I am new to php and I thought it best to start by using a CMS and creating small functions to extend it's functionality. I will start by explaining the situation around what I want to do. I am trying to create a module for the drupal CMS. The module I am trying to create I am creating for my girlfriends son (for when it is complete he will be the one maintaining it through the web interface). He wants a game server (WOW) and a web site that once they create an account on the web site it will create an account on the game server as well. If I understand the way this works correctly for this game server to work you need a logon database and then a character and world database for each realm you have. With that basically what happens is you go to the drupal web site and click create account, input a username, email address and password and agree to terms of service. Then drupal does some checks and writes the information to the drupal database and with the module I creating it will write to the logon database as well. I am working on the admin forms so you can edit how many realms the server has the sql statement to login to the game and add and delete realms. I have been looking at an example of a form for drupal here http://drupal.org/node/717746 but have converted it to my purpose and it brings up some questions here is what I have so far:

function wowcp_gameserver_settings($form_state) {

If max_realms is set to a large number the way I see it you would have to hard code everything into the php file. Instead of that could you not remove from the if(isset) and have it that when they click on the add realm button check to make sure the textfield contains a number if it doesn't return an error if it does contain a number make sure it is not greater then max_realms and then use a start count and adding that number to all the arrays for that realm and validate all the information is what you expect. I think this would work for adding realms, I think where the problem would come in is in deleting realms (or it could be me over thinking it). For example if you have max_realms set to 4 you could have 5 the one default one that can't be deleted plus 4 others and the ones that can be deleted would be called realm1 - realm4 if you delete the first 2 you would minus count by 2 so if you clicked add realm again it would try and create realm3 which already exists. Is there another way on doing this that you could create the realms and delete them and it not try to add realms with the same array name?

Hello there!!!

I am taking my first steps into php and html code and i am facing a problem. I am making a form in order for the user to create a new category in my page but i don't know how many Attributes the category will have. So i made a field for the Attribute followed by a radio tha chooses if the Attribute is measurable or unmeasurable. After that I have set a Button in order to regenerate it with JavaScript as many times as necessary.

this is the html code:
Code: [Select]
<form name="Create Category" align="center" action="Assets/register_test.php" method="post">
  <table style="margin-left: 40%;" id="Attributes">
    <tr> <h2 align="center">Attributes</h2> </tr>
    <tr class="feed" align="left">
      <td> <input style="margin-top: 3px;" type="text" name="Attribute" size="30"> <br/>
         <form align="center">
           <input type="radio" name="var" value="measurable" /> measurable
           <input type="radio" name="var" value="unmeasurable" /> unmeasurable
         </form>
       </td>
    </tr>
  </table>
  <div id="attr" style="display:none"> 
      <div class="feed"> 
        <input type="text" name="Attribute[]" value=""  size="30"> 
          <form>
            <input type="radio" name="var" value="measurable" /> measurable
            <input type="radio" name="var" value="unmeasurable" /> unmeasurable
          </form>
      </div> 
  </div> 
  <a style="height: 25px; margin-left:48%; margin-top: 20px;" href="javascript:add_feed()">Add New </a>   
  <input style="height: 25px; margin-left:48%; margin-top: 20px;" type="submit" value="Submit" onclick="validateFields()">
  <input style="height: 25px; margin-left:48%; margin-top: 20px;" type="reset" value="Reset"> <br/>
</form>
this is my JavaScript:

Code: [Select]
function add_feed() 
{ 
    var div1 = document.createElement('div'); 
 
    // Get template data 
    div1.innerHTML = document.getElementById('attr').innerHTML; 
 
    // append to our form, so that template data 
    //become part of form 
    document.getElementById('Attributes').appendChild(div1); 
 
} 
The problem is the Reset button. When i hit the Reset button everything gets erased in all the text-inputs But the radios (except the first one) don't.

Is there is anyone who can help please?

Im displaying the results of a database by using a while loop... so Im trying to figure out how to delete some entries from the datbase. What I wanted to do is add a button in each result that will have the value "delete"... but I cant figure out how to do this. Im kinda new to mysql. I just want it so when I click the button the result will get deleted from the database.

I did some research on this but I cant really grasp the examples.

Can anybody help me out with this one?

Thanks!

So, I just don't know where to post this question. I've written a quiz program where 50 English vocab words are pulled from a dB and displayed on one page with the order scrambled. My students then type the Spanish translation for each. When they submit the form the next page grades their work. They have to get a 90 or better for the grade to be automatically recorded, so I want them to click the back button and go back and make corrections. The problem is when they use a Chrome browser and click the back button the program re-sorts the order of questions. It leaves the order of their answers the same. So what they answered for number 1 is still in the field for number 1, but the questions (the English vocab word) is different. Chrome does this consistently so I thought this was a Chrome issue only. Then one of my students said the same thing happened to her when using Safari.

