Self Submit form ?

mrbluevn

Hi everybody,

I wrote an example of using self submit form like this, however it doesn't work:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"
"http://www.w3.org/TR/REC-html40/loose.dtd">
<html>
<head>
<title>Array</title>
<meta http-equiv="Content-Type"
content="text/html; charset=iso-8859-1">
</head>
<body>
<?php
if ($_SERVER['REQUEST_METHOD'] != 'POST'){$me = $_SERVER['PHP_SELF'];?>
<?php $city =array(0 => "Ho Chi Minh", 1 => "Ha Noi", 2 => "Da Nang");
$count = count($city); ?>
<form method="POST" target="<?php echo $me;?>" enctype="text/plain"><select name= "city" size="1" height="1">
<?php for ($i = 0; $i < $count; $i++) {
echo "<option value=\"".$city[$i]."\">".$city[$i]."</option>";
}?>
</select>
<input type="text" name="name" />
<input type="submit" name="Submit" value="Send"></form>
<?php } else {
$new = stripslashes($_POST['city']);
$name = stripslashes($_POST['name']);
echo $new." is ".$name." s city";
}
?>
</body>
</html>

Is there any advices ?

Thank u very much !

I usually do something like this to make the code more clear:

<?php

// Handle form submission
if( $_POST['action'] == "submit" ) {

// Process form submission
...
...
// Success message/redirect here
...

}

?>


<form action="" method="post">

// Input elements here
...
...
<input type="hidden" name="action" value="submit" />
<input type="submit" value="Submit" />

</form>

You don't necessarily have to use a hidden field -- you could add a name attribute to the submit button and check that value instead. Personally, I think it makes the code easier to understand, as complex self-submissions can get confusing rather quickly.

As for your code specifically, try changing

if ($_SERVER['REQUEST_METHOD'] != 'POST'){

if (!empty($_POST['Submit']) ){

Hi Aksival, thx for your reply. I tried your suggestion, but unfortunately, it doesn't work either. I tried another way like belo"

<?php GLOBAL $city;
$city =array(0 => "Ho Chi Minh", 1 => "Ha Noi", 2 => "Da Nang");$count = count($city); ?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"
"http://www.w3.org/TR/REC-html40/loose.dtd">
<html>
<head>
<title>Contact Form</title>
<meta http-equiv="Content-Type"
content="text/html; charset=iso-8859-1">
</head>
<body>
<?php
if ($_SERVER['REQUEST_METHOD'] != 'POST'){ $me = $_SERVER['PHP_SELF'];
?>
<form name="form" method="post" action="<?php echo $me;?>"><select name= "City" size="1" height="1">
<?php for ($i = 0; $i < $count; $i++) {
echo "<option value=\"".$city[$i]."\">".$city[$i]."</option>";
}?>
</select>
<input type="text" name="Name" />
<input type="submit" name="Submit" value="Send"></form>
</form>
<?php } else {
error_reporting(0);
$new = stripslashes($_POST['City']);
$name = stripslashes($_POST['Name']);
echo $new." is ".$name." 's city";
}
?>
</body>

I tested and it worked already
