PHP Session - Checkbox,Radio and List/Menu

显示全部楼层 · 发表于 22-8-2007 02:31 AM

请问我要如何才能像Name textfield那样，按"Change"钮时checkbox, radio和List/menu保留原先用户的选项呢？谢谢！

<?php session_start();
$_SESSION['Name'] = $_POST['Name'];
?>
<html>
<head>
<title>Testing</title>
</head>
<body>
<?php
if ($_POST['submit'] == 'submit')
{
$Name=$_POST['Name'];
if($_POST["hobby1"])
{ foreach($_POST['hobby1'] as $value)
{
$hobby2=join (', ', $_POST['hobby1']);
}
}
echo
("
Name: $Name<br>
Hobby: $hobby2<br>
");
echo
("<form name='frmtest' method = 'post' action='test.php'>
<input type = 'hidden' name = 'Name' value = '$Name'>
<br>
<input type = 'submit' name = 'change' value = 'Change' onclick='buy4D.php'>
</form>");
exit;
}
?>
<form name="frmtest" method="post" action="test.php">
  <p>
<strong>Name:</strong>
<input type="text" name="Name" value="<?php echo $_SESSION['Name'] ?>">
<br>
<br>
<strong>Hobby:</strong><br>
  <input name="hobby1[]" type="checkbox" value="Gaming">
  Gaming
  <input name="hobby1[]" type="checkbox" value="Cooking" id="hobby1">
  Cooking
  <input name="hobby1[]" type="checkbox" value="Swimming">
  Swimming<br>
  <strong><br>
  Sex:</strong><br>
  <input type="radio" name="sex" id="radio" value="female">
  Female
  <input type="radio" name="sex" id="radio2" value="male">
  Male <br>
  <br>
<strong>Career:</strong>
<select name="career" id="career">
   <option value="Lawyer">Lawyer</option>
   <option value="Doctor">Doctor</option>
   <option value="Engineer">Engineer</option>
</select>
<br>
<br>
<input type="submit" name="submit" value="submit">
</form>
</body>
</html>

可以那样写：

<input name="hobby1[]" type="checkbox" value="Gaming" <?php echo (($_SESSION['hobby1'] == "Gaming")?"SELECTED":""); ?>>
  Gaming
  <input name="hobby1[]" type="checkbox" value="Cooking" id="hobby1" <?php echo (($_SESSION['hobby1'] == "Cooking")?"SELECTED":""); ?>>
  Cooking
  <input name="hobby1[]" type="checkbox" value="Swimming" <?php echo (($_SESSION['hobby1'] == "Swimming")?"SELECTED":""); ?>>
  Swimming

menu 也一样.
