I am working on a project and would like to give the user per-determined values when updating a record.
Here is my code so far.
<?php
// if there are any errors, display them
if ($error != '')
{
echo '<div style="padding:4px; border:1px solid red; color:red;">'.$error.'</div>';
}
?>
<form action="" method="post">
<input type="hidden" name="id" value="<?php echo $id; ?>"/>
<div>
<p><strong>ID:</strong> <?php echo $id; ?></p>
<strong>School Name:</strong> <input type="text" name="Name" value="<?php echo $Name; ?>"/><br/><br>
<strong>Status:</strong> <input type="text" name="Status" value="<?php echo $Status; ?>"/><br/><br>
<strong>Comments:</strong> <input type="text" name="Comments" value="<?php echo $Comments; ?>"/><br/><br>
<strong>Type:</strong> <input type="text" name="Type" value="<?php echo $Type; ?>"/><br/><br>
<input type="submit" name="submit" value="Submit">
</div>
</form>
</body>
</html>
<?php
}
// connect to the database
include('connect-db.php');
// check if the form has been submitted. If it has, process the form and save it to the database
if (isset($_POST['submit']))
{
// confirm that the 'id' value is a valid integer before getting the form data
if (is_numeric($_POST['id']))
{
// get form data, making sure it is valid
$id = $_POST['id'];
$Name = mysql_real_escape_string(htmlspecialchars($_POST['Name']));
$Status = mysql_real_escape_string(htmlspecialchars($_POST['Status']));
$Comments = mysql_real_escape_string(htmlspecialchars($_POST['Comments']));
$Type = mysql_real_escape_string(htmlspecialchars($_POST['Type']));
// check that firstname/lastname fields are both filled in
if ($Name == '' || $Type == '')
{
// generate error message
$error = 'ERROR: Please fill in all required fields!';
//error, display form
renderForm($id, $Name, $Status, $Comments, $Type, $error);
}
else
{
// save the data to the database
mysql_query("UPDATE Schools SET Name='$Name', Status='$Status', Comments='$Comments', Type='$Type' WHERE id='$id'")
or die(mysql_error());
// once saved, redirect back to the view page
header("Location: view.php");
}
}
else
{
// if the 'id' isn't valid, display an error
echo 'Error!';
}
}
else
// if the form hasn't been submitted, get the data from the db and display the form
{
// get the 'id' value from the URL (if it exists), making sure that it is valid (checing that it is numeric/larger than 0)
if (isset($_GET['id']) && is_numeric($_GET['id']) && $_GET['id'] > 0)
{
// query db
$id = $_GET['id'];
$result = mysql_query("SELECT * FROM Schools WHERE id=$id")
or die(mysql_error());
$row = mysql_fetch_array($result);
// check that the 'id' matches up with a row in the databse
if($row)
{
// get data from db
$Name = $row['Name'];
$Status = $row['Status'];
$Comments = $row['Comments'];
$Type = $row['Type'];
// show form
renderForm($id, $Name, $Status, $Comments, $Type, '');
}
else
// if no match, display result
{
echo "No results!";
}
}
else
// if the 'id' in the URL isn't valid, or if there is no 'id' value, display an error
{
echo 'Error!';
}
}
?>
I am wanting to replace the status text filed with a drop down list of options.