So here is my question, how can I stop Chrome (or any other browser) from re-running my server-side PHP scripts (re-sorting the vocab array) when clicking the back button?

 

Here is the code for students taking the quiz:

<form method="post" action="portal.php?load=vquiz_grade" style="margin-left: 50px; line-height: 30px;">

    $count = 1;
    $query = "SELECT * FROM inno_memorize WHERE uname = 'admiralq' AND subject = '$subject' AND title = '$title' ORDER BY subject, title";

    while ($row = mysql_fetch_array($result)){
        $ans[$count]['def'] = $row['definition'];
        $ans[$count]['word'] = $row['vocab_word'];
        $count++;
    }

    $max = $count-1;
    shuffle($ans);
    
    $count = 0;
    while ($count < $max){

        $loc1 = strpos($ans[$count]['word'], "(");
        $loc2 = strpos($ans[$count]['word'], ")");

Folks,

 

Look at this weird thing.

I load the page and get echoed as expected: Did Not REQUEST_METHOD!

Then, I click the SUBMIT button and to my astonishment I get echoed: Did Not POST->Submit!

Got 2 buttons. Same result whenever clicking any.

Why is that ?

Hi i am working one of my assignment for school.. i just studied php..

my problem is, is it possible to load another form once i clicked a radio button?
if its a yes... can you teach me how to do that?

thank you!

Dear All

I have a form say i have selected Volva from drop down box . So without clicking on submit button  when i move to next field that is `<input>` the value that is volva should get store in php variable

<html>
<body>

<form action="">
<select name="cars">
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="fiat">Fiat</option>
<option value="audi">Audi</option>
</select>

<input type="text" name="abc" />
</form>

</body>
</html>

So I am trying to execute an sql query by clicking a button or a link. Ultimately I want users to be able to click the "Fav" button and it then fades into "Added to favorites!" (I am building a favorite system which first collects data on page load like userid and itemid and then it needs to send it to the DB after a button is clicked)

The fade and stuff is not the most important part now (although a tip on doing that would be awesome) but the most important part is how to get this functional:
PHP Code:
        <?php 
    // Start Favorite System!
        $user =& JFactory::getUser();
        $userid = $user->id;
        if ($userid == 62) {
            echo "userID: ".$userid."<p />";
            if ($user->guest) {echo "You are a guest<p />";}
            $itemid = $this->item->id;
            echo "itemID: ".$itemid."<p />";
            $catid= $this->item->category->id;
            echo "catID: ".$catid."<p />";
            
            $query = "INSERT INTO jos_k2_fav_xref (userID, itemID, catID) VALUES ('$userid', '$itemid', '$catid')";

            // Need a way to make this into a button
            $run = mysql_query($query) or die(mysql_error());
        } else {}


        ?>
Currently all the values get stored in the DB as the page is loaded. I however want to be able to click on something to execute that query how do i do that? I read a bunch of stuff on javascript and ajax but it got me nowhere...

Help is greatly appreciated!

Hi, I am creating an access control page where my end user swipes his card and the page auto submits. At this stage I want to click his/her picture as well. The challenge is I am unable to find a script where a webcam clicks on page refresh or when it auto submits.. All the scripts i have seen only work on a click which is not possible here as the only user input is a swipe which has an autosubmit.

this is my code so far...

Code: [Select]

<form action="<?php if ($_SESSION['reply_has_been_clicked'] != '1') { echo '';} elseif ($_SESSION['reply_has_been_clicked'] == '1') {echo 'thread_redirect.php';}?>" method='post'>
<?php
$_SESSION['current_thread'] = $the_thread_title . '.php';
if (($_SESSION['logged_in'] == '1') && (isset($_POST['reply_to_thread'])) && ($_SESSION['reply_has_been_clicked'] != '1')) {
echo "<textarea name='thread_reply' style='resize:none;' cols='75' rows='10'>Enter your reply here...</textarea>";
echo "<br>";
$_SESSION['reply_has_been_clicked'] = '1';
} elseif (($_SESSION['logged_in'] != '1') && (isset($_POST['reply_to_thread']))) {
$reply_echo = 'You need to be logged in!';
}
?>
<input type='submit' name='reply_to_thread' value="Reply">
<?php
echo $reply_echo;
?>

so this works but it takes three button pushes to do the job. I can't think of anyother way to do it. help please!
