Hello guys i have problem with inserting data in mysql database.I accepted a project that my friend worked.
I make simple php test file and try to insert in table _content_city. query is successfully executed bu no records in database column when i check in phpmyadmin.
$handler = mysql_connect($server, $user, $pass);
$database = mysql_select_db($dbname);
if(!$handler) :
die("Faild connect to MySQL :" . mysql_error());
endif;
if(!$database) :
die("DB with name ". $dbname . " no exists " . mysql_error());
endif;
mysql_query("INSERT INTO _content_grad (wishlist) VALUES('BlaBlaBla') ") or die(mysql_error());
printf ("Inserterd records: %d\n", mysql_affected_rows());
When i execute this code in browser i have message Inserterd records: 1
But when i check in phpmyadmin that data no exist in column. I dont know whay.
You guys can see image and u will see column wishlist is empty.

I check foreign_keys and remove all foreign_keys and again dont work.
Like test i make new database with name new_test_base and make table albums and column title and like test i execute my php code and all data is successfully inserted when i check in phpmyadmin. So problem is only in that database, i have full access and privilegies i use root (ALL)
Any solution to fix this. Thanks
The MySQL_* range of functions have been depreciated and are no longer reccomened for use. Use the MySQLi_* range of functions instead.
In your code, put the following line echo mysql_errno($handler) and it should display the latest error retuned by MySQL, a MySQLi version of this function is also available.

So I'm starting to learn how to use PHP to access MYSQL databases and after successfully connecting to the database. I want to select data from it. However I get the issue that the table doesn't exist. Yet, it exists when I check it in my phpmyadmin. I've checked spelling, capitalization, etc.. and nothing works. I've tried it with multiple databases and I get the same error. So I'm really confused as to whats going on because from the looks of it, there is NOTHING wrong with the code. I've tried running the SQL query in phpmyadmin just to verify that the query works.. and it does. I just get the error "Table 'test.blog_table' doesn't exist" with the code below
<?php
$host = "localhost";
$user = "root";
$password = "";
$database_in_use = "test";
$conn = new mysqli($host, $user, $password, $database_in_use);
if ($conn->connect_errno) {
echo "Failed to connect to MySQL: (" . $conn->connect_errno . ") " . $conn->connect_error;
}
echo $conn->host_info . "<br>";
$sql = "SELECT * FROM blog_table";
$result = $conn->query($sql);
$result = $conn->query($sql) or die($conn->error);
$conn->close();
?>
So I'm just completely lost and have no idea whats going on with it.
Solved! I connected to the wrong database, which is why the tables were there, but weren't showing up. Since I was connecting to a different database and the one I created tables in didn't have the default port.
Probably you are missing the mysqli and the mysqlnd PHP extensions.
Also, I recommend you to use \PDO object to fetch queries to your DB instead of the mysqli driver, if you do it, you will be free to change in the future to a PostgreSQL DB for example anytime just changing the DSN in the constructor (you need for that the PDO and the pdo_whatever_db_driver (e-g.: pdo_mysql) extensions.
At first I'm sorry for posting duplicate question I always try to find answers and never to ask. But nothing solved my problem. I have a MySql DB with table named data. I cannot change the table name. When I execute SELECT * FROM `data` or SELECT * FROM data in phpMyAdmin, the query works correctly but when I execute it in PHP script the query() returns false
<?php
$conn = new mysqli('localhost', 'username', 'pswd', 'dbname');
if ($conn->connect_error) {
die('connection error');
}
$result = $conn->query("SELECT * FROM `data`");
var_dump($result);
echo "-".$conn->error."-";
I have looked at these questions:
Mysql query works in phpmyadmin but not in php (due to date)
Mysql query works in Phpmyadmin but not works in PHP
MySQL query working in phpmyadmin but not in php
and some others...
$result ="SELECT * FROM `data`";
$row=mysqli_query($conn,$result);
while($row_result=$row->fetch_assoc())
print_r($row_result);
With your replies I've got some idea what to try next.I've created copy of the table on my own server and tried changing data types. One of data types in original table is set as JSON, when i changed it to TEXT it started to work.
I am using the external authentication system. Therefore, there are a lot of user data, which is not available in Phorum.
I am using the last post module, although I want to get the information from the last post user, from my own user table (I have some data, like avatar, birth info etc). I want to show in my Phorum. How can I achieve this?
I've tried to simply connect via a: mysql_query(); but then I just get No database selected error.
I've searched for hours - I cannot find any documentation regarding getting custom data from your own user table.
I would recommend using mysqli, as mysql is deprecated. First make sure that your connection is correct. No database selected means you probably do not have your connection included at the top.
