PHP,Javascript, select and alert

Hello I am new to Javascript and currently trying to update another developers code. I have a very simple 4 question for with a mix of checkboxes and text fields.
My first piece of Javascript works: it says if there is no info typed in postsitesurvey then alert that it must be filled out. The next step I am stuck on. The employee has 2 visible options and 1 hidden. Were parts left over? I want it that if he checks yes then the next field which is the Left with field must be filled out and if not yes then he can go ahead and submit the form. Any help would be appreciated.
echo "<form id=\"myForm\" name=\"myForm\" method=\"post\" action=\"edit.php?
action=upbill2\" onsubmit=\"return validateForm()\">";
echo "<table width=\"100%\" border=\"0\" cellspacing=\"5\" cellpadding=\"0\"

echo "<div class=\"col-sm-6\">";
echo "<b>Post Site Survey</b>";
Echo "&nbsp&nbsp&nbsp";
echo "<textarea style=\"width:70%\" name=\"postsitesurvey\"
id=\"postsitesurvey\" value=\"$postsitesurvey\" />";
echo $postsitesurvey;
echo "</textarea>";
echo "</div>";

----JAVASCRIPT----
function validateForm() {
var x = document.forms["myForm"]["postsitesurvey"].value;
if (x == "") {
alert("Post site survey must be filled out");
return false;
}

I removed the distracting stuff, you can copypaste to your question, I will then delete this post...
<?php
$checked_1 = ($eq_left == "1") ? 'checked="checked"' : '';
$checked_2 = ($eq_left == "2") ? 'checked="checked"' : '';
$checked_3 = ($eq_left == "") ? 'checked="checked"' : '';
$checked_4 = ($eq_poc == "MCS") ? 'checked="checked"' : '';
?>

<input name="eq_left" type="checkbox" id="eq_left_yes" value="1" <?=$checked_1?>/>
<input name="eq_left" type="checkbox" id="eq_left_no" value="2" <?=$checked_2?>/>
<input name="eq_left" type="checkbox" id="eq_left_empty" value="" style="display:none;" <?=$checked_3?>/>
<b>Left with?</b>
<input name="eq_poc_" type="text" id="eq_poc" value="$eq_poc" placeholder="Name of customer"/>
<b>or</b>
<input name="eq_poc" type="checkbox" id="chkNo" value="MCS" <?=$checked_4?>/><b>MCS</b>
<input name="st_id" type="hidden" id="st_id" value="3" />
<input name="job_id" type="hidden" id="job_id" value="<?=$job_id?>" />
<input type="submit" name="Submit" value="Submit" class="btn btn-primary"/>
</form>

I think something like this would work for you. I changed your checkboxes to radio buttons and removed the eq_left = "". You also had two fields with the name "eq_poc". You cannot do this. I removed one, but you may want to consider a different option or explain what you are trying to do a bit better.
I have also added a toggleHide() function to show or hide the customer name field.
Alert messages can be annoying, so I removed them and added a <div> to put error messages on the page in red color.
One other thing to note is that I added the required attribute to your textarea. This allows the browser to inform the user that they haven't filled in a required field. Doing it this way, however, will not show the error message on the page in red. So, depending how you want to implement it, you may want to remove the required attribute.
The following code below will work by itself, once you are happy with it, remove the two lines at the top that are for testing and see if it works with variables passed from your other code.
<?php
//The two lines below are for testing purposes only. Once you are done testing, you can remove them to implement it with the rest of your code.
$eq_left = "1";
$eq_poc = "";
$checked_yes = ($eq_left == "1") ? 'checked="checked"' : '';
$checked_no = ($eq_left == "2") ? 'checked="checked"' : '';
?>
<html>
<script>
function toggleHide() {
var equipment_left = document.getElementById('eq_left_yes').checked;
if (equipment_left){
document.getElementById('leftwith').style.display = 'block';
}
else {
document.getElementById('leftwith').style.display = 'none';
}
}
function validateForm() {
var message = "";
var postsitesurvey = document.getElementById('postsitesurvey').value;
if (postsitesurvey == "") {
message = "Post site survey must be filled out";
}
else if (equipment_left && eq_poc == ""){

If you should send an email after form submitting, you can use the php "mail()" function (http://php.net/manual/en/function.mail.php).
Or, if you wanna use SMTP protocol you should integrate in your project a plugins like PHPMailer. See ya!

