Re-populating a form if errors

#1 July 17th, 2005, 02:29 AM

Hello,

I am learning php. I have created a simple Web page with a form.
After receing the POST request, I do some error checking. In case of
errors, I would like to re-post the page, but with the current values
for each field.

I have organized my files like this:
1) Webpage with the form (all in html, form action points to a php
file)
2) php file that receives the request.

Is there a simple way to accomplish this?

it is simpler to put everything in one php file and checking
whether the $_POST array is not empty.

you can keep your values with a construction like this:

<input name="author" <?php if (isset($_POST['author']))
{echo " value=$_POST['author']";}?>>

when you reload the page in the input there is the option value so you
would do:

<input ..... value=<? echo $test; ?> />

hope this is right :p

Do it all in one file, for example parse_my_form.php:

<?php

$str_name = !empty($_POST['name']) ? $_POST['name'] : "";
$str_age = !empty($_POST['age']) ? $_POST['age'] : "";
$str_error = "";

if($str_name == "" or $str_age == "")
$str_error = "<p>Error parsing form</p>";
else
header("Location: http://mywebsite.com/form_submission_ok.php");
?>

<html>
<head>
<title>Fill in the boxes!</title>
</head>

<body>

<?php echo $str_error ?>

<form name="form1" action="parse_my_form.php" method="post">

<input name="name" type="text">
<input name="age" type="text">
<input type="submit">

</form>

</body>
</html>

The super lazy way to do it

header("HTTP/1.0 204 No Content");
exit();

Ooops... change these lines:

<input name="name" type="text">
<input name="age" type="text">

To this:

<input name="name" type="text" value="<?php echo $str_name ?>">
<input name="age" type="text" value="<?php echo $str_age ?>">
