在一个页面中有两个表单并设置会话

Question

i have two file and two forms:

file 1:

<form name="name1" action="form2.php" method="post">
     <input <? $_session['define'] = 'value1' ?> type="submit" ...>
</form>
<form name="name2" action="form2.php" method="post">
     <input <? $_session['define'] = 'value2' ?> type="submit" ...>
</form>

As you see i have two forms and two different submit buttons but when i press each of them, the second value (the last) set to the $_session['define'] and in the second form i always have 'value2'.

You must post the data to PHP:

<form name="name1" action="form2.php" method="post">
     <input name='v1' value='1' type="submit" />
</form>
<form name="name2" action="form2.php" method="post">
     <input name='v2' value='2' type="submit" />
</form>

In form2.php:

<?php
session_start();
$_SESSION['value1'] = isset($_POST['v1'])?$_POST['v1']:0;
$_SESSION['value2'] = isset($_POST['v2'])?$_POST['v2']:0;
?>

Personally, I would make it one form and use JQuery/AJAX to POST the values.

<form id="selectForm" name="name1" action="form2.php" method="post">
     <input id="v1" name='v1' value='1' type="submit" />
     <input id="v2" name='v2' value='2' type="submit" />
</form>
<script>
// Requires JQuery
$("#selectForm input[id^='v']").click(function(e){
    e.preventDefault();
    $.post(form2.php, { $(this).attr("name"): $(this).attr("value") }, function(){ alert("Selection Saved.) });
});
</script>
