i create rand funtion for generating random value and concatenate with other value and show in the text field through ajax before insert this value. but here how can i check this random generating value is exists or not in database before inserting this value in database.if value is exists then again generate rand function value and again concatenate this and show the value in textbox. how can i do this? my code is below

I suggest to use md5 function and/or time() function such as:
$rand = md5(time() + rand(100000,999999));
Your updated code should be:
$name1 = $_POST['name'];
$year1 = $_POST['year'];
$course1 = $_POST['course'];
$branch_name1 = $_POST['branch_name'];
$name2 = substr($name1,0,3);
$name = strtoupper($name2);
$year = substr($year1,-2);
$branch_name = strtoupper(substr($branch_name1,0,3));
$course2 = substr($course1,0,3);
$course = strtoupper($course2);
$rand = md5(time() + rand(100000,999999));
$roll = $branch_name.$name.$course.$year.$rand;
echo $roll;
This solution provide unique value. You can use also uniqid() function. Also remember to set as unique the database field.
Another solution is to keep roll creation login in a function and create another function to check if the roll exists or not. Your responsibility to check if other rolls are store in the db or in a text file, ...
function calculateRoll()
{
$name1 = $_POST['name'];
$year1 = $_POST['year'];
$course1 = $_POST['course'];
$branch_name1 = $_POST['branch_name'];
$name2 = substr($name1,0,3);
$name = strtoupper($name2);
$year = substr($year1,-2);
$branch_name = strtoupper(substr($branch_name1,0,3));
$course2 = substr($course1,0,3);
$course = strtoupper($course2);
$rand = rand(100000,999999);
return $branch_name.$name.$course.$year.$rand;
}
function isValidRoll($roll) {
$result = mysql_query("SELECT count(*) as total FROM student WHERE roll = '$roll'")
or die("Query not valid: " . mysql_error());
$data = mysql_fetch_assoc($result);
return $data['total'] == 0;
}
$validRoll = false;
$roll = calculateRoll();
while (!$validRoll) {
if (isValidRoll($roll)) {
$validRoll = true;
} else {
$roll = calculateRoll();
}
}
when ever you save the data of the form store rand function value too means in second time you can retrieve the rand function value and compare with current rand function generating value.

I am trying to build a way for a user to be able to create an article, if they want, with a button they can add an input for a text, a file input etc.
I want to send this form with JavaScript vanilla (training)
so what I do in my js is that I loop into my different added input then I append them to formData
and send this formData to my controller to treat it and add it to my database.
Problem is that by iterating my input when I append my input into formData I have to add the index
so when I send it and print_r my post
I get like:
text01
text02
text03 etc.
it would be fine if it was only these input that I wanted to send but in my post I have other inputs which are sent the same way so I get like
title01
paragraphe01
title02
paragprahe02
the problem will be when I want to query to add the data to my database I would have to bind all of these to my query, but of course I can't make 50 lines of
bind('text01', $text01)
I don't think it would be a nice way to do it
so I am looking for a way to be able to query all of these data I thought of maybe a way getting only the paragraphs indexes and putting them in an array containing only paragraphs then forEach() everything.
another array for another input etc. but I can't find a way to do it, is it even possible
so here is my code

and this is the response I get in my console.log maybe it will be more clear
thank you
Little edit so i managed to make an array for each of my input
array paragraphe for paragraphes
note for notes etc...
i changed this
for(i = 0; i <= images.length; i++) {
let uFiles = images[i];
if (uFiles) {
formData.append("name" + i, uFiles.files[0]);
}
}
for(let i = 0; i < paragraphe.length; i++) {
let paragraphes = paragraphe[i].value;
if (paragraphes) {
formData.append("paragraphe"+i,paragraphes);
}
}
for(let i = 0; i < note.length; i++) {
let notes = note[i].value;
if (notes) {
formData.append("note" + i, notes);
}
}
by this
for(i = 0; i <= images.length; i++) {
let uFiles = images[i];
if (uFiles) {
formData.append("name[]" + i, uFiles.files[0]);
}
}
for(let i = 0; i < paragraphe.length; i++) {
let paragraphes = paragraphe[i].value;
if (paragraphes) {
formData.append("paragraphe[]"+i,paragraphes);
}
}
for(let i = 0; i < note.length; i++) {
let notes = note[i].value;
if (notes) {
formData.append("note[]" + i, notes);
}
}
but here's the problem
i can't find a way to foreach multiple array in php to add them to my database
this is the response result i get in my console now
reponse2
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 ...
{
$MR = $_GET['MR']; // Set the variables.
$PR = $Pres_Rev;
}
else // If not, select the maximum (latest) Manager Review Date.
{
$getmr = "select max(STR_TO_DATE(Manager_Review_Date, '%m/%d/%Y')) as 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">

This is my test url: php poll. Please let me know if you need more details. I am not sure which code is needed to be shown here. Thankyou so much for helping.
Try this --

