Issue getting mysqli_query to execute - php

I have written the following function in PHP that has a mysqli_query in it that runs without any errors or exceptions. However, the INSERT INTO statement or $insert variable doesn't seem to be working as expected and I can't figure it out. I realize that posting only a portion of the code might make it difficult to ascertain why it is not working, but I am really looking for confirmation that there are no errors in this function.
Do I need to utilize mysqli_real_escape_string for every url provided? I tried altering $website to $_website to account for this, but it returned nothing.
Just really trying to figure out if there's anything I'm doing wrong here that's prevent the SQL query to work. It returns no error which is making it hard to debug. Thanks in advance!
$jp = mysqli_connect("localhost", "myuser", "password", "mydatabase");
if (!$jp) {
echo "Error: Unable to connect to MySQL." . PHP_EOL;
echo "Debugging errno: " . mysqli_connect_errno() . PHP_EOL;
echo "Debugging error: " . mysqli_connect_error() . PHP_EOL;
exit;
}
function create_distributor( $new_user_id ) {
$errors = new WP_Error();
$error=false;
$errorMsg='';
$logo=true;
$name=addslashes(htmlentities($_REQUEST['name']));
$contact=addslashes(htmlentities($_REQUEST['contact_info']));
$user_info = get_userdata( $new_user_id );
$website = $_POST['website'];
if (stripos($website, "http://") !== 0) //doesn't start with http:// ? , then add it
$website = "http://" . $website;
// $_website = mysqli_real_escape_string($jp, $website); // THIS DOESNT RETURN ANYTHING
$subdir = $user_info->user_nicename; // use nicename because user_login is obfuscated as unverified
$distribpath = 'http://ghq.com/dhdq/'.$subdir;
$ga_code = 'UA-15331916-1'; //default GA code
$logo = 'http://ghq.com/wp-content/themes/CAG/img/ghlogo.jpg'; //default png logo
if(!isset($_REQUEST['name']) || $_REQUEST['name']=='')
{
$error=true;
$errors->add('Distributor Name is required', __('<strong>ERROR</strong>:Distrubutor\'s name was not provided.'));
}
if($error)
{
return($errorMsg);
}
$insert="INSERT INTO distributor (id, name, contact, logo, path, subdir, website, ga_code) VALUES ('".$new_user_id."','".$name."','".$contact."','".$logo."','".$distribpath."','".$subdir."','".$website."','".$ga_code."')";
// var_dump($insert);
// The var_dump print out above is the following SQL Command which if copied and pasted
in phpmyadmin works fine: string(252) "INSERT INTO distributor (id, name, contact,
logo, path, subdir, website, ga_code) VALUES ('1748','test24','','http://ghq.com/wp-content/themes/CAG/img/ghlogo.jpg',
'http://ghq.com/dhdq/test24','test24','','UA-15331916-1')"
mysqli_query($jp, $insert);
if ( false===$insert ) {
printf("error: %s\n", mysqli_error($jp));
}
else {
echo 'done.';
}
if($error)
{
return $errors;
}
else
{
return($id);
}
}

The problem I can see straight off is you are checking your sql variable instead of the query result.
mysqli_query($jp, $insert);
if ( false===$insert ) {
printf("error: %s\n", mysqli_error($jp));
}
else {
echo 'done.';
}
Try changing it to:
$result = mysqli_query($jp, $insert);
if (!$result) {
printf("error: %s\n", mysqli_error($jp));
}else {
echo 'done.';
}
Also whats $jp? it doesn't look like you have assigned it anything. Make sure this is the variable that has your mysqli_connect on it. With your question regarding mysqli_real_escape_string, you should really be utilizing mysqli prepared statements as well. All user input should be sanitized.

