I cant find the error from my code,took me hours trying to figure it out but still cant make it work.
I've checked on the browser console and it shows as ascreenshot below :
Here's my code :
<?php
session_start();

include "koneksi.php";

I want to show a sweetalert after clicking the set button but it won't function. This is my index page and the set button can function but it won't show the sweet alert. what might be the problem and what should I do?

This is my code on the edit part and this works, only the alert won't show up.
updataStatus.php
<?php
require_once "connection.php";
if(isset($_POST['but_update'])){
if(isset($_POST['update'])){
foreach($_POST['update'] as $id){

$_SESSION['success'] = "YOUR DATA UPDATED";
header('Location: tracking.php');
}else{
$_SESSION['success'] = "YOUR DATA IS NOT UPDATED";
header('Location: tracking.php');
}
}
}
}
}
?>
considering you have not implemented another function to call sweetalert; by default, it should be Swal.fire({}) not just swal({})

Can someone help me on pagination syntax for php webpage. I have a set a pagination code to display 20 records per page. The records are displaying based on 'start date' and 'end date'.
The issue is, it works on page 1 but when I click on page 2 in pagination then it won't work. I assume the values of $_POST['startdate'] and $_POST['enddate] are not forwarding on page2.

$_POST superglobal variable is populated by PHP when a POST HTTP request is processed. This is the case on the request for page 1.
However, your go2page() function is mutating location.href, which generates a GET HTTP request, and so does pagination links.
You should append your startdate and enddate params to the pagination URLs, to forward your params to the next/previous requests :
qm.php?page=<YOUR-PAGE-NUMBER>&startdate=<YOUR-START-DATE>&enddate=<YOUR-END-DATE>';
And use $_GET['startdate'] and $_GET['enddate] to retrieve those when processing GET requests.
More about $_POST https://www.php.net/manual/en/reserved.variables.post.php
More about GET AND POST HTTP requests : https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods
There's an error in your isset($_POST['Search'])
your code:
if(isset($_POST['Search'])){
$startdate1 = $_POST['startdate'];
echo "Start date : ".$startdate1", ";
$enddate1 = $_POST['enddate'];
echo "End date : ".$enddate1;
}
possible working solution:
if(isset($_POST['Search'])){
$startdate1 = $_POST['startdate'];
echo "Start date : ".$startdate1.", ";
$enddate1 = $_POST['enddate'];
echo "End date : ".$enddate1;
}
Though I didn't try it yet, but I assume this is the cause, pagination in page2 will not work since the code is not executed after the error which is the pagination for page2.
EDIT: The . fixes things.
echo "Start date : ".$startdate1", ";
is different than
echo "Start date : ".$startdate1.", ";
Add values of your $_POST inside links and use them as $_GET so you would use both.
$startdate1=$enddate1=null; //to hide notice
if(isset($_POST['Search'])){
$startdate1 = $_POST['startdate'];
echo "Start date : ".$startdate1.", ";
$enddate1 = $_POST['enddate'];
echo "End date : ".$enddate1;
} else if (!empty($_GET['startdate']) && !empty($_GET['enddate'])){
$startdate1 = $_GET['startdate'];
echo "Start date : ".$startdate1.", ";
$enddate1 = $_GET['enddate'];
echo "End date : ".$enddate1;
}
$pagLink .= "<li><a href='qm.php?page=".($k+$i)."&startdate=".startdate1."&enddate=".$enddate1."'>".($k+$i)."</a></li>";
For your need:
$pagLink = "";
if($pn>=2){
echo "<li><a href='qm.php?page=1&startdate=".startdate1."&enddate=".$enddate1."'> << </a></li>";
echo "<li><a href='qm.php?page=".($pn-1)."&startdate=".startdate1."&enddate=".$enddate1."'> < </a></li>";
}
for ($i=-4; $i<=4; $i++) {
if($k+$i==$pn)
$pagLink .= "<li class='active'><a href='qm.php?page=".($k+$i)."&startdate=".startdate1."&enddate=".$enddate1."'>".($k+$i)."</a></li>";
else
$pagLink .= "<li><a href='qm.php?page=".($k+$i)."&startdate=".startdate1."&enddate=".$enddate1."'>".($k+$i)."</a></li>";
};
echo $pagLink;
if($pn<$total_pages){
echo "<li><a href='qm.php?page=".($pn+1)."&startdate=".startdate1."&enddate=".$enddate1."'> > </a></li>";
echo "<li><a href='qm.php?page=".$total_pages."&startdate=".startdate1."&enddate=".$enddate1."'> >> </a></li>";
}
That would help you to move dates to next page.
You need to set it to all paging links. Also you can make extra if statement to not pass empty GET
EDIT:
As I already told: You need to set it to all paging links. Also you can make extra if statement to not pass empty GET (that includes javascript)
function go2Page()
{
var pn = document.getElementById("pn").value;
pn = ((pn><?php echo $total_pages; ?>)?<?php echo $total_pages; ?>:((pn<1)?1:pn));
window.location.href = 'teztz.php?page='+pn+'&startdate=<?=startdate1;?>&enddate=<?=$enddate1;?>';
}
Trying to load php results (from a different page) into a div on same page on link clicked
I have tried following the answer in here
But this didn't work for me. Below is what i have tried
price.php
<div class="pricepop"></div>
<?php
$sql = $db->prepare("SELECT * FROM commodityprices");
$result = $sql->execute();

