Mysql Insert Query In Php
PHP MySQL Insert Into :
The INSERT INTO statement is used to insert new records into a database table.
Insert Data Into a Database Table :
The INSERT INTO statement is used to add new records to a database table.
Syntax
//Syntax
INSERT INTO table_name
VALUES (value1, value2,....)
You can also specify the columns where you want to insert the data:
Syntax
INSERT INTO table_name (column1, column2,...)
VALUES (value1, value2,....)
Note: SQL statements are not case sensitive. INSERT INTO is the same as insert into.
To get PHP to execute the statements above we must use the mysql_query() function. This function is used to send a query or command to a MySQL connection.
Example :In the previous chapter we created a table named "Person", with three columns; "Firstname", "Lastname" and "Age". We will use the same table in this example. The following example adds two new records to the "Person" table:
CODE/PROGRAM/EXAMPLE
<?php
$con = mysql_connect("localhost","peter","abc123");
if (!$con)
{
die("Could not connect: "" . mysql_error());
}
mysql_select_db("my_db", $con);
mysql_query("INSERT INTO person (FirstName, LastName, Age)
VALUES ("Peter", "Griffin", "35")");
mysql_query("INSERT INTO person (FirstName, LastName, Age)
VALUES ("Glenn", "Quagmire", "33")");
mysql_close($con);
?>
Insert Data From a Form Into a Database :
Now we will create an HTML form that can be used to add new records to the "Person" table.
CODE/PROGRAM/EXAMPLE
//Here is the HTML form:</br>
<html>
<body>
<form action="insert.php" method="post">
Firstname: <input type="text" name="firstname" />
Lastname: <input type="text" name="lastname" />
Age: <input type="text" name="age" />
<input type="submit" />
</form>
</body>
</html>
When a user clicks the submit button in the HTML form in the example above, the form data is sent to "insert.php". The "insert.php" file connects to a database, and retrieves the values from the form with the PHP $_POST variables.
Then, the mysql_query() function executes the INSERT INTO statement, and a new record will be added to the database table.
Below is the code in the "insert.php" page:
CODE/PROGRAM/EXAMPLE
<?php
$con = mysql_connect("localhost","peter","abc123");
if (!$con)
{
die("Could not connect: " . mysql_error());
}
mysql_select_db("my_db", $con);
$sql="INSERT INTO person (FirstName, LastName, Age)
VALUES
("$_POST[firstname]","$_POST[lastname]","$_POST[age]")";
if (!mysql_query($sql,$con))
{
die("Error: " . mysql_error());
}
echo "1 record added";
mysql_close($con)
?>
