How to save a php file and html form to input data to MySQL database?

[Mbelwa Germano]

Mkuu Heshima Mbele,

Mosi: Nimejaribu kufanya connection ili kuweza kuingiza information kwenye database kupitia html form using php with a file extension .php (as localhost) bila na mafanikio, hivyo naomba msaada katika hili.

Pili: Naomba msaada wa jinsi ya kupopulate information kwenye webpage pale mtu anapotuma comments kupitia the same webpage.

Tatu: Jinsi ya kuritrive information from the database.

Nitashukuru kwa msaada wako.

kupopulate ni afadhali utumie Ajax APIs, soma w3school kwa hilo, na PHP/Mysql connection, chek hii,,,

[h=2]Create a Connection to a MySQL Database[/h]Before you can access data in a database, you must create a connection to the database.
In PHP, this is done with the mysql_connect() function.
[h=3]Syntax[/h]mysql_connect(servername,username,password);


[TABLE="class: reference, width: 1"]
[TR]
[TH]Parameter[/TH]
[TH="width: 80%, bgcolor: #E5EECC, align: left"]Description[/TH]
[/TR]
[TR]
[TD]servername[/TD]
[TD]Optional. Specifies the server to connect to. Default value is "localhost:3306"[/TD]
[/TR]
[TR]
[TD]username[/TD]
[TD]Optional. Specifies the username to log in with. Default value is the name of the user that owns the server process[/TD]
[/TR]
[TR]
[TD]password[/TD]
[TD]Optional. Specifies the password to log in with. Default is ""[/TD]
[/TR]
[/TABLE]
Note: There are more available parameters, but the ones listed above are the most important. Visit our full PHP MySQL Reference for more details.
[h=3]Example[/h]In the following example we store the connection in a variable ($con) for later use in the script. The "die" part will be executed if the connection fails:
<?php
$con = mysql_connect("localhost","peter","abc123");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}

// some code
?>

---

[h=2]Closing a Connection[/h]The connection will be closed automatically when the script ends. To close the connection before, use the mysql_close() function:
<?php
$con = mysql_connect("localhost","peter","abc123");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}

// some code

mysql_close($con);
?>