Using .php to write data to database

Can someone point the fault in this code? I'm unable to update data to the database. We are sending a text message to the server, and this file here decodes and sets it in the database. But this case over here is not working for some reason. I checked and tried to troubleshoot, but couldn't find a problem.
case 23:
// Gather Variables
$Message = preg_replace("/\s+/","%20", $Message);
$UnixTime = time();
$cycle = explode(":", $Message);
$machine_press = $cycle[0];
$machine_pct_full = $machine_press/20;
$machine_cycles_return = $cycle[1];
$machine_cycles_total = $cycle[2];
// Build SQL Statement to update static values in the machine table
$sql = "UPDATE `machines` SET `machine_last_run`=".$UnixTime.",`machine_press`=".$machine_press.",`machine_pct_full`=".$machine_pct_full.",`machine_cycles_return`=".$machine_cycles_return.",`machine_cycles_total`=".$machine_cycles_total." WHERE `machine_serial`='$MachSerial'";
// Performs the $sql query on the server to update the values
if ($conn->query($sql) === TRUE) {
// echo 'Entry saved successfully<br>';
} else {
echo 'Error: '. $conn->error;
}
$sql = "INSERT INTO `cycles` (`cycle_sequence`,`cycle_timestamp`,`cycle_did`,`cycle_serial`,`cycle_03_INT`,`cycle_14_INT`,`cycle_15_INT`,`cycle_18_INT`)";
$sql = $sql . "VALUES ($SeqNum,$UnixTime,'$siteDID','$MachSerial',$machine_press,$machine_cycles_total,$machine_cycles_return,$machine_pct_full)";
// Performs the $sql query on the server to insert the values
if ($conn->query($sql) === TRUE) {
// echo 'Entry saved successfully<br>';
} else {
echo 'Error: '. $conn->error;
}
break;
More information is required to help you out with your issue.
First, to display errors, edit the index.php file in your Codeigniter
project, update where it says
define('ENVIRONMENT', 'production');
to
define('ENVIRONMENT', 'development');
Then you'll see exactly what the problem is. That way you can provide the information needed to help you.
I just saw that you are inserting strings when not wrapping them in apostrophe '. So you queries should be:
$sql = "UPDATE `machines` SET `machine_last_run`='".$UnixTime."',`machine_press`='".$machine_press."',`machine_pct_full`='".$machine_pct_full."',`machine_cycles_return`='".$machine_cycles_return."',`machine_cycles_total`='".$machine_cycles_total."' WHERE `machine_serial`='$MachSerial'";
and
$sql = "INSERT INTO `cycles` (`cycle_sequence`,`cycle_timestamp`,`cycle_did`,`cycle_serial`,`cycle_03_INT`,`cycle_14_INT`,`cycle_15_INT`,`cycle_18_INT`)";
$sql = $sql . " VALUES ('$SeqNum','$UnixTime','$siteDID','$MachSerial','$machine_press','$machine_cycles_total','$machine_cycles_return','$machine_pct_full')";
For any type of unknown problems I can recommend turning on PHP and SQL errors and use a tool called postman that i use to test my apis. You can mimic requests with any method, headers and parameters and send an "sms" just like your provider or whatever does to your API. You can then see the errors your application throws.
EDIT
I tested your script using a fixed version with ' and db.
$Message = "value1:value2:value3";
$MachSerial = "someSerial";
$SeqNum = "someSeqNo";
$siteDID = "someDID";
$pdo = new PDO('mysql:host=someHost;dbname=someDb', 'someUser', 'somePass');
// Gather Variables
$Message = preg_replace("/\s+/","%20", $Message);
$UnixTime = time();
$cycle = explode(":", $Message);
$machine_press = $cycle[0];
$machine_pct_full = (int)$machine_press/20; // <----- Note the casting to int. Else a warning is thrown.
$machine_cycles_return = $cycle[1];
$machine_cycles_total = $cycle[2];
// Build SQL Statement to update static values in the machine table
$sql = "UPDATE `machines` SET `machine_last_run`='$UnixTime',`machine_press`='$machine_press',`machine_pct_full`='$machine_pct_full',`machine_cycles_return`='$machine_cycles_return',`machine_cycles_total`='$machine_cycles_total' WHERE `machine_serial`='$MachSerial'";
try {
$pdo->query($sql);
} catch (PDOException $e) {
echo 'Query failed: ' . $e->getMessage();
}
$sql = "INSERT INTO `cycles` (`cycle_sequence`,`cycle_timestamp`,`cycle_did`,`cycle_serial`,`cycle_03_INT`,`cycle_14_INT`,`cycle_15_INT`,`cycle_18_INT`)";
$sql = $sql . "VALUES ('$SeqNum','$UnixTime','$siteDID','$MachSerial','$machine_press','$machine_cycles_total','$machine_cycles_return','$machine_pct_full')";
try {
$pdo->query($sql);
} catch (PDOException $e) {
echo 'Query failed: ' . $e->getMessage();
}
It totally works. Got every cycle inserted and machines updated. Before i fixed it by adding wrapping ' i got plenty of errors.
Alright so this is the solution:
i replaced the line:
$Message = preg_replace("/\s+/","%20", $Message);
with:
$Message = preg_replace("/\s+/","", $Message);
This removes all blank spaces in my text message and makes it a single string before breaking and assigning it to different tables in the database.
I understand this wasnt really a problem with the script and no one around would have known the actual problem before answering. and thats why i am posting the solution just to update the team involved here.

