Can I mix MySQL APIs in PHP?
(4 answers)
Closed 7 years ago.
I'm trying to run this code in php but does not print anything.
My database is not empty.
<?php
$dbname = "mytest";
$servername = "***";
$username = "mohsen";
$passwords = "****";
// Create connection
$conn = new mysqli($servername, $username, $passwords, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$User=$_POST['username'];
$sql="SELECT * FROM Money WHERE Debtor='$User' OR Creditor='$User' ";
$result = $conn->query($sql);
//
while($field=mysql_fetch_assoc($result))
{
print $field["Debtor"]."|";
print $field["Creditor"]."|";
print $field["Cost"]."|";
print $field["Status"]."|"."\n";
}
$conn->close();
?>
EX:
I have record with this user in my database
User=mohsen

You are mixing object oriented and procedural style query.
<?php
$dbname = "mytest";
$servername = "***";
$username = "mohsen";
$passwords = "****";
// Create connection
$conn = new mysqli($servername, $username, $passwords, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$User=$_POST['username'];
$sql="SELECT * FROM Money WHERE Debtor='$User' OR Creditor='$User' ";
$result = $conn->query($sql);
//
while($field = $result->fetch_object())
{
print $field->Debtor."|";
print $field->Creditor."|";
print $field->Cost."|";
print $field->Status."|"."\n";
}
$conn->close();
?>
<?php
$dbname = "mytest";
$servername = "***";
$username = "mohsen";
$passwords = "****";
// Create connection
$conn = new mysqli($servername, $username, $passwords, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$User=$_POST['username'];
$sql="SELECT * FROM Money WHERE Debtor='$User' OR Creditor='$User' ";
$result = $conn->query($sql);
while($field=$result->fetch_assoc())
{
print $field["Debtor"]."|";
print $field["Creditor"]."|";
print $field["Cost"]."|";
print $field["Status"]."|"."\n";
}
$conn->close();
?>

How to include a PHP variable inside a MySQL statement
(5 answers)
Closed 2 years ago.
I want to select an email from the DB which needs to return the related Account_ID
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "connected accounts details";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT acc_id FROM users
WHERE
email = $user_email";
$result = $conn->query($sql);
echo "$result";
$conn->close();
This code returns nothing, just blank.
While using the same connection/db data is being inserted in db successfully.
Try this code
// Php Sql Select From DB....
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "connected accounts details";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT `acc_id` FROM `users` WHERE `email` = ?";
$result->$conn->prepare($sql);
$result->bind_param('s',$user_email);
$result->execute();
$data = $result->get_result();
// Fetch all
$data->fetch_all(MYSQLI_ASSOC);
print_r($data);
$mysqli -> close();
// #link http://php.net/manual/en/mysqli-result.fetch-all.php
$sql = "SELECT acc_id FROM users
WHERE
email LIKE '%$user_email%' ";
$result = mysqli_query($conn, $sql);
$row = $result->fetch_assoc();
$id = $row['acc_id'];
echo "$id";
$conn->close();
Got the wanted Record, trying this way.
Thanks everyone answering on this post.
When I run this code it shows parse error. Can anyone help me with this?
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "form";
// Create connection
$conn = new mysqli($servername, $username,$password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " .$conn->connect_error);
}
SELECT * FROM my_db;
$conn->close();
You should use php tags and remove those ">" also you should use mysqli_query to query the data from mysql
<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "form";
// Create connection
$conn = new mysqli($servername, $username,$password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " .$conn->connect_error);
}
$query = mysqli_query($conn,"SELECT * FROM my_db");
$conn->close();
?>
My table has 2 fields a primary with auto increment and then entry_id
why does the below not insert in the table:
<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "ecolog";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$entry_id = 5;
$sql = "INSERT INTO orders (entry_id) VALUE ('$entry_id')";
$conn->close();
?>
but when adding a error check it does?
<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "ecolog";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$entry_id = 5;
$sql = "INSERT INTO orders (entry_id) VALUE ('$entry_id')";
if ($conn->query($sql) === TRUE) {
echo "";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();
?>
cant get my head around why this would be happening.
I want to fetch time column from mysql database and to compare with current time.
It should execute only if it matches with the current time.
Please tell me a MySql query or php code to do this.
I am new to php.
Try This:
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$today = date("h:i a")
$sql = "SELECT * FROM Table_name WHERE SUBSTRING_INDEX(time, ' ', 2) = '".$today."'";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// execute you code
} else {
}
$conn->close();
?>
Try this: Updated Code
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$today = date("h:i a")
$sql = "SELECT * FROM Table_name WHERE time = $today";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// execute you code
} else {
}
$conn->close();
?>

<?php
$servername = "localhost";
$username = "user";
$password = "pass";
$dbname = "test";
$tablename = "mapcoords";
$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error)
{
echo "Failure";
die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
$sql = "SELECT (lat, lng) FROM mapcoords";
$result = $conn->query($sql);
while($row = $result->fetch_assoc())
{
echo "ok";
}
$conn->close();
?>
Here is the code. So like I said, it can connect successfully, but the code won't successfully query. What's weird is that if I copy and paste the same code, which seems to be EXACTLY the same, it works. It makes no sense. I can't find a single difference between their code and my code besides the way they space things and the way I space things. Here is their code:
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT (lat, lng) FROM mapcoords";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo $row["lat"]. " " . $row["lng"] . "<br>";
}
} else {
echo "0 results";
}
$conn->close();
?>
The problem is that this query:
SELECT (lat, lng) FROM mapcoords
returns the folloowing error:
[21000][1241] Operand should contain 1 column(s)
You have to change the query to
SELECT lat, lng FROM mapcoords
