PHP - A Simple Coding Help.

Hi everyone,

I'm trying to select either a class or an id using PHP Simple HTML DOM Parser with absolutely no luck.  My example is very simple and seems to comply to the examples given in the manual(http://simplehtmldom.sourceforge.net/manual.htm) but it just wont work, it's driving me up the wall.

Here is my example: http://schulnetz.nibis.de/db/schulen/schule.php?schulnr=94468&lschb=

I think the HTML is invalid: i cannot parse it.

Well i need more examples - probly i have overseen something!

If anybody has a working example of Simple-html-dom-parser...i would be happy.
The examples on the developersite are not very helpful.

Hello, im very green to php and I am having trouble creating a simple log in script. Not sure why this is not working, maybe a mysql_query mistake? I am not receiving any errors but nothing gets updated in the members table and my error message to the user displays.  any help is appreciated! here is my php:


<?php
session_start();

$errorMsg = '';
$email = '';
$pass = '';

if (isset($_POST['email'])) {
   $email = ($_POST['email']);
   $pass = ($_POST['password']);
   
   $email = stripslashes($email);
    $pass = stripslashes($pass);
   $email = strip_tags($email);
   $pass = strip_tags($pass);
   
if ((!$email) || (!$pass)) {
   $errorMsg = '<font color="#FF0000">Please fill in both fields</font>';
}else {
   include 'scripts/connect_db.php';
   $email = mysql_real_escape_string ($email);
   $pass = md5($pass);
   
   $sql = mysql_query("SELECT * FROM members WHERE email='$email' AND password='$pass'");
   
   $log_check = mysql_num_rows($sql);
   
if ($log_check > 0) {
    while($row = mysql_fetch_array($sql)) {
      
      $id = $row["id"];
      $_SESSION['id'];
      $email = $row["email"];
      $_SESSION['email'];
      $username = $row["username"];
      $_session['username'];
      
      mysql_query("UPDATE members SET last_logged=now() WHERE id='$id' LIMIT 1");
      
   }//Close while loop
   echo "You are logged in";
             exit();
}
else {
   $errorMsg = '<font color="#FF0000">Incorrect login data, please try again</font>';
}


     }
}
?>



and the form:

<?php echo $errorMsg; ?>
<form action="log_in.php" method="post">
Email:<br />
<input name="email" type="text" /><br /><br />
Password:<br />
<input name="password" type="password" /><br /><br />
<input name="myBtn" type="submit" value="Log In" />
</form>

Hi can someone pls help, im tryin a tutorial but keep getting errors, this is the first one i get after registering.

You Are Registered And Can Now Login
Warning: Cannot modify header information - headers already sent by (output started at /home/aretheyh/public_html/nealeweb.com/regcheck.php:43) in /home/aretheyh/public_html/nealeweb.com/regcheck.php on line 46

Hey,

I would there be a way i could create a form in which upon entering a domain name/URL it will tell you how many connections there are to the site and how many (if any) MySQL queries are running?

If I add this line to a wordpress footer it displays the number of sql queries.

Code: [Select]
&lt;?php echo get_num_queries(); ?&gt; queries in &lt;?php timer_stop(1); ?&gt; seconds.
Any help is greatly appreciated.

Thanks.

Hi All

I am fairly new to the PHP world so please excuse my ignorance. (I am trying!)

Basically I bought a commercially available PHP script and created my own script to work alongside the bought one.  What happened then is that the developers of the script I bought released a new version of the software. My script no longer works and is throwing up the following error

PHP Fatal error:  Using $this when not in object context in C:\wamp\www\classifieds\system\core\System.php on line 175

I've worked out that the  script fails on this line, in the new version of the software.

$dbhost = System::getSystemSettings('DBHOST');

On review of the commercial script's coding, I noticed that where the old version used the syntax above, the new version uses a syntax as shown below

$this->appContext->getSystemSettings('DBHOST');

So I went and modified my script (mismatched.php) to read as follows

$dbhost = $this->appContext->getSystemSettings('DBHOST');

But im now getting the following errors

PHP Parse error:  syntax error, unexpected T_REQUIRE_ONCE, expecting T_FUNCTION in C:\wamp\www\classifieds\admin\mismatched.php on line 5

I'd appreciate any ideas you may have that could help me get my script (mismatched.php) working again.
Thanks again

Could some one please guide me to a possible script to accomplish this task....

