please can someone help me with this code? It shows all the users’ info but i need it to show only the info of the logged user.
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "username";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT AEG FROM users";
$result = $conn->query($sql);
if ($result->num_rows > 3) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo "id: " . $row["AEG"]. "<br>";
}
} else {
echo "0 results";
}
$conn->close();
?>
Upon login, store the email/username/id in a $_SESSION variable;
$_SESSION['email'] = $email; // in this example I used email
Then on your file, you can access session variables using $_SESSION['variable'] and use it on your sql statement;
My modifications are the ones with comments.
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "username";
/*Store session data in a variable*/
$email = $_SESSION['email'];
/**********************************/
$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
/*Add where clause to your sql statement*/
$sql = "SELECT AEG FROM users WHERE email ='".$email."'";
/****************************************/
$result = $conn->query($sql);
if ($result->num_rows > 3) {
while($row = $result->fetch_assoc()) {
echo "id: " . $row["AEG"]. "<br>";
}
} else {
echo "0 results";
}
$conn->close();
?>
Try this one if you are having 4 user then it is showing only one
if($result->num_rows > 0)
{
while($row = $result->fetch_assoc())
{
echo "id: " . $row["AEG"]. "<br>";
}
}
else
{
echo "0 results";
}
I've recently started learning functional programming in php, I can't figure out why isn't this working.
I have a separate file called 'functions.php' and I'm trying to call a function in it from index file.
functions.php:
function connectSql() {
$servername = "";
$username = "";
$password = "";
$dbname = "";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Yhteys katkesi: " . $conn->
}
}
function displayPublic() {
connectSql();
$sql = "SELECT * FROM projects WHERE public == true ORDER BY dateStarted DESC";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()){
echo "Project found";
}
} else {
echo "Ei tuloksia";
}
$conn->close();
}
index.php:
include 'functions.php';
displayPublic();
you are not returning the $conn
try
function connectSql() {
$servername = "";
$username = "";
$password = "";
$dbname = "";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Yhteys katkesi: " . $conn->connect_error);
} else {
return $conn;
}
}
function displayPublic() {
$conn = connectSql();
$sql = "SELECT * FROM projects WHERE public == true ORDER BY dateStarted DESC";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()){
echo "Project found";
}
} else {
echo "Ei tuloksia";
}
$conn->close();
}
or make $conn a global variable
<?php
$conn;
function connectSql() {
$servername = "";
$username = "";
$password = "";
$dbname = "";
global $conn;
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Yhteys katkesi: " . $conn->connect_error);
}
}
function displayPublic() {
connectSql();
global $conn;
$sql = "SELECT * FROM projects WHERE public == true ORDER BY dateStarted DESC";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()){
echo "Project found";
}
} else {
echo "Ei tuloksia";
}
$conn->close();
}
I'm trying to update db record using the code below. Even if the redirection is done, the record isn't being updated as it should be. any tips please?
<?php
session_start();
?>
<?php
$servername = "localhost";
$username = "root";
$password = "root";
$dbname = "Mydatabase";
$id = $_GET["session_id()"];
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "UPDATE leads SET first_name='hola' WHERE id = '$id'";
if ($conn->query($sql) === TRUE) {
header( "thank-you.php" ); die;
} else {
echo "Error updating record: " . $conn->error;
}
$conn->close();
?>
This one causes the problem.
$id = $_GET["session_id()"];
session_id() itself is a PHP function. No need for quoting. Just remove the quotes and it should be fine.
$id = $_GET[session_id()];
What I wan't to do is create buttons that are automatically generated from the database. So when I add a new record in the database the button is created Is this possible with a loop? So yes how do I create the button.
This is what I have so far:
<?php
$servername = "localhost";
$username = "root";
$password = "Iamthebest1009";
$dbname = "dktp";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT * FROM theme";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo "". $row["theme_name"]. "<br>";
}
} else {
echo "no results";
}
$conn->close();
?>
Yes it is possible. you need to echo html
<?php
$servername = "localhost";
$username = "root";
$password = "Iamthebest1009";
$dbname = "dktp";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT * FROM theme";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
$your_url ="https://www.google.com";
echo "". $row["theme_name"]. "<br>";
echo '<input type="button" name="' . $row["theme_name"]. '" value="'. $row["theme_name"].'">';
}
} else {
echo "no results";
}
$conn->close();
?>
I've following code of a function in a PHP file titled sample.php :
function deleteValue($value) {
$servername = "localhost";
$username = "root";
$password = "jumbo";
$dbname = "demo";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "DELETE FROM user WHERE value = '$value'";
if ($conn->query($sql) === TRUE) {
$conn->close();
return true;
} else {
$conn->close();
return false;
}
}
Actually, in this file(sample.php) there are too many such functions which repeats the following database connectivity code :
$servername = "localhost";
$username = "root";
$password = "jumbo";
$dbname = "demo";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
Then, I created one file titled db.php in the same folder and added the above code to it. Using require_once('db.php'); at the beginning of file 'sample.php'I included the file to the above code. Finally the code appeared as follows :
require_once('db.php');
function deleteValue($value) {
$sql = "DELETE FROM user WHERE value = '$value'";
if ($conn->query($sql) === TRUE) {
$conn->close();
return true;
} else {
$conn->close();
return false;
}
}
Now it's giving me 500 Internal Server error.
Even instead of including the file I tried by pasting the whole code from db.php at the beginning of file sample.php as follows but still I get 500 Internal Server Error.
$servername = "localhost";
$username = "root";
$password = "jumbo";
$dbname = "demo";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
function deleteValue($value) {
$sql = "DELETE FROM user WHERE value = '$value'";
if ($conn->query($sql) === TRUE) {
$conn->close();
return true;
} else {
$conn->close();
return false;
}
}
Can someone please correct the mistake I'm making in my code?
Thanks in advance.
I will suggest you that in db_config.php file you should use only database config and functions like this:
$servername = "localhost";
$username = "root";
$password = "jumbo";
$dbname = "jumbo_jet";
$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_errno) {
echo "Failed to connect to MySQL: (" . $conn->connect_errno . ") " . $conn->connect_error;
}
And in common.php use code like this:
require_once("db_config.php");
function deleteToken($receivedToken) {
global $conn;
$sql = "DELETE FROM user_login WHERE token = '$receivedToken'";
if ($conn->query($sql) === TRUE) {
return true;
}
return false;
}
I hope it will work for you. If anything else then let me know.
