Hi,
With your help I got some checkboxes generated the other day for a form.
I would like some help getting a similar problem solved.
I am now making a form to edit db entries made in the previous form. I
have three tables involved: art, media and media_art. I need to show
checkboxes for all available media. For the chosen record ($cartoon,
which equals an art_id selected by the user) I must also go into the
media_art table, and where the selected art ID has a corresponding
media_id, display that media_id's media_name as a checked box.
TABLE media:
media_id media_name
1 ink
2 pencil
3 watercolor
4 gauche
5 watercolor pencil
To find out the art_id of the chosen record, the user is selecting from
a dropdown box in the form. I'm doing queries like this to make a
publisher dropdown in a similar vein:
$query = "SELECT * FROM art WHERE art.art_id = '$cartoon'";
$publisher_query = 'SELECT * FROM publisher';
$result = mysql_query($query);
$publisher_result = mysql_query($publisher_query);
while ($rows = mysql_fetch_assoc($result)){
$publisher_dropdown = '<select name="publisher_id">';
while ($pub = mysql_fetch_assoc($publisher_result)){
$publisher_dropdown .= '<option value="' . $pub['publisher_id'];
if ($pub['publisher_id'] == $rows['publisher_id']){
$publisher_dropdown .= '" selected ';
}
$publisher_dropdown .= '">' . htmlentities($pub['publisher_name']);
}
$publisher_dropdown .= '</select>';
}
I now need to formulate how to make the checkboxes similarly. The
original setup to make the checkboxes was :
$media_query = 'SELECT media_id,media_name FROM media GROUP BY media_name';
$media_result = mysql_query($media_query);
$checkbox_media = array ();
$media_types = array();
while ($media_rows = mysql_fetch_assoc($media_result)){
$checkbox_media[] = "<input type='checkbox' name='media_types[]'
value='{$media_rows['media_id']}' />{$media_rows['media_name']} ";
}
Those which were checked were inserted into media_art thusly:
media_id art_id
3 1
4 1
5 1
What I want to do is say "For every media_id which is associated with
$cartoon in the table media_art, check the box; for all others leave
them unchecked.
How can I do this?
Thanks very much in advance,
Jack
