[RESOLVED] how do i find out if user enters "no"

nissa

Hello,

I am new to PHP and am currently updating someone else's web tool. I have found contradicting information regarding this issue and would appreciate any guidance in how to solve this problem.

I need the functionality that if the user has selected "no" for both of the options below, a specific part of the form should not be visible to them (by default it should also not be visible).

I have written a Javascript function that will handle this but have no idea how to properly return this information to PHP, or if PHP can get this information itself??? Any help is greatly appreciated. Please let me know if you require more information.

Thanks,

Nissa

PHP/HTML code:


<tr>
          <td style="font-size: 9pt" nowrap><b>Server Required</b></td>
      <td class="grey">
            <table border="0" cellpadding="0" cellspacing="0">
	<tr><td>
<?php
$serverreqoptions = Array (0=>"No", 1=>"Yes");
doselectbox($serverreqoptions, $bdprow[14], false, "serverrequired", false, true);
?>
		<td></tr></table>
	      </td>
	    </tr>

    <tr>
          <td style="font-size: 9pt" nowrap><b>Storage Required</b></td>
      <td class="grey">
            <table border="0" cellpadding="0" cellspacing="0">
	<tr><td>
<?php
$storagereqoptions = Array (0=>"No", 1=>"Yes");
doselectbox($storagereqoptions, $bdprow[14], false, "storagerequired", false, true);
?>
		<td></tr></table>
	      </td>
	    </tr>
   <tr>
              <td class="th1" width="1"><img border="0" src="images/Expanded16.gif" width="16" height="16" onclick="expand(event)"></td>
              <td class="th1">Actions Change</td>
            </tr>
            <tr>
              <td width=1></td>
              <td class="th1">
              <table border="0" cellspacing="0" width="100%">

[COLOR=Red]<!-- would like to put some type of if statement just before the for loop that returns true if  either  server/storage are  required and sets phase to start at 0 -->
[/COLOR]

<?php
$votephases = array ("A", "B", "C", "D");
for ($phase = 1; $phase < 4; $phase++) {

?>
                <tr>
                  <td>
<?php startExpandSection($votephases[$phase], ($bdprow[0] == $phase)); ?>

Possible Javscript Function:

//note I realize this won't work when I wrote this the options were radio buttons
//this is here to show the idea behind what I want to do
function required(server, storage){

var servernoid = document.getElementById(server);
var storagenoid = document.getElementById(storage);

//if both checked "no" then isn't required
if(servernoid.checked == true && storagenoid.checked == true){
	return false;
}
else
	return true;
}

just check for the $POST values (or $GET depending on your forms method)

$_POST['name'] will catch the name of whatever fields have values associated with them. You can check the value of a variable say

so $_POST['confirm'] could hold the value you wanted and you can check if it holds yes or whatever you want.

 if($_POST['confirm']=="yes"){
    eat_babies("only the green ones");
 }

Hello nemesis1931,

Hey thanks for your help I got it to work, but realized that my logic was wrong. I need php to always create that part of the table, therefore this was completely a Javascript problem. I've changed my code so that <body onload="hidethispart()"> will ensure it's hidden at first and in the select boxes <select onchange="thisisrequired()"> will handle if it needs to show or not. Thanks for helping anyways, apparently I didn't have enough coffee yesterday.