PHP: Function no query & return

I hope that someone sharp on PHP can help me with problem, that i really don't understand.
I have 2 scripts. 1: test.php 2:functions.php.
I created a little test where i called a functions in functions.php frim test.php and it work fine. I got a return and it was as expected. I also have a third script register.php where i have a query to a database and that work fine.
So I wanted the query to work as a function written in functions.php
Problem: It seems that it won't make the database query! But there is createt a connection
If I move the exactly same query to test.php, it works! Is there some kind of speciel reason for this? I quit new to php, but knows a little about Java, C, JavaScript, Python.
I have checked that my include / require is all in order.
1: test.php:
<?php
require 'includes/functions.php';
$name = 'testuser';
$_ok = 0;
$_ok = check_username ($name);
printf ( 'Navn i database?: ' . $_ok . '<br>' );
?>
2: functions.php:
<?php
require 'includes/db_connect.php';
// Check connection
if (! $mysqli) {
die ( 'mysqli_init_failed' );
}
if (mysqli_connect_errno ()) {
die ( 'Failed to connect to the Database, Sorry..! errorcode: ' .
mysqli_connect_errno() . ' <br>' . 'Error Type: ' . mysqli_connect_error () );
}
if ($debug_mode_c) {
print ('Connection Established: ' . mysqli_get_host_info ( $mysqli ) . '<br>') ;
print ('session_id: ' . session_id ()) . '<br>';
}
// Set HTML-Header to utf-8.
header ( 'Content Type: text/html; charset=UTF-8' );
// Functions
function check_username($_ok) {
$name = 'testuser';
$prep_stmt = "SELECT username FROM customs WHERE username=? LIMIT 1 ";
$stmt = mysqli_prepare($mysqli, $prep_stmt);
mysqli_stmt_bind_param($stmt, 's', $name);
mysqli_stmt_execute($stmt);
mysqli_stmt_bind_result($stmt, $name_db);
mysqli_stmt_fetch($stmt);
if ($name == $name_db) {
echo "hello";
mysqli_close ($stmt);
$_ok = 0;
} else {
$name = '';
$_ok = 2;
}
mysqli_free_result($stmt);
mysqli_close($stmt);
return $_ok;
}
Maybe found the reason for no query.
Apparently the include script containing establish connection, is not loaded as the function is called in functions.php.
When the query code is in test.php, that include functions.php, all code is read, also the connection for the database.
But even if include 'db_connect' is inside function, it won't work !?! :-(
There is nothing like noquery() function in PHP. please just check it in the include file of the database connection. you will find a user defined function in your include file of the database connection.

