如何使用php保存数据库中的多个单选按钮而不保存按钮值

Question

how to save multiple radio button in database using php without save button value.

my code :

$user_id = $_POST['user_id'];
foreach ( $_POST as $key => $val ) {   
    if ($key <> 'user_id') {
        $bidder_interst_insert="INSERT INTO bidder_interest_list(id, bidder_id, bidder_interest_name) VALUES ('','$user_id','$val')";
        $bidder_interst_insert_result = mysql_query($bidder_interst_insert);
        if (mysql_affected_rows() > 0) {
            $interest_list_success = "Thank you Successfull insert your interst list.";
            $_SESSION['interest_list_success_msg'] = $interest_list_success;
        } else {
            $insert_error = "interst list Insert Error.";
            $_SESSION['insert_error_msg'] = $insert_error;
            header("location:interest_list.php");
        }
    }
}

This code work but database extra save in save button value how to solved this problem??

Answer 1

foreach ( $_POST as $key => $val ){

You are directly looping the $_POST, so the SAVE button value is also saving in the database. Take the values individually instead of looping the whole $_POST, then the SAVE button value won't be saved in the database.

And moreover you are using mysql functions which are deprecated, use mysqli or PDO.

EDIT:: Just take it the same way as u took user_id ==> $variablename = $_POST['fieldname'];

EDIT::: Let me suppose i have a form like this

<form name="form1" id="form1" method="post" action="">
        <input type="checkbox" name="products[]" value="A" checked="checked" />A <br />
        <input type="checkbox" name="products[]" value="B" checked="checked" />B <br />
        <input type="checkbox" name="products[]" value="C" checked="checked" />C <br />
        <input type="checkbox" name="products[]" value="D" checked="checked" />D <br />
        <input type="checkbox" name="products[]" value="E" checked="checked" />E <br />
        <input type="checkbox" name="products[]" value="F" checked="checked" />F <br />

        <input type="submit" name="save" id="save" value="Save" />
    </form>

then i can do it like:

<?php
    if(isset($_POST['save']))
    {
        $products = $_POST['products'];
        foreach($products as $key => $value)
        {
            $qry = mysql_query("INSERT INTO tbl(product) VALUES('$value')");
        }
    }
?>
