How to change database Boolean using php - javascript

Basically I want to send the same message to several recipients and I want it to register with a checkbox if the email was sent to that user or unchecked if it wasn't(The user has to check the checkbox so it registers) and I can't find a way so when a user checks a checkbox it gets updated in the database. I've tried with Ajax but I've no idea how to properly use it. I need some serious help.

Show/hide info using slideToggle on button

Objective Inserting name(input-text) and info(textarea-contains multiple lines) into the database, and after submission of the form, at the same page, 2 columns are for displaying the same data in columns, name & info, but under info column. I have made buttons for each row in front of the names, which is used as slideToggle for showing/hiding which contains the data retrieved from the 'info' column
Problem - when I am clicking the button of 1st row, instead of displaying the info related to 1st entry only, it is sliding and showing all info(s) related to all entries at only click.
*others - one more input has been added to the form but as hidden used for id(auto increment)

$n = mysqli_fetch_array($record);
$name = $n['name'];

Concept:
If you are creating multiple form from same mysql table using php script, You need to give each form a unique id.
e.g.
<form method="post" action="php_code.php" id="form<?= $id ?>">
Then add data-target="#form" to button with class 'inf'. It will store id of form.
<button class="inf" data-target="#form<?= $id ?>">show</button>
When button is clicked we know which form to open from data-target.
<script>
$('.container').on('click','button.inf',function(e){
e.preventDefault();
var formid=$(this).attr('data-target'); //get value of data-target attribute
//...proceed to play toggle with this form 'formid'

How to get via onclick and POST data on redirect with POST

I'm working using ajax,javascript, php and still new with this.
Here the scenario, I have a button with onclick function in my index.html page when I click that button I want it to redirect me to another my getdata.php page while posting and id. So when I've been redirected to my getdata.php page I just need to query using that id.
The button that trigger redirection are located at index.html <button class="btn btn-default print" name="print" data-username="{{"'.$row['msid'].'"}}" onclick="generatepdf()"><span class="icon-printer"></button>
The following codes I've been using right now. I hope I've got a lot of help right here.

Easy way is not using JS or Jquery for your requirement. Just use HTML form and PHP only like following in your index.php.
<?php
//In you index.php
//.....................
//..........................
//your other codes
//......................
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
?>
<form method="post" action="getdata.php">
<input type="hidden" name="my_id" value="<?php echo $row['msid']; ?>" />
<input type="submit" value="REDIRECT AND POST MY ID" />
</form>
<?php
}
} else {
echo "0 results";
}

You just need to replace the button code with this form code and your ID will be posted and redirected to getdata.php page because of the form attribute action="getdata.php".
See the form method is post this means your form will be submitted using POST method. Now in your getdata.php file do following
<?php
$posted_id = $_POST['my_id'];
echo $posted_id;
//now get data from DB using this id
//get data from db where id = $posted_id
This is not full code for getdata.php but you will see at least your posted id(from index.php to getdata.php) using this code. There are lots to do like checking http method, error handling etc etc.

boolean error in php code in php with mysql

im having problem with the integration of text fields with php by $_post method and i've done almost complete code but it giving me boolean error in line 84 which is
if(mysqli_num_rows ||($run)==0)
and my whole code is

$db_password = "123456789";
$db_name = "users_db";
$conn = new mysqli($servername, $db_username, $db_password, $db_name);
//fatching data from form
if(isset($_POST['submit'])){
$user_name = $_POST['name'];
$user_pass = $_POST['password'];
$user_email = $_POST['email'];
//validatio form
if($user_name==''){
echo "<script>alert('please enter usernmae')</script>";
exit();
}
if($user_pass==''){
echo "<script>alert('please enter password')</script>";
exit();
}
if($user_email==''){
echo "<script>alert('please enter email')</script>";
exit();
}
$check_email = "select * from users where user_email='$user_email'";
$run = mysql_query($check_email);
if(mysqli_num_rows ||($run)==0){
echo "<script>alert('Email $check_email is already exist')</script>";
exit();
}
//Getting values from fields of registration form
$query = "insert into users(user_name, user_pass, user_email) values($user_name, $user_pass, $user_email)";
if(mysql_query($query)){
echo "<script>alert('registration successful')</script>";
}
}
?>
The function mysqli_num_rows() need a mysqli_result parameter and if you want the logic to work correctly the test is actually wrong as well
So change
if(mysqli_num_rows ||($run)==0){
To
if(mysqli_num_rows($run) > 0) {
This query will also fail
$query = "insert into users(user_name, user_pass, user_email)
values($user_name, $user_pass, $user_email)";
All text column variables should be wrapped in quotes like this
$query = "insert into users(user_name, user_pass, user_email)
values('$user_name', '$user_pass', '$user_email')";
But I have to mention that Your script is at risk of SQL Injection Attack
Have a look at what happened to Little Bobby Tables Even
if you are escaping inputs, its not safe!
Use prepared parameterized statements

How not to redirect HTML file to php

I am very new to php just today itself I have started learning it, I am doing a simple program from of selecting a row from mysql's database based on user input on html through php file . and my concern is when I submit the form , it redirects to to the php and the output is displayed on the php, how can I display the result on the HTML page itself I mean the user shouldn't feel there is any transition from html to php any we get the output on the html page
HTML page :
<!DOCTYPE HTML>
<html>
<head>
</head>
<body>
<form action="index.php" method="get">
Enter Name : <input type="text" id="txt1" name="user">
<input type="submit" name="enter">
</form>
</body>
php page :
<?php
$dbhost = "localhost";
$username = "root";
$password = "";
mysql_connect($dbhost,$username,$password);
#mysql_select_db("trynew") or die(mysql_error());
if (isset($_GET["user"])) {
$user = $_GET['user'];
}
$query = "SELECT * FROM trynewtable where name = '$user' ";
$result = mysql_query($query);
if($result==FALSE)
{
die(mysql_error());
}
$row = mysql_fetch_array($result);
echo $row[0];
echo $row[1];
echo $row[2];
echo $row[3];
mysql_close();
?>
On the user side theres no difference between html and php, php files are also html in the view of the browser. The only difference is that php files are interpreted by the server ,while html is just send. So you can put your html in your php and mix it all together:
index.php:
<body>
<div id="response">
<?php
if($_SERVER["REQUEST_METHOD"]=="POST"){
//do your request
}else{
echo "please fill in the form";
}
?>
</div>
//your form etc
Simple answer You can merge the HTML and PHP files unless there is a need to separate them (if so use AJAX). Do a validation before any database interaction. Do not use mysql but mysqli_
<?php
$dbhost = "localhost";
$username = "root";
$password = "";
$col1 = $col2=$col3=$col4="";
mysql_connect($dbhost,$username,$password);
#mysql_select_db("trynew") or die(mysql_error());
if (isset($_GET["user"])) {
$user = $_GET['user'];
$query = "SELECT * FROM trynewtable where name = '".mysql_real_escape_string($user)."' ";
$result = mysql_query($query);
if($result==FALSE) {
die(mysql_error());
}
$row = mysql_fetch_array($result);
$col1 = $row[0];
$col2 = $row[1];
$col3 = $row[2];
$col4 = $row[3];
}
mysql_close();
?>
<!DOCTYPE HTML>
<html>
<head>
</head>
<body>
<?php echo $col1." ".$col2." ".$col3." ".$col4;?>
<form action="" method="get">
Enter Name : <input type="text" id="txt1" name="user">
<input type="submit" name="enter">
</form>
</body>
