PHP - Log In App That Adds Info To Url (dummies Book Example)

>subject.

Why does it do this and how can I fix it?

Example:

I write

<?php
echo"hello world!";
?>
other stuff/html here

After I submit I see this:


<?php
echo"hello world!";
?>
other stuff/html here

I'm using Geshi w/ highlight_string

This also happens if I use htmlspecialchars + highlight_string

I'm trying to automatically change a math equation so that the solution is an even number:

It is at first complicated but I'm progressing.

This is my first attempt at accomplishing what I'm trying to accomplish.

 if (($sol != round($sol)) && ($x1 < $x2)) {

 
/***********************************************************/
function round_up ($sol, $x1, $op, $x2) {

for ($x1 = $x1; $sol < round($sol); $x1++) {

switch ($op) {

case '+' : $sol = $x1 + $x2; break;

case '-' : $sol = $x1 - $x2; break;

case '*' : $sol = $x1 * $x2; break;

case '/' : $sol = $x1 / $x2; break;

}

}

return (array ($sol, $x1, $op, $x2));

}
/**********************************************************/

$round_array = round_up($sol, $x1, $op, $x2);

echo "after for loop: $round_array[1] $round_array[2] $round_array[3] = and sol: $round_array[0] <br /><br />";

 }


If the solution of the equation is not a round number, and if the first number is smaller than the other, than increase the first number until the solution is a round number.

It is a very primitive solution, but I'm learning as I go and I'll try to make it more intelligent. But to my problem, the above script outputs following values:

Code: [Select]
first calc: 3 / 5 = ?

first sol: 0.6

after for loop: 6 / 5 = and sol: 1

The script will increase the first number about 1 digit more, and that is exactly my problem, since that way the equation makes no sense.

The condition of the for loop is, increase $x1 till $sol is SHORTLY before the next rounded number, when it is has reached the next rounded number STOP.

Thus $x1 should be 5 in the above example, because 5/5 = 1.

IT seems that after $sol has reached the next round number, the for loop will go one more time over the variables, and THEN it will stop.

How can I solve this problem?

Hey Guys,

I've got a small script that displays latest news.

It is supposed to show just the title of the news item in a list, however it shows the content at the bottom of the code...
This is my page
<ul>
<?php
        $args= array(
        'news_items' => 500,
        'title' => TRUE,
        'content' => FALSE,
        'before_title' => '<li>',
        'after_title' => '</li>'
   );

jep_latest_news_loop($args);
echo '</ul>';
?> <br>TEST<br>

But this is the output

Any ideas what is dumping the extra code?

Hello, Experts! Need you advice.

Here is the code:

<?php

if ($var == "")  {
        echo "text";
   }
     if ($var == "*")  {
        echo "text"; }
   else if ($var != "")
   {
        
$query = "SELECT * FROM bd WHERE ....."; 
$data = mysql_query($query) or die(mysql_error());
       $anymatches=mysql_num_rows($data);
        if ($anymatches != 0) {
       echo "text";
        while($row = mysql_fetch_array($data))
        {
            echo "text";      
        }    
         } 
        if ($anymatches == 0) {      
         $query2 = "SELECT * FROM bd WHERE....."; 
      $data2 = mysql_query($query2) or die(mysql_error());
       $anymatches2=mysql_num_rows($data2);
       if ($anymatches2 != 0) {             
 echo "text"
       else
       {
              
          mysql_query("INSERT INTO notfound (notfound) VALUES ('$var')") or die(mysql_error());    
           } }  } ?>

The last line adds two identical lines to my table. Do I run it twice? Thanks in advance!

Can anyone tell me what's making  this code put an extra entry in the database?Whatever the number of looped students being added, it adds another row with nothing but the registrationid entered.

Code: [Select]
<?php
// connect to database 
include("databaseconn.php"); 

// store all posted intemnos and descriptions in local arrays 
$fname = $_POST['fname']; 
$lname = $_POST['lname']; 
$phone = $_POST['phone']; 
$email = $_POST['email']; 
$bdate = $_POST['bdate'];
$bdate2 = $_POST['bdate2'];
$bdate3 = $_POST['bdate3'];
$wid = $_POST['wid']; 
$rid = $_POST['reg_id'];
$reg_alone = $_POST['reg_alone'];

$_SESSION['workshops']=$wid;
?>


<?

if(sizeof($_POST['fname'])) {
// loop through array
$number = count($fname);
for ($i=0; $i<=$number; $i++)
{
    // store a single item number and description in local variables
    $fnames = $fname[$i];
    $lnames = $lname[$i];
    $phones = $phone[$i];
    $emails = $email[$i];
    $bdates = $bdate[$i];
    $bdates2 = $bdate2[$i];
    $bdates3 = $bdate3[$i];
    $wids = $wid[$i];
    $rids = $rid[$i];
echo "echod ".$bdates2."and<br>";
print_r($bdates2);
$query_insertItemWorkshop = "INSERT INTO tbl_attendees (attendee_fname, attendee_lname, attendee_registrationid, workshop_id, attendee_email, attendee_telephone, attendee_bday, attendee_bmonth, attendee_byear) VALUES ('$fnames', '$lnames', '$reg_alone', '$wids', '$emails', '$phones', '$bdates', '$bdates2', '$bdates3')";

echo "query: ".$query_insertItemWorkshop;
$dberror = "";
$ret = mysql_query($query_insertItemWorkshop);
