How can i get mysql_result() to work - mysql

I am new to programming, I've been trying to create a hit_counter for a demo site I am developing but I keep getting an error for the MySQL_result() function.
$user_ip = $_SERVER['REMOTE_ADDR'];
function ip_exists($ip) {
include 'include.php';
global $user_ip;
$query = "SELECT `ip` FROM `ip` WHERE`ip`= '$user_ip'";
$mysql_run = mysqli_query($con, $query);
$query_num_rows = mysqli_num_rows($mysql_run);
if ($query_num_rows == 0) {
return false;
} else if ($query_num_rows >= 1) {
return true;
}
}
function ip_add($ip) {
include 'include.php';
$query = "INSERT INTO `ip` VALUES('$ip')";
$query_run = mysqli_query($con, $query);
}
function update_count() {
include 'include.php';
$query = "SELECT `hits` FROM `hit_count`";
if ($query_run = mysqli_query($con, $query)) {
$count = mysql_result($query_run, 0, 'hits');
$count_inc = $count + 1;
$query_update = "UPDATE ``hit_count` SET `hits`= '$count_inc'";
$query_update_run = mysqli_query($con, $query_update);
}
}
if (!ip_exists($user_ip)) {
update_count();
ip_add($user_ip);
}

You are mixing mysql_*() and mysqli_*() functions; they belong to different MySQL extensions and cannot be interchanged. Since the rest of your code uses mysqli, make sure you don't use any mysql_*() function. The old MySQL PHP extension (that provides the mysql_*() functions) has been deprecated in PHP 5.5 and completely removed in PHP 7.
Using MySQLi, the equivalent of $count = mysql_result($query_run, 0, 'hits') is:
$row = mysqli_fetch_assoc($query_run);
$count = $row['hits'];

WordPress and PHP | Check if row exists in database if yes don't insert data

I'm fairly new to WordPress and SQL. I have a contact form that I want to have the data be submitted to my WordPress database but only if the data that has been entered has not been entered before.
This is what i have so far, which sends data to my database when form is submitted.
if(isset($_POST['contact_us'])) {
$invalidContact = "<h5 class='invalidBooking'> Nope try again</h5>";
$successContact = "<h5 class='invalidBooking'> Message Sent!</h5>";
$table_name='contact_table';
global $wpdb;
$contact_name = esc_attr($_POST['contact_name']);
$contact_email = sanitize_email($_POST['contact_email']);
$subject = esc_attr($_POST['subject']);
$message = esc_attr($_POST['message']);
$error= array();
if (empty($contact_name)) {
$error['name_invalid']= "Name required";
}
if (empty($contact_email)){
$error['email_invaild']= "Email required";
}
// Im guessing some code here to check if row exists in database
if (count($error) >= 1) {
echo $invalid;
}
if (count($error) == 0) {
$data_array=array(
'Contact_Name'=>$contact_name,
'Contact_Email'=> $contact_email,
'Contact_Subject'=> $subject,
'Contact_Message'=> $message,
);
$rowResult=$wpdb->insert($table_name, $data_array,$format=NULL);
echo $successContact;
}
}
You may try this code
if (count($error) == 0) {
$data_array=array(
'Contact_Name'=>$contact_name,
'Contact_Email'=> $contact_email,
'Contact_Subject'=> $subject,
'Contact_Message'=> $message,
);
$query = "SELECT * FROM $table_name WHERE 'Contact_Name'= '$contact_name' AND 'Contact_Email' = '$contact_email' AND 'Contact_Subject' = '$subject' AND 'Contact_Message' = '$message'";
$query_results = $wpdb->get_results($query);
if(count($query_results) == 0) {
$rowResult=$wpdb->insert($table_name, $data_array,$format=NULL);
}
}
Hope this works for you.
fetch data using this code
$query = "SELECT * FROM {$wpdb->prefix}table WHERE column = 1";
echo $query;
$results = $wpdb->get_results($query);
and then you know what to do...

