Question

Can somebody tell me the PHP code and MySQL query so I can post radio buttons data into MySQL fields? I’ve a MySQL table called “Attendance” which has four fields:

• present
• absent
• leave
• holiday

My HTML form contain four radio buttons as well like

<input type="radio" name="present" value="1" />
<input type="radio" name="absent" value="2" />
<input type="radio" name="leave" value="3" />
<input type="radio" name="holiday" value="4" />

What I want is that if someone select absent radio button, then 2 should go to absent field in Attendance Table and other 3 fields will be empty in table; if someone select present then 1 should go to present field in Attendance and other 3 fields of absent leave holiday will be empty.

Also names are differents of 4 radio buttons, so there is problem that i can select all 4 radio buttons. How can I make them select one out of 4? I know if names are same then I have choice to select 1 but here is different issue, 4 different fields.

Give all elements of the radio group the same name. This will do it for the HTML part. In PHP you do a simple switch depending on the REQUEST value:

<?php
    $defaultInsertData = array(0,0,0,0);
    $currentValue = intval($_REQUEST['FIELDNAME']);
    switch($currentValue) {
        case 1:
            $defaultInsertData[0] = 1;
            break;
        case 2:
            $defaultInsertData[1] = 2;
            break;
        case 3:
            $defaultInsertData[2] = 3;
            break;
        case 4:
            $defaultInsertData[3] = 4;
            break;
    }
    // and here you have your array with the four elements.... 
    var_dump($currentValue);
?>
