使用PHP从下拉列表中显示选定值的记录

Question

I have populated a drop down with database values. Now I want to display a record from the database for a selected value in the drop down.

For example, the drop down contains:

1
2
3
4

If the selected value is 1 , it will show the record for id 1 below the drop down.

id | name | address | date
1  | jay  | India   | 23/2/1970

How can I do this?

Answer 1

Name your select tag as id:

<form action="" method="POST">
    <select name=id>
        <option value=1></option>
        <option value=2></option>
        <option value=3></option>
    </select>
</form>

<?php
    $select = $_POST['id'];
    $record = "select * from table_name where id=$select";
    $record1 = mysql_query($record);
?>`

Answer 2

Here is your SQL code:

select * from tb_first
  where id =1;
