} catch (PDOException $exc) {
echo $exc->getMessage();
exit();
}
// id to search
$email = $_POST['email'];
// mysql search query
$pdoQuery = "SELECT * FROM member WHERE email = :email";
$pdoResult = $pdoConnect->prepare($pdoQuery);

I have work out what you need, it require email (like foobar#gmail.com) and date (like 2018-09-23) in the form input field, if you submit it return the Reservation Name.
Notice for simplicity reason I removed these 3 columns "persons", "time" and "status", but you can add it back, it doesn't change the logic because the finding/query don't need those fields for input
This is my code:
<?php
// php search data in mysql database using PDO`enter code here`
// set data in input text
function sqlInitConn ($args) {
// Initialze connection.
$serverName = $args["serverName"];
$userName = $args["userName"];
$password = $args["password"];
$dbName = $args["dbName"];
$conn = new PDO("mysql:host=$serverName;dbname=$dbName", $userName, $password, array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8"));
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
return $conn;
}
// Those variables are for input to mysql.
$idIpt = "";
$reservation_nameIpt = "";
$emailIpt = "";
$dateIpt = "";
// Those variables are for output to front-end.
$idOpt = "";
$reservation_nameOpt = "";
$emailOpt = "";
$dateOpt = "";
if(isset($_POST['find']))
{
try {
// Connect to mysql.
$pdoConnect = sqlInitConn([
"serverName" => "localhost",
// Change it to your server name.
"userName" => "root",
"password" => "change_it_to__your_password_here_if_your_mysql_need_password",
"dbName" => "multi_edit",
]);
} catch (PDOException $exc) {
echo $exc->getMessage();
exit();
}
$emailIpt = $_POST['email'];
$dateIpt = $_POST['date'];
$pdoQuery = "SELECT * FROM member WHERE email = :email AND date = :date";
// Mysql search query
$pdoResult = $pdoConnect->prepare($pdoQuery);
$pdoResult->bindValue(":email", $emailIpt);
$pdoResult->bindValue(":date", $dateIpt);
$pdoExec = $pdoResult->execute();
if($pdoExec) {
// If record exist, show data in inputs
if($pdoResult->rowCount() > 0) {
foreach($pdoResult as $row) {
$idOpt = $row['id'];
$reservation_nameOpt = $row['reservation_name'];
$emailOpt = $row['email'];
$dateOpt = $row['date'];
break;
// only get first occurrences (get first matching record) to prevent corrupted data
// , because same email might wrongly log twice in same day (= same date), like morning and afternoon.).
}
}
else {
echo 'No Reservation Found On This Email';
// If the id not exist, show a message and clear inputs
}
} else {
echo 'ERROR Something Is Wrong Try Again';
// If the id not exist, show a message and clear inputs
}

how to fix error of empty $_POST['name']

I want to have a form with php. but for many hours I'm involved an error and the error is when $_POST=['name'] wants to be checked empty or not it is empty.
When I check the database the row is white and nothing is there.
for checking if the $_POST is empty or not I print word 'empty' to be determined it's empty and it will be printed 'empty';
where is my mistake is it related to database mysql or not just in code?
please help me I got confused and bored.
this is whole of my codes:

$name = test_input($_POST["name"]);
// check if name only contains letters and whitespace

</form>
</body>
</html>
thank you in advance
The problem is in use of empty()
You can use it on variables not on values.
See here for PHP documentation page.
To check this, first save it in another variable and then check:
$tempVal = $_POST["name"];
if (empty($tempVal))
you can use this simple example
<?php
if(isset($_POST['submit']))
{
$name = $_POST['name'];
echo "User Has submitted the form and entered this name : <b> $name </b>";
echo "<br>You can use the following form again to enter a new name.";
}
?>
<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<input type="text" name="name"><br>
<input type="submit" name="submit" value="Submit Form"><br>
</form>
i suggest this:

Updating one particular data updates the entire record in MYSQL using PHP

I wanna update just one data from a record using php form but the thing is, when i do that, the rest of the data gets removed from the record.. What do i do :/ here are my codes for updating. What is the mistake i am making.. I am very confused. Would really appreciate some help.
<?php
include('db.php');
if(isset($_POST['update']))
{
$hostname = "localhost";
$username = "root";
$password = "";

$age = $_POST['age'];
$country=$_POST['country'];
$phone=$_POST['phone'];
$email=$_POST['email'];
$select = "SELECT * FROM studens WHERE id = '$id'";
$selected = mysqli_query($connect, $select);
$row = mysqli_fetch_assoc($selected);
if (empty($_POST['fname'])) {$fname = $row['fname'];} else {$fname = $_POST['fname'];}
if (empty($_POST['country']))
{
$country = $row['country'];
}
else {
$country = $_POST['country'];
}
if (empty($_POST['id'])) {
$id = $row['id'];
}
else {
$id = $_POST['id'];
}
if (empty($_POST['age'])) {$age = $row['age'];} else {$age = $_POST['age'];}
if (empty($_POST['phone'])) {$phone = $row['phone'];} else {$phone = $_POST['phone'];}
if (empty($_POST['email'])) {$email = $row['email'];} else {$email = $_POST['email'];}
$query = "UPDATE students SET Fname= '$fname', Lname = '$lname', Nationality = '$country', PhoneNumber = '$phone', Email= '$email', Age = '$age' WHERE Id = '$id'";
$result = mysqli_query($connect, $query);
var_dump($result);
if($result)
{
echo 'Data Updated';
}else
{
echo 'Data Not Updated';
}
mysqli_close($connect);
}

The select statement is fetching data from a table called studens. This looks like a typo of the actual table so it won't actually fetch any results for you to update. Thus, the data you wind up updating the table with is empty. Rename the initial select table to students and it should properly fetch the data.
Also, please look into prepared statements or various other methods to sanitize inputs. Using POST variables directly in a query makes you extremely vulnerable to SQL Injection.

