how to let the form remember the values i put

 <form name="search" method="post" >
 Seach for: <input type="text" name="find" /> in
 <Select NAME="field">
 <Option VALUE="category1">category1</option>
 <Option VALUE="category2">category2</option>
 </Select>
 <input type="submit" name="search" value="Search" />
 </form>

<?php
    if(!empty($_POST)){
        $options = array('category1'=> array('1' => 'dog', '2' => 'cat'), 'category2' =>array('1'=>'flower', '2'=>'grass'));
        $input = trim($_POST['find']);
        $category = $_POST['field'];
        $output = $options[$category][$input];
        echo $output;
}
?>

Question:

if i input 1 and select 'category2', it shows:flower, but the input filed became empty, and select box went back to 'category1', is there a way that i can let input box and select box keep the value i put there, in my case, after i click submit botton, '1' still is in input field, and 'category2' shows in select box.

Use value="<?php if(isset($_POST[])) echo $_POST[]; ?>"

<form name="search" method="post" >
 Seach for: <input type="text" name="find" value="<?php echo (isset($_POST['find']) ? $_POST['find'] : ''); ?>" /> in
 <Select NAME="field">
 <Option VALUE="category1" <?php echo (isset($_POST['field']) && $_POST['field'] === 'category1') ? 'selected="selected"': ''; ?>>category1</option>
 <Option VALUE="category2" <?php echo (isset($_POST['field']) && $_POST['field'] === 'category2') ? 'selected="selected"': ''; ?>>category2</option>
 </Select>
 <input type="submit" name="search" value="Search" />
 </form>

Let's say this is your username input/form

<input type="text" name="username" value="" />

now inside where it says value="", You have to put PHP code to be remembered if someone posts something. Much like: 

<?php if(isset($_POST['username'])) echo $_POST['username']; endif ?>

which means, if a persone already submits a username, it will stay there, else, it will just be empty.

You could create a little function though, instead of putting that much of code inside,
