The following code creates two folders, one with the $folderName and one with the $date with the files uploaded. If I change the $folderName to something static like "uploadingFolder" it creates the folder with the files uploaded.
How can I get the naming convention for the folder I want uploaded with its contents: firstname lastname date.
$formdata = json_decode(file_get_contents("php://input"),true);
$fname = array_column($formdata, 'firstname');
$lname = array_column($formdata, 'lastname');
$date = date('d-m-Y');
$folderName = $fname[0].$lname[0].$date;
//$folderName = "uploadingFolder";
mkdir('uploads/'.$folderName, 0777, true);
$total = count($_FILES['files']['name']);
for( $i=0 ; $i < $total ; $i++ ) {
$tmpFilePath = $_FILES['files']['tmp_name'][$i];
$newFilePath = "uploads/".$folderName."/".$_FILES['files']['name'][$i];
if(move_uploaded_file($tmpFilePath, $newFilePath)){
echo "upload successful ";
} else {
echo "error uploading files ";
}
}

Everyone.
I got some good help a couple of days ago, so I'm hoping that someone can show me where I'm going wrong here. Basically, what I'm trying to do is update a MySQL database in the background when a user clicks a button. The form is a series of records, and the records have common field names (ID, DSA_Number, Manager_Review, etc.) Right now, the code doesn't even seem to return success or failure messages.
Here's the script on the main page:
<script>
$(document).ready(function(){
$("#button").click(function(){
var DDD_Number=$("#DDD_Number").val();
var Manager_Review=$("#Manager_Review").val();
var RID=$("#RID").val();
var Services=$("Services").val();
var Dues_List=$("Dues_List").val();
var ID=$("ID").val();
var myrid=$("myrid").val();
var Manager_Comments=$("Manager_Comments").val();
var President_Comments=$("President_Comments").val();
var dataTosend='?DDD_Number='+DDD_Number+'&Manager_Review='+Manager_Review+'&RID='+RID+'&Services='+Services+'&Dues_List='+Dues_List+'&Manager_Comments='+Manager_Comments+'&President_Comments='+President_Comments;
$.ajax({
type: "GET",
url:'baseupdater-test.php' + dataTosend,
data:dataTosend,
async: true,
success:function(data){
document.getElementById('stuffhere').innerHTML.text = "Success.";
document.getElementById('stuffhere').innerHTML.text = data;
},
error: function(data){
document.getElementById('stuffhere').innerHTML.text = "Failure.";
}
});
});
</script>
Here's the code that draws the rows on the table:
<?php
/* This code writes the rows in the table for baserecord.php */
$n = 0;
$o = $n + 1;
$firstday = date('m/1/Y');
if(isset($_GET['MR'])) // If $_GET['MR'] is set ...
{

$PR = $Pres_Rev;
}
else // If not, select the maximum (latest) Manager Review Date.
{

I've tried serializing the form, and I haven't had any success there. Any suggestions would be greatly welcome. Sorry for the long post, but I'm just not sure where the error is at this point.
Your code
var data= [DDD_Number,Manager_Review,RID,Services,Dues_List,ID,myrid,Manager_Comments,President_Comments];
var datatosend = JSON.stringify(data);
$.ajax({
type: "GET",
url:'baseupdater-test.php',
data:dataTosend,
async: true,
success:function(data){
document.getElementById('stuffhere').innerHTML.text = "Success.";
document.getElementById('stuffhere').innerHTML.text = data;
},
error: function(data){
document.getElementById('stuffhere').innerHTML.text = "Failure.";
}
});
As i can see you are trying to send the data twice, first through url and second with the ajax data method please fix that i think its a wrong approach to do that you should send it only once.
And moreover you must convert the data into json format to make the ajax request work
and now what's happening is as your data is not in the correct format your code must be stuck at the data in ajax you can see it in console the ajax request would not show you any value passing to another and that is the main reason the Success or Failure are not being show.
I am trying to define my php variable for my php poll vote. I want to echo "Have a good day!" if the vote in for "Hello" is more that "Others" else echo "Have a good night!". :
if ($votePercent < $votePercent) {
echo "Have a good day!";
} else {
echo "Have a good night!";
}
?>
How to I define the variable $votePercent?
<div class="container">
<h3><?php echo $pollResult['poll']; ?></h3>
<p><b>Total Votes:</b> <?php echo $pollResult['total_votes']; ?></p>
<?php
if(!empty($pollResult['options'])){ $i=0;
//options bar color class array
$barColorArr = array('azure','emerald','violet','yellow','red');
//generate option bars with votes count
foreach($pollResult['options'] as $opt=>$vote){
//calculate vote percent
$votePercent = round(($vote/$pollResult['total_votes'])*100);
$votePercent = !empty($votePercent)?$votePercent.'%':'0%';
//define bar color class
if(!array_key_exists($i, $barColorArr)){
$i = 0;
}
$barColor = $barColorArr[$i];
?>
<div class="bar-main-container <?php echo $barColor; ?>">
<div class="txt"><?php echo $opt; ?></div>
<div class="wrap">
<div class="bar-percentage"><?php echo $votePercent; ?></div>
<div class="bar-container">