Get data into array using mysql prepared statements

I'm trying to get the function below to return an array of user_ids. Here is the function in php.
function users_following($follower_id)
{
include "dbconn.php";
$stmt = mysqli_prepare($con, "SELECT user_id FROM follo WHERE follower_id = ?");
mysqli_stmt_bind_param($stmt, "i", $follower_id);
mysqli_stmt_execute($stmt);
mysqli_stmt_bind_result($stmt, $following_user_id);
$count = 0;
$user_array = array();
while (mysqli_stmt_fetch($stmt) ) {
$user_array[] = $following_user_id;
$count = $count + 1;
}
mysqli_stmt_close($stmt);
if ($count > 0)
{
return $user_array;
} else {
return false;
}
}
The problem is that the above function just returns the output: 'Array' (without quotes), when I tested with the code below, not the list of user_ids.
$userid_array = users_following($_SESSION["user_id"]);
echo $userid_array;
Can anyone please help me out? If you need additional details, just comment below and I will try to clarify.

Creating Json file from mysql

i can't get more than one return in this json. when the original query returns 90k results.
i can't figure out what's hapening.
also the return i get isn't organized as it should. it return the following
{"material":["R8190300000","0"],"grid":["R8190300000","0"]}
sorry to ask this i have been looking for an answer but couln't get it in the internet.
<?php
$link = mysqli_connect("localhost","blablabla","blablabla","blablabla");
if (mysqli_connect_error()) {
die("Could not connect to database");
}
$query =" SELECT material,grid FROM ZATPN";
if( $result = mysqli_query( $link, $query)){
while ($row = mysqli_fetch_row($result)) {
$resultado['material']=$row;
$resultado['grid']=$row;
}
} else {
echo"doesnt work";
}
file_put_contents("data.json", json_encode($resultado));
?>
The problem is that you are overriding the value for the array keys:
$resultado['material']=$row;
$resultado['grid']=$row;
At the end you will have only the last 2 rows; I suggest you to use something like:
$resultado['material'][] = $row;
$resultado['grid'][] = $row;
This will save you pair rows in $resultado['grid'] and unpaired rows in $resultado['material'];
After the information in comments you can use this code:
$allResults = array();
while ($object = mysqli_fetch_object($result)) {
$resultado['id'] = $object->id;
$resultado['name'] = $object->name;
$resultado['item'] = $object->item;
$resultado['price'] = $object->price;
$allResults[] = $resultado;
}
file_put_contents("data.json", json_encode($allResults));

How to fetch single row/data from Mysql_fetch_array?

