select all from database of the selected checkbox - php

Question

The code given below which display all the products in the home page.. and each product has a checkbox.. I wanted to select the checkbox of few products, and if I click on submit, the next page doesn't view the selected checkbox results
$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">
<img style=" 1px solid;" src="inventory_images/' . $id . '.jpg" alt="' . $product_name . '" width="100" height="100" border="0" /><div class="pr-info"><h4>' . $product_name . '</h4>
<input type="checkbox" name="check[]" value="<?php .$id. ?>"/>
</div>
</div></td>';
}
}
The Code below is where i used to retrieve the data from database of selected checkbox
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( );
}

Answer 1

Try changing the beginning of your second code to this:
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 = ...
But, how it was said before, you should start using PDO!

Answer 2

I think you final query and code should look this way...please change your code with this...and post the results:
foreach($_POST['check'] as $k){
$where[]= $k;}
var_dump($where); //it show you something, show me the var_dump result ???
include "storescripts/connect_to_mysql.php";
$query = "Select * from products where id IN(".implode(",",$where).")";
echo $query; //this line too....show me the result
$sql = mysql_query($query);
// Connect to the MySQL database
$productCount = mysql_num_rows($sql);
//the rest of your code ;)
-----------------------EDITED--------------------------------
Your problem is in this line:
<input type="checkbox" name="check[]" value="<?php .$id. ?>"/>
That line is wrong, make this change and see how it's work:
<input type="checkbox" name="check[]" value="<?php echo $id;?>"/>
