php error creating mysql table

Question

I have the following php file to create a database and table:

<?php
$slName = $_POST['slName'];
$con=mysqli_connect('localhost', 'setlist', 'music');
// Check connection
if (mysqli_connect_errno())
  {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
  }

// Create database
$sql="CREATE DATABASE $slName";
if (mysqli_query($con,$sql))
  {
  echo "Database " . $slName . " created successfully";
  }
else
  {
  echo "Error creating database: " . mysqli_error();
  }


  // Create table
$tbl="CREATE TABLE main (name TEXT,orderno INT,Age TEXT)";

// Execute query
if (mysqli_query($con,$tbl))
  {
  echo "Table persons created successfully";
  }
else
  {
  echo "Error creating table: " . mysqli_error();
  }
?>

When it runs I it returns this:

Database created successfully Error creating table:

I executed this via the command prompt with success:

CREATE TABLE main (name TEXT,orderno INT,Age TEXT);

What am I doing wrong?

Thanks so much!

Answer 1

您必须选择要在其中创建表的数据库

  mysqli_select_db($slName);

Answer 2

创建数据库后添加mysqli_select_db($slName);
