form problem

[snaack]

Hi!

I've got a problem with a HTML-form. My script dynamically generates form-elements (checkboxes). The name of the checkboxes are all the same.

How can I request all the checkboxes that have been sent?

sample code:

	while ($x < $i)
	{
		$iUserID = $objAuthMatrix[$x][$j-2];
		$iUserName = $objAuthMatrix[$x][$j-1];
		$sTable .= "\t<tr>\n\t\t<td>User: ".$iUserName."</td>\n";
		while ($y < $j-2)
		{
			$iSiteID = $objRsSites[$y][0];
			if ($objAuthMatrix[$x][$y] == 1)
				$sTmp = "<input type=\"checkbox\" name=\"userSiteID\" value=\"{$iUserID}_{$iSiteID}\" checked />";
			else
				$sTmp = "<input type=\"checkbox\" name=\"userSiteID\" value=\"{$iUserID}_{$iSiteID}\" />";

		$sTable .= "\t\t<td>".$sTmp."</td>\n";
		$y++;
	}
	$sTable .= "\t</tr>\n";
	$y = 0; //$y 
	$x++;
}

sample form: (generated by the script)

<form action="admin_user.php" method="post"><!-- start generated table -->
<table>
	<tr>
		<td>User: albron</td>
		<td><input type="checkbox" name="userSiteID" value="4_1" /></td>
		<td><input type="checkbox" name="userSiteID" value="4_2" /></td>
		<td><input type="checkbox" name="userSiteID" value="4_3" checked /></td>
	</tr>
	<tr>
		<td>User: jack</td>
		<td><input type="checkbox" name="userSiteID" value="3_1" /></td>
		<td><input type="checkbox" name="userSiteID" value="3_2" checked /></td>
		<td><input type="checkbox" name="userSiteID" value="3_3" /></td>
	</tr>
	<tr>
		<td>User: nico</td>
		<td><input type="checkbox" name="userSiteID" value="1_1" checked /></td>
		<td><input type="checkbox" name="userSiteID" value="1_2" checked /></td>
		<td><input type="checkbox" name="userSiteID" value="1_3" /></td>
	</tr>
	<tr>
		<td>User: peter</td>
		<td><input type="checkbox" name="userSiteID" value="2_1" checked /></td>
		<td><input type="checkbox" name="userSiteID" value="2_2" /></td>
		<td><input type="checkbox" name="userSiteID" value="2_3" /></td>
	</tr>
</table>
<!-- end generated table -->
<input type=submit>
</form>

So, all the checkboxes are named userSiteID with value userID_siteID

I want to request all the posted values for userSiteID but $_REQUEST['userSiteID'] only contains 1 value, the last posted checkbox!

What the hell am I doing wrong??

	<td><input type="checkbox" name="userSiteID[0]" value="1_1" checked /></td>
	<td><input type="checkbox" name="userSiteID[1]" value="1_2" checked /></td>
	<td><input type="checkbox" name="userSiteID[2]" value="1_3" /></td>

can be accessed through

echo $_POST[ 'userSiteID'][0];

🙂 look closely at field names, it creates an array and voila

Hope it helps

ahhh, I used to code a lot in ASP and in ASP form elements with identical names could be accessed through an array without having to define that array first.. I guess it made me lazy 😉

Thnx for your answer!

fuck!!

this is a neat trick if you know which items are posted.

I need a different kind of script, some script to walk through all posted elements or, even better, a script with which I can query all items at once, returning all values delimited by comma's..

[MAN]foreach[/MAN]

try using a hidden field for each checkbox and have same index and voila (again) 😃

thnx!

I finally was able to fix it like this:

	foreach($_POST as $varName => $value)
	{
		// check if we're delaing with the correct field
		if (is_numeric(strPos($varName, "userSiteID")))
		{	// find the psition of the underscore
			$pos = strPos($value, $needle);
			if(is_numeric($pos))
			{	$iUserID = (int)substr($value, 0, $pos);
				$iSiteID = (int)substr($value, $pos+1);
				// generate queries

		}
	}
}
