Does "NO POST" mean "no GET" as well? Otherwise you could put your retrieval script in a different file and call that with jQuery.get or XMLHttpRequest.

Update php SQL when checkbox check (no submit button)

I am pulling data out of a database and displaying in a table. I would like my checkbox, when checked/unchecked, to auto-update the value in the database without using a submit button to trigger the action. I'm new to AJAX and tried to adapt some code. I cannot get it to work. One major thing I don't understand is what '#state_span' is for?
Data Page (HTML)
$sql = "SELECT * FROM Orders ORDER BY " .$order;
$myData = mysqli_query($dbconnect, $sql);
while ($record = mysqli_fetch_array($myData)){
if ($record['Sent'] == 0) {
$sent = "";
} else {
$sent = "checked";
}
if ($record['Paid'] == 0) {
$paid = "";
} else {
$paid = "checked";
}
echo "<tr>";
echo '<td class="MenuLeft">' . $count . "</td>";
echo '<td class="MenuMid">' . $record['Name'] . "</td>";
echo '<td class="MenuRight"><input type="checkbox"
name="Sent"
id="'. $record['ID'] .'"
class="ChkSwitch"' . $sent . ' ></td>';
echo '<td class="MenuRight"><input type="checkbox"
name="Paid"
id="'. $record['ID'] .'"
class="ChkSwitch"' . $paid . ' ></td>';
echo "</tr>";
echo '<script>
$(document).ready(function() {
$(".ChkSwitch").click(function() {
var id = this.id;
var col = this.name; //Tell us what column to update
var state = this.checked ? 1 : 0;
$("#state_span").load("ChkUpdate.php?d="+id+"&col="+col+"&state="+state);
}
}
</script>
';
PHP
$id = $_GET['id'];
$state= $_GET['state'];
$col= $_GET['col'];
include("dbconnect.php");
$query = "UPDATE Orders SET '$col' = '$state' WHERE ID = '$id' ";
mysqli_query($dbconnect, $query);

How to put validation on a dynamic dropdown when inserting in PHP?

I'm constructing a survey and I have a textbox that generates dynamic dropdowns based on user input which displays the same data.
This is the script
<script>
function load_questions(){
var xmlhttp=new XMLHttpRequest();
xmlhttp.open("GET","ajax.php??main=1&subcategory="+document.getElementById("subcategorydd").value +"&cnt="+document.getElementById("q_num").value,false);
xmlhttp.send(null);
document.getElementById("question").innerHTML=xmlhttp.responseText;
}
function checkValues() {
_values = [];
$('.form-control-static').each(function() {
_values.push($(this).val());
//console.log($(this).val());
});
sameValue = false;
for ($i = 0; $i < (_values).length; $i++) {
for ($w = 0; $w < (_values).length; $w++) {
if (_values[$i] === _values[$w] && $i != $w) {
sameValue = true;
}
}
}
if (sameValue) {
alert('has the same value .');
return false;
}
alert('there is no the same value');
//do something .
}
</script>
This is the insert code when I'm creating the survey
<?php
$con = mysqli_connect("localhost","root","","imetrics");
if(isset($_POST['submit'])){
$title = $_POST['surveytitle'];
$catdd = $_POST['catdd'];
$subcatdd = $_POST['subcatdd'];
$gender = $_POST['gender'];
$age = $_POST['age'];
$occupation = $_POST['occupation'];
$occupationtwo = $_POST['occupdd'];
$relstatus = $_POST['relationshipstatus'];
$q_num = $_POST['q_num'];
$insert = mysqli_query($con, "INSERT INTO `surveyform` (`surveytitle`,`surveycategory`,`surveysubcategory`,`gender`,`age`,`occupation`,`occupation_status`,`status`) VALUES ('$title','$catdd','$subcatdd','$gender','$age','$occupation','$occupationtwo','$relstatus')");
if(!$insert){
echo mysqli_errno();
}
else{
$getMaxID = mysqli_query($con, "SELECT MAX(survey_id) as maxid FROM surveyform");
$row_2 = mysqli_fetch_array($getMaxID);
$survey_id = $row_2[0];
for( $a = 1; $a <= $q_num; $a++)
{
mysqli_query($con, "INSERT INTO surveyform_questions ( survey_id, question_id) VALUES ('$survey_id', ". $_POST['question_dropdowns'.$a] .")");
//echo "INSERT INTO surveyform_questions ( survey_id, question_id) VALUES ('$survey_id', ". $_POST['question_dropdowns'.$a] .")";
}
echo '<script language="javascript">';
echo 'alert("Survey Created!")';
echo '</script>';
}
}
?>
And this is my dropdown code
if($question !="" && $cnt!="" && $addQues!="yes" && $main != 1){
$i = 0;
for ($i = 1; $i <= $cnt; $i++)
{
$query=mysqli_query($con, "SELECT * FROM question WHERE question_subcat = $question ");
echo "<b>Question #". $i."</b>";
echo "<select id='question_dropdown".$i."' class='form-control-static' name='question_dropdowns".$i."'>";
echo "<option selected>"; echo "Select"; echo "</option>";
while($row=mysqli_fetch_array($query))
{
echo "<option value='$row[question_id]'>";
echo $row["questiontitle"];
echo "</option>";
}
echo "</select>";
echo "<br />";
}
echo "<div id='insertQuesHere".$i."'></div>";
echo "<a href='#add_question' onclick='return addQues();'>Add Question</a>";
}
here's my submit button
<input type="submit" name="" id="btnSaveSurvey" class="form-control-static" onclick="checkValues();" value="check" />
What's the validation code that will prevent me from inserting if the data chosen from the dropdown is the same? For example I generated 2 dropdowns and I chose the same datas from the dropdown, what's the validation code for it?

