Hi I am a student who is fairly new to PHP and MySQL. I have been working on creating a registration page for a website and I'm getting the following warnings when I've tested the page:   Warning: mysqli_fetch_array() expects parameter 1 to be mysqli_result, boolean given in /home/ed12e2w/public_html/COMM2735/dynamic_website/registration.php on line 74

Warning: mysqli_free_result() expects parameter 1 to be mysqli_result, boolean given in /home/ed12e2w/public_html/COMM2735/dynamic_website/registration.php on line 80   I think that my query has failed but I'm not completely sure on what to change in order to solve this.   Here is the section of code I'm having problems with:     Attached Files  register.php   733bytes   4 downloads

Someone help me in this problem please??

Guys thanks for helping me solve the problem i had but now i have another problem and i am lost. i have included the code below for you to have overview.

On the home page the url shows how it should be: http://localhost/board/italian.php?country=Italian
BUT 
When you mouse over the NEXT link to go to next page you get this : http://localhost/board/?page=1&country=Italian  and then an error 404 when you click on the link
page = 1  no matter if you are mousing over link for page 5 or 2

This is the code:

Hi,
i use mysql_real_escape_string() function when insert in db, but when echo i use htmlentities($var, ENT_QUOTES, "UTF-8")
Now problem is '\ in that text.

In db it write text with single quote with \, example That\'s wrong, and when echo it show just the same like in db..
How can i fix this ?

Hi there,

I have a map of America made in flash, where you click on a state and the page should display the SQL database information for that state in the HTML table - but instead all it shows is the first entry of the database regardless of which state you click and it doesn't display the 2 radio buttons.

My code is as follows

Flash Actionscript 3 (just showing one state)
Code: [Select]
function waClick(event:MouseEvent):void {
var waURL:URLRequest = new URLRequest("restaurants.php?state=Washington");
navigateToURL(waURL, "_self");
}
wa_btn.addEventListener(MouseEvent.CLICK, waClick);
PHP code

Code: [Select]
<?php
  include("mvfconnect.php");
  $theChoice = $_GET['state'];
  $query = "SELECT * FROM restaurants WHERE" .$theChoice;
  $result = @ mysql_query($query);
  if (!$result) {
   $message="Unfortunately we are having problems with this page, we promise to have it fixed as soon as possible";
    die($message);
  }
  $num = mysql_num_fields($result);
  $i=0;
  while ($row = mysql_fetch_array($result, MYSQL_ASSOC)){
   $show1=substr($row['state'],0,50)."...";
   $show2=substr($row['city'],0,50)."...";

I have used this code before and it has worked fine, can someone please help me out! 

 
 

Okay, so i'm using the basic php mysql insert into function but I have a strange (or maybe not so strange, I just don't get it..) problem..

I have two columns (do you call them columns? I don't really know for sure, whatever things that are in a table whatsoever).

Name and Trailer.

EDIT: they are TEXT's if that matters

Name is really nothing important, just the name.
But I want to embed trailers.. If I embed the Megavideo code below:

Code: [Select]
<object width="400" height="300"><param name="movie" value="http://www.megavideo.com/v/8UZFURZQ2b55ada04d73ae65c726a5383b9ee9d9"></param><param name="allowFullScreen" value="true"></param><embed src="http://www.megavideo.com/v/8UZFURZQ2b55ada04d73ae65c726a5383b9ee9d9" type="application/x-shockwave-flash" allowfullscreen="true" width="400" height="300"></embed></object>
Everything works fine, no problems and no bullshit.

But.. if I for an example try to embed this one (NovaMov):

Code: [Select]
<iframe style='overflow: hidden; border: 0; width: 400px; height: 300px' src='http://embed.novamov.com/embed.php?width=400&height=300&v=xngq7u8yejwbt' scrolling='no'></iframe>
It doesn't work. It just doesn't insert. Is inserting an "iframe" a problem or something? I just don't get why the hell it would do this?

Does anyone know anything about this? If so i'd be eager and very thankful to hear why and how to fix it.

thanks in advance

Code: [Select]
<?php
require('config.php');
$sql = "SELECT m.Title as title , f.Reg_URL as reg
        FROM
                website_main as m   
                JOIN               
                website_front as f               
         LIMIT 0,01
              ";


$result = @mysql_query($sql) or die(mysql_error());
echo "<table border='3'>";
echo "<font size='9'><tr> <th><FONT COLOR=red><center>Title</center></font></th> <th><FONT COLOR=red>reg</th> </tr></font>";
// keeps getting the next row until there are no more to get
while($row = mysql_fetch_array( $result )) {
   // Print out the contents of each row into a table
$reg = $row['reg'];
      echo "<tr><td bgcolor=''><center>";       
   echo $row['title'];
   echo "</td><td bgcolor=''><center>";
echo '.$reg.';
   echo "</td></tr>"; 
}
?>
I got a problem i try to use an attribute for $reg but only appears as .$reg. on website anyone know why?
Parts i have problems with are $reg = $row['reg']; and echo '.$reg.';.

thank you

Elo,
I'm creating a very simple image list that is function generated which pulls the source from a table in my database,
this is my code

Code: [Select]
$output = "<ul>";
$img_src = get_all_image_src($sel_event['id']);

while($src = mysql_fetch_array($img_src))
{
for($i=0;$i <= 9; $i++)
{

                $output .= "<li>";
$output .= "<a";
$output .= " class ='album'";
$output .= " rel='group'";
$output .= " href='/images/gallery/'" . $src['img_src'] . $i;
$output .= ".jpg";
$output .= " title='sample 1'";
$output .= ">";

//Image Thumb
$output .= "<img";
$output .= " src='/images/gallery/'";
$output .= $src['img_thumb_src']. $i . ".jpg";
$output .= "alt='image01' ";
$output .= "title='sample title' />";
$output .= "tae";
$output .= "</a>";
       
                $output .= "</li>";
}
}

    $output .= "</ul>";
return $output;

and the img src doesnt seems to add up...
my folder structure is Sandbox>image>gallery>2011>Mall>Event>Thumbs where Sandbox is the main directory.
i tried echoing the $src['img_src'] and it displays correctly the data to be added (which is 2011/Mall/Event/ plus $i and a .jpg) ..
sorry noob here...
any thoughts?
am i missing a simple detail?

Hi, im creating a script for a website that will list products, i have the basic construct which lists the products from the database but it lists then vertically, i have set the width of each 'product' to 200px so i could have around 3 colums and many rows.

can anybody advise how i would make them run vertically aswell as horizontally?

my code below:

<?php
include_once("include/globals.php");

?>

<div id="main">

    <?php 
        
        //Get database Results
        $result = mysql_query("SELECT * FROM Products WHERE is_active = 1") or die(mysql_error());
        
        //keeps getting the next row until no more records
        while($row = mysql_fetch_array($result))    {
        
        //echo results ($result)
        echo '<div id="holder">';
        echo '<div class="title">' . $row['Name'] . '</div>';
        //insert image here
        echo '<div class="image">';
        echo '<img src="' . $row['image'] . '" width="100" alt="">';
        echo '</div>';
        
        echo '<div class="tag_line">';
        echo $row['Tag_Line'];
        echo '</div>';