I am reading .csv file through PHP using fgetcsv(). Now I am able to fetch I mean read data from .csv file.
Then I need to check SKU column with my fetch result & accordingly have to perform either Insertion Or Updation.
Suppose SKU is already present there, then I have to update my row in table else I need to insert new record.
I have write following code...Plz check n tell me where I am doing mistake-:
<?php
$row = 1;
if (($handle = fopen("localhost/data/htdocs/magento/var/import/Price.csv", "r")) !== FALSE)
{
while (($data = fgetcsv($handle, 8000, ",")) !== FALSE)
{
$num = count($data);
echo "<p> $num fields in line $row: <br /></p>\n";
for ($c=0; $c < $num; $c++)
{
$temp = $data;
$string = implode(";", $temp);
}
$pieces = explode(";", $string);
$col1 = $pieces[0];
$col2 = $pieces[1];
$col3 = $pieces[2];
$col4 = $pieces[3];
$db_name = "magento";
$con = mysql_connect("localhost", "magento", "password");
If (!$con)
{
die('Could not connect: ' . mysql_error());
mysql_close($con);
}
$seldb = mysql_select_db($db_name, $con);
$query_fetch = "SELECT `sku` from `imoprt_prices`";
$result_fetch = mysql_query($query_fetch);
$num_rows = mysql_num_rows($result_fetch);
for($i = 0; $i < $num_rows; $i++)
{
$value = mysql_result($result_fetch, i, 'sku');
if(strcmp('".$value."', '".$col2."') == 0)
{
$flag = 1;
break;
}
else
{
$flag = 0;
break;
}
}
if($flag == 1)
{
$query_upadte = "(UPDATE imoprt_prices SET customer_id= '".$col1."', sku ='".$col2."', price= '".$col3."', website= '".$col4."'
)";
mysql_query($query_upadte);
$row++;
}
if($flag == 0)
{
mysql_query("INSERT INTO `imoprt_prices`(`customer_id`,`sku`,`price`,`website`) VALUES('".$col1."','".$col2."','".$col3."','".$col4."')");
$row++;
}
}
}
?>
If you have an actual UNIQUE index on your imoprt_prices table, you can use the ON DUPLICATE KEY UPDATE syntax and simplify your code a bit to something similar to; (note, can't test, so see as pseudo code)
$db_name = "magento";
$con = mysql_connect("localhost", "magento", "password") or die(mysql_error());
$seldb = mysql_select_db($db_name, $con);
if (($handle = fopen("localhost/data/htdocs/magento/var/import/Price.csv", "r")) !== FALSE)
{
while (($data = fgetcsv($handle, 8000, ",")) !== FALSE)
{
$col1 = $pieces[0];
$col2 = $pieces[1];
$col3 = $pieces[2];
$col4 = $pieces[3];
$query_upadte = "INSERT INTO imoprt_prices (customer_id, sku, price, website) ".
"VALUES('".$col1."','".$col2."','".$col3."','".$col4."') ".
"ON DUPLICATE KEY UPDATE customer_id='".$col1."', price='".$col3.
"',website='".$col4."'";
mysql_query($query_upadte);
}
}
You may also want to either mysql_real_escape_string() or use parameterized queries to make sure there's no ' in your inserted values though. That is always a danger with building sql strings like this.
Simple demo here.
In the following snippet:
$query_upadte = "UPDATE imoprt_prices SET customer_id= '".$col1."', sku ='".$col2."', price= '".$col3."', website= '".$col4."'";
You're trying to update all the rows repeatedly, instead of just updating a single row. This is normally not allowed in MySQL. You need to specify a particular unique ID to be updated.

Was: Grab the last inserted id - mysql Now: Where should we call the last insert id?

