Hello Everyone

This is a basic script for posting to a database. I'm not sure why it doesn't work. Can anyone tell me why?

 

<?php
require('config.php');
if(isset($_GET['id']) == TRUE && isset($_GET['td'])==TRUE){
if(is_numeric($_GET['id'])==FALSE || is_numeric($_GET['td'])==FALSE) {
	$error = 1;
}
if($error == 1){
	header("Location: " . $config_basedir);
}
else{
	$validentry = $_GET['id'];
	$validtd = $_GET['td'];
}
}
else{
$validentry = 0;
}
if($_POST['submit']) {
$db = mysql_connect($dbhost,$dbuser,$dbpassword);
mysql_select_db($dbdatabase, $db);
if(!$db){
	die('FAILED TO OPEN DATABASE:' . mysql_error());
}

$sql = "INSERT INTO todo(id, topic, date, comment) 
		VALUES (" . $validentry . ", '" . $_POST['topic'] .
		"', '" . $_POST['date'] . "', '" . $_POST['comment'] . "');";

$result=mysql_query($sql);
if(!$result){
	die('FAILED TO INPUT INTO DATABASE:' . mysql_error());
}
header("Location: index.php?id=" . $validentry);
}

?>
<center>
**All dates must be inputted in the YYYY-MM-DD format** <br>
<br>
<form action="<?php echo $SCRIPT_NAME . "?id=" . $validentry; ?>" method="post">
<table>

<tr>
<td>Topic</td>
    <td><input type="text" name="topic"></td>
</tr>
<tr>
<td>Date</td>
    <td><input type="text" name="lname"></td>
</tr>
<tr>
<td>Comment</td>
    <td><input type="text" name="address"></td>
</tr>
<tr>
<td></td>
    <td><input type="submit" name="submit" value="Submit Note"></td>
</tr>
</table>
</form>
</center>

This has worked for me:

<?php 
$topic = $_POST['topic'];
$date = $_POST['date'];
$comment = $_POST['comment'];
sql = "INSERT INTO todo(id, topic, date, comment) 
         VALUES ('$validentry', '$topic', '$date', '$comment')"; ?>

This way the double quotes don't get confused with the single quotes.

you should really have error_reporting on.

 

would have picked up the extra ; at the end of your query:

 

$sql = "INSERT INTO todo(id, topic, date, comment) 
         VALUES (" . $validentry . ", '" . $_POST['topic'] .
         "', '" . $_POST['date'] . "', '" . $_POST['comment'] . "');"; //;"; is no good;

 

should be:

 

$sql = "INSERT INTO todo(id, topic, date, comment) 
         VALUES (" . $validentry . ", '" . $_POST['topic'] .
         "', '" . $_POST['date'] . "', '" . $_POST['comment'] . "')";

What does happen in the browser when you submit the form? Does it just redisplay the form or does it redirect to index.php?

 

For debugging purposes, please add the following two lines of code immediately after your first opening <?php tag -

 

ini_set("display_errors", "1");
error_reporting(E_ALL);

 

FYI, the extra semicolon ; on the end of the query statement would normally be used when you execute the query directly against the mysql server, but it is optional when executing a query through php. It is not a php or an sql error.

Once you start debugging your code on a system with error_reporting set to E_ALL and display_errors set to ON, you will find that your date and comment fields in your form don't have the correct name="..." attributes.

When i submit the code it redirects to index.php and looks like nothing ever changed.

 

The first thing i saw was this message on top of my script:

 

Notice: Undefined index: submit in C:\xampp\htdocs\sites\smart\addtodo.php on line 20

 

when i try to submit something, the page 404's with this in the URL box:

 

http://localhost/sites/web/%3Cbr%20/%3E%3Cb%3ENotice%3C/b%3E:%20%20Undefined%20variable:%20SCRIPT_NAME%20in%20%3Cb%3EC:%5Cxampp%5Chtdocs%5Csites%5Csmart%5Caddtodo.php%3C/b%3E%20on%20line%20%3Cb%3E43%3C/b%3E%3Cbr%20/%3E?id=1

 

I'm guessing it has a problem with $SCRIPT_NAME or ?id=1... Any help wit clarification?

Seven years ago $SCRIPT_NAME would have been valid. Either use $_SERVER['SCRIPT_NAME'] or you can just leave off the script/file name in the action="..." attribute and use -

 

action="?id=<?php echo $validentry; ?>"