$unit = $row['unit'];
$iprice = $row['iprice'];
$lprice = $row['lprice'];
$irate = $row['irate'];
$lrate = $row['lrate'];
$terms = $row['cterms'];
$asat = date('d/M/Y');
$market = $row['market'];
echo '<tr>
<td>'.$name.'</td>
<td>'.$unit.'</td>';
if ($irate == "Down")
{
echo '
<td style="background: #ef5a66; color: #fff"><i class="fa fa-caret-down"> </i> '.$iprice.'</td>';
}
else

</td>
</tr>';
}
pricedetails.php
<?php
$priceId = $_GET['id'];
$sql = $db->prepare("SELECT * FROM commodityprices WHERE id = ?");
$sql->bindParam(1, $priceId, SQLITE3_INTEGER);
$result = $sql->execute();
while ($row = $result->fetchArray(SQLITE3_ASSOC))
{
$id = $row['id'];
$name = $row['name'];
$iprice = $row['iprice'];
$lprice = $row['lprice'];
$lrate = $row['lrate'];
$terms = $row['cterms'];

}
echo '<td>'.$asat.'</td>
<td>'.$market.'</td>
<td class="comprice">'.$priceperbags.'</td>
</tr>';
}
The JavaScript
$(document).ready(function() {
$(".comprice").on("click", function (e) {
e.preventDefault();
$(".pricepop").load("pricedetails.php");
});
});
When i click on the view more link in price.php the results in pricedeatils.php is supposed to display in the .pricepop div (which is in price.php page) but when i click currently the .pricepop is blank. Please how do i solve this issue? Thanks.
Your code isn't loading the correct url. Modified so id parameter is part of the url.
Use this js script instead.
$(document).ready(function() {
$(".comprice").on("click", function (e) {
e.preventDefault();
$(".pricepop").load($(this).attr('href'));
});
});

