<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']) && $_POST['field'] === 'category2') ? 'selected="selected"': ''; ?>>category2</option>
</Select>
<input type="submit" name="search" value="Search" />
</form>
<?php
if(!empty($_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 $output;
}
?>
Question:
How could I make category2 to be the default value for the select box instead of category1? I tried this:
<Option VALUE="category2" <?php
echo (isset($_POST['field']) && $_POST['field'] === 'category2') ? 'selected="selected"' : '';
?> selected = "selected">category2</option>
but it breaks my function. When I input 1
and select category1
, after I clicked search, the select box changed to category2
. That is not what I want. I want this function to perform like this:
- Remember the values that user make for input field and select box.
- Set the default value
category2
for the select box.
How could I achieve this?
