Using sessions to capture checkbox options and pass then to a popup.

[smitho]

I've done a search and although the process of passing data from a popup back to the main window has been discussed I have not been able to get this to work.

 

I have the process in 3 parts.

 

boxesPage1.php gives the user 4 check boxes to choose from.

 

boxesPage2.php displays the choices made in a text field as an array. This page also has an update link to allow user to edit the choice they made.

 

boxesPage3.php is a popup that the user can use to change the box selection they made and then take them back to boxesPage2.php.

 

It's seems to be working until I get to the part where the changes in the popup are applied back to the boxesPage2.php. Although I don't get the updated results if I click on the update link a second time the popup will appear with the altered choices which mean I am holding the choices I just need to pass then back to the results page (2).

 

If anyone could point out where I'm going wrong it would be appreciated.

 

boxesPage1.php

<?php 

//Set the boxes to unchecked
$box1='unchecked';
$box2='unchecked';
$box3='unchecked';
$box4='unchecked';

?>

<!--create form-->
<form enctype="multipart/form-data" method="post" action="boxesPage2.php">
  <table width="0%" border="0">
    <tr>
      <td><input type="checkbox" name="box1[]" value="box1"<?PHP print $box1; ?>>Checkbox1</td>
      <td><input type="checkbox" name="box1[]" value="box2"<?PHP print $box2; ?>>Checkbox2</td>
      <td><input type="checkbox" name="box1[]" value="box3"<?PHP print $box3; ?>>Checkbox3</td>
      <td><input type="checkbox" name="box1[]" value="box4"<?PHP print $box4; ?>>Checkbox4</td>
    </tr>
  </table>
<br>
<br>
    <input name="check" type="submit" id="send" value="Send File" />
    <label></label>
</form>

 

boxesPage2.php

<?php

//start session to capture the choices made in the first screen and pass them on the update screen.
session_start(); 
if (isset($_POST["check"])) {

$box=$_POST["box1"]; //as a normal var
$box_count=count($box); // count how many values in array


foreach ($box as $cat) {
	echo $cat." - ";
}

//check the array
echo "<hr>";

}
echo "<br>";

$_SESSION['boxes']=$box;

?>
<!--display the choices-->
<form action="checkmeta.php" method="post" enctype="multipart/form-data" name="checklist">
  <label>Choice
  <input name="boxid" type="text" id="boxid" value="<?php foreach ($box as $cat) {echo $cat." - ";}?>" />
</label>
<a href="boxesPage3.php<?php echo htmlspecialchars(SID); ?>" onclick= "window.open('boxesPage3.php', 'window_name', 'width = 800, height = 250');return false;">UPDATE BOXES</a>
</form>  

 

boxesPage3.php

<!--JS to close the popup and go back to the second screen-->
<script language="JavaScript">

function refreshParent() {
		window.opener.location.href = window.opener.location.href;

			if (window.opener.progressWindow)

{
		window.opener.progressWindow.close()
}
		window.close();
}

</script>
<?php
//get the choices made and shown in the second screen 
session_start();

$box1='unchecked';
$box2='unchecked';
$box3='unchecked';
$box4='unchecked';

$box = $_SESSION['boxes'];


//check the boxes if they were checked or not.
foreach ($box as $value) {

if($value == 'box1'){
$box1='checked';
}
if($value == 'box2'){
$box2='checked';
}
if($value == 'box3'){
$box3='checked';
}
if($value == 'box4'){
$box4='checked';
}		
}

$_SESSION['boxes']=$box;

?>

<form enctype="multipart/form-data" method="post" action="boxesPage2.php">
  <table width="0%" border="0">
    <tr>
      <td><input type="checkbox" name="box1[]" value="box1"<?PHP print $box1; ?>>Checkbox1</td>
      <td><input type="checkbox" name="box1[]" value="box2"<?PHP print $box2; ?>>Checkbox2</td>
      <td><input type="checkbox" name="box1[]" value="box3"<?PHP print $box3; ?>>Checkbox3</td>
      <td><input type="checkbox" name="box1[]" value="box4"<?PHP print $box4; ?>>Checkbox4</td>
    </tr>
  </table>
<br>
    <input name="check" type="submit" id="send" value="Send File" onclick="refreshParent(<?php $_SESSION['boxes']=$box;?>)" />
    <label></label>
</form>

OK one step closer.

 

On boxesPage2.php after

 

if (isset($_POST["check"])) {
........
}

I've added.

else
{
$box = $_SESSION['boxes2'];
}
echo "<br>";

$_SESSION['boxes']=$box;

print_r($box);

 

To get this data on boxesPage3.php I've added this line.

 

$_SESSION['boxes2']=$box;

 

I don't get the error Notice: Undefined variable: box in ....on line  (which was ->$_SESSION['boxes']=$box;)

 

But to get it to work I have to click on the update link make my change in the popup submit to go back to the main window (no change) click on the update link a second time and just click on the submit button again then the change has taken place. Should this not occur the first time?

Can anyone tell me if there is a way to check that once I click on the submit button on the popup that the check boxes I've selected are captured.  I don't understand why it doesn't apply the first time I change the options in the popup but it does the second time I update them.

 

Any suggestion would be appreciated.