I have problem when a visitor clicks on a submenu and the link opens in a new page, so I want to keep that submenu active on that page.
I have css class active and javascript for opening it, what I need is to make it with php to be active.
This is UL with class:
This is my code. Can it be done with php or with javascript.
<ul>
<?php
$qKategori = ("SELECT * FROM kategori WHERE kprind = 0");
$rKategori = mysqli_query($dbc, $qKategori);
if ($rKategori) {
while ($exKat = mysqli_fetch_array($rKategori, MYSQLI_ASSOC)){
$emrikategorise = $exKat['kemri'];
$idkategori = $exKat['kid'];
$idprind = $exKat['kprind'];
?>
<li><?=$emrikategorise;?>
<ul>
<?php
$qPrind = ("SELECT * FROM kategori WHERE kprind = '".$idkategori."'");
$rPrind = mysqli_query($dbc,$qPrind);
while($prind = mysqli_fetch_array($rPrind)) {
?>
<li><?=$prind['kemri']?> </li>
<?php
}
mysqli_free_result($rPrind);
?>
</ul>
</li>
<?php }
mysqli_free_result($rKategori);
}
?>
</ul>
You can see menu on the left in The website is www.sitimobil.mk
You probably will need to build the array before outputting to be able to determine which menus should be active. You can also combine it with an optimization of the query to not have to do 1 query per category.
Something like:
$active = isset($_GET['kid'] ? $_GET['kid'] : -1;
$tree = array();
$list = array();
$qKategori = ("SELECT * FROM kategori ORDER BY kprind");
$rKategori = mysqli_query($dbc, $qKategori);
if ($rKategori) {
while ($exKat = mysqli_fetch_array($rKategori, MYSQLI_ASSOC)){
$id = $exKat['kid'];
//To prevent numerical array with unused space
$name = 'kategori'.$exKat['kid'];
$list[$name] = $exKat;
//Calculate depth to see if the menu is a sub..sub..sub menu etc.
$parent = $list[$name]['kprind'];
if($parent == 0) {
$list[$name]['depth'] = 0;
$list[$name]['childCount'] = 0;
}
else {
$list['kategori'.$parent]['childCount']++;
$list[$name]['depth'] = $list['kategori'.$parent]['depth']+1; //Increment
}
if($id == $active) {
$list[$name]['active'] = true;
while($parent != 0) {
$parentName = 'kategori'.$parent;
$list[$parentName]['active'] = true;
$parent = $list[$parentName]['kprind'];
}
}
else
$list[$name]['active'] = false;
}
mysqli_free_result($rPrind);
//Once we have that we can output the results...
function output_menu($list, $parent = 0, $active = false)
$activeClass = $active ? ' class="active"' : '';
echo '<ul'.$activeClass.'>';
foreach($list as $row){
if($row['kprind'] != $parent) continue;
$link = $row['kprind'] == 0 ? '#' : 'kategori.php?kid='.$row['kid'];
echo '<li>'.$row['kemri'].'';
if($row['childCount'] > 0)
output_menu($list, $row['kprind'], $row['active']);
echo '</li>';
}
echo '</ul>';
}
output_menu($list);
}
This is still a bit rough but should do the trick. It can probably be optimized so that we don't have to go through the list too many times but has the benefit of not having to request too many calls to the database. That should result in a lighter workload for the DB and faster output.
I'm having difficulty iterating through records while scrolling window. My initial thought was to load enough records to fit on screen then load an additional set when window scrolled to bottom. I've tried using session / variables to pass some counter to a function, no luck. The code below returns enough records to fit window height but with 0,10 limit. What would be a simple method to resolve this?
Another question is should I use LIMIT or ID > + LIMIT on the Mysql query?
$(function(){
setInterval(function(){
var totalHeight, currentScroll, visibleHeight;
if (document.documentElement.scrollTop)
{ currentScroll = document.documentElement.scrollTop; }
else
{ currentScroll = document.body.scrollTop; }
totalHeight = document.body.offsetHeight;
visibleHeight = document.documentElement.clientHeight;
if (totalHeight <= currentScroll + visibleHeight )
{
$.get('infinite_pull.php', function(data) {
$('body').append(data);
//alert('Load was performed.');
});
}
else
{
$('.dd').css('background-color','white');
}
}
, 100);
});
PHP
<?php
session_start();
mysql_connect('localhost','root','');
mysql_select_db('project5');
$query = "select user_email from users limit 0,10;";
$results= mysql_query($query);
while($row = mysql_fetch_array($results)){
echo $row['0'] . '<br/>';
}
?>
to call the php file multiple times sound bad,
all that overhead proberly worse then getting all at once.
can't you just calculate how many you need, and ask for that number?
<?php
$from = (int) $_GET['from'];
$count = (int) $_GET['count'];
mysql_connect('localhost','root','');
mysql_select_db('project5');
$query = "select user_email from users limit {$from},{$count};";
$results= mysql_query($query);
while($row = mysql_fetch_array($results)){
echo $row['0'] . '<br/>';
}
?>
i also think you should add an order by, to be sure the result always gets in the same order.
Use LIMIT, which combines a offset (1st param) and number of rows to get (2nd param). Here's a short example of pagination that get's the 7th page of a 100 numbers 7 at a time.
<?php
$arr = array();
for ( $x = 0; $x < 100; $x += 1 ) {
$arr[] = $x;
};
$page = 7;
$per_page = 7;
$current_page = 1;
for ( $z = 0; $z < count( $arr ); $z += 1 ) {
if ( 0 === ( $z % $per_page ) ) {
$current_page += 1;
}
if ( $current_page === $page ) {
$num_results = $current_page * $per_page;
$query = "select user_email from users limit {$num_results},{$per_page};";
echo "value $z on page $page via $query \n";
}
}
?>
Output:
$ php pagination.php
value 35 on page 7 via select user_email from users limit 49,7;
value 36 on page 7 via select user_email from users limit 49,7;
value 37 on page 7 via select user_email from users limit 49,7;
value 38 on page 7 via select user_email from users limit 49,7;
value 39 on page 7 via select user_email from users limit 49,7;
value 40 on page 7 via select user_email from users limit 49,7;
value 41 on page 7 via select user_email from users limit 49,7;
