I am trying to save the information stored in the SQL but this error keeps coming out: "Error Saving Data. You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'company = 'GlobalTop Inc.' where regid = 1' at line 6" What seems to be the error?
Here is the full code:

You have missed , in both if and else statement after email = '$email'
if ($_POST['action_type'] == 'add')
{
$sql = "insert into tblregistrants set
name = '$regname',
phone = '$phone',
address = '$address',
email = '$email',
company = '$company'";
}else{
$sql = "update tblregistrants set
name = '$regname',
phone = '$phone',
address = '$address',
email = '$email',
company = '$company'
where regid = $regid";
}
Also use Prepared statement to prevent from SQL injection
as Lawrence suggested you are missing , on your query
try this:
$sql = "insert into tblregistrants set
name = '$regname',
phone = '$phone',
address = '$address',
email = '$email',
company = '$company'";
Change this,
$sql = "update tblregistrants set
name = '$regname',
phone = '$phone',
address = '$address',
email = '$email',
company = '$company'
where regid = $regid";
To this
$sql = "update tblregistrants set
name = '$regname',
phone = '$phone',
address = '$address',
email = '$email',
company = '$company'
where regid = '$regid'";

So when I want to retrieve data and check it i.e. if the email already exist echo already registered. That part works fine, however inserting the same data does not work. Are my conditionals ordered improperly?
(intentionally left out values for the dbhostname id pw variables)
$dbname = "hw2";
$link = mysqli_connect($dbhostname, $dbuserid, $dbpassword, $dbname);
$firstname = $_POST["signup-firstname"];
$lastname = $_POST["signup-lastname"];
$email = $_POST["signup-email"];
$password = $_POST["signup-password"];
$repassword = $_POST["signup-repassword"];
if ($password != $repassword){
echo "<br><h3>Passwords did not match. <br>Please try again.</h3>";
}
else {
$ret_email = "SELECT * FROM hw2 WHERE email = '$email'";
$result = mysqli_query($link, $ret_email);
$num_rows = mysqli_num_rows($result);
if ($num_rows > 0){
echo "This email is already registered.";
}
else{
$insert_query = "INSERT INTO hw2 (firstname, lastname, email, password, repassword) VALUES ('$firstname', '$lastname', '$email', '$password', '$repassword')";
echo "$insert_query";
}
}
?>
You should perform the query not only echoing it
mysqli_query($con,"INSERT INTO Persons (FirstName,LastName,Age)
if ($num_rows > 0){
echo "This email is already registered.";
}
else{
$insert_query = "INSERT INTO hw2 (firstname, lastname, email, password, repassword) VALUES ('$firstname', '$lastname', '$email', '$password', '$repassword')";
echo "$insert_query";
mysqli_query($link,$insert_query)
}
i'm new to this PHP please help me here i'm unable to insert values into table.
But if i gave values directly to insert command in place of variables it works.
<?php
include ("db.php");
$msg = "";
if(isset($_POST["submit"]))
{
$name = $_POST["name"];
$email = $_POST["email"];
$password = $_POST["password"];
$name = mysqli_real_escape_string($db, $name);
$email = mysqli_real_escape_string($db, $email);
$password = mysqli_real_escape_string($db, $password);
$password = md5($password);
$sql="SELECT email FROM users2 WHERE email='$email'";
$result=mysqli_query($db,$sql);
$row=mysqli_fetch_array($result,MYSQLI_ASSOC);
if(mysqli_num_rows($result) == 1)
{
$msg = "Sorry...This email already exist...";
}
else
{
$query = mysqli_query($db, "INSERT INTO users2 (name, email, password)VALUES ('$name', '$email', '$password')");
if($query)
{
$msg = "Thank You! you are now registered.";
}
}
}
?>
$sql = "INSERT INTO users2 (name, email, password) VALUES (?,?,?)";
if (!$stmt = $db->prepare($sql)) {
die($db->error);
}
$stmt->bind_param("sss", $name, $email, $password);
if (!$stmt->execute()) {
die($stmt->error);
}
I don't know what is the problem in my above question but
i used the above query instead of the one i used the in question and Boom it is a success.
if any one of you know whats the problem in the question please let me know.