$con = mysqli_connect("localhost","username","password","database");
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: ".mysqli_connect_error());
}
Make sure that your sql statement looks like so (Notice the $con in the mysqli_query()):
$sql = "select * from TableName";
if ($que = mysqli_query($con, $sql)) {
// Query has ran
}
I've made this a lot of times but now I can't :(
The insert allways return false but if I execute the same SQL script (taked from the output) it inserts in the database without any problem. I'm connected to the database because some values are fetched from another table.
This is my code:
$query = "INSERT INTO normotensiones(fecha,macropera,pozo,equipo_pmx,equipo_compania,paciente,sexo,edad,id_compania,otra_compania,puesto,ta,tum,ove,coordinador)
VALUES('$fecha','$macropera','$pozo','$equipo_pmx','$equipo_compania','$paciente','$sexo',$edad,$id_compania,'$otra_compania','$puesto','$ta','$tum','$ove','$coordinador')";
if (mysql_query($query,$connection)){
//OK
} else {
$errno = mysql_errno();
$error = mysql_error();
mysql_close($connection);
die("<br />$errno - $error<br /><br />$query");
exit;
}
The output is:
0 -
INSERT INTO normotensiones(fecha,macropera,pozo,equipo_pmx, equipo_compania,paciente,sexo,edad,id_compania, otra_compania,puesto,ta,tum,ove,coordinador)
VALUES('20111001','P. ALEMAN 1739','P. ALEMAN 1715','726', 'WDI 838','SERGIO AYALA','M',33,21, '','','110/70','ROBERTO ELIEL CAMARILLO','VICTOR HUGO RAMIREZ','LIC. PABLO GARCES')
Looks like there are no error, but allways execute the code in the else part of the if instruction. Any idea? Thanks in advance.
I think the issue might be you are missing the mysql_select_db line after the connection.
After the connection with the database is established you need to select a DB. Please make sure you have selected the Database that your desired table resides in.
And you can even use the following snippets to get some useful informated through mysql_errors.
$connection = mysql_connect('localhost', 'root', 'password');
if (!$connection) {
die('<br>Could not connect: ' . mysql_error());
}
if (!mysql_select_db('db_name')) {
die('Could not select database: ' . mysql_error());
}
And try you insert query after these lines of code. All the best.
I agree with the others concerning the column types. INT is one of the only data types that do not require single quotes.
There are two blank strings. There is a possibility that the variables are not defined, and therefore giving you a PHP exception (not even in the MySql yet) but that requires stricter-than-normal exception settings. I would personally look into the $connection variable. Before the SQL query statement, put this and send us the cleaned results:
echo '<pre>'.var_dump($connection, true).'</pre>';
Additionally, on your mysql_connect function call, put
OR die('No connection')
afterwords. Do the same thing with the mysql_select_db function, changing it to 'No DB Select' obviously.
Ultimately, we will need more information. But changing to mysqli is very desirable.
Oh! And make sure the permissions for the user you are connecting as are not changed. Sometimes I find people who connect to PhpMyAdmin using one user account but a different account in their PHP code. This is problematic, and will lead to problems eventually, as you forget the different accounts, at times.
I'm trying to delete a row from a table in MySQL using the PHP code below. The return value from mysql_affected_rows() is 1. There are no errors. However, the row still exits in MySQL. Not sure what I'm doing wrong. Any thoughts?
$db = array('host'=>'127.0.0.1',
'user'=>'root',
'pass'=>'',
'name'=>'testdb');
// CONNECT TO THE MYSQL SERVER
$connection = mysql_connect($db['host'], $db['user'], $db['pass']);
if(!$connection){
// HANDLE ERROR HERE
die('Unable to connect to MySql server : '.mysql_error($connection));
}
// SELECT THE DATABASE SCHEMA
if(!mysql_select_db($db['name'],$connection)){
// HANDLE ERRORS HERE
die('Unable to connect to database : '.mysql_error($connection));
}
$result = mysql_query("delete from photos where id=".$photo_id, $connection);
echo mysql_affected_rows($connection);
UPDATE
I added the following code to the end and that solved the issue -
mysql_query("commit", $connection);
Thanks for the comments!
Applied to innodb tables as in your case.
mysql_query("BEGIN", $connection);
// delete code
mysql_query("COMMIT", $connection);
What I typically do in this cases is to enable the general_log (set global general_log_file=general.log; and set global general_log=1;) and look what arrives in there.
Then it often becomes already obvious what is the problem.
If it is not clear yet what is going on you can run these queries on the mysql console...
