How I See my Result in Select from Where MYSQL using PHP? - php

I have this code, i try to call my data from table database mysql , but didn't see any result. always go to else , not go to the process. what would i do?
<?php
require('connectDB.php');
$nama = $_GET['nama'];
echo $nama;
$query = "SELECT * FROM pesan
WHERE nama = '%" . mysqli_real_escape_string($connection, $nama) . "%'
";
$results = mysqli_query($connection, $query);
$baris = mysqli_num_rows($results);
if (!$results) {
die('Invalid query: ' . mysql_error());
}
if ( $baris > 0) {
while($row = mysqli_fetch_assoc($results)) {
?>
<h3>Nama Mobil : <?php echo $row['mobil'] ?></h3>
<h3>ID Pembelian : <?php echo $row['id']; ?></h3>
<h3>Nama anda : <?php echo $row['nama']; ?></h3>
<h3>Alamat : <?php echo $row['alamat']; ?></h3>
<h3>Tanggal Masuk : <?php echo $row['tgl_masuk']; ?></h3>
<?php
}
}else{
echo "error";
}
?>
What wrong with my code?
Thanks!
im sorry , this is my ConnectDB.php , i include in my html.
<?php
$connection = mysqli_connect('localhost', 'root', '', 'dealermobil');
if (!$connection){
die("Database Connection Failed" . mysqli_error());
}
// $db = new PDO ('mysql:host=localhost;dbname=db_login;charset=utf8mb4','root','');
?>

Your connection check and result check is incorrect.
$connection = mysqli_connect('localhost', 'root', '', 'dealermobil');
if (!$connection){
die("Database Connection Failed" . mysqli_connect_error());
}
Also
$results = mysqli_query($connection, $query);
$baris = mysqli_num_rows($results);
if (!$results) {
die('Invalid query: ' . mysqli_error($connection));
}

use this you are using = it should be LIKE when you are trying to search a field in database.
$query = "SELECT * FROM `pesan` WHERE `nama` LIKE '%". mysqli_real_escape_string($connection, $nama) ."%'";

How to use Insert query in PHP code

I do not understand what is going wrong with code. The result is get is "connected successfully success Query failed". I tried few combinations and I get the same result. Please help me in solving this. Thanks in advance.
<?php
$link = mysql_connect('localhost', 'root1', '')
or die('Could not connect: ' . mysql_error());
if ($link) {
echo 'connected successfully';
}
$l = mysql_select_db('vtflix', $link) or die ('Could not select the database');
if ($l) {
echo ' success';
}
/*$varCNAME = 'John';
$varCONTENT = '4';
$varVID = '1';*/
$sql = "INSERT INTO mpaa(C_Name, ContentRating, V_ID) VALUES ('Jon', 4, 3)";
mysql_query($sql, $link) or die("Query failed");
$que = "SELECT * FROM mpaa";
$query = mysql_query($que, $link);
if (!$query) {
echo 'query failed';
}
while ($sqlrow = mysql_fetch_array($query, MYSQL_ASSOC)) {
$row = $sqlrow['C_Name'];
$nrow = $sqlrow['Content Rating'];
$mrow = $sqlrow['V_ID'];
echo "<br>" . $row . " " . $nrow . " " . $mrow . "<br>";
}
mysql_close($link);
?>
1.Don't use mysql_* library (deprecated from php5 onward + removed from php7) .Use mysqli_* OR PDO.
2.An example of mysqli_*(with your code)is given below:-
<?php
error_reporting(E_ALL); // check all type of error
ini_set('display_errors',1); // display those errors
$link = mysqli_connect('localhost', 'root1', '','vtflix');
if($link){
echo 'connected successfully';
$sql= "INSERT INTO mpaa(C_Name,ContentRating,V_ID) VALUES ('Jon', 4, 3)";
if(mysqli_query($link,$sql)){
$query = "SELECT * FROM mpaa";
$res = mysqli_query($link,$query);
if($res){
while($sqlrow=mysqli_fetch_assoc($query))
{
$row= $sqlrow['C_Name'];
$nrow= $sqlrow['Content Rating'];
$mrow= $sqlrow['V_ID'];
echo "<br>".$row." ".$nrow." ".$mrow."<br>";
}
mysqli_close($link);
}else{
echo die('Query error: ' . mysqli_error($link));
}
}else{
echo die('Query error: ' . mysqli_error($link));
}
}else{
echo die('Could not connect: ' . mysqli_connect_error());
}
?>
Note:- To check php version (either on localhost or on live server) create a file with name phpInfo.php, and just write one line code in that file:-
<?php
phpinfo();
?>
Now run this file and you will get the current php version.
Like this:- https://eval.in/684551
Here it seems that you are using deprecated API of mysql_* .
1) Check your PHP version
<?php phpinfo();exit;//check version ?>
2) avoid the usage of mysql use mysqli or PDO
3) change your db connection string with this :
new Mysqlidb($hostname, $username, $pwd, $dbname);
example with you code
<?php
$link = mysqli_connect('localhost', 'root1', '','vtflix');
if($link){
echo 'connected successfully';
$sql= "INSERT INTO mpaa(C_Name,ContentRating,V_ID) VALUES ('Jon', 4, 3)";
if(mysqli_query($link,$sql)){
$query = "SELECT * FROM mpaa";
$res = mysqli_query($link,$query);
if($res){
while($sqlrow=mysqli_fetch_assoc($query))
{
$row= $sqlrow['C_Name'];
$nrow= $sqlrow['Content Rating'];
$mrow= $sqlrow['V_ID'];
echo "<br>".$row." ".$nrow." ".$mrow."<br>";
}
mysqli_close($link);
}else{
echo die('Query error: ' . mysqli_error($link));
}
}else{
echo die('Query error: ' . mysqli_error($link));
}
}else{
echo die('Could not connect: ' . mysqli_connect_error());
}
?>

