button, if I click on Announcements again the only thing that will show up is this..
Announcements Current Announcements
League Dues
Again this is NOT doing this in the Fiddle.
Here is the full code for the area that the issue resides in. I have been stuck on this forever and cannot figure out why I am having difficulties with only these two divs.
Does anyone see what it is that I am doing wrong?
Announcements
try {
//Prepare
$con = mysqli_connect("localhost", "", "", "");
if ($user_stmt = $con->prepare("SELECT `id` FROM users")) {
$user_stmt->execute();
$user_stmt->bind_result($user_id);
if (!$user_stmt) {
throw new Exception($con->error);
}
$user_stmt->store_result();
$user_result = array();
//while ($user_row = $user_stmt->fetch()) {
?>
<div class="announcement_success"></div>
<p>Add New Announcement</p>
<form action="" method="POST" id="insert_announcements">
<input type="hidden" value="<?php echo $userid; ?>" id="approved_id" name="user_id" />
<textarea rows="4" cols="50" id="announcement_message" name="message" class="inputbarmessage" placeholder="Message" required></textarea>
<label for="contactButton">
<button type="button" class="contactButton" id="submit_announcement">Add Announcement</button>
</label>
</form>
<?php
if ($announcements_stmt = $con->prepare("SELECT * FROM announcements")) {
$announcements_stmt->execute();
$announcements_stmt->bind_result($announcements_id, $announcements_user_id, $announcements_messages, $announcements_date);
if (!$announcements_stmt) {
throw new Exception($con->error);
}
$announcements_stmt->store_result();
$announcements_result = array();
?>
Current Announcements
<table>
<tr>
<th>ID</th>
<th>Username</th>
<th>Message</th>
<th>Date</th>
</tr>
<?php
while ($row = $stmt->fetch()) {
?>
<tr>
<td><?php echo $announcements_id; ?></td>
<td><?php echo $announcements_username; ?></td>
<td><?php echo $announcements_messages; ?></td>
<td><?php echo $announcements_date; ?></td>
</tr>
</table>
<?php
}
}
}
}
catch (Exception $e)
{
echo "Error: " . $e->getMessage();
}
?>
</div>
<div id='dues'>League Dues</div>
</div>
You have an error when building the announcement-table.
The closing </table> tag is inside the while loop, so the html will be screwed up, making everything after the closed table disappear.
So change the while loop to:
....
<?php
while ($row = $stmt->fetch()) {
?>
<tr>
<td><?php echo $announcements_id; ?></td>
<td><?php echo $announcements_username; ?></td>
<td><?php echo $announcements_messages; ?></td>
<td><?php echo $announcements_date; ?></td>
</tr>
<?php
}
?>
</table>
<?php
....
Anyway, I recommend to build your html first in a variable and echo it out later alltogether. That makes cleaner code and reduces risk of inconsitency of html tags. When using with HEREDOC you even don't have to bother about quotes.
In your case that could for example look like that:
<?php
$table_head = <<<EOT
<tr>
<th>ID</th>
<th>Username</th>
<th>Message</th>
<th>Date</th>
</tr>
EOT;
$table_content = "";
while ($row = $stmt->fetch()) {
$table_content.= <<<EOT
<tr>
<td>$announcements_id</td>
<td>$announcements_username</td>
<td>$announcements_messages</td>
<td>$announcements_date</td>
</tr>
EOT;
}
$announcement_table = "<table>".$table_head.$table_content."</table>";
echo $announcement_table;
