I need to update my data in database. I am successfully created the user registration and login form in php, so i need to update and delete data in database. And I am getting error message update function.
There is condition: id(primary) and email(unique) & username(unique).
Error message in this program:

You have not added value to id.
It is a hidden variable, so, it can only be set through PHP or JS not with user input.
Therefore, your query after where clause is blank and causing error.
Solution:
Assign id a value.
<input type="hidden" name="id" placeholder="ID" value="<?php echo $user_id;?>">
And to avoid this error, check if id is posted.
Modify:
if(isset($_POST['submit'])) {
To:
if(isset($_POST['submit']) && ! empty($_POST['id'])){
I am working on a angular5 / php backend project, and I am having an issue where I have a registration form, when the user registers it creates a blank row (empty strings values) in the user table followed by the correct row (colomn values).
The following is my form:
<form *ngIf="!isLogin" (submit)="onRegisterSubmit()" [formGroup]="registerForm">
<div class="form-control">
<input type="text" name="firstname" id="firstname" class="form-control" placeholder="Firstname" formControlName="fn">
<div class="throw_error" *ngIf="registerForm.controls.fn.invalid && registerForm.controls.fn.touched">
<div *ngIf="registerForm.controls.fn.errors?.required">This field is required</div>
<div *ngIf="registerForm.controls.fn.errors?.minlength">This field must be at least 3 characters</div>
<div *ngIf="registerForm.controls.fn.errors?.maxlength">This field must have at most 10 characters</div>
</div>
</div>
<div class="form-control">
<input type="text" name="lastname" id="lastname" class="form-control" placeholder="Lastname" formControlName="ln">
<div class="throw_error" *ngIf="registerForm.controls.ln.invalid && registerForm.controls.ln.touched">
<div *ngIf="registerForm.controls.ln.errors?.required">This field is required</div>
<div *ngIf="registerForm.controls.ln.errors?.minlength">This field must be at least 3 characters</div>
<div *ngIf="registerForm.controls.ln.errors?.maxlength">This field must have at most 10 characters</div>

<span class="throw_error" id="success">{{resultReg}}</span>
</div>
<div class="col-sm-3"></div>
</div>
</div>
</form>
This is my typescript code for the registration function:
onRegisterSubmit() {
const regFormValue = this.registerForm.value;
this.http.post("http://localhost/ProjetErgonomie/RegUser.php", regFormValue)
.subscribe(data => {
this.receivedData = data;
if (this.receivedData.success) {
this.resultReg = "User added successfully";
} else {
this.resultReg = this.receivedData.errors;
}
}, (error) => {
console.log(error);
});
}
And this is my RegUser.php page:
<?php
header("Access-Control-Allow-Headers: Content-Type");
header("Access-Control-Allow-Origin: *");
require_once ('./DBConnect.php');
$conn = mysqli_connect($servername, $username, $password, $db ,$port);
$regUserData = json_decode(file_get_contents("php://input"),true);
$fn = $regUserData['fn'];
$ln = $regUserData['ln'];
$email = $regUserData['email2'];
$pass = $regUserData['password2'];
$confPass = $regUserData['confPass'];
$errorsReg = "";
$dataReg=array();
if($fn === '' || $ln === '' || $email === '' || $pass === '' || $confPass === ''){
$errorsReg = 'Please fill all fields';
$dataReg['success'] = FALSE;
}
else{
$checkUserQuery = "select * from user where Email = '".$email."'";
$result = $conn->query($checkUserQuery);
if(mysqli_num_rows($result)>0){
$errorsReg = 'User already exists';
$dataReg['success'] = FALSE;
}
else{
$sql = "INSERT INTO user (Firstname, Lastname, Email, Password, NewUser)
VALUES ('".$fn."','".$ln."','".$email."','".md5($pass)."',1)";
mysqli_query($conn,$sql);
$dataReg['success'] = TRUE;
}
}
$dataReg['errors']=$errorsReg;
echo json_encode($dataReg);
can you please tell me why am I getting a blank row before having the correct row inserted?

Guys this my code for registration. The problem here is that when a user who is not registered and adds a product into his cart goes to registration page. After signing up he needs to go the checkout page . If there are no items inside the cart then the page needs to redirected to index.php . The issue i face is the data gets entered into database when the cart has one item and then after registering it redirects to index.php rather than checkout.php .
There is small variable name mistake in
$sel_cart = "select * from cart where ip_add='$user_ip'";
You have added $user_ip instead of $userip. update your code by following,
$sel_cart = "select * from cart where ip_add='$userip'";

How to prevent duplicate usernames when people register?
(4 answers)
Closed 1 year ago.
I'm trying to force users to pick a unique username and returning an error message if they don't. All other validation (password matching, etc.) is working but validating an unused username just returns ID Registration failed message.
I've updated this with the HTML as requested.
I just want it to tell the user the errors I've outlined in those cases.
<?php

assign $idcount with 0 first before using and then in the if condition use ($idcoun>=1)
And According to your logic if the userid and email exist also then also you are inserting the data which make no sense according to your need
Enclose your INSERT block in:
if( $fmsg == "" ) { ..to here.. }
So that if there was an error, no record will be inserted to database, and error will be displayed.
Add action attribute to form tag like:
<form class="form-signin" method="POST" action="">
It is required in some versions of html not html5.

This is my kys_DbConnect.php
<?php
$serverName = "localhost";
$username = "jois";
$password = "iluvcoding";
$db_name = "kys_userdata";
$con = new mysqli($serverName,$username,$password,$db_name);
if($con->connect_error){
echo "Connection Error";
}
?>
I don't know why but it print's nothing nor redirects to index.html (index.html exists). How can I figure out what's wrong with my code?