I just want to ask if how to merge this two array from all id value and data-rate value on my list order? there is too many ul li, so i need to get them all and store it into array.
this is my code in javascript:
var h = [];
$("ul.reorder-photos-list li").each(function() { h.push($(this).attr('id').substr(9)); });
var x = [];
$("ul.reorder-photos-list li").each(function() { x.push($(this).attr('data-rate').substr(9)); });
$.ajax({
type: "POST",
url: "order_update.php",
data: {
ids: " " + h + "",
rate: " " + x + ""
},
success: function(html)
{
window.location.reload();
/*$("#reorder-helper").html( "Reorder Completed - Image reorder have been successfully completed. Please reload the page for testing the reorder." ).removeClass('light_box').addClass('notice notice_success');
$('.reorder_link').html('reorder photos');
$('.reorder_link').attr("id","");*/
}
});
and this is my html code:
<li id="image_li_<?php echo $row['id']; ?>" class="ui-sortable-handle">
<input id="rate" type="text" value="<?= $row['rate']?>" data-rate="<?php echo $row['rate']; ?>" >
and then in my order_update.php this is my code.
$idArray = explode(",",$_POST['ids']);
$rateArray = explode(",",$_POST['rate']);
$ids = array();
foreach ($idArray as $id) {
$ids[] = $id;
}
$rates = array();
foreach ($rateArray as $rate) {
$rates[] = $rate;
}
$n = 0;
$orderArray = array();
while( $n <= count($idArray) )
{
$orderArray[] = array("id" => $ids[$n], "data" => $rates[$n]);
$n++;
}
and this is my insert query from orderArray
function updateOrder($orderArray){
$count = 1;
foreach ($orderArray as $array){
$update = mysqli_query($this->connect,"UPDATE `test` SET `order` = $count, `rate`=$array[rate] WHERE id = $array[id]");
$count ++;
}
return true;
}
hope someones helps me. :)thanks in advance!
When setting up your data, you don't need to have multiple loops. You can loop through the data once:
var dataArray = [];
$("ul.reorder-photos-list li").each(function() {
var el = $(this),
input = el.children(':input'); // This gets the input decendent of the li
// When adding one item at a time to an array, array[array.length] = item is better
dataArray[dataArray.length] = {
id: el.attr('id').substr(9),
rate: input.val(),
};
});
$.ajax({
type: "POST",
url: "order_update.php",
data: { items: dataArray }, // items gives the PHP something to use as a key in the POST data
success: function(html) {...}
});
Your PHP will look like this:
// The data passed from the Ajax call is already an array
$itemsArray = $_POST['items'];
// Your function to process the array
function updateOrder($orderArray) {
foreach ($orderArray as $index => $array) {
// $index will already have a count, you need to +1 because it's 0-based
mysqli_query($this->connect, "UPDATE `test` SET `order` = " . ($index + 1) . ", `rate`=" . $array['rate'] . " WHERE id = " . $array['id']);
}
return true;
}
var rates;
$("ul.reorder-photos-list li").each(function() {
rates.id.push($(this).attr('id').substr(9));
rates.rate.push($(this).attr('data-rate').substr(9));
});
This will create your JSON object of h/x pairs.
$.ajax({
type: "POST"
, url: "order_update.php"
, data: { JSON.stringify(rates); }
, success: function(html) {
window.location.reload();
/* $("#reorder-helper").html(
* "Reorder Completed - Image reorder have been successfully completed.
* Please reload the page for testing the reorder."
* ).removeClass('light_box').addClass('notice notice_success');
* $('.reorder_link').html('reorder photos');
* $('.reorder_link').attr("id","");
*/
}
});
This should fix your call to send the correct data.
Your PHP side is going to want to have something similar to this:
if(isset($_POST['rates'])) {
$ratesString = $_POST['rates'];
$rates = json_decode($ratesString);
}
// Do other things with $hx`
Your insert query is off, too. You need to declare each value as a variable or your compiler is going to hate your PHP, too. You also have some unnecessary quotes in your query.
function updateOrder($orderArray){
$count = 1;
foreach ($orderArray as $array){
$rate = $array['rate'];
$id = $array['id'];
mysqli_query($this->connect,"UPDATE test SET order = $count, rate = '$rate' WHERE id = '$id'");
$count ++;
}
return true;
}
For your HTML, I think this is what you were going for, but not sure since it's not really explained all that well...Feel free to comment on your intentions.
<ul>
<?php foreach($orderArray as $array) : ?>
<li id="image_li_<?php echo $array['id']; ?>" class="ui-sortable-handle">
<input id="rate" type="text" value="<?php echo $array['rate']?>" data-rate="<?php echo $array['rate']; ?>" ></li>
<?php endforeach; ?>
</ul>
Hope this helps.

I got the code now. thanks for your help guys!
var h = [];
$("ul.reorder-photos-list li").each(function() { h.push($(this).attr('id').substr(9)); });
var x = [];
$("input").each(function() { x.push($(this).val()); });
$.ajax({
type: "POST",
url: "order_update.php",
data: {ids: " " + h + "",rate: " " + x + ""},
/*data: { items: dataArray },*/
success: function(html)
{
...
}
});
In Php side:
$idArray = explode(",",$_POST['ids']);
$rateArray = explode(",",$_POST['rate']);
$ids = array();
foreach ($idArray as $id) {
$ids[] = $id;
}
$rates = array();
foreach ($rateArray as $rate) {
$rates[] = $rate;
}
$n = 0;
$orderArray = array();
while( $n <= count($idArray) )
{
$orderArray[] = array("id" => $ids[$n] , "rate" => $rates[$n]);
$n++;
}
$db->updateOrder($orderArray);
function updateOrder($orderArray){
$count = 1;
foreach ($orderArray as $array){
mysqli_query($this->connect, "UPDATE `test` SET `morder` = " . $count . ", `mtoursrate`=" . $array['rate'] . " WHERE id = " . $array['id']);
$count ++;
}
return true;
}
