Мой код java-скрипта не работает, когда я выбираю meal_name в опции drown down, он не заполняет поле ввода meal_price.
у меня есть код java-скрипта, который, как предполагается, заполняет поле ввода meal_price, когда я выбираю meal_name в поле опций.в чем может быть проблема с моим кодом?
Ниже приведен мой код.
Что я уже пробовал:
<?php
//$uid = $_SESSION['uid'];
if(isset($_SESSION['uid'])){
echo $_SESSION['uid'];
}
include("../dbConfig.php");
include "user_navigation.php";
include "../header.php";
include "../footer.php";
$query = "Select Max(meal_id) From meal_table";
$returnD = mysql_query($query);
$result = mysql_fetch_assoc($returnD);
$maxRows = $result['Max(meal_id)'];
if(empty($maxRows)){
$lastRow = $maxRows = 101;
}else{
$lastRow = $maxRows + 1 ;
}
?>
<?php
//REQUEST FOR Meals...
$query = "Select Max(meal_id) From meal_table";
$returnD = mysql_query($query);
$result = mysql_fetch_assoc($returnD);
$maxRows = $result['Max(meal_id)'];
if(empty($maxRows)){
$lastRow = $maxRows = 101;
}else{
$lastRow = $maxRows + 1 ;
}
if (isset($_REQUEST['mealRequestBtn'])) {
$requestid = $_REQUEST['requestid'];
$meal_id = $_REQUEST['meal_id'];
