Some problems with GET

July 25, 2013

Hello,

<?php
require('../db_connect.php');
mysql_select_db('news');
$headline = $_POST['headline'];
$author = $_POST['author'];
$text = $_POST['text'];
$id = $_GET['id']; - My Problem
if(isset($_POST['Aktualisieren']))
{
	$head2 = $_POST['headline'];
	$text2 = $_POST['text'];
	$author2 = $_POST['author'];
	$date2 = date('Y-m-d');
	if ($head2 !="" || $text2 !="" || $author2 !="")
	{
		$updatequery = "UPDATE news SET headline='$head2', author='$author2', text='$text2', date='$date2' WHERE id='$id'";
		mysql_query($updatequery) or die('error');
		printf($updatequery);
		//echo 'Ersetzt';
		//header("Location: http://localhost/project1/News/news2.php");
	}
	else
	{
		echo 'Bitte fülen Sie alle Felder aus';
	}
}

?>




<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Submit</title>
<script src="../ckeditor/ckeditor.js"></script>
</head>
<body>

<?php

$query = mysql_query ("SELECT * FROM news WHERE id='$id'");
while($row = mysql_fetch_array($query))
{
echo "<form action=update2.php method=POST>";
echo "<tr>";
echo "<td><input type='hidden' name='headline' value='" .	$row['headline'] . "'> </td>";
echo "<td><input type='hidden' name='author' value='" . $row['author'] . "'> </td>";
echo "<td><input type='hidden' name='text' value='" .	$row['text'] . "'> </td>";
echo "<td><input type='submit' name='update' value='get'" . " </td>";
echo "</form>";
}
echo "<form action=update2.php method=POST>";
echo "<tr>";
echo "<td> Überschrift: </td> <input name='headline' type='text' value='$headline' /> <br />";
echo "<td> von: </td> <input name='author' type='text' value='$author' /> </td><br />";
echo "<p> <textarea name='textar'>$text</textarea></p><br />";
?>
<script>
    CKEDITOR.replace( 'textar',
		{
			toolbar : 'basic',
			uiColor : '# 9AB8F3',
			enterMode : CKEDITOR.ENTER_BR,
			shiftEnterMode : CKEDITOR.ENTER_P
		});
</script></td>
<?php
echo "<input name='Aktualisieren' type='submit' value='Aktualisieren'/>";
echo "</tr>";
echo "</form>";
?>

</body>
<link href='../css/main.css' rel="stylesheet" type="text/css" />
</html>

from the page news2.php I get the ID, but when I use this form

{
echo "<form action=update2.php method=POST>";
echo "<tr>";
echo "<td><input type='hidden' name='headline' value='" .	$row['headline'] . "'> </td>";
echo "<td><input type='hidden' name='author' value='" . $row['author'] . "'> </td>";
echo "<td><input type='hidden' name='text' value='" .	$row['text'] . "'> </td>";
echo "<td><input type='submit' name='update' value='get'" . " </td>";
echo "</form>";
}

the ID diseappears and I need it for the $updatequery

$updatequery = "UPDATE news SET headline='$head2', author='$author2', text='$text2', date='$date2' WHERE id='$id'";

How could I fix it?

Sorry for my english.

EDIT:

$query = mysql_query ("SELECT * FROM news WHERE id='$id'");
is working.

The answer is no different from the one in your other thread. If you want to pass a variable through GET, it must be in the URL. The difference is the URL is in the form's action.

Bad news sir.

July 25, 2013

I tried to fix it this way.

$query = mysql_query ("SELECT * FROM news WHERE id='$id'");
while($row = mysql_fetch_array($query))
echo "<form action=update2.php method=POST>";
echo "<tr>";
echo "<td> Überschrift: </td> <input name='headline' type='text' value=".$row['headline']." /> <br />";
echo "<td> von: </td> <input name='author' type='text' value='".$row['author']."' /> </td><br />";
echo "<p> <textarea name='textar'>$row[text]</textarea></p><br />";
?>

.$row['headline'].

.$row['author'].

$row[text]

do not output the text.

Any ideas?

i fixed the form this way:

<?php

$query = mysql_query ("SELECT * FROM news WHERE id='$_GET[id]'");
while($row = mysql_fetch_array($query)){
echo "<form action=update2.php method=post>";
echo "<td> Titel:<input type='text' name='headline' value='" .	$row['headline'] . "'> <br /> </td>";
echo "<td> Autor:<input type='text' name='author' value='" . $row['author'] . "'> </td>";
echo "<p><textarea name='textar'>".$row['text']."</textarea></p><br />";
?>
<script>
    CKEDITOR.replace( 'textar',
		{
			toolbar : 'basic',
			uiColor : '# 9AB8F3',
			enterMode : CKEDITOR.ENTER_BR,
			shiftEnterMode : CKEDITOR.ENTER_P
		});
</script></td>
<?php
echo "<input name='Aktualisieren' type='submit' value='Aktualisieren'/>";
echo "</tr>";
echo "</form>";
}
?>

but still cant fix this

		$updatequery = "UPDATE news SET headline='$head2', author='$author2', text='$text2', date='$date2' WHERE id='$_GET[id]'";
		mysql_query($updatequery) or die('error');
		printf($updatequery);

Notice: Undefined index: id in C:\xampp\htdocs\Project1\News\update2.php on line 12
UPDATE news SET headline='asdf', author='admin', text='sdfhsdg', date='2013-07-25' WHERE id=''
Notice: Undefined index: id in C:\xampp\htdocs\Project1\News\update2.php on line 39

When update2.php was called, did you pass the id variable? For example:

...update2.php?id=3

I just re-read the post. The GET variable needs to be added to the form tag as boompa suggested.

<?php
echo "<form action='update2.php?id={$row['id']}' method='post'>";
?>

Of course, $row['id'] would need to be changed to whatever variable you're using within the form script.