Posts Aren't Showing in PHP

I've been stuck on this for two days now. I have set up my own blog and the posts are stored in a database. This page is for grabbing an old post based on it's ID. When I try to retrieve them, everything shows but the actual body.
This is the index in /posts/
<?php
include_once('grabPost.php');
$TEMPLATE_TITLE = "$POST_TITLE";
include_once("../inc/template.html");
?>
Then, this is the grabPost.php.
<?php
error_reporting(-1);
$ID = $_GET['id'];
include_once('connectionMod.php');
$DBConnection = new MySQLi($DB_HOST, $DB_USER, $DB_PASS, $DB_DTBS);
function ReturnError($error){
global $POST_TITLE;
global $POST_BODY;
global $TEMPLATE_CONTENT;
$POST_TITLE="Oops!";
$POST_BODY="<p>It looks like we had an error grabbing your post. The post may have been moved, deleted, or you may have an invalid link. If you <strong>know</strong> this shouldn't be happening, please contact a developer.<br><em>$error</em></p>";
$TEMPLATE_CONTENT = "<h1>$POST_TITLE</h1>\n<hr size='2'>\n$POST_BODY";
}
if($ID == null){
ReturnError("No post ID was provided.");
}
if($stmt = $DBConnection->prepare("SELECT `Title`, `Poster`, `Date`, `Body` FROM `posts` WHERE `ID`=?")){
if(!($stmt->bind_param('i', $ID))){
ReturnError($stmt->error);
}
else if(!($stmt->execute())){
ReturnError($stmt->error);
}
else if(!($stmt->bind_result($POST_TITLE, $POST_NAME, $POST_DATE, $POST_BODY))){
ReturnError($stmt->error);
}
else if(!($stmt->fetch())){
ReturnError($stmt->error);
}
else{
$TEMPLATE_CONTENT = "<h1>$POST_TITLE</h1>\n<small>Posted on $POST_DATE by $POST_NAME</small>\n<hr size='2'>\n$POST_BODY";
}
}
else{
ReturnError($DBConnection->error);
}
?>
Oddly though, you can see the most recent post without issue on the homepage. Any suggestions with what's wrong?
Also, ReturnError() never shows the error. What can I do about it?
Function
function return_error($error){
$post_error = "<h1>Oops!</h1>\n<hr size='2'><br />"
."<p>It looks like we had an error grabbing your post."
."The post may have been moved, deleted, or you may have an invalid link."
."If you <strong>know</strong> this shouldn't be happening, "
."please contact a developer.<br><em>".$error."</em></p>";
return $post_error;
}
Usage:
/* check connection */
if ($DBConnection->connect_errno) {
$error = return_error("Connect failed: %s\n", $DBConnection->connect_error);
echo $error;
die();
}
/* check prepare() */
$stmt = $DBConnection->prepare("SELECT ....FROM `posts` WHERE `ID`=?");
if(!$stmt){
$error = return_error("prepare failed()".$stmt->error);
echo $error;
die();
}
and so forth ... By the way if connection fail or any other fatal error occurs, then die() or exit() is the right thing to do..
Well, I found the fix. I needed to run $stmt->store_result() before $stmt->bind_result() since since the body was a LONGTEXT, I guess this is some issue with MySQL and PHP.

