The below is a simple script in order to remove information from a table which works fine, however this does not redirect to where I need it to go. Any ideas? I have also tried using die(); etc afterwards.
<?php
$dbservername = "xxxxx";
$dbusername = "xxxxx";
$dbpassword = "xxxxx";
$conn = mysql_connect($dbservername, $dbusername, $dbpassword);
$db = mysql_select_db("sxxxxx", $conn);
if (!$conn) { die('Could not connect: ' . mysql_error()); }
?>
<?php
session_start();
include"connect_db.php"; (this include, includes the above connection to db)
$content_id=$_GET['content_id'];
$username=$_SESSION['username'];
$sql = "DELETE FROM `user_blogs` WHERE `id`='".$content_id."' AND `username`='".$username."'";
$res = mysql_query($sql) or die(mysql_error());
header("location: user_page.php");
?>
try this might be the conditional problem...
$res = mysql_query($sql) or die(mysql_error());
if($res){
header("location: user_page.php");
}else{}

I am making a profile page in which I want the user's email to be displayed. I thought this would be quite a simple code that could be achieved using the select function from the database. However, this only works for one string and I cannot seem to figure out why.
This is my original code
session_start();
$_SESSION["user"] = $username;
$_SESSION["pass"] = $password;
$_SESSION["email"] = $email;
$connection = mysqli_connect ("localhost", "root", "", "picshare");
if ($connection ->connect_error) {
die("Connection failed: " . $connection->connect_error);
}else{
$query = mysqli_query($connection, "SELECT email FROM login WHERE username='".$_SESSION["user"]."'");
$field = mysqli_fetch_assoc($query);
if (!$query)
{
die('Error: ' . mysqli_error($con));
}if(mysqli_num_rows($query) > 0){
$field = mysqli_fetch_assoc($query);
}else{
echo "error";
$conn->close();
}}
When I try and echo $field, nothing was echoed
<p class ="right uc"><?php echo($field['email']);?></p>
I retried the code, but instead of using a session, I made a variable
$host = "localhost";
$dbusername = "root";
$dbpassword = "";
$dbname = "picshare";
$user = 'Eniola Olaogun';
$conn = new mysqli ($host, $dbusername, $dbpassword, $dbname);
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}else{
$query = mysqli_query($conn, "SELECT email FROM login WHERE username='".$user."'");
$field = mysqli_fetch_assoc($query);
if (!$query)
{
die('Error: ' . mysqli_error($con));
}if(mysqli_num_rows($query) > 0){
$field = mysqli_fetch_assoc($query);
echo($field['email']);
}else{
echo "error";
$conn->close();
This code displayed the email, and so I proceeded to change the $user variable to another name and the original problem occurred where nothing was echoed.
I went back to the original code and I logged in as Eniola Olaogun and the email was echoed, but as soon as I changed the person I logged in as, no email was echoed.
I am not sure why I am experiencing this problem and some help would be greatly appreciated
$host = "localhost";
$dbusername = "root";
$dbpassword = "";
$dbname = "picshare";
$user = 'Eniola Olaogun';
$conn = new mysqli ($host, $dbusername, $dbpassword, $dbname);
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
else {
$sql = "SELECT email FROM login WHERE username= {$user}";
$result = $conn->query($sql);
if($result->num_rows > 0) {
$row = mysqli_fetch_array($result,MYSQLI_ASSOC);
echo($row['email']);
}
else {
echo "error";
$conn->close();
error connecting to mysql database through crazy domains
It sounds like it is a permission issue based on the user you're logging in as.
Test it with a 'root' user password that has global access and then troubleshoot and isolate it from there. I'm betting you will find it then.
Pretty much impossible for me to test this remotely since I don't have your DB schema and user accounts to validate with.
I want to open a count in a php file in order to get the first register
<?php
include_once('dbConfig.php');
session_start();
$id_persona= $_SESSION["id"];
$query = "SELECT COUNT( * ) AS alias1 FROM `desayuno_ingreso` WHERE `desayuno_ingreso`.`id` =88757532";
echo $query;
$resultset = mysqli_query($conn,$query);
if(mysqli_num_rows($resultset) > 0){
$k=0;
while ($fila = mysqli_fetch_assoc($resultset)) {
$lat[$k]= $fila['alias1'];
$k=$k+1;
}
}
echo $lat[0];
?>
I tried in every single way I know (Every way worked for me before). However, it doesn't working right now.
I'm no sure what I'm doing wrong.

