How to get Text Area in WordPress posts section? - php

Question

I need to change this code to implement "More info" field as a text field in my WordPress post section.
The "More info" field looks like this:
I use smartmetabox. It has 2 files:
textarea.php:
<textarea name="<?php echo $id?>" id="<?php echo $id?>" rows="5" cols="100" class="custom"><?php echo $value?></textarea>
text.php:
<input type="text" name="<?php echo $id?>" id="<?php echo $id?>" value="<?php echo $value?>" class="regular-text" />
And my_file.php code is:
<?php
add_action( 'add_meta_boxes', 'cd_meta_box_add' );
function cd_meta_box_add()
{
add_meta_box( 'my-meta-box-id', __('Information', 'addict'), 'cd_meta_box_cb', 'post', 'normal', 'high' );
}
function cd_meta_box_cb( $post )
{
$values = get_post_custom( $post->ID );
$creteria_1_text = isset( $values['creteria_1_text'] ) ? esc_attr( $values['creteria_1_text'][0] ) : '';
$check = isset( $values['my_meta_box_check'] ) ? esc_attr( $values['my_meta_box_check'][0] ) : '';
wp_nonce_field( 'my_meta_box_nonce', 'meta_box_nonce' );
?>
<p>
<label for="creteria_1_text"><b><?php _e("More info, 'addict') ?></b></label>
<input style="width:85%" type="text" name="creteria_1_text" id="creteria_1_text" value="<?php echo $creteria_1_text; ?>" />
</p>
<?php
}
add_action( 'save_post', 'cd_meta_box_save' );
function cd_meta_box_save( $post_id )
{
// Bail if we're doing an auto save
if( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) return;
// if our nonce isn't there, or we can't verify it, bail
if( !isset( $_POST['meta_box_nonce'] ) || !wp_verify_nonce( $_POST['meta_box_nonce'], 'my_meta_box_nonce' ) ) return;
// if our current user can't edit this post, bail
if( !current_user_can( 'edit_post' ) ) return;
// now we can actually save the data
$allowed = array(
'a' => array( // on allow a tags
'href' => array() // and those anchords can only have href attribute
)
);
// Probably a good idea to make sure your data is set
if( isset( $_POST['creteria_1_text'] ) )
update_post_meta( $post_id, 'creteria_1_text', wp_kses( $_POST['creteria_1_text'], $allowed ) );
}
// function for show rating content
//$key_1_value = get_post_meta($post->ID, 'my_meta_box_text', true);
?>

After some digging i found that i should replace this code:
<input style="width:85%" type="text" name="creteria_1_text" id="creteria_1_text" value="<?php echo $creteria_1_text; ?>
To:
<textarea name="creteria_1_text" id="creteria_1_text" rows="5" cols="100" class="custom"><?php echo $creteria_1_text; ?></textarea>
