我正在努力使用以下 PHP 和 JavaScript 代码来让 2 组复选框过滤从 MySQL 数据库获得的一系列数据。
这是代码：
<script type="text/javascript">
//http://jsbin.com/ujuse/1/edit
$(function() {
$("input[type='checkbox']").on('change', function() {
var boxes = [];
// You could save a little time and space by doing this:
var name = this.name;
// critical change on next line
$("input[type='checkbox'][name='"+this.name+"']:checked").each(function() {
boxes.push(this.value);
});
if (boxes.length) {
$(".loadingItems").fadeIn(300);
// Change the name here as well
$(".indexMain").load('indexMain.php?'+this.name+'=' + boxes.join("+"),
function() {
$(".indexMain").fadeIn('slow');
$(".loadingItems").fadeOut(300);
});
} else {
$(".loadingItems").fadeIn(300);
$(".indexMain").load('indexMain.php', function() {
$(".indexMain").fadeIn('slow');
$(".loadingItems").fadeOut(300);
});
}
});
});
</script>
<?php
function echoCheckboxSet($header, $divClass, $columnName, $setName) {
include ("connection.php");
$checkboxes = $con -> prepare("SELECT DISTINCT $columnName FROM item_descr ORDER BY $columnName ASC");
$checkboxes->execute();
?>
<div class="bgFilterTitles">
<h1 class="filterTitles"><?php echo $header;?></h1>
</div>
<div class="<?php echo $divClass; ?>">
<?php
while ($box = $checkboxes->fetch(PDO::FETCH_ASSOC)):
$boxColumnName = str_replace('_',' ',$box[$columnName]);
?>
<input type='checkbox' class='regularCheckbox' name='<?php echo $setName; ?>' value='<?php echo $box[$columnName]; ?>' />
<font class='similarItemsText'><?php echo $boxColumnName; ?></font>
<br />
<?php
endwhile;
?>
</div>
<?php
} // end of echoCheckboxSet
// Call our method twice, once for colors and once for prices
echoCheckBoxSet("COLOR", "colors", "color_base1", "color[]");
echoCheckBoxSet("PRICE", "prices", "price", "price[]");
?>
然后我完美地得到了我的复选框，但是当点击它们中的任何一个时，它们什么都不做。
我indexMain.php检索这样的值：
$colors = $_GET['color[]'];
echo "TEST".$colors[1];
$colors = explode(' ', $colors);
$parameters = join(', ', array_fill(0, count($colors), '?'));
$items = $con -> prepare("SELECT * FROM item_descr WHERE color_base1 IN ({$parameters})");
$items ->execute($colors);
$count = $items -> rowCount();
----------------- 添加回声：
echo "<div>Showing ".$count."items</div>";
while($info = $items->fetch(PDO::FETCH_ASSOC))
{
echo "<div name='item' id='".$info['color_base1']."' class='itemBox'><div class='showItem'><a href='items_descr.php?itemId=".$info[id_item]."'><img class='itemImage' alt='' src='images/$info[imageMid].jpg'></img></div><br />";
echo "<div class='indexItemText'><font class='similarItemsText'><a href='items_descr.php?itemId=".$info[id_item]."'>".$info[name]."</a><font class='price'> - $".$info[price]."</div></div>";
$row_count++;
if ($row_count % 2 == 0)
{
echo "<br />"; // close the row if we're on an even record
}
}
知道会发生什么吗？
