How to get multiple parameters with same name from a URL in PHP and insert all records into table

问题

I'm using MySQL query to insert multiple records into table. In my url i get all records that i have entered but in database it only updates my last record. I am using here onclick function to add new table rows. Any help. Here is my code

if (isset($_GET['submit']))
{
    require_once("shine_class.php");
    $s = new shine;
    $s->connection();
    $date1 = date_default_timezone_set('Asia/Kolkata');

    $date1= time() ;
    $newdate1 = date("d-m-Y", $date1);


    for ($i=0; $i < count($_GET['finished_product_name']); $i++ )
    {
        $product =$_GET['finished_product_name'];
        $material = $_GET['material_name'];
        $quantity = $_GET['product_quantity'];

        // mysql_query("INSERT INTO material_used (product_name, material_name, product_quantity, date) VALUES ('$a', '$b', '$c','$newdate1')") or die(mysql_error());
        $insert ="insert into material_used set `product_name` = '".$product."', `material_name` = '".$material."', `product_quantity` = '".$quantity."',`date` = '".$newdate1."' ";                   
        $select = mysql_query($insert) or die(mysql_error());
    }
}

回答1:

You try to assign a value with same name.so your last value replace with the existing value.

for example :your URL look like,

http://www.example.com/index.php?finished_product_name=abc&material_name=xxx&finished_product_name=pqr&material_name=yyy

so your $_GET['finished_product_name'] has value is pqr not abc.

If you can change the field name with include [], then PHP will create an array containing all of the matching values:

http://www.example.com/index.php?id[]=123&version[]=3&id[]=234&version[]=4

your URL example like,

http://www.example.com/index.php?finished_product_name[]=abc&material_name[]=xxx&finished_product_name[]=pqr&material_name[]=yyy

your for loop is :

for ($i=0; $i < count($_POST['finished_product_name']); $i++ )
{
    $product =$_POST['finished_product_name'][$i];
    $material = $_POST['material_name'][$i];
    $quantity = $_POST'product_quantity'][$i]; 
}

回答2:

$insert ="insert into material_used(product_name,material_name,product_quantity,date) VALUES( '$product',  '$material','.$quantiy','$newdate1')

use following function to insert data in DB

$data['col1']='value1';
$data['col2']='value2';
.
.
$data['coln']='valuen';

insert('table_name',$data);

    function Insert( $table, $condition )
{
    $sql = "INSERT INTO `$table` SET ";
    $content = null;
    foreach ( $condition as $k => $v )
    {
        $v_str = null;
        if ( is_numeric($v) )
            $v_str = "'{$v}'";
        else if ( is_null($v) )
            $v_str = 'NULL';
        else
            $v_str = "'" . mysql_real_escape_string($v) . "'";

        $content .= "`$k`=$v_str,";
    }
    $content = trim($content, ',');
    $sql .= $content;
    return $result = mysql_query($sql);
}