PHP-mysql_fetch_array return nothing

I've trying to display values from mysql but it return any empty page. The connection is fine but it does not fetch the data from mysql. I tried all the answers from the similar questions asked. But nothing helped. Can somebody please help me? This is the code
$con= mysql_connect($host, $username, $pwd);
if(!$con)
die("not connected". mysql_errno());
echo(Connected);
mysql_select_db("info",$con);
$query="select * from people";
$result= mysql_query($query,$con) or die(mysql_error());
while($row = mysql_fetch_array($result))
{
echo $row['id']. " - ". $row['people_name'];
echo "<br />";
}
Try to check if your db user,password are correct! I test the code above :
<?php $con=mysqli_connect("localhost","root","","test"); // Check connection
if (mysqli_connect_errno()){
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$result = mysqli_query($con,"SELECT * FROM people");
while($row = mysqli_fetch_array($result)) {
echo $row['id'] . " -- " . $row['people_name']; echo "<br>";
}
?>
and give me the result without error: 10 -- JOHN 11 -- PRADEEP
I just change mysql_connect to mysqli_connect add in $con= mysql_connect($host, $username, $pwd); a dbname. and $con become $con= mysqli_connect($host, $username, $pwd,$dbname); I use mysqli_query instead of mysql_query. Here is a stackQuestion for the mysql vs mysqli in php which can explain you the difference.
Try this
<?php
$con= mysql_connect('hostname', 'username', 'password');
if(!$con)
die("not connected". mysql_errno());
echo("Connected");
mysql_select_db("test",$con);
$query="select * from tabale_name";
$result= mysql_query($query,$con) or die(mysql_error());
while($row = mysql_fetch_array($result))
{
echo $row['id']. " - ". $row['name'];
echo "<br />";
}
?>
check this
<?php
$con=mysqli_connect("hostname","username","password","info");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$result = mysqli_query($con,"SELECT * FROM people");
while($row = mysqli_fetch_array($result))
{
echo $row['id'] . " " . $row['people_name'];
echo "<br>";
}
?>
OR
<?php
$con=mysqli_connect("hostname","username","password");
// Check connection
if ($con)
{
echo "connected to db";
}
else
{
echo "not connected to db";
}
$db_selected = mysql_select_db("info", $con);
if (!$db_selected)
{
die ("Can\'t use info: " . mysql_error());
}
$result = mysqli_query("SELECT * FROM people");
while($row = mysqli_fetch_array($result))
{
echo $row['id'] . " " . $row['people_name'];
echo "<br>";
}
?>

SQL query not functioning correctly, getting no output with a perfectly fine query

code:
<?php
session_start();
if ( isset($_GET['user']) && isset($_GET['pass']) )
{
$sql = "SELECT * FROM `users` WHERE `name` = '" . $_GET['user'] . "' AND `password` = '" . $_GET['pass'] . "';";
echo("query: $sql <br />");
$db = mysqli_connect("localhost", "root", "<password here>", "1596");
if (mysqli_connect_errno($db)) { die("err"); }
$result = mysqli_query($db, $sql);
echo($query);
$row = mysqli_fetch_aray($result);
echo($row);
if ($row['name'] == $_GET['user'])
{
$_SESSION['uid'] = $row['name'];
$_SESSION['level'] = $row['level'];
echo("logged in as " . $_SESSION['uid']);
}
}
else
{
die("Error, not enough parameters");
}
?>
If I run that query on server, it is fine.. there is no connect error, so wondering where I went wrong
$db = mysqli_connect("localhost", "root", "<password here>", "1596");
if (mysqli_connect_errno($db)) { die("err"); }
$result = mysqli_query($db, $sql); // line corrected
$row = mysqli_fetch_array($result); // line corrected