I want to pull and display two separate things that are in two separate places and display them as one link on a page. I have figured out how to display the data to a page and also how to display the files to a page separately but need to accomplish this and join the 3 things together.

I have a library table in the database that stores the product_code and product_name
example:

pk-pen(product_code) traditional fountain pen(product_name) ---- (this is where I need to get the data from)

Then I have a folder on the server that is called library that has the pdf files in it. Each pdf file has the same name as the product_code that is in the database.
example:
pk-pen_ins.pdf

What I need to accomplish is grabbing the product_code and product_name for the database and then go to the folder on the server and add the correct pdf file with that data and display it as a link on a page for customers to download. bee struggling with this and pasted code that i have to do each task separately but cant seem to get it all in one script to do the above. I understand that this could be asking for a lot here but I am new to this and would be forever in debt to your kindness. Thanks on this in advance

I know this form doesn't really work, but the FTP part *should* work.  I select a file, and click upload, Chrome shows the file is uploading and gets to 100% then fails.  I'm getting "File Upload Failed!" on line 112 every time, but I can't seem to figure out why.  I'm hoping a pair of expert eyes can spot it quickly.

Code: [Select]
Upload A File:

Hi guys,   I am needing some help of how to place the coding as I can not get it to work.    --   Basically I am building a website for the local motorclub and want some code that will "add up" each persons results.   Here is what I have come up with but it does not work;

<?php $total = mysql_fetch_array("SELECT cat1 + cat2 + cat3 + cat4 + cat5 + cat6 AS total FROM results") ?>
					  <?php
$cautotest_results = mysql_query("SELECT * FROM results WHERE cat ='1' ORDER BY cattotal DESC");
if(mysql_num_rows($cautotest_results) == '') { echo "<p>No Results Available."; } else {


echo "<table width=\"800\" border=\"0\" cellpadding=\"2\" cellspacing=\"2\" class=\"greywritinglight\" align=\"center\">
<tr align=\"center\">
<td>Competitor</td>
<td>Vehicle</td>
<td>Class</td>
<td>Skipton</td>
<td>Weston</td>
<td>King Bros</td>
<td>Normans</td>
<td>Norwood</td>
<td>Uniroyal</td>
<td>Total</td>
</tr>";

$x=1; 
while($results_row = mysql_fetch_array($cautotest_results))
{
			if($x%2): $rowbgcolor = "#FFFFFF"; else: $rowbgcolor = "#EEEEEE"; endif;
echo "<tr align=\"center\" bgcolor=\"" .$rowbgcolor. "\">";
echo "<td>" . $results_row['competitor'] . "</td>";
echo "<td>" . $results_row['catvehicle'] .  "</td>";
echo "<td>" . $results_row['catclass'] . "</td>";
echo "<td>" . $results_row['cat1'] . "</td>";
echo "<td>" . $results_row['cat2'] . "</td>";
echo "<td>" . $results_row['cat3'] . "</td>";
echo "<td>" . $results_row['cat4'] . "</td>";
echo "<td>" . $results_row['cat5'] . "</td>";
echo "<td>" . $results_row['cat6'] . "</td>";
echo "<td>" . $total . "</td>";
echo "</tr>";
$x++;
}
echo "</table>";
}
?>

Its the top line of coding... and the echo .total. at the bottom.     If you could please correct me I would be ever so grateful.   If you need more info please just ask. All help is appreciated.   JTM.

I'm trying to update a field in my MySQL but instead of updating this makes the field BLANK.

my code:
$SomeVar = $_POST['finco'];
mysql_query("UPDATE  c_applicants SET streetz='$cts' WHERE username = '".$SomeVar."'");

$result = mysql_query($query);
