Dynamically filled form inserts space at beginning of the field.

Question

Hi guys,

I have a form where users update a posts information.

One of the sections is the following :

<td><input type="text" name="author" size="30" value="<?php poem_info($pid,author); ?>"></td>

as you can see I'm using php to populate the field. Here is the function poem_info():

function poem_info($pid,$record){
		require_once '../classes.db_connect.php';
		$db = new Database;
		
		$query = 'SELECT '.$record.' FROM poems WHERE id = "'.$pid.'"';
		$db->query($query);
		
		$db->singleRecord();    // retrieve a single record
		echo $db->Record[$record];
	}

The problem I am having is that if I edit the information in the form and save it to the database it saves perfectly. If I check the database it's saved with no spaces before the user input.

But when I enter the form to edit the information a space is inserted and I can't figure out why. I have tried to use trim() but it's still not working and it's driving me mad. I know it's not the DB because when I log in and check it manually it's fine. So I must be doing something wrong somewhere else and it's killing me! Please help!

value="<?php poem_info($pid,author); ?>" //TO
value="<?php poem_info($pid,'author'); ?>"

AND

$query = 'SELECT '.$record.' FROM poems WHERE id = "'.$pid.'"'; //TO
$query = "SELECT '$record' FROM poems WHERE id = $pid";

Any better?

BTW what DB class you using? Is the db->Record[$record] correct? The function appears a little wasteful with regard including the class. As a rule the db connection vars can be called at the head of the page (or include) and be used throughout - no need to re-instantiate.

Hey ardav thanks for the reply. I tired what you said above and it didn't work out, have you got any other idea's?

Here's my mysql class i'm using:

<?
class Database
    {
    var $Host     = ""; // Hostname of our MySQL server.
    var $Database = ""; // Logical database name on that server.
    var $User     = ""; // User and Password for login.
    var $Password = "";
    
    var $Link_ID  = 0;  // Result of mysql_connect().
    var $Query_ID = 0;  // Result of most recent mysql_query().
    var $Record   = array();  // current mysql_fetch_array()-result.
    var $Row;           // current row number.
    var $LoginError = "";
	
	var $sanatized;		//sanatized entry

    var $Errno    = 0;  // error state of query...
    var $Error    = "";
	
	/*------------------------------------------------------------
	                       Example Usage
	--------------------------------------------------------------
	include ('db_connect.php');
	
	$db = new Database;
	
	// do a query to retrieve a single record
	$query = "SELECT * FROM members LIMIT 1";
	$db->query($query);        // query the database
	$db->singleRecord();    // retrieve a single record
	echo $db->Record['username'].'<br>';        // output a field value from the recordset

	// do a query to retrieve multiple records
	$query = "SELECT * FROM members";
	$db->query($query);        // query the database
	while ($db->nextRecord())
	{
	echo $db->Record['username']."<br>";        // output a field value from the recordset
	} // end while loop going through whole recordset

	// do a query to count number of rows
	$query = "SELECT * FROM members";
	$db->query($query);
	echo $db->numRows();
