PHP - Moved: How Do I Display Questions From Checkboxes?
This topic has been moved to Third Party PHP Scripts.
http://www.phpfreaks.com/forums/index.php?topic=350021.0 Similar TutorialsHi, I have a set of checkboxes a bit like a checklist and I then want the items that aren't checked to displayed. On the first page, I have this code: <? while($row = mysql_fetch_array($result)) { ?> <form action="packed.php" method="post"> <div> <label><input type="checkbox" name="<? echo stripslashes($row['checklistitem']); ?>" value="yes"> <? echo stripslashes($row['checklistitem']); ?> </label> </div> This basically takes an array from a database. The info is then posted to the next page which hopefully will display the boxes which are 'unticked' or unchecked if you will. The code I have on the second page is: <?php $query_string = ""; if ($_POST) { $kv = array(); foreach ($_POST as $key => $value) { $kv[] = "$key"; } $query_string = join("<br />", $kv); } else { $query_string = $_SERVER['QUERY_STRING']; } echo $query_string; ?> At the moment, it returns the array items that were checked but I want the unchecked ones to be shown. Is that possible? Thanks very much! -Steve <?php echo $error_msg=''; if(isset($_POST['submit'])) { $LoginId=$_POST['LoginId']; $Password1=$_POST['Password1']; $Password2=$_POST['Password2']; $Name=$_POST['Name']; $Age=$_POST['Age']; $BloodGroup=$_POST['BloodGroup']; $Sex=$_POST['Sex']; $Qualification=$_POST['Qualification']; $Email=$_POST['Email']; $Address=$_POST['Address']; $AboutYourself=$_POST['AboutYourself']; [b]$countCheck=count($_POST['checkbox']); echo $countCheck;[/b] //$checkbox=$_POST['checkbox']; //$countCheck=count($checkbox); if(empty($LoginId)){echo 'Please enter Login Id';} elseif(empty($Password1)){echo 'Please enter Password';} elseif(empty($Password2)){echo 'Please confirm Password';} elseif($Password1!==$Password2){echo 'Password didn\'t match';} elseif(empty($Name)){echo 'Please enter Name';} elseif(empty($Age)){echo 'Please enter Age';} elseif(empty($Sex)){echo 'Please enter Sex';} elseif(empty($Qualification)){echo 'Please enter Qualification';} elseif(empty($Email)){echo 'Please enter Email';} elseif(empty($Address)){echo 'Please enter Address';} elseif(empty($AboutYourself)){echo 'Please enter About Yourself';} [b]elseif($countCheck==0){ echo 'You have to register at least one activity.';}[/b] else { $dbc=mysqli_connect('localhost','root','','nog'); $query="select * from registration where LoginId='$LoginId'"; $result=mysqli_query($dbc,$query); if(mysqli_num_rows($result)==0) { $checkbox=$_POST['checkbox']; $countCheck=count($_POST['checkbox']); $reg_id=' '; for($i=0;$i<$countCheck;$i++) { $reg_id=$reg_id.$checkbox[$i].','; } $query="insert into registration (LoginId,Password,Name,Age,BloodGroup,Sex,Qualification,Email,Address,AboutYourself,Activity)values ('$LoginId',SHA('$Password1'),'$Name','$Age','$BloodGroup','$Sex','$Qualification','$Email','$Address','$AboutYourself','$reg_id')"; $result=mysqli_query($dbc,$query) or die("Not Connect"); echo ' Dear '.$Name.'.<br>Your Account is waiting for approval<br>'; echo "<a href='RegistrationAndActivity.php'>Back to Home</a>"; //header('Location: index.php'); // header('Location: Registration.php'); } else { echo 'Dear '.$Name.

As result/row is retuned to the user i would like to be able to detect whether or not they have checked a checkbox at the end of each rown in which case multiple rows can then be deleted from the database upon the user clicking a 'delete multiple records' button. I have no problem in being able to display the checkboxes on the webpage but i am a little unsure as to how to refernce them and detect which ones the user has checked. Given my database stores hostnames/IP addresses would it be best to name each checkbox to reflect the hostname or name the value it returns when checked to reflect the hostname. Given the above and that I also store the results of a users search in a $_SESSION['hosts'][][] array how can I then tie the two together? Thanks for reading.
