下面给出的代码显示主页中的所有产品..每个产品都有一个复选框..我想选择几个产品的复选框，如果我点击提交，下一页不会显示选中的复选框结果
$sql = mysql_query("SELECT * FROM products ORDER BY date_added DESC LIMIT 15");
$productCount = mysql_num_rows($sql); // count the output amount
if ($productCount > 0) {
$colindex = 1;
$totcols = 3;
$rowclosed = false;
//$totrows=ceil($count/$totcols);
$dynamicList .= "<dl id='Searchresult'> <form action='selected.php' method='POST'> <table width=\"50%\" border=\"0\" cellspacing=\"0\" align=\"center\" cellpadding=\"3\">";
while ($row = mysql_fetch_array($sql)) {
$id = $row["id"];
$product_name = $row["product_name"];
$price = $row["price"];
$date_added = strftime("%b %d, %Y", strtotime($row["date_added"]));
if ($colindex == 1) {
$dynamicList .= "<tr>";
$rowclosed = false;
}
$dynamicList .= '<td width="142" valign="top" align="center">
<div id="products">
<div class="product">
<a href="product.php?id=' . $id . '"> <img style=" 1px solid;" src="inventory_images/' . $id . '.jpg" alt="' . $product_name . '" width="100" height="100" border="0" /></a><div class="pr-info"><h4>' . $product_name . '</h4>
<input type="checkbox" name="check[]" value="<?php .$id. ?>"/>
</div>
</div></td>';
}
}
下面的代码是我用来从选定复选框的数据库中检索数据的地方
foreach ($_POST['check'] as $k => $check) {
$where[ ] = $k . " = '" . mysql_real_escape_string($check) . "'";
}
include "storescripts/connect_to_mysql.php";
$sql = mysql_query("Select * from products where " . implode(' AND ', $where)); // Connect to the MySQL database
$productCount = mysql_num_rows($sql); // count the output amount
if ($productCount > 0) {
while ($row = mysql_fetch_array($sql)) {
$id = $row["id"];
$product_name = $row["product_name"];
$price = $row["price"];
$details = $row["details"];
$date_added = strftime("%b %d, %Y", strtotime($row["date_added"]));
$dynamicList .= '<td width="142" valign="top" align="center">
<div id="products">
<div class="product">
<a href="printer.php?id=' . $id . '">
<img style=" 1px solid;" src="inventory_images/' . $id . '.jpg" alt="' . $product_name . '" width="200" height="200" border="0" />
</a>
<div class="pr-info"><h4>' . $product_name . '</h4><p>' . $details . ' </p>
<span class="pr-price"><span>Rs.</span><sup>' . $price . '</sup></span>
</div>
</div></td>';
}
} else {
echo "That item does not exist.";
exit( );
}
最佳答案
尝试将第二个代码的开头更改为:
include "storescripts/connect_to_mysql.php";
$sql = mysql_query('SELECT * FROM products WHERE id IN ('.implode(', ', array_values($_POST['check'])).')');
// rest of your code, beginning at $productCount = ...
但是，之前怎么说，你应该开始使用PDO !
