Can't get advanced search dropdown values to fill via PHP
I have an advanced form that looks like this:
I am using a template from Bootsnipp which contains my code, and am trying to adjust it - available here.
My method of doing search is to append values to specific URL parameters based on the search, and then further down in the PHP code, check if those parameters are blank or contain values, and then execute code which fetches auctions from a database.
Since I started playing around to do this, the "Filter By State" buttons are not filling in the states filters from the database (the only thing that appears is the blank option), and also my search buttons (with the eyeglass icons) have disappeared. No idea why as this was working before. Note I am using PDO. Here is HTML and PHP code for the filter section:
<!-- Page Content -->
<div class="container">
<!--This is the search bar-->
<div class="container">
<div class="row">
<div class="col-sm-12">

<!--If this is a form it messes up the styling-->
<div method="get" class="input-group" id="adv-search" action="listings.php">
<input type="text" name="q" class="form-control"
placeholder="Search for auctions by name or description" value=""/>

Your while loop fills a $row variable
<?php while ($row = $statq->fetch()): ?>
But you are using $r to read it:
$r['state']

我已经弄明白了。这与我改变我的SQL语句并将新的SQL语句重新分配给新查询有关。另外，我不需要引用我的数据库名称，只需要引用数据库中的表。
现在可以使用：
