URL request to load article

[PlagueInfected]

I don't know what I'm doing wrong here.

 

I'm trying to do a method to where if id=2 than the db will select the articleid from the table, than load articleid2's contents.

 

 

so if I call this URL

 

http://mysite.com/articles.php?id=1

 

it will load article 1

 

than if I call this URL

 

http://mysite.com/articles.php?id=2

 

it will load article 2

 

Here's my form code

 

<fieldset>
   <legend>Adding KB article on <?php echo date("l, F d, Y");?> on <?php echo $_SERVER['HTTP_HOST']; ?></legend>
     <form action="../admin/knowledge_base.php" method="POST">
       <input type="hidden" name="date" value="<?php echo date("l, F d, Y"); ?>" border="0" />
       <label>Article ID</label>
       <input type="text" name="articleid" />
       <br />
       <?php
$connect = mysql_connect("localhost", "myusername", "mypassword") or die ('Error:' .mysql_error());

if (!$connect) {
  die('Could not connect: ' . mysql_error());
  }
  
mysql_select_db("mydatabse", $connect);

$query = "SELECT articleid, COUNT(articleid) FROM knowledge_base"; 

$result = mysql_query($query) or die(mysql_error());

// Print out result
while($row = mysql_fetch_array($result)){
echo "There are currently " . $row['COUNT(articleid)'] ." article(s)" . "\n";
  if  ($row['COUNT(articleid)'] == "0") {
     $row['COUNT(articleid)'] = "0";
	 }
}
?>

       <br />
      <label> Article Name</label> <input type="text" name="articlename" id="admin_subject" />
        <br />
      <label>Article Information </label><br />
         <textarea name="articleinfo"  id="admin_textarea"></textarea>
        <br />
         <input type="submit" value="submit" />
         <input type="reset" value="reset" />
    </form>
</fieldset>

 

here is my write code

 

<?php 
$articleid = $_POST['id'];
$articlename = $_POST['articlename'];
$articleinfo = $_POST['articleinfo'];
$date = $_POST['date'];

$error = "no content inserted on update page";

//if not content is plugged in echo error
if (!$articlename && !$articleinfo) {
echo "Error: " . $error . "\n";
}


//MySQL connection
$connect = mysql_connect("localhost", "myusername", "mypassword") or die ('Error:' .mysql_error());

if (!$connect) {
  die('Could not connect: ' . mysql_error());
  }
  
  if ($connect && !$articlename && !$articleinfo &&!$articleid) {
  die ('No information submitted to post to DB');
  }
  
mysql_select_db("mydatabse", $connect);

//Created MySQL 'knowledge_base' table
$sql = "CREATE TABLE knowledge_base
(
articleid(4),
articlename(20),
articleinfo(2000),
date(20),
)";

mysql_query($sql,$connect);

mysql_query("INSERT INTO knowledge_base (articleid,articlename, articleinfo, date)
VALUES ('$articleid', '$articlename', '$articleinfo', '$date')");

echo "Article published on " . $date . "\r\n" . ' <a href="javascript:history.back(-2);">Click to go back!</a>';

  mysql_close($connect);
  
  ?>

 

and here is my calling code with the statements

 

<?php
/* Knowledge Base */
$id = $_GET['id'];

$article_id_call = $row['articleid'];

$connect = mysql_connect("localhost", "myusername", "mypassword");
if (!$connect) {
  die('Could not connect: ' . mysql_error());
  }
  mysql_select_db("mydatabase", $connect);
  
  $result = mysql_query("SELECT articleid FROM knowledge_base");
  
  mysql_close($connect);

if ($id == $article_id_call) {
$connect = mysql_connect("localhost", "myusername", "mypassword");
if (!$connect) {
  die('Could not connect: ' . mysql_error());
  }
  mysql_select_db("mydatabse", $connect);
  
  $result = mysql_query("SELECT * FROM knowledge_base ORDER BY articlename");
  
  while($row = mysql_fetch_array($result)) {
     echo "<h1>" . $row['articlename'] . "</h1>" . "\n";
     echo "  <div id='base'>" . $row['articleinfo'] . "</div>" . "\n";
  }
  
  mysql_close($connect);
}

elseif ($id == !$article_id_call) {
   echo "this article does not exist!";
   }

else {
   echo "knowledge base test.";
   }

?>

Why do you insist on closing the connection? I would remove all of the mysql_close from your script, as unless you are switching databases it is not necessary as PHP will automatically close the connection for you.

 

On another note, perhaps this tutorial I wrote will help you out:

Fetch MySQL Data Using PHP and GET