I validate the field and the inserting process into database:
function registerProcess(){
$con = mysqli_connect(DATABASE_HOST, DATABASE_USER, DATABASE_PASSWORD, DATABASE_NAME);
global $process;
// To protect MySQL injection (more detail about MySQL injection)
$process = cleanInputData($process);
$process = mysqli_real_escape_string($con, $process);
//query result
$result = insertNewProcess(NULL,$process,$_SESSION['login_user'],1);
// Check result
if (!$result) {
$msg2= "Process is already added. You cannot add same process twice!";
echo $msg2;
die('Invalid queryyyy: ' . mysqli_error($con));
}
// the message
$msg = "Process is added!";
// use wordwrap() if lines are longer than 70 characters
echo "<script>var registerStr = 'Process Is Added';</script>";
//echo "<meta http-equiv='refresh' content='0'>";
}
function verifyFormFields(){
global $process;
if(empty($process)){
return "<p id ='err'>Please Input Process</p>";
}
else return "";
}
Also I use javascript to call pop up window and make table paginated:
<script type="text/javascript">
(function() {
$(document).foundation();
});
function callShowAlert()
{
$('#registerModal').foundation('reveal', 'open');
}
function popUpNo()
{
$('#registerModal').foundation('reveal', 'close');
location.href = 'process.php';
}
var testVal = 0;
</script>
<script>
$(document).ready(function() {
$('table.paginated').each(function() {
var currentPage = 0;
var numPerPage = 5;
var $table = $(this);
$table.bind('repaginate', function() {
$table.find('tbody tr').hide().slice(currentPage * numPerPage, (currentPage + 1) * numPerPage).show();
});
$table.trigger('repaginate');
var numRows = $table.find('tbody tr').length;
var numPages = Math.ceil(numRows / numPerPage);
var $pager = $('<div class="pager"></div>');
for (var page = 0; page < numPages; page++) {
$('<span class="page-number"></span>').text(page + 1).bind('click', {
newPage: page
}, function(event) {
currentPage = event.data['newPage'];
$table.trigger('repaginate');
$(this).addClass('active').siblings().removeClass('active');
}).appendTo($pager).addClass('clickable');
}
$pager.insertBefore($table).find('span.page-number:first').addClass('active');
});
} );
</script>
it works perfect, I got popup window and system inserts record to database but only if there is only input field and submit button. When I put table it doesnt work. System does not reload and not insert record into database. Why?
So I solved this problem by simply putting table after form:
<div class="inner">
<form id="reguserform" method="post" action="process.php#err" style="margin-top:40px;">
<?php
$res = verifyFormFields();
?>
<!-- Username field -->
<input type="text" class="input name" placeholder="Process name (required)" name="process" required/>
<!--<label class="tooll tool1">- No special Characters except _<br>- Character Limit: 4 to 20<br>- Username must be Unique</label>-->
<center><input type="submit" class="button small" name="submit" value="Create Process"/></center>
<div id="registerModal" class="reveal-modal small" data-reveal aria-labelledby="modalTitle" aria-hidden="true" role="dialog" data-options="close_on_background_click:false">
<h2 id="modalTitle">Success!</h2>
<div>
<div id="testRegister" style="font-weight: 400;font-size: 1.5em; font-family: 'Raleway', Arial, sans-serif;"></div>
<div class="right">
Ok
</div>
</div>
</div>
<?php
if($count == 1)
{
if($res=="")
{
registerProcess();
echo"<script>document.getElementById('testRegister').innerHTML=registerStr;callShowAlert();</script>";
}
else{
echo "
<a style='color:red';>
$res
</a>
";
}
}
?>
</form>
<center><table class="paginated">
<?php
$result = getProcessData();
if (mysqli_num_rows($result) > 0)
{
echo '
<thead>
<tr>
<th>Process</th>
<th>Created By</th>
</tr>
</thead>';
}
$count = 0;
if (mysqli_num_rows($result) > 0)
while($row = mysqli_fetch_array($result))
{
$process = $row['theme_name'];
$createdBy = $row['createby'];
echo '
<tbody>
<tr valign="top">
<td>' .$process. '</td>
<td>' .$createdBy. '</td>
</tr>
</tbody>';
$count++;
}
?>
</table></center>
</div>
So as I got it, table cannot be updated before from.
I'm trying add to cart using CodeIgniter and it is working fine but, when I want to do the same through ajax its getting some problem. Can you please look at my codes and tell me where do I get some mistakes? I'm confused how to use ajax to call the add function of the controller . What should I add or do in the ajax code to make this function work?

$this->cart->destroy();
}else{
// Destroy selected rowid in session.
$data = array(

// Update cart data, after cancle.

}
// This will show cancle data in cart.
redirect('shopping');
}
function update_cart(){
// Recieve post values,calcute them and update
$cart_info = $_POST['cart'] ;
foreach( $cart_info as $id => $cart)

$rowid = $cart['rowid'];
$price = $cart['price'];
$amount = $price * $cart['qty'];
$qty = $cart['qty'];
$data = array(

'price' => $price,
'amount' => $amount,
'qty' => $qty

$this->cart->update($data);

}

How should I apply this code to ajax?
Thanks for the help.
it's not necessary to use "success:"
However if you want to check error or debug
1) press F12 on Browser to open Developer Mode
2) do action (add cart)
3) on tab "Network" find your ajax request and see your error
Modify your add() function as follows:
function add(){
$insert_data = array('k1' => 'v1', 'k2' => 'v2');
$success = $this->cart->insert($insert_data);
if($success){
$res = array('status' => 200, 'msg' => 'success', 'somekey' => 'somevalue');
}else{
$res = array('status' => 500, 'msg' => 'database err');
}
echo json_encode($res);
}
Now the add() function has responded the ajax request with some json-formated data, you can parse the response data in javascript. The (success:) function should be like this:
function(response) {
if (response){
var res = JSON.parse(response);
if(res.status == 200){
window.location.href="http://127.0.0.1/codeigniter_cart2/index.php/shopping";
}else{
//error handler
alert(res.msg);
}
}else{
alert('sorry');
}
});
function __construct(){
parent::__construct();
$this->load->library(array('session','cart'));
$this->load->library('');
$this->load->helper('url');
$this->load->database();
}
public function product_list(){
$this->db->select('*');
$this->db->from('product');
$this->db->order_by('product_id','desc');
$rs = $this->db->get();
return $rs->result_array();
}
public function product_byId($pid){
$this->db->select('*');
$this->db->from('product');
$this->db->where('product_id',$pid);
$rs = $this->db->get();
return $rs->row_array();
}
