PHP - Problem Trimming Variable

Code: [Select]
<?
$out = preg_replace('/^(.{701}[^.]*).*/i','$1.',$detrsltnewsrow[news_desc]);
echo $out;
?>

</td></tr><tr><td colspan="2" class="para" style="padding-left:10px;">

<?=
substr(stripslashes(trim($detrsltnewsrow[news_desc])),701)
?>
                                             
</td></tr>

I have the above snippet.. The first php statement, basically grasp the first 701 characters with the closet next stop "." character and out puts it. then out puts the HTML tags

I have a problem with the second statement. I want to output anything after what has been outputted by:
Code: [Select]
<?
$out = preg_replace('/^(.{701}[^.]*).*/i','$1.',$detrsltnewsrow[news_desc]);
echo $out;
?>

So need the correct syntax for
Code: [Select]
<?=
substr(stripslashes(trim($detrsltnewsrow[news_desc])),701)
?>
Currently it breaks at exactly the 701 character, want it to continue from the sentence the first code ended in.

I'm not sure what is going on in this code, but for some reason it is not echoing my variable. I'm probably just having a total brain fart right now.
Code: [Select]
<?php

<?php

$opponent_check = isset($_POST['player_username']);

$session = isset($_SESSION['user']);

if($opponent_check){

include_once('connect.php');

$find_player = "SELECT * FROM stats WHERE Username = '$session'";
$s = mysql_fetch_array(mysql_query($find_player)) or trigger_error(mysql_error());

$player = $s['Username'];
$player_HBS = $s['HBS'];
$player_level = $s['Level'];
$player_level_image = $s['Level_Image'];
$player_skill = $s['Skill'];
$player_attack = $s['Attack'];
$player_defense = $s['Defense'];
$player_strength = $s['Strength'];
$player_speed = $s['Speed'];
$player_accuracy = $s['Accuracy'];
$player_range = $s['Range'];

echo $player;

}else{

echo "

You didn't start a battle.<br/><br/>
<a href='index.php'>Back to Matchmaking</a>
<br/><br/>

";

}

?>

?>

My error is: Notice: in C:\xampp\htdocs\halobattles\headtohead.php on line 277 which is the fetch array line.

Hi guys,

I have a bit of a problem,

Im using php and mysql and have succeded in storing variables inside of a URL:


echo "<a href='report.php?id=$varmemberid&colour=$varcolour'>test</a> ";


i retrieve varmemberid and colour from the mysql database:


$tbl_name = "members";

mysql_select_db($db_name) or die (mysql_error());

$query="SELECT * FROM $db_name ORDER BY  `members`.`the_members` ASC";
$result=mysql_query($query);


$num=mysql_numrows($result);

$i=0;
while ($i < $num) {
$varmemberid=mysql_result($result,$i,"member_id");
$varcolour=mysql_result($result,$i,"colour");


that works all fine and dandy for numbers eg: "123" however if i go to insert a member id of "123t" i get this error:
Code: [Select]
Warning: mysql_result() [function.mysql-result]: Unable to jump to row 0 on MySQL result index 12 in /home/flashx/public_html/login/report-header.php on line 47

 im guessing it has something to do with the 'int' in this line:
$memberid = (int) $_GET['memberid'];

how do i fix this?

Cheers

So. I wrote this class that redirects a user to a new url:

Code: [Select]
<?php
class PotentGate{
private $endURL, $sourceURL = 'http';

private function Gate_setURL(){
//THE BLOCK BELOW WIL ULTIMATELY REFERECE A DATABASE BACKEND FOR DESTINATION URLS.
if ($this->sourceURL=="http://blah.com/blah/misc.php"){$this->endURL="http://blah.com/blah/misc2.php?r=" . $this->Gate_sourceURL;}
else {}
}

public function Gate_getURL(){
$this->Gate_sourceURL();
echo $this->sourceURL . "<br />";

$this->Gate_setURL(); //set our destination URL based on source
echo $this->endURL . "<br />";

return header('Location:' . $this->endURL); //redirect 
}

private function Gate_sourceURL() {
//TODO: Fix the $_SERVER['HTTPS'] below for https://  support. 
//if ($_SERVER['HTTPS'] == "on") {$this->sourceURL .= "s";}