Please call checkValues method your submit button click
<input type="submit" name="" id="btnSaveSurvey" class="form-control-static" onclick="checkValues();" value="check" />
checkValues method below :
function checkValues() {
_values = [];
$('.form-control-static').each(function() {
_values.push($(this).val());
//console.log($(this).val());
});
sameValue = false;
for ($i = 0; $i < (_values).length; $i++) {
for ($w = 0; $w < (_values).length; $w++) {
if (_values[$i] === _values[$w] && $i != $w) {
sameValue = true;
}
}
}
if (sameValue) {
alert('has the same value .');
return false;
}
alert('there is no the same value');
//do something .
}
Also , you can see an example Example

Last, I was ask you guys about why znum.innerHTML cannot change the value.
Now, I put the javascript code inside the php language, the result still wrong...
My expected result:
Now I see the result:
After click the Check button to see newznum is correct but znum.innerHTML could not change this value
When pass the form to insert6.php, the total should be change the value.
Now, I cannot do it.
Anyone see the problem here?
Please you help me, I dun know where i get a mistake.
Thank you for reading my question!
I hope i will received the answer to help me to solve the problem

At first, Separation of logic is very important and what i see frmo your code is you are making DB calls from your view itself. Which shows poor way of coding. It will make it difficult to manager your code.
sel.options[0]= new Option("<?php
mysql_connect("localhost", "root", "root") or
die("Could not connect: " . mysql_error());
mysql_select_db("partition");
$query = "SELECT tile FROM material ORDER BY `material`.`Material_ID` ASC ;";
$result = mysql_query($query);
$row = mysql_fetch_row($result);
mysql_data_seek($result,0);
while ($row=mysql_fetch_row($result))
{
for ($i=0;$i<mysql_num_fields($result);$i++)
{
if ($row[$i]=="FF")
echo($row[$i]);
}
}
mysql_free_result($result);
?>");
Now answer to your question:
echo "newzum =0;";
echo "for(var j=0;j <=document.getElementsByName('del').length+1;j++) {" ;
echo "for (var i=0;i<=document.getElementById('total['+i+']').innerHTML.length;i++){";
echo "newzum += parseFloat(document.getElementById('total['+i+']').innerHTML);";
echo "}";
echo "}";
echo "document.getElementById('znum').innerHTML = newzum;";
echo "</script>";
This lines of code will be executed before the page is loaded as its php.
as a result, when the page is rendered the script will not find document.getElementsByName('del') so it will throw undefined error.
To overcome this, Do those actions in onload function.
window.onload = function() {
// Inside this method put those lines. It will work.
}

Your code is too long, but I will try to answer from your title.
You must understand how php and javascript work. php is a server-side language, while javascript is a client side language. You can NOT execute php inside javascript. php does the processing on the server and then returns the results to the client. After this, the server is not aware of the client state.
In order to change the value of innerHTML, you can just use javascript. If you need to somehow interact with php, you should send AJAX calls to the server, where the php script can process and return new data.

The PHP will just echo the Javascript code, which is fine, but needlessly complex. You can just enter the Javascript code in the page.
The actual problem right now is this line:
document.getElementById('znum').innerHTML = newzum;
It is a line of Javascript in the global scope, and it will be executed as soon as the browser encounters it during the loading of the page.
But the element is should modify ('znum') is a couple of lines lower on the page:
<b id="znum">0</b>
That basically means that the element is not ready yet when the script is executed, so it cannot be found.
The solution is relatively simple: Execute the Javascript later (at the bottom) of the page, so it will execute when all relevant elements are already loaded.
Script errors like this result in an error or a warning which should be visible in the Console tab in the developer tools (F12) of your browser. So make sure you always look at that when debugging Javascript. It's really a tool you should master as a web developer. :)
