    validate button radio in form

    Hello,

    I use php and javascript on a form.
    My validate script doesn't work with radio button. What's wrong? I
    want to be sure that one of the button is press. M or F

    I get on my first page:

    <?php
    $Genre=$_POST['genre'];
    ?>
    <head>
    <script type="text/javascript">
    function verif_champs()
    {

    if(document.for ml.Genre.value == "")
    {
    alert("Choose the gender!");
    document.forml. Reference.focus ();
    return false;
    }
    </script>
    </head>
    <body>
    <form name="forml" method="post" onSubmit="retur n verif_champs()"
    action="test22. php" >
    <table>
    <tr><td>
    <?
    $checked[$_POST['Genre']]='checked="chec ked"';
    echo '<input type = "radio" name="Genre" value="F"
    '.$checked['F'].'/>';
    echo '<input type = "radio" name="Genre" value="M"
    '.$checked['M'].'/>';
    ? <input type="submit"></td></tr>
    </table>
    </form>

    On my page 2:

    <?php
    $Genre=$_POST['Genre'];
    ?>
    <body>
    <table>
    <tr><td>
    <form name="form2" ACTION="test11. php" method="post">
    <? foreach ($_POST as $key=>$val)
    {
    echo '<input type = "hidden" name="'.htmlent ities($key).'"
    value="'.htmlen tities($val).'" />';
    }
    ?>
    <? echo $Genre ?>
    <input type="submit" name="Submit2" value="Back" />
    </form>
    </td></tr></table>
    </body>

    Thanks a lot. Pascal

      Where is the closing } for this function?

      echo '<input type = "radio" name="Genre" value="M"

      ? <input type="submit"></td></tr>

      </form>
      </td></tr></table>

              function verif_champs()
              {
              >
              if(document.for ml.Genre.value == "")
              {
              alert("Choose the gender!");
              document.forml. Reference.focus ();
              return false;
              }
              For a multiple elements with same name, the element becomes
              collection. It can be accessed like an array. Use some code like:

              function verif_champs(f)
              {
              var z=f.elements['Genre'];
              var y=z.length;
              while (y--)
              {
              if (z[y].checked)
              {
              return true;
              }
              }
              alert('choose genre');
              return false;
              }
              <form name="forml" method="post" onSubmit="retur n verif_champs()"
              action="test22. php" >
              The form declaration should give parameter to the new function

              <form name="forml" method="post" onSubmit="retur n verif_champs(th is)"
              action="test22. php" >