PHP - MySQL - Sign Up Trouble [blank data]

I've a website since 2013. I've signed up quite 12k users. From 5 months I have noticed some blank users. They receive a user-code but "name" "surname" and "email" fields are blanks.
This event happen every 50/100 users registrations. Why? I have tried everything, but in all test I can't sign up without data. Also other people that have made tests can't sign up without insert data.
This is the form:
<form action="script/****.php" method="post" onsubmit="return validate()">
<label for="name">Name</label>
<input type="text" id="name" name="name" <?php if($_REQUEST['name'] != "") echo "value='".$_REQUEST['name']."'"; ?> />
<label for="surname">Surname</label>
<input type="text" id="surname" name="surname" <?php if($_REQUEST['surname'] != "") echo "value='".$_REQUEST['surname']."'"; ?> />
<label for="email">Email</label>
<input type="email" id="email" name="email" <?php if($_REQUEST['email'] != "") echo "value='".$_REQUEST['email']."'"; ?> />
<label for="c_email">Retype Email</label>
<input type="email" id="c_email" name="c_email" />
<label for="password">Password</label>
<input type="password" id="password" name="password" />
<label for="c_password">Retype Password</label>
<input type="password" id="c_password" name="c_password" />
<input type="submit" value="registrati" />
</form>
This is the code that stores data on db:
<?php
function mt_rand_str ($length, $available = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789abcdefghijklmnopqrstuvwxyz0123456789') {
for ($string = '', $i = 0; $i < $length; ++$i) {
$string .= $available[mt_rand(0, strlen($available)-1)];
}
return $string;
}
include('connection.php');
$con = connection();
$name = $_POST['name'];
$surname = $_POST['surname'];
$email = $_POST['email'];
$password = $_POST['password'];
$bonus = 10;
$today = new DateTime();
$signUpDate = $today->format('Y-m-d');
if(strpos($name,' ') !== false) {
echo "
<script>
alert('Nome non valido!');
window.location.href = '../signup.php';
</script>";
exit;
}
if(strpos($surname,' ') !== false) {
echo "
<script>
alert('Cognome non valido!');
window.location.href = '../signup.php';
</script>";
exit;
}
if(strpos($email,' ') !== false) {
echo "
<script>
alert('Email non valida!');
window.location.href = '../signup.php';
</script>";
exit;
}
if(strpos($password,' ') !== false) {
echo "
<script>
alert('Password non valida!');
window.location.href = '../signup.php';
</script>";
exit;
}
connectionCheck($con);
userDbCheck($con);
$checkEmail = mysqli_query($con,"Select * from Users_DB where email = '$email'");
if(!mysqli_fetch_assoc($checkEmail)) {
do {
$userCode = mt_rand_str(8);
}
while(mysqli_fetch_assoc(mysqli_query($con,"select * from Users_DB where binary UserCode = '$userCode'")));
$value = 20;
mysqli_query($con,"Insert into User_DB (UserCode,Name,Surname,Phone,Email,Password,SignUpDate,bonus)
values ('$userCode','$name','$surname','','$email','$password','$signUpDate','$bonus')");
}
else {
echo "
<script>
alert('Email exists already!');
window.location.href = '../signup.php';
</script>";
}
?>
I hope you can find what I have not. As you can see, I've put in php code some data check too.
So I have
1) HTML5 check: type="email". I'm thinking to put also "pattern match" in all fields
2) JavaScript check
3) PHP check
I'm so desperate...
Thank you before.

Ajax jQuery retrieving data from previous query

I'm currently using Ajax & jQuery for my chat, some might say its stupidly complex but so long as I can get it working.
It works on the first friend result, how ever not on the other. What its doing is the chat-load.php (Ajax part) is creating a new query to select the friends details, which are then being put into a result query on the chat.php page.
Therefore it only displays one "Working" chat window for the 1st friend. I tried grabbing the previous friend_id from the chat.php query and using it in the chat-load.php query but it didn't seem to notice any data.
Here is an example of what I'm getting, 1st result full width meaning its working, other results not full width as not working with ajax.
This is my current setup:
chat.php
<?php $users = $db->query("SELECT DISTINCT users.id, users.firstname, users.lastname,
message.date, message.time, message.message, message.recipient, message.sender
FROM users
JOIN friends
ON users.id IN (friends.sender, friends.recipient)
JOIN message
ON (users.id = message.sender)
AND 75 IN (message.sender,message.recipient)
ORDER BY message.date DESC, message.time DESC"); ?>
<!-- Friends query -->
<?php $users = $db->query("SELECT IF(friends.sender = ".$_SESSION["user"]["id"].", friends.recipient, friends.sender) AS user_id
FROM friends
WHERE friends.sender = ".$_SESSION["user"]["id"]."
OR friends.recipient = ".$_SESSION["user"]["id"].""); ?>
<?php while($friend = $users->fetch_object()): ?>
<?php $friends = $db->query("SELECT firstname, lastname, id FROM users WHERE id = $friend->user_id "); ?>
<?php while($FriendName = $friends->fetch_object()): ?>
<div class="chat-box">
<div class="header">

Try using $.ajax() instead of $.load(). Set cache: false.
Example:
function loadlink(){
$.ajax({
url:'chat-load.php',
cache: false,
success: function(result){
$('#messages').html(result);
}
});
}
