I'm *this* close to having a chained select running but for some reason it doesn't seem to be picking up a variable.
Code: <?php
require ('inc/connection.php');
//seeming that we are just submitting and refreshing to the one page we need to check if the post variable is set, and if so a couple of other variables are set if(!isset($_POST['state'])) { $next_dropdown = 0; } else { //When set this variable reveals the next drop down menu $next_dropdown = 1; //this variable keeps the previous selection selected $selected = $_POST['state']; } ?>
<form name="form" method="post" action=""> <select name="state" style="font-size:20px;"> <option value="NULL">State</option> <?php $query = "SELECT id, name FROM state ORDER BY name ASC"; $result = mysql_query($query); while($row = mysql_fetch_array($result)) {?> <option value="<?php echo $row[0]; ?>" onClick="document.form.submit()" <?php if(isset($selected) && $row[0] == $selected) {echo "selected='selected'";} ?>><?php echo $row[1]; ?></option>n"; <?php } echo '</form>n'; //this is where the other form will appear if the previous form is submitted if($next_dropdown == 1) {?> <form name="form2" action="" method="post"> <select name="city"> <option value="NULL">City</option> <?php $query2 = "SELECT * FROM city WHERE state_id = " . $row[0]; $result2 = mysql_query($query2); while($row2 = mysql_fetch_array($result2)) { ?> <option value="<?php echo $row2[0]; ?>" onClick="document.form2.submit()"><?php echo $row2[1]; ?></option> <?php }?> </select> </form> <?php } ?>
The state drop down works fine. Once a state is selected, it will display the city drop down. However, the city drop down never populates. It's as though it forgets what $row[0] is. Any thoughts?