Here's the thing, I don't have access to code that inserts data into a given table. However, I need to add related additional data into another table. So, I was thinking about grabbing the last inserted ID and from there... insert the related data into that other table.
Since I don't have access to the statement, I believe that mysql last insert id function will be of no use here.
All the PDO::lastInsertId examples that I see, are also attached to some "insert query" before it, so no use as well.
How can I grab the last inserted ID on the cases were we DON'T have access to the original insert statement ?
Data flow:
It starts here: signup.tpl
Where we have:
onclick="checkoutvalidate();return false"
On the js we have:
function checkoutvalidate() {
$.post("order/index.php", 'a=validatecheckout&'+$("#orderfrm").serialize(),
function(data){
if (data) {
...
} else {
document.orderfrm.submit();
}
});
So, now, let's look for "validatecheckout" into index.php
And we found it:
We can't read along this lines, anything concerning the insertion. The immediately after that I can get is, after the conditional statement - right ?
if ($a=="validatecheckout") {
$errormessage = '';
$productinfo = getProductInfo($pid);
if ($productinfo['type']=='server') {
if (!$hostname) $errormessage .= "<li>".$_LANG['ordererrorservernohostname'];
else {
$result = select_query("tblhosting","COUNT(*)",array("domain"=>$hostname.'.'.$domain,"domainstatus"=>array("sqltype"=>"NEQ","value"=>"Cancelled"),"domainstatus"=>array("sqltype"=>"NEQ","value"=>"Terminated"),"domainstatus"=>array("sqltype"=>"NEQ","value"=>"Fraud")));
$data = mysql_fetch_array($result);
$existingcount = $data[0];
if ($existingcount) $errormessage .= "<li>".$_LANG['ordererrorserverhostnameinuse'];
}
if ((!$ns1prefix)OR(!$ns2prefix)) $errormessage .= "<li>".$_LANG['ordererrorservernonameservers'];
if (!$rootpw) $errormessage .= "<li>".$_LANG['ordererrorservernorootpw'];
}
if (is_array($configoption)) {
foreach ($configoption AS $opid=>$opid2) {
$result = select_query("tblproductconfigoptions","",array("id"=>$opid));
$data = mysql_fetch_array($result);
$optionname = $data["optionname"];
$optiontype = $data["optiontype"];
$qtyminimum = $data["qtyminimum"];
$qtymaximum = $data["qtymaximum"];
if ($optiontype==4) {
$opid2 = (int)$opid2;
if ($opid2<0) $opid2=0;
if ((($qtyminimum)OR($qtymaximum))AND(($opid2<$qtyminimum)OR($opid2>$qtymaximum))) {
$errormessage .= "<li>".sprintf($_LANG['configoptionqtyminmax'],$optionname,$qtyminimum,$qtymaximum);
$opid2=0;
}
}
}
}
$errormessage .= checkCustomFields($customfield);
if (!$_SESSION['uid']) {
if ($_REQUEST['signuptype']=="new") {
$firstname = $_REQUEST['firstname'];
$lastname = $_REQUEST['lastname'];
$companyname = $_REQUEST['companyname'];
$email = $_REQUEST['email'];
$address1 = $_REQUEST['address1'];
$address2 = $_REQUEST['address2'];
$city = $_REQUEST['city'];

$temperrormsg = $errormessage;
$errormessage = $temperrormsg.checkDetailsareValid($firstname,$lastname,$email,$address1,$city,$state,$postcode,$phonenumber,$password1,$password2);
$errormessage .= checkPasswordStrength($password1);
} else {
$username = $_REQUEST['username'];
$password = $_REQUEST['password'];
if (!validateClientLogin($username,$password)) $errormessage .= "<li>".$_LANG['loginincorrect'];
}
}
if (($CONFIG['EnableTOSAccept'])AND(!$_REQUEST['accepttos'])) $errormessage .= "<li>".$_LANG['ordererrortermsofservice'];
$_SESSION['cart']['paymentmethod'] = $_REQUEST['paymentmethod'];
if ($errormessage) echo $_LANG['ordererrorsoccurred']."<br /><ul>".$errormessage."</ul>";
else {
if ($_REQUEST['signuptype']=="new") {
$userid = addClient($firstname,$lastname,$companyname,$email,$address1,$address2,$city,$state,$postcode,$country,$phonenumber,$password1);
}
}
//DO THE DO INSERT_LAST_ID() here ?
}
Thanks in advance,
MEM
After the insert statement you can fire another query:
SELECT LAST_INSERT_ID();
and this will return one row with one column containing the id.
Docs: http://dev.mysql.com/doc/refman/5.0/en/information-functions.html#function_last-insert-id
mysql> SELECT LAST_INSERT_ID();
-> 195
This works per connection so there is no problem if another thread writes into the table. But your SELECT needs to be executed 'RIGHT AFTER'/'As the next query' after the insert query ran
Edit
An example:
$dbConnection = MyMagic::getMeTheDatabase("please");
$oSomeFunkyCode->createThatOneRowInTheDatabase($dbConnection);
$result = $dbConnection->query("SELECT LAST_INSERT_ID();");
// ... fetch that one value and you are good to go
If the column is a simple auto_incrementing integer, you could use SELECT MAX(MyAutoincrementingColumn) FROM MyTable. You might risk selecting a row that has been inserted by another user in the meantime, if your users are not using transactions.
If you don't have access to the last INSERT line, you can make a subquery to find the last inserted id:
select max(id) from <table>