$this->sourceURL .= "://";
if ($_SERVER['SERVER_PORT'] != "80") {
$this->sourceURL .= $_SERVER['SERVER_NAME'].":".$_SERVER['SERVER_PORT'].$_SERVER['REQUEST_URI'];
} 
else {
$this->sourceURL .= $_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'];
}
return $this->sourceURL;
}
}//end

It is implemented as such:

Code: [Select]
<?php
include("PotentGate.php");
$gate = new PotentGate();
$gate->Gate_getURL();  

//IGNORE
//function below will acquire get variable
//echo "You came from:" . $gate->Gate_getReferrer();

?>

This works all well and good, as far as redirection goes, but refuses to add the $Gate_sourceURL to the end url.
I am left with a url like: http://blah.com/blah/misc2.php?r=
and what I am trying to achieve is that it assign $Gate_sourceURL to r (so I can use the source url as a value later on), as opposed to be being blank.
ex.
http://blah.com/blah/misc2.php?r=http://blah.com/blah/misc1.php

Any Ideas?

I set up e-commence system for our company, there is a problem in this project. When I try to add the product in the cart, it can not do the Extended Price over one thousand dollars. If the Extended Price is lower than one thousand dollars, it is working. I do not know how to fix this problem . Please tell me , thank you very much

I'm coding a google map script in php/javascript, and I'm having a hell of a time with the address.  It seems to not like any spaces for what I can tell (and I'm no php programmer).
Code: [Select]
/* Create an array of address values */
addresses = [
<?php    
   for($i=0; $i < count($dataArray); $i++) {
      $p = $dataArray[$i];
      $p = explode(":", $p);
      $addr = $p[4]; 
      echo "$addr,\n";
   }
?>                       
];
Here is data file (just one line for testing):
1315414069:41.100908:-81.442699:33:150 North Ave Tallmadge OH:1

Here is "view source" from browser:
      /* Create an array of address values */
       addresses = [
              150 North Ave Tallmadge OH,
                       
   ];       
 
I'm stumped    The map will not display with this.  If I change the $addr to another variable in the array, it works fine.
Trying to put the address in an info window on the map.

TIA,

Roots

Firstly, here's the code i'm having trouble with:

'products.php':
Code: [Select]
<?php

class product{

public $id,$brand,$partnumber,$price,$per;

  public function dump(){
    echo "dump";
    echo "<table><tr><td>$id</td><td>$brand</td><td>$partnumber</td><td>$price</td><td>$per</td></tr></table>";
  }

  public function search($strSearch){
  include ("db.php");
  $query = "SELECT * FROM products WHERE partnumber=\"$strSearch\";";
  
  $db_conn = mysql_connect($dbserver,$user,$pass);
  @mysql_select_db($database) or die("unable to connect to database");

  $result = mysql_query($query);
  $num_rows = mysql_num_rows($result);

    if($num_rows==1){
      while ($row = mysql_fetch_assoc($result)) {
        $id         = $row["id"];
        $brand      = $row["brand"];
        $partnumber = $row["partnumber"];
        $price      = $row["price"];
        $per        = $row["per"];
//DEBUG #1:  echo "<table><tr><td>$id</td><td>$brand</td><td>$partnumber</td><td>$price</td><td>$per</td></tr></table>";        
        
      }
    }

    if($num_rows>1){
      // code selection (disambiguation) here

    }

    if($num_rows<1){
      // code secondary searchs here

    }

  }

}


?>
findprod.php:
Code: [Select]
<body>
  <form action="findprod.php" method="GET">
    <input type="text" name="searchstr">
    <input type="submit" value="Search">
  </form>
</body>

<?php

if(isset($_GET['searchstr'])){
  $searchStr = $_GET['searchstr'];
  include ("products.php");

  $np = new product();
  $np->search($searchStr);
  $np->dump();
  echo $np->brand;
  
}

?>
Here's my problem:  after typing in a part-number to search for, I'm initializing a new 'product' class, and searching for that partnumber.  I know that the query is returning 1 record just like it should.  The 'DEBUG#1' line that echo's the table works just fine.  The problem is, when I try to call the 'dump' method (from 'findprod.php') the variables are empty.  Same thing if I try to access the variables directly. 

