How to sort POST data in a sequence?

[KvickaN]

Hello guys.

 

I have a form with 20 images. My user have to write a description for each image and when submitting the form the user will get an HTML code which will display an album.

 

My problem is that my users want to choose a sequence of the images in the album. How do I solve that?

 

I tried with making a select with 20 options (number 1-20) for each image and a desription for the user to place them in a correct sequence but I don't know how to do it. And another problem is when a user chooses the same number for more than one image.

 

Thanks

Can you give an example of the code?

Thanks. Here it is:

 

// Show the images:
$i = 0;
$dir = opendir("../images");
while (($image = readdir($dir)) !== false) {
if ($image != "." && $image != "..") {
	$i++;
	image_table_row($image, $i);
}
}


// Here is the function:
function image_table_row($image, $i) {
echo "<tr>";
echo "<td style=\"width:150px;\"><img src=\"http://".$_SERVER['HTTP_HOST']."/images/".$image."\" style=\"width:100px;height:100px;\" /></td>";
echo "<td style=\"width:150px;\"><input type=\"text\" maxlength=\"65\" name=\"desc-".$i."\" /></td>";
echo "<td><select name=\"order-".$i."\" style=\"width:60px;\">
<option value=\"0\" selected=\"selected\">-</option>";
for ($i2 = 1; $i2 <= 20; $i2++) {
	echo "<option value=\"".$i2."\">".$i2."</option>";
}
echo "</select></td></tr>";
echo "<input type=\"hidden\" value=\"".$image."\" name=\"img-".$i."\" />";

}


// Code when submitting the form:
// HOW DO I GET THE SORTING CORRECT IN HERE?
if(isset($_POST['submit'])) {
$html = "";
for ($i = 1; $i <= 20; $i++) {
	if(isset($_POST["order-".$i.""]) && $_POST["order-".$i.""] > "0") {
		$html .= "\n<div class=\"image-gallery\"><a href=\"http://".$_SERVER['HTTP_HOST']."/images/".$user."/".$_POST["img-".$i.""]."\" rel=\"lightbox[1]\"";
		if($_POST["desc-".$i.""] != "") {
			$_POST["desc-".$i.""] = str_replace("<?", "<?", $_POST["desc-".$i.""]);
			$_POST["desc-".$i.""] = str_replace("?>", "?>", $_POST["desc-".$i.""]);
			$html .= " title=\"".$_POST["desc-".$i.""]."\" ";
		}
		$html .= "><img src=\"http://".$_SERVER['HTTP_HOST']."/images/".$user."/mini-".$_POST["img-".$i.""]."\" /></a>";
		if($_POST["desc-".$i.""] != "") {
			$html .= "<div>".$_POST["desc-".$i.""]."</div>";
		}
		$html .= "</div>\n";
	}
}
$html .= "\n<div style=\"clear:both;height:0;\"> </div>";
echo "<textarea style=\"width:500px;height:300px;\">".htmlspecialchars($html)."</textarea>";

}
