trying to do SELECT in php but i get - php

So I got a nifty little bit of code set to run along and find me information when I give it a certain KittenID but its not working at all, I am sad. And oh so tired, Can anyone tell me where I have gone wrong? and yes I do have:
<?php
date_default_timezone_set('America/New_York');
//If statements:
//find:
date_default_timezone_set('America/New_York');
if(isset($_POST['Find']))
{
$connection = mysql_connect("ocelot.aul.fiu.edu","userName","password");
// Check connection
if (!$connection)
{
echo "Connection failed: " . mysql_connect_error();
}
else
{
//select a database
$dbName="spr15_xgotz001";
$db_selected = mysql_select_db($dbName, $connection);
//confirm connection to database
if (!$db_selected)
{
die ('Can\'t use $dbName : ' . mysql_error());
}
else
{
$result = mysql_query($connection,"SELECT * FROM Kittenz WHERE KittenID =<?php$_POST[KittenID]?>;)
while($row = mysql_fetch_array($result))
{
$Name = $row['Name'];
$KittenID = $row['KittenID'];
$KittenAge = $row['KittenAge'];
$Email = $row['Email'];
$Comments = $row['Comments'];
$Gender = $row['Gender'];
$Personality = $row['Personality'];
$Activity = $row['Activity'];
echo $row['Comments'];
}
}
}
mysql_close($connection);
}
?>

Use
$result = mysql_query($connection,"SELECT * FROM Kittenz WHERE KittenID = " .$_POST['KittenID']);
instead of
$result = mysql_query($connection,"SELECT * FROM Kittenz WHERE KittenID =<?php$_POST[KittenID]?>;)
Note: Please use mysqli_ for your future projects

You need to privide more context. How are you setting the $_GET['id'].. is it in fact being stored as $_GET['KittenID'] (e.g. https://yoursite.com?view&KittenID=1). If so...
You can set a variable and declare the 'KittenID'
$kittenid = $_POST['KittenID'];
$result = mysql_query($connection,"SELECT * FROM Kittenz WHERE KittenID = $kittenid");
I suggest providing more context. What error are you getting? What do your parameters look like?

Use
$result = mysql_query($connection,"SELECT * FROM Kittenz WHERE KittenID = " .$_SERVER['KittenID']);
instead of
$result = mysql_query($connection,"SELECT * FROM Kittenz WHERE KittenID =<?php$_POST[KittenID]?>;)

Table 'databasename.info' doesn't exist

So I installed this jackpot script with a layout and everything and within the jackpot script there was a set.php file which I tried to set up, it looked like this:
<?php
$sitename = "csgoxd.net";
$link = #mysql_connect("localhost:3306", "csgoxdne", "thisisasecretpassword");
$db_selected = mysql_select_db('csgoxdne_csgoxddb', $link);
mysql_query("SET NAMES utf8");
function fetchinfo($rowname,$tablename,$finder,$findervalue) {
if($finder == "1") $result = mysql_query("SELECT $rowname FROM $tablename");
else $result = mysql_query("SELECT $rowname FROM $tablename WHERE `$finder`='$findervalue'") or die (mysql_error());
$row = mysql_fetch_assoc($result);
return $row[$rowname];
}
?>
So I'm new when it comes to coding in general (I know some basic stuff but that's it) so basically I'm not sure if I'm supposed to fill out more of this file because I get this error on my website.
"Table 'csgoxdne_csgoxddb.info' doesn't exist"
I'm new to this and I'm trying to learn so help is much appreciated.
You should use MySQLi to make use of its advantages it offers over MySQL. You can see more here.
The script you have isn't all too bad, but it does need some tweaking. It's vulnerable to injection like Marc B said. I'm going to assume that csgoxdne_csgoxddb is your table name.
Try this:
<?php
$mysqli = new mysqli("localhost:3306", "csgoxdne", "thisisasecretpassword");
if (mysqli -> error){ print ("Error connecting! Message: ".$mysqli->error); }
mysqli_set_charset($mysqli, 'utf8');
function fetchinfo($rowname, $tablename, $finder, $findervalue) {
if ($finder == "1") {
$query = "SELECT * FROM $tablename WHERE rowname = '$rowname'";
$result = mysqli_query($mysqli, $query);
} else {
$query = "SELECT * FROM $tablename WHERE `$finder`='$findervalue'";
if (!$query) {
die('Invalid query: ' . $mysqli->error);
}
$result = mysqli_query($mysqli, $query);
}
return $result;
}
?>
Oh and make sure the port number on your localhost is correct.
Also to go through the values of result you can use:
if (mysqli_num_rows($result) > 0) {
while ($row = mysqli_fetch_array($result)) {
#do things
}
}