Insert data mysqli and php in form 1 and return to new form 2

Hi all I am new to mysqli and php (currently studying and trying to work on a test database- I have not used security measures at this wont be available public) and trying to get the information I have just submitted in the form to display in a new form which will then receive further user input then submitted to database. Here is an example of what I have done so far:
Form 1 (customer table - cust id =primary key)
Customer Details ie name address telephone etc
dynamic drop down box - consists of 4 options.( would like whatever option is selected here to return a particular form)
The form is currently submitting correctly in the database, but I would like once it has submitted to the database to return the customer info (including the customer id as that is the relationship in the new table) and on the form2(service table - service id is primary key) so the user can input further data to the form and submit.
Hope this makes sense, any help would be appreciated.
Thanks
Response 1
Thank you for my response I probably havent made myself very clear.
Form 1 where dynamic dropdown list is - when user submits forms I would like it to return form 2 with the customer info we inserted in form 1

Assuming you are using a database object like mysqli to do DB interactions.
Say form1 generate insert query $insertQyery.
And you are executing this query (insert statement) like
$mysqli->query($insertQyery);
After the execution of this insert statement you can use
$customerId = $mysqli->insert_id
Now using this $customerId you can show records details on form2 or use this $customerId as reference on form2.
After customer submit FORM #1
on the next page
let's get the last customer details :-
<?php
//after mysqli connection
$contactFirstName = '';
$contactLastName = '';
$businessName = '';
$sql_get_data = "SELECT * FROM customer ORDER BY customerID DESC limit 1 ";
$query_get_data = mysqli_query($conn, $sql_get_data);
while ($row = mysqli_fetch_array($query_get_data, MYSQLI_ASSOC)) {
//specify which data you want to get from "customer" table
$contactFirstName = $row['contactFirstName'];
$contactLastName = $row['contactLastName'];
$businessName = $row['businessName'];
}
?>
HTML Form#2 :-
<form id="form2" method="post">
<input type="text" value="<?php echo 'contactFirstName'; ?>"
<input type="text" value="<?php echo 'contactLastName'; ?>"
<input type="text" value="<?php echo 'businessName'; ?>"
</form>
Hope this answer will help you.

What version of PHP you are using to run this script?
As I can see you are using "Register globals" setting to get $_POST data: http://php.net/manual/en/security.globals.php
If you have PHP version 5.4+ you should use $_POST['form_field_name1'] ... $_POST['form_field_nameN'] to get form data.
Add check:
if (!empty($_POST)) { /* Form validation data goes here */ }
File is incorrect, the form action url points to default.php but your filename is defaul.php
Make if default.php instead of defaul.php
For better handling:
In console of your browser, please check the http call, you can see the error it is showing if its a 500 (check logs / enable the debug mode)

I am attempting to make a login using phpmyadmin, but, when I click submit, it inserts blank entries into the database

My class is attempting to make our own game.. But, we can't get the submit page to send to the database in PhpMyAdmin. When you click submit, it sends blank entries to the database, like if you hadn't filled in any of the blanks. Can someone help with this problem. Thanks!!

UPDATE:
I added in the changes that someone had suggested in moving the checks to insert.php and now the email and confirm email check does not work. Can anyone help?

I see two main problems here -
First, the action of your form points to itself. That means that the $_POST array submits to index.php, and your insert.php page has no access to that information. Index.php runs through the validation checks, and if everything checks out, it assigns the $_POST values to variables and quits. That's where the data dies. There is no method for getting the information over to the file insert.php. So if you manually open the file insert.php in a browser, the $_POST array will be empty, and it will simply insert blanks.
There are several ways to resolve this. The simplest, most expeditious way would be the single page solution - move the insert.php code into the index.php file inside that last else block.
else {
//echo "next date <br>";
// create account
$Username = $_POST['name'];
//etc.. code to insert data from insert.php
Another solution would be to move all the validation code to insert.php, display any form errors on that page, and make the user go back a page if validation fails. In that case, you would change the action of the form to insert.php:
<form action="insert.php" method="post">
This approach is less user-friendly, and not an ideal solution. Really a better practice is to use Javascript for form validation and PHP for form processing. That may be outside the scope of your class...
Second, this code is wide open to SQL injection. Instead of putting variables directly into your SQL statements, you need to use parameterized queries. Take a look at this SO question about how to parameterize queries with mysqli.
The mistakes that I found:
First things first your code submits the values received from the form to index.php itself so there is no question of values getting insert at the first place because the insert query is not run.
In index.php check the query to SELECT email and username. The variables do not have any value when the query is run because the values get transferred couple of lines AFTER the queries (at the lines where you have $email = $_POST['Email']). Moreover you have missed the $ sign in the query related to email.
Coming to insert.php you have missed quotes in the global variable $_POST[] in the insert query viz. $_POST['email'].
Check for these errors and let me know if it works.