Am I doing something wrong? 
Perhaps I don't understand classes in PHP correctly, but it's almost as if the methods in the 'product' class aren't sharing the variables between each other.

Can anyone show me what I can do to make this work?

BTW: I have google'd everything I could think of for the past few days, but I just can't seem to find anything to solve this problem on my own.  I've thought of possibly using SESSION variables to accomplish this task, but I'd rather not.  I'm also just really curious to know why this isn't working.

I need to see if someone can point out something that I have missed or maybe even point me in the right direction on something.  I have a PHP script that I have run into a problem on.  The basic idea of the script is that it will send out HTML formatted emails to users of my web site.  The problem I am running into is storing the HTML content in memory so I can do a str_replace() looking for certain markers in the HTML and replace them with lets say the users name and custom links that pertain to the particular user that the email is going to.  Currently the HTML is being stored in a MySQL database, but I have already tried reading it from a flat file.  Each time I only get the first 1024 characters returned.  The problem seems to be that I am running into a PHP STRING limitation.  From the reading that I have done on the subject, the limit should be 1024 characters PER LINE with the variable able to hold somewhere around 8MB worth of data.  I can tell you that it does not matter how many \n I put into the HTML I still only get the first 1024 characters.  Is there a way I can get the entire HTML file (about 12k characters) in memory so I can work with it and hand it off to the mail function?

Thanks,

hi, i try to following codes from mysql "id" value to  "aitlik" session variable but  giving following error .   Notice: Undefined variable: row_kategori_cek in /Library/WebServer/Documents/test/cat_menu.php on line 5    

 <?php 
 // this sets variables in the session 
$_SESSION['aitlik'] = $row_kategori_cek['id'];


 echo $_SESSION['aitlik']; 
 ?> 

I'm using Session variables for the first time on a site I'm developing. I had it working fine while I was doing some admin and testing in subfolders. But the problem is I'm losing the session variables when I load the page from www.example.com, but it works from www.example.com/index.php. I would be happy to post some code if needed.

What im trying to do is have the webpage forward the user to another page after they fill out something for a certain element in the database.

But the once I put the variable into a header for forwarding, the variable is thought to be a string instead of outputting its value it holds.

Heres my code....

$variable = "nextPage";

header('Location:webpage.php?id=$variable');


But whats its doing is sending the user to the url "webpage.php?id=$variable" instead of "webpage.php?id=nextPage"

What can I do to get the header to read the variable value and not the variable name?

All help is greatly appreciated!!!

I can't get the value of $edit_proj_name and $edit_content fromn the below code.



Code: [Select]
<?php

if(isset($id))
{

$edit_proj_id = $_GET['id'];

$edit_query = "Select proj_name, content from rec_proj where proj_id = {$edit_proj_id}";

$edit_result = mysql_query($edit_query, $connection);

$edit_proj_name = mysql_result($edit_result,$i,"proj_name");
$edit_content = mysql_result($edit_result,$i,"content");



}


?>

I wonder what the problem is..

Hi Guys,        Here is the code, once logged in using known credentials it should display the content "welcome..." but it doesn't, instead it is showing "you are not authorized..." as if the session['username']); isn't being taken?

I can create the list of correct folders for the user and location, but when I click the folder name to drill down to the indvidual images I receive the following error:

Quote

Warning: DOMDocument::load() [domdocument.load]: I/O warning : failed to load external entity "/homepages/2/d333603417/htdocs/development/UploadedFiles/files.xml" in /homepages/2/d333603417/htdocs/development/imagefolders.php on line 17

Warning: Invalid argument supplied for foreach() in /homepages/2/d333603417/htdocs/development/imagefolders.php on line 54


Line 17 is this line:  Quote

$descriptions->load($absGalleryPath . 'files.xml')

and line 54 is: Quote

foreach ($items as $key => $value) {


I know that in their own right, the piece of code which loads 'files.xml' and the code which loads the folders and images work, but it's combining them that creates the issue.

I've done some research online, and I think the issue is to do with 'Session' variables and the 'foreach' array, but I'm not sure how to solve the problem.

I just wondered whether someone could perhaps have a look at this please and let me know where I'm going wrong.

Many thanks and regards