php mysqli not working

I am making a chat application and this is the part that checks for new additions.
<?php
$servername = "*";
$username = "*";
$password = "****";
$dbname = "*";
$conn = mysqli_connect($servername, $username, $password, $dbname);
// Check connection
if (mysqli_connect_error($conn)) {
die("Connection failed: " . mysqli_connect_error($conn));
}
$id = $_GET['id'];
$sql = "SELECT position, user, comment,time FROM chat WHERE position > $id";
$result = mysqli_query($conn,$sql);
if (mysqli_num_rows() > 0) {
// output data of each row
while($row = mysqli_fetch_assoc($result)) {
$row2 = mysqli_fetch_assoc(mysqli_query($conn,"SELECT * FROM login WHERE username=".$row['user']));
$userImage = $row2["avatar"];
echo "<div class='container-fluid well'><p class='left'>"."<img class='img-circle zoom' src='/profile_images/".
$userImage
."' style='width:32px;height:32px;'>".$row["user"]. ": " . $row["comment"]. "</p><h4><small class='right'> at ".$row['time']."</small></h4></div>";
}
}
mysqli_close($conn);
?>
it was working until I changed the line
$row2 = mysqli_fetch_assoc(mysqli_query($conn,"SELECT * FROM login WHERE username=".$row['user']));
Help would be appreciated.
Update:
this is my html:
There is more. but this is the most important
<div id='newchat'></div>
<script>
$(document).ready(function(){
getChat();
var id = <?php echo $id ?>;
function getChat(){
setTimeout(getChat,1000);
$.get("getChat.php?id="+id,function( text ) {
if (text != ""){
id ++;
$( "#newchat" ).prepend( text );
}
});
}
});
</script>
Try this query :
$row2 = mysqli_fetch_assoc(mysqli_query($conn,"SELECT * FROM login WHERE username='{$row['user']}'"));
Side note : Your query is unsafe. Read this
How can I prevent SQL injection in PHP?.
you forget 2 '
$row2 = mysqli_fetch_assoc(mysqli_query($conn,"SELECT * FROM login WHERE
username='".$row['user']."'"));
Simply use this query:
"SELECT * FROM login WHERE username='".$row['user']."'"
instead of
"SELECT * FROM login WHERE username=".$row['user']
and if you want a simple query then use:
$usr = $row['user'];
$row2 = mysqli_fetch_assoc(mysqli_query($conn,"SELECT * FROM
login WHERE username=$usr"));
It'll definitely work.
Write your query as below:-
$sql = "SELECT * FROM login WHERE username='{$row['user']}'";
mysqli_fetch_assoc(mysqli_query($conn,$sql));
Hope it will help you :)

Adding parameters to an already working webservice

I have the following already working great, but would like to add a parameter as this returns the whole data set.
<?php
$mysql_db_hostname = "localhost";
$mysql_db_user = "00000";
$mysql_db_password = "00000";
$mysql_db_database = "000000";
$con = #mysqli_connect($mysql_db_hostname, $mysql_db_user, $mysql_db_password,
$mysql_db_database);
if (!$con) {
trigger_error('Could not connect to MySQL: ' . mysqli_connect_error());
}
$var = array();
$sql = "SELECT * FROM mns";
$result = mysqli_query($con, $sql);
while($obj = mysqli_fetch_object($result)) {
$var[] = $obj;
}
echo '{"mns":'.json_encode($var).'}';
?>
For clarification, I was hoping to add a parameter in the url that is passed through to the php so that I get specific records. For example, if there is a field called [Customer], I would like to pass a customer id to it.

PHP infinite loop issue

I can get the correct code to work, but i want to be able to use objects and methods, which doesn't work. The same entry in the database is repeated until the query crashes. I saw other people that had queries inside of the while statement, but i thought that the method i am using should only query the statement once, but im likely wrong. Thanks.
<?php
include '/functions/MySQL.php';
$MySQL = new MySQL;
$con = mysqli_connect("host","user","password","db");
$result = mysqli_query($con,"SELECT * FROM reportLogger WHERE Moderator='jackginger'");
while($row = mysqli_fetch_array($MySQL->getReports('jackginger'))) {
$time = $row['Time'];
$moderator = $row['Moderator'];
$reason = $row['Reason'];
// Now for each looped row
echo "<tr><td>".$time."</td><td>".$moderator."</td><td>".$reason."</td></tr>";
}
?>
Seperate class
public function __construct(){
$this->con = mysqli_connect("localhost","root","pass","Minecraft");
// Check connection
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
}
public function getUUID($username) {
$result = mysqli_query($this->con,"SELECT UUID FROM loginLogger WHERE Username='" . $username . "'");
return mysqli_fetch_array($result)[0];
}
public function getReports($username) {
$result = mysqli_query($this->con,"SELECT * FROM reportLogger WHERE UUID='" . $this->getUUID($username) . "'");
return $result;
}
Each time you call while($row = mysqli_fetch_array($MySQL->getReports('jackginger'))) you are making a new query, so it's fetching the samething over and over again.
a solution could be:
<?php
include '/functions/MySQL.php';
$MySQL = new MySQL;
$con = mysqli_connect("host","user","password","db");
$result = mysqli_query($con,"SELECT * FROM reportLogger WHERE Moderator='jackginger'");
$store = $MySQL->getReports('jackginger');
while($row = mysqli_fetch_array($store)) {
$time = $row['Time'];
$moderator = $row['Moderator'];
$reason = $row['Reason'];
// Now for each looped row
echo "<tr><td>".$time."</td><td>".$moderator."</td><td>".$reason."</td></tr>";
}
?>