This is the dbConfig.php file:
<?php
$dbHost = 'localhost';
$dbUser = 'root';
$dbPass = 'mypassword';
$dbName = 'app';
$conn = mysqli_connect($dbHost,$dbUser,$dbPass,$dbName);
if(!$conn){
die("Database connection failed: " . mysqli_connect_error());
}
?>
include_once 'dbfunction.php';
getDbConnect();
mysqli_query("DELETE FROM crewlist WHERE id = $_GET[crew_id]") or die (mysqli_error());
echo 'Delete success';
header ('Location: crewlisting.php');
This code doesn't work, however when I replace the crew_id with the actual primary key via hard coding the delete function works
Use this (MySQLi Procedural)
In dbfunction.php should be
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";
// Create connection
$conn = mysqli_connect($servername, $username, $password, $dbname);
// Check connection
if (!$conn)
{
die("Connection failed: " . mysqli_connect_error());
}
?>
and insert page should be
<?
include ("dbfunction.php"); //include db connection
$id = $_REQUEST['crew_id'];
$sql = "DELETE FROM crewlist WHERE id = '$id' ";
if (mysqli_query($conn, $sql))
{
echo "Record deleted successfully";
}
else
{
echo "Error deleting record: " . mysqli_error($conn);
}
mysqli_close($conn);
?>
Errors are
There is no function define in getDbConnect()
If you are confusing with 'and " then split the functions
$id = $_REQUEST['crew_id'];
$sql = "DELETE FROM crewlist WHERE id = '$id' ";
Use mysqli_query and mysqli_error in correct format
and error in mysqli_query, You are not passing connection to MySQLi
When ever database part is Finished, Close connection mysqli_close($conn);
Correct your query:
mysqli_query("DELETE FROM crewlist WHERE id ='".$_GET['crew_id']."'") or die('Error: ' . mysqli_error());
This is my login code, cant figure out whats wrong ( the last if, always goes to the last else ). i tried everything but still no luck.
<?php
error_reporting(E_ALL & ~E_NOTICE);
session_start();
if($_POST['submit']){
include_once("connection.php");
$username = strip_tags($_POST['username']);
$password = strip_tags($_POST['password']);
$sql = "SELECT id, username, password FROM user WHERE username = '$username' AND password = '$password'";
$query = mysqli_query($connection, $sql);
if($query){
$row = mysqli_fetch_row($query);
$userId = $row[0];
$dbUsername = $row[1];
$dbPassword = $row[3];
}
if ($username = $dbUsername && $password == $dbPassword) {
$_SESSION['username'] = $username;
$_SESSION['id'] = $userId;
header('Location: users.php');
}else {
header('Location: error.php');
}
}
?>
and thas my connection code
<?php
$connection = mysql_connect('localhost', 'root', '');
if (!$connection){
die("Database Connection Failed" . mysql_error());
}
$select_db = mysql_select_db('login');
if (!$select_db){
die("Database Selection Failed" . mysql_error());
}
?>
You are going to kick yourself... you have only a single = in your if.
if ($username = $dbUsername && $password == $dbPassword) {
Should be
if ($username == $dbUsername && $password == $dbPassword) {
The single = turns it into an assignment instead of a comparison.
Beyond that you are actually doing the comparison twice; once in SQL to get back the username and password, the second time in PHP. If your query returns the user id, you already know that the username/password did the trick.
You are also mixing mysql_connect and mysqli_query (and mysql_fetch_row). As the others have suggested, you need to move to the mysqli class or to PDO. But to get you going, you need to at very least change mysqli_query to mysql_query and mysqli_fetch_row to mysql_fetch_row.
Use mysql_query($connection, $sql) instead of mysqli_query($connection, $sql);
as you are using mysql_connect
I am currently having a problem in which the login page to my website goes directly to the homepage without checking the users credentials stored in my data base. The code I use to register the users works just fine but for some reason I cant get this working properly.
<?php
session_start();
$dbhost = 'localhost:3036';
$dbuser = 'mredd';
$dbpass = 'csc255pass';
$conn = mysql_connect($dbhost, $dbuser, $dbpass);
//mysql_select_db( 'USERS_DB' );
if(! $conn )
{
die('Could not connect: ' . mysql_error());
}
$db_selected = mysql_select_db("USERS_DB",$conn);
if (!$db_selected)
{
die ("Can\'t use test_db : " . mysql_error());
}
if ($_SERVER["REQUEST_METHOD"] == "POST")
{
$user = $_POST['username'];
$pass = $_POST['password'];
$sql="SELECT * FROM log_tbl Where username='$user' AND password='$pass'";
$retval = mysql_query( $sql, $conn );
$row = mysql_num_rows($retval);
if ($row == 1)
$_SESSION['user'] = $user;
header("Location: homepage.php");
}
?>
Doh! You fell into the trap of not using brackets with your If statement. The final chunk should read
$sql="SELECT * FROM log_tbl Where username='$user' AND password='$pass'";
$retval = mysql_query( $sql, $conn );
$row = mysql_num_rows($retval);
if ($row == 1) { //need this bracket
$_SESSION['user'] = $user;
header("Location: homepage.php");
} //and this one
} // this closes the 'POST' clause
?>
The code you wrote will only set the session if the row is returned, and will ALWAYS redirect to homepage.php. An If statement without brackets only controls the next command.