mysql_query not returning data

The table Users contains data but still it shows Records Not Found
<?php
$conn = mysql_connect("localhost", "root", "pass", "Assign1");
$records = mysql_query($conn, "select * from Users");
if(!$records)
{
echo "No Records Found";
exit();
}
while($row = mysql_fetch_array($records))
{
echo $row['name'] . " " . $row['pwd'];
echo "<br />";
}
mysql_close($conn);
?>
You have the parameters to mysql_query reversed. It should be:
$records = mysql_query("select * from Users", $conn);
Your other issue is with the if statement. You're checking if on a query, not on a result set.
Also, I'm sure you probably know but mysql libraries are deprecated and are being removed. You should really learn to use mysqli functions as they will be far more useful to you in the future.
Link to MySQLi documentation - It's really no harder than mysql libraries.
To re-implement in correct libraries:
<?php
$mysqli = new mysqli("localhost", "user", "pass", "database");
$query = $mysqli->query("SELECT * FROM users");
$results = $query->fetch_assoc();
if($results) {
foreach($results as $row) {
echo $row['name'] . " " . $row['pwd'] . "<br/>";
}
} else {
echo "No results found.";
}
?>
Hopefully I didn't just do your whole assignment for you, but it'd probably be worth it to get one more person using mysqli properly.
You have a wrong usage of mysql_query function
use it like this:
<?php
$conn = mysql_connect("localhost", "root", "pass","Assign1");
$result = mysql_query("select * from Users", $conn);
if(!$records)
{
echo "No Records Found";
exit();
}
while($row = mysql_fetch_array($result))
{
echo $row['name'] . " " . $row['pwd'];
echo "<br />";
}
mysql_close($conn);
?>
Lets resolve this issue first.The error it was actually showing is no database selected you have to select the database that needs the code
mysql_select_db("Assign1",$conn);
Hope this code will perfectly sole your issue .Try it once .........
<?php
$conn = mysql_connect("localhost", "root", "pass");
mysql_select_db("Assign1",$conn);
$result = mysql_query("select * from users", $conn);
if(!$result)
{
echo "No Records Found";
exit();
}
while($row = mysql_fetch_array($result))
{
echo $row[0]['name'];
echo "<br />";
}
mysql_close($conn);
?>
here you go
<?php
$conn = mysql_connect("localhost", "root", "pass", "Assign1");
mysql_select_db(' ----your-database-here---', $conn ) ;
$records = mysql_query($conn, "select * from Users");
if(mysql_num_rows($records) > 0 )
{
while($row = mysql_fetch_array($records))
{
echo $row['name'] . " " . $row['pwd'];
echo "<br />";
}
}else
{
echo "No Records Found";
exit();
}
mysql_close($conn);
?>

Data from database is not showing

How can I get data from my database to show. I am not very experienced with PHP or MySQL.
I do not get an error message but no data shows so what am I doing wrong?
PHP
<?php
if(strlen(trim($_POST['search'])) > 0) {
$search = "%" . $_POST["search"] . "%";
$searchterm = "%" . $_POST["searchterm"] . "%";
mysql_connect ("cust-mysql-123-03", "", "");
mysql_select_db ("weezycouk_641290_db1");
if (!empty($_POST["search_string"]))
{
}
$query = "SELECT name,lastname,email FROM contact WHERE name LIKE '%$search%' AND
lastname LIKE '%$searchterm%'";
$result = mysql_query ($query);
echo mysql_error();
if ($result) {
while ($row = mysql_fetch_assoc($result)) {
echo $row["name"];
echo $row["lastname"];
echo $row["email"];
} ?>
<?php echo $row["name"]; ?>
<br>
<?php echo $row["lastname"]; ?>
<br>
<?php echo $row["email"]; ?>
<?php
}
}
?>
It should be like this:
<?php
if(strlen(trim($_POST['search'])) > 0) {
mysql_connect ("cust-mysql-123-03", "", "");
mysql_select_db ("weezycouk_641290_db1");
$query = "SELECT name,lastname,email FROM contact WHERE name LIKE '%" . mysql_real_escape_string($_POST['search']) . "%' AND lastname LIKE '%" . mysql_real_escape_string($_POST['searchstring']) . "%'";
$result = mysql_query ($query);
echo mysql_error();
if ($result) {
while ($row = mysql_fetch_assoc($result)) {
echo $row["name"];
echo $row["lastname"];
echo $row["email"];
} ?>
<?php echo $row["name"]; ?>
<br>
<?php echo $row["lastname"]; ?>
<br>
<?php echo $row["email"]; ?>
<?php
}
}
?>
The mysql_real_escape_string is to prevent mysql injection which is a serious risk.
Make sure the query you are executing returns record(s). You can check this by adding an echo statement which will print the query in your screen. Copy that and run it againist the database.You can use any mysql front end tools(php myadmin,mysqlyog to run the query. If there is any error in the query, you can see that then.
$query = "SELECT name,lastname,email FROM contact WHERE name LIKE '%$search%' AND
lastname LIKE '%$searchterm%'";
//the below line will print the query on the screen
echo $query;
$result = mysql_query ($query);
