I have a problem with creating an script which will fill one
combobox on base of what is selected in the other
I am newbie in the field of PHP / JS so please be patient with me. Here it is what I have done so far:
js script which is on click event
Base combobox filled with values from database:
<select id="dropdown" name="dropdown" onchange="selectDropdown()"> <option value="dd">--take an option--</option> <? $standard = Env::value('standard'); if (!$status) $statement = "select code from standard"; foreach ($db->query($statement )->fetchall() as $row) echo "<option".($row == $standard ? ' selected ' : '').">$row</option>"; ?> </select>
and now I want to put the selected option into other combobox - actually I will execute another SQL query with the value chosen previously but the fact that I will have value in variable is more then enough for me to finish the task.
<select name='st' class='txt'> <option value="st"><? echo $field; ?></option> </select>
Posted code is created based on one of the articles I found, I have remake it according to my needs but this does not work. Could anyone point me where I am doing mistake?
