Question

There seems to be a problem with this script. Whenever I change the value of $i to like 2 or something it outputs A field not ALL fields. I am not sure what is wrong.

Additionally is it possible to do something like this? Basically there are more fields in the result query, but I only want to output the values of the fields listed in the result query that I want the user to be able to edit (displayed in resultInput)

<?php
require('dbc.php');
mysql_select_db($db);
$result = mysql_query("SELECT * FROM about WHERE id=1");
$resultInput = array('page_header', 'sub_header', 'content', 'content_short');


if (mysql_num_rows($result) > 0) {
//loop creates inputs
//make $resultInput object to array.
$i=0;
while ($row = mysql_fetch_assoc($result)) {
    $meta = mysql_fetch_field($result, $i);
    if(in_array($meta->name, $resultInput )){
    echo '<div class="wrapper"><label>' . ucfirst(str_replace('_', ' ',$meta->name)) . 
    '<br><input name="' . $meta->name . 
    '" type="text" class="input" value="'.$row[$meta->name].'"><br></label></div>';
    }
    $i++;
 }
}
?>

While this isnt how I would do it.. ive taken your code and made it so it should work..

if (mysql_num_rows($result) > 0) { 
//loop creates inputs 
//make $resultInput object to array. 

    while ($row = mysql_fetch_assoc($result)) 
    { 
        $i=0; 
        while ( $i<   mysql_num_fields($result)) 
        {
            $meta = mysql_fetch_field($result, $i); 
            if(in_array($meta->name, $resultInput ))
            { 
              echo '<div class="wrapper"><label>' . ucfirst(str_replace('_', ' ',$meta->name)) .  
             '<br><input name="' . $meta->name .  
             '" type="text" class="input" value="'.$row[$meta->name].'"><br></label></div>'; 
            } 
            $i++; 
        } 
    } 
    ?> 

FYI

Heres how I would have done it, although looking at it, Im not happy with the echo.. but..

    while ($row = mysql_fetch_assoc($result)) 
    { 
        foreach ($row as $fieldname => $value)
        {
            if (in_array($fieldname, $resultInput )) Display_data($fieldname,$value);
        } 
    } 

function Display_data($fieldname,$value)
{
              echo '<div class="wrapper"><label>' . ucfirst(str_replace('_', ' ',$fieldname)) .  
             '<br><input name="' . $fieldname .  
             '" type="text" class="input" value="'.$value.'"><br></label></div>'; 
}