running a mysql stored procedure from php

I must be doing something wrong in this code....
<?
$codeid=$_GET["codeid"];
$tablecode=$_GET["tablecode"];
$description=$_GET["description"];
$code=$_GET["code"];
$groupcode=$_GET["groupcode"];
$t1=$_GET["t1"];
$t2=$_GET["t2"];
$t3=$_GET["t3"];
$mysqli = new mysqli(dbhost,dbuser,dbpass,dbc);
if ($mysqli->connect_error) {
die('Connect Error (' . $mysqli->connect_errno . ') ' . $mysqli->connect_error);
}
$q="call spUpdateCodeTable(?,?,?,?,?,?,?,?)";
$stmt = $mysqli->prepare($q);
$stmt->bind_param($codeid,$tablecode,$description,$code,$groupcode,$t1,$t2,$t3);
$stmt->execute();
mysql_close($mysqli);
?>
Absolutely nothing happens...no error message or any other indication of a problem. It just does not run the procedure. (it's an update/insert routine).
I am using this URL...
updateCodeTable.php?codeid=0&codetable=TABLE&desription=testing2%20entry&code=TEST1&groupcode=gcode&t1=t1&t2=t2&t3=t3
...but, if I run the this query in phpMyAdmin, it runs perfectly....
call spUpdateCodeTable(0,'TABLE','testing2','TEST1','group','','','');
I could include the stored procedure code, but it runs fine anytime I run it directly, but just not running successfully from my php code.
Each mysqli* function/method can fail. Either test the return values and/or switch the reporting mechanism to exceptions, see http://docs.php.net/mysqli-driver.report-mode
<?php
// probably better done with http://docs.php.net/filter but anyway ...just check whether all those parameters are really there
// you are positive that GET is the correct method for this action?
if ( !isset($_GET["codeid"], $_GET["tablecode"], $_GET["description"], $_GET["code"], $_GET["groupcode"], $_GET["t1"], $_GET["t2"], $_GET["t3"]) ) {
// die() is such a crude method
// but bare me, it's just an example....
// see e.g. http://docs.php.net/trigger_error
die('missing parameter');
}
else {
$mysqli = new mysqli(dbhost,dbuser,dbpass,dbc);
if ($mysqli->connect_error) {
die('Connect Error (' . $mysqli->connect_errno . ') ' . $mysqli->connect_error);
}
$q="call spUpdateCodeTable(?,?,?,?,?,?,?,?)";
$stmt = $mysqli->prepare($q);
if ( !$stmt ) {
// $mysqli->error has more info
die('prepare failed');
}
// you have to provide the format of each parameter in the first parameter to bind_param
// I just set them all to strings, better check that
if ( !$stmt->bind_param('ssssssss', $_GET['codeid'], $_GET['tablecode'], $_GET['description'], $_GET['code'], $_GET['groupcode'], $_GET['t1'], $_GET['t2'], $_GET['t3']) ) {
// $stmt->error has more info
die('bind failed');
}
if ( !$stmt->execute() ) {
// $stmt->error has more info
die('execute failed');
}
}
May you have a try to this?
mysqli->query("call spUpdateCodeTable($codeid,'$tablecode',
'$description','$code','$groupcode','$t1','$t2','$t3')");

Querying a database with oop

I have connected to a database for the first time with oop and stright away come up with an issue, below is my code which i'm struggling with:
$q = 'SELECT * FROM test';
$sqli->query($q);
if($sqli->query($q)){
echo "worked";
}
if($sqli->error){
echo $sqli->error;
}
I have checked for errors when connecting to the db and that works fine, but when I run this query I get no output, why? I expected an error or "worked", but have got neither.
Whats happening?
I have put some comments in the source code to help:
$q = 'SELECT * FROM test';
//$sqli is the result of a
//new mysqli("localhost", "user", "password", "database");
$resource = $sqli->query($q); // this returns a resource or false
if(!$resource) {
echo $sqli->error;
die; // do not process further
}
// process the results
$rows = $resource->fetch_all();
if ($rows) { // check if there are rows
echo "worked";
}
else {
echo "query is ok, but there are no rows";
}
You could also use $resource->fetch_object() which returns an object for output. Therefore if you wanted to print specific data from the result set, you would do something like
//table test.Name and test.Country
while ($rowobj = $resource->fetch_object()){
printf ("%s (%s)\n", $rowobj->Name, $rowobj->Country);
}
Good luck,
You could use this method, I hope it's what you are looking for. You will need to define the DB first. Then you can connect in OOP and test the connection is true or exit();
Let me know if this works for you. You can also define the DB in an external file and just do an include(); towards the top of your script for any pages needing connection to the DB.
define("SERVER","IP Address");
define("USER","DB USERNAME");
define("PASSWORD","DB PASSWORD");
define("DATABASE","DB NAME");
// This is for connection
$mysqli = new mysqli(SERVER, USER, PASSWORD, DATABASE);
if ($mysqli->connect_errno) {
echo "Connection to MySQL failed: (" . $mysqli->connect_errno . ") " . $mysqli->connect_error;
exit();
}
