about how to get the ID of the value that the dropdown box loops out of
The data for my drop-down box is the loop-through code from the database as follows
while ($row _all = mysql_fetch_array ($query _all)) {?>
I put it in the form, and I want to get the ID of the selected content after I submit it

What should I get on the next page, maybe my dropdown box id attribute did not add, I do not know how to add, please expert advice, thank you

How does the caption get the ID of the value that the dropdown box loops out of? So you're going to have to assign an ID to the loop?

$i = 0;
while ($row _all = mysql_fetch_array ($query _all)) {?>


$i + +;



Make a hidden JS trigger on this page. Specific code you have to look for, I JS also unfamiliar, detailed forget, can not mislead you
function Addid () {//Get selected id//write a hidden value
}

When you submit the form, it will pass selectid the past ... But what's the point of passing this ID?

while ($row _all = mysql_fetch_array ($query _all)) {?>

Receive page $_post[' name '].