Problems deleting File PHP

This is my code to pull information from my sql database and then I want to delete the .txt files in each directory, but I can't seem to figure out why it won't delete the files.
<?php
session_start();
$user = $_SESSION['SESS_USERNAME'];
$id = array();
$id = $_POST['selected'];
//Include database connection details
require_once('config_order.php');
//Connect to mysql server
$link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);
if (!$link) {
die('Failed to connect to server: ' . mysql_error());
}
//Select database
$db = mysql_select_db(DB_DATABASE);
if (!$db) {
die("Unable to select database");
}
//Create query
$query = mysql_query("SELECT * FROM `PropertyInfo` WHERE `order_number` = '$id[0]'");
// display query results
while ($row = mysql_fetch_array($query)) {
$c_name = $row['clientname'];
$sitestreet = $row['sitestreet'];
$inspector = $row['inspector'];
}
mysql_close($link);
$client_name = str_replace(" ", "_", $c_name);
$site_street = str_replace(" ", "_", $sitestreet);
$client_name = "{$client_name}.txt";
$site_street = "{$site_street}.txt";
$client_path = "/var/www/vhosts/default/htdocs/Members/$user/$inspector/Orders/Clients";
$inspection_path = "/var/www/vhosts/default/htdocs/Members/$user/$inspector/Orders/Inspections";
if (unlink($client_path . "/" . $client_name)) {
echo 'File Deleted';
} else {
echo 'File could not be deleted';
}
?>
I think this is because your while loop is overwriting the $c_name, $sitestreet and $inspector variables. This means you will only ever delete the last file.
Is this what you were trying to do? (Edited Again...)
$query = mysql_query("SELECT * FROM `PropertyInfo` WHERE `order_number` IN (".mysql_real_escape_string(implode(',',$id)).")");
while ($row = mysql_fetch_array($query)) {
$inspector = $row['inspector'];
$client_name = str_replace(" ", "_", $row['clientname']).'.txt';
$site_street = str_replace(" ", "_", $row['sitestreet']).'.txt';
$client_path = "/var/www/vhosts/default/htdocs/Members/$user/$inspector/Orders/Clients";
$inspection_path = "/var/www/vhosts/default/htdocs/Members/$user/$inspector/Orders/Inspections";
if (!file_exists($client_path.'/'.$client_name)) {
echo "File $client_path/$client_name does not exist!\n";
} else echo (unlink($client_path.'/'.$client_name)) ? "File $client_path/$client_name was deleted\n" : "File $client_path/$client_name could not be deleted\n";
}
mysql_close($link);
Try some extra debugging:
$realpath = $client_path . '/' . $client_name;
if (file_exists($realpath)) {
if (is_writable($realpath)) {
if (unlink($realpath)) {
echo "$realpath deleted";
} else {
echo "Unable to delete $realpath";
}
} else {
echo "$realpath is not writable";
}
} else {
echo "$realpath does not exist";
}
On first glance, this is a problem, if $_POST['selected'] is not an array:
$id = array();
$id = $_POST['selected'];
...
$query = mysql_query("SELECT * FROM `PropertyInfo` WHERE `order_number` = '$id[0]'");
You are instantiating $id as an empty array, then overwriting it with $_POST['selected'], so $id[0] is the first character of the string $id.
For example, if $_POST['selected'] is 12345:
"SELECT * FROM `PropertyInfo` WHERE `order_number` = '$id[0]'"
is equivalent to:
"SELECT * FROM `PropertyInfo` WHERE `order_number` = '1'"
Either don't try to access it with an index or do $id[] = $_POST['selected']; to add the element onto the $id array instead.
Whether that is an array or not, you do need to either sanitize that input before you insert it into the query or use prepared statements, though!
