[SOLVED] Problem with ForEach loop in form

psychowolvesbane · January 10, 2008

I have this validation for 2 groups of check buttons in a big form, the code for the check buttons is here:

<fieldset style="padding: 2">
     <legend>Available Sizes
     </legend>
     <table  border="1" id="Sizes">
        <tr>

        <?php

        $X=0;
        
        while($X!=6)
        {
           $Size = $CBSizes[$X];
           ?>
   <td><?php echo $Size?>:</td>
   <td><input type="checkbox" name="Sizes[]" value="<?php echo $Size?>"></td>
           </tr>
           <tr>
           <?php
           ++$X;
        }
        ?>
     	</tr>
     </table>
    </fieldset>
    <br>
    <br>
    <fieldset style="padding: 2">
     <legend>Available Colours</legend>

     <table border="1"><tr>

      <?php
      //Establish a connection to the Database

      $conn = mysql_connect($Host,$Username,$Password);

      $db = mysql_select_db($Dbname, $conn);

      $sql = "SELECT AvailableColours FROM Colours ORDER BY AvailableColours";
   
      $rs = mysql_query($sql, $conn) or die(mysql_error());

      $NumberOfColours = mysql_num_rows($rs);

      $counter = 0;

      if ($result || (mysql_num_rows($rs) > 0))
      {
         while ($row = mysql_fetch_assoc($rs)) 
         {    
            if($counter%9==0&&$counter!=0) echo "</tr><tr>";
            echo "<td><img src='/images/colours/{$row['AvailableColours']}.gif' /><br />";
            echo "<td><input type='checkbox' name='Colours[]' value='{$row['AvailableColours']}'></td>";
            echo "</td>";
            ++$counter;
         }
      }
      echo "</tr></table>";
     
     mysql_close($conn); 
     ?>
    </legend>
   </fieldset>

The validation for this code once submitted is here, it is located above the <html> tags:

   $CBSizes = array("Small", "Medium", "Large", "XL", "XXL", "3XL");

   $AColours = $_POST['Colours'];

   $ASizes = $_POST['Sizes'];

   //Available Sizes Section

   if(count($ASizes) > 0)
   {
      foreach($ASizes AS $Sizes)
      {
         $Valid_ASizes=True;
         $AvailableSizes .=$Sizes."?";
         echo $AvailableSizes;
      }
   }
   else 
   {
      $Valid_ASizes=False;
      echo "Please select a size!<br>";
   }
   
//Available Colours Section

   if(count($AColours) > 0)
   {
      foreach($AColours AS $Colours)
      {
         $Valid_AColours=True;
         $AvailableColours .=$Colours."?";
         echo $AvailableColours;
      }
   }
   else 
   {
      $Valid_AColours=False;
      $ValidForm = False;
   }

Now what is is supposed to do is output each value into a string that has been concatenated, and each value is separated with a ?. Now what happens with that code is that it seems to repeat all previous values plus the new one each time instead of just adding the new value on top of the previous ones.

An example of the values of each are:

(6) selections made for Size:

Small?Small?Medium?Small?Medium?Large?Small?Medium?Large?XL?Small?Medium?Large?XL?XXL?Small?Medium?Large?XL?XXL?3XL?

(4) Selections made for Colour:

Ash?Ash?ForestGreen?Ash?ForestGreen?Natural?Ash?ForestGreen?Natural?SteelBlue?

Can you tell me what is going wrong?

Is this solved or do you still need help?

If you do, then for starters, you're echoing $AvailableSizes everytime the for loop runs, so obviously there will be many duplicates like that.

Yes it is working, I've had a long day sorry about the useless topic.
