hello:

I'm working on this code that receives a variable via url and performs a mysql search for records using the value of the variable as the key word. I'm using the following code --which I'm currently using successfully on another section of my project, but experiencing problems in a different section.

The code is the same with a few minor changes (database and table connection etc), for some odd reason, the page comes out blank without any errors. I tried changing the connection information with intentional false access info to see if an error would be produced, still nothing. I'm a bit puzzled. Here is the code:

<html>

<head>
<meta http-equiv="Content-Language" content="en-us"> <meta http-equiv="Content-Type" content="text/html; charset=windows-1252"> <title>Content of Search Results</title> <!--<link rel="stylesheet" type="text/css" href="../music/.keycode2.css"> --></head> <body topmargin="0">

<hr color="#C0C0C0" size="1">
<table border="0" width="100%" id="resultbar" bgcolor="#E2EBED">
	<tr>
<td>Customer's Job Cost History</td>
	</tr>
</table>
<div class="graph" style="margin-left: 0px; margin-right: 0px;" display="inline">
    <align="left">
		<hr size="1" color="#CCCCCC">

<?php

  // Get the search variable from URL
  $var = @$_GET["clientID"] ;
  $trimmed = trim($var); //trim whitespace from the stored variable

// rows to return
$limit=10; 

// check for an empty string and display a message.
if ($trimmed == "")
  {
  //echo "<p>Please enter a search...</p>";
  exit;
  }

// check for a search parameter
if (!isset($var))
  {
  echo "<p>We dont seem to have a search parameter!</p>";
  exit;
  }
//connect to your database

$query = "select * from billofservice where vehicleid  like '%$trimmed%' order by vehicleid ";

 $results=mysql_query($query);
 $numrows=mysql_num_rows($results);
  
if ($numrows == 0)
  {

  echo "<p>Sorry, your search for <a href=\"http://xxxxxxxxxxxxxxxxxxxxx/newsounds.php\?q=$var\">&quot;" . $trimmed . "&quot;</a> in the music category returned zero results</p>";

  }

// next determine if s has been passed to script, if not use 0
  if (empty($s)) {
  $s=0;
  }

// get results
//else{
  $query .= " limit $s,$limit";
  $result = mysql_query($query) or die("Couldn't execute query");

  }

// calculate number of pages needing links
  $pages=intval($numrows/$limit);

// $pages now contains int of pages needed unless there is a remainder from division

  if ($numrows%$limit) {
  // has remainder so add one page
  $pages++;
  }

// check to see if last page
  if (!((($s+$limit)/$limit)==$pages) && $pages!=1) {

  // not last page so give NEXT link
  $news=$s+$limit;

  echo "&nbsp;<a href=\"$PHP_SELF?s=$news&q=$var\">Next 10 &gt;&gt;</a>";
  }

$a = $s + ($limit) ;
  if ($a > $numrows) { $a = $numrows ; }
  $b = $s + 1 ;
  echo "<p>-----------------------------Showing results $b to $a of $numrows---------------------------</p>";
  ?>
	
		</body></p></td>
		</tr>
	</div>	

&nbsp;</html>

for the referring url variable I have something like this:

onclick=\"window.location= 'invoicehistory.php?var=$clientID'

Can someone take a look at it to see if they catch something I'm not seeing.

Thanks,
Mossa

thanks for the reply. only this is showing:

<html>

<head>
<meta http-equiv="Content-Language" content="en-us"> <meta http-equiv="Content-Type" content="text/html; charset=windows-1252"> <title>Content of Search Results</title> <!--<link rel="stylesheet" type="text/css" href="../music/.keycode2.css"> --></head> <body topmargin="0">

</table>
<div class="graph" style="margin-left: 0px; margin-right: 0px;" display="inline">
    <align="left">
		<hr size="1" color="#CCCCCC">

and if I were to remove that section, absolutely nothing is shown.

You have 2 errors in your code before the bit that doesn't process. I doubt it will fix the problem but you probably want to fix them.

Line 12:

<div class="graph" style="margin-left: 0px; margin-right: 0px;" display="inline">

Should be:

<div class="graph" style="margin-left: 0px; margin-right: 0px; display: inline;">

Line 13:

<align="left">

This isn't needed as the default alignment is the left and there is no <align> tag.

Thanks for pointing this out. I'll modify. Though I had even removed this section during debugging and still the page remained blank.

0

Which is the reason I doubted it would fix it.

Here's an obvious question I should have already asked:

Does the server you're using support PHP?

0

Nevermind that, I found your error.

Remove every instance you have of exit; .

From what I can see, that's on lines 29 and 36.

When exit; is called, it stops rendering all code after it which is why nothing is displayed.

Borzoi, you are correct! Those two instances of exit; were causing the failure.
Thank you very much

It was quite odd, because the "exit;" served the purpose of stopping the script from moving forward if the string from the url was empty, it therefor would display a message and exit the script. None was working! Commenting out both exits; did it. I went back readjusted those strings and all is well.

Best,
Mossa