You have to concat the variable in string of insert not just put as variable
$query = mysqli_query($db,"INSERT INTO users2 (name, email, password)VALUES ('".$name."', '".$email."', '".$password."')")
or
$query = mysqli_query($db,"INSERT INTO users2 (name, email, password)VALUES ('{$name}', '{$email}', '{$password}')")
You should use prepare statement for this mysql_real_escape_string-versus-Prepared-Statements
Never use md5() is-md5-considered-insecure
Prefer password_hash() or password_verify() Manuel
``
here my php program for same:
public function updateUser($id,$name,$lname,$username,$password,$gender,$email,$mobile,$address) {
printF($id);
$update = ("UPDATE oops SET firstname = '$name',lastname = '$lname', username= '$username',password='$password',email = '$email', gender = '$gender', mobile = '$mobile' , address = '$address' WHERE uid = '$id'");
printF($update);
$result = mysql_query($update);
if ($result) {
return true;
} else {
return false;
}
}
Try removing () parenthesis from $update variable and DO NOT use mysql_* features , use mysqli_* instead of mysql_*
public function updateUser($id,$name,$lname,$username,$password,$gender,$email,$mobile,$address) {
printF($id);
$update = "UPDATE oops SET firstname = '$name',lastname = '$lname', username= '$username',password='$password',email = '$email', gender = '$gender', mobile = '$mobile' , address = '$address' WHERE uid = '$id'";
printF($update);
$result = mysqli_query($update);
if ($result) {
return true;
} else {
return false;
}
}
I cannot update my existing data in the tabular form of my CRUD web application. Is there anything wrong with the query ? This is my source of reference and I have follow the UPDATE query exactly as in here INSERT, UPDATE and DELETE with mysqli. This is my code.
<?php
//error_reporting(E_ALL^E_NOTICE);
function chgDate($date){
$temp=explode("-",$date);
return $temp[2]."-".$temp[1]."-".$temp[0];
}
$json=array();
$ic = $_POST['IC'];
$Fic = $_POST['fromIC'];
$name = $_POST['formName'];
$tel = $_POST['formTelephone'];
$gender = $_POST['formGender'];
$email = $_POST['formEmail'];
if(isset($_POST['formUni'])){
$uni = $_POST['formUni'];
}
$age = $_POST['formAge'];
$address = $_POST['formAddress'];
$dob = $_POST['formDOB'];
$process= $_POST['process'];
//include ("connect_db.php");
//include_once('connect_db.php');
$db = mysqli_connect("localhost","root","admin","li") or die("Connection Error: " . mysqli_error());
if($process == 'save'){
$SQL="Insert into biodata (IC, Name, Telephone, Gender, Email, University, Age, Address, DOB) values ('$Fic', '$name', '$tel', '$gender', '$email', '$uni', '$age', '$address', '".chgDate ($dob)."')";
$json['newrow']=$Fic;
} else if ($process == 'edit') {
$SQL="UPDATE biodata SET IC='$Fic', Name='$name', Telephone='$tel', Gender='$gender', Email='$email', University='$uni', Age='$age', Address='$address, DOB ='".chgDate ($dob)."' WHERE IC= '$ic'";
} else if ($process == 'delete') {
$SQL = "DELETE FROM biodata WHERE IC='$ic'";
}
$data = mysqli_query($db, $SQL);
if($data){
$json['msg']='success';
}else{
$json['msg']='fail';
}
echo json_encode($json);
?>
It seems you forgot to end the quotes
Address='$address'
Check it
$SQL="UPDATE biodata SET IC='$Fic', Name='$name',
Telephone='$tel', Gender='$gender', Email='$email', University='$uni',
Age='$age', Address='$address', DOB ='".chgDate ($dob)."' WHERE IC= '$ic'";
My code should be checking the database to see if the custID exists, and if it does, to update the information. It it doesn't, it needs to add the customer information to the database.
Currently, when I use the code I have, each time an order is made on the website, a new custID is added to the database.
