Hi every1! Im new in MySQLI and PHP. Trying to create an editable table, but my code is not working. I'm getting no errors or warnings. It just dont update or add records. Im getting my form with all values but after clicking submit nothing change. The records stil the same. Here is my code:
<?php
//connect
include ("db/connect.php");
//create new/edit
function renderForm ($nameS = '', $nummerS = '', $dateS='', $stuckS='', $error='',$id=''){
?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title> <?php if ($id != '') { echo "Edit Record"; } else { echo "New Record"; } ?></title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
</head>
<body>
<h1> <?php if ($id != '') { echo "Edit Record"; } else { echo "New Record"; } ?></h1>
<?php if($error !=''){
echo "<div style='padding:4px; border:1px solid red; color:red'>" . $error . "</div>";
}?>
<form action="" method="post">
<div>
<?php
if ($id !=''){?>
<input type="hidden" name="id" value=" <?php echo $id; ?>"/>
<p>ID: <?php echo $id; ?></p>
<?php } ?>
<strong>Name: </strong> <input type="text" name="name" value=" <?php echo $nameS; ?>"/><br/>
<strong>Nummer: </strong> <input type="text" name="nummer" value=" <?php echo $nummerS; ?>"/><br/>
<strong>Date: </strong> <input type="text" name="date" value=" <?php echo $dateS; ?>"/><br/>
<strong>Stuck: </strong> <input type="text" name="stuck" value=" <?php echo $stuckS; ?>"/><br/>
<input type="submit" name="submit" value="Submit" />
</div>
</form>
</body>
</html>
