    Sessions using Javascript

    Hello everyone!

    I am new to JavaScript and have been using PHP, but needed to use a dynamic form for information about County/State. Here is part of the code (keep in mind I did all 50 states this way-that's well over 3000 counties):


    Code:
    </script><script language="JavaScript" type="text/javascript">
    <!--
    
    //first combo box
    data_1 = new Option("Alabama", "$");
    data_2 = new Option("Alaska", "$$");
    data_3 = new Option("Arizona", "$$$");
    
    //second combo box
    data_1_1 = new Option("Autauga", "-");
    data_1_2 = new Option("Baldwin", "-");	
    data_1_3 = new Option("Barbour", "-");
    data_1_4 = new Option("Bibb", "-");
    data_1_5 = new Option("Blount", "-");
    data_1_6 = new Option("Bullock", "-");
    data_1_7 = new Option("Butler", "-");
    data_1_8 = new Option("Calhoun", "-");
    data_1_9 = new Option("Chambers", "-");
    data_1_10 = new Option("Cherokee", "-");
    data_2_1 = new Option("Aleutians East", "--");
    data_2_2 = new Option("Aleutians West", "--");
    data_2_3 = new Option("Anchorage", "--");
    data_2_4 = new Option("Bethel", "--");
    data_2_5 = new Option("Bristol Bay", "--");
    data_2_6 = new Option("Denali", "--");
    data_2_7 = new Option("Dillingham", "--");
    data_2_8 = new Option("Fairbanks North Star", "--");
    data_2_9 = new Option("Haines", "--");
    data_2_10 = new Option("Juneau", "--");
    data_3_1 = new Option ("Apache", "--");
    data_3_2 = new Option ("Cochise", "--");
    data_3_3 = new Option ("Coconino", "--");	
    data_3_4 = new Option ("Gila", "--");
    data_3_5 = new Option ("Graham", "--");
    data_3_6 = new Option ("Greenlee", "--");
    data_3_7 = new Option ("La Paz", "--");
    data_3_8 = new Option ("Maricopa", "--");
    data_3_9 = new Option ("Mohave", "--");
    data_3_10 = new Option ("Navajo", "--");
    
    // other parameters
    	
        displaywhenempty=""
        valuewhenempty=-1
    
        displaywhennotempty="-select-"
        valuewhennotempty=0
    
    
    function change(currentbox) {
    	numb = currentbox.id.split("_");
    	currentbox = numb[1];
    
        i=parseInt(currentbox)+1
    
    // I empty all combo boxes following the current one
    
        while ((eval("typeof(document.getElementById(\"combo_"+i+"\"))!='undefined'")) &&
               (document.getElementById("combo_"+i)!=null)) {
             son = document.getElementById("combo_"+i);
    	     // I empty all options except the first one (it isn't allowed)
    	     for (m=son.options.length-1;m>0;m--) son.options[m]=null;
    	     // I reset the first option
    	     son.options[0]=new Option(displaywhenempty,valuewhenempty)
    	     i=i+1
        }
    
    
    // now I create the string with the "base" name ("stringa"), ie. "data_1_0"
    // to which I'll add _0,_1,_2,_3 etc to obtain the name of the combo box to fill
    
        stringa='data'
        i=0
        while ((eval("typeof(document.getElementById(\"combo_"+i+"\"))!='undefined'")) &&
               (document.getElementById("combo_"+i)!=null)) {
               eval("stringa=stringa+'_'+document.getElementById(\"combo_"+i+"\").selectedIndex")
               if (i==currentbox) break;
               i=i+1
        }
    
    
    // filling the "son" combo (if exists)
    
        following=parseInt(currentbox)+1
    
        if ((eval("typeof(document.getElementById(\"combo_"+following+"\"))!='undefined'")) &&
           (document.getElementById("combo_"+following)!=null)) {
           son = document.getElementById("combo_"+following);
           stringa=stringa+"_"
           i=0
           while ((eval("typeof("+stringa+i+")!='undefined'")) || (i==0)) {
    
           // if there are no options, I empty the first option of the "son" combo
    	   // otherwise I put "-select-" in it
    
    	   	  if ((i==0) && eval("typeof("+stringa+"0)=='undefined'"))
    	   	      if (eval("typeof("+stringa+"1)=='undefined'"))
    	   	         eval("son.options[0]=new Option(displaywhenempty,valuewhenempty)")
    	   	      else
    	             eval("son.options[0]=new Option(displaywhennotempty,valuewhennotempty)")
    	      else
                  eval("son.options["+i+"]=new Option("+stringa+i+".text,"+stringa+i+".value)")
    	      i=i+1
    	   }
           //son.focus()
           i=1
           combostatus=''
           cstatus=stringa.split("_")
           while (cstatus[i]!=null) {
              combostatus=combostatus+cstatus[i]
              i=i+1
              }
           return combostatus;
        }
    }
    
    //-->
    </script>
    That works fine, except for one problem. I am trying to put this information in a SESSION using PHP, but it isn't working. Here is that portion of my form code:

    Code:
    <html>
    <form action="statecounty.php" method="post">
    <TR>
    <TD>
    <FONT style="FONT-SIZE: 11pt" face=Arial>
    *State:
    </FONT>
    </TD>
    <TD>
    <select tabIndex="13" name="combo0" id="combo_0" onChange="change(this);" style="width:200px;">
    <option value="value1">-select-</option>
    <option value="value2">Alabama</option>
    <option value="value3">Alaska</option>
    <option value="value4">Arizona</option>
    </select>
    </TD>
    <TR>
    <TD>
    <FONT style="FONT-SIZE: 11pt" face=Arial>
    *County:
    </FONT>
    </TD>
    <TD>
    <select tabIndex="14" name="combo1" id="combo_1" onChange="change(this)" style="width:200px;">
    	<option value="value1">  </option>
    </select>
    </TD>
    </TR>
    </form>
    </html>
    And now "statecounty.php", my attempt to put the info in a session:

    Code:
    <?php
    session_start();
    
    //Form validation:
    
    if((!empty($_POST['combo1']))
    && (strlen($_POST['combo1']) < 30))
    {
    $county=$_POST['combo1'];
    $county=htmlspecialchars($county);
    $_SESSION['combo1'] = $county;
    }
    else
    {
    $errors[]= 'You forgot to enter a valid entry=County!';
    }
    
    if((!empty($_POST['combo0']))
    && (strlen($_POST['combo0']) < 30))
    {
    $state=$_POST['combo0'];
    $state=htmlspecialchars($state);
    $_SESSION['state'] = $state;
    }
    else
    {
    $errors[]= 'You forgot to enter your State!';
    }
    
    if (empty($errors))
    {
    header
    ("Location:http://www.thisnextpage.php");
    exit();
    }
    
    if (!empty($errors) && is_array($errors))
    {
    echo '<h1>Error!</h1>
    The following error(s) occured:<br/ >';
    foreach ($errors as $msg)
    {
    echo " - $msg<br />\n";
    }
    }
    
    ?>
    That part works just fine...and now the page that is supposed to pull the information:

    Code:
    <?php
    session_start();
    
    echo "{$_SESSION['combo1']}, {$_SESSION['combo0']}\n";
    
    ?>
    Any ideas on what I'm doing wrong?
    Thanks,
    ~Amy

    Okay, nevermind. Since I didn't get an answer, I joined a different forum and was able to get it figured out. Thanks anyway
