PHP - If Database Field Is Empty, How To Show On Form "empty"

Hi,
I need to call to this text to add a all with value "blank/empty" or "0" to the dropdownlist code below..
it should be inserted int the first position in the dropdownlist and have a value blank and call to this text from the language files:            
            $searchAll = gettext('_LANGUAGE_SEARCH_ALL',_LANGUAGE_SEARCH_ALL,false,false);
            example is:
            ratestitle=>0 gettext('_LANGUAGE_SEARCH_ALL',_LANGUAGE_SEARCH_ALL,false,false);
            the words it calls is "ALL" when the user selects or leaves the "ALL" in the list the value
             remains empty this allows the search to search everything..
basically im stuck how to get it in the dropdown list as the first default position:
can anyone help?

here is my code://this is a search function which calls to the field rate_title the text from the select box is matched to the database table and the search pages shows the search option is the search is successful.. I have 5 of these types of searches but cant give a broader search option to my users as the values must be selected to search--- i need the option "ALL" to have a "EMPTY" value or no value....
         

if (in_array("ratestitle",$searchOptions)&& $showSearchOptions )
            {
            if (empty($sch->filter['ratestitle']) )
               $selectOption=$output['LANGUAGE_SEARCH_RATESTITLE'];
            else
               $selectOption=$sch->filter['ratestitle'];
            $showButton=true;            
         $query = "SELECT DISTINCT rate_title FROM #__rates_table ORDER BY rate_title ASC";
         $dropDownList ="<select class=\"inputbox\" name=\"ratestitle\">";
         $ratesitles =doSelectSql($query);         
         foreach ($ratesitles as $ratetitle)
            {
            $selected="";
            $rate_title=$ratetitle->rate_title;
            if ($ratetitle==".$sch->filter['ratestitle'].")
               $selected="selected";
            $dropDownList .= "<option ".$selected." value=\"".$rate_title."\">".$rate_title."</option>";
            }
         $dropDownList.="</select>";
         $output['RATESTITLE']=$dropDownList;
            }
               

Hello Everyone,

I am having issues where people are submitting null characters on my website (I.e. %00).  Currently, I check if their is a value by using the empty function, and I also am checking if the value after running the trim command is =="".  How can I check for these special characters to make sure that whatever they are submitting actually contains some sort of legitimate value?

Thanks!

Can someone please help me with an array problem i can not figure out.

I need the array to be numbered from 1 to how ever many fields that are needed in the form and have a mysql field name and the title of the field also in the array.

1, "mysql_field_name", "Title of form field"
2, "", ""

and so on

then the form will be shown based on the array.

I have the following draft code which I am working with.

any suggestions on how i may do this array ?

Code: [Select]
<?php
$options = array(
'1'=> array('fieldtext'=>'option1', 'mysqlfield'=>'option1'),
'2'=> array('fieldtext'=>'option2', 'mysqlfield'=>'option2'),
'3'=> array('fieldtext'=>'option3', 'mysqlfield'=>'option3'),
'4'=> array('fieldtext'=>'option4', 'mysqlfield'=>'option4'),
);


// $options = array(1 => "option1", "option2", "option3", "option4");

// the line above works but i want to include the name of the mysql field as well.

$userid = 1;

?>
<div style="align: center; margin: 12px; font-family:Tahoma;">
<br><br><?php
if ($_POST['Update'] != "Update") { // check if form submitted yet, if not get data from mysql.
$res = db_query("SELECT * FROM `users` WHERE `userid` = '" . $userid . "'");
foreach($options as $key => $value) { $_POST[$key] = mysql_result($res, 0, $value); }
$ok_to_update = "no";
} elseif ($_POST['Update'] == "Update") { // check if form submitted yet, if so get POST data.
// error checking
// foreach($options as $key => $value) {
// $_POST[$i] = "";
// }
$ok_to_update = "yes";
}

if ($_POST['Update'] == "Update" && $ok_to_update == "yes") {
// $res = db_query("INSERT INTO `users` () VALUES ()"); // add user details to database.
?><p><br><br><br>Thank you for updating</p><?php
} else {
?><form name="form1" method="post" action="">
<?php foreach($options as $key => $value) {
?><p><?php echo($value); ?>:&nbsp;<input type="text" name="<?php echo($key); ?>" value="<?php echo($_POST[$key]);?>"></p>
<?php } ?>
<input name="Update" type="submit" value="Update">
</form>
<?php } ?>
</div>
