All N forms must be submitted to the same page for data processing, that is, writing data to the database.
Add. php

Add2.php


Add3.php


Adddate. phpHow should I write this page?

$ Con = mysql_connect ("localhost", "root ","");
If (! $ Con)
{
Die ('could not connect: '. mysql_error ());
}

// Some code
Mysql_select_db ("survey", $ con );


$ SQL = "insert INTO information (t1)
VALUES ('. $ t1 ')";
If (! Mysql_query ($ SQL, $ con ))
{
Die ('Error: '. mysql_error ());
}
Echo "script" alert ('OK! 1 record added') script ";
Mysql_close ($ con );



?>


Thank you for choosing adddate. php.
This is a function problem that I don't quite understand.


------ Solution --------------------
Add different parameters to the action of each form to differentiate processing:

PHP code

  # Add. php # add2.php # add3.php
------ Solution --------------------
If (isset ($ _ POST [t1])
$ SQL = "insert INTO information (t1) VALUES ('{$ _ POST [t1]}')";
If (isset ($ _ POST [t1])
$ SQL = "insert INTO information (t2) VALUES ('{$ _ POST [t2]}')";
If (isset ($ _ POST [t1])
$ SQL = "insert INTO information (t3) VALUES ('{$ _ POST [t3]}')";

No function is required.
