我有一个包含很多课程的数据库,例如早餐麦片、早餐吐司、午餐沙拉、午餐主菜等
我用它把他们输入的数据放入一个包含结果的变量中,例如:
breakfast_toast = Wholemeal;Brown;50/50;
and
breakfast_hotdrinks = Tea;Coffee;Milk;
这是我用来收集该信息的脚本:
if(!empty($_POST['toast_selection'])) {
foreach($_POST['toast_selection'] as $toast) {
$toast = trim($toast);
if(!empty($toast)) {
$toastchoices .= "$toast;";
}
}
}
这工作得很好,但我有很多条目要收集,如果他们向数据库添加更多条目,我希望它们自动收集。
我试图想办法,但我就是想不通,这就是我尝试过的:
所有输入的名称与 $course_menuname 相同,例如 Breakfast_cereal[]
$query = "SELECT * FROM course";
$result = mysql_query($query);
while($row = mysql_fetch_array($result))
{
$course_menuname = $row['course_menuname']; #E.G breakfast_cereal, breakfast_toast, lunch_main
$course_item = $row['course_jsname']; #E.G cereal, toast, jacketpotato
$postResults = $_POST[''.$course_menuname .''];
if(!empty($postResults)) {
echo $postResults."<br />";
foreach($postResults as $course_item) {
$course_item = trim($course_item);
if(!empty($course_item)) {
$course_item1 .= "$course_item;";
}
}
}
echo $course_item1."<br />";
}
这就是最终结果应该寻找的
if(!empty($_POST['toast'])) {
foreach($_POST['toast'] as $toast) {
$toast = trim($toast);
if(!empty($toast)) {
$toastchoices .= "$toast;";
}
}
}
if(!empty($_POST['toastextra_selection'])) {
#Gather Toast EXTRAs Choices
foreach($_POST['toastextra_selection'] as $toastextra) {
$toastextra = trim($toastextra);
if(!empty($toastextra)) {
$toastextrachoices .= "$toastextra;";
}
}
}
if(!empty($_POST['toastextra_selection'])) {
#Gather Cold Drinks Choices
foreach($_POST['colddrinks_selection'] as $colddrinks) {
$colddrinks = trim($colddrinks);
if(!empty($colddrinks)) {
$colddrinkschoices .= "$colddrinks;";
}
}
}
if(!empty($_POST['hotdrinks_selection'])) {
#Gather Hot Drinks Choices
foreach($_POST['hotdrinks_selection'] as $hotdrinks) {
$hotdrinks = trim($hotdrinks);
if(!empty($hotdrinks)) {
$hotdrinkschoices .= "$hotdrinks;";
}
}
}
