How remove extra spaces at beginning of PHP update form to MySql database

When my PHP form page is launched, an extra white space appears at the beginning of each value from the database (and the database does not contain the extra white space). If I update the form without any change, then the white space in added to the field in the database.

In following updates, the extra space keeps on accumulating so that one white space becomes two white space, etc.

Example
(whitespace) Name <----- is displayed in the PHP update form with Name from the database (No white space is in the database)
then if I update (whether making a change or not)
(whitespace)(whitespace)  Name <----- is displayed in the PHP update form with Name from the database (and the two white white spaces are in the database)

It seems that the white spaces are produced in the PHP or HTML and, of course, inserted into the database so that on several updates display several white spaces before the value Name

How do I remove these white spaces from appearing in the form and sending to the database?
Working code can be viewed below. A solution using my code would be appreciated. Thanks.
html

<tr>
<td>First Name</td>
<td><input type="text" name="first_name" maxlength="50" value="
<?
if(trim($form->value("first_name")) == ""){
   echo $session->userinfo['first_name'];
}else{
   echo $form->value("first_name");
}
?>">
</td>
<td><? echo $form->error("first_name"); ?></td>
</tr>

php

 function updateUserField($username, $field, $value){
      $q = "UPDATE ".TBL_USERS." SET ".$field." = '$value' WHERE username = '$username'";
      return mysql_query($q, $this->connection);
   }

and

function setValue($field, $value){
      $this->values[$field] = $value;
	 }
....
   
   function value($field){
	  if(array_key_exists($field,$this->values)){
         return htmlspecialchars(stripslashes($this->values[$field]));
      }else{
         return "";
      }
   }

First I suggest to not use short php tags: use <?php instead.

Second I would suggest to use this:

<tr>
<td>First Name</td>
<?php
if(trim($form->value("first_name")) == ""){
?>
<td><input type="text" name="first_name" maxlength="50" value="<?php echo $session->userinfo['first_name'];
 ?>"></td>
<?php
}else{
?>
<td><input type="text" name="first_name" maxlength="50" value="<?php  echo $form->value("first_name"); ?>"></td>
<?php
}
?>
<td><? echo $form->error("first_name"); ?></td>
</tr>

Hi,

Why don't you trim returned value before saving into the database, the code will be much simpler:

<tr>
<td>First Name</td>
<td><input type="text" name="first_name" maxlength="50" value="
<?
if(trim($form->value("first_name")) == ""){
   $tmpvalue = trim($session->userinfo['first_name']);
   echo $tmpvalue;
}else{
   $tmpvalue = trim($form->value("first_name"));
   echo $tmpvalue;
}
?>">
</td>
<td><? echo $form->error("first_name"); ?></td>
</tr>

Your solution worked perfectly to trim the white spaces both on the form display and on database update.

Thanks.
