Form Validation, Text Fields

[meganp]

Hi,

I have validated radio buttons and checkboxes, but how would I validate that at least one Qty box (in the type="text" boxes) has a value entered (this is a shortened version of the form, there are actually at least 10 qty's) since each name is different? I know there must be another way other than validating each one individually.

<form name="premier" method="post" action="../forms/proc_pgpkg3.php">
<table width="720" border="0">
  <tr align="center"> 
   <td colspan="3"><h3>Package Selection</h3> 
    <p>You can choose from several options for your monthly package.</p>
    </td>
  </tr>
 <tr>
  <td class="right">&nbsp;</td>
  <td>&nbsp;</td>
  <td>&nbsp;</td>
 </tr>
 <tr>
   <td class="right"><strong>ID No.:</strong></td>
  <td>&nbsp;</td>
  <td><input name="ID" type="text" id="ID" size="15">
  </td>
 </tr>
 <tr>
   <td class="right"><strong>Name:</strong></td>
  <td>&nbsp;</td>
  <td><input name="Name" type="text" id="Name" size="60"></td>
 </tr>
 <tr>
   <td class="right"><strong>E-Mail Address</strong>:</td>
  <td>&nbsp;</td>
  <td><input name="Email" type="text" id="Email" size="60"></td>
 </tr>
 <tr>
   <td class="right"><strong>Phone Number:</strong></td>
  <td>&nbsp;</td>
  <td><input name="Phone" type="text" id="Phone" size="60"></td>
 </tr>
 <tr>
  <td class="right">&nbsp;</td>
  <td>&nbsp;</td>
  <td>&nbsp;</td>
 </tr>
 <tr>
  <td class="right"><input type="radio" name="Autoship" value="Package_Selection"></td>
  <td>&nbsp;</td>
  <td>Below is my selection for the Autoship Package</td>
 </tr>
 <tr>
  <td class="right"><input type="radio" name="Autoship" value="Change"></td>
  <td>&nbsp;</td>
  <td>I am changing my previous Autoship Package selection</td>
 </tr>
 <tr>
  <td class="right"><input type="radio" name="Autoship" value="Separate_Selections"></td>
  <td>&nbsp;</td>
  <td>I would like to purchase the following package(s) separately from my
   Autoship</td>
 </tr>
 <tr>
  <td height="20" colspan="3">&nbsp;</td>
 </tr>
 <tr>
   <td width="110" height="55" class="right"> 
    PG0401 <br>
    <strong>$38.00</strong><br>
    <input name="Qty_PG0401" type="text" id="Qty_PG0401" size="3">

  <td width="593"><p><strong>Candles</strong><br>
     Descriptive text here. <em>Selection
        may vary.</em></p>
   </td>
 </tr>
 <tr>
  <td class="right">   PG0407 <br>
    <strong>$36.00</strong><br>
    <input name="Qty_PG0407" type="text" id="Qty_PG0407" size="3">
 Qty</td><td>&nbsp;</td>
   <td><strong>Casual Gifts</strong><br>
    Descriptive text here. <em>Selection 
    may vary.</em></td>
 </tr>
 <tr>
  <td class="right">PG0410<br>
   <strong>$34.00</strong><br>
   <input name="Qty_PG0410" type="text" id="Qty_PG0410" size="3">
   Qty</td><td>&nbsp;</td>
  <td><strong>Gift Wrap</strong><br>
  Descriptive text here. <em>Selection may vary.</em></td>
 </tr>
 <tr>

  <td>&nbsp;</td>
  <td><input type="submit" name="Submit" value="Submit">

Thank you for any assistance.

You could use javascript. Get a reference to the form. Then loop through the form's elements. Where type = text, do an if to see if any of those elements has a value. If so, break. If not, throw up a message to the user, or whatever other action it is that you plan to take.

Thanks... I'm not too literate in Javascript and looping through forms, etc., but I managed in the meantime to accomplish what I wanted (although I did have to do each individually) with this:

// check that at least one quantity is entered
   if (window.document.premier.Qty_PG0401.value < 1 &&
   window.document.premier.Qty_PG0407.value < 1 &&
 window.document.premier.Qty_PG0410.value < 1)
 {
   alert ("You did not enter a quantity.");
 return false;
 } 
 return true; 
}

When I tried other ways (before posting), I ended up with an array and had a lot of trouble retrieving the values properly with php.

Thanks again,
