Problem for storing data for multiple selection, submission

szms

I am trying to get the user selection after all menu has been shown to the user and when the selections are done. Could you please let me know how to get all those information at the end. The way I did it just work for the last menu selection. I suppose I have to use some sort of array but don't know exactly how to do that. I will appriciate your suggestion. Thank you.

Take a look of my complete code:


<html> 
<title> 
Menu test 
</title> 
<body> 
<script type="text/javascript"> 
<!-- 
function updateTextBox(selectObj, textBoxObj) 
{ 
    var index = selectObj.selectedIndex; 
    var selection = selectObj.options[index].text; 
    textBoxObj.value += selection + "\n"; 
} 
// --> 
</script> 
<!-- <form name = "myform" action="CheckInsertedItems.php" method="POST"> --> 
<?php 
extract( $_GET ); 

if( !isset($submit))// do this if no GET vars 
{ 
    print "<form method=\"GET\">"; 
    print "<p>Enter in the number of times below:</p>"; 
    print "<input type=\"text\" name=\"number\" size=\"30\">"; 
    $menu_counter = 0; 
    print "<input type='hidden' name='menu_counter' value=$menu_counter>"; 
    print "<input name=\"submit\" type=\"submit\" value=\"send\">"; 
    print "<input name=\"reset\" type=\"reset\" value=\"reset\">"; 
    print "</form>" ; 
} 
else 
{ 

if( $number>0 ) 
{ 
    $months = array("January","February","March","April","May","June","July",  "August","September","October","November","December"); 

    $number = $HTTP_GET_VARS["number"]-1; 
    $menu_counter =$HTTP_GET_VARS["menu_counter"]+1; 
    print "<form   method=\"GET\">"; 
    print "Select components for term $menu_counter<br>"; 
?> 
        <select size="5" name="user_choice" onclick="updateTextBox(this, currentSelections)"><?php 
        foreach ($months as $Existing_Item) 
        { 
            print "<option value=\"$Existing_Item \">$Existing_Item</option>"; 
        } 
        print "</select>"; 
        print "<br>"; 
?> 
        <select size="5" name="user_choice" onclick="updateTextBox(this, currentSelections)"> 
        <?php 
        foreach ($months as $Existing_Item) 
        { 
            print "<option value=\"$Existing_Item \">$Existing_Item</option>"; 
        } 
        print "</select>"; 
        print "<br>"; 
        ?> 
        <textarea name = 'currentSelections' readonly="readonly" rows = "3" cols = "20"></textarea> 
        <br> 
<?php

-----------Trying to store the data in an array--------------
//$Selected_Array[] = $currentSelections;

print "<input type='hidden' name='Selected_Array[]' value=$currentSelections>";

 

print "<input type='hidden' name='number' value=$number>"; 
        print "<input type='hidden' name='menu_counter' value=$menu_counter>"; 
        print "<input name=\"submit\" type=\"submit\" value=\"submit\">"; 
        print "<input name=\"reset\" type=\"reset\" value=\"reset\">"; 
        print "</form>"; 
    } 
    else 
    { 
        // do whatever happens after the number of forms has been filled

--------Trying to show the selected items----------
print "<br>You choice are: <br>";
$Selected_Array = $HTTP_GET_VARS["Selected_Array"];
foreach($Selected_Array as $name)
{
print "$name";
}

Thank you very much for your revised code. Could you please let me know what do we need to use the following three things?

<pre>
print_r( $GET ) and
extract( $GET );

I am getting warning after hitting the submit when user gives a number for the first execution. It would be great if you let me know the reason of getting warning. Thank you very much Sir.

Warning: Invalid argument supplied for foreach() in /usr/local/menutest8.php on line 83

the line is the begining of the following for loop

 
foreach($results as $res)
        {
                echo "<input type='hidden' name='results[$i]' value='$res'>";
                $i++;
        }

HalfaBee

Add this

     $i=0;
     if( isarray( $results ) )
          foreach( $results as $res )
          {
             echo "<input type='hidden' name='results[$i]' value='$res'>";
             $i++;
          }

You are great. I wish one day I will be a gig like you in PHP. Bye the way you didn't tell me about the following three things.

<pre>
print_r( $GET ) and
extract( $GET );

I am not using print_r( $GET ) and extract( $GET ) in my code and it's working fine.

I also want to know how I can differentiate the items whether it is selected from top menu or bottom menu. Thank you.