These errors are occurring:
When a new customer orders, a new row is inserted. None of the information
from the fields is put into the database, just an empty row.
When a returning customer orders, their information is drawn from the
database on a previous page, but on this page it inserts a new row and the new fields
are left blank.
If this isn't enough information or isn't clear, I will gladly offer more code and explanation.
//The information is passed through a session object from a previous page.
if (ISSET($_SESSION['fname'])) {
session_start();
$email = $_SESSION['email'];
$fname = $_SESSION['fname'];
$lname = $_SESSION['lname'];
$street = $_SESSION['street'];
$city = $_SESSION['city'];
$state = $_SESSION['state'];
$zip = $_SESSION['zip'];
$safeID = $_SESSION['safeID'];
$custID = $safeID / 507921;
}
include_once("Connection.php");
include_once("header.html");
//check if customer is already in database
$sql = "SELECT *
FROM bookcustomers
where custID = '$custID'";
$result = mysqli_query($link, $sql)
or die('SQL syntax error: ' . mysqli_error($link));
if (mysqli_num_rows($result) > 0 ) {
$sql = "UPDATE bookcustomers
set fname = '$fname',
lname = '$lname',
email = '$email',
street = '$street',
city = '$city',
state = '$state',
zip = '$zip'
WHERE custID = '$custID'";
$result = mysqli_query($link, $sql)
or die('SQL syntax error: ' . mysqli_error($link));
}
else {
$sql = "INSERT into bookcustomers (fname,
lname,
email,
street,
city,
state,
zip)
VALUES ('$fname',
'$lname',
'$email',
'$street',
'$city',
'$state',
'$zip')";
$result = mysqli_query($link, $sql)
or die('SQL syntax error: ' . mysqli_error($link));
$custID = mysqli_insert_id($link);
}
session_start should be called before your if clause.
session_start() creates a session or resumes the current one based on a session identifier passed via a GET or POST request, or passed via a cookie.
If you change the top if on your php file
session_start();
if (ISSET($_SESSION['fname'])) {
$email = $_SESSION['email'];
$fname = $_SESSION['fname'];
$lname = $_SESSION['lname'];
$street = $_SESSION['street'];
$city = $_SESSION['city'];
$state = $_SESSION['state'];
$zip = $_SESSION['zip'];
$safeID = $_SESSION['safeID'];
$custID = $safeID / 507921;
}
include_once("Connection.php");
include_once("header.html");
This will resume your session, as long as you created the session correctly and set the fname session variable on the previous page.
If you've set the values correctly and change the if clause to the one above, it should work.
Can you try this, moved session_start(); top of if (ISSET($_SESSION['fname'])) { .
<?php
session_start();
if (ISSET($_SESSION['fname'])) {
$email = $_SESSION['email'];
$fname = $_SESSION['fname'];
$lname = $_SESSION['lname'];
$street = $_SESSION['street'];
$city = $_SESSION['city'];
$state = $_SESSION['state'];
$zip = $_SESSION['zip'];
$safeID = $_SESSION['safeID'];
$custID = $safeID / 507921;
}
include_once("Connection.php");
include_once("header.html");
//check if customer is already in database
$sql = "SELECT *
FROM bookcustomers
where custID = '$custID'";
$result = mysqli_query($link, $sql)
or die('SQL syntax error: ' . mysqli_error($link));
if (mysqli_num_rows($result) > 0 ) {
$sql = "UPDATE bookcustomers
set fname = '$fname',
lname = '$lname',
email = '$email',
street = '$street',
city = '$city',
state = '$state',
zip = '$zip'
WHERE custID = '$custID'";
$result = mysqli_query($link, $sql)
or die('SQL syntax error: ' . mysqli_error($link));
}
else {
$sql = "INSERT into bookcustomers (fname,
lname,
email,
street,
city,
state,
zip)
VALUES ('$fname',
'$lname',
'$email',
'$street',
'$city',
'$state',
'$zip')";
$result = mysqli_query($link, $sql)
or die('SQL syntax error: ' . mysqli_error($link));
$custID = mysqli_insert_id($link);
}
?>
